Kfir was developed because of the embargo imposed by France after Israel bombed Lebanon in 1968, shortly after the Six-Day War.

Unable to acquire new fighter jets, the country commissioned Israel Aerospace Industries (IAI) to develop a fighter based on the Mirage 5, and from there the Nesher aircraft emerged, whose main differences were the Israeli avionics and Martin-Baker ejection seats.
Then the IAI proposed the Kfir, a fighter with greater power thanks to the replacement of the French Atar engine by the GE J79, used by the F-4 Phantom.

The Israeli fighter was also equipped with canards to improve its maneuverability in addition to having new avionics and increased armament capacity. The first Kfir flew in June 1973 and entered service in 1976 with the Israeli Air Force.
 
Vought XF8U-3 Crusader III a supersonic air superiority fighter designed to succeed the F-8 Crusader and as a competitor to the McDonnell Douglas F-4 Phantom II.

First flight of the Crusader III was June 2nd, 1958, she was designed for blazing fast speeds up to Mach 2.7 however the prototypes only ever reached Mach 2.39. A point in this aircraft's favor in competing with the F-4 was that the XF8U-3 could out maneuver the F-4 and NASA pilots routinely defeated F-4's in mock dogfights. Points in the Phantom II's favor were a much larger payload and the fact that the F-4 was also capable of the ground attack mission, the Crusader III was not. Furthermore the Phantom had a Radar Intercept Officer to guide the AIM-7 Sparrow missiles, this was often overwhelming for the single pilot of the Crusader III. Alas the XF8U-3 was not to be and sadly all 5 aircraft built were scrapped.
