The Republic F-84F Thunderstreak was an American swept-wing turbojet fighter-bomber.

In 1948, a swept wing version of the F-84 was created with the hope of bringing performance to the level of the F-86. The last production F-84E was fitted with a swept tail, a new wing with 38.5 degrees of leading edge sweep and 3.5 degrees of anhedral, and a J35-A-25 engine producing 5,300 pound-force (23.58 kN) of thrust.[1] The aircraft was designated XF-96A. It flew on 3 June 1950 with Otto P. Haas at the controls. Although the airplane was capable of 602 knots (693 mph, 1,115 km/h), the performance gain over the F-84E was considered minor.[1] Nonetheless, it was ordered into production in July 1950 as the F-84F Thunderstreak. The F-84 designation was retained because the fighter was expected to be a low-cost improvement of the straight-wing Thunderjet with over 55 percent commonality in tooling.[1]

Operational History

The Thunderstreak suffered from the same poor takeoff performance as the straight-wing Thunderjet despite having a more powerful engine. In reality, almost 700 pounds-force (3.11 kN) or ten percent of total thrust was lost because the J65 was installed at an angle and its jet pipe was not perfectly straight (in addition to the usual thrust losses from the long jet pipe). On a hot day, 7,500 feet (2,285 m) of runway were required for takeoff roll.[2] A typical takeoff speed was 160 knots (185 mph, 300 km/h).[2] Like the Thunderjet, the Thunderstreak excelled at cruise and had predictable handling characteristics within its performance envelope. Like its predecessor, it also suffered from accelerated stall pitch-up and potential resulting separation of wings from the airplane. In addition, spins in the F-84F were practically unrecoverable and ejection was the only recourse below 10,000 feet (3,000 m)

The company was established on 10 December 1939 by the armament company Oerlikon-Bührle, and construction of a new production building started in March 1940. The company was formed to do maintenance and repairs for the Swiss Air Force, the first work of the new company was assembly of EKW C-35 reconnaissance biplanes from spare parts, and overhaul work on other types
