The Republic F-84F Thunderstreak was an American swept-wing turbojet fighter-bomber. While an evolutionary development of the straight-wing F-84 Thunderjet, the F-84F was a new design. The RF-84F Thunderflash was a photo reconnaissance version.

Evolved from the straight-wing F-84, the F-84F prototype first flew in June 1950. Deliveries began in 1954, with most of the aircraft going to the Tactical Air Command as a ground support fighter bomber. Republic built 2,112 F-84Fs while General Motors fabricated 599 more. Of these, 1,301 were delivered to NATO air forces. Production of a reconnaissance version, the RF-84F, totaled 715 aircraft, including 386 for allied countries. To accommodate cameras in the nose, Republic moved the RF-84F's air intakes to the wing roots.

Through the late 1950s, the U.S. Air Force replaced its F-84Fs with supersonic F-100s, and the Thunderstreaks went to Air National Guard units. However, some F-84Fs temporarily returned to USAF service in the early 1960s due to the Berlin crisis.
