The Grumman F9F/F-9 Cougar was an aircraft carrier-based fighter aircraft for the United States Navy. Based on the earlier Grumman F9F Panther, the Cougar replaced the Panther's straight wing with a more modern swept wing. 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 upwards.

Prototypes were quickly produced by modifying Panthers, and the first (XF9F-6) flew on 20 September 1951. The aircraft was still subsonic, but the critical Mach number was increased from 0.79 to 0.86 at sea level and to 0.895 at 35,000 ft (10,000 m), improving performance markedly over the Panther. The Cougar would not be outclassed by Russian Mikoyan-Gurevich MiG-15s, but it was to-late to see Korean war service.

Initial production (646 airframes) was the F9F-6, delivered from mid 1952 through July 1954. Armament was four 20 mm (.79 in) M2 cannons in the nose and provision for tw-1,000 lb (454 kg) bombs or 150 US gal (570 l) drop tanks under the wings. Most were fitted with a UHF homing antenna under the nose, and some were fitted with probes for inflight refuelling. Later redesignated F-9F in 1962. Sixty were built as F9F-6P reconnaissance aircraft with cameras instead of the nose cannon.

After withdrawal from active service, many F9F-6s were used as unmanned drones for combat training, designated F9F-6K, or as drone directors, designated F9F-6D. The F9F-6K and the F9F-6D were redesignated the QF-9F and DF-9F, respectively.

F9F-7 referred to the next batch of Cougars that were given the Allison J33 engine instead of the Pratt & Whitney J48. 168 were built, but the J33 proved both less powerful and less reliable than the J48. Almost all were converted to take J48s, and were thus indistinguishable from F9F-6s. These were redesignated F-9H in 1962.

The F9F-8 was the final fighter version. It featured an 8 in (20 cm) stretch in the fuselage and modified wings with greater chord and wing area, to improve low-speed, high angle of attack flying and to give more room for fuel tanks. 601 aircraft were delivered between April 1954 and March 1957; most were given inflight refuelling probes, and late production were given the ability to carry four AIM-9 Sidewinder air-to-air missiles under the wings. Most earlier aircraft were modified to this configuration. A number were given nuclear bombing equipment. These were redesignated F-9J in 1962.

The F9F-8B aircraft were F9F-8s converted into single-seat attack-fighters, later redesignated AF-9J. 110 photo-reconnaissance versions, the F9F-8P, were also delivered in 1955-57. They were withdrawn after a short life in 1960, but some remained with reserve squadrons.

The Navy acquired 377 two-seat F9F-8T trainers between 1956 and 1960. They were used for advanced training, weapons training and carrier training, and served until 1974. They were armed with twin 20 mm (.79 in) cannon and could carry a full bombs or missiles load. In the 1962 redesignation, these were called TF-9J.[1]

Operational history

F9F-8s were withdrawn from fronto line service in 1958-59, replaced by Grumman F11F Tigers and Vought F8U Crusaders. Reserves used them until the mid-1960s, but none of the single-seat versions saw Vietnam War service.

The only version of the Cougar to see combat was the TF-9J trainer. They were used in the airborne command role, directing airstrikes against enemy positions in South Vietnam during 1966 and 1967.

The only foreign air arm to use the F9F Cougar was the Argentine Navy, wh-used the F9F Panther as well. Tw-F9F-8Ts trainers were acquired in 1962, and served until 1971. The Argentine Navy, after several failed attempts, managed to get the tw-airframes delivered by taking advantage of a bureaucracy designation mistake, but the United States refused to send spare parts during the following years. The Cougar was the first jet to break the sound barrier in Argentina.[2]
