After France refused to deliver Israels Mirage 5J aircraft in 1967,
it was decided to develop a version locally. Known as the Nesher
the aircraft was roughly equivalent to the Mirage 5. About 100 Neshers
were built before production switched to the more advanced Kfir.
Some Neshers were later sold to Argentina and participated in the
1982 Falklands War. The Kfir replaced the Mirage Atar turbojet with
the significantly more powerful General Electric J79. This necessitated
larger air intakes and a dorsal air scoop to cool the afterburner.
Israeli avionics were fitted in an extended nose. Early aircraft
lacked the canard foreplanes introduced on the C2 model. Some of
these early aircraft were later retro fitted to become C1. Other
improvements included in the C2 were nose strakes, dog tooth wing
leading edges and improved avionics and a HUD. Some C2 aircaft were
sold to Ecuador and Colombia while most Israeli aircraft were upgraded
to C7 standard during the 1980s. This model introduced a modern
cockpit with HOTAS controls. The type has now been largely replaced
in Israeli service and surplus aircraft are offered for export.
IAI is also offering the Kfir 2000 or C10 standard upgrade which
would see new avionics and the fitting of a multimode Elta EL/M-2032
radar. Brazil announced in September 2002 that it was negotiating
to lease 12 C10s as an interim measure pending the arrival of its
replacement fighter
