[edit] Design and development
The Indian Air Force (IAF) issued a requirement for a Gnat Mk 2 in 1972. Although the original requirement called for an interceptor, it was later modified to include a secondary ground-attack role. Hindustan Aeronautics Limited (HAL) modified two Gnats to act as test-bed aircraft for subsystems; these first flew in 1975, followed by the first flight of production aircraft on the 30th of September 1976. The aircraft was given the name "Ajeet", Sanskrit for "Invincible" or "Unconquered".
The changes from the original Gnat were considerable. They included:
- Improvements to the hydraulics and control systems (these had been a source of difficulties in the Gnat).
- Fitting of improved Martin-Baker GF4 ejection seats.
- Upgraded avionics.
- The addition of slab tail control surfaces.
- Improvements to the landing gear.
- Additional internal fuel capacity.
- Installation of two more underwing hardpoints.
Visually, the Ajeet appeared similar to the Gnat, with the presence of two extra hardpoints being the only obvious distinguishing features from the older aircraft.
The Ajeet entered service with the IAF in 1977 and was retired in 1991. It never saw combat.
A HAL project for a trainer based on the Ajeet was begun, leading to the initial flight of a prototype in 1982. Unfortunately this aircraft was lost in a crash later that year. A second prototype flew the following year, followed by a third. But a lack of government interest and the imminent phaseout of the aircraft meant no more examples were produced. The two surviving aircraft were sent to the only unit in the IAF operating the Ajeet, No.2 Squadron. The aircraft served with the Squadron until the phaseout of the Ajeet in 1991.
