Grumman F-9 Cougar
https://en.wikipedia.org/wiki/Grumman_F-9_Cougar
The Grumman F9F/F-9 Cougar was an aircraft carrier-based fighter aircraft for the United States Navy. Based on Grumman's earlier F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. Thrust was also increased significantly. The Navy considered the Cougar an updated version of the Panther, despite having a different official name, and thus Cougars started off from F9F-6 upward. The Navy's Bureau of Aeronautics presented requests for a testbed to study the low speed characteristic and Grumman proposed a modified Grumman F4F Wildcat with a lengthened nose and a nosewheel as well as a new swept-wing design of similar configuration but with two seats, although neither were built and the Bell L-39 (a modified Bell P-63 Kingcobra) was chosen instead. Rumors that the Soviet Union had produced a swept-wing fighter had been circulating since 1948 and the Mikoyan-Gurevich MiG-15 was widely shown at air shows in 1949. Despite the level of activity taking place with swept-wing aircraft, the Navy was initially not heavily focused on the development of such aircraft. This was largely because the Navy's focus at the time was defending the battle group against high speed and high altitude bombers with interceptors, as well as escorting medium-range carrier-based bombers in all types of weather conditions. Nonetheless the Navy appreciated the importance of getting a capable carrier-based swept-wing jet fighter. Grumman was finally awarded a contract for the development of a swept-wing fighter jet in 1951. The arrival the Mig 15, which easily outclassed straight-wing fighters in the air war over North Korea was a major contributing factor. Role Fighter aircraft National origin United States Manufacturer Grumman First flight 20 September 1951 Introduction December 1952 Retired 1974, US Navy Status Retired Primary users United States Navy United States Marine Corps Argentine Navy Number built 1,988[1] Developed from Grumman F9F Panther The first F9F-6s were assigned to fleet squadron VF-32 at the end of 1952. The First F9F Cougar squadron to actually deploy was VF-24, assigned to the USS Yorktown in August 1953 but arrived too late to the Korean theater to participate in the air war. The only version of the Cougar to see combat was the TF-9J trainer (until 1962, F9F-8T). Detachments of four Cougars served with US Marines Headquarters and Maintenance Squadron 11 (H&MS-11) at Da Nang and H&MS-13 at Chu Lai, where they were used for fast-Forward Air Control and the airborne command role, directing airstrikes against enemy positions in South Vietnam between 1966 and 1968. F9F-8s were withdrawn from front-line service in 1958–59, replaced by F11F Tigers and F8U Crusaders. The Naval Reserves used them until the mid-1960s, but none of the single-seat versions were used in the Vietnam War.
