Israel developed the Kfir after the French refused to deliver 50 paid for Mirage VJs. This is the prototype for the Kfir that first flew on 19 October 1970. It's a Mirage IIIBJ with a General Electric J-79 (Phantom) engine.

The IAF purchased four Mirage IIIBJs for operational training on the Mirage. They even served in combat and shot down several enemy aircraft. In the late 1960s this aircraft was transferred to Israel Aircraft Industries as an experimental aircraft. The other three IIIBJs were sold to Argentina.
