"The world is so small . . . till it ain't." (Mac Miller)
(My son's photograph)
Zigermeet 2016, The Lockheed P-38 Lightning was a World War II American piston-engined fighter aircraft. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a central nacelle containing the cockpit and armament. Allied propaganda claimed it had been nicknamed the fork-tailed devil (German: 'der Gabelschwanz-Teufel') by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese.[7] The P-38 was used for interception, dive bombing, level bombing, ground attack, night fighting, photo reconnaissance, radar and visual pathfinding for bombers and evacuation missions[8] and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the aircraft of America's top aces, Richard Bong (40 victories), Thomas McGuire (38 victories) and Charles H. MacDonald (36 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs, toward the end of the war.[9][10]
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving and could be mishandled in many ways but the rate of roll in the early versions was too slow for it to excel as a dogfighter.[11] The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.[citation needed] At the end of the war, orders for 1,887 more were cancelled

Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Nakajima J1N1-S Gekko (Moonlight) IRVING:
Originally designed as a three-seat, daylight escort fighter plane by the Nakajima Aeroplane Company, Ltd., and flown in 1941, the IRVING was modified as a night fighter in May of 1943 and shot down two American B-17 bombers to prove its capability. The Gekko (meaning moonlight) was redesigned to hold only two crewmen so that an upward firing gun could be mounted where the observer once sat. Nearly five hundred J1N1 aircraft, including prototypes, escort, reconnaissance, and night fighters were built during World War II. A sizeable number were also used as Kamikaze aircraft in the Pacific. The few that survived the war were scrapped by the Allies.
This J1N1 is the last remaining in the world. It was transported from Japan to the U.S. where it was flight tested by the U.S. Army Air Forces in 1946. The Gekko then flew to storage at Park Ridge, IL, and was transferred to the Smithsonian Institution. The restoration of this aircraft, completed in 1983, took more than four years and 17,000 man-hours to accomplish.

Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Boeing B-29 Superfortress "Enola Gay":
Boeing's B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the first bomber to house its crew in pressurized compartments. Although designed to fight in the European theater, the B-29 found its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.
On August 6, 1945, this Martin-built B-29-45-MO dropped the first atomic weapon used in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.

I didn't buy the whole set of tools (though I keep thinking about it, sigh), but I like paint cans, so I bought both the A & B versions. They're about 1 1/2 inches tall, so they would work nicely in dioramas in multiple sizes.
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.
My father, Norman M Reed [11/11/1925 to 02/23/2023 – 97 yrs old], was a retired Allegheny Airlines Captain [US Airways]. He spent 13.5 years, 11,800 hours and 30162 take-offs & landings while flying the DC-3 in scheduled airline service for Lake Central Airlines [The FAA says it is a record for To's & Ldgs in a DC3 in domestic scheduled airline service], one of the legacy airlines of the "New American" Airlines.
Dad & Mom moved to Texas in 1977 from Catharpin, VA after my father retired from Allegheny Airlines [just before they changed their name to USAir in 1979 - he was originally with Lake Central Airlines - hire date 1953 - that merged with Allegheny in 1968] as a DC-9 Captain. He has flown in scheduled airline service the DC3, Nord 262, Convair 340 & 580 and the DC9-30 &-50. He was trained in the Army Air Corp during WWII on the P-47 & P-38. He never saw combat.

Developed for the United States Army Air Corps, the P-38 had distinctive twin booms and a central nacelle containing the cockpit and armament. Allied propaganda claimed it had been nicknamed the fork-tailed devil (German: der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto) by the Japanese.[6] The P-38 was used for interception, dive bombing, level bombing, ground attack, night fighting, photo reconnaissance, radar and visual pathfinding for bombers and evacuation missions,[7] and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the aircraft of America's top aces, Richard Bong (40 victories), Thomas McGuire (38 victories) and Charles H. MacDonald (27 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.[8][9]
The P-38 was unusually quiet for a fighter, since the exhaust was muffled by the turbo-superchargers. It was extremely forgiving and could be mishandled in many ways but the rate of roll in the early versions was too low for it to excel as a dogfighter.[10] The P-38 was the only American fighter aircraft in high-volume production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.[11] At the end of the war, orders for 1,887 more were cancelled.[12]

Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes,[15] the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed.[16] Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.

The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns with 200 rounds per gun (rpg), two .30-caliber (7.62 mm) Brownings with 500 rpg, and a T1 Army Ordnance 23 mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25 mm Hotchkiss aircraft autocannon specified by Kelsey and Saville.[18] In the YP-38s, a 37 mm (1.46 in) M9 autocannon with 15 rounds replaced the T1.[19] The 15 rounds were in three five-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20 mm (.79 in) autocannon with 150 rounds.[20]

A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas the wing guns of other fighters were optimized for a specific range.[21] The rate of fire was about 650 rounds per minute for the 20×110 mm cannon round (130-gram shell) at a muzzle velocity of about 2,850 ft/s (870 m/s), and for the .50-caliber machine guns (51-gram rounds), about 850 rpm at 2,900 ft/s (880 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20 mm shell.[22] The duration of sustained firing for the 20 mm cannon was approximately 14 seconds while the .50-caliber machine guns worked for 35 seconds if each magazine was fully loaded with 500 rounds, or for 21 seconds if 300 rounds were loaded to save weight for long distance flying.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000 hp (750 kW) turbosupercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the turbochargers positioned behind the engines, the exhaust side of the units exposed along the dorsal surfaces of the booms.[23] Counter-rotation was achieved by the use of "handed" engines, which meant the crankshaft of each engine turned in the opposite direction of its counterpart, a relatively easy task for a modular-design aircraft powerplant as the V-1710.
The P-38 was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels.[24] It was also the first military airplane to fly faster than 400 mph (640 km/h) in level flight.[25][26]

The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.

Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings and tail surfaces, lacking the slight sweepback of the Me 262. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kgf) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose. Some operational Kitsukas had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank. This markedly limited the aircraft’s range but was accepted for a dedicated trainer, but a ventral 500 l drop tank could be carried to extend the two-seater’s range to an acceptable level.
A small number, both single- and two-seaters, were furthermore adapted to night fighter duties and equipped with an experimental ”FD-2” centimeter waveband radar in the nose with an “antler” antenna array, similar to German radar sets of the time. The FD-2 used four forward-facing Yagi style antennae with initially five and later with seven elements (the sideway facing rods) each. These consisted of two pairs, each with a sending (top and bot) and a receiving antenna (left and right). The set used horizontal lobe switching to find the target, an electrical shifter would continuously switch between the sets. The signal strengths would then be compared to determine the range and azimuth of the target, and the results would then be shown on a CRT display.
In order to fit the electronics (the FD-2 weighed around 70 kg/155 lb) the night fighters typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style), which was mounted in the aircraft’s flank behind the cockpit, and the 500l drop tank became a permanent installation to extend loiter time, at the expense of top speed, though. These machines received the suffix “-S” and flew, despite the FD-2’s weaknesses and limitations, a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system. However, the FD-2’s performance was rather underwhelming, though, with an insufficient range of only 3 km. Increased drag due to the antennae and countermeasures deployed by B-29 further decreased the effectiveness, and the J9N2-S’s successes could be rather attributed to experienced and motivated crews than the primitive radar.
Proposed follow-on J9N versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ overall war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study. Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD. The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The kit and its assembly:
This is in fact the second Kikka I have built, and this time it’s a two-seater from AZ Models – actually the trainer boxing, but converted into a personal night fighter interpretation. The AZ Models kit is a simple affair, but that's also its problem. In the box things look quite good, detail level is on par with a classic Matchbox kit. But unlike a Matchbox kit, the AZ Models offering does not go together well. I had to fight everywhere with poor fit, lack of locator pins, ejection marks - anything a short run model kit can throw at you! Thanks to the experience with the single-seater kit some time ago, things did not become too traumatic, but it’s still not a kit for beginners. What worked surprisingly well was the IP canopy, though, which I cut into five sections for an optional open display – even though I am not certain if the kit’s designers had put some brain into their work because the canopy’s segmentation becomes more and more dubious the further you go backwards.
The only personal mods is a slightly changed armament, with one nose gun deleted and faired over with a piece of styrene sheet, while the leftover gun was mounted obliquely onto the left flank. I initially considered a position behind the canopy but rejected this because of CoG reasons. Then I planned to mount it directly behind the 2nd seat, so that the barrel would protrude through the canopy, but this appeared unrealistic because the (utterly tiny) sliding canopy for the rear crewman could not have been opened anymore? Finally, I settled for an offset position in the aircraft’s flanks, partly inspired by “Schräge Musik” arrangements on some German Fw 190 night fighters.
The antennae come from a Jadar Model PE set for Italeri’s Me 210s, turning it either into a night fighter or a naval surveillance aircraft.
Painting and markings:
This became rather lusterless; many late IJN night fighters carried a uniform dark green livery with minimalistic, toned-down markings, e. g. hinomaru without a white high-contrast edge, just the yellow ID bands on the wings’ leading edges were retained.
For this look the model received an overall basis coat of Humbrol 75 (Bronze Green), later treated with a black ink washing, dry-brushed aluminum and post-shading with lighter shades of dark green (including Humbrol 116 and Revell 67). The only colorful highlight is a red fin tip (Humbrol 19) and a thin red stripe underneath (decal). The yellow and white ID bands were created with decal material.
The cockpit interior was painted in a yellowish-green primer (trying to simulate a typical “bamboo” shade that was used in some late-war IJN cockpits), while the landing gear wells were painted in aodake iro, a clear bluish protective lacquer. The landing gear struts themselves became semi-matt black.
The markings are fictional and were puzzled together from various sources. The hinomaru came from the AZ Models’ Kikka single seater sheet (since it offers six roundels w/o white edge), the tactical code on the fin was created with red numbers from a Fujimi Aichi B7A2 Ryusei.
Finally, the kit received a coat of matt acrylic varnish and some grinded graphite around the jet exhausts and the gun nozzles.
Well, this fictional Kikka night fighter looks quite dry, but that makes it IMHO more credible. The large antler antenna array might look “a bit too much”, and a real night fighter probably had a simpler arrangement with a single Yagi-style/arrow-shaped antenna, but a description of the FD-2 radar suggested the layout I chose – and it does not look bad. The oblique cannon in the flank is another odd detail, but it is not unplausible. However, with all the equipment and esp. the draggy antennae on board, the Kikka’s mediocre performance would surely have seriously suffered, probably beyond an effective use. But this is whifworld, after all. ;-)
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).

Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.
For example, the low-price Champion had arrived in spring 1939 with a lightweight L-head six of 164.3 cubic inches. This went to 169.6 cubic inches and 80 horsepower for 1941-49, then added five horsepower. The costlier Commanders used a larger six dating from Studebaker's 1932 Rockne. By 1949, this engine was up to 245.6 cubic inches and 100 horsepower.
The 1947-1949 models were a great sales success, lifting Studebaker to eighth in the U.S. industry with a market share of 4.12 percent. Production was at record levels. So were corporate profits -- $27.56 million in calendar 1949 alone. Things looked great, and were about to get even better.
The bullet-nose idea had been on Bourke's drawing board since 1940-1941, when he first sketched several elements of the eventual 1950 Studebaker. Chief among them was a protruding nose with flanking pontoon fenders suggesting the front of an airplane.
Public reaction is what matters in the auto industry, and "The Next Look" 1950 Studebaker, featuring the company's signature "bullet-nose" look for the first time, was a winner -- more popular than even the 1947. Sales began in August 1949, nearly a month ahead of other 1950 cars.
For all this hoopla, the 1950s were identical to the 1947-49 models except for the bullet nose, minor trim, and vertical instead of horizontal taillights. However, the new front end added an inch to wheelbases, taking Champions to 113, Commanders to 120. Both lines again offered two- and four-door sedans, a convertible, and a five-passenger Starlight coupe with its distinctive panoramic rear window.
Demand for the bullet-nose '50s proved so strong that Studebaker added a third shift at its large South Bend factory and ran its Southern California and Hamilton, Ontario, assembly plants at or near capacity. A 14-month model "year" (July 15, 1949, to September 27, 1950) produced 343,164 cars -- the most for any vehicle in Studebaker's long history. By the end of 1950, company employment was up to 25,000, a peacetime record.

The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.
For example, the low-price Champion had arrived in spring 1939 with a lightweight L-head six of 164.3 cubic inches.

Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.

Some Background:
The Ki-38 fighter was designed by the Tachikawa Aircraft Company Limited (立川飛行機株式会社, Tachikawa Hikōki Kabushiki Kaisha) near Tokyo, an aircraft manufacturer in the Empire of Japan, specializing primarily in aircraft for the Imperial Japanese Army Air Force. The Ki-38 prototype was produced in response to a December 1937 specification for a successor to the popular fixed-gear Nakajima Ki-27 Nate. The specification called for a top speed of 500 km/h (310 mph), a climb rate of 5,000 m (16,000 ft) in five minutes and a range of 800 km (500 mi). Maneuverability was to be at least as good as that of Ki-27.
When first flown in early January 1939, the Ki-38 prototype was a disappointment. Japanese test pilots complained that it was less maneuverable than the Ki-27 Nate and not much faster. Even though the competition was eventually won by the Ki-43, service trials determined the aircraft to hold sufficient promise to warrant further work, leading to the adoption of an expanded and strengthened wing and a more refined Mitsubishi Ha-102 (Army Type 100 1,050hp Air Cooled Radial) 14-cylinder air-cooled radial piston engine. During spring 1939, following the completion of further proving trials, an order for a pre-production batch of 25 aircraft was placed.
As a whole, the Ki-38 was an all-modern design consisting of all-metal skin and understructure construction with low-set monoplane wing appendages. The wings were straight in their general design with rounded tips and set well-forward of amidships. The engine was fitted to the extreme forward section of the fuselage in a traditional manner, powering a three-bladed propeller installation. Interestingly, the cockpit was also situated well-forward in the design, shortening the visual obstacle that was the engine compartment to some extent. However, views were still obstructed by the short engine housing to the front and the wings to the lower sides. The fuselage tapered at the rear to which a single vertical tail fin was affixed along with mid-mounted horizontal tailplanes. The undercarriage was retractable and of the "tail-dragger" arrangement consisting of two main single-wheeled landing gear legs and a fixed, diminutive tail wheel leg at the rear.
The series-production Ki-38-I was further modified to enhance its performance. These changes involved a major weight saving program, a slimmer and longer fuselage with bigger tail surfaces and a new, more streamlined bubble-style canopy that offered, even while bearing many struts, the pilot a very good all-round field of view.
In addition to good maneuverability, the Ki-38-I had a good top speed of more than 500 km/h (310 mph). The initial Ki-38 was armed with four 7.7 mm (0.303 in) Type 89 machine guns in the wings, but this soon turned out to be insufficient against armored Allied fighters and bombers. Quickly, the inner pair of weapons was, after just 50 aircraft, replaced with 12.7 mm (0.50 in) Ho-103 machine guns in the Ki-38-Ib (the initial version subsequently became the Ki-38-Ia), of which 75 were built. On board of the following Ki-38-Ic, the inner weapons were replaced with a pair of even heavier and more effective 20 mm (0.787 in) Ho-5 cannon, which required fairings for the ammunition under the wings and made this version easy to identify. The Ki-38-Ic became the most frequent variant, with 150 examples built.
All types also featured external hardpoints for a drop tank under the fuselage or a pair of bombs of up to 250 kg (550 lb) caliber under the wings. Late production aircraft were designated Ki-38-II. The pilot enjoyed a slightly taller canopy and a reflector gunsight in place of the earlier telescopic gunsight. The revised machines were also fitted with a 13 mm (0.51 in) armor plate for the pilot's head and back, and the aircraft's fuel tanks were coated in rubber to form a crude self-sealing tank. This was later replaced by a 3-layer rubber bladder, 8mm core construction, with 2mm oil-proof lamination. Some earlier aircraft were retrofitted with these elements, when available to the field workshops, and they dramatically improved the aircraft’s resilience to enemy fire. However, the bladder proved to be highly resistant only against light 7.7 mm (0.303 in) bullets but was not as effective against larger calibers. The Ki-38-II’s armament was the same as the Ki-38-Ic’s and 120 aircraft were built.
Ki-38 production started in November 1939 at the Tachikawa Hikoki KK and at the 1st Army Air Arsenal (Tachikawa Dai-Ichi Rikugun Kokusho) plants, also at Tachikawa. Although Tachikawa Hikoki successfully managed to enter into large-scale production of the Ki-38, the 1st Army Air Arsenal was less successful – hampered by a shortage of skilled workers, it was ordered to stop production after 49 Ki-38 were built, and Tachikawa ceased production of the Ki-38 altogether in favor of the Ki-43 in mid-1944.
Once it was identified and successfully distinguished from the IJA’s new Ki-43 “Oscar” and the IJN’s A6M “Zero” (Oscar), which both had very similar outlines, the Ki-38 received the Allied code name “Brad”. Even though it was not produced in the numbers of the Ki-43 or the A6M, the Ki-38 fought in China, Burma, the Malay Peninsula, New Guinea, the Philippines, South Pacific islands and the Japanese home islands. Like the Oscar and the Zero, the Ki-38 initially enjoyed air superiority in the skies of Malaya, Netherlands East Indies, Burma and New Guinea. This was partly due to the better performance of the Brad and partly due to the relatively small numbers of combat-ready Allied fighters, mostly the Curtiss P-36 Hawk, Curtiss P-40, Brewster Buffalo, Hawker Hurricane and Curtiss-Wright CW-21 in Asia and the Pacific during the first months of the war.
As the war progressed, however, the fighter suffered from the same weaknesses as its slower, fixed-gear Ki-27 "Nate" predecessor and the more advanced naval A6M Zero: light armor and less-than-effective self-sealing fuel tanks, which caused high casualties in combat. Its armament of four light machine guns also proved inadequate against the more heavily armored Allied aircraft. Both issues were more or less mended with improved versions, but the Ki-38 could never keep up with the enemy fighters’ development and potential. And as newer Allied aircraft were introduced, the Japanese were forced into a defensive war and most aircraft were flown by inexperienced pilots.

The kit and its assembly:
I always thought that the French Bloch MB 150 had some early WWII Japanese look to it, and with this idea I recently procured a relatively cheap Heller kit for this conversion project that would yield the purely fictional Tachikawa Ki-38 for the IJA – even though the Ki-38 existed as a Kawasaki project and eventually became the Ki-45, so that the 38 as kitai number was never actively used.
The Heller MB 150 is a vintage kit, and it is not a good one. You get raised panel lines, poor details (the engine is a joke) and mediocre fit. If you want a good MB 150 in 1:72, look IMHO elsewhere.
For the Ki-38 I wanted to retain most of the hull, the first basic change was the integration of a cowling from a Japanese Mitsubishi Ha-102 two-row radial (left over from an Airfix Ki-46 “Dinah”), which also received a new three-blade propeller with a different spinner on a metal axis inside. The engine also received some more interior details, even though the spinner blocks most sight.
The next, more radical move was to replace the MB 150’s spinal cockpit fairing with a bubble canopy and a lowered back – I found a very old and glue-tinted canopy from a Matchbox A6M in the spares box, and it turned out to be very suitable for the Ki-38. However, cleaning the clear piece was quite challenging, because all raised struts had to be sanded away to get rid of the old glue and paint residues, and re-polishing it back to a more or less translucent state took several turns with ever finer sandpaper, polishing paste and soft polishing mops on a mini drill. The spine was re-created with 2C-putty and the canopy was blended into it and into the fuselage with several PSR turns.
Inside, I used a different pilot figure (which would later be hard to see, though), added a fuel tank behind the seat with some supporting struts and inserted a piece of styrene sheet to separate the landing gear well from the cockpit – OOB it’s simply open.
The landing gear was basically taken OOB, I just replaced the original tail skid with a wheel and modified the wheels with hub covers, because the old kit wants you to push them onto long axis’ with knobs at their tips so that they remain turnable. Meh!
The fairings under the guns in the wings (barrels scratched from the MB 150’s OOB parts) are conformal underwing fuel tanks from a late Seafire (Special Hobby kit).
Painting and markings:
The initial plan was a simple green/grey IJA livery, but the model looked SO much like an A6M that I rather decided to give it a more elaborate paint scheme. I eventually found an interesting camouflage on a Mitsubishi Ki-51 “Sonia” attack plane, even though without indications concerning its unit, time frame or theater of operations (even though I assume that it was used in the China-Burma-India theater): an overall light grey base, onto which opaque green contrast fields/stripes had been added, and the remaining light grey upper areas were overpainted with thin sinuous lines of the same green. This was adapted onto the Ki-38 with a basis in Humbrol 167 (RAF Barley Grey) and FS 34102 (Humbrol 117) for the green cammo. I also wanted to weather the model considerably, as a measure to hide some hardware flaws, so that a partial “primer coat” with Aluminum (Revell 99) was added to several areas, to shine through later. The yellow ID markings on the wings’ leading edges were painted with Humbrol 69. The propeller blades were painted with Humbrol 180, the spinner in a slightly lighter mix of 180 and 160.
Interior surfaces were painted with a dull yellowish green, a mix of Revell 16 and 42, just the inside of the landing gear covers became grey as the outside, in a fashion very similar to early Ki-43s.
The decals came form various sources, including a Hasegawa Ki-61 sheet for the unit markings and some stencils and hinomaru in suitable sizes from a generic roundel sheet.
Some dry-brushing with light grey was done to emphasize edges and details, and some soot stains were added with graphite to the exhausts and the guns. Finally, the kit was sealed with matt acrylic varnish, some more dry-brushing with aluminum was done, esp. around the cockpit, and position lights were added with translucent paint.
An unexpected result – I was not prepared that the modified MB 150 looks THAT much like a Mitsubishi A6M or the Ki-43! There’s even an Fw 190-ish feel to it, from certain angles. O.K., the canopy actually comes from a Zero and the cowling looks very similar, too. But the overall similarity is baffling, just the tail is the most distinguishing feature! However, due to the poor basis and the almost blind canopy donor, the model is far from stellar or presentable – but some in-flight shots look pretty convincing, and even the camouflage appears to be quite effective over wooded terrain.

Some background:
The Yokosuka J1Y was a land-based interceptor for the Imperial Japanese Navy Air Service (IJN/大日本帝國海軍航空隊, Dai-Nippon Teikoku Kaigun Kōkū-tai) that was based upon a research aircraft and introduced into service during the final months of WWII. Work on the J1Y commenced at the Yokosuka Naval Air Technical Arsenal (海軍航空技術廠, Kaigun Kōkū Gijutsu-shō) during 1942 and 1943, in the midst of the Second World War. The J1Y was initially intended to test the benefits of different aircraft layouts in order to exploit the available engines’ potential further, albeit the aircraft had been designed from the start in a fashion that was suitable for combat and easily adaptable into a light fighter aircraft. It would eventually be developed into Yokusuka’s only fighter project.
The J1Y was an unorthodox twin-boom pusher configuration fighter aircraft. It featured a mid-mounted wing, a tricycle landing gear arrangement, and was furnished with heavy forward-firing armament. The fuselage was primarily composed of plywood for the forward section and aluminum throughout the aft section, in order to save critical war material. The advantages of the pusher design were of an unobstructed forward view for the pilot, while the armament could also be concentrated in the nose, so that most of the aircraft’s heavy elements were concentrated around the mutual center of gravity. However, a major drawback was difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades, and the tail surfaces posed an imminent danger, too.
The J1Y1 test aircraft was powered by a 700 kW (940 hp) Nakajima Sakae 12 engine. A pair of intakes in the wings’ roots ducted cooling air to the engine, which was mounted at the egg-shaped fuselage’s tail, as well as to a pair of oil coolers that were buried in the thickened wing roots. Despite the aircraft’s tubby shape, it was a very clean design with an excellent weight distribution.
During the ensuing tests and flight trials in late 1943, the J1Y1 proved to be superior to the comparable Mitsubishi A6M2 “Zero” in many respects, so that the Imperial Japanese Navy Aviation Bureau (海軍航空本部, Kaigun Kōkū Hombu) became interested enough to eventually order a fully capable combat aircraft variant in early 1944: the J1Y2.
Development of the J1Y2 lasted until mid-1944. Outwardly, the aircraft differed only slightly from the J1Y1 test aircraft, of which four had been built. The internal structure was strengthened, esp. around the engine mount, because the fighter version was to be powered by the Mitsubishi Kinsei Model 48 radial engine which delivered 1,080 hp (810 kW). Since this engine had a slightly bigger diameter, the tight cowling had to be modified and now featured small bulges for its fourteen-cylinder heads, creating a characteristic ring of small bumps around the rear fuselage. The dorsal carburetor air scoop had to be enlarged, too.
The J1Y1’s four-blade propeller was replaced by a six-blade propeller – a measure that was necessary to convert the engine’s raised power output into sufficient propulsion, while exploiting the limited possible propeller disc diameter between the tail booms and keeping sufficient ground clearance.
Armor plates were added to the nose section and behind the pilot’s seat, but protection remained relatively light. In order to extend the J1Y1’s limited range of only 750 km (470 mi, 400 nmi), two additional 150l fuel tanks were added to the inner wings behind the landing gear wells, partly extending into the tail booms, even though they were not self-sealing like the main fuel tank behind the cockpit. Tilting air brakes were installed on the wings, enabling the J1Y1 to manoeuvre into a stable firing position behind slower aircraft. Armament consisted of a pair of 20 mm Type 99-2 cannon, flanking the front wheel well, supplemented by a pair of 7.7 mm (.303 in) Type 97 machine guns, which were rather intended as spotting rifles: they fired tracer rounds with the same trajectory as the 20 mm rounds, and gave off a flash and puff of white smoke on impact, so that 20 mm ammunition could be saved. Upon IJN introduction in August 1944, the J1Y was christened “Akaei” (アカエイ, “Stingray”). The Allied reporting name was "Ron"
However, teething development problems stemming from the Kasei engine cooling system and the main undercarriage members led to a slowdown in production. And when the Boeing B-29 Superfortress appeared, the J1Y2’s performance, esp. at height, was not sufficient anymore. Being not suited for high-altitude operations, and lacking internal space to accommodate a turbocharger, the IJN’s interest in the aircraft waned and resources were rather allocated to more promising types like the Mitsubishi J2M, despite its development problems, too. However, the J1Y2’s heavy gun armament supplied effective firepower and the use of dive and zoom tactics allowed it to score occasionally. It was also a very agile aircraft, esp. at medium altitude, so that production switched in January 1945, after 75 J1Y2s had been built, to the J1Y3.
The ultimate variant of the “Akaei” featured a new, even more powerful Mitsubishi Kinsei 62 engine with 1,163 kW (1,560 hp). Outwardly, this variant differed from its predecessor by a different exhaust arrangement: instead of the J1Y2’s two exhaust pipes, the J1Y3 featured individual exhaust, hidden under seven aerodynamic fairings, in order to exploit residual thrust and therefore further improve performance – resulting in even more bumps and fairing around the engine cowling. For the more powerful engine, and also because of cooling problems, the carburetor scoop was enlarged even more, so that an auxiliary cooling intake could be integrated.
Even though the armament nominally remained unchanged, supply shortages and field modifications in order to lighten the aircraft saw many J1Y3s with only two Type 99 cannons installed and the empty machine gun ports faired over. Some J1Y3s also carried gun 13.2 mm (.51 in) Type 3 heavy machine guns instead of the cannons, becoming designated J1Y3a. Due to ammunition shortages, some machines were converted in field workshops to this standard, too.
The J1Y3 arrived at IJN units in March 1945, but only a few were operational until the end of hostilities in the PTO, probably only around 40 aircraft were eventually delivered.

The kit and its assembly:
This build followed a spontaneous inspiration, and it became another contribution to the “in the navy” group build at whatifmodlers.com in early 2020. I actually had the Vampire kit already stashed away for a while, and the plan to convert it into a propeller-driven aircraft with a radial engine and a pusher configuration à la Saab 21 had been there – but I lacked an idea for an operator, so that I could build the background story around it. With the “in the navy” theme, it suddenly clicked – why not the IJN? The Vampire is a rather compact and slender aircraft, so there’s IMHO some Japanese “style” in the design, and after the torturous build of HMS Cerberus I wanted some kind of relief.
The Vampire kit is the vintage Heller mold from 1979, but actually in a mid-Nineties Revell re-boxing. Like many other Heller kits, it comes with raised panels, but detail is sufficient (nice dashboard, landing gear is O.K., and the kit comes with separate air brakes) – the molds seem to be a bit worn, though, I guess a “true” old Heller kit is more crisp and would be the better choice.
At the core of the conversion plan was the implantation of a radial engine in place of the jet exhaust. I found a donor part from a Hobby Boss MC.200 Saetta – a bit vintage, but it had the right diameter and I actually liked the ring of bulges on the cowling. Internally, a styrene tube adapter was added for a freely spinning propeller.
While adding a prop to a jet seems to be an easy task, the real challenge behind such a conversion are the many other changes that have to be made to the airframe. This includes a (considerably) longer landing gear and the respective wells, but also the tail surfaces. There’s also the question how the new radial engine actually breathes, where exhausts can be located, and a cooling system is necessary, too.
Work started with the search for new landing gear struts, and I also used different wheels – for instance, the main wheels come from a Hasegawa F9F Panther, while the front wheel comes from a Frog He 162 and is probably 35 years old(!). In order to make the longer struts fit into the airframe, I elongated the wells in the wings towards the fuselage, so that the track width was reduced – but with the Vampire’s small airframe and original wide stance, this was no serious problem. From the inside, they were faired with styrene profile material, and the extended covers were scratched – esp. the parts for the wings, with their bulges for the tail boom tips, were fiddly.
In order to move the overall look a bit further away from the Vampire, I completely changed the fin arrangement. The original, rounded and rather small fins and the bullet-shaped fairings that hold the stabilizer outside of the original exhaust blast were deleted. Once the wings and the tail booms were added to the fuselage, the stabilizer was mounted between the booms, in a slightly lower position. For the new fins I wanted a layout that would, beyond a more squarish shape that would better match the wings, protect the propeller. Therefore, I used stabilizers from a KP Yak-23; each was cut into two pieces, tailored further to match the rest of the aircraft, and glued in positions above and underneath the booms. Looks quite weird, as if the aircraft had been designed upside down, but it’s a rather pragmatic solution that has already been used on some pusher designs in the past.
The six-blade propeller was scratched from a spinner, carved from a thick piece of sprue, plus a metal axis and six single blades that were taken from the rather wacky one-piece propellers of Airfix’s Ki-46 kit.
Hollow steel needles were used as barrels for the Type 99 cannons in the lower fuselage.
Painting and markings:
Once more, a rather conservative approach – and the IJN was not creative when it came to liveries. Almost every aircraft carried a typical dark green over light grey scheme, with minimal individual markings or tactical codes. I wanted to stay true to this concept but decided to simplify the scheme even more since this would be a late-war aircraft, pressed into service under rather dire supply circumstances. This resulted in a NMF livery (basis is Tamiya XF-60, which turned out soemwaht grainy, plus some Polished Aluminum Metallizer from Humbrol on top), with only the upper surfaces camouflaged with IJN Green (ModelMaster) without primer underneath, resulting in a somewhat flaky and worn look. Since they are rather slender, the tail booms were completely painted in IJN green, too.
The yellow ID markings on the wings’ leading edges were created with decal material (TL Modellbau), the cockpit interior as well as the landing gear wells were painted with a mix of silver and blue, mimicking the typical “aodake iro” protective clear lacquer of Japanese IJN aircraft. The struts were painted black, according to A6M museum exhibits. The propeller blades ware painted in a red-brown primer, a mix of Humbrol 160 and 180.
Markings were taken from a PrintScale Yokosuka N1K2 decal sheet and mixed from two aircraft. Placing the fuselage hinomaru was tricky – the natural choice would have been the tail booms, but they’d be very small, so I rather put them on the fuselage under the cockpit. With the individual aircraft number added to the meatball, it looks now like a racing aircraft, though...
Finally, the kit received some soot stains and dry-brushing with aluminum, and everything was sealed with semi-gloss acrylic varnish from Italeri - even though the result is a little too glossy for my taste, but I left it that way.
A rather quick build, but structurally not much from the Vampire was changed. The new engine was relatievly easy to integrate - the other small bits like the fins, the propeller and esp. the landing gear took more time. The result looks quite odd - the whole thing has also a certain German touch? Could have worked well with a BMW 801 engine, too!

Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings and tail surfaces, lacking the slight sweepback of the Me 262. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kgf) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose. Some operational Kitsukas had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank. This markedly limited the aircraft’s range but was accepted for a dedicated trainer, but a ventral 500 l drop tank could be carried to extend the two-seater’s range to an acceptable level.
A small number, both single- and two-seaters, were furthermore adapted to night fighter duties and equipped with an experimental ”FD-2” centimeter waveband radar in the nose with an “antler” antenna array, similar to German radar sets of the time. The FD-2 used four forward-facing Yagi style antennae with initially five and later with seven elements (the sideway facing rods) each. These consisted of two pairs, each with a sending (top and bot) and a receiving antenna (left and right). The set used horizontal lobe switching to find the target, an electrical shifter would continuously switch between the sets. The signal strengths would then be compared to determine the range and azimuth of the target, and the results would then be shown on a CRT display.
In order to fit the electronics (the FD-2 weighed around 70 kg/155 lb) the night fighters typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style), which was mounted in the aircraft’s flank behind the cockpit, and the 500l drop tank became a permanent installation to extend loiter time, at the expense of top speed, though. These machines received the suffix “-S” and flew, despite the FD-2’s weaknesses and limitations, a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system. However, the FD-2’s performance was rather underwhelming, though, with an insufficient range of only 3 km. Increased drag due to the antennae and countermeasures deployed by B-29 further decreased the effectiveness, and the J9N2-S’s successes could be rather attributed to experienced and motivated crews than the primitive radar.
Proposed follow-on J9N versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ overall war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study. Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD. The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The kit and its assembly:
This is in fact the second Kikka I have built, and this time it’s a two-seater from AZ Models – actually the trainer boxing, but converted into a personal night fighter interpretation. The AZ Models kit is a simple affair, but that's also its problem. In the box things look quite good, detail level is on par with a classic Matchbox kit. But unlike a Matchbox kit, the AZ Models offering does not go together well. I had to fight everywhere with poor fit, lack of locator pins, ejection marks - anything a short run model kit can throw at you! Thanks to the experience with the single-seater kit some time ago, things did not become too traumatic, but it’s still not a kit for beginners. What worked surprisingly well was the IP canopy, though, which I cut into five sections for an optional open display – even though I am not certain if the kit’s designers had put some brain into their work because the canopy’s segmentation becomes more and more dubious the further you go backwards.
The only personal mods is a slightly changed armament, with one nose gun deleted and faired over with a piece of styrene sheet, while the leftover gun was mounted obliquely onto the left flank. I initially considered a position behind the canopy but rejected this because of CoG reasons. Then I planned to mount it directly behind the 2nd seat, so that the barrel would protrude through the canopy, but this appeared unrealistic because the (utterly tiny) sliding canopy for the rear crewman could not have been opened anymore? Finally, I settled for an offset position in the aircraft’s flanks, partly inspired by “Schräge Musik” arrangements on some German Fw 190 night fighters.
The antennae come from a Jadar Model PE set for Italeri’s Me 210s, turning it either into a night fighter or a naval surveillance aircraft.
Painting and markings:
This became rather lusterless; many late IJN night fighters carried a uniform dark green livery with minimalistic, toned-down markings, e. g. hinomaru without a white high-contrast edge, just the yellow ID bands on the wings’ leading edges were retained.
For this look the model received an overall basis coat of Humbrol 75 (Bronze Green), later treated with a black ink washing, dry-brushed aluminum and post-shading with lighter shades of dark green (including Humbrol 116 and Revell 67). The only colorful highlight is a red fin tip (Humbrol 19) and a thin red stripe underneath (decal). The yellow and white ID bands were created with decal material.
The cockpit interior was painted in a yellowish-green primer (trying to simulate a typical “bamboo” shade that was used in some late-war IJN cockpits), while the landing gear wells were painted in aodake iro, a clear bluish protective lacquer. The landing gear struts themselves became semi-matt black.
The markings are fictional and were puzzled together from various sources. The hinomaru came from the AZ Models’ Kikka single seater sheet (since it offers six roundels w/o white edge), the tactical code on the fin was created with red numbers from a Fujimi Aichi B7A2 Ryusei.
Finally, the kit received a coat of matt acrylic varnish and some grinded graphite around the jet exhausts and the gun nozzles.
Well, this fictional Kikka night fighter looks quite dry, but that makes it IMHO more credible. The large antler antenna array might look “a bit too much”, and a real night fighter probably had a simpler arrangement with a single Yagi-style/arrow-shaped antenna, but a description of the FD-2 radar suggested the layout I chose – and it does not look bad. The oblique cannon in the flank is another odd detail, but it is not unplausible. However, with all the equipment and esp. the draggy antennae on board, the Kikka’s mediocre performance would surely have seriously suffered, probably beyond an effective use. But this is whifworld, after all. ;-)
New pics of an old kit, but one I hold pretty dear: because it was an accidental find (and never expected that such official merchandise existed at all!) and because I like (if not love) the manga where it comes from and in which the J7W has a brief appearance in one of the series' early stories.
I found this Hasegawa kit in a model kit shop for Japanese animation in Berlin, in a dark shop corner.
The kit itself is the standard 1:72 Hasegawa scale model of the WWII Shinden prototype. New water sliding decals and painting instructions were included, and the kit has been mostly built "out of the box".
The "paradigm" for this machine, which is supposed to be the (fictional) second Shinden prototyp which had been buried before the American invasion and lost, stems from a special edition of the "Oh, my goddess" manga, a one-shot story during the first or second series of books called "On a Wing and a Prayer", around 1997.
Actually, I was a bit suprised by the kit's colors, since the manga mentions a "green fuselage" - but this could also have been a translation error. Bit it is not: later I found out that "green" and "blue" use the same word in Japanese, so the confusion comes from the outsiders' point fo view. ;)
Hasegawa recommends white and a dark petrol blue, which is a non-standard color and has to be mixed manually. Other weird color details include the brown propeller (O.K., it's IJN primer, but looks pretty weird in the overall combo!) and the bright red landing gear insides... but since there are no other color references available (the manga is B/W), I stuck with Hasegawa's official instructions.
The kit itself is of high quality (typical Hasegawa standard) and the parts fit well.
The tricky job is the painting, though, with lots of white and the very complicated blue contrast areas with hard and straight demarcation lines, which are especially hard to paint on the fuselage, because of the air intake bulgings. I did not get it as good as I wanted to...
Another tricky part are the decals for some of the blue areas. While the idea of having some of the delicate shapes as a water decal at hand, matching the color of the printed decals and the rest of the paint is another task - you will recognize some areas with color differences ;)
Besides these troubles, some details in the cockpit and at the landing gear were added - overall a very good kit, but due to the delicate color scheme nothing for beginners or those faint at heart!
As a side note: In the meantime (well, many years have passed since I built this one), there's an 1:32 OOB offering of this specific bird from literature available, from Zoukei Moura. Funny to see that the company chose a much brighter blue, and it differs in some other details (e .g. having a white canopy framing), too.

Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings and tail surfaces, lacking the slight sweepback of the Me 262. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kgf) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose. Some operational Kitsukas had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank. This markedly limited the aircraft’s range but was accepted for a dedicated trainer, but a ventral 500 l drop tank could be carried to extend the two-seater’s range to an acceptable level.
A small number, both single- and two-seaters, were furthermore adapted to night fighter duties and equipped with an experimental ”FD-2” centimeter waveband radar in the nose with an “antler” antenna array, similar to German radar sets of the time. The FD-2 used four forward-facing Yagi style antennae with initially five and later with seven elements (the sideway facing rods) each. These consisted of two pairs, each with a sending (top and bot) and a receiving antenna (left and right). The set used horizontal lobe switching to find the target, an electrical shifter would continuously switch between the sets. The signal strengths would then be compared to determine the range and azimuth of the target, and the results would then be shown on a CRT display.
In order to fit the electronics (the FD-2 weighed around 70 kg/155 lb) the night fighters typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style), which was mounted in the aircraft’s flank behind the cockpit, and the 500l drop tank became a permanent installation to extend loiter time, at the expense of top speed, though. These machines received the suffix “-S” and flew, despite the FD-2’s weaknesses and limitations, a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system. However, the FD-2’s performance was rather underwhelming, though, with an insufficient range of only 3 km. Increased drag due to the antennae and countermeasures deployed by B-29 further decreased the effectiveness, and the J9N2-S’s successes could be rather attributed to experienced and motivated crews than the primitive radar.
Proposed follow-on J9N versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker".

The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.

1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

Some background
The history of Focke Wulf's Fw 190 in Japan started with a rejection: in 1943 a single FW 190 A-5 had been supplied to Japan for evaluation, but at first, the type was not put into production by the Japanese. Anyway, the results of the study by Japanese engineers were incorporated in the design of the Ki-61 fighter. This evaluation did not go unnoticed, since the type received the Allied code-name 'Fred'.
By that time, the teething development problems of Mitubishi's J2M ‘Raiden’ (Thunderbolt) 'Jack' led to a slowdown in production. Biggest issues were the Kasei engine, an unreliable propeller pitch change mechanism and the main undercarriage members. Another drawback of the type was that its design put emphasis on performance and pilot protection rather than maneuverability. By the time the Fw 190 was tested, only fourteen J2M had been completed.
To make matters even worse, the Mitsubishi A7M 'Reppu' fighter was also behind schedule, so that replacements for the A6M 'Zero', backbone of the IJN’s air force, were overdue.
This situation left the Imperial Japanese Navy without a land-based interceptor. The first few produced J2M2 were delivered to the development units in December 1942 but further trials and improvements took almost a year, and it took until June 1944 that the ‘Raiden’ could make its combat debut, during the Battle of the Philippine Sea.
While the Raiden was to be developed further for the high-altitude interceptor role, the IJN decided in January 1944 to adopt the highly effective Fw 190 as a supplementary interceptor for medium heights - only as a stop-gap at first, but the type quickly evolved into various sub-variants, much like in Germany.
License production of the adopted Fw 190 started at Hitachi in May 1944. The original airframe was modified to cater to Japanese needs and customs, and the most obvious difference of the J10F1, how the plane was officially called, was the use of the Mitsubishi MK4R Kasei 23c radial engine instead of the original BMW 801. It was a modified version of the engine in the J2M, but simplified and made more reliable. The engine produced 1.820hp and drove a four-bladed propeller. Another distinctive feature was a small fin fillet, which compensated directional instability due to the longer forward fuselage.
By its pilots, the J10F quickly became called “hueruge” (フエルゲル), a transcription of the Fw 190's German nickname "Würger" (=Shrike).
Variants:
J10F1
The original main variant with the MK4R Kasei 23e and armed with 2× 13.2 mm Type 3 machine guns and 4× 20 mm two Type 99 Model 2 cannons, 354 aircraft produced.
While no official sub-variant was developed or designated, single machines differed considerably in equipment. This included field-modifications like reduced armament for better performance or ground-attack equipment, e .g. racks for a total of four unguided 60kg air-to-air missiles under the outer wings.
J10F1-G
In late 1945 a few J10F1 were modified for the anti-ship role and night attacks, and they received the "-G" suffix for their new land-based bomber role. These planes had a reduced gun armament, flame dampers and an IR sight, similar to the German “Spanner” device.
Most of these planes were to carry special weapons, like a single indigenous Ke-Go 110 heat-seeking guided bomb under the belly, or, alternatively, a copy of the German Bv 246 "Hagelkorn" gliding bomb, which had been delivered to Japan in 1944 for tests and adopted for production. To allow more space under the fuselage while carrying these bombs on the ground, some of these aircraft had a longer tail wheel strut fitted. Additionally, tests were made with a torpedo on the centerline hardpoint. It is uncertain if these weapons were actually used in combat, though.
J10F2
The only variant that was developed so far that it entered service, incorporating many detail modifications and improvements. These included thicker armored glass in the cabin's windshield (from 5.5 cm/2.2” to 7.6cm/3”) and extra armor plating behind the pilot's seat. The wing skinning was thickened in localized areas to allow for a further increase in dive speed. A water-methanol engine boost was added, which allowed an engine output of 2.050 hp for short periods, which boosted the top speed to 695 km/h. 52 were produced.
J10F3
High altitude project with a pressurized cabin, a larger wing span of 11.96 m (39 ft 2 in) and a turbo-supercharged MK4R-C Kasei 23c engine, with the turbo-supercharger mounted behind the cockpit (itself made wider). This doubled the altitude at which the engine could produce its rated power, from 15,750ft up to 30,185ft. The J10F3 only carried two 20mm cannons in the wing roots, but had two extra oblique-firing 20mm cannon installed aft of the cockpit for use against high flying American B-29 bombers (much like the German "Schräge Musik" installments). Two prototypes were completed in June 1945, but the turbo-supercharger proved troublesome, and no further aircraft of this type were produced.
From late 1944 on, the J10F1 was quickly thrown into service and became a nasty surprise for Allied aircraft. The modified Focke Wulf design proved to be agile, fast and much tougher than earlier Japanese fighters, coupled with a relatively heavy armament. Beyond interception duties, the J10F1 was frequently employed in close support and anti-shipping tasks, since its low level handling and ordnance load was excellent.
Its only drawback was - as with the original Fw 190 - that performance dropped at heights above 6.000m. This should not have posed a problem with the J2M, but that type's delay left the Allied high-altitude bomber attacks relatively unharmed, so that the J10F3 version was hastily developed, but failed to realize. In Germany, the similar situation resulted in the Fw 190 D-9 variant and finally in the superb Ta-152.

The kit and its assembly
The 'Japanese Fw 190' is a popular what-if topic, so I wanted to add my interpretation to the plethora of whifs and replicas of the real test machine. Actually, a clean Fw 190 looks pretty Japanese with its radial engine and sleek lines. When I recently came across a similar build at britmodelers.com, I thought that painting a Fw 190 green/grey and putting some Hinomarus on is logical and simple, but there's more in the subject than just cosmetics. I wanted a bit more... And while the concept remained simple, I had enough ideas and spare parts for a twin combo! In the end, the J10F was built as a pure interceptor and as a 'special purpose' night strike aircraft.
Basically, my limiting design idea for the J10F's design was the idea that Japan would not have received the Fw 190’s original BMW 801 radial engine, so that an alternative powerplant had to be fitted. I had hoped that this would have set the 'new' plane outwardly a bit apart from its German ancestor, and also make you look twice because the result would not be a 1:1 "Japanized" Fw 190 A/F. I tried, but I suppose that the effect is not as 'powerful' as intended – but judge for yourself?
The basic kits for both conversions come from Hobby Boss. It is a simple and clean kit, but with very good fit and engraved details. In an attempt to change the plane's look a little, I tried to transplant other engines - radials, too. Donation parts for both kits come from an Italeri Ju 188, which features two pairs of engines. The radials I used are actually BMW 801’s, too, but they lack the typical cooling fan and the cowlings are 3-4mm longer because they'd carry the engine mountings on the Ju 188's wings. Actually, the fuselage is minimal longer now, maybe 4-5mm, but the shape is still very close to the original Fw 190, so I think that this mod hardly is recognizable at all?
The change was a bit tricky, due to the massive fuselage of the Hobby Boss kit, but it worked. The new cowlings received new cooling louvres and exhaust pipes. New, four-bladed propellers were added, scratch-built from leftover Mosquito NF.30 propellers from the Airfix kit and drop tank front halves.
Otherwise, though, not much was changed, the two kits just differ in equipment details and received Matchbox pilot figures in order to cover up the bleak and very deep cockpit.
The interceptor:
As an interceptor I left the plane clean, without external ordnance. I wanted to emphasize its elegant look, which makes it look like a Ki-43 on casual glance, or even an A6M. The plane carries the normal gun armament (from a Fw 190 A-8), this is supposed to be the original/standard J10F mentioned above.
The night attacker:
The J10F1-G variant saw more modifications, including a new exhaust system with flame dampers built from scratch. Other special equipment comprises an IR sight in front of the canopy, flare protectors, the fuselage hardpoint and the scratch-built Ke-Go 110 bomb. In order to cover the deleted gun access panels under the wings, I added streamlined bomb shackles for two Japanese 60kg bombs each, donated from a Matchbox Ju 87 kit.
About the Ke-Go bomb
This bomb, which looks like a penguin, is a fantasy derivate of a real Japanese development series until summer 1945. In a nutshell, the Ke-Go bomb actually was one of the first “fire and forget” weapons I have heard of. With the guidance of a bolometer seeker and a self-correcting steering mechanism, the bomb would (only) be useable against strong and clear heat sources – a ship’s kettle at night, when surrounding heat level was low, would qualify, and the bomb would be guided by deviation and correction from that heat source - if it locked on correctly, though! My Ke-Go 110 is a smaller version of the original Ke-Go bombs, suitable for lighter planes.
Painting
Being an IJN plane, paint scheme choices for the J10F were rather limited - and since it is a whif plane I stuck to my policy that I rather use a simple/subtle paint scheme.
The interceptor:
For the clean and rather conservative interceptor I settled for a simple IJN Green/Gray livery (N. 2 ‘Aomidori-iro’, a bluish, very dark green and N.10 ‘Hairyokushoku’, respectively), with Testors 2116 and 2117 as basic tones. Yellow wing leading edges were added, cut from an aftermarket decal sheet. As a design twist I painted the engine cowling black, A6M-style. The propeller spinner was painted in red brown (typical Japanese WWII primer color), with an orange tip, matching the arrow symbol decal on the tail fin. The propeller blades were painted with Testor’s ‘Rubber’, #1183.
A slightly worn look was achieved through a light wash with black ink and some dry painting with paler shades of Green (Humbrol 91 and 185) and Aluminum, plus light exhaust marks and gun smoke residues with flat black. Some bare metal spots were added, which also highlight some details and add to the worn look.
All decals for the green fighter come from a Hobby Boss A6M, only the arrows come from the Hobby Boss He 162. Finally, everything was sealed under a semi-matte varnish, for a light shine to the surface – typical IJN machines appear to be rather shiny?
The night attacker:
This variant received a more fantastic and stealthy paint scheme - I wanted to set the plane apart from the clean and shiny interceptor: a grunty, desperate strike aircraft against overwhelming sea forces.
AFAIK, there had not been specific nocturnal cammo schemes at the IJNAS, except for all-green aircraft? A bit boring, I thought, esp. with a typical green/gray sister plane.
So I made up a personal variant: In a first step, upper surfaces were painted in a brownish-grey basic tone, AFAIK called ‘Ameiro’ – it is the color which was used on early Zeroes which were based on carriers, and the tone faded quickly to a light gray. This color is very similar to RAL 7014 ‘Fenstergrau’ and reminds of B.S. ‘Hemp’. I improvised it with a mix of Humbrol 141 (60%), 83 (35%) and a bit of 155 (5%). On top of that a dense array of dark green blotches (Humbrol 185, Chrome Green, at first, and later also with Humbrol 116 for more contrast) was applied, breaking up the plane’s lines and covering the light gray tone almost completely.
Undersides originally sported ‘Ameiro’, too, but they were painted as if they had been covered with a very dark gray tone in the field (Humbrol 67), even leaving out the hinomarus and flaking off everywhere. The black engine cowling was retained.
Hinomaru and squadron emblems come from the same Mitsubishi A6M from Hobby Boss as mentioned above, featuring even less markings. As a side note: I have never seen Hinomaru with a black(!) rim before? I am not certain if this is correct or an authentic modification - it matches the night fighter role perfectly, though. This time I chose a matte varnish, except for the cowling which received some streaks with more shiny semi-matte varnish.
In both cases, cockpit interior surfaces and landing gear wells were painted in ‘Aodake Iro’, simulated with a base of Aluminium (Humbrol 56) and a coat of translucent blue lacquer on top.
All in all, these pair of rather simple model kit was built in a couple of days, taking the pictures and waiting for good light took almost the same time! I am not 100% happy, because the engine mod is not as obvious as I expected, even though the four-bladed prop and the slightly elongated fuselage give the J10F a menacing and fast look, like a “Baby Tempest”.
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.

Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some Background:
The Ki-38 fighter was designed by the Tachikawa Aircraft Company Limited (立川飛行機株式会社, Tachikawa Hikōki Kabushiki Kaisha) near Tokyo, an aircraft manufacturer in the Empire of Japan, specializing primarily in aircraft for the Imperial Japanese Army Air Force. The Ki-38 prototype was produced in response to a December 1937 specification for a successor to the popular fixed-gear Nakajima Ki-27 Nate. The specification called for a top speed of 500 km/h (310 mph), a climb rate of 5,000 m (16,000 ft) in five minutes and a range of 800 km (500 mi). Maneuverability was to be at least as good as that of Ki-27.
When first flown in early January 1939, the Ki-38 prototype was a disappointment. Japanese test pilots complained that it was less maneuverable than the Ki-27 Nate and not much faster. Even though the competition was eventually won by the Ki-43, service trials determined the aircraft to hold sufficient promise to warrant further work, leading to the adoption of an expanded and strengthened wing and a more refined Mitsubishi Ha-102 (Army Type 100 1,050hp Air Cooled Radial) 14-cylinder air-cooled radial piston engine. During spring 1939, following the completion of further proving trials, an order for a pre-production batch of 25 aircraft was placed.
As a whole, the Ki-38 was an all-modern design consisting of all-metal skin and understructure construction with low-set monoplane wing appendages. The wings were straight in their general design with rounded tips and set well-forward of amidships. The engine was fitted to the extreme forward section of the fuselage in a traditional manner, powering a three-bladed propeller installation. Interestingly, the cockpit was also situated well-forward in the design, shortening the visual obstacle that was the engine compartment to some extent. However, views were still obstructed by the short engine housing to the front and the wings to the lower sides. The fuselage tapered at the rear to which a single vertical tail fin was affixed along with mid-mounted horizontal tailplanes. The undercarriage was retractable and of the "tail-dragger" arrangement consisting of two main single-wheeled landing gear legs and a fixed, diminutive tail wheel leg at the rear.
The series-production Ki-38-I was further modified to enhance its performance. These changes involved a major weight saving program, a slimmer and longer fuselage with bigger tail surfaces and a new, more streamlined bubble-style canopy that offered, even while bearing many struts, the pilot a very good all-round field of view.
In addition to good maneuverability, the Ki-38-I had a good top speed of more than 500 km/h (310 mph). The initial Ki-38 was armed with four 7.7 mm (0.303 in) Type 89 machine guns in the wings, but this soon turned out to be insufficient against armored Allied fighters and bombers. Quickly, the inner pair of weapons was, after just 50 aircraft, replaced with 12.7 mm (0.50 in) Ho-103 machine guns in the Ki-38-Ib (the initial version subsequently became the Ki-38-Ia), of which 75 were built. On board of the following Ki-38-Ic, the inner weapons were replaced with a pair of even heavier and more effective 20 mm (0.787 in) Ho-5 cannon, which required fairings for the ammunition under the wings and made this version easy to identify. The Ki-38-Ic became the most frequent variant, with 150 examples built.
All types also featured external hardpoints for a drop tank under the fuselage or a pair of bombs of up to 250 kg (550 lb) caliber under the wings. Late production aircraft were designated Ki-38-II. The pilot enjoyed a slightly taller canopy and a reflector gunsight in place of the earlier telescopic gunsight. The revised machines were also fitted with a 13 mm (0.51 in) armor plate for the pilot's head and back, and the aircraft's fuel tanks were coated in rubber to form a crude self-sealing tank. This was later replaced by a 3-layer rubber bladder, 8mm core construction, with 2mm oil-proof lamination. Some earlier aircraft were retrofitted with these elements, when available to the field workshops, and they dramatically improved the aircraft’s resilience to enemy fire. However, the bladder proved to be highly resistant only against light 7.7 mm (0.303 in) bullets but was not as effective against larger calibers. The Ki-38-II’s armament was the same as the Ki-38-Ic’s and 120 aircraft were built.
Ki-38 production started in November 1939 at the Tachikawa Hikoki KK and at the 1st Army Air Arsenal (Tachikawa Dai-Ichi Rikugun Kokusho) plants, also at Tachikawa. Although Tachikawa Hikoki successfully managed to enter into large-scale production of the Ki-38, the 1st Army Air Arsenal was less successful – hampered by a shortage of skilled workers, it was ordered to stop production after 49 Ki-38 were built, and Tachikawa ceased production of the Ki-38 altogether in favor of the Ki-43 in mid-1944.
Once it was identified and successfully distinguished from the IJA’s new Ki-43 “Oscar” and the IJN’s A6M “Zero” (Oscar), which both had very similar outlines, the Ki-38 received the Allied code name “Brad”. Even though it was not produced in the numbers of the Ki-43 or the A6M, the Ki-38 fought in China, Burma, the Malay Peninsula, New Guinea, the Philippines, South Pacific islands and the Japanese home islands. Like the Oscar and the Zero, the Ki-38 initially enjoyed air superiority in the skies of Malaya, Netherlands East Indies, Burma and New Guinea. This was partly due to the better performance of the Brad and partly due to the relatively small numbers of combat-ready Allied fighters, mostly the Curtiss P-36 Hawk, Curtiss P-40, Brewster Buffalo, Hawker Hurricane and Curtiss-Wright CW-21 in Asia and the Pacific during the first months of the war.
As the war progressed, however, the fighter suffered from the same weaknesses as its slower, fixed-gear Ki-27 "Nate" predecessor and the more advanced naval A6M Zero: light armor and less-than-effective self-sealing fuel tanks, which caused high casualties in combat. Its armament of four light machine guns also proved inadequate against the more heavily armored Allied aircraft. Both issues were more or less mended with improved versions, but the Ki-38 could never keep up with the enemy fighters’ development and potential. And as newer Allied aircraft were introduced, the Japanese were forced into a defensive war and most aircraft were flown by inexperienced pilots.

The kit and its assembly:
I always thought that the French Bloch MB 150 had some early WWII Japanese look to it, and with this idea I recently procured a relatively cheap Heller kit for this conversion project that would yield the purely fictional Tachikawa Ki-38 for the IJA – even though the Ki-38 existed as a Kawasaki project and eventually became the Ki-45, so that the 38 as kitai number was never actively used.
The Heller MB 150 is a vintage kit, and it is not a good one. You get raised panel lines, poor details (the engine is a joke) and mediocre fit. If you want a good MB 150 in 1:72, look IMHO elsewhere.
For the Ki-38 I wanted to retain most of the hull, the first basic change was the integration of a cowling from a Japanese Mitsubishi Ha-102 two-row radial (left over from an Airfix Ki-46 “Dinah”), which also received a new three-blade propeller with a different spinner on a metal axis inside. The engine also received some more interior details, even though the spinner blocks most sight.
The next, more radical move was to replace the MB 150’s spinal cockpit fairing with a bubble canopy and a lowered back – I found a very old and glue-tinted canopy from a Matchbox A6M in the spares box, and it turned out to be very suitable for the Ki-38. However, cleaning the clear piece was quite challenging, because all raised struts had to be sanded away to get rid of the old glue and paint residues, and re-polishing it back to a more or less translucent state took several turns with ever finer sandpaper, polishing paste and soft polishing mops on a mini drill. The spine was re-created with 2C-putty and the canopy was blended into it and into the fuselage with several PSR turns.
Inside, I used a different pilot figure (which would later be hard to see, though), added a fuel tank behind the seat with some supporting struts and inserted a piece of styrene sheet to separate the landing gear well from the cockpit – OOB it’s simply open.
The landing gear was basically taken OOB, I just replaced the original tail skid with a wheel and modified the wheels with hub covers, because the old kit wants you to push them onto long axis’ with knobs at their tips so that they remain turnable. Meh!
The fairings under the guns in the wings (barrels scratched from the MB 150’s OOB parts) are conformal underwing fuel tanks from a late Seafire (Special Hobby kit).
Painting and markings:
The initial plan was a simple green/grey IJA livery, but the model looked SO much like an A6M that I rather decided to give it a more elaborate paint scheme. I eventually found an interesting camouflage on a Mitsubishi Ki-51 “Sonia” attack plane, even though without indications concerning its unit, time frame or theater of operations (even though I assume that it was used in the China-Burma-India theater): an overall light grey base, onto which opaque green contrast fields/stripes had been added, and the remaining light grey upper areas were overpainted with thin sinuous lines of the same green. This was adapted onto the Ki-38 with a basis in Humbrol 167 (RAF Barley Grey) and FS 34102 (Humbrol 117) for the green cammo. I also wanted to weather the model considerably, as a measure to hide some hardware flaws, so that a partial “primer coat” with Aluminum (Revell 99) was added to several areas, to shine through later. The yellow ID markings on the wings’ leading edges were painted with Humbrol 69. The propeller blades were painted with Humbrol 180, the spinner in a slightly lighter mix of 180 and 160.
Interior surfaces were painted with a dull yellowish green, a mix of Revell 16 and 42, just the inside of the landing gear covers became grey as the outside, in a fashion very similar to early Ki-43s.
The decals came form various sources, including a Hasegawa Ki-61 sheet for the unit markings and some stencils and hinomaru in suitable sizes from a generic roundel sheet.
Some dry-brushing with light grey was done to emphasize edges and details, and some soot stains were added with graphite to the exhausts and the guns. Finally, the kit was sealed with matt acrylic varnish, some more dry-brushing with aluminum was done, esp. around the cockpit, and position lights were added with translucent paint.
An unexpected result – I was not prepared that the modified MB 150 looks THAT much like a Mitsubishi A6M or the Ki-43! There’s even an Fw 190-ish feel to it, from certain angles. O.K., the canopy actually comes from a Zero and the cowling looks very similar, too. But the overall similarity is baffling, just the tail is the most distinguishing feature! However, due to the poor basis and the almost blind canopy donor, the model is far from stellar or presentable – but some in-flight shots look pretty convincing, and even the camouflage appears to be quite effective over wooded terrain.
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture

Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.

The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

Some background:
The Messerschmitt Me 262 Schwalbe or Sturmvogel (English: "Swallow"/ "Storm Bird") was the world's second operational jet-powered fighter aircraft. Design work started before World War II began, but engine problems and top-level interference kept the aircraft from operational status with the Luftwaffe until mid-1944.
The Me 262 was faster, and more heavily-armed than any Allied fighter, including the British jet-powered Gloster Meteor which entered service in the UK a month earlier than the Me 262. One of the most advanced aviation designs in operational use during World War II, the Me 262 was used in a variety of roles, including light bomber, reconnaissance, and even experimental night fighter versions.
The latter was a variant that was direly needed, and the development of a fast night fighter led to several prototypes and an operational interim version. Several two-seat trainer variants of the Me 262, the Me 262 B-1a, had been adapted through the Umrüst-Bausatz 1 factory refit package as night fighters, complete with on-board FuG 218 Neptun high-VHF band radar, using Hirschgeweih ("stag's antlers") antennae with a set of shorter dipole elements than the Lichtenstein SN-2 had used, as the B-1a/U1 version. Serving with 10 Staffel, Nachtjagdgeschwader 11, near Berlin, these few aircraft (alongside several single-seat examples) accounted for most of the 13 Mosquitoes lost over Berlin in the first three months of 1945.
Anyway, the Me 262 B-1a's deficiencies were clear from the start and in parallel Messerschmitt already worked on a dedicated night fighter variant that would offer a better performance (primarily concerning range and speed) than the converted trainer, which was, nevertheless, rushed into service and gathered valuable information.
Initially, the idea of a night-fighter 262 was developed independently by Messerschmitt as the Me 262B-2. It was to have a longer fuselage accommodating the two crew, internal fuel tanks with the capacity comparable to that of a single-seat variant, and a Berlin radar antenna hidden inside the modified nose cone. However, by the end of 1944 the war situation deteriorated so rapidly that it was realized that an interim solution must be found before the B-2 could reach production status.
Instead of the complex B-2 Messerschmitt also proposed a less ambitious approach which would use as many Me 262 fighter components as possible, primarily the aerodynamic surfaces, the engines and the landing gear. This proposal was accepted by the RLM in September 1944 and became the Me 262 G.
This variant received a completely re-designed and aerodynamically refined fuselage. It was, from the start, tailored to carry the heavy radar equipment, a second crew member as radar operator and navigator and a bigger fuselage tank (the trainers that were converted into night fighters had part of their fuel capacity reduced to make place for the 2nd seat). The result was a slender, streamlined aircraft with a considerably smaller cross section than the Me 262 day fighter/bomber.
The crew was separated into two cabins in front and behind the fuselage main tank. This arrangement also offered enough space for a "Schräge Musik" installation (a pair of guns firing upwards, either two 20mm MG 151/20 or two 30mm MK 108), to allow the night fighter to attack RAF bombers from their belly blind spot.
The main armament was a pair of MK 103 30mm cannons - while this was a reduction of firepower compared to the Me 262 B-1a, the MK 103 was much more accurate, had a longer range and a much higher muzzle velocity (860 m/s (2,822 ft/s) versus 540 m/s (1,800 ft/s) with HE/M), so that targets could be engaged at longer distance with less expenditure of ammunition and further outside of the bombers' defensive fire.
The first operational version, the G-1, was ready for service in December 1944 and exclusively delivered to the NJG 6, based in southern Germany after withdrawal from Romania and regrouping.The G-1 still carried the FuG 218 Neptun radar, still coupled with a high drag Hirschgeweih antenna and with a FuG 350 Zc Naxos radar warning receiver/detector, but the G-1 was still faster than the B-1a and had a longer range on internal fuel than the B-1a with two external 300l drop tanks, which further reduced top speed. Later versions (G-2) were supposed to carry the more modern FuG 240 with a parabolic dish antenna under a more treamlined thimble nose radome, and a single seat long range reconnaissance version (G-3) was also planned, which would carry no guns but an camera array in the radar operators's place.
Anyway, only about 20 Me 262 G-1 were delivered to NJG 6 at all, and probably less than a dozen were operational when Germany surrendered. The G-3 recce variant remained on the drawing board, while two prototypes with radomes for the FuG 240 were under construction and underwent wind tunnel tests.

The kit and its assembly:
Connoisseurs will immediately recognize this kitbash - and the Me 262 G was spawned from the thought that the Japanese Ki-46 was such an elegant aircraft - wouldn't a jet version somehow make sense? So, initially this was supposed to become a Hikoki '46 model, but when I held some Me 262 parts next to the Ki-46's fuselage the idea of a Luftwaffe night fighter was born.
And this actually worked better than expected. This whif is a kitbash of an Airfix Ki-46 fuselage with wings, tail, engines, landing gear and Hirschgeweih from a Revell Me 262 B-1a.
Mating the parts went pretty straightforward, even though I made a mistake when I measured the position of the wing under the fuselage. Somehow it ended up 4-5mm too close to the nose - while the flaw was acceptable I decided to add a 5mm plug behind the pilot cockpit to compensate... And the added length just underlines the elegant Ki-46 lines.
In order to keep the model on its three feet lots of lead beads were hidden in the fuselage, the nose tip and even the front ends of the engine nacelles. Since the Ki-46 fuselage is considerably smaller than the Me 262's I had to fill the wing roots with putty, but that was a rather easy task.
Painting and markings:
I wanted something different from other German night fighters/bombers I had already built, yet a simple livery. Since many German night fighters left the factories in an overall RLM 76 finish I used this as a basis and just added mottles in RLM 75 on the upper surfaces - inspired by a Ta 154 Moskito night fighter prototype.
The cockpits were painted in very dark grey (RLM 66) while the landing gear and the respective wells were painted with RLM 02. Everything very conventional.
The markings were puzzled together - the national markings and stencils come from the Revell Me 262 B-1a sheet while the registration was created from single aftermarket letters, matching a hypothetical aircraft from 4. Staffel, II./NJG 6 in code and colors.
The kit received a light black in wash and some dry-brushing to emphasize panel lines. On the fuselage, however, I painted some panel lines with a pencil, since the Airfix Ki-46 is completely bare of details. Some soot stains around the guns were added with graphite and finally everything sealed under matt acrylic varnish.
A simple kitbashing project, and I am amazed how plausible the Ki-46/Me 262 mix looks, despite the mistake I made with the wing position. I wonder how a Ki-46 III with its streamlined cockpit would look in this case?
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947.

Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings (lacking the slight sweepback of the Me 262) and tail surfaces. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kg) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most of them were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose, but a few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank, what markedly limited the aircraft’s range but was accepted for a trainer.
Some operational Kitsukas also had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A small number, both single- and two-seaters, were also equipped with an experimental centimeter waveband FD-2 radar in the nose with an “antler” antenna array, similar to German radar sets of the time. In order to fit the electronics, the machines typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style) behind the cockpit. These machine received the suffix “-S” and flew a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system.
Proposed follow-on versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study, two damaged day fighters were handed over to the RAF and transferred to RAF Seletar, where the airframes were, together with spares, combined into a single flyworthy J9N1 designated “FE (Foreign Equipment) 269” and tested by the Allied Technical Air Intelligence Unit. These tests did not last long, though, because the engines were in poor condition and only lasted for four test flights until one failed fatally and caused a fire: at least one compressor blade had separated and ruptured fuel and oil lines. The pilot was able to leave the burning and disintegrating aircraft but was hit by the tail and was badly injured. However, he survived, but FE 269 crashed into the Street of Sohor.
Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD.
The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The kit and its assembly:
This is submission #4 for the “Captured!” group build at whatifmodellers.com in late 2020. Loot from WWII certainly makes a good theme, and I remembered a real world J2M3 that I had built some time ago – in RAF markings and tested by the ATAIU-SEA in Singapore in late the 1945. For a more whiffy touch I delved through The Stash™ for options and found an AZ Models Nakajima “Kikka” single seater – as Japan’s first jet fighter, a suitable contender, even more so because no aircraft of this type made it in time to frontline units.
The AZ Models kit is a simple affair, but that's also its problem. In the box things looked quite good, detail level is on par with a classic Matchbox kit. But unlike a Matchbox kit, the AZ Models offering does not go together... I had to fight everywhere with poor fit, lack of locator pins, ejection marks - anything a short run model kit can throw at you! Things turned out really bad: One upper wing half was bent so much that I tried to counter the flaw with force - and the part broke! Furthermore, PSR was necessary almost everywhere – but especially around the wing/engine pod intersection and the area where the wings are inserted into the fuselage. Huh! What worked surprisingly well is the IP canopy, though.
Personal additions are lowered flaps (easy to realize) and some additional struts for the landing gear.
Painting and markings:
The captured aircraft theme was settled from the start, but I wanted to offer more than just a “rebadging” with RAF roundels on an IJN green/grey airframe. In order to add some visual spice, my idea became to present an irregular "one-aircraft-made-from-two-wrecks" finish, with parts in differing tones and even some primed or bare metal areas.
I gave the model an overall coat of aluminum (with Red Stars added, this would have made another interesting whif!) and started adding cloudy shades of IJN Green (ModelMaster and Tamiya) and sections with RAF Dark Green to the upper surfaces, and light grey underneath, with the aluminum underneath shining through here and there. One engine was furthermore painted in a shaggy Japanese primer red brown. I furthermore added overpainted IJN markings with U.S. olive drab for some more contrast, even though would later be at least partly hidden under decals.
The cockpit was painted in a greenish yellow primer (trying to simulate a typical “bamboo” shade that was used in some late-war IJN cockpits), while the landing gear and the flaps’ interior was painted in dull aluminum (Humbrol 56).
A black ink washing was applied for more weathering and contrast. the yellow leading edge markings were created with decal material. RAF roundels came from the scrap box, the “FE 269” code was created with single white 3mm letters. The “ATAIU-SEA” titles were painted with a thin brush and white acrylic paint, and sanded down a bit once dry, for a weathered look.
Finally, the kit received a mixed coat of semi-gloss and matt acrylic varnish.
I had the Kikka earmarked for a different build, but I think this ATAIU livery adds an interesting twist to the model, it looks pretty plausible. Besides, the Kitsuka is a pretty, elegant aircraft, and it's relatively small (even petit) when compared with a contemporary Me 262 or a Meteor!

Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings (lacking the slight sweepback of the Me 262) and tail surfaces. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kg) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most of them were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose, but a few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank, what markedly limited the aircraft’s range but was accepted for a trainer.
Some operational Kitsukas also had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A small number, both single- and two-seaters, were also equipped with an experimental centimeter waveband FD-2 radar in the nose with an “antler” antenna array, similar to German radar sets of the time. In order to fit the electronics, the machines typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style) behind the cockpit. These machine received the suffix “-S” and flew a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system.
Proposed follow-on versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study, two damaged day fighters were handed over to the RAF and transferred to RAF Seletar, where the airframes were, together with spares, combined into a single flyworthy J9N1 designated “FE (Foreign Equipment) 269” and tested by the Allied Technical Air Intelligence Unit. These tests did not last long, though, because the engines were in poor condition and only lasted for four test flights until one failed fatally and caused a fire: at least one compressor blade had separated and ruptured fuel and oil lines. The pilot was able to leave the burning and disintegrating aircraft but was hit by the tail and was badly injured. However, he survived, but FE 269 crashed into the Street of Sohor.
Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD.
The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.
For example, the low-price Champion had arrived in spring 1939 with a lightweight L-head six of 164.3 cubic inches. This went to 169.6 cubic inches and 80 horsepower for 1941-49, then added five horsepower. The costlier Commanders used a larger six dating from Studebaker's 1932 Rockne. By 1949, this engine was up to 245.6 cubic inches and 100 horsepower.
The 1947-1949 models were a great sales success, lifting Studebaker to eighth in the U.S. industry with a market share of 4.12 percent. Production was at record levels. So were corporate profits -- $27.56 million in calendar 1949 alone. Things looked great, and were about to get even better.
The bullet-nose idea had been on Bourke's drawing board since 1940-1941, when he first sketched several elements of the eventual 1950 Studebaker. Chief among them was a protruding nose with flanking pontoon fenders suggesting the front of an airplane.
Public reaction is what matters in the auto industry, and "The Next Look" 1950 Studebaker, featuring the company's signature "bullet-nose" look for the first time, was a winner -- more popular than even the 1947. Sales began in August 1949, nearly a month ahead of other 1950 cars.
For all this hoopla, the 1950s were identical to the 1947-49 models except for the bullet nose, minor trim, and vertical instead of horizontal taillights. However, the new front end added an inch to wheelbases, taking Champions to 113, Commanders to 120. Both lines again offered two- and four-door sedans, a convertible, and a five-passenger Starlight coupe with its distinctive panoramic rear window.
Demand for the bullet-nose '50s proved so strong that Studebaker added a third shift at its large South Bend factory and ran its Southern California and Hamilton, Ontario, assembly plants at or near capacity. A 14-month model "year" (July 15, 1949, to September 27, 1950) produced 343,164 cars -- the most for any vehicle in Studebaker's long history. By the end of 1950, company employment was up to 25,000, a peacetime record.

Some background:
In the summer of 1941, Kogiken (a contraction of Kokugijutsu Kenkyujo) formed a design group under the leadership of Ando Sheigo. The task was to study Japanese aviation technology in terms of what was possible at present and in the near future. Additionally, some effort was to be spent on reviewing the aircraft technology of other countries. From the results the group was to assemble and draft proposals for aircraft to fill various pre-determined roles: heavy fighter, light bomber, heavy bomber and reconnaissance. For a bigger idea pool, IJA's main aircraft providers, Kawasaki and Tachikawa, were invited to join the group, too.
One central design demand was to incorporate a select group of engines, primarily radials but also the Ha-40 inline engine, a licence-built DB 601A of German origin. In September 1941 the design inspection ended completion, and among one of the five fighter designs (all from Kogiken), the so-called 'Plan I Type C' interceptor offered an exotic layout which was to maximize the potential of the Ha-40 engine, which had been successfully used in the IJA’s Ki-61 ‘Hien’ fighter.
This compact single-seater featured a conventional layout, but the engine had been placed behind the cockpit, similar to the P-39. But in order to keep the nose free for a heavy cannon armament, which would in turn keep the wings free from heavy gun and ammunition loads, the Ha-40 drove a three-bladed pusher propeller in the tail through an extension shaft. The propeller was protected from ground contact through an additional fin under the fuselage. As another novel feature and consequence, the aircraft had a tricycle undercarriage, the nose wheel retracted backwards, the main landing gear inwards. The Ha-40’s radiator bath was split and situated on the aircraft's flanks, similar to the arrangement of the Ki-78 experimental high speed aircraft.
The concept’s idea was to concentrate all heavy elements in the smallest possible airframe, close to its CG and longitudinal axis, so that agility and overall performance could be improved without need for new/more powerful engine developments.
The pilot enjoyed very good forward view, even though no solution for a safe exit in case of emergency was provided at first. The powerful armament consisted of a single 37mm Ho-204 cannon in the nose, flanked by a pair of 20mm Ho-5 cannons in the lower fuselage. As an alternative, a single 57mm Ho-401 cannon was even considered, as well as a set of four Ho-5 or three 30mm Ho-15 cannons - the spacious nose compartment allowed many options.
The design was so convincing that a go-ahead was quickly given for three prototypes, the first of which flew in August 1943. While the tricycle undercarriage and the rather small angle of attack for starting and landing called for special flying techniques, the aircraft behaved well and kept its promise of high agility, esp. at medium heights.
The prototypes were soon troubled with ever serious problems caused by vibrations from the extension shaft. This could finally be mended through new bearings and the introduction of a reduction gear, which would now drive a five-bladed pusher propeller on serial aircraft – it might be that Japan received technical support from Germany, e .g. in the form of blueprints and test reports from the Göppingen Gö 9 research aircraft or its successor, the formidable Dornier Do 335 “Pfeil”.
Anyway, the revised power shaft arrangement needed more internal space. As a consequence, the radiator installation was modified for the serial aircraft: It was re-located into a single bath under the fuselage, at the wing's trailing edge. While this was not aerodynamically as clean as the original flank solution, maintenance was much easier and furthermore this simpler installation saved enough weight to compensate for the reduction gear. Additionally, a primitive ejection seat (powered by pressurized air) was introduced and an emergency mechanism which would allow to blow away the upper or lower fin, or both.
After flight test had been completed in April 1944, Rikugun immediately started serial production at Dai-Ichi Rikugun Kokusho, located in Tachikawa. The modified serial aircraft was given the official designation 'Ki-124-I' and was christened ‘shoufuu’ (しょうふう, ’Maple’). Production started slowly, at first due to the lack of Ha-40 engines. Initial production aircraft met front line service in September 1944, and these initially suffered heavy losses because of the type’s unfamiliar handling - not through enemy confrontation, though. Many landing accidents occurred, esp. in the hands of inexperienced pilots.
On the other side, the Ki-124 offered considerable handling advantages in comparison with the Ki-61 Hien, and it was faster in level flight. As a side effect, the unique engine and propeller arrangement made the aircraft very silent - it was very popular for reconnaissance missions at low level, as well as for night missions. On the downside, the slender aircraft was only designed as a cannon-armed fighter – external loads like bombs or air-to-ground missiles, even drop tanks, were not part of the interceptor design.
Army units to be equipped with this model included the following Sentai: 5th, 17th, 18th, 20th, 59th, 111th, 112th, 200th and 244th and the 81st Independent Fighter Company. Along with the previously named Army air units, pilots were trained through the Akeno and Hitachi (Mito) Army Flying Schools. Many of the Akeno and Hitachi instructors, who were often seconded from operational units, flew combat missions, too. Tthis deployment was a notable spreading out of the very few fighters that were operational, but many of these wings were only partially re-equipped, anyway.
The Ki-124 made its combat debut on the night of 12th October 1944 and scored its first victory on 7th April 1945, when a Ki-124 flown by Master Sergeant Yasuo Hiema of the 18th Sentai claimed a B-29 after "attacking the formation again and again".
After the bombing of the Dai-Ichi Rikugun Kokusho plant and the slow deliveries of components by the satellite plants, production rates of the Ki-124 began to dwindle more and more, and in the course of the following months, less and less units were delivered. Finally, production ended due to the bombing in mid- 1945, with only 118 units of the Ki-124-I delivered.
An overall assessment of the effectiveness of the Ki-124 rated it highly in agility, and a well-handled Ki-124 was able to outmanoeuvre any American fighter, including the formidable P-51D Mustangs and the P-47N Thunderbolts which were escorting the B-29 raids over Japan by that time. Furthermore, the Ki-124, which received the code name ‘Ike’ from the USAF, was comparable in speed, especially at medium altitudes. In the hands of an experienced pilot, the Ki-124 was a deadly opponent and, together with the Army's Ki-84, Ki-100 and the Navy's Kawanishi N1K-J, the only other Japanese fighters being able to defeat the latest Allied types.

The kit and its assembly
This fantasy aircraft is the outcome when you look at a crappy kit and ask, "What CAN you actually make from it...?". The kit in question is Amodel's Soviet Ticheranovov Ti-302 rocket interceptor in 1:72 - a “short run” (= appalling) quality kit. Nothing fits together, the material is questionable, best thing is that the injected canopy actually is actually clear and that the inside of the main landing gear covers HAVE a structure. But the rest...(*shudder*)?
Anyway, I got that kit for cheap some years ago and never had an idea what to do with it, until... I wondered if I could not turn the tail-sitter TI-302 into ‘something’ with a tricycle undercarriage? The lines are almost there, but propulsion was the next issue. A jet, maybe? And who would have made/used it?
Inspiration struck when I read about the innovative Kogiken planning group under Ando Sheigo, and with its compact size I was certain that it would become something Japanese. Since the jet age was during WWII not as far progressed as in Europe, I decided to make a propeller aircraft from it, keeping the jet-like cockpit, though. But instead of a pull arrangement (P-39 style) I wanted to try an exotic pusher layout.
The TI-302 airframe was basically kept, but had to be modified accordingly for the totally new propulsion concept. Biggest issue was the much longer tricycle landing gear - while the nose wheel and its well found a neat place under the cockpit, the main landing gear had to be moved back.
I found a simple solution: I just reversed the lower part of the wing, so that the original TI-302 landing gear well ended up at the wings’ trailing egde. The track had to be widened in order to accept the longer struts, though, but that was a simple task. The new front wheel was puzzled together from spare parts, the main landing gear struts come from a P-51.
Fitting the propeller was not much of an issue - it took the place of the original TI-302 rocket engine, in a slightly shortened fuselage. The new propeller was built from scratch, it is a massive 1:100 750lb bomb, cut to size and with single propeller blades glued to it in 72° angles, and is mounted with a metal axis, so that it can turn freely. In order to protect the propeller from ground contact I also added a fin under the lower rear fuselage, which comes from a Matchbox Supermarine Spitfire.
The original cockpit is non-existent, so I added a pilot figure in order to conceal the bleak interior and the tons of lead in the nose. The cockpit is rather tiny, anyway, so that it was - together with the added floor for the front gear well - pretty difficult to get the pilot into it!
The radiator comes IIRC from a Hawker Hurricane, and some added parts on the flanks like exhaust stubs, carburetor intake or simple covers enhance the otherwise bleak surface of the kit.
All in all, nothing fancy and no structural modifications - just external cosmetics. But the result is convincing!
Painting
While the tones are authentic, the paint scheme is fantasy, and I wanted to keep things rather simple and subtle.
In an initial step, the whole model was painted in Aluminum with Revell Aqua Color, as a kind of primer. On top of that, a thin and uneven coat of enamels were applied with a brush: IJA Green on the top sides, and IJN Grey on the lower sides (Testors 2114 and 2115, respectively). In order to add some unusual style, the waterline was raised and received a very wavy shape.
After anything had dried thoroughly, I wet-sanded the upper coat, so that more of the Aluminum could shimmer through, for a worn/flaky look. The result is surprisingly good.
All interior surfaces were painted with Testors 2119, "Aodake Iro", the distinctive translucent corrosion protection varnish you find on/in many Japanese WWII aircraft.
Markings were puzzled together. Most of them come from a very old MicroScale sheet for various IJA types. The yellow ID bands on the wings' leading edges were cut from decal sheet - a convenient alternative to masking and painting by hand.
Finally, the kit received some painted panel lines, done with RLM 70 and FS 34096 (both Testors, too) on the upper sides and Sky "S" on the grey areas. Some soot stains were added to the exhausts and the guns, too, as well as some silver on the leading edges.
A simple conversion, quick but effective, done in a couple of days as a ‘side dish’. Reminds a bit of the German He 162 jet fighter, but it breathes a whiffy, Japanese aura. And while the finish is not perfect and some details like the pretty cramped cockpit don’t look THAT good (after all, the original TI-302 does NOT have anything under the pilot's seat...), overall look and impression are better than expected.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Yokosuka J1Y was a land-based interceptor for the Imperial Japanese Navy Air Service (IJN/大日本帝國海軍航空隊, Dai-Nippon Teikoku Kaigun Kōkū-tai) that was based upon a research aircraft and introduced into service during the final months of WWII. Work on the J1Y commenced at the Yokosuka Naval Air Technical Arsenal (海軍航空技術廠, Kaigun Kōkū Gijutsu-shō) during 1942 and 1943, in the midst of the Second World War. The J1Y was initially intended to test the benefits of different aircraft layouts in order to exploit the available engines’ potential further, albeit the aircraft had been designed from the start in a fashion that was suitable for combat and easily adaptable into a light fighter aircraft. It would eventually be developed into Yokusuka’s only fighter project.
The J1Y was an unorthodox twin-boom pusher configuration fighter aircraft. It featured a mid-mounted wing, a tricycle landing gear arrangement, and was furnished with heavy forward-firing armament. The fuselage was primarily composed of plywood for the forward section and aluminum throughout the aft section, in order to save critical war material. The advantages of the pusher design were of an unobstructed forward view for the pilot, while the armament could also be concentrated in the nose, so that most of the aircraft’s heavy elements were concentrated around the mutual center of gravity. However, a major drawback was difficulty in escaping from the aircraft in an emergency, as the pilot could get drawn into the propeller blades, and the tail surfaces posed an imminent danger, too.
The J1Y1 test aircraft was powered by a 700 kW (940 hp) Nakajima Sakae 12 engine. A pair of intakes in the wings’ roots ducted cooling air to the engine, which was mounted at the egg-shaped fuselage’s tail, as well as to a pair of oil coolers that were buried in the thickened wing roots. Despite the aircraft’s tubby shape, it was a very clean design with an excellent weight distribution.
During the ensuing tests and flight trials in late 1943, the J1Y1 proved to be superior to the comparable Mitsubishi A6M2 “Zero” in many respects, so that the Imperial Japanese Navy Aviation Bureau (海軍航空本部, Kaigun Kōkū Hombu) became interested enough to eventually order a fully capable combat aircraft variant in early 1944: the J1Y2.
Development of the J1Y2 lasted until mid-1944. Outwardly, the aircraft differed only slightly from the J1Y1 test aircraft, of which four had been built. The internal structure was strengthened, esp. around the engine mount, because the fighter version was to be powered by the Mitsubishi Kinsei Model 48 radial engine which delivered 1,080 hp (810 kW). Since this engine had a slightly bigger diameter, the tight cowling had to be modified and now featured small bulges for its fourteen-cylinder heads, creating a characteristic ring of small bumps around the rear fuselage. The dorsal carburetor air scoop had to be enlarged, too.
The J1Y1’s four-blade propeller was replaced by a six-blade propeller – a measure that was necessary to convert the engine’s raised power output into sufficient propulsion, while exploiting the limited possible propeller disc diameter between the tail booms and keeping sufficient ground clearance.
Armor plates were added to the nose section and behind the pilot’s seat, but protection remained relatively light. In order to extend the J1Y1’s limited range of only 750 km (470 mi, 400 nmi), two additional 150l fuel tanks were added to the inner wings behind the landing gear wells, partly extending into the tail booms, even though they were not self-sealing like the main fuel tank behind the cockpit. Tilting air brakes were installed on the wings, enabling the J1Y1 to manoeuvre into a stable firing position behind slower aircraft. Armament consisted of a pair of 20 mm Type 99-2 cannon, flanking the front wheel well, supplemented by a pair of 7.7 mm (.303 in) Type 97 machine guns, which were rather intended as spotting rifles: they fired tracer rounds with the same trajectory as the 20 mm rounds, and gave off a flash and puff of white smoke on impact, so that 20 mm ammunition could be saved. Upon IJN introduction in August 1944, the J1Y was christened “Akaei” (アカエイ, “Stingray”). The Allied reporting name was "Ron"
However, teething development problems stemming from the Kasei engine cooling system and the main undercarriage members led to a slowdown in production. And when the Boeing B-29 Superfortress appeared, the J1Y2’s performance, esp. at height, was not sufficient anymore. Being not suited for high-altitude operations, and lacking internal space to accommodate a turbocharger, the IJN’s interest in the aircraft waned and resources were rather allocated to more promising types like the Mitsubishi J2M, despite its development problems, too. However, the J1Y2’s heavy gun armament supplied effective firepower and the use of dive and zoom tactics allowed it to score occasionally. It was also a very agile aircraft, esp. at medium altitude, so that production switched in January 1945, after 75 J1Y2s had been built, to the J1Y3.
The ultimate variant of the “Akaei” featured a new, even more powerful Mitsubishi Kinsei 62 engine with 1,163 kW (1,560 hp). Outwardly, this variant differed from its predecessor by a different exhaust arrangement: instead of the J1Y2’s two exhaust pipes, the J1Y3 featured individual exhaust, hidden under seven aerodynamic fairings, in order to exploit residual thrust and therefore further improve performance – resulting in even more bumps and fairing around the engine cowling. For the more powerful engine, and also because of cooling problems, the carburetor scoop was enlarged even more, so that an auxiliary cooling intake could be integrated.
Even though the armament nominally remained unchanged, supply shortages and field modifications in order to lighten the aircraft saw many J1Y3s with only two Type 99 cannons installed and the empty machine gun ports faired over. Some J1Y3s also carried gun 13.2 mm (.51 in) Type 3 heavy machine guns instead of the cannons, becoming designated J1Y3a. Due to ammunition shortages, some machines were converted in field workshops to this standard, too.
The J1Y3 arrived at IJN units in March 1945, but only a few were operational until the end of hostilities in the PTO, probably only around 40 aircraft were eventually delivered.

The kit and its assembly:
This build followed a spontaneous inspiration, and it became another contribution to the “in the navy” group build at whatifmodlers.com in early 2020. I actually had the Vampire kit already stashed away for a while, and the plan to convert it into a propeller-driven aircraft with a radial engine and a pusher configuration à la Saab 21 had been there – but I lacked an idea for an operator, so that I could build the background story around it. With the “in the navy” theme, it suddenly clicked – why not the IJN? The Vampire is a rather compact and slender aircraft, so there’s IMHO some Japanese “style” in the design, and after the torturous build of HMS Cerberus I wanted some kind of relief.
The Vampire kit is the vintage Heller mold from 1979, but actually in a mid-Nineties Revell re-boxing. Like many other Heller kits, it comes with raised panels, but detail is sufficient (nice dashboard, landing gear is O.K., and the kit comes with separate air brakes) – the molds seem to be a bit worn, though, I guess a “true” old Heller kit is more crisp and would be the better choice.
At the core of the conversion plan was the implantation of a radial engine in place of the jet exhaust. I found a donor part from a Hobby Boss MC.200 Saetta – a bit vintage, but it had the right diameter and I actually liked the ring of bulges on the cowling. Internally, a styrene tube adapter was added for a freely spinning propeller.
While adding a prop to a jet seems to be an easy task, the real challenge behind such a conversion are the many other changes that have to be made to the airframe. This includes a (considerably) longer landing gear and the respective wells, but also the tail surfaces. There’s also the question how the new radial engine actually breathes, where exhausts can be located, and a cooling system is necessary, too.
Work started with the search for new landing gear struts, and I also used different wheels – for instance, the main wheels come from a Hasegawa F9F Panther, while the front wheel comes from a Frog He 162 and is probably 35 years old(!). In order to make the longer struts fit into the airframe, I elongated the wells in the wings towards the fuselage, so that the track width was reduced – but with the Vampire’s small airframe and original wide stance, this was no serious problem. From the inside, they were faired with styrene profile material, and the extended covers were scratched – esp. the parts for the wings, with their bulges for the tail boom tips, were fiddly.
In order to move the overall look a bit further away from the Vampire, I completely changed the fin arrangement. The original, rounded and rather small fins and the bullet-shaped fairings that hold the stabilizer outside of the original exhaust blast were deleted. Once the wings and the tail booms were added to the fuselage, the stabilizer was mounted between the booms, in a slightly lower position. For the new fins I wanted a layout that would, beyond a more squarish shape that would better match the wings, protect the propeller. Therefore, I used stabilizers from a KP Yak-23; each was cut into two pieces, tailored further to match the rest of the aircraft, and glued in positions above and underneath the booms. Looks quite weird, as if the aircraft had been designed upside down, but it’s a rather pragmatic solution that has already been used on some pusher designs in the past.
The six-blade propeller was scratched from a spinner, carved from a thick piece of sprue, plus a metal axis and six single blades that were taken from the rather wacky one-piece propellers of Airfix’s Ki-46 kit.
Hollow steel needles were used as barrels for the Type 99 cannons in the lower fuselage.
Painting and markings:
Once more, a rather conservative approach – and the IJN was not creative when it came to liveries. Almost every aircraft carried a typical dark green over light grey scheme, with minimal individual markings or tactical codes. I wanted to stay true to this concept but decided to simplify the scheme even more since this would be a late-war aircraft, pressed into service under rather dire supply circumstances. This resulted in a NMF livery (basis is Tamiya XF-60, which turned out soemwaht grainy, plus some Polished Aluminum Metallizer from Humbrol on top), with only the upper surfaces camouflaged with IJN Green (ModelMaster) without primer underneath, resulting in a somewhat flaky and worn look. Since they are rather slender, the tail booms were completely painted in IJN green, too.
The yellow ID markings on the wings’ leading edges were created with decal material (TL Modellbau), the cockpit interior as well as the landing gear wells were painted with a mix of silver and blue, mimicking the typical “aodake iro” protective clear lacquer of Japanese IJN aircraft. The struts were painted black, according to A6M museum exhibits. The propeller blades ware painted in a red-brown primer, a mix of Humbrol 160 and 180.
Markings were taken from a PrintScale Yokosuka N1K2 decal sheet and mixed from two aircraft. Placing the fuselage hinomaru was tricky – the natural choice would have been the tail booms, but they’d be very small, so I rather put them on the fuselage under the cockpit. With the individual aircraft number added to the meatball, it looks now like a racing aircraft, though...
Finally, the kit received some soot stains and dry-brushing with aluminum, and everything was sealed with semi-gloss acrylic varnish from Italeri - even though the result is a little too glossy for my taste, but I left it that way.
A rather quick build, but structurally not much from the Vampire was changed. The new engine was relatievly easy to integrate - the other small bits like the fins, the propeller and esp. the landing gear took more time. The result looks quite odd - the whole thing has also a certain German touch? Could have worked well with a BMW 801 engine, too!

Some background
The history of Focke Wulf's Fw 190 in Japan started with a rejection: in 1943 a single FW 190 A-5 had been supplied to Japan for evaluation, but at first, the type was not put into production by the Japanese. Anyway, the results of the study by Japanese engineers were incorporated in the design of the Ki-61 fighter. This evaluation did not go unnoticed, since the type received the Allied code-name 'Fred'.
By that time, the teething development problems of Mitubishi's J2M ‘Raiden’ (Thunderbolt) 'Jack' led to a slowdown in production. Biggest issues were the Kasei engine, an unreliable propeller pitch change mechanism and the main undercarriage members. Another drawback of the type was that its design put emphasis on performance and pilot protection rather than maneuverability. By the time the Fw 190 was tested, only fourteen J2M had been completed.
To make matters even worse, the Mitsubishi A7M 'Reppu' fighter was also behind schedule, so that replacements for the A6M 'Zero', backbone of the IJN’s air force, were overdue.
This situation left the Imperial Japanese Navy without a land-based interceptor. The first few produced J2M2 were delivered to the development units in December 1942 but further trials and improvements took almost a year, and it took until June 1944 that the ‘Raiden’ could make its combat debut, during the Battle of the Philippine Sea.
While the Raiden was to be developed further for the high-altitude interceptor role, the IJN decided in January 1944 to adopt the highly effective Fw 190 as a supplementary interceptor for medium heights - only as a stop-gap at first, but the type quickly evolved into various sub-variants, much like in Germany.
License production of the adopted Fw 190 started at Hitachi in May 1944. The original airframe was modified to cater to Japanese needs and customs, and the most obvious difference of the J10F1, how the plane was officially called, was the use of the Mitsubishi MK4R Kasei 23c radial engine instead of the original BMW 801. It was a modified version of the engine in the J2M, but simplified and made more reliable. The engine produced 1.820hp and drove a four-bladed propeller. Another distinctive feature was a small fin fillet, which compensated directional instability due to the longer forward fuselage.
By its pilots, the J10F quickly became called “hueruge” (フエルゲル), a transcription of the Fw 190's German nickname "Würger" (=Shrike).
Variants:
J10F1
The original main variant with the MK4R Kasei 23e and armed with 2× 13.2 mm Type 3 machine guns and 4× 20 mm two Type 99 Model 2 cannons, 354 aircraft produced.
While no official sub-variant was developed or designated, single machines differed considerably in equipment. This included field-modifications like reduced armament for better performance or ground-attack equipment, e .g. racks for a total of four unguided 60kg air-to-air missiles under the outer wings.
J10F1-G
In late 1945 a few J10F1 were modified for the anti-ship role and night attacks, and they received the "-G" suffix for their new land-based bomber role. These planes had a reduced gun armament, flame dampers and an IR sight, similar to the German “Spanner” device.
Most of these planes were to carry special weapons, like a single indigenous Ke-Go 110 heat-seeking guided bomb under the belly, or, alternatively, a copy of the German Bv 246 "Hagelkorn" gliding bomb, which had been delivered to Japan in 1944 for tests and adopted for production. To allow more space under the fuselage while carrying these bombs on the ground, some of these aircraft had a longer tail wheel strut fitted. Additionally, tests were made with a torpedo on the centerline hardpoint. It is uncertain if these weapons were actually used in combat, though.
J10F2
The only variant that was developed so far that it entered service, incorporating many detail modifications and improvements. These included thicker armored glass in the cabin's windshield (from 5.5 cm/2.2” to 7.6cm/3”) and extra armor plating behind the pilot's seat. The wing skinning was thickened in localized areas to allow for a further increase in dive speed. A water-methanol engine boost was added, which allowed an engine output of 2.050 hp for short periods, which boosted the top speed to 695 km/h. 52 were produced.
J10F3
High altitude project with a pressurized cabin, a larger wing span of 11.96 m (39 ft 2 in) and a turbo-supercharged MK4R-C Kasei 23c engine, with the turbo-supercharger mounted behind the cockpit (itself made wider). This doubled the altitude at which the engine could produce its rated power, from 15,750ft up to 30,185ft. The J10F3 only carried two 20mm cannons in the wing roots, but had two extra oblique-firing 20mm cannon installed aft of the cockpit for use against high flying American B-29 bombers (much like the German "Schräge Musik" installments). Two prototypes were completed in June 1945, but the turbo-supercharger proved troublesome, and no further aircraft of this type were produced.
From late 1944 on, the J10F1 was quickly thrown into service and became a nasty surprise for Allied aircraft. The modified Focke Wulf design proved to be agile, fast and much tougher than earlier Japanese fighters, coupled with a relatively heavy armament. Beyond interception duties, the J10F1 was frequently employed in close support and anti-shipping tasks, since its low level handling and ordnance load was excellent.
Its only drawback was - as with the original Fw 190 - that performance dropped at heights above 6.000m. This should not have posed a problem with the J2M, but that type's delay left the Allied high-altitude bomber attacks relatively unharmed, so that the J10F3 version was hastily developed, but failed to realize. In Germany, the similar situation resulted in the Fw 190 D-9 variant and finally in the superb Ta-152.

The kit and its assembly
The 'Japanese Fw 190' is a popular what-if topic, so I wanted to add my interpretation to the plethora of whifs and replicas of the real test machine. Actually, a clean Fw 190 looks pretty Japanese with its radial engine and sleek lines. When I recently came across a similar build at britmodelers.com, I thought that painting a Fw 190 green/grey and putting some Hinomarus on is logical and simple, but there's more in the subject than just cosmetics. I wanted a bit more... And while the concept remained simple, I had enough ideas and spare parts for a twin combo! In the end, the J10F was built as a pure interceptor and as a 'special purpose' night strike aircraft.
Basically, my limiting design idea for the J10F's design was the idea that Japan would not have received the Fw 190’s original BMW 801 radial engine, so that an alternative powerplant had to be fitted. I had hoped that this would have set the 'new' plane outwardly a bit apart from its German ancestor, and also make you look twice because the result would not be a 1:1 "Japanized" Fw 190 A/F. I tried, but I suppose that the effect is not as 'powerful' as intended – but judge for yourself?
The basic kits for both conversions come from Hobby Boss. It is a simple and clean kit, but with very good fit and engraved details. In an attempt to change the plane's look a little, I tried to transplant other engines - radials, too. Donation parts for both kits come from an Italeri Ju 188, which features two pairs of engines. The radials I used are actually BMW 801’s, too, but they lack the typical cooling fan and the cowlings are 3-4mm longer because they'd carry the engine mountings on the Ju 188's wings. Actually, the fuselage is minimal longer now, maybe 4-5mm, but the shape is still very close to the original Fw 190, so I think that this mod hardly is recognizable at all?
The change was a bit tricky, due to the massive fuselage of the Hobby Boss kit, but it worked. The new cowlings received new cooling louvres and exhaust pipes. New, four-bladed propellers were added, scratch-built from leftover Mosquito NF.30 propellers from the Airfix kit and drop tank front halves.
Otherwise, though, not much was changed, the two kits just differ in equipment details and received Matchbox pilot figures in order to cover up the bleak and very deep cockpit.
The interceptor:
As an interceptor I left the plane clean, without external ordnance. I wanted to emphasize its elegant look, which makes it look like a Ki-43 on casual glance, or even an A6M. The plane carries the normal gun armament (from a Fw 190 A-8), this is supposed to be the original/standard J10F mentioned above.
The night attacker:
The J10F1-G variant saw more modifications, including a new exhaust system with flame dampers built from scratch. Other special equipment comprises an IR sight in front of the canopy, flare protectors, the fuselage hardpoint and the scratch-built Ke-Go 110 bomb. In order to cover the deleted gun access panels under the wings, I added streamlined bomb shackles for two Japanese 60kg bombs each, donated from a Matchbox Ju 87 kit.
About the Ke-Go bomb
This bomb, which looks like a penguin, is a fantasy derivate of a real Japanese development series until summer 1945. In a nutshell, the Ke-Go bomb actually was one of the first “fire and forget” weapons I have heard of. With the guidance of a bolometer seeker and a self-correcting steering mechanism, the bomb would (only) be useable against strong and clear heat sources – a ship’s kettle at night, when surrounding heat level was low, would qualify, and the bomb would be guided by deviation and correction from that heat source - if it locked on correctly, though! My Ke-Go 110 is a smaller version of the original Ke-Go bombs, suitable for lighter planes.
Painting
Being an IJN plane, paint scheme choices for the J10F were rather limited - and since it is a whif plane I stuck to my policy that I rather use a simple/subtle paint scheme.
The interceptor:
For the clean and rather conservative interceptor I settled for a simple IJN Green/Gray livery (N. 2 ‘Aomidori-iro’, a bluish, very dark green and N.10 ‘Hairyokushoku’, respectively), with Testors 2116 and 2117 as basic tones. Yellow wing leading edges were added, cut from an aftermarket decal sheet. As a design twist I painted the engine cowling black, A6M-style. The propeller spinner was painted in red brown (typical Japanese WWII primer color), with an orange tip, matching the arrow symbol decal on the tail fin. The propeller blades were painted with Testor’s ‘Rubber’, #1183.
A slightly worn look was achieved through a light wash with black ink and some dry painting with paler shades of Green (Humbrol 91 and 185) and Aluminum, plus light exhaust marks and gun smoke residues with flat black. Some bare metal spots were added, which also highlight some details and add to the worn look.
All decals for the green fighter come from a Hobby Boss A6M, only the arrows come from the Hobby Boss He 162. Finally, everything was sealed under a semi-matte varnish, for a light shine to the surface – typical IJN machines appear to be rather shiny?
The night attacker:
This variant received a more fantastic and stealthy paint scheme - I wanted to set the plane apart from the clean and shiny interceptor: a grunty, desperate strike aircraft against overwhelming sea forces.
AFAIK, there had not been specific nocturnal cammo schemes at the IJNAS, except for all-green aircraft? A bit boring, I thought, esp. with a typical green/gray sister plane.
So I made up a personal variant: In a first step, upper surfaces were painted in a brownish-grey basic tone, AFAIK called ‘Ameiro’ – it is the color which was used on early Zeroes which were based on carriers, and the tone faded quickly to a light gray. This color is very similar to RAL 7014 ‘Fenstergrau’ and reminds of B.S. ‘Hemp’. I improvised it with a mix of Humbrol 141 (60%), 83 (35%) and a bit of 155 (5%). On top of that a dense array of dark green blotches (Humbrol 185, Chrome Green, at first, and later also with Humbrol 116 for more contrast) was applied, breaking up the plane’s lines and covering the light gray tone almost completely.
Undersides originally sported ‘Ameiro’, too, but they were painted as if they had been covered with a very dark gray tone in the field (Humbrol 67), even leaving out the hinomarus and flaking off everywhere. The black engine cowling was retained.
Hinomaru and squadron emblems come from the same Mitsubishi A6M from Hobby Boss as mentioned above, featuring even less markings. As a side note: I have never seen Hinomaru with a black(!) rim before? I am not certain if this is correct or an authentic modification - it matches the night fighter role perfectly, though. This time I chose a matte varnish, except for the cowling which received some streaks with more shiny semi-matte varnish.
In both cases, cockpit interior surfaces and landing gear wells were painted in ‘Aodake Iro’, simulated with a base of Aluminium (Humbrol 56) and a coat of translucent blue lacquer on top.
All in all, these pair of rather simple model kit was built in a couple of days, taking the pictures and waiting for good light took almost the same time! I am not 100% happy, because the engine mod is not as obvious as I expected, even though the four-bladed prop and the slightly elongated fuselage give the J10F a menacing and fast look, like a “Baby Tempest”.
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.
For example, the low-price Champion had arrived in spring 1939 with a lightweight L-head six of 164.3 cubic inches. This went to 169.6 cubic inches and 80 horsepower for 1941-49, then added five horsepower. The costlier Commanders used a larger six dating from Studebaker's 1932 Rockne. By 1949, this engine was up to 245.6 cubic inches and 100 horsepower.
The 1947-1949 models were a great sales success, lifting Studebaker to eighth in the U.S. industry with a market share of 4.12 percent. Production was at record levels. So were corporate profits -- $27.56 million in calendar 1949 alone. Things looked great, and were about to get even better.
The bullet-nose idea had been on Bourke's drawing board since 1940-1941, when he first sketched several elements of the eventual 1950 Studebaker. Chief among them was a protruding nose with flanking pontoon fenders suggesting the front of an airplane.
Public reaction is what matters in the auto industry, and "The Next Look" 1950 Studebaker, featuring the company's signature "bullet-nose" look for the first time, was a winner -- more popular than even the 1947. Sales began in August 1949, nearly a month ahead of other 1950 cars.
For all this hoopla, the 1950s were identical to the 1947-49 models except for the bullet nose, minor trim, and vertical instead of horizontal taillights. However, the new front end added an inch to wheelbases, taking Champions to 113, Commanders to 120. Both lines again offered two- and four-door sedans, a convertible, and a five-passenger Starlight coupe with its distinctive panoramic rear window.
Demand for the bullet-nose '50s proved so strong that Studebaker added a third shift at its large South Bend factory and ran its Southern California and Hamilton, Ontario, assembly plants at or near capacity. A 14-month model "year" (July 15, 1949, to September 27, 1950) produced 343,164 cars -- the most for any vehicle in Studebaker's long history. By the end of 1950, company employment was up to 25,000, a peacetime record.

It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.

Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Cadillac 1948 Series 62 Fastback.
Cadillac had been one of the leading builders of luxury cars in the US between the wars. As part of the greater General Motors Corporation, Cadillac was well placed to resume car production after the end of WW II. Not only to resume production, but to fund the development of all new models, incorporating an all-new engine (for 1949), and advanced styling influenced by developments in aviation during the war.
This new styling and bodies were first seen in 1948.
For 1948, the Series 62 was moved to the same 126 in (3,200 mm) chassis as the Series 61, making the vehicles virtually identical. The main difference, apart from extra chrome, was the availability of a convertible model. Distinguishing features included grooved bright metal front fender gravel guards, rocker panel brightwork, chevron style chrome slashes below taillights and slightly richer interior trim. Also in 1948 the first tail fins were added. Sales fell to 34,213, nevertheless accounting for a record 68% of all Cadillacs sold.
A combination of factors allowed Cadillac to firmly place itself at the forefront of the luxury market, and stay there for the next 40 years.
This Lockheed P-38 Lightning from 1941, and 1948 Cadillac Series 62 Fastback Coupe has been created in Lego miniland-scale for Flickr LUGNuts 79th Build Challenge, - "LUGNuts goes Wingnuts", - featuring automotive vehicles named after, inspired by, or related to aircraft.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Nakajima Ki-104 was a further development of the Ki-87; the latter was a Japanese high-altitude fighter-interceptor of World War II, a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.
The Ki-87 was one of several designs of various manufacturers developed in response to American B-29 Superfortress raids on the Home Islands. The Ki-87 followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began.
The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the high-performance, tandem-engine Tachikawa Ki-94-I, while the Ki-87 under the lead of Kunihiro Aoki was developed as a fall-back project, using less stringent requirements.
Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945.
The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and from the sixth prototype the Nakajima fighter was to have that arrangement. Construction was further delayed due to problems with the electrical undercarriage and the turbo-supercharger itself. As a consequence, the first Ki-87 prototype was not completed until February 1945; it first flew in April, but only five test flights were completed.
A further variant, the Ki-87-II, powered by a 3,000 hp Nakajima Ha217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt. Due to the long development period of the Ki-87, several major structural changes were made, too, that eventually changed the aircraft so much that it received a new, separate kitai number and became the Ki-104.
Kunihiro Aoki's new design was approved by the Koku Hombu, and an order was placed for one static test airframe, three prototypes, and eighteen pre-production aircraft. Only 2 prototypes were built in the event; the first was equipped with a single 1,895 kW (2,541 hp) Nakajima Ha219 [Ha-44] engine, driving a 4-blade, but the second one received the stronger Nakajima Ha217 (Ha-46) and a 6-blade propeller.
The pre-production machines (Ki-104-I or -Tei) were all produced with Ha217 engines, but featured various four-bladed propeller (-a, -b) designs as well as the new 6-blade propeller (-c). Compared to the prototypes, armament was beefed up from a pair of 20mm Ho-5 and a pair of 30mm Ho-155-I cannons in the wings to four of the new, more compact Ho-155-II cannons (originally designed for the unsuccessful Ki-102 assault aircraft and optimized for wing installation).
All pre-production Ki-104-Is were allocated to an independent IJA Headquarter Flight where they were tested alongside established fighters in the defence of the Tokyo region. Based on this 3rd Independent Flight's unit marking, a completely black tail with the unit's emblem, the Ki-104s were inofficially called Ic '黒の尾'/'Kurono-'o, which literally means "Black Tail".
The first operational Ki-104s reached this unit in spring 1945 and saw limited use against the incoming streams of B-29 bombers (2 unconfirmed downings in the Tokyo region). After these initial contacts that left a serious impression the new type received the USAF code name "Cooper", but the hostilities' soon end however stopped any further work and serial production. No Ki-104 survived the war.

The kit and its assembly:
This whif is the result of many ideas and occasions. First of all, I had a leftover six-blade propeller from a Hasegawa J7W Shinden in stock. Then I recently had an eye on kits of late Japanese high altitude fighters with turbosuperchargers, like the Ki-91-II or the Ki-106. These are available from RS Models, but rare and rather costly. And I wondered how a P-47 might look like without its deep belly? All this was finally thrown into a big idea stew, and the Ki-104 is the home-made hardware result!
As a side note: the Ki-104 was a real IJA project, AFAIK based/related to the Tachikawa Ki-94-I twin-boom/push-pull high altitude fighter, a re-worked, more conventional design. Information is sparese and it never reached any hardware stage and remained a paper project as the Rikugun Kogiken Ki-104; I just "revived" the number for my whif, but maybe the real Ki-104 could have looked like it... ;-)
The kit is a bashing of various parts and pieces:
- Fuselage and wing roots from an Academy P-47-25
- Wings from an Ark Model Supermarine Attacker (ex Novo)
- Tail fin is a modified part of a Matchbox Ju 188 stabilizer
- The stabilizers are outer sections from a Matchbox Douglas F3D Skyknight
- Cowling comes from an ART Model Grumman F8F Bearcat, the engine was scratched
- Propeller from a Hasegawa J7W Shinden
- Main wheels from a Matchbox F6F Hellcat
My choice fell onto the Academy Thunderbolt because it has engraved panel lines, offers the bubble canopy as well as good fit and detail. The belly duct had simply been sliced off, and the opening later faired over with styrene sheet and putty.
The Bearcat cowling was chosen because it had very good fitting width in order to match with the P-47 fuselage, and it turned out to be a very good choice - even though I had to add a dorsal connection, a simple styrene wedge, to create a good profile.
Inside, the engine consists of a reversed Hobby Boss F6F engine, with a fan dummy that covers any view on non-existent interior details... A styrene tube was added, into which a metal axis can be inserted. The latter holds the propeller, so that it can spin with little hindrance.
The Attacker wings were chosen because of their "modern" laminar profile - the Novo kit is horrible, but acceptable for donations. And the risen panel lines and rivets should later do great work during the weathering process... OOB, the Attacker wings had too little span for the big P-47, so I decided to mount the Thunderbolt's OOB wings and cut them at a suitable point: maybe 0.5", just where the large wheel fairings for the main landing gear ends.
The intersection with the Attacker wings is almost perfect in depth and width, relatively little putty work was necessary. I just had to cut out new landing gear well parts.
With the new wing shape, the tail surfaces had to be changed accordingly, with parts from a Matchbox Skyknight and a highly modified piece from a Matchbox Ju 188 stabilizer.
The OOB cockpit and landing gear was retained, I just replaced the main wheels with slightly more delicate alternatives from a Matchbox F6F Hellcat.
Once the basic bodywork was done I added the exhaust arrangement under the fuselage; the outlets are oil cooler parts from a Fw 190A, the air scoop once belonged to a Martin Marauder and the long ducts are actually HO scale roof rails. The oil cooler under the engine comes from a Hobby Boss La-7.
Pretty wild mix, but it works surprisingly well!
Painting and markings:
Even though this was supposed to become a late WWII IJA fighter, I did neither want the stereotype NMF look nor the classic green/grey livery or a respective mottled scheme. What I finally settled upon, though, took a long while to manifest, and it looks ...odd.
I wanted a camouflage scheme, but none of the more exotic real world options was fine for me; there had been fighters with black upper surfaces, bright blue ones, or blue mottle on top of NMF. But all this did not convince me, and I eventually created an experimental scheme. And the paint was supposed to look heavily worn, as if the paint had been applied directly onto the bare metal, without primer, so that it chips and flakes off easily.
The tones were supposed to be suitable for high altitudes, but not the classic IJA colors - nothing even close. eventuelly I came up with an all-around turquoise green (ModelMaster Fulcrum Grey Green) plus a pale grey-green (ModelMaster RAF Dark Slate Grey) as contrast for the upper sides. Sick combination, yes, esp. with the Aluminum shining through, which was applied first as a kind of acrylic primer. The camouflage paint was carefully brushed on top of that, with panel-wise strokes from back to front. Tedious, but effective.
The black tail was applied similarly, it is a free interpretation of real IJA markings; for instance, the 244th Sentai arcraft bore all-red tail sections. Black is an uncommon color, but since I wanted to create fictional squadron markings, too, this was a suitable concept. And it looks cool and mysterious...
The cockpit interior was painted with Aodake Iro (Modelmaster), the section behind the pilot's seat and where the sliding canopy moves on the outside, were painted with IJA Dark Green - just an odd idea. In front of the cockpit a black anti glare panel was added. The landing gear and the respective wells were painted with Steel Metallizer (just to set them apart from the lighter Aluminum all around). The propeller was painted in reddish brown tones, the spinner in Humbrol 160 and the blades in 173.
After this basic painting the kit received a black ink wash, and decals were applied. These were taken from various aftermarket sheets, including generic, white and yellow sheet for the Home Defence markings on wings and fuselage, the white fuselage trim or the yellow ID markings on the wings' leading edges.
As next step the complete kit was carefully wet-sanded, primarily from front to back, so that more of the aluminum primer showed through, the decals (esp. the Hinomaru) were worn out and the camouflage paint on top lost some of its hard edges.
The sanding residues had to be cleaned away thoroughly (with a soft toothbrush and lots of water), and then, repairs, e .g. where the bare plastic came through, as well as extra effects with dry-painted, lighter camouflage tones were done. Final cosmetics also include oil and dirt stains with Tamiya"Smoke", also applied by brush.
Once everything was dry and clean (despite the kit's look), everything was sealed under a coat of varnish - a 3:1 mix of matt and gloss Revell Acrylics.
A complex and lengthy painting process, but I think the effort paid out because the procedure mimicks the structure and look of a worn paint job instead of trying to look like it when you paint a cammo scheme and add metal effects "on top". This works for small chips, but not for the flaked look I had been looking for.
The Ki-104 turned out to be a very conclusive kitbashing - I think that the P-47-with-Attacker-wings-and-new-cowling bears more potential, and I might try it again, e. g. for a naval Thunderbolt development?
New pics of an old kit, but one I hold pretty dear: because it was an accidental find (and never expected that such official merchandise existed at all!) and because I like (if not love) the manga where it comes from and in which the J7W has a brief appearance in one of the series' early stories.
I found this Hasegawa kit in a model kit shop for Japanese animation in Berlin, in a dark shop corner.
The kit itself is the standard 1:72 Hasegawa scale model of the WWII Shinden prototype. New water sliding decals and painting instructions were included, and the kit has been mostly built "out of the box".
The "paradigm" for this machine, which is supposed to be the (fictional) second Shinden prototyp which had been buried before the American invasion and lost, stems from a special edition of the "Oh, my goddess" manga, a one-shot story during the first or second series of books called "On a Wing and a Prayer", around 1997.
Actually, I was a bit suprised by the kit's colors, since the manga mentions a "green fuselage" - but this could also have been a translation error. Bit it is not: later I found out that "green" and "blue" use the same word in Japanese, so the confusion comes from the outsiders' point fo view. ;)
Hasegawa recommends white and a dark petrol blue, which is a non-standard color and has to be mixed manually. Other weird color details include the brown propeller (O.K., it's IJN primer, but looks pretty weird in the overall combo!) and the bright red landing gear insides... but since there are no other color references available (the manga is B/W), I stuck with Hasegawa's official instructions.
The kit itself is of high quality (typical Hasegawa standard) and the parts fit well.
The tricky job is the painting, though, with lots of white and the very complicated blue contrast areas with hard and straight demarcation lines, which are especially hard to paint on the fuselage, because of the air intake bulgings. I did not get it as good as I wanted to...
Another tricky part are the decals for some of the blue areas. While the idea of having some of the delicate shapes as a water decal at hand, matching the color of the printed decals and the rest of the paint is another task - you will recognize some areas with color differences ;)
Besides these troubles, some details in the cockpit and at the landing gear were added - overall a very good kit, but due to the delicate color scheme nothing for beginners or those faint at heart!
As a side note: In the meantime (well, many years have passed since I built this one), there's an 1:32 OOB offering of this specific bird from literature available, from Zoukei Moura. Funny to see that the company chose a much brighter blue, and it differs in some other details (e .g. having a white canopy framing), too.
The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.
For example, the low-price Champion had arrived in spring 1939 with a lightweight L-head six of 164.3 cubic inches. This went to 169.6 cubic inches and 80 horsepower for 1941-49, then added five horsepower. The costlier Commanders used a larger six dating from Studebaker's 1932 Rockne. By 1949, this engine was up to 245.6 cubic inches and 100 horsepower.
The 1947-1949 models were a great sales success, lifting Studebaker to eighth in the U.S. industry with a market share of 4.12 percent. Production was at record levels. So were corporate profits -- $27.56 million in calendar 1949 alone. Things looked great, and were about to get even better.
The bullet-nose idea had been on Bourke's drawing board since 1940-1941, when he first sketched several elements of the eventual 1950 Studebaker. Chief among them was a protruding nose with flanking pontoon fenders suggesting the front of an airplane.
Public reaction is what matters in the auto industry, and "The Next Look" 1950 Studebaker, featuring the company's signature "bullet-nose" look for the first time, was a winner -- more popular than even the 1947. Sales began in August 1949, nearly a month ahead of other 1950 cars.
For all this hoopla, the 1950s were identical to the 1947-49 models except for the bullet nose, minor trim, and vertical instead of horizontal taillights. However, the new front end added an inch to wheelbases, taking Champions to 113, Commanders to 120. Both lines again offered two- and four-door sedans, a convertible, and a five-passenger Starlight coupe with its distinctive panoramic rear window.
Demand for the bullet-nose '50s proved so strong that Studebaker added a third shift at its large South Bend factory and ran its Southern California and Hamilton, Ontario, assembly plants at or near capacity. A 14-month model "year" (July 15, 1949, to September 27, 1950) produced 343,164 cars -- the most for any vehicle in Studebaker's long history. By the end of 1950, company employment was up to 25,000, a peacetime record.

The Lockheed P-38 Lightning was a World War II American fighter aircraft built by Lockheed. Developed to a United States Army Air Corps requirement, the P-38 had distinctive twin booms and a single, central nacelle containing the cockpit and armament. Named "fork-tailed devil" (der Gabelschwanz-Teufel) by the Luftwaffe and "two planes, one pilot" (2飛行機、1パイロット Ni hikōki, ippairotto?) by the Japanese, the P-38 was used in a number of roles, including dive bombing, level bombing, ground-attack, night fighting, photoreconnaissance missions, and extensively as a long-range escort fighter when equipped with drop tanks under its wings.
The P-38 was used most successfully in the Pacific Theater of Operations and the China-Burma-India Theater of Operations as the mount of America's top aces, Richard Bong (40 victories) and Thomas McGuire (38 victories). In the South West Pacific theater, the P-38 was the primary long-range fighter of United States Army Air Forces until the appearance of large numbers of P-51D Mustangs toward the end of the war.
The P-38 was unusually quiet for a fighter, the exhaust muffled by the turbo-superchargers. It was extremely forgiving, and could be mishandled in many ways, but the rate of roll in the early versions was too slow for it to excel as a dogfighter. The P-38 was the only American fighter aircraft in production throughout American involvement in the war, from Pearl Harbor to Victory over Japan Day.
Design and development[edit]
Lockheed designed the P-38 in response to a February 1937 specification from the United States Army Air Corps. Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenant Benjamin S. Kelsey (later Brigadier General) and First Lieutenant Gordon P. Saville (later General) for a twin-engine, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at high altitude." Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat. Specifications called for a maximum airspeed of at least 360 mph (580 km/h) at altitude, and a climb to 20,000 ft (6,100 m) within six minutes, the toughest set of specifications USAAC had ever presented. The unbuilt Vultee XP1015 was designed to the same requirement, but was not advanced enough to merit further investigation. A similar single-engine proposal was issued at the same time, Circular Proposal X-609, in response to which the Bell P-39 Airacobra was designed. Both proposals required liquid-cooled Allison V-1710 engines with turbo-superchargers and gave extra points for tricycle landing gear.
The Lockheed design team, under the direction of Hall Hibbard and Clarence "Kelly" Johnson, considered a range of twin-engine configurations, including both engines in a central fuselage with push-pull propellers.
The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform. The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns, with 200 rpg, two .30-caliber (7.62 mm) Brownings, with 500 rpg, and a T1 Army Ordnance 23-mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25-mm Hotchkiss aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a larger John Browning-designed, Colt-made M9 37-mm (1.46 in) autocannon with 15 rounds replaced the T1. The 15 rounds were in three 5-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano 20-mm (.79 in) autocannon with 150 rounds.
P-38 armament, concentrated in the nose of the aircraft
Clustering all the armament in the nose was unlike most other U.S. aircraft, which used wing-mounted guns with trajectories set up to crisscross at one or more points in a convergence zone. Nose-mounted guns did not suffer from having their useful ranges limited by pattern convergence, meaning that good pilots could shoot much farther. A Lightning could reliably hit targets at any range up to 1,000 yd (910 m), whereas other fighters had to pick a single convergence range between 100 and 250 yd (230 m). The clustered weapons had a "buzz saw" effect on any target at the receiving end, making the aircraft effective for strafing as well. The rate of fire was about 650 rounds per minute for the 20×110-mm cannon round (130-gram shell) at a muzzle velocity of about 2,887 ft/s (880 m/s), and for the .50-caliber machine guns (43–48-gram rounds), about 850 rpm at 2,756 ft/s (840 m/s) velocity. Combined rate of fire was over 4,000 rpm with roughly every sixth projectile a 20-mm shell. The duration of sustained firing for the 20-mm cannon and .50-caliber machine guns was approximately 14 seconds and 35 seconds, respectively.
The Lockheed design incorporated tricycle undercarriage and a bubble canopy, and featured two 1,000-hp (746 kW) turbo-supercharged 12-cylinder Allison V-1710 engines fitted with counter-rotating propellers to eliminate the effect of engine torque, with the superchargers positioned behind the engines, with the exhaust side of the units exposed along the dorsal surfaces of the booms. Counter-rotation was achieved by the use of "handed" engines, which meant that the crankshaft of each engine turned in the opposite direction of its counterpart. The V-12 engines required changing only the spark plug firing order in order for the direction of the crankshaft to be reversed, according to the General Motors Allison V-1710 Service School Handbook.
It was the first American fighter to make extensive use of stainless steel and smooth, flush-riveted butt-jointed aluminum skin panels. It was also the first fighter to fly faster than 400 mph (640 km/h).
Pacific theater
Wartime poster encouraging greater production of P-38s
The P-38 was used most extensively and successfully in the Pacific theater, where it proved ideally suited, combining excellent performance with very long range, and had the added reliability of two engines for long missions over water. The P-38 was used in a variety of roles, especially escorting bombers at altitudes between 18–25,000 ft (5,500-7,600 m). The P-38 was credited with destroying more Japanese aircraft than any other USAAF fighter. Freezing cockpits were not a problem at low altitude in the tropics. In fact, since there was no way to open a window while in flight as it caused buffeting by setting up turbulence through the tailplane, it was often too hot; pilots taking low altitude assignments would often fly stripped down to shorts, tennis shoes, and parachute. While the P-38 could not out-turn the A6M Zero and most other Japanese fighters when flying below 200 mph (320 km/h), its superior speed coupled with a good rate of climb meant that it could utilize energy tactics, making multiple high-speed passes at its target. Also, its focused firepower was even more deadly to lightly armored Japanese warplanes than to the Germans'. The concentrated, parallel stream of bullets allowed aerial victory at much longer distances than fighters carrying wing guns. It is therefore ironic that Dick Bong, the United States' highest-scoring World War II air ace (40 victories solely in P-38s), would fly directly at his targets to make sure he hit them (as he himself acknowledged his poor shooting ability), in some cases flying through the debris of his target (and on one occasion colliding with an enemy aircraft which was claimed as a "probable" victory). The twin Allison engines performed admirably in the Pacific.
Postwar operations[edit]
The end of the war left the USAAF with thousands of P-38s rendered obsolete by the jet age. The last P-38s in service with the United States Air Force were retired in 1949.[82] A total of 100 late-model P-38L and F-5 Lightnings were acquired by Italy through an agreement dated April 1946. Delivered, after refurbishing, at the rate of one per month, they finally were all sent to the AMI by 1952. The Lightnings served in 4 Stormo and other units including 3 Stormo, flying reconnaissance over the Balkans, ground attack, naval cooperation and air superiority missions. Due to unfamiliarity in operating heavy fighters, old engines, and pilot errors, a large number of P-38s were lost in at least 30 accidents, many of them fatal. Despite this, many Italian pilots liked the P-38 because of its excellent visibility on the ground and stability on takeoff. The Italian P-38s were phased out in 1956; none survived the inevitable scrapyard.
Surplus P-38s were also used by other foreign air forces with 12 sold to Honduras and 15 retained by China. Six F-5s and two unarmed black two-seater P-38s were operated by the Dominican Air Force based in San Isidro Airbase, Dominican Republic in 1947. The majority of wartime Lightnings present in the continental U.S. at the end of the war were put up for sale for US$1,200 apiece; the rest were scrapped. P-38s in distant theaters of war were bulldozed into piles and abandoned or scrapped; very few avoided that fate.
Variants:
Over 10,000 Lightnings were manufactured in all, becoming the only U.S. combat aircraft that remained in continuous production throughout the duration of American participation in World War II. The Lightning had a major effect on other aircraft; its wing, in a scaled-up form, was used on the L-049 Constellation.
Popular culture
1950 Studebaker Champion
Harley Earl arranged for several of his designers to view a YP-38 prototype shortly before World War II, and its design directly inspired the tail fins of the 1948–1949 Cadillac
The P-38 was also the inspiration for Raymond Loewy and his design team at Studebaker for the 1950 and 1951 model-year Studebakers.
The whine of the speeder bike engines in Return of the Jedi was partly achieved by recording the engine noise of a P-38, combined with that of a North American P-51 Mustang.
Studebaker Champion Convertible (1950)
Studebaker was proud to be "First by Far With a Postwar Car," but after three years on the market, its vehicles very much needed a distinctive new look for their carried-over bodies. In fact, the 1950-1951 Studebaker origins were as a counterpoint to the post-war car, when celebrated styling consultant Raymond Loewy decided his staff should look to the heavens for inspiration.
Perhaps no automaker is more identified with a single design than Studebaker with its 1950-1951 "bullet-nose" cars. The feisty South Bend independent didn't invent the "spinner" front end -- the 1948 Tucker and 1949-1950 Ford used similar themes, as have several European models. Studebaker's styling differed mainly in degree.
Ads called it "The Next Look," implying it would start a trend. It didn't, but that mattered little to company executives, who were content to chalk up sales unmatched in Studebaker's previous 48 years of auto production and in any of the next 16.
When Studebaker contracted Loewy Associates to design all-new 1947 models, Exner and Cole worked up their own proposal in secret -- with the advantage of engineering parameters not made available to the "official" Loewy team. It was this design that management ultimately chose and introduced in mid 1946. Studebaker was two years ahead of the competition -- "First by Far With a Postwar Car," as ads blared. To Exner's chagrin, advertising credited Loewy with the new styling.
Loewy promptly fired Exner for his treachery and replaced him with Bob Bourke, Exner's subordinate and friend. Bourke, who made significant contributions to the '47 design, would head Loewy's South Bend studio into 1955, after which Studebaker and Loewy parted company.
People loved the 1947 Studebakers, the little-changed '48s, and the modestly updated '49s. Though the fresh styling concealed mostly prewar mechanical concepts, refinements were made to improve longevity and reliability.

+++ DISCLAIMER +++
Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
The Nakajima J9N Kitsuka (中島 橘花, "Orange Blossom", pronounced Kikka in Kanji used traditionally by the Japanese) was Japan's first jet aircraft. In internal IJN documents it was also called Kōkoku Nigō Heiki (皇国二号兵器, "Imperial Weapon No.2"). After the Japanese military attaché in Germany witnessed trials of the Messerschmitt Me 262 in 1942, the Imperial Japanese Navy issued a request to Nakajima to develop a similar aircraft to be used as a fast attack bomber. Among the specifications for the design were the requirements that it should be able to be built largely by unskilled labor, and that the wings should be foldable. This latter feature was not intended for potential use on aircraft carriers, but rather to enable the aircraft to be hidden in caves and tunnels around Japan as the navy began to prepare for the defense of the home islands.
Nakajima designers Kazuo Ohno and Kenichi Matsumura laid out an aircraft that bore a strong but superficial resemblance to the Me 262. Compared to the Me 262, the J9N airframe was noticeably smaller and more conventional in design, with straight wings (lacking the slight sweepback of the Me 262) and tail surfaces. The triangular fuselage cross section characteristic of the German design was less pronounced, due to smaller fuel tanks. The main landing gear of the Kikka was taken from the A6M Zero and the nose wheel from the tail of a Yokosuka P1Y bomber.
The Kikka was designed in preliminary form to use the Tsu-11, a rudimentary motorjet style jet engine that was essentially a ducted fan with an afterburner. Subsequent designs were planned around the Ne-10 (TR-10) centrifugal-flow turbojet, and the Ne-12, which added a four-stage axial compressor to the front of the Ne-10. Tests of this powerplant soon revealed that it would not produce anywhere near the power required to propel the aircraft, and the project was temporarily stalled. It was then decided to produce a new axial flow turbojet based on the German BMW 003.
Development of the engine was troubled, based on little more than photographs and a single cut-away drawing of the BMW 003. A suitable unit, the Ishikawa-jima Ne-20, was finally built in January 1945. By that time, the Kikka project was making progress and the first prototype made its maiden flight. Due to the worsening war situation, the Navy considered employing the Kikka as a kamikaze weapon, but this was quickly rejected due to the high cost and complexity associated with manufacturing contemporary turbojet engines. Other more economical projects designed specifically for kamikaze attacks, such as the simpler Nakajima Tōka (designed to absorb Japanese stock of obsolete engines), the pulsejet-powered Kawanishi Baika, and the infamous Yokosuka Ohka, were either underway or already in mass production.
The following month the prototype was dismantled and delivered to Kisarazu Naval Airfield where it was re-assembled and prepared for flight testing. The aircraft performed well during a 20-minute test flight, with the only concern being the length of the takeoff run – the Ne 20 only had a thrust of 4.66 kN (1,047 lbf), and the engine pair had barely sufficient power to get the aircraft off the ground. This lack of thrust also resulted in a maximum speed of just 623 km/h (387 mph, 336 kn) at sea level and 696 km/h (432 mph; 376 kn) at 10,000 m (32,808 ft).
For the second test flight, four days later, rocket assisted take off (RATO) units were fitted to the aircraft, which worked and gave the aircraft acceptable field performance. The tests went on, together with a second prototype, but despite this early test stage, the J9N was immediately rushed into production.
By May 1945 approximately forty airframes had been completed and handed over to IJN home defense frontline units for operational use and conversion training. These were structurally identical with the prototypes, but they were powered by more potent and reliable Ne-130 (with 8.826 kN/900 kgf) or Ne-230 (8.679 kN/885 kg) engines, which finally gave the aircraft a competitive performance and also made the RATO boosters obsolete - unless an 800 kg bomb was carried in overload configuration. Most of them were J9N1 day fighter single seaters, armed with two 30 mm Type 5 cannons with 50 rounds per gun in the nose, but a few were unarmed two-seaters (J9N2) with dual controls and a second seat instead of the fuselage fuel tank, what markedly limited the aircraft’s range but was accepted for a trainer.
Some operational Kitsukas also had, due to the lack of equipment, the 30 mm guns replaced with lighter 20 mm Ho-5 cannon. A small number, both single- and two-seaters, were also equipped with an experimental centimeter waveband FD-2 radar in the nose with an “antler” antenna array, similar to German radar sets of the time. In order to fit the electronics, the machines typically had one of the nose-mounted guns replaced by a fixed, obliquely firing Ho-5 gun ("Schräge Musik"-style) behind the cockpit. These machine received the suffix “-S” and flew a few quite effective missions against American B-29 bombers, but their impact was minimal due to the aircrafts’ small numbers and poor reliability of the still experimental radar system.
Proposed follow-on versions had included a reconnaissance aircraft and a fast attack aircraft that was supposed to carry a single bomb under the fuselage against ships. There was also a modified version of the design to be launched from a 200 m long catapult, the "Nakajima Kikka-kai Prototype Turbojet Special Attacker". All these proposed versions were expected to be powered by more advanced developments of the Ne-20, the Ne-330 with 13 kN (1.330 kg) thrust, but none of them reached the hardware stage.
The J9Ns’ war contribution was negligible, and after the war, several airframes (including partial airframes) were captured by Allied forces. Three airframes (including a two-seat night fighter with FD-2 radar) were brought to the U.S. for study, two damaged day fighters were handed over to the RAF and transferred to RAF Seletar, where the airframes were, together with spares, combined into a single flyworthy J9N1 designated “FE (Foreign Equipment) 269” and tested by the Allied Technical Air Intelligence Unit. These tests did not last long, though, because the engines were in poor condition and only lasted for four test flights until one failed fatally and caused a fire: at least one compressor blade had separated and ruptured fuel and oil lines. The pilot was able to leave the burning and disintegrating aircraft but was hit by the tail and was badly injured. However, he survived, but FE 269 crashed into the Street of Sohor.
Today, two J9N examples survive in the National Air and Space Museum: The first is a Kikka that was taken to the Patuxent River Naval Air Base, Maryland for analysis. This aircraft is very incomplete and is believed to have been patched together from a variety of semi-completed airframes. It is currently still in storage at the Paul E. Garber Preservation, Restoration and Storage Facility in Silver Hill, MD.
The second Kikka is on display at the NASM Udvar-Hazy Center in the Mary Baker Engen Restoration Hangar.

The kit and its assembly:
This is submission #4 for the “Captured!” group build at whatifmodellers.com in late 2020. Loot from WWII certainly makes a good theme, and I remembered a real world J2M3 that I had built some time ago – in RAF markings and tested by the ATAIU-SEA in Singapore in late the 1945. For a more whiffy touch I delved through The Stash™ for options and found an AZ Models Nakajima “Kikka” single seater – as Japan’s first jet fighter, a suitable contender, even more so because no aircraft of this type made it in time to frontline units.
The AZ Models kit is a simple affair, but that's also its problem. In the box things looked quite good, detail level is on par with a classic Matchbox kit. But unlike a Matchbox kit, the AZ Models offering does not go together... I had to fight everywhere with poor fit, lack of locator pins, ejection marks - anything a short run model kit can throw at you! Things turned out really bad: One upper wing half was bent so much that I tried to counter the flaw with force - and the part broke! Furthermore, PSR was necessary almost everywhere – but especially around the wing/engine pod intersection and the area where the wings are inserted into the fuselage. Huh! What worked surprisingly well is the IP canopy, though.
Personal additions are lowered flaps (easy to realize) and some additional struts for the landing gear.
Painting and markings:
The captured aircraft theme was settled from the start, but I wanted to offer more than just a “rebadging” with RAF roundels on an IJN green/grey airframe. In order to add some visual spice, my idea became to present an irregular "one-aircraft-made-from-two-wrecks" finish, with parts in differing tones and even some primed or bare metal areas.
I gave the model an overall coat of aluminum (with Red Stars added, this would have made another interesting whif!) and started adding cloudy shades of IJN Green (ModelMaster and Tamiya) and sections with RAF Dark Green to the upper surfaces, and light grey underneath, with the aluminum underneath shining through here and there. One engine was furthermore painted in a shaggy Japanese primer red brown. I furthermore added overpainted IJN markings with U.S. olive drab for some more contrast, even though would later be at least partly hidden under decals.
The cockpit was painted in a greenish yellow primer (trying to simulate a typical “bamboo” shade that was used in some late-war IJN cockpits), while the landing gear and the flaps’ interior was painted in dull aluminum (Humbrol 56).
A black ink washing was applied for more weathering and contrast. the yellow leading edge markings were created with decal material. RAF roundels came from the scrap box, the “FE 269” code was created with single white 3mm letters. The “ATAIU-SEA” titles were painted with a thin brush and white acrylic paint, and sanded down a bit once dry, for a weathered look.
Finally, the kit received a mixed coat of semi-gloss and matt acrylic varnish.
I had the Kikka earmarked for a different build, but I think this ATAIU livery adds an interesting twist to the model, it looks pretty plausible. Besides, the Kitsuka is a pretty, elegant aircraft, and it's relatively small (even petit) when compared with a contemporary Me 262 or a Meteor!
