The work was carried out by Atlas Aviation (formerly Atlas Aircraft Corporation and lately Denel Aviation), using expertise partly gained by recruiting technicians from Israel's aborted Lavi jet fighter project.[1] The upgrade consisted of a complete refurbishment of the airframe down to zero hours (in which some 50% of the original airframe is said[who?] to have been replaced), the fitment of non-moving canards (Cheetah D & E having slightly smaller (70%) canards than that of the Cheetah C and Kfir) just aft of the engine intakes, two new stores pylons at the wing roots, an aerial refuelling probe, new ejection seats, a more powerful engine (the SNECMA Atar 9K50C-11 [upgraded in South Africa]) in the D and C variants, a new main wing spar along with a new "drooping" leading edge and a dog-tooth incision on each wing, modern elevons controlled by a twin computer flight control system, and strakes on the nose to improve the Cheetah's high-Angle of attack (AoA) performance. The aerodynamic refinements alone increased the turn rate by 15%, increased the AoA, reduced the minimum airspeed to 100 kt and increased maximum take-off weight by 700 kg. However, it also resulted in a 5% decrease in maximum level speed and acceleration. A November 1977 United Nations embargo on the delivery of weapons to South Africa forced the South African Air Force (SAAF) to place a high priority on a mid-life upgrade of the aircraft surviving from the 74 Dassault Mirage IIIs and related types received during 1963-70. The upgrade made extensive use of Israeli technology (a fact that was officially denied) and produced aircraft with similar capabilities and avionics to the Israeli Kfir. Some 16 Mirage IIIEZs were converted to Cheetah E standard, roughly equivalent to Kfir-C7, while 11 two-seater Mirage IIIDZs and D2Zs were modified as Cheetah Ds, being similar to the Kfir-TC7. Five more Cheetah Ds may have been produced from Kfir or Mirage airframes supplied by IAI.
