Design/Development

n early 1968, the Soviet Ministry of Defence decided to develop a specialised shturmovik armoured assault aircraft in order to provide close air support for the Soviet Ground Forces. The idea of creating a ground-support aircraft came about after analysing the experience of ground-attack (shturmovaya) aviation during the 1940s, 1950s, and 1960s.[2] The Soviet fighter-bombers in service or under development at the time (Su-7, Su-17, MiG-21 and MiG-23) did not meet the requirements for close air support of the army.[2] They lacked essential armour plating to protect the pilot and vital equipment from ground fire and missile hits, and their high flight speeds made it difficult for the pilot to maintain visual contact with a target. Having taken into account these problems, Pavel Sukhoi and a group of leading specialists in the Sukhoi Design Bureau started preliminary design work in a comparatively short period of time, with the assistance of leading institutes of the Ministry of the Aviation Industry and the Ministry of Defence.[3]

In March 1969, a competition was announced by the Soviet Air Force that called for designs for a new battlefield close-support aircraft. Participants in the competition were the Sukhoi design bureau and the design bureaus of Yakovlev, Ilyushin and Mikoyan.[4] Sukhoi finalised its "T-8" design in late 1968, and began in work on the first two prototypes (T8-1 and T8-2) in January 1972. The T8-1, the first airframe to be assembled, was completed on 9 May 1974. Another source says November 1974. However, it did not make its first flight until 22 February 1975, after a long series of test flights by Vladimir Ilyushin. The Su-25 surpassed its main competitor in the Soviet Air Force competition, the Ilyushin Il-102, and series production was announced by the Ministry of Defence

The type has seen combat in several conflicts during its more than 30 years in service. It was heavily involved in the Soviet–Afghan War, flying counter-insurgency missions against the Mujahideen. The Iraqi Air Force employed Su-25s against Iran during the 1980–88 Iran–Iraq War. Most were later destroyed or flown to Iran in the 1991 Persian Gulf War. The Georgian Air Force used Su-25s during the Abkhazia War from 1992 to 1993. The Macedonian Air Force used Su-25s against Albanian insurgents in the 2001 Macedonia conflict and, in 2008, Georgia and Russia both used Su-25s in the Russo-Georgian War. African states, including the Ivory Coast, Chad, and Sudan have used the Su-25 in local insurgencies and civil wars.
