The Republic F-84F Thunderstreak, a turbojet fighter-bomber, was developed from the F-84  Thunderjet expecting it would have better performance than its predecessor. The F-84F featured swept-wing while the F-84 used straight-wing. Later, a variant of the F-84F was build to serve as a photo reconnaissance aircraft.

The F-84F Thunderstreak had serve with several air forces in the world outside the United States  including Belgian Air Force, Republic of China Air Force, Royal Danish Air Force, French Air Force, Luftwaffe, Hellenic Air Force, Imperial Iranian Air Force, Italian Air Force, Royal Netherlands Air Force, Royal Norwegian Air Force, Portuguese Air Force and Turkish Air Force.

The USAF Thunderbirds air demonstration squadron also flew the F-84F in 1955.

The F-84F had only very few air-to-air engagements. One of it was the shooting down of two Iraqi Il-28 Beagle by two Turkish Air Force F-84F Thunderstreaks when the Iraqi bombers crossed the Turkish border by mistake when bombing Iraqi Kurdish in August 1962.

The Design and Development of F-84F

The swept-wing version of F-84 Thunderjet was developed in 1949, designated XF-96A, and had its maiden flight on 3 June 1950. The production of F-84F Thunderstreak began in July 1950.

The United States Air Force (USAF) expected the F-84F would be a low-cost improvement of the straight-wing F-84 with over 55 percent commonality in tooling. However, in reality only 15 percent of tools could be reused.

The first production F-84F flew on 22 November 1952. The aircraft used different canopy from the test aircraft as the canopy opened up and back instead of sliding to the rear. Some problems were also found in the new design and it led to the postponement of operational flight until May 1954.

This fighter-bomber was powered by a single Wright J65-W-3 turbojet, letting the aircraft to reach a maximum speed of 695 mph (1,119 km/h) at sea level and service ceiling of 46,000 ft (14,000 m). The aircraft was equipped with A-1CM or A-4 gunsight with APG-30 or MK-18 ranging radar.

The F-84F was armed with six 0.50 in (12.7 mm) Browning M3 machine guns and could carry up to 6,000 pound (2,727 kg) of rockets and bombs, including one Mark 7 nuclear bomb.

The Variants of F-84F

  • YF-84F or YF-96 – Two swept-wing prototypes of the F-84F.
  • GRF-84F or RF-84K – A modification of RF-84F (reconnaissance version).
  • RF-84F Thunderflash – Reconnaissance version of the F-84F, 715 built.
  • XF-84H – Two F-84Fs were converted into experimental aircraft.
  • YF-84J – Two F-84Fs were converted into YF-84J prototypes with enlarged nose intakes and a deepened fuselage for the General Electric J73 engine. The project was cancelled as a result of high cost of modification of F-84F.
