The Cheetah was essentially a remanufactured and upgraded Dassault Mirage III.
South African airframes were used for the D and E range and Israeli airframes for the C-model. The first aircraft to be converted was a Mirage III D2Z (airframe number 845) from April 1983. It is not known publicly when its conversion was completed, but when the type was officially unveiled to the public on July 16, 1986, the type was already in service with 89 Combat Flying School, although it was only declared operational the next year.
In order to bring the airframes back to “zero hours” flown, some 50% of components were replaced. Non-moving canards were added just aft of the air intake, as were more hard points, a aerial refuelling probe, a new ejection chair and the 9K50 engine. Also fitted was a new main wingspar, a “drooping” leading edge and a dog-tooth incision on each main wing.
Improvements were also made to the avionics, radar, electronic warfare and self-protection systems, including a modern pulse Doppler radar. This is used in conjunction with a digital navigation attack system and HOTAS (hands on throttle and stick).
Ten aircraft were upgraded to fire beyond visual range missiles and two to drop laser-guided bombs. Tactical reconnaissance was limited to day operations only.
The type was phased out of general service in April 2008, well ahead of the planned date of 2012, because of cost constraints. Two remain at the Air Force Test Flight & Development Centre at AFB Overberg near Bredasdorp east of Cape Town. The others are likely in store and could be made to return to flying duty if the need arises.
