The Airspeed AS.10 Oxford was a twin-engine monoplane aircraft developed and manufactured by Airspeed . It saw widespread use for training British Commonwealth aircrews in navigation , radio-operating , bombing and gunnery roles throughout the Second World War . The Oxford was developed by Airspeed during the 1930s in response to a requirement for a capable trainer aircraft that conformed with Specification T.23/36 , which had been issued by the British Air Ministry . Its basic design is derived from the company 's earlier AS.6 Envoy , a commercial passenger aircraft . Performing its maiden flight on 19 June 1937 , it was quickly put into production as part of a rapid expansion of the Royal Air Force ( RAF ) in anticipation of a large-scale conflict . As a consequence of the outbreak of war , many thousands of Oxfords would be ordered by Britain and its allies , including Australia , Canada , France , New Zealand , Poland , and the United States . Following the end of the conflict , the Oxford continued to achieve export sales for some time , equipping the newly formed air forces of Egypt , India , Israel , and Yugoslavia . It was considered to be a capable trainer aircraft throughout the conflict , as well as being used a general-purpose type . A large number of Oxfords have been preserved on static display .
The Avro Anson is a British twin-engined , multi-role aircraft built by the aircraft manufacturer Avro . Large numbers of the type served in a variety of roles for the Royal Air Force ( RAF ) , Fleet Air Arm ( FAA ) , Royal Canadian Air Force ( RCAF ) and numerous other air forces before , during , and after the Second World War . Initially known as the Avro 652A , the Anson was developed during the mid-1930s from the earlier Avro 652 airliner in response to a request for tenders issued by the British Air Ministry for a maritime reconnaissance aircraft . Having suitably impressed the Ministry , a single prototype was ordered , which conducted its maiden flight on 24 March 1935 . Following an evaluation in which the Type 652A bettered the competing de Havilland DH.89 , it was selected as the winner , leading to Air Ministry Specification 18/35 being written around the type and an initial order for 174 aircraft being ordered in July 1935 . The Type 652A was promptly named after British Admiral George Anson . The type was placed into service with the Royal Air Force ( RAF ) and was initially used in the envisioned maritime reconnaissance operation alongside the larger flying boats . After the outbreak of the Second World War the Anson was soon found to have become obsolete in front line combat roles . Large numbers of the type were instead put to use as a multi-engined aircrew trainer , having been found to be suitable for the role , and became the mainstay of the British Commonwealth Air Training Plan . The type continued to be used in this role throughout and after the conflict , remaining in RAF service as a trainer and communications aircraft until 28 June 1968 . During the post-war climate , the Anson was increasingly produced for the civil market , being used as a light transport and executive aircraft . By the end of production in 1952 , a total of 8,138 Ansons had been constructed by Avro in nine variants ; in addition , a further 2,882 aircraft were manufactured by Federal Aircraft Ltd in Canada from 1941 .
The Blackburn B.26 Botha was a British four-seat reconnaissance and torpedo bomber . It was built by Blackburn Aircraft at its factories at Brough and Dumbarton , as a competitor to the Bristol Beaufort , entering service with the RAF in 1939 . The design was underpowered and it was quickly withdrawn from operations .
The Bristol Buckmaster was an advanced British training aircraft operated by the Royal Air Force during the 1950s .
The Beechcraft AT-10 Wichita was an American World War II trainer built for the United States Army Air Forces ( USAAF ) by Beechcraft and the Globe Aircraft Corporation . It was used to train pilots for multi-engined aircraft such as bombers .
The Cessna AT-17 Bobcat is a twin-engined advanced trainer aircraft designed and made in the United States , and used during World War II to bridge the gap between single-engined trainers and twin-engined combat aircraft . The AT-17 was powered by two Jacobs R-755-9 radial engines . The commercial version was the Model T-50 , from which the AT-17 was developed .
The Consolidated C-87 Liberator Express was a transport derivative of the B-24 Liberator heavy bomber built during World War II for the United States Army Air Forces . A total of 287 C-87s were built alongside the B-24 at the Consolidated Aircraft plant in Fort Worth , Texas . The plant also developed and delivered a USAAF flight engineer trainer designated as the AT-22 , a United States Navy VIP transport designated as the RY , and a Royal Air Force VIP transport designated as the Liberator C.IX . The last development was a Navy contracted , single tail version with an extended fuselage . Built in San Diego , its USN designation was RY-3 . In contrast , the C-109 Liberator was a fuel-transport converted from existing B-24 Bombers .
The CANT Z.1007 Alcione ( Kingfisher ) was an Italian three-engined medium bomber , with wooden structure . Designed by Filippo Zappata , who also designed the CANT Z.506 it had excellent flying characteristics and good stability and was regarded by some as the best Italian bomber of World War II although its wooden structure was easily damaged by the climate , as experienced in North Africa and in Russia . It was used by the Italian Regia Aeronautica , Italian Co-Belligerent Air Force , Aeronautica Nazionale Repubblicana and Luftwaffe during World War II .
The Curtiss-Wright AT-9 Jeep was a twin-engined advanced trainer aircraft used by the United States during World War II to bridge the gap between single-engined trainers and twin-engined combat aircraft . The AT-9 had a low-wing cantilever monoplane configuration , retractable landing gear and was powered by two Lycoming R-680-9 radial engines .
During summer 1933 , the de Havilland aircraft company commenced work upon an aircraft to meet an Australian requirement , producing a four-engined faster passenger aircraft capable of seating ten passengers , the DH.86 Dragon Express . An important feature of the DH.86 was the newly developed and powerful Gipsy Six engine , a six-cylinder variant of the four cylinder Gipsy Major engine . The DH.86 would serve as the a key starting point for the later DH.89 . During late 1933 , a team at de Havilland , led by aircraft designer Arthur Ernest Hagg , began working on a new design , intended to be a faster and more comfortable successor to the earlier DH.84 Dragon . The new aircraft was , in effect , a twin-engined , scaled-down version of the four-engined DH.86 Express . It shared many common features with the earlier DH.86 Express , including its tapered wings , streamlined fairings and fuselage , as well as the same Gipsy Six engines . However , the DH.89 demonstrated none of the operational vices of the Express . On 17 April 1934 , the prototype conducted its maiden flight at Hatfield Aerodrome , Hertfordshire . Flown by senior de Havilland test pilot H.S . Broad , it was powered by a pair of 200 horsepower ( 150 kW ) Gypsy Six engines . Even prior to the prototype 's first flight , plans to proceed with serial production of DH.89 had already received the go-ahead from management . During May 1934 , airworthiness trials commenced at RAF Martlesham Heath using the prototype ; during one such flight , upon attaining a speed of roughly 175 miles per hour ( 282 km/h ) , the tip of the aircraft 's nose buckled .
The Fairchild AT-21 was an American World War II specialized bomber crew trainer , intended to train crews in the use of power gun turrets or a gun on a flexible mount , as well as learn to function as a member of a crew . It had a brief career as a training aircraft before modified bombers took over this role .
The Fairey Aviation Company Fairey III was a family of British reconnaissance biplanes that enjoyed a very long production and service history in both landplane and seaplane variants . First flying on 14 September 1917 , examples were still in use during the Second World War .
The Fairey Battle was a British single-engine light bomber designed and manufactured by the Fairey Aviation Company . It was developed during the mid-1930s for the Royal Air Force ( RAF ) as a monoplane successor to the Hawker Hart and Hind biplanes . The Battle was powered by the same high-performance Rolls-Royce Merlin piston engine that powered various contemporary British fighters like the Hawker Hurricane and Supermarine Spitfire . The Battle was much heavier , with its three-man crew and bomb load . Though a great improvement over the aircraft that preceded it , the Battle was relatively slow and limited in range . With only two .303 in machine guns as defensive armament , it was found to be highly vulnerable to enemy fighters and anti-aircraft fire . The Fairey Battle was used on operations early in the Second World War . During the Phoney War the type achieved the distinction of attaining the first aerial victory of an RAF aircraft in the conflict . In May 1940 , the Battles of the Advanced Air Striking Force suffered many losses , frequently in excess of 50 percent of aircraft sorties per mission . By the end of 1940 the type had been withdrawn from front-line service and relegated to training units overseas . As an aircraft that had been considered to hold great promise in the pre-war era , the Battle proved to be one of the most disappointing aircraft in RAF service .
The Fairey Gordon was a British light bomber ( 2-seat day bomber ) and utility aircraft of the 1930s . The Gordon was a conventional two-bay fabric-covered metal biplane . It was powered by 525-605 horsepower ( 391-451 kW ) variants of the Armstrong Siddeley Panther IIa engine . Armament was one fixed , forward-firing .303-inch ( 7.7 mm ) Vickers machine gun and a .303-inch ( 7.7 mm ) Lewis Gun in the rear cockpit , plus 500 pounds ( 230 kg ) of bombs . The aircraft was somewhat basic ; instruments were airspeed indicator , altimeter , oil pressure gauge , tachometer , turn and bank indicator and compass .
The Fleet Model 60K Fort was the only aircraft designed and built by Canadians during the Second World War and was also the first all-metal monoplane built by Fleet Aircraft of Canada ( Fort Erie ) . It was intended to be an intermediate trainer employed for pilot training between the de Havilland Tiger Moth primary trainer and the North American Harvard advanced trainer . Although it served with the British Commonwealth Air Training Plan , the Fort was redundant and was used to train wireless ( radio ) operators and had a relatively short operational career .
The Focke-Wulf Fw 58 Weihe ( Harrier ) was a German aircraft , built to fill a request by the Luftwaffe for a multi-role aircraft , to be used as an advanced trainer for pilots , gunners and radio operators .
Hanriot H.230 was a French twin-engined advanced trainer . The construction of the aircraft was initiated in 1936 by Hanriot 's chief designer Montlaur . The aircraft was produced by the nationalized factory SNCAC .
The Hawker Henley was a British two-seat target tug derived from the Hawker Hurricane that was operated by the RAF during the Second World War .
The Kyushu K10W Type 2 Land based intermediate trainer ( Code Named Oak by the Allies ) was a single engine low wing fixed undercarriage monoplane training aircraft which served in the Imperial Japanese Navy Air Service in the latter part of World War II .
The Kyūshū K11W Shiragiku ( 白菊 , White Chrysanthemum ) made by the Kyūshū Aircraft Company , was a land-based bombing trainer aircraft which served in the Imperial Japanese Navy Air Service in the latter years of World War II . As indicated by its Japanese designation , training aircraft for on-board work ( 機上作業練習機 , kijō sagyō renshū-ki ? ) , it was designed to train crews in operating equipment for bombing , navigation , and communication , as well as navigation techniques . A total of 798 K11Ws were manufactured , including a small number of K11W2 ASW and transport aircraft alongside the K11W1 trainer variant . These aircraft were also used in kamikaze mission during the last stages of the Pacific War .
