Originally required as a navigation trainer for the RAF, the military conversion of the eleven-passenger Lockheed Model 14 Super Electra promised so much in performance that the decision was made in 1938 to order the type for the RAF off the drawing board as the Model 214 Hudson.

The Lockheed Martin F-35 – or the Joint Strike Fighter as it was initially known - represents potentially the single largess and most ambitious military aircraft development for many years and is aimed at providing one aircraft to meet the requirements of a number of military services.

General Hirschauer, the Director of military aviation in France in 1915, sought that the Farman brothers, Henry and Maurice, design an aircraft to replace the MF-7 and MF-11 and they designed it around a cockpit which was ovoid in shape and was suspended between the wings and had a more

Late in World War II the Fiat company in Italy designed the G-55 Centauro single-seat fighter powered by the Daimler Benz DB-605 12-cylinder VEE liquid-cooled engine, and this aircraft, although built in relatively small numbers, fought very successfully with the Fascist Republican Airforce.

One of the most successful military turbojet powered trainers, the Magister was produced in large numbers, some 437 being completed for the French Air Force, and it was licence built, being produced in Finland by Valmet OY (62), Israel by Israel Aircraft Industries (36), and West Germany by Flugzeug Union

The DO 24 was a tri motor, high-wing all metal construction cantilever flying boat with sponsons, the latter containing much of the fuel which was fed to gravity tanks in the wings.

The Fairey III was a very successful military general purpose biplane of the1920s which was built in a variety of models.

Designed as a private venture, the de Havilland Vampire two-seat trainer was a development of the Vampire single-seat fighter-bomber. Known as the DH-115 Vampire T.11, the first of two prototypes (G-5-7 – later WW456) was flown for the first time on 15 November 1950.

In the late 1930’s the RAAF was operating a small fleet of Supermarine Seagull V biplanes for reconnaissance, air-sea rescue, and general operations and was having problems keeping the aircraft airworthy. The wings were built of metal and with operations on salt water corrosion was causing problems.

In 1971 Hawker Siddeley and British Aerospace were selected to design and build the HS.1182 trainer for the RAF, and since then more than 700 examples have been supplied to many of the Worlds airforces in a variety of models.
