Aérospatiale-BAC Concorde /ˈkɒŋkɔrd/ is a retired turbojet-powered supersonic passenger airliner or supersonic transport (SST). It is one of only two SSTs to have entered commercial service; the other was the Tupolev Tu-144. Concorde was jointly developed and produced by Aérospatiale and the British Aircraft Corporation (BAC) under an Anglo-French treaty. First flown in 1969, Concorde entered service in 1976 and continued commercial flights for 27 years.
Among other destinations, Concorde flew regular transatlantic flights from London Heathrow and Paris-Charles de Gaulle Airport to New York JFK, Washington Dulles and Barbados; it flew these routes in less than half the time of other airliners. With only 20 aircraft built, the development of Concorde was a substantial economic loss; Air France and British Airways also received considerable government subsidies to purchase them. Concorde was retired in 2003 due to a general downturn in the aviation industry after the type's only crash in 2000, the 9/11 terrorist attacks in 2001, and a decision by Airbus, the successor firm of Aérospatiale and BAC, to discontinue maintenance support.
A total of 20 aircraft were built in France and the United Kingdom; six of these were prototypes and development aircraft. Seven each were delivered to Air France and British Airways. Concorde's name reflects the development agreement between the United Kingdom and France. In the UK, any or all of the type—unusually for an aircraft—are known simply as "Concorde", without an article. The aircraft is regarded by many people as an aviation icon and an engineering marvel.
Early studies
Concorde
The origins of the Concorde project date to the early 1950s, when Arnold Hall, director of the Royal Aircraft Establishment (RAE) asked Morien Morgan to form a committee to study the SST concept. The group met for the first time in February 1954 and delivered their first report in April 1955.
At the time it was known that the drag at supersonic speeds was strongly related to the span of the wing. This led to the use of very short-span, very thin rectangular wings like those seen on the control surfaces of many missiles, or in aircraft like the Lockheed F-104 Starfighter or the Avro 730 that the team studied. The team outlined a baseline configuration that looked like an enlarged Avro 730, or more interestingly, almost exactly like the Lockheed CL-400 "Suntan" proposal.
This same short span produced very little lift at low speed, which resulted in extremely long takeoff runs and frighteningly high landing speeds. In an SST design, this would have required enormous engine power to lift off from existing runways, and to provide the fuel needed, "some horribly large aeroplanes" resulted. Based on this, the group considered the concept of an SST unfeasible, and instead suggested continued low-level studies into supersonic aerodynamics.
Slender deltas
Soon after, Dietrich Küchemann at the RAE published a series of reports on a new wing planform, known in the UK as the "slender delta" concept. Küchemann's team, including Eric Maskell and Johanna Weber, worked with the fact that delta wings can produce strong vortexes on their upper surfaces at high angles of attack. The vortex will lower the air pressure and cause lift to be greatly increased. This effect had been noticed earlier, notably by Chuck Yeager in the Convair XF-92, but its qualities had not been fully appreciated. Küchemann suggested that this was no mere curiosity, and the effect could be deliberately used to improve low speed performance.
Küchemann's papers changed the entire nature of supersonic design almost overnight. Although the delta had already been used on aircraft prior to this point, these designs used planforms that were not much different from a swept wing of the same span. Küchemann noted that the lift from the vortex was increased by the length of the wing it had to operate over, which suggested that the effect would be maximized by extending the wing along the fuselage as far as possible. Such a layout would still have good supersonic performance inherent to the short span, while also offering reasonable takeoff and landing speeds using vortex generation. The only downside to such a design is that the aircraft would have to take off and land very "nose high" in order to generate the required vortex lift, which led to questions about the low speed handling qualities of such a design. It would also need to have long landing gear to produce the required angles while still on the runway.
Küchemann presented the idea at a meeting where Morgan was also present. Eric Brown recalls Morgan's reaction to the presentation, saying that he immediately seized on it as the solution to the SST problem. Brown considers this moment as being the true birth of the Concorde project.
Design
Concorde is an ogival (also "ogee") delta-winged aircraft with four Olympus engines based on those employed in the RAF's Avro Vulcan strategic bomber. Concorde was the first airliner to have a (in this case, analogue) fly-by-wire flight-control system; the avionics of Concorde were unique because it was the first commercial aircraft to employ hybrid circuits. The principal designer for the project was Pierre Satre, with Sir Archibald Russell as his deputy.
Concorde pioneered the following technologies:
For high speed and optimisation of flight:
Double delta (ogee/ogival) shaped wings
Variable engine air intake system controlled by digital computers
Supercruise capability
Thrust-by-wire engines, predecessor of today’s FADEC-controlled engines
Droop-nose section for better landing visibility
For weight-saving and enhanced performance:
Mach 2.04 (~2,179 km/h or 1,354 mph) cruising speed for optimum fuel consumption (supersonic drag minimum although turbojet engines are more efficient at higher speed) Fuel consumption at Mach 2.0 and altitude of 60,000 feet was 4,800 gallons per hour.
Mainly aluminium construction for low weight and conventional manufacture (higher speeds would have ruled out aluminium)
Full-regime autopilot and autothrottle allowing "hands off" control of the aircraft from climb out to landing
Fully electrically controlled analogue fly-by-wire flight controls systems
High-pressure hydraulic system of 28 MPa (4,000 lbf/in²) for lighter hydraulic components
Complex Air Data Computer (ADC) for the automated monitoring and transmission of aerodynamic measurements (total pressure, static pressure, angle of attack, side-slip).
Fully electrically controlled analogue brake-by-wire system
Pitch trim by shifting fuel around the fuselage for centre-of-gravity control
Parts made using "sculpture milling", reducing the part count while saving weight and adding strength.
No auxiliary power unit, as Concorde would only visit large airports where ground air start carts are available.
Engines
Concorde's intake system
Concorde needed to fly long distances to be economically viable; this required high efficiency. Turbofan engines were rejected due to their larger cross-section producing excessive drag. Turbojets were found to be the best choice of engines. The engine used was the twin spool Rolls-Royce/Snecma Olympus 593, a development of the Bristol engine first used for the Avro Vulcan bomber, and developed into an afterburning supersonic variant for the BAC TSR-2 strike bomber. Rolls-Royce's own engine proposed for the aircraft at the time of Concorde's initial design was the RB.169.
The aircraft used reheat (afterburners) at takeoff and to pass through the upper transonic regime and to supersonic speeds, between Mach 0.95 and Mach 1.7. The afterburners were switched off at all other times. Due to jet engines being highly inefficient at low speeds, Concorde burned two tonnes of fuel (almost 2% of the maximum fuel load) taxiing to the runway. Fuel used is Jet A-1. Due to the high power produced even with the engines at idle, only the two outer engines were run after landing for easier taxiing.
The intake design for Concorde’s engines was especially critical.[Conventional jet engines can take in air at only around Mach 0.5; therefore the air has to be slowed from the Mach 2.0 airspeed that enters the engine intake. In particular, Concorde needed to control the shock waves that this reduction in speed generates to avoid damage to the engines. This was done by a pair of intake ramps and an auxiliary spill door, whose position moved in-flight to slow transiting air.
Engine failure causes problems on conventional subsonic aircraft; not only does the aircraft lose thrust on that side but the engine creates drag, causing the aircraft to yaw and bank in the direction of the failed engine. If this had happened to Concorde at supersonic speeds, it theoretically could have caused a catastrophic failure of the airframe. Although computer simulations predicted considerable problems, in practice Concorde could shut down both engines on the same side of the aircraft at Mach 2 without the predicted difficulties. During an engine failure the required air intake is virtually zero so, on Concorde, engine failure was countered by the opening of the auxiliary spill door and the full extension of the ramps, which deflected the air downwards past the engine, gaining lift and minimising drag. Concorde pilots were routinely trained to handle double engine failure.
Heating issues
Air compression on the outer surfaces caused the cabin to heat up during flight. Every surface, such as windows and panels, was warm to the touch by end of the flight. Besides engines, the hottest part of the structure of any supersonic aircraft, due to aerodynamic heating, is the nose. The engineers used Hiduminium R.R. 58, an aluminium alloy, throughout the aircraft due to its familiarity, cost and ease of construction. The highest temperature that aluminium could sustain over the life of the aircraft was 127 °C (261 °F), which limited the top speed to Mach 2.02. Concorde went through two cycles of heating and cooling during a flight, first cooling down as it gained altitude, then heating up after going supersonic. The reverse happened when descending and slowing down. This had to be factored into the metallurgical and fatigue modelling. A test rig was built that repeatedly heated up a full-size section of the wing, and then cooled it, and periodically samples of metal were taken for testing. The Concorde airframe was designed for a life of 45,000 flying hours.
Owing to air friction as the plane travelled at supersonic speed, the fuselage would heat up and expand by as much as 300 mm (almost 1 ft). The most obvious manifestation of this was a gap that opened up on the flight deck between the flight engineer's console and the bulkhead. On some aircraft that conducted a retiring supersonic flight, the flight engineers placed their caps in this expanded gap, wedging the cap when it shrank again. To keep the cabin cool, Concorde used the fuel as a heat sink for the heat from the air conditioning. The same method also cooled the hydraulics. During supersonic flight the surfaces forward from the cockpit became heated, and a visor was used to deflect much of this heat from directly reaching the cockpit.
Concorde had livery restrictions; the majority of the surface had to be covered with a highly reflective white paint to avoid overheating the aluminium structure due to heating effects from supersonic flight at Mach 2. The white finish reduced the skin temperature by 6 to 11 degrees Celsius. In 1996, Air France briefly painted F-BTSD in a predominantly blue livery, with the exception of the wings, in a promotional deal with Pepsi. In this paint scheme, Air France were advised to remain at Mach 2 for no more than 20 minutes at a time, but there was no restriction at speeds under Mach 1.7. F-BTSD was used because it was not scheduled for any long flights that required extended Mach 2 operations.
Structural issues
Fuel pitch trim
Due to the high speeds at which Concorde travelled, large forces were applied to the aircraft's structure during banks and turns. This caused twisting and the distortion of the aircraft’s structure. In addition there were concerns over maintaining precise control at supersonic speeds; both of these issues were resolved by active ratio changes between the inboard and outboard elevons, varying at differing speeds including supersonic. Only the innermost elevons, which are attached to the stiffest area of the wings, were active at high speed. Additionally, the narrow fuselage meant that the aircraft flexed. This was visible from the rear passengers’ viewpoints.
When any aircraft passes the critical mach of that particular airframe, the centre of pressure shifts rearwards. This causes a pitch down force on the aircraft if the centre of mass remains where it was. The engineers designed the wings in a specific manner to reduce this shift, but there was still a shift of about 2 metres. This could have been countered by the use of trim controls, but at such high speeds this would have caused a dramatic increase in the drag on the aircraft. Instead, the distribution of fuel along the aircraft was shifted during acceleration and deceleration to move the centre of mass, effectively acting as an auxiliary trim control.
Range
In order to fly non-stop across the Atlantic Ocean, Concorde was developed to have the greatest supersonic range of any aircraft. This was achieved by a combination of engines which were highly efficient at supersonic speeds, a slender fuselage with high fineness ratio, and a complex wing shape for a high lift to drag ratio. This also required carrying only a modest payload and a high fuel capacity, and the aircraft was trimmed with precision to avoid unnecessary drag.
Nevertheless, soon after Concorde began flying, a Concorde "B" model was designed with slightly larger fuel capacity and slightly larger wings with leading edge slats to improve aerodynamic performance at all speeds, with the objective of expanding the range to reach markets in new regions. It featured more powerful engines with sound deadening and without the fuel-hungry and noisy reheat. It was speculated that it was reasonably possible to create an engine with up to 25% gain in efficiency over the Rolls-Royce/Snecma Olympus 593. This would have given 500 mi (805 km) additional range and a greater payload, making new commercial routes possible. This was cancelled due in part to poor sales of Concorde, but also to the rising cost of aviation fuel in the 1970s.
Droop Nose
Concorde’s drooping nose, developed by Marshall Aerospace, enabled the aircraft to switch between being streamlined to reduce drag and achieve optimum aerodynamic efficiency, and not obstructing the pilot's view during taxi, takeoff, and landing operations. Due to the high angle of attack the long pointed nose obstructed the view and necessitated the capability to droop. The droop nose was accompanied by a moving visor that retracted into the nose prior to being lowered. When the nose was raised to horizontal, the visor would rise in front of the cockpit windscreen for aerodynamic streamlining.
A controller in the cockpit allowed the visor to be retracted and the nose to be lowered to 5° below the standard horizontal position for taxiing and takeoff. Following takeoff and after clearing the airport, the nose and visor were raised. Prior to landing, the visor was again retracted and the nose lowered to 12.5° below horizontal for maximum visibility. Upon landing the nose was raised to the five-degree position to avoid the possibility of damage.
The Federal Aviation Administration had objected to the restrictive visibility of the visor used on the first two prototype Concordes and thus requiring alteration before the FAA would permit Concorde to serve US airports; this led to the redesigned visor used on the production and the four pre-production aircraft. The nose window and visor glass needed to endure temperatures in excess of 100 °C (212 °F) at supersonic flight were developed by Triplex.
Retirement
Concorde's final flight; G-BOAF from Heathrow to Bristol, on 26 November 2003. The extremely high fineness ratio of the fuselage is evident.
On 10 April 2003, Air France and British Airways simultaneously announced that they would retire Concorde later that year. They cited low passenger numbers following the 25 July 2000 crash, the slump in air travel following the September 11, 2001 attacks, and rising maintenance costs. Although Concorde was technologically advanced when introduced in the 1970s, 30 years later, its analogue cockpit was dated. There had been little commercial pressure to upgrade Concorde due to a lack of competing aircraft, unlike other airliners of the same era such as the Boeing 747. By its retirement, it was the last aircraft in British Airways' fleet that had a flight engineer; other aircraft, such as the modernised 747-400, had eliminated the role.
On 11 April 2003, Virgin Atlantic founder Sir Richard Branson announced that the company was interested in purchasing British Airways’ Concorde fleet for their nominal original price of £1 (US$1.57 in April 2003) each. British Airways dismissed the idea, prompting Virgin to increase their offer to £1 million each. Branson claimed that when BA was privatised, a clause in the agreement required them to allow another British airline to operate Concorde if BA ceased to do so, but the Government denied the existence of such a clause. In October 2003, Branson wrote in The Economist that his final offer was "over £5 million" and that he had intended to operate the fleet "for many years to come". The chances for keeping Concorde in service were stifled by Airbus's lack of support for continued maintenance.
It has been suggested that Concorde was not withdrawn for the reasons usually given but that it became apparent during the grounding of Concorde that the airlines could make more profit carrying first class passengers subsonically. A lack of commitment to Concorde from Director of Engineering Alan MacDonald was cited as having undermined BA’s resolve to continue operating Concorde.
Air France
Air France made its final commercial Concorde landing in the United States in New York City from Paris on 30 May 2003. Air France's final Concorde flight took place on 27 June 2003 when F-BVFC retired to Toulouse.
An auction of Concorde parts and memorabilia for Air France was held at Christie's in Paris on 15 November 2003; 1,300 people attended, and several lots exceeded their predicted values. French Concorde F-BVFC was retired to Toulouse and kept functional for a short time after the end of service, in case taxi runs were required in support of the French judicial enquiry into the 2000 crash. The aircraft is now fully retired and no longer functional.
French Concorde F-BTSD has been retired to the "Musée de l'Air et de l'Espace" at Le Bourget (near Paris) and, unlike the other museum Concordes, a few of the systems are being kept functional. For instance, the famous "droop nose" can still be lowered and raised. This led to rumours that they could be prepared for future flights for special occasions.
French Concorde F-BVFB currently rests at the Auto & Technik Museum Sinsheim at Sinsheim, Germany, after its last flight from Paris to Baden-Baden, followed by a spectacular transport to Sinsheim via barge and road. The museum also has a Tu-144 on display – this is the only place where both supersonic airliners can be seen together.
British Airways[edit]

British Airways conducted a North American farewell tour in October 2003. G-BOAG visited Toronto Pearson International Airport on 1 October, after which it flew to New York’s John F. Kennedy International Airport. G-BOAD visited Boston’s Logan International Airport on 8 October, and G-BOAG visited Washington Dulles International Airport on 14 October. It has been claimed that G-BOAD’s flight from London Heathrow to Boston set a transatlantic flight record of 3 hours, 5 minutes, 34 seconds. However the fastest transatlantic flight was from New York JFK airport to Heathrow on 7 February 1996, taking 2 hours, 52 minutes, 59 seconds; 90 seconds less than a record set in April 1990.
In a week of farewell flights around the United Kingdom, Concorde visited Birmingham on 20 October, Belfast on 21 October, Manchester on 22 October, Cardiff on 23 October, and Edinburgh on 24 October. Each day the aircraft made a return flight out and back into Heathrow to the cities, often overflying them at low altitude. On 22 October, both Concorde flight BA9021C, a special from Manchester, and BA002 from New York landed simultaneously on both of Heathrow's runways. On 23 October 2003, the Queen consented to the illumination of Windsor Castle, an honour reserved for state events and visiting dignitaries, as Concorde's last west-bound commercial flight departed London.
British Airways retired its Concorde fleet on 24 October 2003. G-BOAG left New York to a fanfare similar to that given for Air France’s F-BTSD, while two more made round trips, G-BOAF over the Bay of Biscay, carrying VIP guests including former Concorde pilots, and G-BOAE to Edinburgh. The three aircraft then circled over London, having received special permission to fly at low altitude, before landing in sequence at Heathrow. The captain of the New York to London flight was Mike Bannister. The final flight of a Concorde in the US occurred on 5 November 2003 when G-BOAG flew from New York's Kennedy Airport to Seattle's Boeing Field to join the Museum of Flight's permanent collection. The plane was piloted by Mike Bannister and Les Broadie who claimed a flight time of three hours, 55 minutes and 12 seconds, a record between the two cities. The museum had been pursuing a Concorde for their collection since 1984. The final flight of a Concorde world-wide took place on 26 November 2003 with a landing at Filton, Bristol, UK.
All of BA's Concorde fleet have been grounded, drained of hydraulic fluid and their airworthiness certificates withdrawn. Jock Lowe, ex-chief Concorde pilot and manager of the fleet estimated in 2004 that it would cost £10–15 million to make G-BOAF airworthy again. BA maintain ownership and have stated that they will not fly again due to a lack of support from Airbus. On 1 December 2003, Bonhams held an auction of British Airways’ Concorde artifacts, including a nose cone, at Kensington Olympia in London. Proceeds of around £750,000 were raised, with the majority going to charity. G-BOAD is currently on display at the Intrepid Sea, Air & Space Museum in New York. In 2007, BA announced that the advertising spot at Heathrow where a 40% scale model of Concorde was located would not be retained; the model is now on display at the Brooklands Museum.
Chrysler Concorde (1998)
The Concorde was completely redesigned for the 1998 model year. The new design was similar to the new Chrysler LHS, however the two models each had a unique front end shape and different rear fascias. The "Second Generation" design was introduced in 1996 as the Chrysler LHX Concept Car. This concept vehicle had large 20" wheels, and a centrally located instrument cluster. The wheelbase was expanded to 124 inches (3,100 mm) to allow for rear passenger supplement restraints, rear occupant entertainment center and storage compartment.
Despite overall length increasing by 7.5 inches (190 mm), the second generation's weight dropped by nearly a hundred pounds. This was achieved by extensive use of aluminum for the rear suspension, hood, as well as the two new engines. In addition the 214 hp (160 kW) 3.5-liter V6 engine, there was also a new 200 hp (149 kW) 2.7-liter V6 and 225 hp (168 kW) 3.2-liter V6. The 3.5-liter was redone and output upgraded to 253 hp (189 kW) and was available on the 2002-2004 Concorde Limited (formerly LHS).
Much was done in the design process to make the second generation LH sedans look more distinct from each other. The 1998 Concorde differed far greater from the Dodge Intrepid and the new 1999 Chrysler 300M (successor to the Eagle Vision), than did the first generation models. With the exception of the doors and roof, the Concorde shared little sheetmetal with the Intrepid and 300M. The new Concorde's front end was underscored by a striking full-width grille, relocated to the front bumper to give the impression of a bottom breather. Sweeping curves and a more rounded front end also helped set the Concorde apart from the Intrepid and 300M. The second generation Chrysler LHS had an appearance very similar to the Concorde; The only major differences being its more centrally located single frame grille and amber turn signals on the taillights.
As in the previous generation, six passenger seating with a front bench seat and column shifter was optional. Cloth seating was standard on base LX with leather seating optional. Leather was standard on upscale LXi and later Limited models.
The Concorde, 300M, and Intrepid were discontinued in 2004. The all-new Chrysler 300 replaced the Concorde (and 300M) in late 2004 as a 2005 model.
The Concorde 2nd generation replaced the first generation car (launched in 1991), itself derived from the AMC division Eagle Premier (and Dodge Monaco). Interestingly, these two AMC products were directly related to the then-new Renault 25 and inherited the Renault north-south installation of the powertrains, with the engine mounted ahead of, and driving, the front axle. This layout is very similar to that used in the larger Audis, thus permitting the installation of a all-wheel-drive system for added traction, though there were no volume models of either the AMC division cars, or the latter LHS platform Chryslers that used this system.

Model of a mining excavator in front shovel configuration in scale 1:28.5. This 300 tonne machine is a representative of Liebherr's most popular size class and is ideally suited to load a fleet of 100 tonne payload mining trucks.
When LEGO introduced its 42100 Liebherr R 9800, I knew I had to get that set immediately after release. But I also knew from the beginning, that I would not like the official model's Technic design and that I had to build my own version.
Here it is, scaled larger than 42100, but on the other hand representing a much smaller machine than the 9800. About 300 vs. 800 tonnes in real life. This allowed me to use the main components of the official LEGO model to build my R 994 B. I used the clamshell bucket, the Power Functions XL actuators and the tracks and sprockets.
The main difference from 42100 lies in the electric components of my model. The following functions are all powered by two Power Functions rechargeable battery boxes and controlled by three SBricks via bluetooth connection and Brick Controller 2 app:
- Left and right crawler treads each using a Power Functions L motor
- Slewing of the upper structure using two Power Functions M motors
- Boom cylinders: one Power Functions XL motor
- Stick cylinders: one Power Functions L motor
- Bucket cylinders: one Power Functions M motor
- Clamshell bucket: one Brick Engine V1 motor (compatible to Power Functions)
- Access ladder: one Power Functions M motor
- Service flap: one Power Functions M motor
- Lighting: three pairs of Power Functions LEDs
Besides the main drive and digging functions, the model features a retractable access ladder and a lowerable service flap on the underside of the upper structure frame. The service flap is used to refuel and grease the excavator.
While building the Liebherr R 994 B Litronic in 1:28.5 scale, I could refer to a highly detailed diecast model of the very same machine in 1:50 scale.

The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries during and after the Second World War. The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft. It was also the only British fighter to be in continuous production throughout the war. The Spitfire continues to be a popular aircraft, with approximately 55 Spitfires being airworthy, while many more are static exhibits in aviation museums all over the world.
The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (which operated as a subsidiary of Vickers-Armstrong from 1928). In accordance with its role as an interceptor, Mitchell designed the Spitfire's distinctive elliptical wing to have the thinnest possible cross-section; this thin wing enabled the Spitfire to have a higher top speed than several contemporary fighters, including the Hawker Hurricane. Mitchell continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the development of the Spitfire through its multitude of variants.
During the Battle of Britain (July–October 1940), the Spitfire was perceived by the public to be the RAF fighter, though the more numerous Hawker Hurricane shouldered a greater proportion of the burden against the Luftwaffe. However, because of its higher performance, Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes.
After the Battle of Britain, the Spitfire superseded the Hurricane to become the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber and trainer, and it continued to serve in these roles until the 1950s. The Seafire was a carrier-based adaptation of the Spitfire which served in the Fleet Air Arm from 1942 through to the mid-1950s. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030 hp (768 kW), it was strong enough and adaptable enough to use increasingly powerful Merlin and, in later marks, Rolls-Royce Griffon engines producing up to 2,340 hp (1,745 kW); as a consequence of this the Spitfire's performance and capabilities improved, sometimes dramatically, over the course of its life.
Mk V (Types 331, 349 & 352)
Spitfire LF.Mk VB, BL479, flown by Group Captain M.W.S Robinson, station commander of RAF Northolt, August 1943. This Spitfire has the wide bladed Rotol propeller, the internal armoured windscreen and "clipped" wings.
Late in 1940, the RAF predicted that the advent of the pressurised Junkers Ju 86P bomber series over Britain would be the start of a new sustained high altitude bombing offensive by the Luftwaffe, in which case development was put in hand for a pressurised version of the Spitfire, with a new version of the Merlin (the Mk VI). It would take some time to develop the new fighter and an emergency stop-gap measure was needed as soon as possible: this was the Mk V.
The basic Mk V was a Mk I with the Merlin 45 series engine. This engine delivered 1,440 hp (1,074 kW) at take-off, and incorporated a new single-speed single-stage supercharger design. Improvements to the carburettor also allowed the Spitfire to use zero gravity manoeuvres without any problems with fuel flow. Several Mk I and Mk II airframes were converted to Mk V standard by Supermarine and started equipping fighter units from early 1941. The majority of the Mk Vs were built at Castle Bromwich.
The VB became the main production version of the Mark Vs. Along with the new Merlin 45 series the B wing was fitted as standard. As production progressed changes were incorporated, some of which became standard on all later Spitfires. Production started with several Mk IBs which were converted to Mk VBs by Supermarine. Starting in early 1941 the round section exhaust stacks were changed to a "fishtail" type, marginally increasing exhaust thrust. Some late production VBs and VCs were fitted with six shorter exhaust stacks per side, similar to those of Spitfire IXs and Seafire IIIs; this was originally stipulated as applying specifically to VB(trop)s. After some initial problems with the original Mk I size oil coolers, a bigger oil cooler was fitted under the port wing; this could be recognised by a deeper housing with a circular entry. From mid-1941 alloy covered ailerons became a universal fitting.
Spitfire VC(trop), fitted with Vokes filters and "disc" wheels, of 417 Squadron RCAF in Tunisia in 1943.
A constant flow of modifications were made as production progressed. A "blown" cockpit hood, manufactured by Malcolm, was introduced in an effort to further increase the pilot's head-room and visibility. Many mid to late production VBs - and all VCs - used the modified, improved windscreen assembly with the integral bullet resistant centre panel and flat side screens introduced with the Mk III. Because the rear frame of this windscreen was taller than that of the earlier model the cockpit hoods were not interchangeable and could be distinguished by the wider rear framing on the hood used with the late-style windscreen.
Different propeller types were fitted, according to where the Spitfire V was built: Supermarine and Westland manufactured VBs and VCs used 10 ft 9 in (3.28 m) diameter, 3 bladed de Havilland constant speed units, with narrow metal blades, while Castle Bromwich manufactured VBs and VCs were fitted with a wide bladed Rotol constant speed propeller of either 10 ft 9 in (3.28 m) diameter, with metal blades, or (on late production Spitfires) 10 ft 3 in (3.12 m) diameter, with broader, "Jablo" (compressed wood) blades. The Rotol spinners were longer and more pointed than the de Havilland leading to a 3.5 in (8.9 cm) increase in overall length. The Rotol propellers allowed a modest speed increase over 20,000 ft (6,100 m) and an increase in the service ceiling. A large number of Spitfire VBs were fitted with "gun heater intensifier" systems on the exhaust stacks. These piped additional heated air into the gun bays. There was a short tubular intake on the front of the first stack and a narrow pipe led into the engine cowling from the rear exhaust.
The VB series were the first Spitfires able to carry a range of specially designed "slipper" drop tanks which were fitted underneath the wing centre-section. Small hooks were fitted, just forward of the inboard flaps: when the tank was released these hooks caught the trailing edge of the tank, swinging it clear of the fuselage.
With the advent of the superb Focke Wulf Fw 190 in August 1941 the Spitfire was for the first time truly outclassed, hastening the development of the "interim" Mk IX. In an effort to counter this threat, especially at lower altitudes, the VB was the first production version of the Spitfire to use "clipped" wingtips as an option, reducing the wingspan to 32 ft 2 in (9.8 m).The clipped wings increased the roll rate and airspeed at lower altitudes. Several different versions of the Merlin 45/50 family were used, including the Merlin 45M which had a smaller "cropped" supercharger impeller and boost increased to +18 lb. This engine produced 1,585 hp (1,182 kW) at 2,750 ft (838 m), increasing the L.F VB's maximum rate of climb to 4720 ft/min (21.6 m/s) at 2,000 ft (610 m).
VB Trop of 40 Squadron SAAF fitted with the "streamlined" version of the Aboukir filter, a broad-bladed, 10 ft 3 in (3.12 m) diameter Rotol propeller, and clipped wings.
The Mk VB(trop) (or type 352) could be identified by the large Vokes air filter fitted under the nose; the reduced speed of the air to the supercharger had a detrimental effect on the performance of the aircraft, reducing the top speed by 8 mph (13 km/h) and the climb rate by 600 ft/min (3.04 m/s), but the decreased performance was considered acceptable. This variant was also fitted with a larger oil tank and desert survival gear behind the pilot's seat. A new "desert" camouflage scheme was applied. Many VB(trop)s were modified by 103 MU (Maintenance Unit-RAF depots in which factory fresh aircraft were brought up to service standards before being delivered to squadrons) at Aboukir, Egypt by replacing the Vokes filter with locally manufactured "Aboukir" filters, which were lighter and more streamlined. Two designs of these filters can be identified in photos: one had a bulky, squared off filter housing while the other was more streamlined. These aircraft were usually fitted with the wide blade Rotol propeller and clipped wings.
Triumph Spitfire Mk I Roadster
The Triumph Spitfire is a small English two-seat sports car, introduced at the London Motor Show in 1962.[3] The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The platform for the car was largely based upon the chassis, engine, and running gear of the Triumph Herald saloon, and was manufactured at the Standard-Triumph works at Canley, in Coventry. As was typical for cars of this era, the bodywork was fitted onto a separate structural chassis, but for the Spitfire, which was designed as an open top or convertible sports car from the outset, the ladder chassis was reinforced for additional rigidity by the use of structural components within the bodywork. The Spitfire was provided with a manual hood for weather protection, the design improving to a folding hood for later models. Factory-manufactured hard-tops were also available.
The Triumph Spitfire was originally devised by Standard-Triumph to compete in the small sports car market that had opened up with the introduction of the Austin-Healey Sprite. The Sprite had used the basic drive train of the Austin A30/35 in a light body to make up a budget sports car; Triumph's idea was to use the mechanicals from their small saloon, the Herald, to underpin the new project. Triumph had one advantage, however; where the Austin A30 range was of unitary construction, the Herald featured a separate chassis. It was Triumph's intention to cut that chassis down and clothe it in a sports body, saving the costs of developing a completely new chassis / body unit.
Italian designer Michelotti—who had already penned the Herald—was commissioned for the new project, and came up with a traditional, swooping body. Wind-up windows were provided (in contrast to the Sprite/Midget, which still featured sidescreens, also called curtains, at that time), as well as a single-piece front end which tilted forwards to offer unrivaled access to the engine. At the dawn of the 1960s, however, Standard-Triumph was in deep financial trouble, and unable to put the new car into production; it was not until the company was taken over by the Leyland organization funds became available and the car was launched. Leyland officials, taking stock of their new acquisition, found Michelotti's prototype hiding under a dust sheet in a corner of the factory and rapidly approved it for production.
Spitfire 4 or Mark I (1962-1964)
Overview:
Production1962–1964

Powertrain:
Engine1,147 cc (1.1 l) I4
Transmission4-speed manual with optional overdrive on top and third from 1963 onwards
Dimensions:
Curb weight1,568 lb (711 kg) (unladen U.K.-spec)
The production car changed little from the prototype, although the full-width rear bumper was dropped in favour of two part-bumpers curving round each corner, with overriders. Mechanicals were basically stock Herald. The engine was an 1,147 cc (1.1 l) 4-cylinder with a pushrod OHV cylinder head and 2 valves per cylinder, mildly tuned for the Spitfire, fed by twin SU carburettors. Also from the Herald came the rack and pinion steering and coil-and-wishbone front suspension up front, and at the rear a single transverse-leaf swing axle arrangement. This ended up being the most controversial part of the car: it was known to "tuck in" and cause violent over steer if pushed too hard, even in the staid Herald. In the sportier Spitfire (and later the 6-cylinder Triumph GT6 and Triumph Vitesse) it led to severe criticism. The body was bolted to a much-modified Herald chassis, the outer rails and the rear outriggers having been removed; little of the original Herald chassis design was left, and the Spitfire used structural outer sills to stiffen its body tub.
The Spitfire was an inexpensive small sports car and as such had very basic trim, including rubber mats and a large plastic steering wheel. These early cars were referred to both as "Triumph Spitfire Mark I" and "Spitfire 4", not to be confused with the later Spitfire Mark IV.
In UK specification the in-line four produced 63 bhp (47 kW) at 5750 rpm, and 67 lb·ft (91 N·m)of torque at 3500 rpm. This gave a top speed of 92 mph (148 km/h), and would achieve 0 to 60 mph (97 km/h) in 17.3 seconds. Average fuel consumption was 31mpg.
For 1964 an overdrive option was added to the 4-speed manual gearbox to give more relaxed cruising. Wire wheels and a hard top were also available.

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!
After the Saab 38 (also known as B3LA) had been cancelled in 1979 in favor of the more advanced Saab JAS 39 Gripen multi-role fighter, Saab presented in 1991 a new trainer design to the Swedish Air Force as a replacement for the Saab 105 (Sk 60) transitional trainer, light attack and reconnaissance aircraft. This new aircraft was internally called "FSK900". The aircraft was a conservative design, with such a configurational resemblance to the Dassault-Dornier Alpha Jet that it is hard to believe Saab engineers didn't see the Alpha Jet as a model for what they wanted to do. However, even if that was the case, the FSK900 was by no means a copy of the Alpha Jet, and the two machines could be easily told apart at a glance. FSK900 had a muscular, rather massive appearance, while the Alpha Jet was more wasp-like and very sleek. The FSK900 was also bigger in length and span and had an empty weight about 10% greater.
The FSK900 was mostly made of aircraft aluminum alloys, with some control surfaces made of carbon-fiber / epoxy composite, plus very selective use of titanium. It had high-mounted swept wings, with a supercritical airfoil section and a leading-edge dogtooth; a conventional swept tail assembly; tricycle landing gear; twin engines, one mounted in a pod along each side of the fuselage; and a tandem-seat cockpit with dual controls.
The wings had a sweep of 27.5°, an anhedral droop of 7°, and featured ailerons for roll control as well as double slotted flaps. The tailplanes were all-moving, and also featured an anhedral of 7°. An airbrake was mounted on each side of the rear fuselage. Flight controls were hydraulic, and hydraulic systems were dual redundant.
Instructor and cadet sat in tandem in a common cockpit, both on zero-zero ejection seats, with the instructor's seat in the rear raised 27 centimeters (10.6 inches) to give a good forward view. The cockpit was pressurized and featured a one-piece canopy, hinged open to the right, which provided excellent visibility.
The landing gear assemblies all featured single wheels, with the nose gear retracting forward and the main gear retracting forward and into the fuselage, featuring an antiskid braking system. The twin engines were two Williams International FJ44-4M turbofans without reheat, each rated at 16.89 kN (3,790 lbst). These were the same engines that Saab had also proposed for Saab’s Sk 60 modernization program, even though a less powerful variant for the lighter aircraft.
The FSK900 could be fitted with two pylons under each wing and under the fuselage centerline, for a total of five hardpoints and a total external payload of 2,500 kg (5,500 lb). The inner wing pylons were wet and could take 450 liter (119 US gallon) auxiliary tanks. External stores included a centerline target winch for the target tug role, an air-sampling pod for detection of fallout or other atmospheric pollutants, jammer or chaff pods for electronic warfare training, a camera/sensor pod and a baggage pod for use in the liaison role. The aircraft also featured a baggage compartment in the center fuselage, which also offered space for other special equipment or future updates.
Potential armament comprised a conformal ventral pod with a single 27 mm Mauser BK-27 revolver cannon with 120 rounds (the same weapon that eventually went into the Saab Gripen). Other weapons included various iron and cluster bombs of up to 454 kg (1.000 lb) caliber, unguided missiles of various calibers and the Rb.74 (AIM-9L Sidewinder) AAM. A radar was not mounted, but the FSK900’s nose section offered enough space for a radome.
The Swedish Air Force accepted the Saab design, leading to a contract for two nonflying static-test airframes and four flying prototypes. Detail design was complete by the end of 1993 and prototype construction began in the spring of 1994, leading to first flight of the initial prototype on 29 July 1994. The first production "Sk 90A", how the basic trainer type was officially dubbed, was delivered to the Swedish Air Force in 1996.
A total of 108 production Sk 90s were built until 1999 in several versions. The initial Sk 90A trainer was the basis for the Sk 90B variant, which carried a weather radar (this variant was not adopted by the Swedish air force but sold to Austria) and the C variant with a set of cameras in the nose for the Swedish air force. In service, the type was regarded as strong, agile, and pleasant to fly, while being cheap to operate. Swedish Sk 90As flying in the training role were typically painted in the unique “Fields & Meadows” splinter camouflage, although decorative paint jobs showed up on occasion and many aircraft received additional dayglow markings. Some of the few aircraft given to operational squadrons, which used them for keeping up flight hours and as hacks, had been painted in an all-grey camouflage to match the combat aircraft they shared the flight line with.
Despite its qualities and potential, the Sk 90 did not attain much foreign interest, primarily suffering from bad timing and from the focus on domestic demands. The aircraft came effectively 10 years too late to become a serious export success, and in the end the Sk 90 was very similar to the Dassault/Dornier Alpha Jet (even though it was cheaper to operate) - at a time when the German Luftwaffe started to prematurely phase out its attack variant and flooded the global´market with cheap second hand aircraft in excellent condition. Furthermore, the Saab Sk 90 had, with the BAe Hawk, another proven competitor with a long operational track record all over the world.
Potential buyers were Malaysia as well as Singapore, Myanmar, Finland, Poland and Hungary. Austria eventually procured 36 Sk 90 Ö in 2002, replacing its Saab 105 fleet and keeping up its close connection with Saab since the Seventies, and a late customer became the independent Republic of Scotland in 2017, initially with a dozen leased Saab Sk 90A trainers.
This procurement was preceded by a White Paper published by the Scottish National Party (SNP) in 2013, which stated that an independent Scotland would have an air force equipped with up to 16 air defense aircraft, six tactical transports, utility rotorcraft and maritime patrol aircraft, and be capable of “contributing excellent conventional capabilities” to NATO. Outlining its ambition to establish an air force with an eventual 2,000 uniformed personnel and 300 reservists, the SNP stated the organization would initially be equipped with “a minimum of 12 interceptors in the Eurofighter/Typhoon class, based at Lossiemouth, a tactical air transport squadron, including around six Lockheed Martin C-130J Hercules, and a helicopter squadron”.
According to the document, “Key elements of air forces in place at independence, equipped initially from a negotiated share of current UK assets, will secure core tasks, principally the ability to police Scotland’s airspace, within NATO.” An in-country air command and control capability would be established within five years of a decision in favor of independence, it continues, with staff also to be “embedded within NATO structures”.
This plan was immediately set into action after the country's independence from Great Britain in late 2017 with the purchase of twelve refurbished Saab JAS 39A Gripen interceptors for Quick Reaction Alert duties and former Swedish Air Force Sk 90A trainers for the nascent Republic of Scotland Air Corps (RoScAC), locally called Saab Sk90A “Iolaire” (Eaglet) T.1. These machines either came from operational Swedish squadrons or were put back into operation from mothballed overstock.
All machines were delivered to Scotland in the Swedish all-grey paint scheme, the machines taken from operational service had their original Swedish markings just painted over. The were all exclusively allocated to the newly established Eaglais a' Bhaile Ùir Flying Training School at Kirknewtoun (a former RAF air base) near Edinburgh. In 2019, the RoScAC’s first brand new aircraft arrived in the form of TF-50 “Golden Eagle” fighters from South Korea, which, as multi-role two seaters, complemented the Saab Sk 90’s in the advanced trainer role and also took over air space patrol duties from the Scottish JAS 39.
In early 2020, the leasing contract for the Sk 90s with Sweden was changed into a formal purchase, and the Iolaire fleet (as well as the Gripen fighters) gradually received the RoScAC’s new camouflage scheme in grey and green, which had been introduced with the TF-50s.

The kit and its assembly:
This whif is a rarity among my builds, since it is an alternative reality model. A fictional air force of an independent Scotland crept into my mind after the hysterical “Brexit” events in 2016 and the former (failed) public vote concerning the independence of Scotland from the UK. However, the situation bore some serious storytelling potential: What would happen to the military if the independence would have actually taken place and British forces had left the country?
The aforementioned Scottish National Party (SNP) paper from 2013 is actually real, and I took it as a guideline. Primary focus would certainly be set on air space defense, and the Gripen appeared as a good and not too expensive choice. An advanced trainer would also have been needed, and the Sk 90 (a personal invention and already built as a Swedish and Austrian aircraft) would fulfill a complementary role.
A Scottish Sk 90 had been on my agenda since 2016, and now materialized as an addition to my Scottish TF-50 and two Sk 90s (a swedish and an Austrian one). The Saab Sk 90 is basically the 1:72 Kawasaki T-4 from Hasegawa, and since it was to depict an original Sk 90A, formerly operated by Sweden, it was built without modifications. The kit is relatively simple and fit is quite good, even though some PSR was necessary on almost any seam – there are actually two T-4 molds, and this one is the more recent offering.
Painting and markings:
I wanted to depict a RoScAC aircraft of the first hour, so I went for a Swedish look with tactical markings from the new operator. Since I already had a Sk 90 in Swedish “Fields & Meadows” camouflage, I decided to go for a Gripen-esque grey-in-grey livery.
Swedish JAS 39 carry a two-tone livery; the upper tone is called pansargrå (tank grey, which is, according to trustworthy sources, very close to FS 36173, Neutral Grey), while the undersides are painted in duvagrå (dove grey, FS 36373, a tone with the confusing name ”High Low Visibility Light Grey”), and the simple pattern was faithfully adapted to the T-4.
After checking a lot of Gripen pictures I selected different tones, though, because the colors appear much lighter in real life. I ended up with FS 36231 (Dark Gull Grey, Testors 1740) and RLM 63 (Lichtgrau, Testors 2077) – in combination, these tones come IMHO quite close to the real thing?
After a light black ink wash I emphasized single panels with Humbrol 165 and 147. The cockpit interior was painted with Revell 47 (Mausgrau) while the landing gear became glossy white.
For the RoScAC look I added some manually overpainted patches where the former Swedish roundels and tactical markings would have been. As a trainer, I also added orange dayglow markings on the fin and the wings, created with generic decal sheet material (TL Modellbau). The de-icing devices on the wings’ and fin’s leading edges were created with black decal stripes instead of paint, a very tidy and simple method. Decal strips in silver were used on the fin’s rudder and on the flaps. Small things, but they grade the grey model up visually.
Another creative field were the national markings: how could fictional Scottish roundels look like, and how to create them so that they are easy to make and replicate (for a full set for this kit, as well as for potential future builds…)? Designing and printing marking decals myself was an option, but I eventually settled for a composite solution which somewhat influenced the roundels’ design, too.
My Scottish roundel interpretation, already used on my RoScAC T-50, consists of a simple blue disk with a white cross – a straightforward solution since it’s different from any other contemporary national marking, esp. the UK roundel, and easy to create from single decal parts. In fact, the roundel discs were die-punched from blue decal sheet, and the cross consists of two thin white decal strips, cut into the correct length with the same stencil, again using generic sheet material from TL Modellbau.
Another issue was the potential tactical code, and a small fleet only needs a simple system. Going back to a WWII system with letter codes for squadrons and individual aircraft was one option, but, IMHO, still too complicated. However, for individual aircraft identification I adopted the familiar British single letter aircraft code, and since the RoScAC would certainly not operate too many squadrons, I rather adapted a system similar to the Swedish or Spanish format with a single number representing the squadron – or, in this case a letter, because the fictional Flying Training School would not be a front line unit.
The result is a simple 2-digit code, and I adapted the German system of placing the tactical code on the fuselage, separated by the roundel. Keeping British traditions up I repeated the individual aircraft code letter on the fin, where I also placed a Scottish flag (scratched from the same decal material as the roundels. A small serial number, created from single black letters (once more Tl Modellbau material) was added on the rear fuselage, and, for some local pride, I added a self-printed coat-of-arms of Edinburgh to the air intakes.
Finally, after some light weathering, the kit was finally sealed with matt acrylic varnish (Italeri).
Creating this whif, based on an alternative historic timeline and with a near future perspective, was fun – and it might spawn more models that circle around this story. A certain future build is a Saab Gripen in RoScAC colors and there might also be an entry level trainer (Shorts Tucano?), some helicopters for the army or SAR duties and maybe a transport aircraft, but not a big one. The foundation has been laid out, now it’s time to fill Scotland’s alternative recent history with detail and hardware proof. ;-)

The wings had a sweep of 27.5°, an anhedral droop of 7°, and featured ailerons for roll control as well as double slotted flaps. The tailplanes were all-moving, and also featured an anhedral of 7°. An airbrake was mounted on each side of the rear fuselage. Flight controls were hydraulic, and hydraulic systems were dual redundant.
Instructor and cadet sat in tandem in a common cockpit, both on zero-zero ejection seats, with the instructor's seat in the rear raised 27 centimeters (10.6 inches) to give a good forward view. The cockpit was pressurized and featured a one-piece canopy, hinged open to the right, which provided excellent visibility.
The landing gear assemblies all featured single wheels, with the nose gear retracting forward and the main gear retracting forward and into the fuselage, featuring an antiskid braking system. The twin engines were two Williams International FJ44-4M turbofans without reheat, each rated at 16.89 kN (3,790 lbst). These were the same engines that Saab had also proposed for Saab’s Sk 60 modernization program, even though a less powerful variant for the lighter aircraft.
The FSK900 could be fitted with two pylons under each wing and under the fuselage centerline, for a total of five hardpoints and a total external payload of 2,500 kg (5,500 lb). The inner wing pylons were wet and could take 450 liter (119 US gallon) auxiliary tanks. External stores included a centerline target winch for the target tug role, an air-sampling pod for detection of fallout or other atmospheric pollutants, jammer or chaff pods for electronic warfare training, a camera/sensor pod and a baggage pod for use in the liaison role. The aircraft also featured a baggage compartment in the center fuselage, which also offered space for other special equipment or future updates.
Potential armament comprised a conformal ventral pod with a single 27 mm Mauser BK-27 revolver cannon with 120 rounds (the same weapon that eventually went into the Saab Gripen). Other weapons included various iron and cluster bombs of up to 454 kg (1.000 lb) caliber, unguided missiles of various calibers and the Rb.74 (AIM-9L Sidewinder) AAM. A radar was not mounted, but the FSK900’s nose section offered enough space for a radome.
The Swedish Air Force accepted the Saab design, leading to a contract for two nonflying static-test airframes and four flying prototypes. Detail design was complete by the end of 1993 and prototype construction began in the spring of 1994, leading to first flight of the initial prototype on 29 July 1994. The first production "Sk 90A", how the basic trainer type was officially dubbed, was delivered to the Swedish Air Force in 1996.
A total of 108 production Sk 90s were built until 1999 in several versions. The initial Sk 90A trainer was the basis for the Sk 90B variant, which carried a weather radar (this variant was not adopted by the Swedish air force but sold to Austria) and the C variant with a set of cameras in the nose for the Swedish air force. In service, the type was regarded as strong, agile, and pleasant to fly, while being cheap to operate. Swedish Sk 90As flying in the training role were typically painted in the unique “Fields & Meadows” splinter camouflage, although decorative paint jobs showed up on occasion and many aircraft received additional dayglow markings. Some of the few aircraft given to operational squadrons, which used them for keeping up flight hours and as hacks, had been painted in an all-grey camouflage to match the combat aircraft they shared the flight line with.
Despite its qualities and potential, the Sk 90 did not attain much foreign interest, primarily suffering from bad timing and from the focus on domestic demands. The aircraft came effectively 10 years too late to become a serious export success, and in the end the Sk 90 was very similar to the Dassault/Dornier Alpha Jet (even though it was cheaper to operate) - at a time when the German Luftwaffe started to prematurely phase out its attack variant and flooded the global´market with cheap second hand aircraft in excellent condition. Furthermore, the Saab Sk 90 had, with the BAe Hawk, another proven competitor with a long operational track record all over the world.
Potential buyers were Malaysia as well as Singapore, Myanmar, Finland, Poland and Hungary. Austria eventually procured 36 Sk 90 Ö in 2002, replacing its Saab 105 fleet and keeping up its close connection with Saab since the Seventies, and a late customer became the independent Republic of Scotland in 2017, initially with a dozen leased Saab Sk 90A trainers.
This procurement was preceded by a White Paper published by the Scottish National Party (SNP) in 2013, which stated that an independent Scotland would have an air force equipped with up to 16 air defense aircraft, six tactical transports, utility rotorcraft and maritime patrol aircraft, and be capable of “contributing excellent conventional capabilities” to NATO. Outlining its ambition to establish an air force with an eventual 2,000 uniformed personnel and 300 reservists, the SNP stated the organization would initially be equipped with “a minimum of 12 interceptors in the Eurofighter/Typhoon class, based at Lossiemouth, a tactical air transport squadron, including around six Lockheed Martin C-130J Hercules, and a helicopter squadron”.
According to the document, “Key elements of air forces in place at independence, equipped initially from a negotiated share of current UK assets, will secure core tasks, principally the ability to police Scotland’s airspace, within NATO.” An in-country air command and control capability would be established within five years of a decision in favor of independence, it continues, with staff also to be “embedded within NATO structures”.
This plan was immediately set into action after the country's independence from Great Britain in late 2017 with the purchase of twelve refurbished Saab JAS 39A Gripen interceptors for Quick Reaction Alert duties and former Swedish Air Force Sk 90A trainers for the nascent Republic of Scotland Air Corps (RoScAC), locally called Saab Sk90A “Iolaire” (Eaglet) T.1. These machines either came from operational Swedish squadrons or were put back into operation from mothballed overstock.
All machines were delivered to Scotland in the Swedish all-grey paint scheme, the machines taken from operational service had their original Swedish markings just painted over. The were all exclusively allocated to the newly established Eaglais a' Bhaile Ùir Flying Training School at Kirknewtoun (a former RAF air base) near Edinburgh. In 2019, the RoScAC’s first brand new aircraft arrived in the form of TF-50 “Golden Eagle” fighters from South Korea, which, as multi-role two seaters, complemented the Saab Sk 90’s in the advanced trainer role and also took over air space patrol duties from the Scottish JAS 39.
In early 2020, the leasing contract for the Sk 90s with Sweden was changed into a formal purchase, and the Iolaire fleet (as well as the Gripen fighters) gradually received the RoScAC’s new camouflage scheme in grey and green, which had been introduced with the TF-50s.

The kit and its assembly:
This whif is a rarity among my builds, since it is an alternative reality model. A fictional air force of an independent Scotland crept into my mind after the hysterical “Brexit” events in 2016 and the former (failed) public vote concerning the independence of Scotland from the UK. However, the situation bore some serious storytelling potential: What would happen to the military if the independence would have actually taken place and British forces had left the country?
The aforementioned Scottish National Party (SNP) paper from 2013 is actually real, and I took it as a guideline. Primary focus would certainly be set on air space defense, and the Gripen appeared as a good and not too expensive choice. An advanced trainer would also have been needed, and the Sk 90 (a personal invention and already built as a Swedish and Austrian aircraft) would fulfill a complementary role.
A Scottish Sk 90 had been on my agenda since 2016, and now materialized as an addition to my Scottish TF-50 and two Sk 90s (a swedish and an Austrian one). The Saab Sk 90 is basically the 1:72 Kawasaki T-4 from Hasegawa, and since it was to depict an original Sk 90A, formerly operated by Sweden, it was built without modifications. The kit is relatively simple and fit is quite good, even though some PSR was necessary on almost any seam – there are actually two T-4 molds, and this one is the more recent offering.
Painting and markings:
I wanted to depict a RoScAC aircraft of the first hour, so I went for a Swedish look with tactical markings from the new operator. Since I already had a Sk 90 in Swedish “Fields & Meadows” camouflage, I decided to go for a Gripen-esque grey-in-grey livery.
Swedish JAS 39 carry a two-tone livery; the upper tone is called pansargrå (tank grey, which is, according to trustworthy sources, very close to FS 36173, Neutral Grey), while the undersides are painted in duvagrå (dove grey, FS 36373, a tone with the confusing name ”High Low Visibility Light Grey”), and the simple pattern was faithfully adapted to the T-4.
After checking a lot of Gripen pictures I selected different tones, though, because the colors appear much lighter in real life. I ended up with FS 36231 (Dark Gull Grey, Testors 1740) and RLM 63 (Lichtgrau, Testors 2077) – in combination, these tones come IMHO quite close to the real thing?
After a light black ink wash I emphasized single panels with Humbrol 165 and 147. The cockpit interior was painted with Revell 47 (Mausgrau) while the landing gear became glossy white.
For the RoScAC look I added some manually overpainted patches where the former Swedish roundels and tactical markings would have been. As a trainer, I also added orange dayglow markings on the fin and the wings, created with generic decal sheet material (TL Modellbau). The de-icing devices on the wings’ and fin’s leading edges were created with black decal stripes instead of paint, a very tidy and simple method. Decal strips in silver were used on the fin’s rudder and on the flaps. Small things, but they grade the grey model up visually.
Another creative field were the national markings: how could fictional Scottish roundels look like, and how to create them so that they are easy to make and replicate (for a full set for this kit, as well as for potential future builds…)? Designing and printing marking decals myself was an option, but I eventually settled for a composite solution which somewhat influenced the roundels’ design, too.
My Scottish roundel interpretation, already used on my RoScAC T-50, consists of a simple blue disk with a white cross – a straightforward solution since it’s different from any other contemporary national marking, esp. the UK roundel, and easy to create from single decal parts. In fact, the roundel discs were die-punched from blue decal sheet, and the cross consists of two thin white decal strips, cut into the correct length with the same stencil, again using generic sheet material from TL Modellbau.
Another issue was the potential tactical code, and a small fleet only needs a simple system. Going back to a WWII system with letter codes for squadrons and individual aircraft was one option, but, IMHO, still too complicated. However, for individual aircraft identification I adopted the familiar British single letter aircraft code, and since the RoScAC would certainly not operate too many squadrons, I rather adapted a system similar to the Swedish or Spanish format with a single number representing the squadron – or, in this case a letter, because the fictional Flying Training School would not be a front line unit.
The result is a simple 2-digit code, and I adapted the German system of placing the tactical code on the fuselage, separated by the roundel. Keeping British traditions up I repeated the individual aircraft code letter on the fin, where I also placed a Scottish flag (scratched from the same decal material as the roundels. A small serial number, created from single black letters (once more Tl Modellbau material) was added on the rear fuselage, and, for some local pride, I added a self-printed coat-of-arms of Edinburgh to the air intakes.
Finally, after some light weathering, the kit was finally sealed with matt acrylic varnish (Italeri).
Creating this whif, based on an alternative historic timeline and with a near future perspective, was fun – and it might spawn more models that circle around this story. A certain future build is a Saab Gripen in RoScAC colors and there might also be an entry level trainer (Shorts Tucano?), some helicopters for the army or SAR duties and maybe a transport aircraft, but not a big one. The foundation has been laid out, now it’s time to fill Scotland’s alternative recent history with detail and hardware proof. ;-)

Some background:
The Arsenal (de l'Aéronautique) VB 31 was a French naval fighter aircraft developed shortly after World War II. In January 1947 Arsenal were given a contract to develop a powerful naval fighter for the four French aircraft carriers. Since the modernization of the Aéronavale was pressing, the aircraft had to be developed fast. In order to cut time, the initial concept, the VB 30, was based on the unrealized German Messerschmitt Me 155 project.
The Me 155 naval fighter had been a naval development of the Messerschmitt Bf 109G, intended for the German aircraft carrier Graf Zeppelin, which never saw the light of day. When it was clear that the Me 155 was a dead end, the basic design was developed further into a high altitude interceptor and the project handed over to Blohm & Voss. The resulting, highly modified Bv 155 saw the prototype stage in the late years of WWII, but was never put into service. Years later, though, the Me 155 should surface again: Evolved by Ingenieur-General Vernisse and M. Badie, the VB 30 did not only use many design features of the original Me 155 design, it also heavily drew on the indigenous VB 10 heavy fighter which had been previously under development since WWII.
The VB 30 was more compact than the VB 10, though, even though it had similar proportions. IIt was an all-metal single-seat fighter with a low-wing monoplane, a retractable tailwheel undercarriage and of largely orthodox configuration. The wings had an inverted gull wing shape, in order to shorten the main undercarriage as much as possible, and were foldable. The landing gear retracted inwards, and the tail wheel was retractable, too.
The VB 30's layout resembled much the smaller North American Mustang. The aircraft was powered by a powerful Arsenal 24 H engine which was theoretically capable of 3.400hp – itself a development based on the cylinder blocks of the German Junkers IV12 213 engine. A huge radiator bath for the liquid-cooled engine was located under the fuselage, at the wings’ trailing edge.
The aircraft was heavily armed, with a newly developed, compact 30mm cannon (which would eventually become the famous DEFA cannon), firing through the propeller axis, plus four HS-404 20mm cannons or six 12.7mm machine guns in the wings, outside of the propeller arc. Various ordnance loads, including bombs of up to 500 kg caliber, drop tanks or unguided missiles, could be carried under the fuselage and outer wings.
Unlike the huge, tandem-engined VB 10, the VB 30 was (relatively) more successful, but its career started under misfortunate stars: Just one month after the VB 10 contract was cancelled, the prototype VB 30-01 made its maiden flight on 8th of December 1948. Overall, the aircraft behaved well, but its low speed handling was hampered by the immense torque of the Arsenal 24 H engine and the huge, four-bladed propeller. This problem was eventually countered with an enlarged fin, which earned the type its nickname "Requin" (Shark).
With this and many other detail modifications the aircraft was now called VB 31and cleared for series production, even though it was already apparent that the future of the fighter lay with jet power. A second prototype, the VB 30-02, had been started, but its assembly lagged so much behind that it was eventually finished as the first serial VB 31. Anyway, the development of the VB 31 continued as a safety net for France's nascent jet fighter programs, since it was not clear when pure jets would eventually offer the appropriate performance for carrier use, and when they'd be ready for service.
The VB 31’s development saw several drawbacks, including constant problems with the complicated, liquid-cooled engine, the radiator system and the landing gear. Serial production and service introduction of the VB 31 started slowly and was delayed until January 1951 – by which the French Air Force already had to rely on surplus British and American fighters to tide it over until domestically-produced jet fighters appeared. Time was already working against the VB 31.
Additionally, with the brooding Indochina War since August 1945, the need for a maritime fighter and fighter-bomber became so dire that the Aéronavale had to order the WWII Vought F4U-7 to fill this specific gap and replace several obsolete types. The XF4U-7 prototype did its test flight on 2 July 1952 with a total of 94 F4U-7s built for the French Navy's Aéronavale (79 in 1952, 15 in 1953), with the last of the batch, the final Corsair built, rolled out on 31 January 1953. With this proven (and cheaper) alternative, only a single batch of 40 VB 31 aircraft (instead of the planned 200!) was eventually built and put into service.
The VB 31 just came in time for the First Indochina War between France’s French Far East Expeditionary Corps and Emperor Báo Dai’s Vietnamese National Army against the Viet Minh, Led by Ho Chi Minh and Vo Nguyen Giap. During this conflict, the French used many different pre Cold War aircraft of World War Two, as well as the new types.The VB 31 were distrubuted between Flotille 3F and 12F, where they replayced Curtiss SB2C Helldivers and Grumman F6F-3 Hellcats, respectively. Flotille 12F pilots arrived in Asia on board of the aircraft carrier 'Arromanches' in early 1952, equipped with both VB 31 and F4U-7 fighters. Both types were deployed from the carrier and also served from Haiphong for CAS and escort duties in the Tonkin area.
The operational era of the VB 31 did not last long, though. The type was powerful, but complicated. The VB 31 also needed much more maintenance than the sturdy Corsair, which could also take more damage and had a considerable larger range. Hence, already in June 1953, all VB 31 were returned to Europe and based at Hyères, where they replaced obsolete F6F-5 Hellcats and were mainly used for training purposes. In the early sixties, with naval jet fighters finally available, the VB 31 were quickly withdrawn and scrapped, being replaced by Sud-Ouest SO-203 'Aquilon' (license-built D.H. Sea Venom) and Dassault Etendard IVM.

The Kit and its assembly:
I wonder if you recognize the basis for this fantasy airplane? It's actually a modified Bv 155 kit from ART Model/Special Hobby from Russia (Both kits are identical; the ART Model contains an injected clear canopy while the Special Hobby kit offers two vacu canopies, though).
Inspiration struck when I read about the huge VB 10, which has, in its profile view, much resemblance to the Bv 155 - and the latter actually has some naval-friendly features, e .g .the raised cockpit, placed pretty far forward at the wings' leading edge, or the massive landing gear. Since France used some German aircraft after WWII (e.g. Fw 190 for the Air Force and Ju 188 for the Navy), why not create a naval fighter from the Me 155/Bv 155 concept? Well, here it is... the Arsenal VB 31.
For this fantasy conversion, the Bv 155 kit saw major modifications, e. g.:
● The wing span was reduced - from each wing, 4.2cm/1.65" were taken away
● The wings received a new inverted gull wing shape, the cuts came handy
● Outer wings were clipped by 10mm/0,4" each
● Original wing tips were transplanted and re-sculpted to fit
● The rear fuselage was shortened by about 1.3cm/0.5"
● A carburetor intake was added under the nose (from a Hawker Hurricane)
● New horizontal stabilizers from a Grumman Panther (Matchbox)
● Lower position of the horizontal stabilizers
● New landing gear wells had to be cut out, a simple interior was scratch-built
● The landing gear retracts now inwards, original struts and covers were slightly shortened
● New main wheels from a Douglas Skyknight (Matchbox) were used
● New tail wheel (front wheel of a Revell F-16, I guess)
● Modified tail section with an arrestor hook
● The original, extensive exhaust piping between the engine and the turbo charger had to go
● New exhausts at the nose were added (scratch, HO scale roof tiles)
● New propeller from a Matchbox Hawker Tempest was mated with the original spinner
● Cockpit was taken OOB, but a different seat, a pilot and a radio in the rear were added
● Some panel lines had to be re-engraved, due to putty work and/or logical reasons
● Missile hardpoints under the wings come from an F4U
● Antennae were added, accoring to French F4U-7 pictures
There actually was no big plan - I had an idea of what to make from the kit, but modifications came step by step, as the parts fell together and looked or looked not right.
The 24 cylinder Arsenal 24 H engine was really under development in France, so it was a neat choice for such a relatively large aircraft. The huge turbocharger bath under the fuselage of the Bv 155 could easily be taken as a radiator bath for the large, liquid-cooled engine, so that no additional adaptations had to be made.
Overall, I wanted to save the elegant lines of the Bv 155. With the reduced wing span the aircraft looks even elegant, IMHO. All in all, and with its slender, inverted gull wings, the VB 31 somehow reminds of the Ju 87 and the later paper Ju 187 development. There's also something IL-2ish to it?
A side note concerning the kit itself: it has nice engraved details and some fine resin parts for the cockpit or the radiators. But wall strength is high (up to 2mm!), the material is somewhat soft and waxy, and fit is mediocre, so expect serious putty work. Not a bad kit, but something for the experienced modeler. Things surely were worse here, since my modifications to wings and fuselage called for even more sculpting.
Painting and markings:
It took some time to settle on a French naval aircraft, since I already have an all dark-blue whif in my collection (the whiffy F1J Sea Mustang). But I had some appropriate decals at hand, and the time frame as well as the potential user offered a good and plausible story behind the VB 31 in Aéronaval service.
Overall, the aircraft was painted in Blue Angels Blue (FS 15050, Testors 1718) and weathered with slightly lighter shades of blue and grey, for a sun-bleached look and in order to emphasize the panel lines. One can argue about this tone: many Aéronavale aircraft look much darker, rather like FS 15042, but I have seen pictures of such bright aircraft - I'd assume that the color standard was not very strict, as long as the aircraft was "dark blue"?
After basic painting the VB 31 looked very bright, so I did some major dry painting with darker/duller shades like Humbrol 67, 77 and 104 to tame things down, and the result is O.K. now.
The interior surfaces were painted in Mid Stone and dry-painted with Chromate Yellow (Humbrol 225 and 81). AFAIK, this is the typical interior finish for Aéronavel aircraft of that time, and it is a nice contrast to the dark and uniform outside.
Most markings come from an F4U-7 decal sheet, some things like the tail rudder Tricolore had to be improvised (comes from a 30 year old Airfix Bristol Blenheim decal sheet!).
Beyond the dry-painted blue and grey hues on the upper surfaces, the model was slightly weathered with exhaust and soot stains and some dry-painted silver on the leading edges. This makes the all-blue aircraft look a bit more lively and is IMHO authentic for Aéronavale fighters of the 50ies, esp. under the harsh climate of South East Asia.
Finally, everything was sealed under a semi-matt varnish (Tamiya Acryllics, rattle can), and some additional matt varnish was applied on the upper surfaces, also for a dull and sun-bleached look.
The kit was built in a week from sprues to pictures, overall a sleek and elegant aircraft with plausible lines - an hommage to the many elegant and innovative aircraft which were developed in France in WWII and later but which are easily overlooked today!
Two Northern Counties bodied Olympians, one of the Volvo variety, the other of the Leyland type, sit at First's Rainham depot.
The Leyland machine, H144 FLX, was new to London Buslines as fleet number 44, and later became 124 in the fleet of Capital, later First Capital. Today, in its dotage, it remains active and allocated to Bridport, part of First's Hants & Dorset operation.
As for S210 LLO, it ended up converted to single-door configuration and working for First in South Yorkshire.
My new North American diesel engine in the Canadian Nation Railway scheme is the first Lego loco I have built since my childhood days and was strongly inspired by the EMD-GP 7, 9 and 20 diesel engines and other similar types that came in full high hood configuration, but I went on to building the model rather freely, leaving out things I didn’t want and not sticking to any particular real model.
Being 9+ studs wide, it’s quite a beast and fits very well to the “large city minifigure scale” preferred by ER0L and me. It drives on two 9V train motors from the 90s. The lighting is realized with materials from that time as well, energized by a separate battery box in the shorter section of the hood and thus illuminating the two fronts and cabin of the engine independently from the transformer. That way, the light can be on even when the model stands still.
I went for moving pilots, even though they don’t exist on such models in reality. This was mostly due to the prolonged bionicle trucks I wanted to use here, which would otherwise have made the stairs stand out too far from the trucks in curves and switches.
I have nearly finished building the first of several tank cars for it, so consider these pics an “opener” for more train equipment to come from me.

Some background:
In September 1952, the United States Navy announced a requirement for a new fighter. It was to have a top speed of Mach 1.2 at 30,000 ft (9,144.0 m) with a climb rate of 25,000 ft/min (127.0 m/s), and a landing speed of no more than 100 mph (160 km/h). Korean War experience had demonstrated that 0.50 inch (12.7 mm) machine guns were no longer sufficient, and as the result the new fighter was to carry a 20 mm (0.79 in) cannon. In response, the Vought team led by John Russell Clark, created the V-383. Unusual for a fighter, the aircraft had a high-mounted wing which necessitated the use of a fuselage-mounted short and light landing gear.
The Crusader was powered by a Pratt and Whitney J57 turbojet engine. The engine was equipped with an afterburner that, unlike on later engines, was either fully lit, or off (i.e. it did not have "zones"). The engine produced 18,000 lb of thrust at full power, enough to allow the F-8 to climb straight up in clean configuration. The most innovative aspect of the design was the variable-incidence wing which pivoted by 5° out of the fuselage on takeoff and landing (not to be confused with variable-sweep wing). This allowed a greater angle of attack, increasing lift without compromising forward visibility. This innovation helped the F-8's development team win the Collier Trophy in 1956. Simultaneously, the lift was augmented by leading-edge slats drooping by 25° and inboard flaps extending to 30°. The rest of the aircraft took advantage of contemporary aerodynamic innovations with area-ruled fuselage, all-moving stabilators, dog-tooth notching at the wing folds for improved yaw stability, and liberal use of titanium in the airframe.
The armament, as specified by the Navy, consisted primarily of four 20 mm (.79 in) autocannons, and the Crusader happened to be the last U.S. fighter designed with guns as its primary weapon. They were supplemented with a retractable tray with 32 unguided Mk 4/Mk 40 Folding-Fin Aerial Rocket (Mighty Mouse FFARs), and cheek pylons for a pair of IR-guided AIM-9 Sidewinder air-to-air missiles. In practice, AIM-9 Sidewinder missiles were the F-8's primary weapon, because the 20mm guns were "generally unreliable."
In May 1953, the Vought design was declared a winner and in June, Vought received an order for three XF8U-1 prototypes (after adoption of the unified designation system in September 1962, the F8U became the F-8). The first prototype flew on 25 March 1955 with John Konrad at the controls, exceeding the speed of sound during its maiden flight. On 4 April 1956, the F8U-1 performed its first catapult launch from Forrestal.
In US service, the F-8 served principally in the Vietnam War and several versions, including all-weather fighters with improved radar and photo-recce versions, were developed. An update program between 1965 and 1970 prolonged the fighters’ time of active duty into the late Seventies. The RF-8 reconnaissance aircraft served longer and were retired in 1987.
Despite its qualities, only a few foreign countries operated the F-8. Beyond France and the Philippines, Argentina bought twelve revamped Crusaders plus two additional airframes for spares from US surplus stock for its carrier ARA Veinticinco de Mayo (V-2) in 1975. The ship previously served in the Royal Navy as HMS Venerable and the Royal Netherlands Navy as HNLMS Karel Doorman and had been put into Argentine service in 1969. It could carry up to 24 aircraft and initially operated with obsolete F4U Corsairs and F9F Panthers and Cougars. These were soon replaced by A-4Q Skyhawks (modified A-4Bs, also from US stock), but these machines were rather fighter bombers than interceptors that could not effectively guard the ship or its surrounding fleet from air strikes. This led to the procurement of Argentina’s small F-8 fleet, a process that started in 1973, just after the Skyhawks had entered service.
The Argentinian Crusaders (locally known as “Cruzados”) were based on the F-8E all-weather fighter variant. This type was the ultimate evolution of the original F-8 series, before the modernization program that turned these machines into F-8Js in US service. The F-8E was, beyond its four 20mm cannon, able to carry up to four AIM-9 Sidewinder AAMs on Y-shaped fuselage pylons. The original unguided missile pannier had been replaced by an extra fuel tank, and two dry underwing pylons allowed the carriage of unguided bombs or missiles. The USN’s F-8Es also had extra avionics in a shallow dorsal hump for the deployment of the radio-guided AGM-12 Bullpup air-to-ground missile, so that the aircraft could also carry out strike duties against small target – in theory, since the AGM-12 had to be visually guided by the pilot all the way while flying at lower levels in the combat environment.
However, the Argentine Navy requested some peculiar modifications for its aircraft, which were quite similar to the French Navy’s F-8E (FN), the last Crusaders that had left the production lines in 1965. This special Crusader variant became the F-8Q. It retained the F-8E’s J57-P-20A engine as well as the AN/APQ-94 fire-control radar and the IRST sensor blister in front of the canopy. A Martin-Baker ejection seat was fitted and the cockpit instruments were updated to Argentinian standards.
In order to ease operation and especially landing on the relatively small Veinticinco de Mayo, the F-8Q was, like the French Crusaders, modified with the maximum angle of incidence of the aircraft's wing increased from five to seven degrees, and blown flaps were fitted, too. This reduced the rate of descent to 11’ (3.35 m) per second and limited the force of gravity during landings to 3.5 G. The approach speed was also considerably reduced, by roundabout 15 knots (17.5 mph or 28 km/h).
Since Argentina did not operate the AGM-12 Bullpup and wanted a dedicated interceptor, the missile avionics were deleted and the hump disappeared, in an effort to save weight. Furthermore, the wing pylons received plumbing so that drop tanks could be carried, beyond the standard unguided ordnance of bombs or unguided missile pods. The F-8Q’s total payload was 5,000 lb (2,270 kg), but when operating from Veinticinco de Mayo, any external ordnance beyond the four Sidewinders was ever carried because the F-8’s TOW was at the ship’s catapult limits. When operating from land bases, the F-8Qs would frequently carry drop tanks in order to extend their range.
Upon delivery in late 1975, the F-8Q’s sported the standard US Navy scheme of Light Gull Grey upper surfaces over white undersides, just like the Skyhawks and other operational aircraft types of the Argentinian Navy. Typically, six F-8Qs were always based on board of Veinticinco de Mayo and rotated with the rest of the machines, which were, together with A-4Qs, based at BAN Rio Grande.
The F-8Qs formed the 1st Flight of the 3 Escuadrilla Aeronaval de Caza y Ataque that operated from Veinticinco de Mayo, and the machines received tactical codes between “101” and “112”. However, this gave in 1980 way to a more toned-down paint scheme in dark blue-grey over white, at a phase when Argentina tried to acquire Dassault Super Étendards and Exocet missiles from France. The new paint scheme was gradually introduced, though, the first to be re-painted were “107”, “108” and “110” in summer 1981.
Despite their availability, the F-8Qs did not actively take part in the Falklands War of 1982. This was primarily because ARA Veinticinco de Mayo was initially used in support of the Argentine landings on the Falklands: on the day of the invasion, she waited with 1.500 army soldiers outside Stanley harbor as first submarine and boat-landed commandos secured landing areas, and then Argentine marines made the main amphibious landing. Her aircraft were not used during the invasion and remained at land bases.
Later, in defense of the occupation, the carrier was deployed in a task force north of the Falkland Islands, with ARA General Belgrano to the south, and this time the usual six F-8Qs were on board and provided air cover. Out of fear from losing the carrier, though (the British had assigned HMS Splendid (S106), a nuclear-powered submarine, to track down Veinticinco de Mayo and sink her if necessary), the ship and its aircraft remained mostly outside of the direct confrontation theatre and rather acted as a distraction, binding British resources and attention.
However, after hostilities broke out on 1 May 1982, the Argentine carrier attempted to launch a wave of A-4Q Skyhawk jets against the Royal Navy Task Force after her S-2 Trackers detected the British fleet. What would have been the first battle between aircraft carriers since World War II did not take place, though, as winds prevented the heavily loaded jets from being launched. After the British nuclear-powered submarine HMS Conqueror sank General Belgrano, Veinticinco de Mayo returned to port for her own safety. The naval A-4Q Skyhawks flew the rest of the war from the airbase in Río Grande, Tierra del Fuego, and had some success against the Royal Navy, sinking HMS Ardent, even though three Skyhawks were shot down by Sea Harriers. The Crusaders were held back for homeland defense from Río Gallegos air base, since Argentina’s limited air refueling capacities (just a pair of C-130s, and all buddy refueling packs for the Skyhawks were out of order) had to be saved and concentrated on the Skyhawks.
After her involvement in the Falklands/Malvinas conflict, Veinticinco de Mayo resumed regular service and was in 1983 modified to carry the new Dassault Super Étendard jets (which had turned out to be too heavy for the original catapult, which also barely got the F-8Qs into the air), but soon after problems in her engines largely confined her to port. She was deemed more or less unseaworthy and this confined the Argentinian Navy’s jet force to land bases.
From this point on, the F-8Qs lost their raison d’être, since the Argentinian air force already had, with the Mirage III and IAI Nesher/Dagger, capable and less costly land-based interceptors available. Due to lack of spares and funds, the remaining Argentinian Crusaders (after several accidents, only eight F-8Qs were still in service and only five of them actually operational) were in 1988 transferred to Villa Reynolds air base in Western Central Argentina, grounded and stored in the open, where they quickly deteriorated. Eventually, all F-8Qs were scrapped in the early Nineties. Only one specimen survived and has been preserved in its original Gull Grey/White livery as a gate guard at the Naval Aviation Command headquarters at Comandante Espora Airport, Bahía Blanca.

The kit and its assembly:
This relatively simple build was triggered by the “In the navy” group build at whatifmodelers.com in April/May 2020, even though I started it too late for the deadline.
After having recently read a lot of stuff about the Falklands/Malvinas conflict, I wondered if Argentina could not have procured a dedicated fighter for its single carrier – and the F-8 from US surplus stocks was a perfect candidate for the potential timeframe of the Seventies, when the type was retired from USN/USMC service or, in part, modernized and/or put up for sale, like the machines for the Philippines. The only real-world problem would have been the weight: the F-8E weighed up to 15 tons, while the Super Étendard, which was reportedly already hard to launch from Veinticinco de Mayo, had a MTOW of “only” 12 tons. Not certain if the F-8’s afterburner engine and the wings’ raised angle of incidence would have been enough to launch a Crusader? Well, it’s whifworld, after all. 😉
The basis is the Hasegawa F-8E, a kit that I had originally stashed away as a donor for a different project.
The model was built mostly OOB, I just sanded the dorsal avionics hump away and gave the machine a pair of drop tanks under the wings (from an A-4) – a rather unusual sight on a Crusader, and it looks even more weird with the wings in the raised position! The Sidewinders, relatively simple pieces, too, were taken OOB, since they look very much like early AIM-9Bs.
The kit goes together well, but it is a simple affair and you see the mold’s age. You get raised (though fine) panel lines, a rather simple cockpit tub with flat dashboards (for decals), a clumsy seat and no cockpit back wall at all. Fit is basically O.K., but the windscreen refused to fit well, and the hatch turned out to be somewhat too narrow for the rear bulkhead you are supposed to glue into it. Furthermore, the fuselage halves, especially on the underside, have shallow shrink areas close to the seams, so that PSR is mandatory. I would, not call the kit my first choice for the F-8 (which would rather be the Academy kit), but you get the Hasegawa kit at reasonable prices, and I originally purchased it as a body donor bank.
Since the kit lacks a proper air intake duct, sanding the fuselage halves inside of the respective orifice is not easy - I used a soft acrylic putty and left the radome away until the job was done. Furthermore, I added a visual blocker inside of the intake, a piece of black foamed styrene under the cockpit tub - otherwise you have direct sight down the empty interior in a head-on view.
Further small additions are some blade antennae on the hull and on the fin, inspired by the Argentinian Skyhawks.
Painting and markings:
Again, I wanted a rather subtle, semi-authentic look. The most natural choice would certainly have been a Light Gull Grey/White livery like the A-4Qs, but for a twist and because I like the late French F-8Ps in their all-over dark grey livery, I settled upon something that resembles the French/Argentinian Super Étendards: a dark, bluish-grey upper surface with white undersides and the upper colors well wrapped around the wings’ leading edges.
Concerning the French grey tone there are many different opinions and recommendations – ranging from Dark Gull Grey (FS 36231, which is IMHO much too light) over Gunship Grey (FS 36118) to dark blue.
I settled for Humbrol 79 (Blue Grey) as basic tone, which is AFAIK Humbrol’s interpretation of the German RAL 7012 (Basaltgrau), a tone that is very close to the British Dark Sea Grey. The undersides, including the landing gear, were painted with acrylic semi-gloss white from a rattle can. This was done as the first step, with a masked low waterline. Then the grey was applied by brush, and also wrapped around the wings’ leading edges. In order to improve the camouflage effect from above, the pylons as well as the outer sides of the stabilizers under the tail were painted in blue grey, too.
The flags on the rudder as well as the on the stabilizers were painted with white and Humbrol 48 (Mediterranean Blue), too, just the sun emblems on the fin are decals. Since the F-8 has, unlike the A-4 or the Sue, all-mowing stabilizers, I decided to paint the whole tail surface in white and blue and not just the trailing edge. This looks quite bright, but it is IMHO a great detail that sets this whif really apart and shows some pride.
The afterburner fairing was painted with a mix of Humbrol 27002 and 27003 (Polished Aluminum and Steel Metallizer) and later treated with graphite for a burnt look.
After an overall black ink wash the upper surfaces were treated with dry-brushed post shading (Humbrol 106 and 156). The decals come primarily from an Academy Super Étendard, augmented by markings from various decals from an Airfix Falklands War kit set sheet (e.g. the sun icons for the fin flash).
The silver leading edges of the wings, stabilizers and the fin were created with decal sheet material. the same material in black was used for walkway markings.
Decals come primarily from an Acedemy Super Étendard sheet, the tactical code was modified. Only the sun icons on the fin flash had to be procured from a different source (an Airfix A-4 Skyhawk sheet). The stencils come from the Hasegawa OOB sheet.
Finally, the kit received an all-over coat of matt acrlyic varnish.

The Château de Bourdeilles is located in a strategic location, on a rocky outcrop along the river "the dronne" near Brantôme in Périgord.
It began to be built in the 13th century.
There were, at the end of the medieval period two castles on the same site: Castle of the Counts of Périgord and of the barony of Bourdeilles property of the Kings of France, the site of the current Palais Renaissance.
We meet this twin configuration to other places in the region, as COMMARQUE.
From the late 14th century, the castle of the Barony is in ruins.
The medieval castle occupies the entire west terrace. It consists of a stately home with an octagonal keep, with a courtyard surrounded by high walls fortifiées.
Le dungeon is 35 meters high, with thick walls of 2.50 meters. From its peak, one has a breathtaking view of Bourdeilles.
The Renaissance palace was built from 1489 as artistic fashion brought by the Italian wars of "François 1er.
Its owner, Jacquette de Montbron, wife of André de Bourdeilles, had it built at great expense (it will be ruined). It hopes to receive Queen Catherine de Medici at the King's passing en route to Spain. A standing problem will not allow the royal couple to stop. The construction is then completed.
The castle pass into the hands of many owners before being property of the General Council.
The restoration of the castle started in 1967 by Mr. and Mrs. Santiard Bulteau-rich collectors and arts specialists in the period of "Charles V", which in exchange for a life usufruct to place their wonderful collection as a legacy to their death to the General Council. It is open to visitors.
Le château de Bourdeilles est situé à un emplacement stratégique, sur un éperon rocheux bordant la rivière « la dronne », près de Brantôme en Périgord.
Il a commencé à être bâti au 13ème siécle.
Il y eut, à la fin de l’époque médiévale deux chateaux sur le même site : le château des comtes du Périgord et celui de la baronnie de Bourdeilles propriété des Rois de france, à l’emplacement du Palais Renaissance actuel. On rencontre cette configuration jumelle à d’autres endroits dans la région, comme à COMMARQUE.
Dès la fin du 14ème siècle, le château de la Baronnie est en ruine.
Le château médiéval occupe toute la terrasse ouest. Il se compose d'un logis seigneurial avec un donjon octogonal, précédé d'une cour entourée de hautes murailles fortifiées.Le donjon est haut de 35 mètres, avec des murs épais de 2,50 mètres. De son sommet, on a une vue imprenable sur Bourdeilles.
Le palais Renaissance est construit à partir de 1489 selon la mode artistique apportée par les guerres d’Italie de « François 1er .
Sa propriétaire, Jacquette de Montbron, épouse d'André de Bourdeilles, l’a fait construire à grands frais (elle en sera ruinée). Elle espère y recevoir la reine Catherine de Médicis lors du passage du Roi en route vers l’Espagne. Un problème de date ne permettra pas au couple royal de s’y arrêter. La construction s’achèvera alors.
Le château passera aux mains de nombreux propriétaires avant d’être propriété du Conseil Général.
La restauration du château commence en 1967 grâce à Monsieur et Madame Santiard-Bulteau, riches collectionneurs d’arts et spécialistes de la période de « Charles Quint », qui en échange d’un usufruit à vie y placeront leur merveilleuse collection qu’ils lègueront à leur mort au Conseil Général. Il est ouvert à la visite.
The Supermarine Spitfire is a British single-seat fighter aircraft that was used by the Royal Air Force and many other Allied countries during and after the Second World War. The Spitfire was built in many variants, using several wing configurations, and was produced in greater numbers than any other British aircraft. It was also the only British fighter to be in continuous production throughout the war. The Spitfire continues to be a popular aircraft, with approximately 55 Spitfires being airworthy, while many more are static exhibits in aviation museums all over the world.
The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works (which operated as a subsidiary of Vickers-Armstrong from 1928). In accordance with its role as an interceptor, Mitchell designed the Spitfire's distinctive elliptical wing to have the thinnest possible cross-section; this thin wing enabled the Spitfire to have a higher top speed than several contemporary fighters, including the Hawker Hurricane. Mitchell continued to refine the design until his death from cancer in 1937, whereupon his colleague Joseph Smith took over as chief designer, overseeing the development of the Spitfire through its multitude of variants.
During the Battle of Britain (July–October 1940), the Spitfire was perceived by the public to be the RAF fighter, though the more numerous Hawker Hurricane shouldered a greater proportion of the burden against the Luftwaffe. However, because of its higher performance, Spitfire units had a lower attrition rate and a higher victory-to-loss ratio than those flying Hurricanes.
After the Battle of Britain, the Spitfire superseded the Hurricane to become the backbone of RAF Fighter Command, and saw action in the European, Mediterranean, Pacific and the South-East Asian theatres. Much loved by its pilots, the Spitfire served in several roles, including interceptor, photo-reconnaissance, fighter-bomber and trainer, and it continued to serve in these roles until the 1950s. The Seafire was a carrier-based adaptation of the Spitfire which served in the Fleet Air Arm from 1942 through to the mid-1950s. Although the original airframe was designed to be powered by a Rolls-Royce Merlin engine producing 1,030 hp (768 kW), it was strong enough and adaptable enough to use increasingly powerful Merlin and, in later marks, Rolls-Royce Griffon engines producing up to 2,340 hp (1,745 kW); as a consequence of this the Spitfire's performance and capabilities improved, sometimes dramatically, over the course of its life.
Mk V (Types 331, 349 & 352)
Spitfire LF.Mk VB, BL479, flown by Group Captain M.W.S Robinson, station commander of RAF Northolt, August 1943. This Spitfire has the wide bladed Rotol propeller, the internal armoured windscreen and "clipped" wings.
Late in 1940, the RAF predicted that the advent of the pressurised Junkers Ju 86P bomber series over Britain would be the start of a new sustained high altitude bombing offensive by the Luftwaffe, in which case development was put in hand for a pressurised version of the Spitfire, with a new version of the Merlin (the Mk VI). It would take some time to develop the new fighter and an emergency stop-gap measure was needed as soon as possible: this was the Mk V.
The basic Mk V was a Mk I with the Merlin 45 series engine. This engine delivered 1,440 hp (1,074 kW) at take-off, and incorporated a new single-speed single-stage supercharger design. Improvements to the carburettor also allowed the Spitfire to use zero gravity manoeuvres without any problems with fuel flow. Several Mk I and Mk II airframes were converted to Mk V standard by Supermarine and started equipping fighter units from early 1941. The majority of the Mk Vs were built at Castle Bromwich.
The VB became the main production version of the Mark Vs. Along with the new Merlin 45 series the B wing was fitted as standard. As production progressed changes were incorporated, some of which became standard on all later Spitfires. Production started with several Mk IBs which were converted to Mk VBs by Supermarine. Starting in early 1941 the round section exhaust stacks were changed to a "fishtail" type, marginally increasing exhaust thrust. Some late production VBs and VCs were fitted with six shorter exhaust stacks per side, similar to those of Spitfire IXs and Seafire IIIs; this was originally stipulated as applying specifically to VB(trop)s. After some initial problems with the original Mk I size oil coolers, a bigger oil cooler was fitted under the port wing; this could be recognised by a deeper housing with a circular entry. From mid-1941 alloy covered ailerons became a universal fitting.
Spitfire VC(trop), fitted with Vokes filters and "disc" wheels, of 417 Squadron RCAF in Tunisia in 1943.
A constant flow of modifications were made as production progressed. A "blown" cockpit hood, manufactured by Malcolm, was introduced in an effort to further increase the pilot's head-room and visibility. Many mid to late production VBs - and all VCs - used the modified, improved windscreen assembly with the integral bullet resistant centre panel and flat side screens introduced with the Mk III. Because the rear frame of this windscreen was taller than that of the earlier model the cockpit hoods were not interchangeable and could be distinguished by the wider rear framing on the hood used with the late-style windscreen.
Different propeller types were fitted, according to where the Spitfire V was built: Supermarine and Westland manufactured VBs and VCs used 10 ft 9 in (3.28 m) diameter, 3 bladed de Havilland constant speed units, with narrow metal blades, while Castle Bromwich manufactured VBs and VCs were fitted with a wide bladed Rotol constant speed propeller of either 10 ft 9 in (3.28 m) diameter, with metal blades, or (on late production Spitfires) 10 ft 3 in (3.12 m) diameter, with broader, "Jablo" (compressed wood) blades. The Rotol spinners were longer and more pointed than the de Havilland leading to a 3.5 in (8.9 cm) increase in overall length. The Rotol propellers allowed a modest speed increase over 20,000 ft (6,100 m) and an increase in the service ceiling. A large number of Spitfire VBs were fitted with "gun heater intensifier" systems on the exhaust stacks. These piped additional heated air into the gun bays. There was a short tubular intake on the front of the first stack and a narrow pipe led into the engine cowling from the rear exhaust.
The VB series were the first Spitfires able to carry a range of specially designed "slipper" drop tanks which were fitted underneath the wing centre-section. Small hooks were fitted, just forward of the inboard flaps: when the tank was released these hooks caught the trailing edge of the tank, swinging it clear of the fuselage.
With the advent of the superb Focke Wulf Fw 190 in August 1941 the Spitfire was for the first time truly outclassed, hastening the development of the "interim" Mk IX. In an effort to counter this threat, especially at lower altitudes, the VB was the first production version of the Spitfire to use "clipped" wingtips as an option, reducing the wingspan to 32 ft 2 in (9.8 m).The clipped wings increased the roll rate and airspeed at lower altitudes. Several different versions of the Merlin 45/50 family were used, including the Merlin 45M which had a smaller "cropped" supercharger impeller and boost increased to +18 lb. This engine produced 1,585 hp (1,182 kW) at 2,750 ft (838 m), increasing the L.F VB's maximum rate of climb to 4720 ft/min (21.6 m/s) at 2,000 ft (610 m).
VB Trop of 40 Squadron SAAF fitted with the "streamlined" version of the Aboukir filter, a broad-bladed, 10 ft 3 in (3.12 m) diameter Rotol propeller, and clipped wings.
The Mk VB(trop) (or type 352) could be identified by the large Vokes air filter fitted under the nose; the reduced speed of the air to the supercharger had a detrimental effect on the performance of the aircraft, reducing the top speed by 8 mph (13 km/h) and the climb rate by 600 ft/min (3.04 m/s), but the decreased performance was considered acceptable. This variant was also fitted with a larger oil tank and desert survival gear behind the pilot's seat. A new "desert" camouflage scheme was applied. Many VB(trop)s were modified by 103 MU (Maintenance Unit-RAF depots in which factory fresh aircraft were brought up to service standards before being delivered to squadrons) at Aboukir, Egypt by replacing the Vokes filter with locally manufactured "Aboukir" filters, which were lighter and more streamlined. Two designs of these filters can be identified in photos: one had a bulky, squared off filter housing while the other was more streamlined. These aircraft were usually fitted with the wide blade Rotol propeller and clipped wings.
Triumph Spitfire Mk I Roadster
The Triumph Spitfire is a small English two-seat sports car, introduced at the London Motor Show in 1962.[3] The vehicle was based on a design produced for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti. The platform for the car was largely based upon the chassis, engine, and running gear of the Triumph Herald saloon, and was manufactured at the Standard-Triumph works at Canley, in Coventry. As was typical for cars of this era, the bodywork was fitted onto a separate structural chassis, but for the Spitfire, which was designed as an open top or convertible sports car from the outset, the ladder chassis was reinforced for additional rigidity by the use of structural components within the bodywork. The Spitfire was provided with a manual hood for weather protection, the design improving to a folding hood for later models. Factory-manufactured hard-tops were also available.
The Triumph Spitfire was originally devised by Standard-Triumph to compete in the small sports car market that had opened up with the introduction of the Austin-Healey Sprite. The Sprite had used the basic drive train of the Austin A30/35 in a light body to make up a budget sports car; Triumph's idea was to use the mechanicals from their small saloon, the Herald, to underpin the new project. Triumph had one advantage, however; where the Austin A30 range was of unitary construction, the Herald featured a separate chassis. It was Triumph's intention to cut that chassis down and clothe it in a sports body, saving the costs of developing a completely new chassis / body unit.
Italian designer Michelotti—who had already penned the Herald—was commissioned for the new project, and came up with a traditional, swooping body. Wind-up windows were provided (in contrast to the Sprite/Midget, which still featured sidescreens, also called curtains, at that time), as well as a single-piece front end which tilted forwards to offer unrivaled access to the engine. At the dawn of the 1960s, however, Standard-Triumph was in deep financial trouble, and unable to put the new car into production; it was not until the company was taken over by the Leyland organization funds became available and the car was launched. Leyland officials, taking stock of their new acquisition, found Michelotti's prototype hiding under a dust sheet in a corner of the factory and rapidly approved it for production.

The production car changed little from the prototype, although the full-width rear bumper was dropped in favour of two part-bumpers curving round each corner, with overriders. Mechanicals were basically stock Herald. The engine was an 1,147 cc (1.1 l) 4-cylinder with a pushrod OHV cylinder head and 2 valves per cylinder, mildly tuned for the Spitfire, fed by twin SU carburettors. Also from the Herald came the rack and pinion steering and coil-and-wishbone front suspension up front, and at the rear a single transverse-leaf swing axle arrangement. This ended up being the most controversial part of the car: it was known to "tuck in" and cause violent over steer if pushed too hard, even in the staid Herald. In the sportier Spitfire (and later the 6-cylinder Triumph GT6 and Triumph Vitesse) it led to severe criticism. The body was bolted to a much-modified Herald chassis, the outer rails and the rear outriggers having been removed; little of the original Herald chassis design was left, and the Spitfire used structural outer sills to stiffen its body tub.
The Spitfire was an inexpensive small sports car and as such had very basic trim, including rubber mats and a large plastic steering wheel. These early cars were referred to both as "Triumph Spitfire Mark I" and "Spitfire 4", not to be confused with the later Spitfire Mark IV.
In UK specification the in-line four produced 63 bhp (47 kW) at 5750 rpm, and 67 lb·ft (91 N·m)of torque at 3500 rpm. This gave a top speed of 92 mph (148 km/h), and would achieve 0 to 60 mph (97 km/h) in 17.3 seconds. Average fuel consumption was 31mpg.
For 1964 an overdrive option was added to the 4-speed manual gearbox to give more relaxed cruising. Wire wheels and a hard top were also available.

This is actually the cane configuration I found I liked best after finishing the cane and playing around with it...
(cont.) ...MDOT has altered the configuration of this interchange, for the major benefit of this one specific off-ramp to boot. There are now three lanes here, and the traffic signal controls two. There's still the one lane that turns left (302 west, to Horn Lake), but there's also a dedicated right-turn lane at the stoplight, which takes you to the northern portion of Southcrest Parkway (leading to the hospital, hence the blue “H” tacked atop the sign here. Personally, I believe the “H” ought to have been made a permanent part of the sign itself, or MDOT could even have had the sign read “Hospital” in addition to the relatively lesser-known “Southcrest Pkwy,” but I digress.). Then, you've also got the existing “country,” non-signalized right-turn lane that has also been allowed to remain intact.
Why the two right-turn lanes? Well, to solve the issue of the drivers sweeping across mulitple lanes of traffic, of course! On Goodman Road itself – which we'll see momentarily – the large center median has been removed, in favor of new, parking-lot-bumper-style barricades. These barricades serve to essentially “trap” drivers in the lanes they are in. That sounds like it's a bad thing, but I promise, it's not! (cont.)

On July 25, 1962, NASA invited 11 firms to submit proposals for the LEM. Of the 11 invited, 9 submitted proposals. The firms that submitted proposals were Lockheed, Boeing, Northrop, Ling-Temco-Vought, Grumman, Douglas, General Dynamics Convair, Republic, and Martin Marietta. Grumman won.
Convair's proposed vehicle featured a single throttleable main engine backed by two standby thrust chambers. It was to be a partially staged configuration with a side-by-side crew arrangement and a probe-drogue docking mechanism. The lower structure held the descent tankage, which was to be depressurized 15 seconds prior to touchdown. The depressurized tankage, along with the crushable vehicle skirt, were to offer a back-up to the landing system in the event of a landing accident.
The engines were protected against landing damage through use of a crushable main engine nozzle skirt and the placement of the standby engines above the descent tankage. The reaction control thrusters were mounted on hinged arms, which folded 120 degrees to allow the vehicle to be stowed in the SIVB stage of the Saturn V rocket.
The concept was derived from studies of the probability of successful abort and complete mission success. Although the studies indicated that a multiple engine, two-stage vehicle had higher safety characteristics at higher levels of landing damage, Convair chose the stage and a half configuration due to the lower weight requirement.
Docking was to have been achieved by a probe and drogue mechanism. The method was to allow the crew to take advantage of good visibility and not have to change positions. Controls, displays and cues would not change during docking. Once the probe was aligned with the drogue, it would be locked in place, and the LEM rotated 90 degrees for final mating and crew transfer.

Some background:
The Cessna Model 336 and 337 “Skymaster” were American twin-engine civil utility aircraft built in a unique push-pull configuration. Their engines were mounted in the nose and rear of its pod-style fuselage. Twin booms extended aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer was aft of the pusher propeller, mounted between and connecting the two booms.
The first Skymaster, Model 336, had fixed landing gear and initially flew on February 28, 1961. It went into production in May 1963 with 195 being produced through mid-1964. In February 1965, Cessna introduced the larger Model 337 Super Skymaster with more powerful engines, retractable landing gear, and a dorsal air scoop for the rear engine (the "Super" prefix was subsequently dropped from the name). In 1966, the turbocharged T337 was introduced, and in 1973, the pressurized P337G entered production.
The type was very prolific and Cessna built 2.993 Skymasters of all variants, including 513 military O-2 (nicknamed "Oscar Deuce") versions from 1967 onwards. The latter featured underwing ordnance hard points to hold unguided rockets, gun pods or flares, and served in the forward air control (FAC) role and psychological operations (PSYOPS) by the US military between 1967 and 2010. Production in America ended in 1982, but was continued by Reims in France, with the FTB337 STOL and the military FTMA “Milirole”.
Both civil and military Cessna 336/337 version had long service careers, and some were considerably modified for new operators and uses. Among the most drastic conversions was the Spectrum SA-550, built by Spectrum Aircraft Corporation of Van Nuys, California, in the mid-1980s: Spectrum took the 336/337 airframe and removed the front engine, lengthened the nose to maintain the center of gravity, and replaced the rear piston engine with a pusher turboprop which offered more power than the combined pair of original petrol engines. The Spectrum SA-550 conversion also came together with an optional modernization package that prolonged the airframes’ service life, so that modified machines could well serve on for 20 years or more.
This drastic conversion was executed for both military and civil operators. The best-known military SA-550s were six former USAF O-2A airframes, which had been transferred to the U.S. Navy in 1983 for use as range controllers with VA-122 at NAS Lemoore, California. These aircraft were operationally nicknamed “Pelican”, due to the characteristic new nose shape, and the name unofficially caught on.
However, the SA-550 package was only adopted sporadically by private operators, but it became quite popular among several major police and fire departments. Typical duties for these machines included border/drug patrol, surveillance/observation duties (e.g. traffic, forest fire) and special tasks, including drug interdiction as well for SAR missions and undercover operations like narcotics and serialized criminal investigations. Some SA-550s were accordingly modified and individually outfitted with suitable sensors, including IR/low light cameras, searchlights, and internal auxiliary tanks. None were armed, even though some aircraft featured underwing hardpoints for external extra tanks, flare dispensers for nocturnal operations or smoke charge dispensers for ground target marking to guide water bombers to hidden forest fires.
The type’s versatility, low noise level, high travel speed and good loitering time in the operational area at low speed proved to be vital assets for these public service operators and justified its relatively high maintenance costs. A handful of the modernized Spectrum SA-550 machines were still in active service after the Millennium, primarily in the USA.

The kit and its assembly:
This build is the combination of ingredients that had already been stashed away for a long time, and the “Red Lights” Group Build at whatifmodellers.com in early 2021 was a good motivator and occasion to finally put everything together.
The basis is an ARII 1:72 Cessna T337 model kit – I had purchased it long ago with the expectation to create a military Skymaster from it, but I was confused by a fixed landing gear which would make it a 336? Well, without a further concrete plan the kit preliminarily landed in The Stash™…
However, the ARII model features the optional observation windows in the doors on the starboard side, in the form of a complete(!) fuselage half, so that it lends itself to a police or firefighter aircraft of some sort. This idea was furthermore fueled by a decal sheet that I had been given from a friend, left over from a 1:72 Italeri JetRanger, with three optional police helicopter markings.
The final creative element was the real-world “Pelican” conversion of six O-2As for the US Navy, as mentioned in the background above: the front engine was replaced with a longer nose and the engine configuration changed to a pusher-only aircraft with a single powerful turboprop engine. This looked so odd that I wanted to modify the ARII Cessna in a similar fashion, too, and all these factors came together in this model.
My Arii Cessna 337 kit is a re-boxing from 2009, but its origins date back to Eidai in 1972 and that’s just what you get: a vintage thing with some flash and sinkholes, raised (but fine) surface details and pretty crude seams with bulges and gaps. Some PSR is direly necessary, esp. the fit of the fuselage halves is cringeworthy. The clear parts were no source of joy, either; especially the windscreen turned out to be thick, very streaky (to a degree that I’d almost call it opaque!) and even not fully molded! The side glazing was also not very clear. I tried to improve the situation through polishing, but if the basis is already poor, there’s little you can do about it. Hrmpf.
However, the kit was built mostly OOB, including the extra O-2 glazing in the lower doors, but with some mods. One is a (barely visible) extra tank in the cabin’s rear, plus a pilot and an observer figure placed into the tight front seats. The extended “Pelican” nose was a lucky find – I was afraid that I had had to sculpt a nose from scratch with 2C putty. But I found a radome from a Hasegawa RA-5C, left over from a model I built in the Eighties and that has since long fallen apart. However, this nose fitted almost perfectly in size and shape, I just “blunted” the tip a little. Additionally, both the hull in front of the dashboard and the Vigilante radome were filled with as many lead beads as possible to keep the nose down.
The kit’s OOB spatted, fixed landing gear was retained – even though it is dubious for a Cessna 337, because this type had a fully retractable landing gear, and the model has the landing gear covers actually molded into the lower fuselage. On the other side, the Cessna 336’s fixed landing gear looks quite different, too! However, this is a what-if model, and a fixed landing gear might have been a measure to reduce maintenance costs?
The propeller was replaced with a resin four-blade aftermarket piece (from CMK, probably the best-fitting thing on this build!) on my standard metal axis/styrene tube adapter arrangement. The propeller belongs to a Shorts Tucano, but I think that it works well on the converted Cessna and its powerful pusher engine, even though in the real world, the SA-550 is AFAIK driven by a three-blade prop. For the different engine I also enlarged the dorsal air intake with a 1.5 mm piece of styrene sheet added on top of the molded original air scoop and added a pair of ventral exhaust stubs (scratched from sprue material).
Another addition is a pair of winglets, made from 0.5 mm styrene sheet – an upgrade which I found on several late Cessna 337s in various versions. They just add to the modernized look of the aircraft. For the intended observation role, a hemispherical fairing under the nose hides a 180° camera, and I added some antennae around the hull.
However, a final word concerning the model kit itself: nothing fits, be warned! While the kit is a simple affair and looks quite good in the box, assembling it turned out to be a nightmare, with flash, sinkholes, a brittle styrene and gaps everywhere. This includes the clear parts, which are pretty thick and blurry. The worst thing is the windscreen, which is not only EXTRA thick and EXTRA blurry, it was also not completely molded, with gaps on both sides. I tried to get it clearer through manual polishing, but the streaky blurs are integral – no hope for improvement unless you completely replace the parts! If I ever build a Cessna 337/O-2 again, I will give the Airfix kit a try, it can only be better…
Painting and markings:
The choice between the operator options from the JetRanger sheet was hard, it included Sweden and Italy, but I eventually settled for the LAPD because the livery looks cool and this police department not only operates helicopters, but also some fixed-wing aircraft.
I adapted the LAPD’s classic black-and-white police helicopter livery (Gloss White and Black, Humbrol 22 and 21, respectively) to the Cessna and extended it to the wings. At this point – already upset because of the poor fit of the hardware – disaster struck in the form of Humbrol’s 22 turning into a pinkish ivory upon curing! In the tin, the paint and its pigments looked pretty white and “clean”, and I assume that it’s the thinner that caused this change. What a crap! It’s probably the third tin with 22 that causes trouble, even though in different peculiarities!
The result was total rubbish, though, and I tried to rub the paint off as good as possible on the small model with its many windows, the fixed, delicate landing gear and the wing support struts. Then I overpainted the areas with Revell 301 (Semi-matt White). While this enamel yielded the intended pure white tone, the paint itself is rather gooey and not easy to work with, so that the overall finish turned out worse than desired. At least the black paint worked properly. The demarcations were created with black decal stripes (TL Modellbau), because the tiny model left little room for complex masking measures – and I did not risk any more painting accidents.
Since the aircraft would be kept shiny and clean, I just did a light black ink washing to emphasize surface details and did a light panel post-shading on the black areas, not for weathering but rather to accent surface structures. No further weathering was done (and necessary).
The markings/decals come – as mentioned above – from an Italeri 1:72 JetRanger, but they were augmented with some additional markings, e. g. grey walkways on the wings and “L-A-P-D” in large black letters under the wings, to distract from the poor finish of the white paint around them…
Finally, the kit was sealed overall with Italeri semi-gloss acrylic varnish, just with a matt anti-glare shield in front of the windscreen, which received thin white trim lines (generic decal stripes).
A challenging build due to the Arii kit’s rather poor basis, the massive rhinoplasty and the crisp paint scheme. However, I like the result – what-if models do not always have to be armed military vehicles, there’s potential in other genres, too. And this mono-engine “Pelican” Skymaster plays its role as a “flying eye” in police service credibly and well. However, this was my first and last Eidai kit…

The side glazing was also not very clear. I tried to improve the situation through polishing, but if the basis is already poor, there’s little you can do about it. Hrmpf.
However, the kit was built mostly OOB, including the extra O-2 glazing in the lower doors, but with some mods. One is a (barely visible) extra tank in the cabin’s rear, plus a pilot and an observer figure placed into the tight front seats. The extended “Pelican” nose was a lucky find – I was afraid that I had had to sculpt a nose from scratch with 2C putty. But I found a radome from a Hasegawa RA-5C, left over from a model I built in the Eighties and that has since long fallen apart. However, this nose fitted almost perfectly in size and shape, I just “blunted” the tip a little. Additionally, both the hull in front of the dashboard and the Vigilante radome were filled with as many lead beads as possible to keep the nose down.
The kit’s OOB spatted, fixed landing gear was retained – even though it is dubious for a Cessna 337, because this type had a fully retractable landing gear, and the model has the landing gear covers actually molded into the lower fuselage. On the other side, the Cessna 336’s fixed landing gear looks quite different, too! However, this is a what-if model, and a fixed landing gear might have been a measure to reduce maintenance costs?
The propeller was replaced with a resin four-blade aftermarket piece (from CMK, probably the best-fitting thing on this build!) on my standard metal axis/styrene tube adapter arrangement. The propeller belongs to a Shorts Tucano, but I think that it works well on the converted Cessna and its powerful pusher engine, even though in the real world, the SA-550 is AFAIK driven by a three-blade prop. For the different engine I also enlarged the dorsal air intake with a 1.5 mm piece of styrene sheet added on top of the molded original air scoop and added a pair of ventral exhaust stubs (scratched from sprue material).
Another addition is a pair of winglets, made from 0.5 mm styrene sheet – an upgrade which I found on several late Cessna 337s in various versions. They just add to the modernized look of the aircraft. For the intended observation role, a hemispherical fairing under the nose hides a 180° camera, and I added some antennae around the hull.
However, a final word concerning the model kit itself: nothing fits, be warned! While the kit is a simple affair and looks quite good in the box, assembling it turned out to be a nightmare, with flash, sinkholes, a brittle styrene and gaps everywhere. This includes the clear parts, which are pretty thick and blurry. The worst thing is the windscreen, which is not only EXTRA thick and EXTRA blurry, it was also not completely molded, with gaps on both sides. I tried to get it clearer through manual polishing, but the streaky blurs are integral – no hope for improvement unless you completely replace the parts! If I ever build a Cessna 337/O-2 again, I will give the Airfix kit a try, it can only be better…
Painting and markings:
The choice between the operator options from the JetRanger sheet was hard, it included Sweden and Italy, but I eventually settled for the LAPD because the livery looks cool and this police department not only operates helicopters, but also some fixed-wing aircraft.
I adapted the LAPD’s classic black-and-white police helicopter livery (Gloss White and Black, Humbrol 22 and 21, respectively) to the Cessna and extended it to the wings. At this point – already upset because of the poor fit of the hardware – disaster struck in the form of Humbrol’s 22 turning into a pinkish ivory upon curing! In the tin, the paint and its pigments looked pretty white and “clean”, and I assume that it’s the thinner that caused this change. What a crap! It’s probably the third tin with 22 that causes trouble, even though in different peculiarities!
The result was total rubbish, though, and I tried to rub the paint off as good as possible on the small model with its many windows, the fixed, delicate landing gear and the wing support struts. Then I overpainted the areas with Revell 301 (Semi-matt White). While this enamel yielded the intended pure white tone, the paint itself is rather gooey and not easy to work with, so that the overall finish turned out worse than desired. At least the black paint worked properly. The demarcations were created with black decal stripes (TL Modellbau), because the tiny model left little room for complex masking measures – and I did not risk any more painting accidents.
Since the aircraft would be kept shiny and clean, I just did a light black ink washing to emphasize surface details and did a light panel post-shading on the black areas, not for weathering but rather to accent surface structures. No further weathering was done (and necessary).
The markings/decals come – as mentioned above – from an Italeri 1:72 JetRanger, but they were augmented with some additional markings, e. g. grey walkways on the wings and “L-A-P-D” in large black letters under the wings, to distract from the poor finish of the white paint around them…
Finally, the kit was sealed overall with Italeri semi-gloss acrylic varnish, just with a matt anti-glare shield in front of the windscreen, which received thin white trim lines (generic decal stripes).
A challenging build due to the Arii kit’s rather poor basis, the massive rhinoplasty and the crisp paint scheme. However, I like the result – what-if models do not always have to be armed military vehicles, there’s potential in other genres, too. And this mono-engine “Pelican” Skymaster plays its role as a “flying eye” in police service credibly and well. However, this was my first and last Eidai kit…

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 Cessna Model 336 and 337 “Skymaster” were American twin-engine civil utility aircraft built in a unique push-pull configuration. Their engines were mounted in the nose and rear of its pod-style fuselage. Twin booms extended aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer was aft of the pusher propeller, mounted between and connecting the two booms.
The first Skymaster, Model 336, had fixed landing gear and initially flew on February 28, 1961. It went into production in May 1963 with 195 being produced through mid-1964. In February 1965, Cessna introduced the larger Model 337 Super Skymaster with more powerful engines, retractable landing gear, and a dorsal air scoop for the rear engine (the "Super" prefix was subsequently dropped from the name). In 1966, the turbocharged T337 was introduced, and in 1973, the pressurized P337G entered production.
The type was very prolific and Cessna built 2.993 Skymasters of all variants, including 513 military O-2 (nicknamed "Oscar Deuce") versions from 1967 onwards. The latter featured underwing ordnance hard points to hold unguided rockets, gun pods or flares, and served in the forward air control (FAC) role and psychological operations (PSYOPS) by the US military between 1967 and 2010. Production in America ended in 1982, but was continued by Reims in France, with the FTB337 STOL and the military FTMA “Milirole”.
Both civil and military Cessna 336/337 version had long service careers, and some were considerably modified for new operators and uses. Among the most drastic conversions was the Spectrum SA-550, built by Spectrum Aircraft Corporation of Van Nuys, California, in the mid-1980s: Spectrum took the 336/337 airframe and removed the front engine, lengthened the nose to maintain the center of gravity, and replaced the rear piston engine with a pusher turboprop which offered more power than the combined pair of original petrol engines. The Spectrum SA-550 conversion also came together with an optional modernization package that prolonged the airframes’ service life, so that modified machines could well serve on for 20 years or more.
This drastic conversion was executed for both military and civil operators. The best-known military SA-550s were six former USAF O-2A airframes, which had been transferred to the U.S. Navy in 1983 for use as range controllers with VA-122 at NAS Lemoore, California. These aircraft were operationally nicknamed “Pelican”, due to the characteristic new nose shape, and the name unofficially caught on.
However, the SA-550 package was only adopted sporadically by private operators, but it became quite popular among several major police and fire departments. Typical duties for these machines included border/drug patrol, surveillance/observation duties (e.g. traffic, forest fire) and special tasks, including drug interdiction as well for SAR missions and undercover operations like narcotics and serialized criminal investigations. Some SA-550s were accordingly modified and individually outfitted with suitable sensors, including IR/low light cameras, searchlights, and internal auxiliary tanks. None were armed, even though some aircraft featured underwing hardpoints for external extra tanks, flare dispensers for nocturnal operations or smoke charge dispensers for ground target marking to guide water bombers to hidden forest fires.
The type’s versatility, low noise level, high travel speed and good loitering time in the operational area at low speed proved to be vital assets for these public service operators and justified its relatively high maintenance costs. A handful of the modernized Spectrum SA-550 machines were still in active service after the Millennium, primarily in the USA.

The kit and its assembly:
This build is the combination of ingredients that had already been stashed away for a long time, and the “Red Lights” Group Build at whatifmodellers.com in early 2021 was a good motivator and occasion to finally put everything together.
The basis is an ARII 1:72 Cessna T337 model kit – I had purchased it long ago with the expectation to create a military Skymaster from it, but I was confused by a fixed landing gear which would make it a 336? Well, without a further concrete plan the kit preliminarily landed in The Stash™…
However, the ARII model features the optional observation windows in the doors on the starboard side, in the form of a complete(!) fuselage half, so that it lends itself to a police or firefighter aircraft of some sort. This idea was furthermore fueled by a decal sheet that I had been given from a friend, left over from a 1:72 Italeri JetRanger, with three optional police helicopter markings.
The final creative element was the real-world “Pelican” conversion of six O-2As for the US Navy, as mentioned in the background above: the front engine was replaced with a longer nose and the engine configuration changed to a pusher-only aircraft with a single powerful turboprop engine. This looked so odd that I wanted to modify the ARII Cessna in a similar fashion, too, and all these factors came together in this model.
My Arii Cessna 337 kit is a re-boxing from 2009, but its origins date back to Eidai in 1972 and that’s just what you get: a vintage thing with some flash and sinkholes, raised (but fine) surface details and pretty crude seams with bulges and gaps. Some PSR is direly necessary, esp. the fit of the fuselage halves is cringeworthy. The clear parts were no source of joy, either; especially the windscreen turned out to be thick, very streaky (to a degree that I’d almost call it opaque!) and even not fully molded! The side glazing was also not very clear. I tried to improve the situation through polishing, but if the basis is already poor, there’s little you can do about it. Hrmpf.
However, the kit was built mostly OOB, including the extra O-2 glazing in the lower doors, but with some mods.

This includes the clear parts, which are pretty thick and blurry.
