A wrecking yard (Australian, New Zealand, and Canadian English), scrapyard (Irish and British English) or junkyard (American English) is the location of a business in dismantling where wrecked or decommissioned vehicles are brought, their usable parts are sold for use in operating vehicles, while the unusable metal parts, known as scrap metal parts, are sold to metal-recycling companies.
Other terms include wreck yard, wrecker's yard, salvage yard, breakers yard, dismantler and scrapheap. In the United Kingdom, car salvage yards are known as car breakers, while motorcycle salvage yards are known as bike breakers. In Australia, they are often referred to as 'Wreckers'.
The most common type of wreck yards are automobile wreck yards, but junkyards for motorcycles, bicycles, small airplanes and boats exist too.
Many salvage yards operate on a local level—when an automobile is severely damaged, has malfunctioned beyond repair, or not worth the repair, the owner may sell it to a junkyard; in some cases—as when the car has become disabled in a place where derelict cars are not allowed to be left—the car owner will pay the wrecker to haul the car away.
Salvage yards also buy most of the wrecked, derelict and abandoned vehicles that are sold at auction from police impound storage lots,and often buy vehicles from insurance tow yards as well.
The salvage yard will usually tow the vehicle from the location of its purchase to the yard, but occasionally vehicles are driven in. At the salvage yard the automobiles are typically arranged in rows, often stacked on top of one another.
Some yards keep inventories in their offices, as to the usable parts in each car, as well as the car's location in the yard. Many yards have computerized inventory systems. About 75% of any given vehicle can be recycled and used for other goods.
In recent years it is becoming increasingly common to use satellite part finder services to contact multiple salvage yards from a single source.
In the 20th century these were call centres that charged a premium rate for calls and compiled a facsimile that was sent to various salvage yards so they could respond directly if the part was in stock. Many of these are now Web-based with requests for parts being e-mailed instantly.

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the Joint Strike Fighter (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.
We recently visited the USS Alabama Battleship Memorial Park. In addition to the amazing battleship there are many military airplanes on display. I was absolutely fascinated with the SR-71 Blackbird. Visually and operationally, this is an extraordinary aircraft! I was inspired to honor it by creating a series of photo-art pieces. In these pictures, the photos of the SR-71 were taken by me; either of the airplane on display at the park or a model airplane which I bought. The aerial shots of the earth were downloaded from NASA's website.
Interesting info about this beautiful bird:
The SR-71 reconnaissance aircraft flew missions at speeds beyond 2,000 mph and could survey the ground from 80,000 feet!! This extreme height allowed the aircraft to avoid interceptor fighter jets or missiles. The SR-71 is covered with a special black paint to absorb radar and camouflage the bird against dark skies, which inspired the Air Force to give it the official "Blackbird" name. To withstand the friction-generated heat at Mach 3+, the frame is made of titanium composite and the tires have been impregnated with aluminum and are filled with nitrogen. In the 1960s when this plane was built, computerized equipment was non-existent, thus the cockpit and flight systems were all analog.
A total of 3,551 mission sorties were flown to spy on military installations, troop movements and nuclear silos during the cold war.
The use of satellites for space surveillance and the growing danger of more effective air defense caused the Air Force to end SR-71 operations in 1990. On it's last flight it set a speed record by flying from Los Angeles to Washington DC in 1 hour, 4 minutes, 20 seconds!

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 OV-10 Bronco was initially conceived in the early 1960s through an informal collaboration between W. H. Beckett and Colonel K. P. Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.
The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.
Beckett and Rice developed a basic platform meeting these requirements, then attempted to build a fiberglass prototype in a garage. The effort produced enthusiastic supporters and an informal pamphlet describing the concept. W. H. Beckett, who had retired from the Marine Corps, went to work at North American Aviation to sell the aircraft.
The aircraft's design supported effective operations from forward bases. The OV-10 had a central nacelle containing a crew of two in tandem and space for cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connected them at the fin tips. The OV-10 could perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.
The aircraft had responsive handling and could fly for up to 5½ hours with external fuel tanks. The cockpit had extremely good visibility for both pilot and co-pilot, provided by a wrap-around "greenhouse" that was wider than the fuselage. North American Rockwell custom ejection seats were standard, with many successful ejections during service. With the second seat removed, the OV-10 could carry 3,200 pounds (1,500 kg) of cargo, five paratroopers, or two litter patients and an attendant. Empty weight was 6,969 pounds (3,161 kg). Normal operating fueled weight with two crew was 9,908 pounds (4,494 kg). Maximum takeoff weight was 14,446 pounds (6,553 kg).
The bottom of the fuselage bore sponsons or "stub wings" that improved flight performance by decreasing aerodynamic drag underneath the fuselage. Normally, four 7.62 mm (.308 in) M60C machine guns were carried on the sponsons, accessed through large forward-opening hatches. The sponsons also had four racks to carry bombs, pods, or fuel. The wings outboard of the engines contained two additional hardpoints, one per side. Racked armament in the Vietnam War was usually seven-shot 2.75 in (70 mm) rocket pods with white phosphorus marker rounds or high-explosive rockets, or 5" (127 mm) four-shot Zuni rocket pods. Bombs, ADSIDS air-delivered/para-dropped unattended seismic sensors, Mk-6 battlefield illumination flares, and other stores were also carried.
Operational experience showed some weaknesses in the OV-10's design. It was significantly underpowered, which contributed to crashes in Vietnam in sloping terrain because the pilots could not climb fast enough. While specifications stated that the aircraft could reach 26,000 feet (7,900 m), in Vietnam the aircraft could reach only 18,000 feet (5,500 m). Also, no OV-10 pilot survived ditching the aircraft.
The OV-10 served in the U.S. Air Force, U.S. Marine Corps, and U.S. Navy, as well as in the service of a number of other countries. In U.S. military service, the Bronco was operated until the early Nineties, and obsoleted USAF OV-10s were passed on to the Bureau of Alcohol, Tobacco, and Firearms for anti-drug operations. A number of OV-10As furthermore ended up in the hands of the California Department of Forestry (CDF) and were used for spotting fires and directing fire bombers onto hot spots.
This was not the end of the OV-10 in American military service, though: In 2012, the type gained new attention because of its unique qualities. A $20 million budget was allocated to activate an experimental USAF unit of two airworthy OV-10Gs, acquired from NASA and the State Department. These machines were retrofitted with military equipment and were, starting in May 2015, deployed overseas to support Operation “Inherent Resolve”, flying more than 120 combat sorties over 82 days over Iraq and Syria. Their concrete missions remained unclear, and it is speculated they provided close air support for Special Forces missions, esp. in confined urban environments where the Broncos’ loitering time and high agility at low speed and altitude made them highly effective and less vulnerable than helicopters.
Furthermore, these Broncos reputedly performed strikes with the experimental AGR-20A “Advanced Precision Kill Weapons System (APKWS)”, a Hydra 70-millimeter rocket with a laser-seeking head as guidance - developed for precision strikes against small urban targets with little collateral damage. The experiment ended satisfactorily, but the machines were retired again, and the small unit was dissolved.
However, the machines had shown their worth in asymmetric warfare, and the U.S. Air Force decided to invest in reactivating the OV-10 on a regular basis, despite the overhead cost of operating an additional aircraft type in relatively small numbers – but development and production of a similar new type would have caused much higher costs, with an uncertain time until an operational aircraft would be ready for service. Re-activating a proven design and updating an existing airframe appeared more efficient.
The result became the MV-10H, suitably christened “Super Bronco” but also known as “Black Pony”, after the program's internal name. This aircraft was derived from the official OV-10X proposal by Boeing from 2009 for the USAF's Light Attack/Armed Reconnaissance requirement. Initially, Boeing proposed to re-start OV-10 manufacture, but this was deemed uneconomical, due to the expected small production number of new serial aircraft, so the “Black Pony” program became a modernization project. In consequence, all airframes for the "new" MV-10Hs were recovered OV-10s of various types from the "boneyard" at Davis-Monthan Air Force Base in Arizona.
While the revamped aircraft would maintain much of its 1960s-vintage rugged external design, modernizations included a completely new, armored central fuselage with a highly modified cockpit section, ejection seats and a computerized glass cockpit. The “Black Pony” OV-10 had full dual controls, so that either crewmen could steer the aircraft while the other operated sensors and/or weapons. This feature would also improve survivability in case of incapacitation of a crew member as the result from a hit.
The cockpit armor protected the crew and many vital systems from 23mm shells and shrapnel (e. g. from MANPADS). The crew still sat in tandem under a common, generously glazed canopy with flat, bulletproof panels for reduced sun reflections, with the pilot in the front seat and an observer/WSO behind. The Bronco’s original cargo capacity and the rear door were retained, even though the extra armor and defensive measures like chaff/flare dispensers as well as an additional fuel cell in the central fuselage limited the capacity. However, it was still possible to carry and deploy personnel, e. g. small special ops teams of up to four when the aircraft flew in clean configuration.
Additional updates for the MV-10H included structural reinforcements for a higher AUW and higher g load maneuvers, similar to OV-10D+ standards. The landing gear was also reinforced, and the aircraft kept its ability to operate from short, improvised airstrips. A fixed refueling probe was added to improve range and loiter time.
Intelligence sensors and smart weapon capabilities included a FLIR sensor and a laser range finder/target designator, both mounted in a small turret on the aircraft’s nose. The MV-10H was also outfitted with a data link and the ability to carry an integrated targeting pod such as the Northrop Grumman LITENING or the Lockheed Martin Sniper Advanced Targeting Pod (ATP). Also included was the Remotely Operated Video Enhanced Receiver (ROVER) to provide live sensor data and video recordings to personnel on the ground.
To improve overall performance and to better cope with the higher empty weight of the modified aircraft as well as with operations under hot-and-high conditions, the engines were beefed up. The new General Electric CT7-9D turboprop engines improved the Bronco's performance considerably: top speed increased by 100 mph (160 km/h), the climb rate was tripled (a weak point of early OV-10s despite the type’s good STOL capability) and both take-off as well as landing run were almost halved. The new engines called for longer nacelles, and their circular diameter markedly differed from the former Garrett T76-G-420/421 turboprop engines. To better exploit the additional power and reduce the aircraft’s audio signature, reversible contraprops, each with eight fiberglass blades, were fitted. These allowed a reduced number of revolutions per minute, resulting in less noise from the blades and their tips, while the engine responsiveness was greatly improved. The CT7-9Ds’ exhausts were fitted with muzzlers/air mixers to further reduce the aircraft's noise and heat signature.
Another novel and striking feature was the addition of so-called “tip sails” to the wings: each wingtip was elongated with a small, cigar-shaped fairing, each carrying three staggered, small “feather blade” winglets. Reputedly, this installation contributed ~10% to the higher climb rate and improved lift/drag ratio by ~6%, improving range and loiter time, too.
Drawing from the Iraq experience as well as from the USMC’s NOGS test program with a converted OV-10D as a night/all-weather gunship/reconnaissance platform, the MV-10H received a heavier gun armament: the original four light machine guns that were only good for strafing unarmored targets were deleted and their space in the sponsons replaced by avionics. Instead, the aircraft was outfitted with a lightweight M197 three-barrel 20mm gatling gun in a chin turret. This could be fixed in a forward position at high speed or when carrying forward-firing ordnance under the stub wings, or it could be deployed to cover a wide field of fire under the aircraft when it was flying slower, being either slaved to the FLIR or to a helmet sighting auto targeting system.
The original seven hardpoints were retained (1x ventral, 2x under each sponson, and another pair under the outer wings), but the total ordnance load was slightly increased and an additional pair of launch rails for AIM-9 Sidewinders or other light AAMs under the wing tips were added – not only as a defensive measure, but also with an anti-helicopter role in mind; four more Sidewinders could be carried on twin launchers under the outer wings against aerial targets. Other guided weapons cleared for the MV-10H were the light laser-guided AGR-20A and AGM-119 Hellfire missiles, the Advanced Precision Kill Weapon System upgrade to the light Hydra 70 rockets, the new Laser Guided Zuni Rocket which had been cleared for service in 2010, TV-/IR-/laser-guided AGM-65 Maverick AGMs and AGM-122 Sidearm anti-radar missiles, plus a wide range of gun and missile pods, iron and cluster bombs, as well as ECM and flare/chaff pods, which were not only carried defensively, but also in order to disrupt enemy ground communication.
In this configuration, a contract for the conversion of twelve mothballed American Broncos to the new MV-10H standard was signed with Boeing in 2016, and the first MV-10H was handed over to the USAF in early 2018, with further deliveries lasting into early 2020. All machines were allocated to the newly founded 919th Special Operations Support Squadron at Duke Field (Florida). This unit was part of the 919th Special Operations Wing, an Air Reserve Component (ARC) of the United States Air Force. It was assigned to the Tenth Air Force of Air Force Reserve Command and an associate unit of the 1st Special Operations Wing, Air Force Special Operations Command (AFSOC). If mobilized the wing was gained by AFSOC (Air Force Special Operations Command) to support Special Tactics, the U.S. Air Force's special operations ground force. Similar in ability and employment to Marine Special Operations Command (MARSOC), U.S. Army Special Forces and U.S. Navy SEALs, Air Force Special Tactics personnel were typically the first to enter combat and often found themselves deep behind enemy lines in demanding, austere conditions, usually with little or no support.
The MV-10Hs are expected to provide support for these ground units in the form of all-weather reconnaissance and observation, close air support and also forward air control duties for supporting ground units. Precision ground strikes and protection from enemy helicopters and low-flying aircraft were other, secondary missions for the modernized Broncos, which are expected to serve well into the 2040s. Exports or conversions of foreign OV-10s to the Black Pony standard are not planned, though.

The kit and its assembly:
This fictional Bronco update/conversion was simply spawned by the idea: could it be possible to replace the original cockpit section with one from an AH-1 Cobra, for a kind of gunship version?
The basis is the Academy OV-10D kit, mated with the cockpit section from a Fujimi AH-1S TOW Cobra (Revell re-boxing, though), chosen because of its “boxy” cockpit section with flat glass panels – I think that it conveys the idea of an armored cockpit section best. Combining these parts was not easy, though, even though the plan sound simple. Initially, the Bronco’s twin booms, wings and stabilizer were built separately, because this made PSR on these sections easier than trying the same on a completed airframe. One of the initial challenges: the different engines. I wanted something uprated, and a different look, and I had a pair of (excellent!) 1:144 resin engines from the Russian company Kompakt Zip for a Tu-95 bomber at hand, which come together with movable(!) eight-blade contraprops that were an almost perfect size match for the original three-blade props. Biggest problem: the Tu-95 nacelles have a perfectly circular diameter, while the OV-10’s booms are square and rectangular. Combining these parts and shapes was already a messy PST affair, but it worked out quite well – even though the result rather reminds of some Chinese upgrade measure (anyone know the Tu-4 copies with turboprops? This here looks similar!). But while not pretty, I think that the beafier look works well and adds to the idea of a “revived” aircraft. And you can hardly beat the menacing look of contraprops on anything...
The exotic, so-called “tip sails” on the wings, mounted on short booms, are a detail borrowed from the Shijiazhuang Y-5B-100, an updated Chinese variant/copy of the Antonov An-2 biplane transporter. The booms are simple pieces of sprue from the Bronco kit, the winglets were cut from 0.5mm styrene sheet.
For the cockpit donor, the AH-1’s front section was roughly built, including the engine section (which is a separate module, so that the basic kit can be sold with different engine sections), and then the helicopter hull was cut and trimmed down to match the original Bronco pod and to fit under the wing. This became more complicated than expected, because a) the AH-1 cockpit and the nose are considerably shorter than the OV-10s, b) the AH-1 fuselage is markedly taller than the Bronco’s and c) the engine section, which would end up in the area of the wing, features major recesses, making the surface very uneven – calling for massive PSR to even this out. PSR was also necessary to hide the openings for the Fujimi AH-1’s stub wings. Other issues: the front landing gear (and its well) had to be added, as well as the OV-10 wing stubs. Furthermore, the new cockpit pod’s rear section needed an aerodynamical end/fairing, but I found a leftover Academy OV-10 section from a build/kitbashing many moons ago. Perfect match!
All these challenges could be tackled, even though the AH-1 cockpit looks surprisingly stout and massive on the Bronco’s airframe - the result looks stockier than expected, but it works well for the "Gunship" theme. Lots of PSR went into the new central fuselage section, though, even before it was mated with the OV-10 wing and the rest of the model.
Once cockpit and wing were finally mated, the seams had to disappear under even more PSR and a spinal extension of the canopy had to be sculpted across the upper wing surface, which would meld with the pod’s tail in a (more or less) harmonious shape. Not an easy task, and the fairing was eventually sculpted with 2C putty, plus even more PSR… Looks quite homogenous, though.
After this massive body work, other hardware challenges appeared like small distractions. The landing gear was another major issue because the deeper AH-1 section lowered the ground clearance, also because of the chin turret. To counter this, I raised the OV-10’s main landing gear by ~2mm – not much, but it was enough to create a credible stance, together with the front landing gear transplant under the cockpit, which received an internal console to match the main landing gear’s length. Due to the chin turret and the shorter nose, the front wheel retracts backwards now. But this looks quite plausible, thanks to the additional space under the cockpit tub, which also made a belt feed for the gun’s ammunition supply believable.
To enhance the menacing look I gave the model a fixed refueling boom, made from 1mm steel wire and a receptor adapter sculpted with white glue. The latter stuff was also used add some antenna fairings around the hull. Some antennae, chaff dispensers and an IR decoy were taken from the Academy kit.
The ordnance came from various sources. The Sidewinders under the wing tips were taken from an Italeri F-16C/D kit, they look better than the missiles from the Academy Bronco kit. Their launch rails came from an Italeri Bae Hawk 200. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-10 and -19 missile pods on the stub wings were taken from the OV-10 kit.
Painting and markings:
Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 (suitably “Gunship Gray” :D) from above, FS 36375 underneath, with a low, wavy waterline, plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s.
The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).
The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth was taken from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.
Decals were also used to create the trim on the propeller blades and markings on the ordnance.
Finally, the model was sealed with a coat of matt acrylic varnish (Italeri) and some exhaust soot stains were added with graphite along the tail boom flanks.
A successful transplantation – but is this still a modified Bronco or already a kitbashing? The result looks quite plausible and menacing, even though the TOW Cobra front section appears relatively massive. But thanks to the bigger engines and extended wing tips the proportions still work. The large low-pressure tires look a bit goofy under the aircraft, but they are original. The grey livery works IMHO well, too – a more colorful or garish scheme would certainly have distracted from the modified technical basis.

Southeast Financial Center is a two-acre development in Miami, Florida, United States. It consists of a 764 feet (233 m) tall office skyscraper and its 15-story parking garage. It was previously known as the Southeast Financial Center (1984–1992), the First Union Financial Center (1992–2003), and the Wachovia Financial Center (2003-2011). In 2011, it retook its old name of Southeast Financial Center as Wachovia merged with Wells Fargo and moved to the nearby Wells Fargo Center.
When topped-off in August 1983, it was the tallest building south of New York City and east of the Mississippi River, taking away the same title from the Westin Peachtree Plaza Hotel, in Atlanta, Georgia. It remained the tallest building in the southeastern U.S. until 1987, when it was surpassed by One Atlantic Center in Atlanta and the tallest in Florida until October 1, 2003, when it was surpassed by the Four Seasons Hotel and Tower, also in Miami. It remains the tallest office tower in Florida and the third tallest building in Miami.
Southeast Financial Center was constructed in three years with more than 500 construction workers. Approximately 6,650 tons of structural steel, 80,000 cubic yards of concrete and 7000 cubic tons of reinforcing steel bars went into its construction. The complex sits on a series of reinforced concrete grade beams tied to 150 concrete caissons as much as ten feet in diameter and to a depth of 80 feet. A steel space-frame canopy with glass skylights covers the outdoor plaza between the tower and low-rise building.
The tower has a composite structure. The exterior columns and beams are concrete encased steel wide flanges surrounded by reinforcing bars. The composite exterior frame was formed using hydraulic steel forms, or "flying forms," jacked into place with a "kangaroo" crane, that was located in the core and manually clamped into place. Wide flange beams topped by a metal deck and concrete form the interior floor framing. The core is A braced steel frame, designed to laterally resist wind loads. The construction of one typical floor was completed every five days.
The low-rise banking hall and parking building is a concrete-framed structure. Each floor consists of nearly an acre of continuously poured concrete. When the concrete had sufficiently hardened, compressed air was used to blow the forms fiberglass forms from under the completed floor. It was then rolled out to the exterior where it was raised by crane into position for the next floor.
The building was recognized as Miami's first and only office building to be certified for the LEED Gold award in January 2010.
The center was developed by a partnership consisting of Gerald D. Hines Interests, Southeast Bank and Corporate Property Investors for $180 million. It was originally built as the headquarters for Southeast Bank, which originally occupied 50 percent of the complex's space. It remained Southeast Bank's headquarters there until it was liquidated in 1991.
The Southeast Financial Center comprises two buildings: the 55-story office tower and the 15-story parking annex. The tower has 53 stories of office space. The first floor is dedicated for retail, the second floor is the lobby and the 55th floor was home to the luxurious Miami City Club. The parking annex has 12 floors of parking space for 1,150 cars. The first floor is dedicated for retail, the second floor is a banking hall and the 15th floor has the Downtown Athletic Club. A landscaped plaza lies between the office tower and the parking annex. An enclosed walkway connects the second story of the tower with the second story of the annex. The courtyard is partially protected from the elements by a steel and glass space frame canopy spanning the plaza and attached to the tower and annex. Southeast Bank's executive offices were located on the 38th floor. Ground was broken on the complex on December 12, 1981 and the official dedication and opening for the complex was held on October 23, 1984.
The Southeast Financial Center was designed by Edward Charles Bassett of Skidmore, Owings and Merrill. The Associate Architect was Spillis Candela & Partners. It has 1,145,311 ft² (106,000 m²) of office space. A typical floor has about 22,000 ft² (2,043.87 m²) of office space. Each floor has 9 ft x 9 ft (2.7 m x 2.7 m) floor to ceiling windows. (All of the building's windows are tinted except for the top floor, resulting in strikingly bright and clear views from there.) The total complex has over 2.2 million ft² (204,000 m²). The distinctive setbacks begin at the 43rd floor. Each typical floor plate has 9 corner offices and the top twelve floors have as many as 16. There are 43 elevators in the office tower. An emergency control station provides computerized monitoring for the entire complex, and four generators for backup power.
The Southeast Financial Center can be seen as far away as Ft. Lauderdale and halfway toward Bimini. Night space shuttle launches from Cape Canaveral 200 miles to the north were plainly visible from the higher floors. The roof of the building was featured in the Wesley Snipes motion picture Drop Zone, where an eccentric base jumper named Swoop parachutes down to the street from a suspended window cleaning trolley. The building also appeared in several episodes of the 1980s TV show Miami Vice and at the end of each episode's opening credits.
Zara founder Amancio Ortega purchased the building from J.P. Morgan Asset Management in December 2016. The purchase price was reportedly over $500 million, making it one of the largest real estate transactions in South Florida history.

‘Crew One,’ a three-man weapons load team, completes the first full external loadout with live munitions for the Lockheed Martin F-35A Lightening II May 3, 2019, at Al Dhafra Air Base, United Arab Emirates. Lockheed Martin F-35A Lightning IIs assigned to the 4th Expeditionary Fighter Squadron were configured in a full external live loadout of six GBU-49 small glide munitions and two AIM-9x Sidewinder missiles to execute an operation in Southwest Asia.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the Joint Strike Fighter (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.

Nothing you see here is real, even though the model, the conversion or the presented background story might be based historical facts. BEWARE!
Some background:
The Georgian Air Force and Air Defense Division (თავდაცვის ძალების ავიაციისა და საჰაერო თავდაცვის სარდლობა; tavdatsvis dzalebis aviatsiisa da sahaero tavdatsvis sardloba) was established on January 1, 1992, and in September the Georgian Air Force conducted its first combat flight during the separatist war in Abkhazia. On August 18, 1998, the two divisions were unified in a joint command structure and renamed the Georgian Air Force.
In 2010, the Georgian Air Force was abolished as a separate branch and incorporated into the Georgian Land Forces as Air and Air Defense sections. By that time, the equipment – primarily consisting of Eastern Bloc aircraft inherited from the Soviet Union after the country’s dissolution – was totally outdated, the most potent aircraft were a dozen Suchoj Su-25 attack aircraft and a handful of MiG-21U trainers.
In order to rejuvenate the air arm, Tbilisi Aircraft Manufacturing (TAM), also known as JSC Tbilaviamsheni and formerly known as 31st aviation factory, started a modernization program for the Su-25, for the domestic forces but also for export customers. TAM had a long tradition of aircraft production within the Soviet Union. In the 1950s the factory started the production of Mikoyan's MiG-15 and later, the MiG-17 fighter aircraft. In 1957 Tbilisi Aircraft State Association built the MiG-21 two-seater fighter-trainer aircraft and its various derivative aircraft, continuing the MiG-21 production for about 25 years. At the same time the company was manufacturing the K-10 air-to-surface guided missile. Furthermore, the first Sukhoi Su-25 (known in the West as the "Frogfoot") close support aircraft took its maiden voyage from the runway of 31st aviation factory. Since then, more than 800 SU-25s had been delivered to customers worldwide. From the first SU-25 to the 1990s, JSC Tbilaviamsheni was the only manufacturer of this aircraft, and even after the fall of the Soviet Union the production lines were still intact and spares for more than fifty complete aircraft available. Along with the SU-25 aircraft 31st aviation factory also launched large-scale production of air-to-air R-60 and R-73 IR guided missiles, a production effort that built over 6,000 missiles a year and that lasted until the early 1990s. From 1996 to 1998 the factory also produced Su-25U two-seaters.
In 2001 the factory started, in partnership with Elbit Systems of Israel, upgrading basic Su-25 airframes to the Su-25KM “Scorpion” variant. This was just a technical update, however, intended for former Su-25 export customers who would upgrade their less potent Su-25K export aircraft with modern avionics. The prototype aircraft made its maiden flight on 18 April 2001 at Tbilisi in full Georgian Air Force markings. The aircraft used a standard Su-25 airframe, enhanced with advanced avionics including a glass cockpit, digital map generator, helmet-mounted display, computerized weapons system, complete mission pre-plan capability, and fully redundant backup modes. Performance enhancements included a highly accurate navigation system, pinpoint weapon delivery systems, all-weather and day/night performance, NATO compatibility, state-of-the art safety and survivability features, and advanced onboard debriefing capabilities complying with international requirements. The Su-25KM had the ability to use NATO-standard Mark 82 and Mark 83 laser-guided bombs and new air-to-air missiles, the short-range Vympel R-73. This upgrade extended service life of the Su-25 airframes for another decade.
There were, however, not many customers. Manufacturing was eventually stopped at the end of 2010, after Georgian air forces have been permanently dismissed and abolished. By that time, approximately 12 Scorpions had been produced, but the Georgian Air Force still used the basic models of Su-25 because of high cost of Su-25KM and because it was destined mainly for export. According to unofficial sources several Scorpions had been transferred to Turkmenistan as part of a trade deal.
In the meantime, another, more ambitious project took shape at Tbilisi Aircraft Manufacturing, too: With the help of Israel Aircraft Industries (IAI) the company started the development of a completely new attack aircraft, the TAM-1 “Gvelgeslas” (გველგესლას, Viper). It heavily relied on the year-long experience gathered with Su-25 production at Tblisi and on the tools at hand, but it was eventually a completely new aircraft – looking like a crossbreed between the Su-25 and the American A-10 with a T-tail.
This new layout had become necessary because the aircraft was to be powered by more modern, less noisy and more fuel-efficient Rolls Royce AE 3012 turbofan engines - which were originally intended to power the stillborn Yakovlev Yak-77 twin-engine business jet for up to 32 passengers, a slightly derated variant of the GMA 3012 with a 44 in diameter (112 cm) fan and procured via IAI from the United States through the company’s connection with Gulfstream Aerospace. Their larger diameter (the Su-25’s original Soyuz/Tumansky R-195 turbojets had a diameter of 109,5 cm/43.1 in) precluded the use of the former integral engine nacelles along the fuselage. To keep good ground clearance against FOD and to protect them from small arms fire, the engine layout was completely re-arranged. The fuselage was streamlined, and its internal structure was totally changed. The wings moved into a low position. The wings’ planform was almost identical to the Su-25’s, together with the characteristic tip-mounted “crocodile” air brakes. Just the leading edge inside of the “dogteeth” and the wing roots were re-designed, the latter because of the missing former engine nacelles. This resulted in a slightly increased net area, the original wingspan was retained. The bigger turbofans were then mounted in separate pods on short pylons along the rear fuselage, partly protected from below by the wings. Due to the jet efflux and the engines’ proximity to the stabilizers, these were re-located to the top of a deeper, reinforced fin for a T-tail arrangement.
Since the Su-25’s engine bays were now gone, the main landing gear had to be completely re-designed. Retracting them into the fuselage or into the relatively thin wings was not possible, TAM engineers settled upon a design that was very similar to the A-10: the aircraft received streamlined fairings, attached to the wings’ main spar, and positioned under the wings’ leading edges. The main legs were only semi-retractable; in flight, the wheels partly protruded from the fairings, but that hardly mattered from an aerodynamic point of view at the TAM-1’s subsonic operational speed. As a bonus they could still be used while retracted during emergency landings, improving the aircraft’s crash survivability.
Most flight and weapon avionics were procured from or via Elbit, including the Su-25KT’s modernized “glass cockpit”, and the TAM-1’s NATO compatibility was enhanced to appeal to a wider international export market. Beyond a total of eleven hardpoints under the wings and the fuselage for an external ordnance of up to 4.500 kg (9.900 lb), the TAM-1 was furthermore armed with an internal gun. Due to procurement issues, however, the Su-25’s original twin-barrel GSh-30-2 was replaced with an Oerlikon KDA 35mm cannon – a modern variant of the same cannon used in the German Gepard anti-aircraft tank, adapted to the use in an aircraft with a light-weight gun carriage. The KDA gun fired with a muzzle velocity of 1,440 m/s (4,700 ft/s) and a range of 5.500m, its rate of fire was typically 550 RPM. For the TAM-1, a unique feature from the SPAAG installation was adopted: the gun had two magazines, one with space for 200 rounds and another, smaller one for 50. The magazines could be filled with different types of ammunition, and the pilot was able select between them with a simple switch, adapting to the combat situation. Typical ammunition types were armor-piercing FAPDS rounds against hardened ground targets like tanks, and high explosive shells against soft ground targets and aircraft or helicopters, in a 3:1 ratio. Other ammunition types were available, too, and only 200 rounds were typically carried for balance reasons.
The TAM-1’s avionics included a SAGEM ULISS 81 INS, a Thomson-CSF VE-110 HUD, a TMV630 laser rangefinder in a modified nose and a TRT AHV 9 radio altimeter, with all avionics linked through a digital MIL-STD-1553B data bus and a modern “glass cockpit”. A HUD was standard, but an Elbit Systems DASH III HMD could be used by the pilot, too. The DASH GEN III was a wholly embedded design, closely integrated with the aircraft's weapon system, where the complete optical and position sensing coil package was built within the helmet (either the USAF standard HGU-55/P or the Israeli standard HGU-22/P), using a spherical visor to provide a collimated image to the pilot. A quick-disconnect wire powered the display and carried video drive signals to the helmet's Cathode Ray Tube (CRT).
The TAM-1’s development was long and protracted, though, primarily due to lack of resources and the fact that the Georgian air force was in an almost comatose state for several years, so that the potential prime customer for the TAM-1 was not officially available. However, the first TAM-1 prototype eventually made its maiden flight in September 2017. This was just in time, because the Georgian Air Force had formally been re-established in 2016, with plans for a major modernization and procurement program. Under the leadership of Georgian Minister of Defense Irakli Garibashvili the Air Force was re-prioritized and aircraft owned by the Georgian Air Force were being modernized and re-serviced after they were left abandoned for 4 years. This program lasted until 2020. In order to become more independent from foreign sources and support its domestic aircraft industry, the Georgian Air Force eventually ordered eight TAM-1s as Su-25K replacements, which would operate alongside a handful of modernized Su-25KMs from national stock. In the meantime, the new type also attained interest from abroad, e. g. from Bulgaria, the Congo and Cyprus. The IDF thoroughly tested two early production TAM-1s of the Georgian Air Force in 2018, too.

The kit and its assembly:
This rather rigorous conversion had been on my project list for many years, and with the “Gunships” group build at whatifmodellers.com in late 2021 I eventually gathered my mojo to tackle it. The ingredients had already been procured long ago, but there are ideas that make you think twice before you take action…
This build was somewhat inspired by a CG rendition of a modified Su-25 that I came across while doing online search for potential ideas, running under the moniker “Su-125”, apparently created by someone called “Bispro” and published at DeviantArt in 2010; check this: (www.deviantart.com/bispro/art/Sukhoi-Su-125-Foghorn-15043...). The rendition shows a Su-25 with its engines re-located to the rear fuselage in separate nacelles, much like an A-10, plus a T-tail. However, as many photoshopped aircraft, the shown concept had IMHO some flaws. Where would a landing gear go, as the Su-125 still had shoulder wings? The engines’ position and size also looked fishy to me, quite small/narrow and very far high and back – I had doubts concerning the center of gravity. Nevertheless, I liked the idea, and the idea of an “A-10-esque remix” of the classic Frogfoot was born.
This idea was fueled even further when I found out that the Hobbycraft kit lends itself to such a conversion. The kit itself is not a brilliant Su-25 rendition, there are certainly better models of the aircraft in 1:72. However, what spoke for the kit as whiffing fodder was/is the fact that it is quite cheap (righteously so!) and AFAIK the only offering that comes with separate engine nacelles. These are attached to a completely independent central fuselage, and this avoids massive bodywork that would be necessary (if possible at all) with more conventional kits of this aircraft.
Another beneficial design feature is that the wing roots are an integral part of the original engine nacelles, forming their top side up to the fuselage spine. Through this, the original wingspan could be retained even without the nacelles, no wing extension would be necessary to retain the original proportions.
Work started with the central fuselage and the cockpit tub, which received a different (better) armored ejection seat and a pilot figure; the canopy remained unmodified and closed, because representing the model with an open cockpit would have required additional major body work on the spinal area behind the canopy. Inside, a new dashboard (from an Italeri BAe Hawk) was added, too – the original instrument panel is just a flat front bulkhead, there’s no space for the pilot to place the legs underneath the dashboard!
In parallel, the fin underwent major surgery. I initially considered an A-10-ish twin tail, but the Su-25’s high “tail stinger” prevented its implementation: the jet efflux would come very close to the tail surfaces. So, I went for something similar to the “Su-125” layout.
Mounting the OOB stabilizers to the fin was challenging, though. The fin lost its di-electric tip fairing, and it was cut into two sections, so that the tip would become long enough to match the stabilizers. A lucky find in the scrap box was a leftover tail tip from a Matchbox Blackburn Buccaneer, already shortened from a former, stillborn project: it had now the perfect length to take the Su-25 stabilizers! To make it fit on the fin, an 8mm deep section was inserted, in the form of a simple 1.5mm styrene sheet strip. Once dry, the surface was re-built with several PSR layers. Since it would sit further back on the new aircraft’s tail, the stinger with a RHAWS sensor was shortened.
On the fuselage, the attachment points for the wings and the engine nacelles were PSRed away and the front section filled with lots of lead beads, hoping that it would be enough to keep the model’s nose down.
Even though the wings had a proper span for a re-location into a low position, they still needed some attention: at the roots, there’s a ~1cm wide section without sweep (the area which would normally cover the original engine nacelles’ tops). This was mended through triangular 1.5 mm styrene wedges that extended the leading-edge sweep, roughly cut into shape once attached and later PSRed into the wings’ surfaces
The next construction site were the new landing gear attachment points. This had caused some serious headaches – where do you place and stow it? With new, low wings settled, the wings were the only logical place. But the wings were too thin to suitably take the retracted wheels, and, following the idea of a retrofitted existing design, I decided to adopt the A-10’s solution of nacelles into which the landing gear retracts forward, with the wheels still partly showing. This layout option appears quite plausible, since it would be a “graft-on” solution, and it also has the benefit of leaving lots of space for underwing stores, since the hardpoints’ position had to be modified now, too.
I was lucky to have a pair of A-10 landing gear nacelles at hand, left over from a wrecked Matchbox model from childhood time (the parts are probably 35 years old!). They were simply cut out, glued to the Su-25 wings and PSRed into shape. The result looked really good!
At this point I had to decide the model’s overall layout – where to place the wings, the tail and the new engine nacelles. The latter were not 1:72 A-10 transplants. I had some spare engine pods from the aforementioned Matchbox wreck, but these looked too rough and toylike for my taste. They were furthermore too bulky for the Su-25, which is markedly smaller than an A-10, so I had to look elsewhere. As a neat alternative for this project, I had already procured many moons ago a set of 1:144 resin PS-90A engines from a Russian company called “A.M.U.R. Reaver”, originally intended for a Tu-204 airliner or an Il-76 transport aircraft. These turbofan nacelles not only look very much like A-10 nacelles, just a bit smaller and more elegant, they are among the best resin aftermarket parts I have ever encountered: almost no flash, crisp molding, no bubbles, and perfect fit of the parts – WOW!
With these three elements at hand I was able to define the wings’ position, based on the tail, and from that the nacelles’ location, relative to the wings and the fin.
The next challenge: how to attach the new engines to the fuselage? The PS-90A engines came without pylons, so I had to improvise. I eventually found suitable pylons in the form of parts from F-14A underwing missile pylons, left over from an Italeri kit. Some major tailoring was necessary to find a proper position on the nacelles and on the fuselage, and PSRing these parts turned out to be quite difficult because of the tight and labyrinthine space.
When the engines were in place, work shifted towards the model’s underside. The landing gear was fully replaced. I initially wanted to retain the front wheel leg and the main wheels but found that the low wings would not allow a good ground clearance for underwing stores and re-arming the aircraft, a slightly taller solution was necessary. I eventually found a complete landing gear set in the scrap box, even though I am not certain to which aircraft it once belonged? I guess that the front wheel came from a Hasegawa RA-5C Vigilante, while the main gear and the wheels once belonged to an Italeri F-14A, alle struts were slightly shortened. The resulting stance is still a bit stalky, but an A-10 is also quite tall – this is just not so obvious because of the aircraft’s sheer size.
Due to the low wings and the landing gear pods, the Su-25’s hardpoints had to be re-arranged, and this eventually led to a layout very similar to the A-10. I gave the aircraft a pair of pylons inside of the pods, plus three hardpoints under the fuselage, even though all of these would only be used when slim ordnance was carried. I just fitted the outer pair. Outside of the landing gear fairings there would have been enough space for the Frogfoot’s original four outer for pylons, but I found this to be a little too much. So I gave it “just” three, with more space between them.
The respective ordnance is a mix for a CAS mission with dedicated and occasional targets. It consists of:
- Drop tanks under the inner wings (left over from a Bilek Su-17/22 kit)
- A pair of B-8M1 FFAR pods under the fuselage (from a vintage Mastercraft USSR weapon set)
- Two MERs with four 200 kg bombs each, mounted on the pylons outside of the landing gear (the odd MERs came from a Special Hobby IDF SMB-2 Super Mystère kit, the bombs are actually 1:100 USAF 750 lb bombs from a Tamiya F-105 Thunderchief in that scale)
- Four CBU-100 Rockeye Mk. II cluster bombs on the outer stations (from two Italeri USA/NATO weapon sets, each only offers a pair of these)
Yes, it’s a mix of Russian and NATO ordnance – but, like the real Georgian Su-25KM “Scorpion” upgrade, the TAM-1 would certainly be able to carry the same or even a wider mix, thanks to modified bomb racks and wirings. Esp. “dumb” weapons, which do not call for special targeting and guidance avionics, are qualified.
The gun under the nose was replaced with a piece from a hollow steel needle.
Painting and markings:
Nothing unusual here. I considered some more “exotic” options, but eventually settled for a “conservative” Soviet/Russian-style four-tone tactical camouflage, something that “normal” Su-25s would carry, too.
The disruptive pattern was adapted from a Macedonian Frogfoot but underwent some changes due to the T-tail and the engine nacelles. The basic tones were Humbrol 119 (RAF Light Earth), 150 (Forest Green), 195 (Chrome Oxide Green, RAL 6020) and 98 (Chocolate) on the upper surfaces and RLM78 from (Modelmaster #2087) from below, with a relatively low waterline, due to the low-set wings.
As usual, the model received a light black ink washing and some post-shading – especially on the hull and on the fin, where many details had either disappeared under PSR or were simply not there at all.
The landing gear and the lower areas of the cockpit were painted in light grey (Humbrol 64), while the upper cockpit sections were painted with bright turquoise (Modelmaster #2135). The wheel hubs were painted in bright green (Humbrol 101), while some di-electric fairings received a slightly less intense tone (Humbrol 2). A few of these flat fairings on the hull were furthermore created with green decal sheet material (from TL Modellbau) to avoid masking and corrections with paint.
The tactical markings became minimal, matching the look of late Georgian Su-25s. The roundels came from a Balkan Models Frogfoot sheet. The “07” was taken from a Blue Rider decal sheet, it actually belongs to a Lithuanian An-2. Some white stencils from generic MiG-21 and Mi-8 Begemot sheets were added, too, and some small markings were just painted onto the hull with yellow.
Some soot stains around the jet nozzles and the gun were added with graphite, and finally the kit was sealed with a coat of matt acrylic varnish.
A major bodywork project – and it’s weird that this is basically just a conversion of a stock kit and no kitbashing. A true Frogfoot remix! The new engines were the biggest “outsourced” addition, the A-10 landing gear fairings were a lucky find in the scrap box, and the rest is quite generic and could have looked differently. The result is impressive and balanced, though, the fictional TAM-1 looks quite plausible. The landing gear turned out to be a bit tall and stalky, though, making the aircraft look smaller on the ground than it actually is – but I left it that way.

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.

Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Grumman F6F-3 Hellcat:
The Grumman F6F Hellcat was originally conceived as an advanced version of the U.S. Navy's then current front-line fighter, the F4F Wildcat (see NASM collection). The Wildcat's intended replacement, the Vought F4U Corsair (see NASM collection), first flown in 1940, was showing great promise, but development was slowed by problems, including the crash of the prototype.
The National Air and Space Museum's F6F-3 Hellcat, BuNo. 41834, was built at Grumman's Bethpage, New York, factory in February 1944 under contract NOA-(S)846. It was delivered to the Navy on February 7, and arrived in San Diego, California, on the 18th. It was assigned to Fighter Squadron 15 (VF-15) on USS Hornet (CV12) bound for Hawaii. On arrival, it was assigned to VF-3 where it sustained damage in a wheels-up landing at NAS Barbers Point, Hawaii. After repair, it was assigned to VF-83 where it was used in a training role until February 21, 1945. After numerous transfers 41834 was converted to an F6F-3K target drone with the installation of sophisticated radio-control equipment. It was painted red with a pink tail that carried the number 14. Its mission was to be used in Operation Crossroads - the atomic bomb tests at Bikini Atoll. It flew on June 24, 1946, with a pilot, on a practice flight and was launched, unmanned, soon after the first bomb test. Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. Three more manned flights preceded the final unmanned flight on July 25, 1946, which evaluated the first underwater explosion. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible.
F6F-3K 41834 was transferred to NAS Norfolk and logged its last flight on March 25, 1947, with a total of 430.2 flying hours. It was assigned to the National Air Museum on November 3, 1948, and remained at Norfolk until October 4, 1960, when it was moved by barge to Washington and placed in storage. In 1976 this Hellcat was loaned to the USS Yorktown Museum at Charleston, South Carolina. A superficial restoration was performed at the museum, but because of the harsh environment and its poor condition the Hellcat was returned to NASM on March 16, 1982. In 1983, it was sent to Grumman Aerospace where a team of volunteers completely restored the aircraft. In 1985, it was shipped back to the Paul E. Garber Preservation, Restoration and Storage Facility in Suitland, Maryland, and put in storage. NASM's F6F-3 Hellcat is scheduled to be displayed in the new Steven F. Udvar-Hazy center at Dulles International Airport in Virginia in 2004.

Lockheed Martin F-35 "Lightning II" demonstration team members sprint to their positions during the ground show at the Defenders of Liberty Air & Space Show at Barksdale Air Force Base, La., May 17, 2019. The team’s ground show consists of pre-flight inspections with sharp, quick-paced movements that showcase the pride and professionalism of the U.S. Air Force.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the Joint Strike Fighter (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.
A wrecking yard (Australian, New Zealand, and Canadian English), scrapyard (Irish and British English) or junkyard (American English) is the location of a business in dismantling where wrecked or decommissioned vehicles are brought, their usable parts are sold for use in operating vehicles, while the unusable metal parts, known as scrap metal parts, are sold to metal-recycling companies.
Other terms include wreck yard, wrecker's yard, salvage yard, breakers yard, dismantler and scrapheap. In the United Kingdom, car salvage yards are known as car breakers, while motorcycle salvage yards are known as bike breakers. In Australia, they are often referred to as 'Wreckers'.
The most common type of wreck yards are automobile wreck yards, but junkyards for motorcycles, bicycles, small airplanes and boats exist too.
Many salvage yards operate on a local level—when an automobile is severely damaged, has malfunctioned beyond repair, or not worth the repair, the owner may sell it to a junkyard; in some cases—as when the car has become disabled in a place where derelict cars are not allowed to be left—the car owner will pay the wrecker to haul the car away.
Salvage yards also buy most of the wrecked, derelict and abandoned vehicles that are sold at auction from police impound storage lots,and often buy vehicles from insurance tow yards as well.
The salvage yard will usually tow the vehicle from the location of its purchase to the yard, but occasionally vehicles are driven in. At the salvage yard the automobiles are typically arranged in rows, often stacked on top of one another.
Some yards keep inventories in their offices, as to the usable parts in each car, as well as the car's location in the yard. Many yards have computerized inventory systems. About 75% of any given vehicle can be recycled and used for other goods.
In recent years it is becoming increasingly common to use satellite part finder services to contact multiple salvage yards from a single source.
In the 20th century these were call centres that charged a premium rate for calls and compiled a facsimile that was sent to various salvage yards so they could respond directly if the part was in stock. Many of these are now Web-based with requests for parts being e-mailed instantly.
The beautiful Wilayah Mosque has 23 composite domes designed in the traditional form of the Ottoman mosques in Turkey.
Especially interesting is the outer cladding ornamentation technique that was specially developed using computerized "pixel" technique. This new technique allows patterning of ornaments using mosaic tiles that can be displayed in any form or colour in a high degree of smoothness and quality.
The outer cladding of the 30m main dome is finished in turquoise mosaic tiles with floral motifs in the style of Safavid mosques in Isfahan. Its inner cladding is of a simple relief ornamentation in pale cream.
The Wilayah Mosque contract secured by SL-Rasch GmbH.
Bangladesh Railway (BR) started its journey in this portion of the sub-continent 142 years ago. Historically Bangladesh owned the Railway network, which was a part of the sub-continent. BR has recently introduced train related information using IVR (Interactive Voice Response) system through Mobile Phone and has taken initiative for computerization of pay roll, asset management, accounting, inventory control etc. which are the steps towards the implementation of Digital Bangladesh.
In Bangladesh, due to the huge population in the country, an inadequate number of seats on the local trains, and punishing poverty, some people are forced to borrow a ride now and then. Some are so poor that they cant buy ticket even. They ride on the roof top as well as between the carriages of Train or seat in floor between two carriages, canteen, beside door area every where.

Two Lockheed Martin F-35A Lighting II "Joint Strike Fighter's" assigned to the 62nd Fighter Squadron, Luke Air Force Base Ariz, fly near an Arizona National Guard Boeing KC-135 Stratotanker Aug. 4, 2017. Four F-35’s participated in a missing man formation fly-over during WWII pilot 2nd Lt. Charles E. Carlson’s funeral in Pennsylvania more than 70 years after being shot down over Germany in World War II when he was assigned to the 62 FS.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the "Joint Strike Fighter" (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms.
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes.
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system.
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft.
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency.
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.
Two Lockheed Martin F-35B "Lightning II's" with Marine Fighter Attack Squadron (VMFA) 211 “Wake Island Avengers,” 3rd Marine Aircraft Wing, taxi the runway after landing at Nellis Air Force Base, Nev., July 5. A total of 10 aircraft and more than 250 Marines with VMFA-211 will participate in Red Flag 17-3, a realistic combat training exercise hosted by the U.S. Air Force to assess the squadron’s ability to deploy and support contingency operations using the F-35B. Red Flag 17-3 begins July 10 and ends July 28.

A more compact modern assault weapon used by the UT Enforcers, starting from the year 2011. It employs the 5x56 round.
It is a weapon in the L series.
It has a unique sighting system. The weapon feeds info into the users HUD display, including ammunition remaining, heat, condition of rifle, and such. The front sensor module built into the front of the handguard holds a minimal magnification camera, rangefinders, and compass sensors. This module is directly connected to the Enforcer suit and sighting unit. It feeds the info into the scope and user's HUD, and sends camera feed to the scope.
The sensor module also sends information to the suit, which also has cameras. More advanced cameras, such as high magnification, infrared vision, etc. Depending on the direction the gun is pointed at, the cameras follow the direction the weapon is facing, and sends camera feed into the sighting unit.
This weapon was built to last, and can endure much punishment. In a complete worst case scenario, in which all electronic systems are destroyed, the iron sights can be used.
Compared to previous L series weapons, this gun features a carry handle with integrated computer sight, and does not have a accessory rail for scope. It's computerized hologram sight is built into the physical sight of the carry handle. It is smaller and much more compact.

1962 Oldsmbile F-85 Jetfire Hardtop Coupe
General Motors was flexing its engineering muscles in the early Sixties, especially when it came to the corporation’s new Y-body small cars. The line of 112-inch-wheelbase premium compacts included the Pontiac Tempest with independent rear suspension and curved “rope drive” driveshaft. Meanwhile, the Buick Special and Oldsmobile F-85 bowed in 1961 with an aluminum V8, followed in ’62 by a 90-degree V6 initially exclusive to Buick.
In April 1962, Olds introduced America’s first mass-market turbocharged car, the F-85 Jetfire. (Chevrolet brought out its turbocharged Corvair Monza Spyder about a month later.) A turbocharger uses the force of escaping exhaust gas to turn impellers that raise air pressure in the intake manifold, forcing the fuel mixture into the combustion chambers for more power. Working with Garrett AirResearch, Olds adapted a turbocharger to the 215-cid aluminum V-8. Where naturally aspirated versions made 155 or 185 horsepower, the Jetfire’s “Turbo Rocket” version put out 215 horsepower.
Turbo engines usually have reduced compression to avoid preignition or “pinging,” but to reach the magic one-horsepower-per-cubic-inch mark, Olds engineers used a high 10.25:1 compression. To head off detonation, an ingenious fluid-injection system added a 50/50 mix of water and alcohol (“Turbo-Rocket Fluid”) to the fuel mixture to lower the combustion-chamber temperature. A wastegate limited turbo boost.
Inside, a vacuum-boost gauge on the standard center console indicated if the turbo was doing its job. The gauge also included a warning light to remind owners to refill the Turbo-Rocket Fluid tank—a bottle in the engine bay held an emergency supply.
A Jetfire could go 0-60 mph in 8.5 seconds and had a top speed of 107. The quarter-mile run was achieved in 16.8 seconds. All Jetfires were hardtop coupes with standard front bucket seats. The Jetfire cost $3049.
Oldsmobile engineers came up with a lot of ingenious engineering to make the turbo work, but ultimately the engine was unreliable in the hands of average owners who often failed to refill the Turbo-Rocket Fluid tank. In 1965 Olds recalled the Jetfires to replace the turbocharger with a conventional four-barrel carburetor. Today, turbos benefit from computerized technology and are increasingly popular because they generate more power from small, fuel-efficient engines.
Only 3765 Jetfires were sold in 1962, with a further 5842 built in its final year of 1963. It’s estimated that only 30-35 with a functioning turbocharger remain. It is one of only about 50 ’62s with a four-speed manual transmission.
LEMOORE, California (June 5, 2019) Capt. Tommy Beau Locke, assigned to the Rough Raiders of Strike Fighter Squadron (VFA) 125, flies the first Lockheed Martin F-35C Lightning II aircraft attached to the "Black Knights" of Marine Fighter Attack Squadron (VMFA) 314 over Naval Air Station Lemoore in formation with an F/A-18A++ assigned to VMFA-314 flown by Lt.

The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.
‘The Boss’ had been sewing us some new face masks to give us a larger supply for our various trips out into the wilds of Grimsby and environs. Now you would expect her choice of sewing machine would be something recent, computerized, even, perhaps solar powered or whatever is currently the latest and greatest. But no. She uses a nearly century old Singer foot-treadle model, as she has since well before we were married. She loves that thing and refuses to part with it. And she is not alone. Another family member has already called dibs on it should she ever decide to part with it (as if!) or when the inevitable happens. They argue that it provides much better control for them. And it looks cool. Anyway, it stands next to a window that allows the rising sun in as in this image. Those low sunbeams initially ticked me off a tad as they were causing flare that seem inescapable until I found a significantly shooting position. I shot it both ways and in reviewing the images I felt the clean versions were a bit too clinical for my liking and I opted to use the ones with flare. Go figure. Oh, and Red Rule applies, of course. - JW

Some background:
The Waffenträger (Weapon Carrier) VTS3 “Diana” was a prototype for a wheeled tank destroyer. It was developed by Thyssen-Henschel (later Rheinmetall) in Kassel, Germany, in the late Seventies, in response to a German Army requirement for a highly mobile tank destroyer with the firepower of the Leopard 1 main battle tank then in service and about to be replaced with the more capable Leopard 2 MBT, but less complex and costly. The main mission of the Diana was light to medium territorial defense, protection of infantry units and other, lighter, elements of the cavalry as well as tactical reconnaissance. Instead of heavy armor it would rather use its good power-to-weight ratio, excellent range and cross-country ability (despite the wheeled design) for defense and a computerized fire control system to accomplish this mission.
In order to save development cost and time, the vehicle was heavily based on the Spähpanzer Luchs (Lynx), a new German 8x8 amphibious reconnaissance armored fighting vehicle that had just entered Bundeswehr service in 1975. The all-wheel drive Luchs made was well armored against light weapons, had a full NBC protection system and was characterized by its extremely low-noise running. The eight large low-pressure tires had run-flat properties, and, at speeds up to about 50 km/h, all four axles could be steered, giving the relatively large vehicle a surprising agility and very good off-road performance. As a special feature, the vehicle was equipped with a rear-facing driver with his own driving position (normally the radio operator), so that the vehicle could be driven at full speed into both directions – a heritage from German WWII designs, and a tactical advantage when the vehicle had to quickly retreat from tactical position after having been detected. The original Luchs weighed less than 20 tons, was fully amphibious and could surmount water obstacles quickly and independently using propellers at the rear and the fold back trim vane at the front. Its armament was relatively light, though, a 20 mm Rheinmetall MK 20 Rh 202 gun in the turret that was effective against both ground and air targets.
The Waffenträger “Diana” used the Luchs’ hull and dynamic components as basis, and Thyssen-Henschel solved the challenge to mount a large and heavy 105 mm L7 gun with its mount on the light chassis through a minimalistic, unmanned mount and an autoloader. Avoiding a traditional manned and heavy, armored turret, a lot of weight and internal volume that had to be protected could be saved, and crew safety was indirectly improved, too. This concept had concurrently been tested in the form of the VTS1 (“Versuchsträger Scheitellafette #1) experimental tank in 1976 for the Kampfpanzer 3 development, which eventually led to the Leopard 2 MBT (which retained a traditional turret, though).
For the “Diana” test vehicle, Thyssen-Henschel developed a new low-profile turret with a very small frontal area. Two crew members, the commander (on the right side) and the gunner (to the left), were seated in/under the gun mount, completely inside of the vehicle’s hull. The turret was a very innovative construction for its time, fully stabilized and mounted the proven 105mm L7 rifled cannon with a smoke discharger. Its autoloader contained 8 rounds in a carousel magazine. 16 more rounds could be carried in the hull, but they had to be manually re-loaded into the magazine, which was only externally accessible. A light, co-axial 7,62mm machine gun against soft targets was available, too, as well as eight defensive smoke grenade mortars.
The automated L7 had a rate of fire of ten rounds per minute and could fire four types of ammunition: a kinetic energy penetrator to destroy armored vehicles; a high explosive anti-tank round to destroy thin-skinned vehicles and provide anti-personnel fragmentation; a high explosive plastic round to destroy bunkers, machine gun and sniper positions, and create openings in walls for infantry to access; and a canister shot for use against dismounted infantry in the open or for smoke charges. The rounds to be fired could be pre-selected, so that the gun was able to automatically fire a certain ammunition sequence, but manual round selection was possible at any time, too.
In order to take the new turret, the Luchs hull had to be modified. Early calculations had revealed that a simple replacement of the Luchs’ turret with the new L7 mount would have unfavorably shifted the vehicle’s center of gravity up- and forward, making it very nose-heavy and hard to handle in rough terrain or at high speed, and the long barrel would have markedly overhung the front end, impairing handling further. It was also clear that the additional weight and the rise of the CoG made amphibious operations impossible - a fate that met the upgraded Luchs recce tanks in the Eighties, too, after several accidents with overturned vehicles during wading and drowned crews. With this insight the decision was made to omit the vehicle’s amphibious capability, save weight and complexity, and to modify the vehicle’s layout considerably to optimize the weight distribution.
Taking advantage of the fact that the Luchs already had two complete driver stations at both ends, a pair of late-production hulls were set aside in 1977 and their internal layout reversed. The engine bay was now in the vehicle’s front, the secured ammunition storage was placed next to it, behind the separate driver compartment, and the combat section with the turret mechanism was located behind it. Since the VTS3s were only prototypes, only minimal adaptations were made. This meant that the driver was now located on the right side of the vehicle, while and the now-rear-facing secondary driver/radio operator station ended up on the left side – much like a RHD vehicle – but this was easily accepted in the light of cost and time savings. As a result, the gun and its long, heavy barrel were now located above the vehicle’s hull, so that the overall weight distribution was almost neutral and overall dimensions remained compact.
Both test vehicles were completed in early 1978 and field trials immediately started. While the overall mobility was on par with the Luchs and the Diana’s high speed and low noise profile was highly appreciated, the armament was and remained a source of constant concern. Shooting in motion from the Diana turned out to be very problematic, and even firing from a standstill was troublesome. The gun mount and the vehicle’s complex suspension were able to "hold" the recoil of the full-fledged 105-mm tank gun, which had always been famous for its rather large muzzle energy. But when fired, even in the longitudinal plane, the vehicle body fell heavily towards the stern, so that the target was frequently lost and aiming had to be resumed – effectively negating the benefit from the autoloader’s high rate of fire and exposing the vehicle to potential target retaliation. Firing to the side was even worse. Several attempts were made to mend this flaw, but neither the addition of a muzzle brake, stronger shock absorbers and even hydro-pneumatic suspension elements did not solve the problem. In addition, the high muzzle flames and the resulting significant shockwave required the infantry to stay away from the vehicle intended to support them. The Bundeswehr also criticized the too small ammunition load, as well as the fact that the autoloader magazine could not be re-filled under armor protection, so that the vehicle had to retreat to safe areas to re-arm and/or to adapt to a new mission profile. This inherent flaw not only put the crew under the hazards of enemy fire, it also negated the vehicle’s NBC protection – a serious issue and likely Cold War scenario. Another weak point was the Diana’s weight: even though the net gain of weight compared with the Luchs was less than 3 tons after the conversion, this became another serious problem that led to the Diana’s demise: during trials the Bundeswehr considered the possibility to airlift the Diana, but its weight (even that of the Luchs, BTW) was too much for the Luftwaffe’s biggest own transport aircraft, the C-160 Transall. Even aircraft from other NATO members, e.g. the common C-130 Hercules, could hardly carry the vehicle. In theory, equipment had to be removed, including the cannon and parts of its mount.
Since the tactical value of the vehicle was doubtful and other light anti-tank weapons in the form of the HOT anti-tank missile had reached operational status, so that very light vehicles and even small infantry groups could now effectively fight against full-fledged enemy battle tanks from a safe distance, the Diana’s development was stopped in 1988. Both VTS3 prototypes were mothballed, stored at the Bundeswehr Munster Training Area camp and are still waiting to be revamped as historic exhibits alongside other prototypes like the Kampfpanzer 70 in the German Tank Museum located there, too.

The kit and its assembly:
I have been a big Luchs fan since I witnessed one in action during a public Bundeswehr demo day when I was around 10 years old: a huge, boxy and futuristic vehicle with strange proportions, gigantic wheels, water propellers, a mind-boggling mobility and all of this utterly silent. Today you’d assume that this vehicle had an electric engine – spooky! So I always had a soft spot for it, and now it was time and a neat occasion to build a what-if model around it.
This fictional wheeled tank prototype model was spawned by a leftover Revell 1:72 Luchs kit, which I had bought some time ago primarily for the turret, used in a fictional post-WWII SdKfz. 234 “Puma” conversion. With just the chassis left I wondered what other use or equipment it might take, and, after several weeks with the idea in the back of my mind, I stumbled at Silesian Models over an M1128 resin conversion set for the Trumpeter M1126 “Stryker” 8x8 APC model. From this set as potential donor for a conversion the prototype idea with an unmanned turret was born.
Originally I just planned to mount the new turret onto the OOB hull, but when playing with the parts I found the look with an overhanging gun barrel and the bigger turret placed well forward on the hull goofy and unbalanced. I was about to shelf the idea again, until I recognized that the Luchs’ hull is almost symmetrical – the upper hull half could be easily reversed on the chassis tub (at least on the kit…), and this would allow much better proportions. From this conceptual change the build went straightforward, reversing the upper hull only took some minor PSR. The resin turret was taken mostly OOB, it only needed a scratched adapter to fit into the respective hull opening. I just added a co-axial machine gun fairing, antenna bases (from the Luchs kit, since they could, due to the long gun barrel, not be attached to the hull anymore) and smoke grenade mortars (also taken from the Luchs).
An unnerving challenge became the Luchs kit’s suspension and drive train – it took two days to assemble the vehicle’s underside alone! While this area is very accurate and delicate, the fact that almost EVERY lever and stabilizer is a separate piece on four(!) axles made the assembly a very slow process. Just for reference: the kit comes with three and a half sprues. A full one for the wheels (each consists of three parts, and more than another one for suspension and drivetrain!
Furthermore, the many hull surface details like tools or handles – these are more than a dozen bits and pieces – are separate, very fragile and small (tiny!), too. Cutting all these wee parts out and cleaning them was a tedious affair, too, plus painting them separately.
Otherwise the model went together well, but it’s certainly not good for quick builders and those with big fingers and/or poor sight.
Painting and markings:
The paint scheme was a conservative choice; it is a faithful adaptation of the Bundeswehr’s NATO standard camouflage for the European theatre of operations that was introduced in the Eighties. It was adopted by many armies to confuse potential aggressors from the East, so that observers could not easily identify a vehicle and its nationality. It consists of a green base with red-brown and black blotches, in Germany it was executed with RAL tones, namely 6031 (Bronze Green), 8027 (Leather Brown) and 9021 (Tar Black). The pattern was standardized for each vehicle type and I stuck to the official Luchs pattern, trying to adapt it to the new/bigger turret. I used Revell acrylic paints, since the authentic RAL tones are readily available in this product range (namely the tones 06, 65 and 84). The big tires were painted with Revell 09 (Anthracite).
Next the model was treated with a highly thinned washing with black and red-brown acrylic paint, before decals were applied, taken from the OOB sheet and without unit markings, since the Diana would represent a test vehicle. After sealing them with a thin coat of clear varnish the model was furthermore treated with lightly dry-brushed Revell 45 and 75 to emphasize edges and surface details, and the separately painted hull equipment was mounted. The following step was a cloudy treatment with watercolors (from a typical school paintbox, it’s great stuff for weathering!), simulating dust residue all over the hull. After a final protective coat with matt acrylic varnish I finally added some mineral artist pigments to the lower hull areas and created mud crusts on the wheels through light wet varnish traces into which pigments were “dusted”.
Basically a simple project, but the complex Luchs kit with its zillion of wee bits and pieces took time and cost some nerves. However, the result looks pretty good, and the Stryker turret blends well into the overall package. Not certain how realistic the swap of the Luchs’ internal layout would have been, but I think that the turret moved to the rear makes more sense than the original forward position? After all, the model is supposed to be a prototype, so there’s certainly room for creative freedom. And in classic Bundeswehr colors, the whole thing even looks pretty convincing.

Some Background:
On 23 January 1992, the Lithuanian Minister of Defense signed an order establishing the staff for the Aviation Base of the Aviation Service. But an actual base in the Šiauliai airport territory (Barysiai airfield) was not established until March, when according to the ordinance of the Government of Lithuanian Republic, all the infrastructure, buildings, territory and 24 An-2 aircraft were passed from ”Lithuanian Airlines" to the Aviation Service of the Ministry of Defense in January 1992.
On 12 June 1992, the first time after regaining the independence of Lithuania, An-2 aircraft, marked with the double cross of Vytis on its wings – the distinguishing sign of Lithuanian Air Force – took off from Barysiai airfield. This date is considered to be the Aviation Base foundation date. In February 1993 four L-39C Albatros aircraft were brought from Kyrgyzstan.
After 1 March 1993 Aviation Service was reformed to the Lithuanian Air Force and Aviation Base was renamed the First Aviation Base of the Lithuanian Air Force. In January 1994 Lithuania officially applied for NATO membership, and the country also looked out for a relatively cheap multi-purpose fighter that would fulfill both air space defence and attack tasks, the latter primarily against potential targets at sea (e. g. fast hoovercraft landing ships operated by the Russian Baltic Fleet).
After evaluating several options, the Lithuanian Air Force settled for a surprising aircraft: the venerable MiG-21! After the demise of the Soviet Union, several international companies started to offer conversion and upgrade programs for the widely used tactical fighter, about 5.000 specimen had been built to date. One of the first companies to enter the market was Israel Aircraft Industries: IAI's Lahav Division of (IAI) had developed the so-called MiG-21 2000 upgraded fighter and ground attack version, based on the MiG-21bis and the export MiG-21MF fighter aircraft.
The MiG-21 2000 upgrade provided modifications to the cockpit configuration, avionics architecture and weapons systems, enabling the MiG-21 2000 to compete with Western developed fighters like the F-16 and to make the transition to Western standards. The aircraft's original systems and components were retained wherever mission effectiveness was not compromised.
IAI Lahav augmented the original weapons system by introducing an EL/M-2032 radar, developed by IAI Elta Electronic Industries, based in Ashdod. The radar, which uses a low sidelobe planar array antenna and pulse Doppler beam sharpening, provides all-altitude, all-aspect look-up / look-down and shoot-down capability, as well as beyond-visual-range capability. In order to make the radar compatible with Western ordnance, a new armament interface and control unit were added, too, which enabled computerized control and release of weapons, including third and fourth-generation air-to-air missiles and precision-guided munitions of Western and Eastern provenance.
This system also gave the pilot the ability to use blind attack as well as continuously computed impact point (CCIP) and dive-toss bombing techniques. CCIP bombing involves the deployment of air-to-ground weapons, using the HUD to indicate the impact point for release of the weapons. Dive-toss bombing involves the release of air-to-ground weapons at the end of a steep dive manoeuver towards the target.
The MiG-21 2000 cockpit featured a new pilot-friendly layout that overcame the shortcomings of the original cockpit layout, which was crowded and lacked most of the desired man-machine interface characteristics. It incorporated a head-up display (HUD), eye-level multifunction color displays, hands on throttle and stick control (HOTAS), solid-state charge coupled device (CCD) camera, videotape recorder, and a one-piece windshield.
The MiG-21 2000 could be equipped with a display and sight helmet (DASH) system, supplied by Elbit of Haifa, which enabled the pilot to aim the weapons simply by looking at the target. The system worked by measuring the pilot's line of sight relative to the aircraft, and transferred the information to the aircraft's sensors, avionics and weapon systems. The helmet displayed vital information, such as the missile line of sight, missile status, flight information and warning data, on the visor. The DASH helmet allowed the pilot to fly head-up and off-boresight and assisted the pilot to detect, identify and shoot earlier.
IAI Lahav's upgrade package could be tailored to meet the customer's specific operational and budgetary requirements - the Lithuanian package included the radar, cockpit and also the DASH update and was rumored to cost around 4 Mio. USD per aircraft, and Lithuania was, together with Romania (where 110 MiG-21 were to be updated), lead customer.
As conversion basis, Lithuania purchased fifteen MiG-21 airframes for an unknown sum from the Ukraine, which had inherited a considerable MiG-21 fleet after the demise of the Soviet Union but did not (want to) operate it. The deal included thirteen airworthy MiG-21bis fighters and two MiG-21U trainers with few flying hours on the clocks, and - stripped off any military equipment - the small fleet was gradually transferred as disassembled kits via air ferry in Antonov Airlines An-124 transporters to Aerostar in Romania for conversion, starting in early 1996.
The first batch of Lithuanian MiG-21 2000, three fighters and one trainer, arrived in mid-1997 from Bacau on their own power and with civil Ukrainian registrations, and the Lithuanian Air Force’s fighter squadron, the Naikintuvu Eskadra, became ready for service in February 1998.
The rest of the country’s small MiG-21 fleet was delivered in the course of the same year, and these aircraft were semi-officially christened "Globėjas" (Guardian). Since the late Nineties, the Globėjas fighters provide the backbone of Lithuania's air defenses, with aircraft holding Quick Reaction Alert. QRA missions – so-called Alpha Scrambles – have constantly been on the rise thanks to the Russia’s increased aggression towards NATO. The MiG’s have regularly launched to intercept and shadow Russian Air Force Il-20 intelligence gathering aircraft over the Baltic Sea, as well as Tu-16 and Tu-95 patrols and even some Sukhoi Su-27s.
Lithuanian pilots use “hit and run” style tactics to deal with air threats, due to the limited range and endurance of their mounts - but this is of little concern due to the country's relatively small size and the defensive nature of the machines' tasks. While the Globėjas lack a beyond-visual range missile, although they could carry one, they have the ability to carry a range of different short-range air-to-air missiles like the Israeli Python III, which Lithuania procured from Rafael in Haifa as primary air-to-air missile.
After Lithuania joined NATO organization in 2004, its (alongside Latvia's and Estonia's) air space has been protected by NATO. NATO members provide usually 4 fighter aircraft, based in Lithuania, to police the Baltic States’ airspace, where they support the Lithuanian MiG-21 fleet. The duties rotate between NATO members (which started in March 2004 with Belgium Air Force F-16s) and most NATO members that operate fighters have made temporary deployments to Lithuania.
The Lithuanian Globėjas were also in regular demand as a simulated threat, and have gone up against US F-16s, F-15s, F/A-18s and A-10s, as well as the many different European fighter types that frequently rotate into the small country, including the Eurofighter, German F-4F Phantom IIs or French Mirage 2000.
Anyway, the Globėjas' airframes sooner or later reached their flying hour limits, and will be phased out towards 2020. As a replacement Lithuania will begin taking delivery of its first batch of ex-Portuguese F-16s in 2016, while the Baltic States are considering in the near future to protect their airspace on their own.

The kit and its assembly:
This kit is the entry for the 2016 "One Week Group Build" at whatifmodelers.com, which ran from 29th of April until 8th May (so, actually nine days...). I had this project earmarked for the recent "Cold War" GB, but it fell outside of the build's time horizon. But despite the dubious kit as basis, I tackled the build since I had anything else already at hand.
The basis is the MiG-21-93 demonstrator kit from Ukrainian manufacturer Condor, one of the many reincarnations of the venerable KP MiG-21bis, but with some updates. You get, for instance, engraved, very fine panel lines, some typical details were added like the wraparound windscreen (wrong shape, though) and the radar warning fairing on the fin as well as an extra sprue with modern Russian ordnance – apparently from some other kit!
On the downside, there's overall mediocre fit due to the molds' age, some dubious details (anything appears softened or blurred…) or the simple lack thereof (e. g. there’s no ventral gun fairing at all). But there’s nothing that could not be mended, and after all this is just a whiffy version.
Since there was only one week time to build the thing and make beauty pics, the whole project remained close to OOB status, even though a lot of detail changes or additions were made in order to convert the Russian MiG-21-93 into an earlier but similar Israeli MiG-21 2000 derivative.
These mods include:
- A Martin Baker ejection seat, with wire trigger handles
- HUD made from clear styrene
- Lowered flaps
- An added jet pipe/interior for the otherwise bleak exhaust (parts from a Kangnam Yak-38)
- Hydraulic pipes on the landing gear, made from very thin wire
- Some more/different blade antennae
- Measuring vanes on the pitot boom
- Different GSh-23 gun fairing, from an Academy MiG-23
- Thinner blast deflector plates under the anti-surge doors
- A pair of Python III AAMs, plus respective launch rails
- Different centerline drop tank, from an F-5E
- Scratched chaff/flare dispensers under the rear fuselage (as carried by the MiG-21 2000 demonstrator)
Building the model went straightforward, but it took some putty work to fill some seams, dents and holes all around the kit. Biggest issue was a hole in front of the cockpit screen, where simply not enough styrene had been injected into the mould!
Painting and markings:
The Lithuanian Air Force as operator for this build was chosen because it would not only fit into the real world timeline (even though I doubt that there would have been any budget for this aircraft at that time, even if MiG-21s had not been upgraded at all...) and because the potential livery would be very simple: contemporary L-39 trainers, C-27L Spartan as well as some L-410 and Mi-8 transporters carry a uniform, dull grey livery. Why not apply it on an air superiority fighter, too?
Finding an appropriate tone was not easy, though. Some sources claim the grey tone to be FS 36306, others refer to FS 36270 or "close to Blue/Grey FS35237", but IMHO none of the cited Federal Standard tones works well. Real world Lithuanian aircraft appear pretty dark and dull, and the color also features a greenish, slate grey hue - it's a unique color indeed.
After some trials (and also wishing to avoid mixing) I settled for Humbrol 111 (German Field Grey, a.k.a. Uniform Grey) as basic tone. It's a rather dark choice, but I wanted some good contrast to the national markings. A full wraparound livery appeared a little too dark and boring, so I added light blue wing undersurfaces (Humbrol 115). The kit received a light black in wash and some panel shading, primarily in order to add some life to the otherwise uniform surface.
Details were painted according to real world MiG-21 pics: the cockpit became classic teal with light grey instrument panels, plus OOB decals for the dashboard and side consoles. The landing gear struts were painted in a light, metallic grey (Humbrol 127 + 56) while the wells were painted in an odd primer color, a mix of Aluminum, Sand and Olive Drab. Parts of the covers were painted with Humbrol 144 (Blue Grey), seen on a modernized real world MiG-21. The wheel discs became bright green.
IAI's MiG-21 2000 demonstrator from 1993 had a black radome (as well as later Romanian LanceR Cs), so I adapted this detail for my build. Other typical di-electric fairings on a MiG-21's hull were painted in slightly darker camouflage colors, while the fin's leading edge became dark grey.
The blast deflector plates received yellow and black warning stripes, and some potentially dangerous parts for the ground crews like the pointed anti-flutter booms were painted red. The Python IIIs were simply painted all-white, mounted on grey launch rails - a harsh contrast to the dull rest of the aircraft.
Main markings come from a Blue Rider Publishing aftermarket sheet for modern Lithuanian aircraft. This set also includes the small Air Force crests, which I put on the nose, as well as the typical, blue tactical codes.
The stencils come from the scrap box, the small Lithuanian flag stripes on the tail rudder were created from single decal stripes, a personal addition inspired by Lithuanian C-27J transporters. They add some more color to the otherwise murky Baltic MiG fighter.
The silver ring around the air intake as well as the stripes at the flaps and the rudder were created with simple decal stripes instead of paint.
Finally, after I added some graphite soot around the jet exhaust and some panle lines with a pencil (e .g. the blow-in doors and airbrake outlines), the kit was sealed with hardly thinned Revell matt acrylic varnish, trying to create a really dull finish.
A tough build, despite being mostly OOB, but the details took their toll. This Baltic MiG does not look flashy, but, with IAI's real world MiG-21 2000 as well as the LanceR conversion for Romania in the Nineties, this one is pretty plausible. And with the simple paint scheme, the MiG-21 looks even pretty chic!

The Mark III Escort was developed under the cod name Erika, and launched in 1980, unlike the Mark II the new car was more than a reskin of the previous generation Escort. The Mark III was a departure from the two previous models, the biggest changes being the adoption of front-wheel drive, and the new hatchback body. The car used Ford's contemporary design language of the period with the black louvred radiator grille and straked rear lamp clusters, as well as introducing the aerodynamic "bustle-back" bootlid stump. Sales in the United Kingdom increased, and by 1982 it had overtaken the ageing Cortina as the nation's best-selling car, beginning an eight-year run as Britain's best selling car.
New were the overhead camshaft CVH engines in 1.3 L and 1.6 L formats, with the older Ford Kent-based "Valencia" engine from the Fiesta powering the 1.1 L. From launch, the car was available in base (Popular), L, GL, Ghia and XR3 trim.
A convertible version, made by coachbuilder Karmann, appeared the same year as the five-door estate (1983). It was the first drop-top car produced by Ford Europe since the Corsair of the 1960s. The Escort Cabriolet was initially available in both XR3i and Ghia specification, but the Ghia variant was later dropped.
To compete with Volkswagen's Golf GTI, a hot hatch version of the Mark III was developed – the XR3. Initially this featured a tuned version of the 1.6 L CVH engine of 96bhp
fitted with a twin-choke Weber carburettor, uprated suspension and numerous cosmetic alterations.
The car lacked the five speed transmission and fuel injection of its Volkswagen rival a situation addressed in October 1982 for the 1983 model year with the arrival of the XR3i with 105bhp eight months behind the limited edition (8,659 examples), racetrack-influenced RS 1600i. The Cologne-developed RS received a more powerful engine with 115 PS (85 kW), thanks to computerized ignition and a modified head as well as the fuel injection

Some Background:
The Lockheed F-94 Starfire was a first-generation jet aircraft of the United States Air Force. It was developed from the twin-seat Lockheed T-33 Shooting Star in the late 1940s as an all-weather, day/night interceptor, replacing the propeller-driven North American F-82 Twin Mustang in this role. The system was designed to overtake the F-80 in terms of performance, but more so to intercept the new high-level Soviet bombers capable of nuclear attacks on America and her Allies - in particular, the new Tupelov Tu-4. The F-94 was furthermore the first operational USAF fighter equipped with an afterburner and was the first jet-powered all-weather fighter to enter combat during the Korean War in January 1953.
The initial production model, the F-94A, entered operational service in May 1950. Its armament consisted of four 0.50 in (12.7 mm) M3 Browning machine guns mounted in the fuselage with the muzzles exiting under the radome for the APG-33 radar, a derivative from the AN/APG-3, which directed the Convair B-36's tail guns and had a range of up to 20 miles (32 km). Two 165 US Gallon (1,204 litre) drop tanks, as carried by the F-80 and T-33, were carried on the wingtips. Alternatively, these could be replaced by a pair of 1,000 lb (454 kg) bombs under the wings, giving the aircraft a secondary fighter bomber capability. 109 were produced.
The subsequent F-94B, which entered service in January 1951, was outwardly virtually identical to the F-94A. Its Allison J33 turbojet had a number of modifications made, though, which made it a very reliable engine. The pilot was provided with a roomier cockpit and the canopy received a bow frame in the center between the two crew members. A new Instrument Landing System (ILS) was fitted, too, which made operations at night and/or in bad weather much safer. However, this new variant’s punch with just four machine guns remained weak, and, to improve the load of fire, wing-mounted pods with two additional pairs of 0.5” machine guns were introduced – but these hardly improved the interceptor’s effectiveness. 356 of the F-94B were nevertheless built.
The following F-94C was extensively modified and initially designated F-97, but it was ultimately decided just to treat it as a new version of the F-94. USAF interest was lukewarm since aircraft technology had already developed at a fast pace – supersonic performance had already become standard. Lockheed funded development themselves, converting two F-94B airframes to YF-94C prototypes for evaluation with a completely new, much thinner wing, a swept tail surface and a more powerful Pratt & Whitney J48. This was a license-built version of the afterburning Rolls-Royce Tay, which produced a dry thrust of 6,350 pounds-force (28.2 kN) and approximately 8,750 pounds-force (38.9 kN) with afterburning. Instead of machine guns, the proposed new variant was exclusively armed with unguided air-to-air missiles.
Tests were positive and eventually the F-94C was adopted for USAF service, since it was the best interim solution for an all-weather fighter at that time. It still had to rely on Ground Control Interception Radar (GCI) sites to vector the interceptor to intruding aircraft, though.
The F-94C's introduction and the availability of the more effective Northrop F-89C/D Scorpion and the North American F-86D Sabre interceptors led to a quick relegation of the earlier F-94 variants from mid-1954 onwards to second line units and to Air National Guards. By 1955 most of them had already been phased out of USAF service, and some of these relatively young surplus machines were subsequently exported or handed over to friendly nations, too. When sent to the ANG, the F-94As were modified by Lockheed to F-94B standards and then returned to the ANG as B models. They primarily replaced outdated F-80C Shooting Stars and F-51D/H Mustangs.
At that time the USAF was looking for a tactical reconnaissance aircraft, a more effective successor for the RF-80A which had shown its worth and weaknesses during the Korea War. For instance, the plane could not fly at low altitude long enough to perform suitable visual reconnaissance, and its camera equipment was still based on WWII standards. Lockheed saw the opportunity to fill this operational gap with conversions of existing F-94A/B airframes, which had, in most cases, only had clocked few flying hours, primarily at high altitudes where Soviet bombers were expected to lurk, and still a lot of airframe life to offer. This led to another private venture, the RF-94B, auspiciously christened “Stargazer”.
The RF-94B was based on the F-94B interceptor with its J33 engine and the original unswept tail. The F-94B’s wings were retained but received a different leading-edge profile to better cope with operations at low altitude. The interceptor’s nose with the radome and the machine guns underneath was replaced by a new all-metal nose cone, which was more than 3 feet longer than the former radar nose, with windows for several sets of cameras; the wedge-shaped nose cone quickly earned the aircraft the unofficial nickname “Crocodile”.
One camera was looking ahead into flight direction and could be mounted at different angled downward (but not moved during flight), followed by two oblique cameras, looking to the left and the right, and a vertical camera as well as a long-range camera focussed on the horizon, which was behind a round window at port side. An additional, spacious compartment in front of the landing gear well held an innovative Tri-Metrogen horizon-to-horizon view system that consisted of three synchronized cameras. Coupled with a computerized control system based on light, speed, and altitude, it adjusted camera settings to produce pictures with greater delineation.
All cameras could be triggered individually by pilot or a dedicated observer/camera systems operator in the 2nd seat. Talking into a wire recorder, the crew could describe ground movements that might not have appeared in still pictures. A vertical view finder with a periscopic presentation on the cockpit panel was added for the pilot to enhance visual reconnaissance and target identification directly under the aircraft. Using magnesium flares carried under its wings in flash-ejector cartridges, the RF-94B was furthermore able to fly night missions.
The RF-94B was supposed to operate unarmed, but it could still carry a pair of 1.000 lb bombs under its wings or, thanks to added plumbings, an extra pair of drop tanks for ferry flights. The F-94A/B’s machine gun pods as well as the F-94C’s unguided missile launchers could be mounted to the wings, too, making it a viable attack aircraft in a secondary role.
The USAF was highly interested in this update proposal for the outdated interceptors (almost 500 F-94A/Bs had been built) and ordered 100 RF-94B conversions with an option for 100 more – just when a severe (and superior) competitor entered the stage after a lot of development troubles: Republic’s RF-84F Thunderflash reconnaissance version. The first YRF-84F had already been completed in February 1952 and it had an overall slightly better performance than the RF-94B. However, it offered more internal space for reconnaissance systems and was able to carry up to fifteen cameras with the support of many automatized systems, so that it was a single seater. Being largely identical to the F-84F and sharing its technical and logistical infrastructures, the USAF decided on short notice to change its procurement decision and rather adopt the more modern and promising Thunderflash as its standard tactical reconnaissance aircraft. The RF-94B conversion order was reduced to the initial 100 aircraft, and to avoid operational complexity these aircraft were exclusively delivered to Air National Guardss that had experience with the F-94A/B to replace their obsolete RF-80As.
Gradual replacement lasted until 1958, and while the RF-94B’s performance was overall better than the RF-80A’s, it was still disappointing and not the expected tactical intelligence gathering leap forward. The airframe did not cope well with constant low-level operations, and the aircraft’s marginal speed and handling did not ensure its survivability. However, unlike the RF-84F, which suffered from frequent engine problems, the Stargazers’ J33 made them highly reliable platforms – even though the complex Tri-Metrogen device turned out to be capricious, so that it was soon replaced with up to three standard cameras.
For better handling and less drag esp. at low altitude, the F-94B’s large Fletcher type wingtip tanks were frequently replaced with smaller ones with about half capacity. It also became common practice to operate the RF-94Bs with only a crew of one, and from 1960 on the RF-94B was, thanks to its second seat, more and more used as a trainer before pilots mounted more potent reconnaissance aircraft like the RF-101 Voodoo, which eventually replaced the RF-94B in ANG service. The last RF-94B was phased out in 1968, and, unlike the RF-84F, it was not operated by any foreign air force.

The kit and its assembly:
This project was originally earmarked as a submission for the 2021 “Reconnaissance & Surveillance” group build at whatifmodellers.com, in the form of a Heller F-94B with a new nose section. The inspiration behind this build was the real-world EF-94C (s/n 50-963): a solitary conversion with a bulbous camera nose. However, the EF-94C was not a reconnaissance aircraft but rather a chase plane/camera ship for the Air Research and Development Command, hence its unusual designation with the suffix “E”, standing for “Exempt” instead of the more appropriate “R” for a dedicated recce aircraft. There also was another EF-94C, but this was a totally different kind of aircraft: an ejection seat testbed.
I had a surplus Heller F-94B kit in The Stash™ and it was built almost completely OOB and did – except for some sinkholes and standard PSR work – not pose any problem. In fact, the old Heller Starfire model is IMHO a pretty good representation of the aircraft. O.K., its age might show, but almost anything you could ask for at 1:72 scale is there, including a decent, detailed cockpit.
The biggest change was the new camera nose, and it was scratched from an unlikely donor part: it consists of a Matchbox B-17G tail gunner station, slimmed down by the gunner station glazing's width at the seam in the middle, and this "sandwich" was furthermore turned upside down. Getting the transitional sections right took lots of PSR, though, and I added some styrene profiles to integrate the new nose into the rest of the hull. It was unintentional, but the new nose profile reminds a lot of a RF-101 recce Voodoo, and there's, with the straight wings, a very F-89ish look to the aircraft now? There's also something F2H-2ish about the outlines?
The large original wing tip tanks were cut off and replaced with smaller alternatives from a Hasegawa A-37. Because it was easy to realize on this kit I lowered the flaps, together with open ventral air brakes. The cockpit was taken OOB, I just modified the work station on the rear seat and replaced the rubber sight protector for the WSO with two screens for a camera operator. Finally, the one-piece cockpit glazing was cut into two parts to present the model with an open canopy.
Painting and markings:
This was a tough decision: either an NMF finish (the natural first choice), an overall light grey anti-corrosive coat of paint, both with relatively colorful unit markings, or camouflage. The USAF’s earlier RF-80As carried a unique scheme in olive drab/neutral grey with a medium waterline, but that would look rather vintage on the F-94. I decided that some tactical camouflage would make most sense on this kind of aircraft and eventually settled for the USAF’s SEA scheme with reduced tactical markings, which – after some field tests and improvisations in Vietnam – became standardized and was officially introduced to USAF aircraft around 1965 as well as to ANG units.
Even though I had already built a camouflaged F-94 some time ago (a Hellenic aircraft in worn SEA colors), I settled for this route. The basic colors (FS 30219, 34227, 34279 and 36622) all came from Humbrol (118, 117, 116 and 28, respectively), and for the pattern I adapted the paint scheme of the USAF’s probably only T-33 in SEA colors: a trainer based on Iceland during the Seventies and available as a markings option in one of the Special Hobby 1:32 T-33 kits. The low waterline received a wavy shape, inspired by an early ANG RF-101 in SEA camouflage I came across in a book. The new SEA scheme was apparently applied with a lot of enthusiasm and properness when it was brand new, but this quickly vaned. As an extra, the wing tip tanks received black anti-glare sections on their inner faces and a black anti-glare panel was added in front of the windscreen - a decal from a T-33 aftermarket sheet. Beyond a black ink wash the model received some subtle panel post-shading, but rather to emphasize surface details than for serious weathering.
The cockpit became very dark grey (Revell 06) while the landing gear wells were kept in zinc chromate green primer (Humbrol 80, Grass Green), with bright red (Humbrol 60, Matt Red) cover interiors and struts and wheels in aluminum (Humbrol 56). The interior of the flaps and the ventral air brakes became red, too.
The decals/markings came from a Special Hobby 1:72 F-86H; there’s a dedicated ANG boxing of the kit that comes with an optional camouflaged aircraft of the NY ANG, the least unit to operate the “Sabre Hog” during the Seventies. Since this 138th TFS formerly operated the F-94A/B, it was a perfect option for the RF-94B! I just used a different Bu. No. code on the fin, taken from a PrintScale A/T-37 set, and most stencils were perocured from the scrap box.
After a final light treatment with graphite around the afterburner for a more metallic shine of the iron metallic (Revell 97) underneath, the kit was sealed with a coat of matt acrylic varnish (Italeri).
A camouflaged F-94 is an unusual sight, but it works very well. The new/longer nose considerably changes the aircraft's profile, and even though the change is massive, the "Crocodile" looks surprisingly plausible, if not believable! And, despite the long nose, the aircraft looks pretty sleek, especially in the air.
How hot has it been? Hot enough to keep the folks at the Paramount Theater in Downtown Charlottesville from changing the marquee! Captured just before a thunderstorm on a hot evening last week and processed in High Key to enhance the feeling of heat.
"For most of the middle of the 20th century, Charlottesville’s Paramount Theater had taken a leading role in the community. Created by Chicago architectural firm Rapp & Rapp, architects of The Paramount-Publix chain and its flagship theater in New York City’s Times Square, Charlottesville’s Paramount was part of the golden age of cinema.
With its Greek Revival-influenced façade, The Paramount’s exterior evokes an earlier time in Virginia’s history. With its octagonal auditorium chamber, delicate detailing, and neoclassical grandeur, the theater honors Charlottesville’s most famous son, Thomas Jefferson. Through details like painted tapestries, exquisite plaster moldings, and brass chandeliers, C.W. and George Rapp created a theater unlike any other they would design – one truly reflective of the community it would call home.
Following its Thanksgiving Eve 1931 opening, The Paramount became a landmark overnight. Even though the theater came along during the decline of the American movie palace, and two years after the stock market crash of 1929, The Paramount thrived.
As with most Southern theaters of the era, The Paramount operated for many years as a segregated building. The Third Street Entrance, originally intended for use by African-American patrons, is another feature setting the theater apart. With a level of decoration and elegance sized for the smaller scale, but not completely removed (as was often the case), the design of the Third Street Entrance is complimentary to – not divorced from – that of the building as a whole.
One of Charlottesville’s premiere destinations, The Paramount made movie-going a special experience. Audiences numbering in the thousands each week would come as much to escape into opulent surroundings as to watch a show. For four decades, the grand movie palace hosted scores of films, war bond drives, fashion shows, cartoons for kids, and popular rock and roll artists, entertaining multiple generations of area families.
The Paramount remained Charlottesville’s crown jewel until 1974 when its doors closed for good. Even as the lights dimmed on the marquee, the theater was not forgotten. Almost from that moment, efforts were launched to save the theater from real and constant threats of demolition.
In 1992, the non-profit Paramount Theater, Inc. purchased the building. With a grant from the City of Charlottesville, the work began. The initial project – restoring the Main Street marquee – was selected for maximum visibility. After the marquee’s structure and finishes were examined, microanalysis of the paint determined original colors. At midnight on that New Year’s Eve, the marquee’s lights shone brightly on Main Street for the first time in a decade. The Paramount seemed ready to begin life anew.
Progress continued with the hiring of Washington architectural firm Martinez & Johnson Architecture, in partnership with Charlottesville firm Bushman Dreyfus Architects. The 16.2 million dollar project includes not only the meticulous restoration of the theater, but also the creation of new facilities enabling The Paramount to step into its new role as a regional performing arts center – a modified fly loft, backstage areas, orchestra pit, and a three-story annex building with computerized box office, ballroom and meeting spaces, and a community rehearsal room.
Restored to its former glory, The Paramount Theater opened its doors to the public once more on December 15, 2004 – more than thirty years after it had closed."
Two Lockheed Martin F-35B Lightning II fighter jets have successfully landed on board HMS Queen Elizabeth for the first time, laying the foundations for the next 50 years of fixed wing aviation in support of the UK’s Carrier Strike Capability.
Royal Navy Commander, Nathan Gray, 41, made history by being the first to land on board HMS Queen Elizabeth, carefully maneuvering his stealth jet onto the thermal coated deck. He was followed by Royal Navy Squadron Leader Andy Edgell, RAF, both of whom are test pilots, operating with the Integrated Test Force (ITF) based at Naval Air Station Patuxent River, Maryland.
Shortly afterwards, once a deck inspection has been conducted and the all-clear given, Cmdr Gray became the first pilot to take off using the ship’s ski-ramp.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the Joint Strike Fighter (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.

Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.

From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the "Joint Strike Fighter" (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22
Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.

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 OV-10 Bronco was initially conceived in the early 1960s through an informal collaboration between W. H. Beckett and Colonel K. P. Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.
The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.
Beckett and Rice developed a basic platform meeting these requirements, then attempted to build a fiberglass prototype in a garage. The effort produced enthusiastic supporters and an informal pamphlet describing the concept. W. H. Beckett, who had retired from the Marine Corps, went to work at North American Aviation to sell the aircraft.
The aircraft's design supported effective operations from forward bases. The OV-10 had a central nacelle containing a crew of two in tandem and space for cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connected them at the fin tips. The OV-10 could perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.
The aircraft had responsive handling and could fly for up to 5½ hours with external fuel tanks. The cockpit had extremely good visibility for both pilot and co-pilot, provided by a wrap-around "greenhouse" that was wider than the fuselage. North American Rockwell custom ejection seats were standard, with many successful ejections during service. With the second seat removed, the OV-10 could carry 3,200 pounds (1,500 kg) of cargo, five paratroopers, or two litter patients and an attendant. Empty weight was 6,969 pounds (3,161 kg). Normal operating fueled weight with two crew was 9,908 pounds (4,494 kg). Maximum takeoff weight was 14,446 pounds (6,553 kg).
The bottom of the fuselage bore sponsons or "stub wings" that improved flight performance by decreasing aerodynamic drag underneath the fuselage. Normally, four 7.62 mm (.308 in) M60C machine guns were carried on the sponsons, accessed through large forward-opening hatches. The sponsons also had four racks to carry bombs, pods, or fuel. The wings outboard of the engines contained two additional hardpoints, one per side. Racked armament in the Vietnam War was usually seven-shot 2.75 in (70 mm) rocket pods with white phosphorus marker rounds or high-explosive rockets, or 5" (127 mm) four-shot Zuni rocket pods. Bombs, ADSIDS air-delivered/para-dropped unattended seismic sensors, Mk-6 battlefield illumination flares, and other stores were also carried.
Operational experience showed some weaknesses in the OV-10's design. It was significantly underpowered, which contributed to crashes in Vietnam in sloping terrain because the pilots could not climb fast enough. While specifications stated that the aircraft could reach 26,000 feet (7,900 m), in Vietnam the aircraft could reach only 18,000 feet (5,500 m). Also, no OV-10 pilot survived ditching the aircraft.
The OV-10 served in the U.S. Air Force, U.S. Marine Corps, and U.S. Navy, as well as in the service of a number of other countries. In U.S. military service, the Bronco was operated until the early Nineties, and obsoleted USAF OV-10s were passed on to the Bureau of Alcohol, Tobacco, and Firearms for anti-drug operations. A number of OV-10As furthermore ended up in the hands of the California Department of Forestry (CDF) and were used for spotting fires and directing fire bombers onto hot spots.
This was not the end of the OV-10 in American military service, though: In 2012, the type gained new attention because of its unique qualities. A $20 million budget was allocated to activate an experimental USAF unit of two airworthy OV-10Gs, acquired from NASA and the State Department. These machines were retrofitted with military equipment and were, starting in May 2015, deployed overseas to support Operation “Inherent Resolve”, flying more than 120 combat sorties over 82 days over Iraq and Syria. Their concrete missions remained unclear, and it is speculated they provided close air support for Special Forces missions, esp. in confined urban environments where the Broncos’ loitering time and high agility at low speed and altitude made them highly effective and less vulnerable than helicopters.
Furthermore, these Broncos reputedly performed strikes with the experimental AGR-20A “Advanced Precision Kill Weapons System (APKWS)”, a Hydra 70-millimeter rocket with a laser-seeking head as guidance - developed for precision strikes against small urban targets with little collateral damage. The experiment ended satisfactorily, but the machines were retired again, and the small unit was dissolved.
However, the machines had shown their worth in asymmetric warfare, and the U.S. Air Force decided to invest in reactivating the OV-10 on a regular basis, despite the overhead cost of operating an additional aircraft type in relatively small numbers – but development and production of a similar new type would have caused much higher costs, with an uncertain time until an operational aircraft would be ready for service. Re-activating a proven design and updating an existing airframe appeared more efficient.
The result became the MV-10H, suitably christened “Super Bronco” but also known as “Black Pony”, after the program's internal name. This aircraft was derived from the official OV-10X proposal by Boeing from 2009 for the USAF's Light Attack/Armed Reconnaissance requirement. Initially, Boeing proposed to re-start OV-10 manufacture, but this was deemed uneconomical, due to the expected small production number of new serial aircraft, so the “Black Pony” program became a modernization project. In consequence, all airframes for the "new" MV-10Hs were recovered OV-10s of various types from the "boneyard" at Davis-Monthan Air Force Base in Arizona.
While the revamped aircraft would maintain much of its 1960s-vintage rugged external design, modernizations included a completely new, armored central fuselage with a highly modified cockpit section, ejection seats and a computerized glass cockpit. The “Black Pony” OV-10 had full dual controls, so that either crewmen could steer the aircraft while the other operated sensors and/or weapons. This feature would also improve survivability in case of incapacitation of a crew member as the result from a hit.
The cockpit armor protected the crew and many vital systems from 23mm shells and shrapnel (e. g. from MANPADS). The crew still sat in tandem under a common, generously glazed canopy with flat, bulletproof panels for reduced sun reflections, with the pilot in the front seat and an observer/WSO behind. The Bronco’s original cargo capacity and the rear door were retained, even though the extra armor and defensive measures like chaff/flare dispensers as well as an additional fuel cell in the central fuselage limited the capacity. However, it was still possible to carry and deploy personnel, e. g. small special ops teams of up to four when the aircraft flew in clean configuration.
Additional updates for the MV-10H included structural reinforcements for a higher AUW and higher g load maneuvers, similar to OV-10D+ standards. The landing gear was also reinforced, and the aircraft kept its ability to operate from short, improvised airstrips. A fixed refueling probe was added to improve range and loiter time.
Intelligence sensors and smart weapon capabilities included a FLIR sensor and a laser range finder/target designator, both mounted in a small turret on the aircraft’s nose. The MV-10H was also outfitted with a data link and the ability to carry an integrated targeting pod such as the Northrop Grumman LITENING or the Lockheed Martin Sniper Advanced Targeting Pod (ATP). Also included was the Remotely Operated Video Enhanced Receiver (ROVER) to provide live sensor data and video recordings to personnel on the ground.
To improve overall performance and to better cope with the higher empty weight of the modified aircraft as well as with operations under hot-and-high conditions, the engines were beefed up. The new General Electric CT7-9D turboprop engines improved the Bronco's performance considerably: top speed increased by 100 mph (160 km/h), the climb rate was tripled (a weak point of early OV-10s despite the type’s good STOL capability) and both take-off as well as landing run were almost halved. The new engines called for longer nacelles, and their circular diameter markedly differed from the former Garrett T76-G-420/421 turboprop engines. To better exploit the additional power and reduce the aircraft’s audio signature, reversible contraprops, each with eight fiberglass blades, were fitted. These allowed a reduced number of revolutions per minute, resulting in less noise from the blades and their tips, while the engine responsiveness was greatly improved. The CT7-9Ds’ exhausts were fitted with muzzlers/air mixers to further reduce the aircraft's noise and heat signature.
Another novel and striking feature was the addition of so-called “tip sails” to the wings: each wingtip was elongated with a small, cigar-shaped fairing, each carrying three staggered, small “feather blade” winglets. Reputedly, this installation contributed ~10% to the higher climb rate and improved lift/drag ratio by ~6%, improving range and loiter time, too.
Drawing from the Iraq experience as well as from the USMC’s NOGS test program with a converted OV-10D as a night/all-weather gunship/reconnaissance platform, the MV-10H received a heavier gun armament: the original four light machine guns that were only good for strafing unarmored targets were deleted and their space in the sponsons replaced by avionics. Instead, the aircraft was outfitted with a lightweight M197 three-barrel 20mm gatling gun in a chin turret. This could be fixed in a forward position at high speed or when carrying forward-firing ordnance under the stub wings, or it could be deployed to cover a wide field of fire under the aircraft when it was flying slower, being either slaved to the FLIR or to a helmet sighting auto targeting system.
The original seven hardpoints were retained (1x ventral, 2x under each sponson, and another pair under the outer wings), but the total ordnance load was slightly increased and an additional pair of launch rails for AIM-9 Sidewinders or other light AAMs under the wing tips were added – not only as a defensive measure, but also with an anti-helicopter role in mind; four more Sidewinders could be carried on twin launchers under the outer wings against aerial targets. Other guided weapons cleared for the MV-10H were the light laser-guided AGR-20A and AGM-119 Hellfire missiles, the Advanced Precision Kill Weapon System upgrade to the light Hydra 70 rockets, the new Laser Guided Zuni Rocket which had been cleared for service in 2010, TV-/IR-/laser-guided AGM-65 Maverick AGMs and AGM-122 Sidearm anti-radar missiles, plus a wide range of gun and missile pods, iron and cluster bombs, as well as ECM and flare/chaff pods, which were not only carried defensively, but also in order to disrupt enemy ground communication.
In this configuration, a contract for the conversion of twelve mothballed American Broncos to the new MV-10H standard was signed with Boeing in 2016, and the first MV-10H was handed over to the USAF in early 2018, with further deliveries lasting into early 2020. All machines were allocated to the newly founded 919th Special Operations Support Squadron at Duke Field (Florida). This unit was part of the 919th Special Operations Wing, an Air Reserve Component (ARC) of the United States Air Force. It was assigned to the Tenth Air Force of Air Force Reserve Command and an associate unit of the 1st Special Operations Wing, Air Force Special Operations Command (AFSOC). If mobilized the wing was gained by AFSOC (Air Force Special Operations Command) to support Special Tactics, the U.S. Air Force's special operations ground force. Similar in ability and employment to Marine Special Operations Command (MARSOC), U.S. Army Special Forces and U.S. Navy SEALs, Air Force Special Tactics personnel were typically the first to enter combat and often found themselves deep behind enemy lines in demanding, austere conditions, usually with little or no support.
The MV-10Hs are expected to provide support for these ground units in the form of all-weather reconnaissance and observation, close air support and also forward air control duties for supporting ground units. Precision ground strikes and protection from enemy helicopters and low-flying aircraft were other, secondary missions for the modernized Broncos, which are expected to serve well into the 2040s. Exports or conversions of foreign OV-10s to the Black Pony standard are not planned, though.

The kit and its assembly:
This fictional Bronco update/conversion was simply spawned by the idea: could it be possible to replace the original cockpit section with one from an AH-1 Cobra, for a kind of gunship version?
The basis is the Academy OV-10D kit, mated with the cockpit section from a Fujimi AH-1S TOW Cobra (Revell re-boxing, though), chosen because of its “boxy” cockpit section with flat glass panels – I think that it conveys the idea of an armored cockpit section best. Combining these parts was not easy, though, even though the plan sound simple. Initially, the Bronco’s twin booms, wings and stabilizer were built separately, because this made PSR on these sections easier than trying the same on a completed airframe. One of the initial challenges: the different engines. I wanted something uprated, and a different look, and I had a pair of (excellent!) 1:144 resin engines from the Russian company Kompakt Zip for a Tu-95 bomber at hand, which come together with movable(!) eight-blade contraprops that were an almost perfect size match for the original three-blade props. Biggest problem: the Tu-95 nacelles have a perfectly circular diameter, while the OV-10’s booms are square and rectangular. Combining these parts and shapes was already a messy PST affair, but it worked out quite well – even though the result rather reminds of some Chinese upgrade measure (anyone know the Tu-4 copies with turboprops? This here looks similar!). But while not pretty, I think that the beafier look works well and adds to the idea of a “revived” aircraft. And you can hardly beat the menacing look of contraprops on anything...
The exotic, so-called “tip sails” on the wings, mounted on short booms, are a detail borrowed from the Shijiazhuang Y-5B-100, an updated Chinese variant/copy of the Antonov An-2 biplane transporter. The booms are simple pieces of sprue from the Bronco kit, the winglets were cut from 0.5mm styrene sheet.
For the cockpit donor, the AH-1’s front section was roughly built, including the engine section (which is a separate module, so that the basic kit can be sold with different engine sections), and then the helicopter hull was cut and trimmed down to match the original Bronco pod and to fit under the wing. This became more complicated than expected, because a) the AH-1 cockpit and the nose are considerably shorter than the OV-10s, b) the AH-1 fuselage is markedly taller than the Bronco’s and c) the engine section, which would end up in the area of the wing, features major recesses, making the surface very uneven – calling for massive PSR to even this out. PSR was also necessary to hide the openings for the Fujimi AH-1’s stub wings. Other issues: the front landing gear (and its well) had to be added, as well as the OV-10 wing stubs. Furthermore, the new cockpit pod’s rear section needed an aerodynamical end/fairing, but I found a leftover Academy OV-10 section from a build/kitbashing many moons ago. Perfect match!
All these challenges could be tackled, even though the AH-1 cockpit looks surprisingly stout and massive on the Bronco’s airframe - the result looks stockier than expected, but it works well for the "Gunship" theme. Lots of PSR went into the new central fuselage section, though, even before it was mated with the OV-10 wing and the rest of the model.
Once cockpit and wing were finally mated, the seams had to disappear under even more PSR and a spinal extension of the canopy had to be sculpted across the upper wing surface, which would meld with the pod’s tail in a (more or less) harmonious shape. Not an easy task, and the fairing was eventually sculpted with 2C putty, plus even more PSR… Looks quite homogenous, though.
After this massive body work, other hardware challenges appeared like small distractions. The landing gear was another major issue because the deeper AH-1 section lowered the ground clearance, also because of the chin turret. To counter this, I raised the OV-10’s main landing gear by ~2mm – not much, but it was enough to create a credible stance, together with the front landing gear transplant under the cockpit, which received an internal console to match the main landing gear’s length. Due to the chin turret and the shorter nose, the front wheel retracts backwards now. But this looks quite plausible, thanks to the additional space under the cockpit tub, which also made a belt feed for the gun’s ammunition supply believable.
To enhance the menacing look I gave the model a fixed refueling boom, made from 1mm steel wire and a receptor adapter sculpted with white glue. The latter stuff was also used add some antenna fairings around the hull. Some antennae, chaff dispensers and an IR decoy were taken from the Academy kit.
The ordnance came from various sources. The Sidewinders under the wing tips were taken from an Italeri F-16C/D kit, they look better than the missiles from the Academy Bronco kit. Their launch rails came from an Italeri Bae Hawk 200. The quadruple Hellfire launchers on the underwing hardpoints were left over from an Italeri AH-1W, and they are a perfect load for this aircraft and its role. The LAU-10 and -19 missile pods on the stub wings were taken from the OV-10 kit.
Painting and markings:
Finding a suitable and somewhat interesting – but still plausible – paint scheme was not easy. Taking the A-10 as benchmark, an overall light grey livery (with focus on low contrast against the sky as protection against ground fire) would have been a likely choice – and in fact the last operational American OV-10s were painted in this fashion. But in order to provide a different look I used the contemporary USAF V-22Bs and Special Operations MC-130s as benchmark, which typically carry a darker paint scheme consisting of FS 36118 (suitably “Gunship Gray” :D) from above, FS 36375 underneath, with a low, wavy waterline, plus low-viz markings. Not spectacular, but plausible – and very similar to the late r/w Colombian OV-10s.
The cockpit tub became Dark Gull Grey (FS 36231, Humbrol 140) and the landing gear white (Revell 301).
The model received an overall black ink washing and some post-panel-shading, to liven up the dull all-grey livery. The decals were gathered from various sources, and I settled for black USAF low-viz markings. The “stars and bars” come from a late USAF F-4, the “IP” tail code was tailored from F-16 markings and the shark mouth was taken from an Academy AH-64. Most stencils came from another Academy OV-10 sheet and some other sources.
Decals were also used to create the trim on the propeller blades and markings on the ordnance.
Finally, the model was sealed with a coat of matt acrylic varnish (Italeri) and some exhaust soot stains were added with graphite along the tail boom flanks.
A successful transplantation – but is this still a modified Bronco or already a kitbashing? The result looks quite plausible and menacing, even though the TOW Cobra front section appears relatively massive. But thanks to the bigger engines and extended wing tips the proportions still work. The large low-pressure tires look a bit goofy under the aircraft, but they are original. The grey livery works IMHO well, too – a more colorful or garish scheme would certainly have distracted from the modified technical basis.
In Vegas, it's very easy to get thirsty - especially during the summer. You'll want to drink water from just about anywhere. But after seeing these water features at Aria, all you'll want to do is stare.
Created by WET, the design firm responsible for the fountains at Bellagio and The Volcano at Mirage, these water features are another spectacular display on the Strip.
Once you pull up to Aria's porte-cochère, you'll immediately notice Lumia, a fountain featuring twisting ribbons and large arcs of streaming water. The splashes are in perfect sync, creating bold "water sparks" at their intersections. And here's something you don't see everyday: This is the first fountain ever to display bright neon colors in broad daylight. We're so used to seeing these colors at nighttime, but looking at Lumia during the day feels like your eyes are playing tricks on you. But make sure to check out Lumia at nighttime, too. The hot pink, green, purple and blue colors with the splashing water stand out even more.
With the resort's mission of being green, the water you see in Lumia is recycled and even has a computerized system that helps control splashing during windy days.

U.S. Air Force Capt. Andrew “Dojo” Olson, F-35 Demonstration Team pilot and commander, performs a dedication pass during the Melbourne Air and Space Show in Melbourne, Fla., March 30, 2019. During the two-day event, more than 50,000 guests attended the Melbourne Air and Space Show.
LUKE AIR FORCE BASE, Ariz. --
The Secretary of the Air Force selected Luke Air Force Base, Arizona, as a candidate to host a Belgium F-35A Foreign Military Sales Formal Training Unit, for up to seven years, starting in 2023.
“Because of Luke AFB's infrastructure and its experience in hosting international F-35 customers, Luke is uniquely suited to provide an optimal training environment for our Belgian Allies,” said Secretary of the Air Force Barbara Barrett. “Our partnership with Belgium has historic importance and will prove vital in our collective futures.”
The next step will be to complete a site survey at Luke AFB later this year to confirm it meets mission, capacity, environmental, and cost criteria which will be followed by the environmental impact analysis process.
In the future, the Air Force expects to identify an additional permanent F-35 Foreign Military Sales training base to support new customers.
From Wikipedia, the free encyclopedia
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather, stealth, fifth-generation, multirole combat aircraft, designed for ground-attack and air-superiority missions. It is built by Lockheed Martin and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.
The F-35 has three main models: the conventional takeoff and landing F-35A (CTOL), the short take-off and vertical-landing F-35B (STOVL), and the catapult-assisted take-off but arrested recovery, carrier-based F-35C (CATOBAR). The F-35 descends from the Lockheed Martin X-35, the design that was awarded the Joint Strike Fighter (JSF) program over the competing Boeing X-32. The official Lightning II name has proven deeply unpopular and USAF pilots have nicknamed it Panther, instead.
The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and formerly Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the "Joint Strike Fighter" (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms.
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes.
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system.
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft.
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency.
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.

The Arnold Arboretum of Harvard University is an arboretum located in the Jamaica Plain and Roslindale sections of Boston, Massachusetts. It was designed by Frederick Law Olmsted and is the second largest "link" in the Emerald Necklace.
History
The Arboretum was founded in 1872 when the President and Fellows of Harvard College became trustees of a portion of the estate of James Arnold (1781–1868).
In 1842, Benjamin Bussey (1757–1842), a prosperous Boston merchant and scientific farmer, donated his country estate Woodland Hill and a part of his fortune to Harvard University "for instruction in agriculture, horticulture, and related subjects". Bussey had inherited land from fellow patriot Eleazer Weld in 1800 and further enlarged his large estate between 1806 and 1837 by acquiring and consolidating various farms that had been established as early as the seventeenth century. Harvard used this land for the creation of the Bussey Institute, which was dedicated to agricultural experimentation. The first Bussey Institute building was completed in 1871 and served as headquarters for an undergraduate school of agriculture.
Sixteen years after Bussey's death, James Arnold, a New Bedford, Massachusetts whaling merchant, specified that a portion of his estate was to be used for "...the promotion of Agricultural, or Horticultural improvements". In 1872, when the trustees of the will of James Arnold transferred his estate to Harvard University, Arnold’s gift was combined with 120 acres (0.49 km2) of the former Bussey estate to create the Arnold Arboretum. In the deed of trust between the Arnold trustees and the College, income from Arnold’s legacy was to be used for establishing, developing and maintaining an arboretum to be known as the Arnold Arboretum which "shall contain, as far as practicable, all the trees [and] shrubs ... either indigenous or exotic, which can be raised in the open air of West Roxbury". The historical mission of the Arnold Arboretum is to increase knowledge of woody plants through research and to disseminate this knowledge through education.
Charles Sprague Sargent was appointed director and Arnold Professor of Botany shortly after the establishment of the institution in 1872.[2] Together with landscape architect Frederick Law Olmsted he developed the road and pathway system and delineated the collection areas by family and genus, following the then current and widely accepted classification system of Bentham and Hooker. The Hunnewell building was designed by architect Alexander Wadsworth Longfellow, Jr. in 1892 and constructed with funds donated by H. H. Hunnewell in 1903. From 1946 to 1950 the landscape architect Beatrix Farrand was the landscape design consultant for the Arboretum. Her early training in the 1890s included time with Charles Sprague Sargent and chief propagator and superintendent Jackson Thornton Johnson.[3] Today the Arboretum occupies 265 acres (107 hectares) of land divided between four parcels, viz. the main Arboretum and the Peters Hill, Weld-Walter and South Street tracts. The collections, however, are located primarily in the main Arboretum and on the Peters Hill tract. The Arboretum remains one of the finest examples of a landscape designed by Frederick Law Olmsted and it is a Frederick Law Olmsted National Historic Site) and a National Historic Landmark.
Robert E. Cook is the seventh and current Director of the Arnold Arboretum. He is also the Director of the Harvard University Herbaria located in Cambridge, Massachusetts.
Status
The Arboretum is privately endowed as a department of Harvard University. The land, however, was deeded to the City of Boston in 1882 and incorporated into the so-called "Emerald Necklace". Under the agreement with the City, Harvard University was given a thousand-year lease on the property, and the University, as trustee, is directly responsible for the development, maintenance, and operation of the Arboretum; the City retains responsibility for water fountains, benches, roads, boundaries, and policing. The annual operating budget of $7,350,644 (fiscal year 2003) is largely derived from endowment, which is also managed by the University, and all Arboretum staff are University employees. Other income is obtained through granting agencies and contributors.
Location
The main Arborway gate is located on Route 203 a few hundred yards south of its junction with the Jamaicaway. Public transportation to the Arboretum is available on the MBTA Orange Line to its terminus at Forest Hills Station and by bus (#39) to the Monument in Jamaica Plain. The Arboretum is within easy walking distance from either of these points.
Hours
The grounds are open free of charge to the public from sunrise to sunset 365 days of the year. The Visitor's Center in the Hunnewell Building, 125 Arborway, is open Monday through Friday 9 a.m.–4 p.m.; Saturdays 10 a.m.–4 p.m.; Sundays 12 p.m.–4 PM. The Visitor’s Center is closed on holidays. The Library, located in the Hunnewell Building, is open Monday through Saturday, 10 a.m.–4 p.m.. The Library is closed on Sundays and holidays. Stacks are closed and the collection does not circulate.
Area
Two hundred and sixty-five acres (107 hectares) in the Jamaica Plain and Roslindale sections of Boston, Massachusetts, located at 42°19′N 71°5′W / 42.317°N 71.083°W / 42.317; -71.083, with altitudes ranging from 46 feet (15 m) in the meadow across the drive from the Hunnewell Building to 240 feet (79 m) at the top of Peters Hill.
Climate
Average yearly rainfall is 43.63 inches (1,102 mm); average snowfall, 40.2 inches (102 centimeters). Monthly mean temperature is 51.5 °F (10.8 °C); July's mean temperature is 73.5 °F (23 °C); January's is 29.6 °F (-1.3 °C). The Arboretum is located in USDA hardiness zone 6 (0 to −10 °F, −18 to −23 °C).
Collections (as of September 14, 2007)
At present, the living collections include 15,441 individual plants (including nursery holdings) belonging to 10,216 accessions representing 4,099 taxa; with particular emphasis on the ligneous species of North America and eastern Asia. Historic collections include the plant introductions from eastern Asia made by Charles Sprague Sargent, Ernest Henry Wilson, William Purdom, Joseph Hers, and Joseph Rock. Recent introductions from Asia have resulted from the 1977 Arnold Arboretum Expedition to Japan and Korea, the 1980 Sino-American Botanical Expedition to western Hubei Province, and more recent expeditions to China and Taiwan.
Comprehensive collections are maintained and augmented for most genera, and genera that have received particular emphasis include: Acer, Fagus, Carya, Forsythia, Taxodium, Pinus, Metasequoia, Lonicera, Magnolia, Malus, Quercus, Rhododendron, Syringa, Paulownia, Albizia, Ilex, Gleditsia and Tsuga. Other comprehensive collections include the Bradley Collection of Rosaceous Plants, the collection of conifers and dwarf conifers, and the Larz Anderson Bonsai Collection. Approximately 500 accessions are processed annually.
Collections policy
The mission of the Arnold Arboretum is to increase our knowledge of the evolution and biology of woody plants. Historically, this research has investigated the global distribution and evolutionary history of trees, shrubs and vines, with particular emphasis on the disjunct species of East Asia and North America. Today this work continues through molecular studies of the evolution and biogeography of the floras of temperate Asia, North America and Europe.
Research activities include molecular studies of gene evolution, investigations of plant-water relations, and the monitoring of plant phenology, vegetation succession, nutrient cycling and other factors that inform studies of environmental change. Applied work in horticulture uses the collections for studies in plant propagation, plant introduction, and environmental management. This diversity of scientific investigation is founded in a continuing commitment to acquire, grow, and document the recognized species and infraspecific taxa of ligneous plants of the Northern Hemisphere that are able to withstand the climate of the Arboretum’s 265-acre (1.07 km2) Jamaica Plain/Roslindale site.
As a primary resource for research in plant biology, the Arboretum’s living collections are actively developed, curated, and managed to support scientific investigation and study. To this end, acquisition policies place priority on obtaining plants that are genetically representative of documented wild populations. For each taxon, the Arnold Arboretum aspires to grow multiple accessions of known wild provenance in order to represent significant variation that may occur across the geographic range of the species. Accessions of garden or cultivated provenance are also acquired as governed by the collections policies herein.
For all specimens, full documentation of both provenance and history within the collection is a critical priority. Curatorial procedures provide for complete and accurate records for each accession, and document original provenance, locations in the collections, and changes in botanical identity. Herbarium specimens, DNA materials, and digital images are gathered for the collection and maintained in Arboretum data systems and the herbarium at the Roslindale site.
Research
Research on plant pathology and integrated pest management for maintenance of the living collections is constantly ongoing. Herbarium-based research focuses on the systematics and biodiversity of both temperate and tropical Asian forests, as well as the ecology and potential for sustainable use of their resources. The Arboretum's education programs offer school groups and the general public a wide range of lectures, courses, and walks focusing on the ecology and cultivation of plants. Its quarterly magazine, Arnoldia, provides in-depth information on horticulture, botany, and garden history. Current Research Initiatives
Plant Records
Plant records are maintained on a computerized database, BG-BASE 6.8 (BG-Base Inc.), which was initiated in 1985 at the request of the Arnold Arboretum and the Threatened Plants Unit (TPU) of the World Conservation Monitoring Centre (WCMC). A computerized mapping program (based on AutoCAD (Autodesk)) is linked to BG-BASE, and each accession is recorded on a series of maps at a scale of 1-inch (25 mm) to 20 feet (1:240) or 1-inch (25 mm) to 10 feet (1:120). A computer-driven embosser generates records labels. All accessioned plants in the collections are labeled with accession number, botanical name, and cultivar name (when appropriate), source information, common name, and map location. Trunk and/or display labels are also hung on many accessions and include botanical and common names and nativity. Stake labels are used to identify plants located in the Leventritt Garden and Chinese Path.
Grounds Maintenance
The grounds staff consists of the superintendent and assistant superintendent, three arborists, and ten horticultural technologists. A service garage is adjacent to the Hunnewell Building, where offices and locker rooms are located. During the summer months ten horticultural interns supplement the grounds staff. A wide array of vehicles and modern equipment, including an aerial lift truck and a John Deere backhoe and front loader, are used in grounds maintenance. Permanent grounds staff, excluding the superintendents, are members of AFL/CIO Local 615, Service Employees International Union (SEIU).
Nursery and Greenhouse Facilities
The Dana Greenhouses, located at 1050 Centre Street (with a mailing address of 125 Arborway), were completed in 1962. They comprise four service greenhouses totaling 3,744 square feet (348 m²), the headhouse with offices, cold rooms, storage areas, and a classroom. Staffing at the greenhouse includes the manager of greenhouses and nurseries, the plant propagator, two assistants, and, during the summer months, two horticultural interns. Adjacent to the greenhouse is a shade house of 3,150 square feet (293 m²), a 12,600 cubic foot (357 m³) cold storage facility, and three irrigated, inground nurseries totaling approximately one and one-half acres (6,000 m²). Also located in the greenhouse complex is the bonsai pavilion, where the Larz Anderson Bonsai Collection is displayed from the middle of April to the end of October. During the winter months the bonsai are held in the cold storage unit at temperatures slightly above freezing.
Isabella Welles Hunnewell Internship Program
The living collections department of the Arnold Arboretum offers a paid summer internship program [2] that combines hands-on training in horticulture with educational courses. Intern trainees will be accepted for 12- to 24-week appointments. Ten interns will work with the grounds maintenance department and two in the Dana Greenhouses.
As part of the training program, interns participate in mandatory instructional sessions and field trips in order to develop a broader sense of the Arboretum’s horticultural practices as well as those of other institutions. Sessions and field trips are led by Arnold staff members and embrace an open question and answer format encouraging all to participate. Interns often bring experience and knowledge that everyone, including staff, benefits from. It is a competitive-free learning environment.
Horticultural Apprenticeship
The Arboretum created the horticultural apprenticeship program in 1997 to provide hands-on experience in all aspects of the development, curation, and maintenance of the Arboretum's living collections to individuals interested in pursuing a career in an arboretum or botanical garden.
The Living Collections department of the Arnold Arboretum offers a summer internship program[4] that combines practical hands-on training in horticulture with educational courses. Fourteen Interns/Horticultural Trainees are accepted for twelve to twenty-four week appointments. Interns receive the majority of their training in one of three departments: Grounds Maintenance, Nursery and Greenhouse, or Plant Records.
Lilac Sunday
The second Sunday in May every year is "Lilac Sunday". This is the only day of the year that picnicing is allowed. In 2008, on the 100th anniversary of Lilac Sunday, the Arboretum website touted:
Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a daylong celebration. On Lilac Sunday, garden enthusiasts from all over New England gather at the Arboretum to picnic, watch Morris dancing, and tour the lilac collection. On the day of the event, which takes place rain or shine, the Arboretum is open as usual from dawn to dusk.[5]
Associated Collections
The Arboretum's herbarium in Jamaica Plain holds specimens of cultivated plants that relate to the living collections (ca. 160,000). The Jamaica Plain herbarium, horticultural library, archives, and photographs are maintained in the Hunnewell building at 125 Arborway; however, the main portions of the herbarium and library collections are housed in Cambridge on the campus of Harvard University, at 22 Divinity Avenue.
Publications
The inventory of living collections is updated periodically and made available to sister botanical gardens and arboreta on request; it is also available on the Arboretum’s website (searchable inventory). Arnoldia, the quarterly magazine of the Arnold Arboretum, frequently publishes articles relating to the living collections. A Reunion of Trees[6] by Stephen A. Spongberg (curator emeritus) recounts the history of the introduction of many of the exotic species included in the Arobretum’s collections. New England Natives[7] written by horticultural research archivist Sheila Connor describes many of the trees and shrubs of the New England flora and the ways New Englanders have used them since prehistoric times. Science in the Pleasure Ground[8] by Ida Hay (former curatorial associate) constitutes an institutional biography of the Arboretum.
Institutional Collaborations
The Arboretum maintains an institutional membership in the American Public Garden Association (APGA) and the International Association of Botanical Gardens and Arboreta. Additionally, members of the staff are associated with many national and international botanical and horticultural organizations. The Arboretum is also a cooperating institution with the Center for Plant Conservation (CPC), and as an active member of the North American Plant Collections Consortium (NAPCC), it is committed to broadening and maintaining its holdings of: Acer, Carya, Fagus, Stewartia, Syringa, and Tsuga for the purposes of plant conservation, evaluation, and research. The Arboretum is also a member of the North American China Plant Exploration Consortium (NACPEC).

These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey was the sole supplier of several F-35 parts until its removal from the program in July 2019. Several other countries have ordered, or are considering ordering, the aircraft.
As the largest and most expensive military program ever, the F-35 became the subject of much scrutiny and criticism in the U.S. and in other countries. In 2013 and 2014, critics argued that the plane was "plagued with design flaws", with many blaming the procurement process in which Lockheed was allowed "to design, test, and produce the F-35 all at the same time," instead of identifying and fixing "defects before firing up its production line". By 2014, the program was "$163 billion over budget [and] seven years behind schedule". Critics also contend that the program's high sunk costs and political momentum make it "too big to kill".
The F-35 first flew on 15 December 2006. In July 2015, the United States Marines declared its first squadron of F-35B fighters ready for deployment. However, the DOD-based durability testing indicated the service life of early-production F-35B aircraft is well under the expected 8,000 flight hours, and may be as low as 2,100 flight hours. Lot 9 and later aircraft include design changes but service life testing has yet to occur. The U.S. Air Force declared its first squadron of F-35As ready for deployment in August 2016. The U.S. Navy declared its first F-35Cs ready in February 2019. In 2018, the F-35 made its combat debut with the Israeli Air Force.
The U.S. stated plan is to buy 2,663 F-35s, which will provide the bulk of the crewed tactical airpower of the U.S. Air Force, Navy, and Marine Corps in coming decades. Deliveries of the F-35 for the U.S. military are scheduled until 2037 with a projected service life up to 2070.
Development
F-35 development started in 1992 with the origins of the "Joint Strike Fighter" (JSF) program and was to culminate in full production by 2018. The X-35 first flew on 24 October 2000 and the F-35A on 15 December 2006.
The F-35 was developed to replace most US fighter jets with the variants of a single design that would be common to all branches of the military. It was developed in co-operation with a number of foreign partners, and, unlike the F-22 Raptor, intended to be available for export. Three variants were designed: the F-35A (CTOL), the F-35B (STOVL), and the F-35C (CATOBAR). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017, the effective commonality was only 20%. The program received considerable criticism for cost overruns during development and for the total projected cost of the program over the lifetime of the jets.
By 2017, the program was expected to cost $406.5 billion over its lifetime (i.e. until 2070) for acquisition of the jets, and an additional $1.1 trillion for operations and maintenance. A number of design deficiencies were alleged, such as: carrying a small internal payload; performance inferior to the aircraft being replaced, particularly the F-16; lack of safety in relying on a single engine; and flaws such as the vulnerability of the fuel tank to fire and the propensity for transonic roll-off (wing drop). The possible obsolescence of stealth technology was also criticized.
Design
Overview
Although several experimental designs have been developed since the 1960s, such as the unsuccessful Rockwell XFV-12, the F-35B is to be the first operational supersonic STOVL stealth fighter. The single-engine F-35 resembles the larger twin-engined Lockheed Martin F-22 Raptor, drawing design elements from it. The exhaust duct design was inspired by the General Dynamics Model 200, proposed for a 1972 supersonic VTOL fighter requirement for the Sea Control Ship.
Lockheed Martin has suggested that the F-35 could replace the USAF's F-15C/D fighters in the air-superiority role and the F-15E Strike Eagle in the ground-attack role. It has also stated the F-35 is intended to have close- and long-range air-to-air capability second only to that of the F-22 Raptor, and that the F-35 has an advantage over the F-22 in basing flexibility and possesses "advanced sensors and information fusion".
Testifying before the House Appropriations Committee on 25 March 2009, acquisition deputy to the assistant secretary of the Air Force, Lt. Gen. Mark D. "Shack" Shackelford, stated that the F-35 is designed to be America's "premier surface-to-air missile killer, and is uniquely equipped for this mission with cutting-edge processing power, synthetic aperture radar integration techniques, and advanced target recognition".
Improvements
Ostensible improvements over past-generation fighter aircraft include:
Durable, low-maintenance stealth technology, using structural fiber mat instead of the high-maintenance coatings of legacy stealth platforms.
Integrated avionics and sensor fusion that combine information from off- and on-board sensors to increase the pilot's situational awareness and improve target identification and weapon delivery, and to relay information quickly to other command and control (C2) nodes.
High-speed data networking including IEEE 1394b and Fibre Channel (Fibre Channel is also used on Boeing's Super Hornet.
The Autonomic Logistics Global Sustainment, Autonomic Logistics Information System (ALIS), and Computerized maintenance management system to help ensure the aircraft can remain operational with minimal maintenance manpower The Pentagon has moved to open up the competitive bidding by other companies. This was after Lockheed Martin stated that instead of costing 20% less than the F-16 per flight hour, the F-35 would actually cost 12% more. Though the ALGS is intended to reduce maintenance costs, the company disagrees with including the cost of this system in the aircraft ownership calculations. The USMC has implemented a workaround for a cyber vulnerability in the system. The ALIS system currently requires a shipping-container load of servers to run, but Lockheed is working on a more portable version to support the Marines' expeditionary operations.
Electro-hydrostatic actuators run by a power-by-wire flight-control system.
A modern and updated flight simulator, which may be used for a greater fraction of pilot training to reduce the costly flight hours of the actual aircraft.
Lightweight, powerful lithium-ion batteries to provide power to run the control surfaces in an emergency.
Structural composites in the F-35 are 35% of the airframe weight (up from 25% in the F-22). The majority of these are bismaleimide and composite epoxy materials. The F-35 will be the first mass-produced aircraft to include structural nanocomposites, namely carbon nanotube-reinforced epoxy. Experience of the F-22's problems with corrosion led to the F-35 using a gap filler that causes less galvanic corrosion to the airframe's skin, designed with fewer gaps requiring filler and implementing better drainage. The relatively short 35-foot wingspan of the A and B variants is set by the F-35B's requirement to fit inside the Navy's current amphibious assault ship parking area and elevators; the F-35C's longer wing is considered to be more fuel efficient.
Costs
A U.S. Navy study found that the F-35 will cost 30 to 40% more to maintain than current jet fighters, not accounting for inflation over the F-35's operational lifetime. A Pentagon study concluded a $1 trillion maintenance cost for the entire fleet over its lifespan, not accounting for inflation. The F-35 program office found that as of January 2014, costs for the F-35 fleet over a 53-year lifecycle was $857 billion. Costs for the fighter have been dropping and accounted for the 22 percent life cycle drop since 2010. Lockheed stated that by 2019, pricing for the fifth-generation aircraft will be less than fourth-generation fighters. An F-35A in 2019 is expected to cost $85 million per unit complete with engines and full mission systems, inflation adjusted from $75 million in December 2013.

I have had a good(?) time to wonder which kind projects would be nice with stepper motor(s). For some reasons from the pre-history of mankind I have had a preowned slide rail for videography (maybe for photography, too). Almost every camera available nowadays can be used for shooting videos. Also I have got experience: I've shot a couple strips - by pressing accidentally the video release knob.
In this case the camera should be moved manually from point A to point B on the rails - not so practical. So would it be motorized or even computerized? Apparently yes with some bagfulls of electronics and mechanics...
The Postcard

Crystal Skulls
Crystal skulls are human skull carvings made of clear or milky white quartz (also called "rock crystal"), claimed to be pre-Columbian Mesoamerican artifacts by their alleged finders.
However, these claims have been refuted for all of the specimens made available for scientific studies. The results of these studies demonstrated that those examined were manufactured in the mid-19th. century or later, almost certainly in Europe, during a time when interest in ancient culture abounded.
The skulls appear to have been crafted in Germany, probably at workshops in the town of Idar-Oberstein, which was renowned for crafting objects made from imported Brazilian quartz in the late 19th. century.
Despite various claims, legends of crystal skulls with mystical powers do not figure in genuine Mesoamerican or other Native American mythologies and spiritual accounts.
The skulls are often claimed to exhibit paranormal phenomena, and have often been portrayed as such in fiction. Crystal skulls have been a popular subject, appearing in numerous science fiction television series, novels, films, and video games.
Collections
Trade in fake pre-Columbian artifacts developed during the late 19th. century to the extent that in 1886, Smithsonian archaeologist William Henry Holmes wrote an article called "The Trade in Spurious Mexican Antiquities" for Science.
Although museums had acquired skulls earlier, it was Eugène Boban, an antiquities dealer who opened his shop in Paris in 1870, who is most associated with 19th.-century museum collections of crystal skulls. Most of Boban's collection, including three crystal skulls, was sold to the ethnographer Alphonse Pinart, who donated the collection to the Trocadéro Museum, which later became the Musée de l'Homme.
Research Into Crystal Skulls
Many crystal skulls are claimed to be pre-Columbian, usually attributed to the Aztec or Maya civilizations. Mesoamerican art has numerous representations of skulls, but none of the skulls in museum collections come from documented excavations.
Research carried out on several crystal skulls at the British Museum in 1967, 1996 and 2004 shows that the indented lines marking the teeth (for these skulls had no separate jawbone, unlike the Mitchell-Hedges skull) were carved using jeweler's equipment (rotary tools) developed in the 19th. century, making a pre-Columbian origin impossible.
The type of crystal was determined by examination of chlorite inclusions. It is only found in Madagascar and Brazil, and thus unobtainable or unknown within pre-Columbian Mesoamerica. The study concluded that the skulls were crafted in the 19th. century in Germany, quite likely at workshops in the town of Idar-Oberstein.
The crystal skulls in the British Museum and Paris's Musée de l'Homme were originally sold by the French antique dealer Eugène Boban, who was operating in Mexico City between 1860 and 1880.
The British Museum crystal skull transited through New York's Tiffany & Co., while the Musée de l'Homme's crystal skull was donated by Alphonse Pinart.
In 1992 the Smithsonian Institution investigated a crystal skull provided by an anonymous source; the source claimed to have purchased it in Mexico City in 1960, and that it was of Aztec origin. The investigation concluded that this skull was also made recently. According to the Smithsonian, Boban acquired his crystal skulls from sources in Germany, aligning with conclusions made by the British Museum.
The Journal of Archaeological Science published a detailed study by the British Museum and the Smithsonian in May 2008. Using electron microscopy and X-ray crystallography, a team of British and American researchers found that the British Museum skull was worked with a harsh abrasive substance such as corundum or diamond, and shaped using a rotary disc tool.
The Smithsonian specimen had been worked with a different abrasive, namely the silicon-carbon compound carborundum (Silicon carbide) which is a synthetic substance manufactured using modern industrial techniques. Since the synthesis of carborundum dates only to the 1890's and its wider availability to the 20th. century, the researchers concluded that:
"The suggestion is that it was
made in the 1950's or later".
The British Museum Skull
The crystal skull of the British Museum (shown in the photograph) first appeared in 1881, in the shop of the Paris antiquarian, Eugène Boban. Its origin was not stated in his catalogue of the time. He is said to have tried to sell it to Mexico's national museum as an Aztec artifact, but was unsuccessful.
Boban later moved his business to New York City, where the skull was sold to George H. Sisson. It was exhibited at a meeting of the American Association for the Advancement of Science in New York City in 1887 by George F. Kunz.
It was then sold at auction, and bought by Tiffany and Co., who later sold it at cost to the British Museum in 1897. The skull is very similar to the Mitchell-Hedges skull, although it is less detailed and does not have a movable lower jaw.
The British Museum catalogues the skull's provenance as "probably European, 19th. century AD," and describes it as "not an authentic pre-Columbian artefact". It has been established that this skull was made with modern tools, and that it is not authentic.
The Mitchell-Hedges Skull
The most famous and enigmatic skull was allegedly discovered in 1924 by Anna Mitchell-Hedges, adopted daughter of British adventurer and popular author F. A. Mitchell-Hedges.
It is the subject of a video documentary made in 1990, 'Crystal Skull of Lubaantun.'
It was examined and described by Smithsonian researchers as:
"Very nearly a replica of the British
Museum skull – almost exactly the
same shape, but with more detailed
modeling of the eyes and the teeth."
Mitchell-Hedges claimed that she found the skull buried under a collapsed altar inside a temple in Lubaantun, in British Honduras, now Belize. As far as can be ascertained, F. A. Mitchell-Hedges himself made no mention of the alleged discovery in any of his writings on Lubaantun.
Others present at the time of the excavation recorded neither the skull's discovery nor Anna's presence at the dig.
Recent evidence has come to light showing that F. A. Mitchell-Hedges purchased the skull at a Sotheby's auction in London on the 15th. October 1943, from London art dealer Sydney Burney. In December 1943, F. A. Mitchell-Hedges disclosed his purchase of the skull in a letter to his brother, stating plainly that he acquired it from Burney.
The skull is made from a block of clear quartz about the size of a small human cranium, measuring some 5 inches (13 cm) high, 7 inches (18 cm) long and 5 inches (13 cm) wide. The lower jaw is detached.
In the early 1970's it came under the temporary care of freelance art restorer Frank Dorland, who claimed upon inspecting it that it had been "carved" with total disregard to the natural crystal axis, and without the use of metal tools.
Dorland reported being unable to find any tell-tale scratch marks, except for traces of mechanical grinding on the teeth, and he speculated that it was first chiseled into rough form, probably using diamonds, and the finer shaping, grinding and polishing was achieved through the use of sand over a period of 150 to 300 years.
He said it could be up to 12,000 years old. Although various claims have been made over the years regarding the skull's physical properties, such as an allegedly constant temperature of 70 °F (21 °C), Dorland reported that there was no difference in properties between it and other natural quartz crystals.
While in Dorland's care the skull came to the attention of writer Richard Garvin, at the time working at an advertising agency where he supervised Hewlett-Packard's advertising account.
Garvin made arrangements for the skull to be examined at Hewlett-Packard's crystal laboratories in Santa Clara, California, where it was subjected to several tests. The labs determined only that it was not a composite as Dorland had supposed, but that it was fashioned from a single crystal of quartz.
The laboratory test also established that the lower jaw had been fashioned from the same left-handed growing crystal as the rest of the skull. No investigation was made by Hewlett-Packard as to its method of manufacture or dating.
As well as the traces of mechanical grinding on the teeth noted by Dorland, Mayanist archaeologist Norman Hammond reported that the holes (presumed to be intended for support pegs) showed signs of being made by drilling with metal.
Anna Mitchell-Hedges refused subsequent requests to submit the skull for further scientific testing.
The earliest published reference to the skull is the July 1936 issue of the British anthropological journal Man, where it was described as being in the possession of Sydney Burney, a London art dealer who was said to have owned it since 1933, and from whom evidence suggests that F. A. Mitchell-Hedges purchased it.
F. A. Mitchell-Hedges mentioned the skull only briefly in the first edition of his autobiography, Danger My Ally (1954), without specifying where or by whom it was found. He merely claimed that:
"It is at least 3,600 years old, and according to
legend it was used by the High Priest of the
Maya when he was performing esoteric rites.
It is said that when he willed death with the
help of the skull, death invariably followed".
All subsequent editions of Danger My Ally omitted mention of the skull entirely.
In a 1970 letter, Anna stated that:
"I was told by the few remaining Maya that
the skull was used by the high priest to will
death."
For this reason, the artifact is sometimes referred to as "The Skull of Doom".
Anna Mitchell-Hedges toured with the skull from 1967, exhibiting it on a pay-per-view basis. Somewhere between 1988 and 1990 she toured with the skull. She continued to grant interviews about the artifact until her death.
In her last eight years, Anna Mitchell-Hedges lived in Chesterton, Indiana, with Bill Homann, whom she married in 2002. She died on the 11th. April 2007.
Since her death, the Mitchell-Hedges Skull has been owned by Homann who continues to believe in its mystical properties.
In November 2007, Homann took the skull to the office of anthropologist Jane MacLaren Walsh, in the Smithsonian's National Museum of Natural History for examination.
Walsh carried out a detailed examination of the skull using ultraviolet light, a high-powered light microscope, and computerized tomography.
Homann took the skull to the museum again in 2008 so it could be filmed for a Smithsonian Networks documentary, Legend of the Crystal Skull, and on this occasion, Walsh was able to take two sets of silicone molds of surface tool marks for scanning electron microscope (SEM) analysis.
The SEM micrographs revealed evidence that the crystal had been worked with a high speed, hard metal rotary tool coated with a hard abrasive, such as diamond.
Walsh's extensive research on artifacts from Mexico and Central America showed that pre-contact artisans carved stone by abrading the surface with stone or wooden tools, and in later pre-Columbian times, copper tools, in combination with a variety of abrasive sands or pulverized stone.
These examinations led Walsh to the conclusion that the skull was probably carved in the 1930's, and was most likely based on the British Museum skull which had been exhibited fairly continuously from 1898.
In the National Geographic Channel documentary, "The Truth Behind the Crystal Skulls", forensic artist Gloria Nusse performed a forensic facial reconstruction over a replica of the skull. According to Nusse, the resulting face had female and European characteristics.
As it was hypothesized that the Crystal Skull was a replica of an actual human skull, the conclusion was that it could not have been created by ancient Americans.
The Paris Skull
The largest of the three skulls sold by Eugène Boban to Alphonse Pinart (sometimes called the Paris Skull), is about 10 cm (4 in) high. It has a hole drilled vertically through its center.
It is part of a collection held at the Musée du Quai Branly, and was subjected to scientific tests carried out in 2007–08 by France's Centre for Research and Restoration of the Museums in France. After a series of analyses carried out over three months, engineers concluded that:
"It is certainly not pre-Columbian. It shows
traces of polishing and abrasion by modern
tools."
Particle accelerator tests also revealed occluded traces of water that were dated to the 19th. century, and the Quai Branly released a statement that the tests seem to indicate that it was made late in the 19th century.
In 2009 the researchers published results of further investigations to establish when the Paris skull had been carved. Scanning electron microscopy analysis indicated the use of lapidary machine tools in its carving.
The results of a new dating technique known as quartz hydration dating (QHD) demonstrated that the Paris skull had been carved later than a reference quartz specimen artifact, known to have been cut in 1740.
The researchers concluded that the SEM and QHD results, combined with the skull's known provenance, indicate that it was carved in the 18th. or 19th. century.
The Smithsonian Skull
The Smithsonian Skull in the collections of the Department of Anthropology, National Museum of Natural History, was mailed to the Smithsonian Institution anonymously in 1992, and was claimed to be an Aztec object by its donor, and was purportedly from the collection of Porfirio Diaz.
It is the largest of the skulls, weighing 31 pounds (14 kg) and is 15 inches (38 cm) high. It was carved using carborundum, a modern abrasive. It has been displayed as a modern fake at the National Museum of Natural History.
Paranormal Claims and Spiritual Associations
Some individuals believe in the paranormal claim that crystal skulls can produce a variety of miracles. Anna Mitchell-Hedges claimed that the skull she allegedly discovered could cause visions and cure cancer.
She also claimed that she once used its magical properties to kill a man, and that in another instance, she saw in it a premonition of the John F. Kennedy assassination.
In the 1931 play The Satin Slipper by Paul Claudel, King Philip II of Spain uses a death's head made from a single piece of rock crystal lit by a ray of the setting sun to see the defeat of the Spanish Armada in its attack on the Kingdom of England.
Claims of the healing and supernatural powers of crystal skulls have had no support in the scientific community, which has found no evidence of any unusual phenomena associated with the skulls, nor any reason for further investigation, other than the confirmation of their provenance and method of manufacture.
Another novel and historically unfounded speculation ties in the legend of the crystal skulls with the completion of the previous Maya calendar b'ak'tun-cycle on the 21st. December 2012, claiming the re-uniting of the thirteen mystical skulls will forestall a catastrophe allegedly predicted by the ending of this calendar.
An airing of this claim appeared (among an assortment of others made) in The Mystery of the Crystal Skulls, a 2008 program produced for the Sci Fi Channel in May and shown on Discovery Channel Canada in June. Interviewees included Richard Hoagland, who attempted to link the skulls and the Maya to life on Mars, and David Hatcher Childress, proponent of lost Atlantean civilizations and anti-gravity claims.
Crystal skulls are also referred to by author Drunvalo Melchizedek in his book Serpent of Light. He writes that he came across indigenous Mayan descendants in possession of crystal skulls at ceremonies at temples in the Yucatán, which he writes contained souls of ancient Mayans who had entered the skulls to await the time when their ancient knowledge would once again be required.
The alleged associations and origins of crystal skull mythology in Native American spiritual lore, as advanced by neoshamanic writers such as Jamie Sams, are similarly discounted. Instead, as Philip Jenkins notes, crystal skull mythology may be traced back to the "baroque legends" initially spread by F. A. Mitchell-Hedges, and then afterwards taken up:
"By the 1970's, the crystal skulls had entered
New Age mythology as potent relics of ancient
Atlantis, and they even acquired a canonical
number: there were exactly thirteen skulls."
None of this would have anything to do with North American Indian matters, if the skulls had not attracted the attention of some of the most active New Age writers.
Boeing B-29 Superfortress “FIFI”, serial number 44-62070 Profile
FiFi, a B-29 bomber, and one of the more notable planes, participated in a special event at the New Century Air Center in Gardner, Kansas. The event was called the Air Power History Tour, where three working World War II airplanes were on display until Sunday. The event took place August 20 through August 24 at the New Century AirCenter in Gardner Kansas. This picture taken Sunday, August 24th.
This particular aircraft was delivered to the U.S. Army Air Corps in Salina, Kansas, on July 31, 1945. It remained state-side for its entire career, assigned to several airbases including Strategic Air Command, Grand Island Field, Nebraska. It was converted to a TB-29 trainer in 1953 and transferred to the U.S. Navy in 1956 and eventually ended up at China Lake, California.
The B-29 was designed as a long-range heavy bomber, and whose nickname “Superfortress” is derived from the B-17 “Flying Fortress” nickname coined by Richard L. Williams, a writer and editor for the Seattle Times, when he was assigned to write a caption on a photo of the Model 299, a prototype of the B-17 that was unveiled at Boeing on July 17, 1935. Boeing presented a prototype as early as 1939, but the production version did not see combat until 1944. B-29s were flown in the Pacific Theater during World War II, where their long range and large bomb load were most needed (although two were delivered for non-combat to Europe late in the war – my dad was there in 1946 and spoke of them). The B-29 is, of course, most known for having dropped the atomic bombs on Hiroshima and Nagasaki (a secondary target chosen due to poor visibility over the primary target of Kokura). After its establishment in 1946, the U.S. Strategic Air Command began deployment of B-29s, some as RB-29 reconnaissance aircraft.
Powered by four Wright R-3350-23 Duplex/Cyclone engines, the B-29 was the first bomber to have pressurized crew compartments: forward, aft, and tail gunner positions, with a pressurized connecting tunnel over the bomb bays. It was entirely innovative in its use of an analog computerized remote-controlled sighting system for the guns. Except for the tail gunner, the gunners no longer sat in turrets but rather in sighting stations using a remote periscope sighting system for the turrets which had switches to obtain or relinquish control of the four turrets; the top turret gunner/central fire control officer had switches for changing control as to which gunner was on the target depending on his field of view; the gunners communicated via the interphone system.
The bombardier was generally responsible for the forward dorsal 4-gun turret and the forward ventral 2-gun turret for frontal attacks. Armament in this aircraft includes: twin-mounted General Electric .50 caliber machine guns in remote-controlled forward and rear ventral turrets and a ventral rear aft turret, and quad-mounted .50 cal. in a remote-controlled forward dorsal turret, and a pair in the tail turret. (Armament varied in these aircraft and a 20 mm cannon was added to the tail turret on some aircraft).
The crew generally consisted of ten: pilot, co-pilot, bombardier/togglier, flight engineer, radio operator, navigator, right gunner, left gunner, top gunner or central fire control, tail gunner (11 when radar was used). The top gunner sat in a pedestal seat nicknamed the “Barber’s Seat.” Due to the complexity of this aircraft, the flight engineer (who sat behind the co-pilot, facing aft and looking at an array of controls) had a very active role in flying the aircraft, responsible for the minute-by-minute monitoring and control of the engines. Each crew position was fitted with a 1936 Ford ashtray. The aircraft had a forward and smaller aft bomb bay and could carry a range of ordnance.
