The origin of the Republic's swept wing F-84 variants can be traced back to 1944, when the USAAF proposed converting the P-47 Thunderbolt into a jet by installing two General Electric TG-180 axial flow turbojets in its fuselage.

The F-84 was the first single seat fighter capable of carrying a nuclear weapon. The swept-wing F-84F evolved from the straight-wing F-84, and the prototype first flew on 3 June 1950. This variant became operational in 1954. Its Wright J65 jet engine gave it a cruise speed of 535 mph and a maximum speed of 720 mph.
