Brief description: This picture gallery contains aircraft models of World War II on a scale 1:72 as injection moulded, resin- and vacu- formed kits as well as home-made conversions.
Here, you will find photos of aircraft models of World War II on a scale 1:72. e.g. those of the United States Army Air Force (USAAF), the United States Navy (USN), the Royal Air Force (RAF), the Royal Navy (RN) , the Imperial Japanese Army Air Force (IJAAF), the Imperial Japanese Navy Air Force (IJNAF), the German Air Force (Luftwaffe, GAF) and the Air Force of the Soviet Union. Within these branches of the services you can select between fighters, fighter-bombers, bombers, trainers etc. Also you can select projects, designed on the drawing board as well as post-war developments, whose origin dated back into the time of WW II.
Important notice: Among the aircraft models shown here there are many aircraft from the former German Air Force (Deutsche Luftwaffe). They all show the swastika as a national symbol of that time. I would like to point out that this is not a political statement, but rather a source of historical information on the types of aircraft flown by the German Luftwaffe before and during the Second World War. It is to be taken as a reference for all aviation enthusiasts, and not taken as an expression of any sympathy for the Nazi regime or any Neo-Nazi or Right wing hate Groups.
I have built all these models just for fun and never, it has been my intention to show them anybody or to present them at a show. Over the years more then 1.500 models have emerged, and many more kits have not been completed yet, or are still waiting for the finish or the last little detail.
POWER PLANT: Jacob R-915-3 radial engine, rated at 300 hp
PERFORMANCE: 110 mph
COMMENT: The Kellett YO-60 was a military derivative of the civil Kellet KD-1 autogyro built by the Kellett Autogiro Company by order of the United States Army in the late 1930. It had the distinction of being the first practical rotary-wing aircraft used by the United States Army and inaugurated the first scheduled air-mail service using a rotary-wing aircraft.
Using the experience gained in building Cierva autogyros under license the Kellett Autogiro Company developed the KD-1 which was similar to the contemporary Cierva C.30. It had two open cockpits, a fixed tailwheel landing gear and was powered by a 225 hp Jacobs L-4 radial engine. After testing of the prototype a commercial variant designated the Kellett KD-1A was put into production. The KD-1A had a three-bladed rotor with folding blades and a number of minor detail improvements. A KD-1B which was a KD-1A with an enclosed cockpit for the pilot was operated by Eastern Airlines and inaugurated the first scheduled rotary-wing air-mail service on July 1939.
In 1935 the United States Army bought a KD-1 for evaluation and designated it Kellett YG-1, a second aircraft followed which had additional radio equipment and was designated the Kellett YG-1A. These two aircraft were followed by a batch of seven designated Kellett YG-1B.
In 1942 seven more aircraft were bought by the US Army Air Force for use in the observation role as the Kellet XO-60. During initial test phase several improvements were incorporated compared to the KD-1. A new style clutch had discs and used a planetary reduction gear system at the engine with a larger drive shaft running directly from the power takeoff on the engine to the rotor head and the pilot was put in the front seat and added a transparent plastic cover over both cockpits and a large transparent plastic panel in the belly beneath the pilot’s feet. The observer’s seat could swivel so he could ride backwards and work at a small table behind the rear seat. When the observer was not in place, ballast had to be carried in the rear cockpit. Furthermore, the power plant was changed to a Jacobs R-915-3, seven cylinder, air-cooled, radial engine providing 330hp through a Hamilton-Standard constant speed propeller and the engine mount was removable at the firewall. In this way a quick change power plant package could be stocked. The fuselage structure was similar to the earlier KD-1/YG-1. The fairing was different with flatter sides giving the observer better downward vision out the side windows. The enclosure over the two cockpits hinged open and slid to the right to permit entrance and exit from the cockpits on the left.
The model was soon changed from Kellett XO-60 to YO-60 and seven were built. Only six were delivered, one was damaged in a run-up accident and was not repaired.
One YG-1B was modified with a constant-speed rotor and was re-designated the Kellett YG-1C, it was later re-engined with the more powerful R-915 and re-designated again as the Kellett XR-2. The XR-2 was destroyed by rotor ground resonance problems and the evaluation was continued with another modified YG-1B designated the Kellett XR-3. In total app. 24 Kellett autogyros were built for the US Army Air Force.
One Kellet KD-1A been imported to Japan in 1939 and was prototype for the Kayaba Ka-1 and Ka-2 autogyro (Ref. 24).
POWER PLANT: Two BMW 801A radial engines, rated at 1,539 hp each
PERFORMANCE: 385 mph at 20,800 ft
COMMENT: The Focke-Wulf Fw 191 was a prototype German bomber of WW II, as the Focke-Wulf firm’s entry for the Bomber B advanced medium bomber design competition. Two versions were intended to be produced, a twin-engine version using the Junkers Jumo 222 engine and a four-engine variant which was to have used the smaller Daimler-Benz DB 605 engine. The project was eventually abandoned due to technical difficulties with the engines
In July 1939, the RLM issued a specification for a high-performance medium bomber (the “Bomber B” program). It was to have a maximum speed of 370 mph and be able to carry a bomb load of 4,000 kg to any part of Britain from bases in France or Norway. Furthermore, the new bomber was to have a pressurized crew compartment, of the then-generalized “stepless cockpit” design (with no separate windscreen for the pilot) pioneered by the Heinkel He 111P shortly before the war and used on most German bombers during the war, remotely controlled armament, and was to utilize two of the new 2,466 hp class of engines then being developed (Jumo 222 or DB 604), with the Jumo 222 being specified for the great majority of such twin-engined designs, that Arado, Dornier, Focke-Wulf and Junkers had created airframe designs to use. The Arado Ar E340 was eliminated. The Dornier Do 317 was put on a low-priority development contract; and the Junkers Ju 288 and Focke-Wulf Fw 191 were chosen for full development.
Overall, the Fw 191 was a clean, all-metal aircraft that featured a shoulder-mounted wing. Two 24-cylinder Junkers Jumo 222 engines (which showed more promise than the DB 604 engines) were mounted in nacelles on the wings. An interesting feature was the inclusion of the Multhopp-Klappe, an ingenious form of combined landing flap and dive brake fitted in four sections to the wing trailing edges, which was developed by engineer H. Multhopp. The entire fuel supply was carried in five tanks located above the internal bomb bay, and in two tanks in the wing between the engine nacelles and fuselage.
The tail section was of a twin fins and rudders design, with the tailplane having a small amount of dihedral. The main landing gear legs retracted to the rear and rotated 90° to lie flat in each engine nacelle with the mainwheels resting atop the lower ends of the gear struts when fully retracted, much like the main gear on the production versions of the Junkers Ju 88 already did. Also, the tailwheel retracted forwards into the fuselage. A crew of four sat in the pressurized cockpit, and a large Plexiglas dome was provided for the navigator; the radio operator could also use this dome to aim the remotely controlled rear guns.
The Fw 191 followed established Luftwaffe practice in concentrating the crew in the nose compartment, also including the nearly ubiquitous “Bola”, inverted-casemate undernose gondola for defensive weapons mounts first used on the Junkers Ju 88A before the war, and in the use of a “stepless cockpit”, having no separate windscreen for the pilot, as the later -P and -H versions of the Heinkel He 111 already did. This was pressurised for high-altitude operations. The proposed operational armament consisted of one 20 mm MG 151 cannon in a chin turret, twin 20 mm MG 151 in a remotely controlled dorsal turret, twin 20 mm MG 151 in a remotely controlled ventral turret, a tail turret with one or two machine guns and remotely controlled weapons in the rear of the engine nacelles. However, different combinations were mounted in the prototype aircraft. Sighting stations were provided above the crew compartment, as well as at the ends of the aforementioned “Bola” beneath the nose.
The aircraft had an internal bomb bay. In addition, bombs or torpedoes could be carried on external racks between the fuselage and the engine nacelles. The design was to have had a maximum speed of 370 mph, a bomb load of 4,000 kg, and a range allowing it to bomb any target in Britain from bases in France and Norway.
It is said that the intention to use electric power for almost all of the aircraft’s auxiliary systems (also a fact for the successful Focke-Wulf Fw 190 fighter), requiring the installation of a large number of electric motors and wiring led to the nickname for the Fw 191 of “Das fliegende Kraftwerk” (the flying power station). This also had the detrimental effect of adding even more weight to the overburdened airframe, plus there was also the danger of a single enemy bullet putting every system out of action if the generator was hit. On its maiden flight early in 1942, the Focke-Wulf Fw 191 V1 showed immediate problems arising from the lower rated engines not providing enough power, as was anticipated. Additional problems occurred with the Multhopp-Klappe, which presented severe flutter problems when extended, and pointed to the need for a redesign. At this point, only dummy gun installations were fitted and no bomb load was carried. After completing ten test flights, the Fw 191 V1 was joined by the similar V2, but only a total of ten hours of test flight time was logged. The 2,466 hp Junkers Jumo 222 engines which would have powered the Fw 191 proved troublesome. In total only three prototype aircraft, V1, V2 and V6, were built. The project was crippled by engine problems and an extensive use of electrical motor-driven systems. Problems arose almost immediately when the Junkers Jumo 222 engines were not ready in time for the first flight tests, so a pair of 1,539 hp BMW 801A radial engines was fitted. This made the Fw 191 V1 seriously underpowered. Another problem arose with the RLM’s insistence that all systems that would normally be hydraulic or mechanically activated should be operated by electric motors.
At this point, the RLM allowed the redesign and removal of the electric motors (to be replaced by the standard hydraulics), so the Fw 191 V3, V4 and V5 were abandoned. The Fw 191 V6 was then modified to the new design, and also a pair of specially prepared Junkers Jumo 222 engines were fitted that developed 2,170 hp for takeoff. The first flight of the new Fw 191 took place in December 1942. Although the V6 flew better, the Junkers Jumo 222 was still not producing their design power, and the whole Jumo 222 development prospect was looking bad due to the shortage of special metals for it. The Fw 191 V6 was to have been the production prototype for the Fw 191A series.
Due to the German aviation engine industry having ongoing problems in producing power plant designs capable of output levels matching or exceeding the 2,100 hp figure throughout the entirety of the war years, that had any demonstrable level of combat-ready reliability, the Jumo 222 engines were having a lot of teething problems, and the Daimler Benz DB 604 had already been abandoned, a new proposal was put forth for the Fw 191B series.
The Fw 191 V7 through V12 machines were abandoned in favor of using the Fw 191 V13 to install a pair of Daimler Benz DB 606 or 610 “power system” engines, which were basically coupled pairs of either DB 601 or 605 12-cylinder engines. Their lower power-to-weight ratio, however, from their 1.500 kg weight apiece for each “power system”, meant that the armament and payload would have to be reduced. It had already been decided to delete the engine nacelle gun turrets, and to make the rest manually operated. Five more prototypes were planned with the new engine arrangement, V14 through V18, but none were ever built, possibly from the August 1942 condemnation by Reichsmarschall H. Göring of the coupled “power system” DB 606 and 610 power plants as “welded-together engines, in regards to their being the primary cause of the unending series of power plant problems in their primary use, as the engines on Heinkel’s He 177A “Greif”, Germany’s only production heavy bomber of World War II.
One final attempt was made to save the Focke-Wulf Fw 191 program, this time the Fw 191C was proposed as a four engined aircraft, using either the 1,322 hp Junkers Jumo 211F, the 1,332 hp Daimler-Benz DB 601E, the 1,455 hp Daimler-Benz DB 605A or similar rated DB 628 engines. Also, the cabin would be unpressurized and the guns manually operated, with a rear step in the bottom of the deepened fuselage — in the manner of the near-ubiquitous “Bola” gondola used by the majority of German bombers for ventral defense under the nose — being provided for the gunner.
However, at this time, the whole “Bomber B” program had been canceled, due mainly to no engines of the 2,500 hp class being available, which was one of the primary requirements in the “Bomber B” program. Although the Fw 191 will be remembered as a failure, the air frame and overall design eventually proved themselves to be sound; only the underpowered engines and insistence on electric motors to operate all the systems eventually doomed the aircraft. All in all, there were only three Focke-Wulf Fw 191s ever built (V1, V2 and V6), and no examples of the Fw 191B or C ever advanced past the design stage. The RLM kept in reserve for Focke-Wulf the future number: Fw 391 for follow-up designs, but nothing ever developed. The project was eventually scrapped (Ref.: 24).
POWER PLANT: One Hitachi “Amakaze” radial engine, rated at 300 hp
PERFORMANCE: 132 mph
COMMENT: The Yokosuka K5Y2 was a two-seat unequal-span biplane trainer (Allied reporting name “Willow”) that served in the Imperial Japanese Navy during World War II. Due to its bright orange paint scheme (applied to all Japanese military trainers for visibility), it earned the nickname “Red dragonfly”, after a type of insect common throughout Japan.
The aircraft was based on the Yokosuka Navy Type 91 Intermediate Trainer, but stability problems led to a redesign by Kawanishi in 1933. It entered service in 1934 as Navy Type 93 Intermediate Trainer K5Y1 with fixed tail-skid landing gear, and remained in use throughout the war. Floatplane types K5Y2 and K5Y3 were also produced. After the initial 60 examples by Kawanishi, production was continued by Watanabe (556 aircraft built), Mitsubishi (60), Hitachi (1,393), First Naval Air Technical Arsenal (75), Nakajima (24), Nippon (2,733), and Fuji (896), for a total of 5,770. These aircraft were the mainstay of Imperial Japanese Navy Air Service’s flight training’s, and as intermediate trainers, they were capable of performing demanding aerobatic maneuvers. Two further land-based versions, the K5Y4 with a 480 hp “Amakaze” 21A engine and the K5Y5 with a 515 hp “Amakaze” 15, were projected but never built.
A K5Y of the Kamikaze Special Attack Corps 3rd Ryuko Squadron was credited with sinking the destroyer USS Callaghan on July 29, 1945, the last US warship lost to kamikaze attack during the war (Ref.: 24).
POWER PLANT: Four Wright R-1820-97 Cyclone supercharged radial engines, rated at 1,200 hp each
PERFORMANCE: 287 mph
COMMENT: The Boeing B-17 “Flying Fortress” was a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry (prototype Model 299, XB-17) outperformed both competitors and exceeded the air corps’ performance specifications. Although Boeing lost the contract (to the Douglas B-18 “Bolo”) because the prototype crashed, the air corps ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 “Flying Fortress” evolved through numerous design advances becoming the third-most produced bomber of all time, behind the American four-engined Consolidated B-24 “Liberator” and the German multirole, twin-engined Junkers Ju 88.
On 8 August 1934, the USAAC tendered a proposal for a multiengine bomber to replace the Martin B-10. The Air Corps was looking for a bomber capable of reinforcing the air forces in Hawaii, Panama, and Alaska. Requirements were for it to carry a “useful bombload” at an altitude of 10,000 ft, a range of 2,000 mi and a top speed of at least 250 mph was desired.
The prototype XB-17, with the Boeing factory designation of Model 299, was built at Boeing’s own expense. It combined features of the company’s experimental XB-15 bomber and Model 247 transport. The first flight of the Model 299 was on July 1935 and on 20 August 1935, the prototype flew from Seattle to Wright Field in nine hours and three minutes with an average cruising speed of 252 miles per hour, much faster than the competition.
The USAAC had been impressed by the prototype’s performance, and on January 1936, through a legal loophole, the air corps ordered 13 YB-17s (designated Y1B-17 after November 1936 to denote its special F-1 funding) for service testing.
The YB-17 incorporated a number of significant changes from the Model 299, including more powerful Wright R-1820-39 Cyclone engines. Although the prototype was company-owned and never received a military serial (the B-17 designation itself did not appear officially until January 1936, nearly three months after the prototype crashed), the term “XB-17” was retroactively applied to the airframe and has entered the lexicon to describe the first “Flying Fortress”.
Opposition to the air corps’ ambitions for the acquisition of more B-17s faded, and in late 1937, 10 more aircraft designated B-17B were ordered to equip two bombardment groups, one on each U.S. coast. Improved with larger flaps and rudder and a well-framed, 10-panel plexiglas nose, the B-17Bs were delivered in five small batches between July 1939 and March 1940. In July 1940, an order for 512 B-17s was issued, but at the time of the attack on Pearl Harbor, fewer than 200 were in service with the army.
The aircraft went through several alterations in each of its design stages and variants. Of the 13 YB-17s ordered for service testing, 12 were used by the 2nd Bomb Group of Langley Field, Virginia, to develop heavy bombing techniques, and the 13th was used for flight testing at the Material Division at Wright Field, Ohio. Experiments on this aircraft led to the use of a quartet of General Electric turbo-superchargers which would become standard on the B-17 line
As the production line developed, Boeing engineers continued to improve upon the basic design. To enhance performance at slower speeds, the B-17B was altered to include larger rudders and flaps. The B-17C changed from three bulged, oval-shaped machine gun blisters to two flush, oval-shaped machine gun window openings, and on the lower fuselage, a single “bathtub” machine gun gondola housing, which resembled the similarly configured and located ventral defensive emplacement on the German Heinkel He 111P-series medium bomber.
While models A through D of the B-17 were designed defensively, the large-tailed B-17E was the first model primarily focused on offensive warfare. The B-17E was an extensive revision of the Model 299 design: The fuselage was extended by 10 ft; a much larger rear fuselage, vertical tailfin, rudder, and horizontal stabilizer were added to the design; a gunner’s position was added in the new tail; the nose (especially the bombardier’s well-framed, 10-panel nose glazing) remained relatively the same as the earlier B through D versions had, but with the addition of a Sperry electrically powered manned dorsal gun turret just behind the cockpit, and the similarly powered Sperry-built manned ventral ball turret just aft of the bomb bay. The B-17’s turbocharged Wright R-1820 Cyclone 9 engines were upgraded to increasingly more powerful versions of the same power plants multiple times throughout its production, and similarly, the number of machine gun emplacement locations was increased to enhance the aircraft’s combat effectiveness.
In April 1942, the B-17F was introduced onto the production lines, and outwardly this variant differed from the B-17E only in having an extended Plexiglas nose which was frameless except for the optically flat bomb-aiming panel, paddle-blade airscrews for maximum operating performance, extra fuel cells, improvements of the bomb stowage, brake system, communications equipment and oxygen system. As the cross weight was increased, the undercarriage was strengthened.
Owing to the constant modifications being applied to aircraft on the production lines and the immense scale of production orders, a system of “Block Designations” was instituted. Thus, the first Boeing-built B-17F Fortress became B-17F-1-BO, and all aircraft in this production block were identical insofar as equipment and installations were concerned. Blocks B-17F-5-BO, -10-BO, etc., followed, the intervening number being left to indicate subsequent changes made at modification centres. Production of the B-17F continued for 15 months, during which 2,300 were built by Boeing, 600 by Douglas (suffix DL) and 500 by Locked Vega (suffix VE). The final production blocks of the B-17F from Douglas’ plants did, however, adopt the Bendix “chin turret” with two machine guns, giving them a much-improved forward defense capability.
The B-17F variants were the primary versions flying for the Eighth Air Force to face the Germans in 1943. The maximum bomb load of the first B-17F was 4.350 kg, but on typical missions to Germany, Eighth Air Force Fortresses carried 1.800- 2.270 kg over operating ranges averaging 1,400 miles. Beyond these distances, the bomb load fell rapidly, so that the effective combat radius of B-17F was about a maximum of 800 miles. Later modifications already referred to increase the fuel capacity as well as bomb load and by that the USAAF was enabled to build up an immense striking force in the European Theatre of Operations (Ref.: 4, 24).
POWER PLANT: Two Junkers Jumo 004B-1 turbojet engines, rated at 900 kp each
PERFORMANCE: 461 mph at 20,000 ft
COMMENT: In late 1940, the Reichsluftfahrtministerium (RLM, Reich Air Ministry), offered a tender for a jet-powered high-speed reconnaissance aircraft with a range of 1,340 mi. Arado was the only company to respond, offering their E.370 project, a high-wing conventional-looking design with a Junkers Jumo 004 tubojet engine under each wing.
Arado estimated a maximum speed of 480 mph at 20,000 ft, an operating altitude of 36,000 ft and a range of 1,240 mi. The range was short of the RLM request, but they liked the design and ordered two prototypes as the Arado Ar 234. These were largely complete before the end of 1941, but the Jumo 004 engines were not ready, and would not be ready until February 1943. When they did arrive they were considered unreliable by Junkers for in-flight use and were cleared for static and taxi tests only. Flight-qualified engines were finally delivered, and the first prototype, the Ar 234 V1 made its first flight on July 1943 at Rheine Airfield.
By September 1943, four prototypes were flying and four more prototypes under construction. The sixth and eighth aircraft of the series were powered with four BMW 003 turbojet engines instead of two Jumo 004s, the sixth having four engines housed in individual nacelles and the eighth flown with two pairs of BMW 003s installed within “twinned” nacelles underneath either wing. These were the first four-engine jet aircraft to fly.
The projected weight for the aircraft was approximately 8 tonnes. To reduce the weight of the aircraft and maximize the internal fuel the eight prototype aircraft were fitted with the original arrangement of trolley-and-skid landing gear, intended for the planned operational, but never-produced Arado Ar 234A version.
Arado did not use the typical retractable landing gear. Instead, the aircraft was to take off from a jettisonable three-wheeled, tricycle gear-style trolley and land on three retractable skids, one under the central section of the fuselage, and one under each engine nacelle.
The RLM had already seen the promise of the design and in July 1943 had asked Arado to supply two prototypes of a “Schnellbomber” (“Fast bomber”) version as the Arado Ar 234B. Since the original skid-equipped Ar 234A’s fuselage design was very slender and filled with fuel tanks, there was no room for an internal bomb bay and the bombload had to be carried on external racks.
Since the cockpit was directly in front of the fuselage, the pilot had no direct view to the rear, so the guns were aimed through a periscope, derived from the type used on German World War II tanks, mounted on the cockpit roof. The Ar 234B version was modified to have fully retractable tricycle landing gear, with the mid-fuselage very slightly widened to accommodate the forward-retracting main gear units, the nose gear retracting rearwards. The first twin-Jumo 004 powered prototype Ar 234B (V 7) flew on 10 March 1944 for the first time and made history on 2 August 1944 as the first jet aircraft ever to fly a reconnaissance mission.
Production B-series aircraft were slightly wider at mid-fuselage to house the main landing gear, with a central fuel tank present (the middle one of a trio of fuel tanks) in the mid-fuselage location forward tank, central and an aft. Under tests with maximum bombload consisting of three SC 500 bomb, the Ar 234 V9 aircraft could reach 418 mph at 16,000 ft. This was still better than any bomber the Luftwaffe had at the time, and made it the only bomber with any hope of surviving the massive Allied air forces. The normal bombload consisted of two 500 kg bombs suspended from the engines or one large 1,000 kg bomb semi-recessed in the underside of the fuselage with maximum bombload being 1,500 kg. In case the full bomb load was to be deployed on an Ar 234B for an operational sortie, fuel had to be reduced and two Walter HWK 109-500A-1 “Starthilfe” (Take-off assistance) liquid fuel jettisonable JATO rocket pods delivering 500kp thrust each were fixed under each wing.
Production lines were already being set up, and 20 Arado Ar 234B-0 pre-production aircraft were delivered by the end of June 1943. Later production was slow, as the Arado plants were given the simultaneous tasks of producing aircraft from other bombed-out factories hit during the USAAF’s “Big Week”, and the ongoing license-building and nascent phasing-out of Heinkel’s heavy He 177A bomber, even as the Arado firm was intended to be the sole subcontractor for the Heinkel He 177B (He 277) series strategic bomber, meant to start construction at Arado as early as October 1944. Meanwhile, several of the Ar 234 prototypes – including a few of the surviving six twin-engine Jumo 004-powered “trolley-and-skids” Ar 234A-series prototypes – were sent forward in the reconnaissance role. In most cases, it appears they were never even detected, cruising at about 460 mph at over 29,900 ft, with the seventh prototype achieving the first-ever wartime reconnaissance mission over the United Kingdom by a Luftwaffe-used jet aircraft.
The few 234Bs entered service in autumn and impressed their pilots. They were fairly fast and completely aerobatic. The long takeoff runs led to several accidents; a search for a solution led to improved training as well as the use of two jettisonable RATO units. The Jumo 004 engines were always the real problem; they suffered constant flameouts and required overhaul or replacement after about 10 hours of operation.
The most notable use of the Arado Ar 234 in the bomber role was the attempt to destroy the Ludendorff Bridge at Remagen. The aircraft continued to fight in a scattered fashion until Germany surrendered on 8 May 1945. Some were shot down in air combat, destroyed by flak, or “bounced” by Allied fighters during takeoff or on the landing approach, as was already happening to Messerschmitt Me 262 jet fighters. Mostly the remaining aircraft sat on the airfields awaiting fuel that never arrived.
Overall from mid-1944 until the end of the war a total of 210 aircraft were built. In February 1945, production was switched to the Arado Ar 234C variant. It was hoped that by November 1945 production would reach 500 per month. Only a few of this four engine aircraft were built before Germany finally collapsed (Ref.: 24).
POWER PLANT: Two Heinkel-Hirth HeS 011 turbojet engines, rated at 1,300 kp thrust each
PERFORMANCE: High subsonic speed, estimated
COMMENT: In early 1941 several high speed versions of the basic Messerschmitt Me 262 were designed on the drawing board. The first of these “Hochgeschwindigkeitsjäger” (HG), (High-speed fighter) was the Messerschmitt Me 262 V9, unofficially called HG I. This aircraft featured modified wing leading edges of the inner wing section, swept angles of stabilizers, and a “Rennkabine” (Racing canopy), shallow, low-drag cockpit canopy and windscreen with low profile.
Other two projects were created following this way: The Me 262 HG II called for an outboard wing of increased chord and an improved air intake and engine installation, and finally the Me 262 HG III, which was the final stage of development. It required more radical modifications, as a new 45 degree swept wing with engines housed in the wing roots. Three variants of the Me 262 HG III are known correspond to the original layout.
Entwurf 1” (Concept 1) had a the original tail plane of the Me 262, “Entwurf 2” (Concept 2) had a butterfly-type tail plane, and “Entwurf 3” (Concept 3) together with various subtypes was considerably altered in the fuselage area, where the cockpit was relocated at the rear and formed a part of the empennage group. The swept back stabilizers were located behind the cockpit. This Messerschmitt Me 262 HG III/ Concept 3 attained a very high state of fighter technology, which in the post-war period was the only realized abroad after a passage of several years.
POWER PLANT: One Aichi Atsuta Type 32 liquid-cooled engine, rated at 1,400 hp
PERFORMANCE: 310 mph at 17,060 ft
COMMENT:The Aichi M6A1-K “Seiran Kai” was a trainer version of the submarine-launched attack floatplane Aichi M6A1 “Seiran”. It was fitted with an inwardly-retracting undercarriage, and the folding tip of the rudder was dispensed with as the absence of floats improved directional stability. The popular name of the M6A1-K was later changed to “Nanzan” (Southern Mountain”).
Two prototypes of this aircraft were built and flight tested before the war in the Pacific ended in 1945 (Ref.: 24).
POWER PLANT: Four Pratt & Whitney R-1830-43 Twin Wasp radial engines, rated at 1,200 hp each
PERFORMANCE: 303 mph at 25,000 ft
COMMENT: The Consolidated B-24 “Liberator was a heavy long-range bomber of the USAAF during WW II and large aircraft for its day. It had a wing span of 110 feet and a gross weight of more than 30 tons. Powered by four 1,200 hp radial engines, it had a maximum fuel capacity of 2,814 US gallons and the bomb load varied from 2,000 to 4,000 kp depending on the distance of the target to be attacked. The crew varied from eight to 10 men, five or six of whom acted as gunners, manning the 10 machine guns usually carried for defence.
The operating technique with these heavy bombers was, after take-off, to assemble large formations of from 20 to 40 aircraft while climbing to operational altitude of 20,000 to 25,000 feet. This was coordinated by means of “Assembly Ships” (or “Formation Ships”) specially fitted to aid assembly of individual group formations. They were equipped with signal lighting, provision for quantity discharge of pyrotechnics, and were painted with distinctive group-specific high-contrast patterns of stripes, checkers or polka dots to enable easy recognition by their flock of bombers. The aircraft used in most cases were veteran B-24Ds. All armament and armor was removed and arrangements for signal lighting varied from group to group, but generally consisted of white flashing lamps on both sides of the fuselage arranged to form the identification letter of the group. Such an assembly was despatched from a single airfield and joined with other formations to form a division column of perhaps 500 to 600 bombers.
The 446th Bombardment Group (H) with Component Squadrons 784th, 785th, 786th and 787th Bombardment Squadron (H) was activated on 1 Aug. 1943 at Alamogordo AAFd. NM. The training for combat commenced at Kearns Fd. Utah end Aug. 43, remaining there until Nov, 43, when the group moved back to Alamogordo AAFd, NM. In early Feb. 44 the group moved to Topeka AAFd, Kan and after a week’s stay began movement to the UK. Here the group was stationed at Attlebridge, Norfolk, for the last year of the war in Europe.
Combat aircraft were Consolidated B-24H, B-24J, B-24L and B-24M. In total the group flew 232 missions in the course of the year against strategic objectives like U-boat installations in Kiel, ball bearing works in Berlin, aircraft factories in Munich and oil refineries in Hamburg. Remarkably, the 785th Bomb Squadron flew 55 consecutive missions without loss. The aircraft shown here is the assembly ship of the 446th Bombardment Group. It’s a veteran Consolidated B-24D named “Striped Ass” (Ref: 2).
Notice: Identification markings of this aircraft are mostly hand-made. After airbrushing the surface with different aluminum-silver shading red stripes are applied according to the original. For this I used microthin precision slit tape, Bishop Graphics. Inc., Westlake Village, Ca. This is self-adhesive, in red color, extreme thin and easy to apply. Unfortunately transparent it needed to be painted stripe by stripe before being applied.
POWER PLANT: One Heinkel-Hirth HeS 011 turbojet engine, rated at 1,300 kp
PERFORMANCE: 630 mph
COMMENT: In Autumn 1944, in the context of the “Jägernotprogramm” (“Emergency Fighter Program”) the Oberkommando der Luftwaffe (OKL, Luftwaffe High Command) requested for proposals for a new generation of fighter/interceptor aircraft in order to replace the Heinkel He 162 “Salamander” or “Volksjäger” (“Peoples fighter”).
Besides designs such as Blohm & Voss Bv P.212, Focke-Wulf Ta 183, Heinkel He P. 1078, and Junkers EF 128 Messerschmitt proposed its project Me P. 1110 with three different variants.
First of the designs was the Messerschmitt Me P.1110/I, a turbo-jet powered interceptor with a conventional-looking design with the air intakes located in the middle part of fuselage sides above the wing the inlet not protruding the cross section (“Rampen-Einlauf”, “Ramp-air-intake”). The wing was of wooden construction and was swept back to 60 degree at the wing root and 40 degree at the leading edge. The tail plane was conventional with elevators and a vertical fin and swept back. Power was provided by a Heinkel/Hirth HeS 011 turbojet engine. A pressurized cockpit with streamlined fairing, tricycle landing gear and three MK 108 30mm cannon in the nose with a provision for two more in the wing roots was envisaged.
The second design was the Messerschmitt Me P.1110/II that differed from the Me P.1110/I mainly in a V-tail unit and a divided annular air intake behind the cockpit. The advantage of this unusual arrangement was that it would reduce drag by fifteen percent compared to a single nose air intake at the cost of four percent air flow reduction to the jet engines. To increase the air flow a supercharger was provided that additionally withdraw the boundary layer.
Like the Me P.1110/I, the Me P.1110/II had 40 degree swept-back wings, an HeS 011 jet engine and was armed with three MK 108 30mm cannon in the nose with a provision for two more in the wing roots.
The third design the Messerschmitt Me P.1110 “Ente” was of canard configuration with small wings in the front and larger wings in the rear part of the fuselage.
All projects would be soon dropped in favor of the Junkers EF 128 and none of the Messerschmitt designs made it to the prototype stage. (Ref.: 20, 22).
POWER PLANT: Two Bristol “Centaurus” IX radial engines, rated at 2,520 hp each
PERFORMANCE: 336 mph at 12,000 ft
COMMENT : In early 1939 Bristol suggested a bomber variant of the “Beaufighter” with their Bristol “Hercules” engines. British policy at the time was an expectation for medium bombers to be provided from the US allowing British industry to concentrate on heavy bomber designs but a design was requested preferably based on an existing design which meant working with the Bristol “Beaufort” or “Beaufighter”.
Air Ministry specification B.7/40 called for a medium bomber to replace the Bristol “Blenheim”. The specification stipulated a speed of at least 300 mph at 5,000 ft, a normal load of 500 kg of bombs and a center turret armed with at least two 12.7 mm machine guns. Only Armstrong Whitworth Company tendered a full design but it did not meet with approval. So when Bristol brought their Type 162 (tentatively named “Beaumont”), which was fortunately well matched to B.7/40 specification, to the Air Staff, this led to a request to complete a mockup in 1940 and then a confirmed contract for three prototypes in February 1941. The “Beaumont” was based on the rear fuselage and tail of a “Beaufighter”, with a new center and front fuselage. The armament was a mid-upper turret with four machine guns, four more machine guns firing forward and two firing to the rear.
Construction began in late 1940, with a new Air Ministry Specification B.2/41 to be written around it. Changes in the requirements, removing dive bombing and ground attack support which incoming US bombers were expected to be capable of and increasing the performance to allow for the future, meant the “Beaumont” would no longer suffice. The changes in performance, requiring a bomb load of 4,000 lb, a speed of 360 mph and a range of 1,600 miles meant a redesign by Bristol to use the Bristol “Centaurus” engine.
The Bristol redesign with a larger wing and the more powerful engines was the Bristol ”Buckingham”. It had gun installations in the nose, dorsal and ventral turrets. Generally conventional in appearance, one unusual feature was that the bomb-aimer/navigator was housed in a mid-fuselage ventral gondola, resembling those on the earlier German Heinkel He 111H and American Boeing B-17C and -D in appearance. This was part of an attempt to give all the crew positions unobstructed views and access to each other’s positions. The bomb bay could hold up to 2,000 kg bombs. The rear of the gondola had a hydraulically powered turret with two Browning machine guns. The Bristol-designed dorsal turret carried four Brownings. A further four fixed, forward-firing Brownings were controlled by the pilot. Following more changes, specification B.2/41 was replaced by B.P/41. An order for 400, at an initial rate of 25 per month, was made with deliveries expected in March 1943. The first flight took place on 4 February 1943. During testing, the “Buckingham” exhibited poor stability which led to the enlargement of the twin fins, along with other modifications. The Bristol “Buckingham B1” was first flown 12 February 1944 with “Centarus” VI or XI engines, 400 ordered but reduced first to 300 then to 119, with only 54 built as bombers. Overtaken by events, it was mainly used primarily for transport and liaison duties (Ref.: 24).
