The Ilyushin Il-102 was an experimental jet powered ground-attack aircraft designed by Ilyushin. This aircraft was never chosen for production, being surpassed by the Su-25, and only a few development prototypes were built.

[edit] Design and development

In 1967, the Soviet Air Forces drew up a specification for a jet powered shturmovik or armoured ground attack aircraft. While Sukhoi designed an all-new single seat aircraft, the Su-25, Ilyushin proposed a modified version of their Il-40 of 1953 under the designation Il-42, which unlike the Sukhoi was a two seat aircraft with a remotely controlled rear gun turret. The design was rejected by the Soviet Air Forces, but Ilyushin decided to continue development as a private venture, renaming the programme Il-102.^[1]

The Il-102 first prototype flew on 25 September 1982, with a second airframe built for static tests, and carried out 250 test flights until it was grounded in 1984 when the engine life expired.^[2]

The Il-102 was a low winged monoplane with moderately swept (30 degrees) wings and powered by two Klimov RD-33I turbofans (non-afterburning versions of the engines that power the Mikoyan MiG-29 fighter. It was highly unusual for its time in having a rear gun turret, something not seen in ground attack aircraft since the World War II Il-2 Shturmovik and Il-10, the Il-102's spiritual ancestors, controlled remotely by a gunner sitting in a cockpit above the trailing edge of the wing. The crew cockpits, engines and fuel tanks were armoured to protect against ground fire.

Although development was abandoned in 1984, the prototype Il-102 was publicly unveiled at the 1992 Mosaeroshow air show at Zhukovsky, being claimed to be available for export.^[3]
