The F9F Cougar was a direct and further development of the F9F Panther (detailed elsewhere on this site. The similarities between the two were limited to just the forward fuselage of the Panther being used in the Cougar design. As it stood, the Cougar became its own aircraft with the development of steadily reliable powerplants and further research into swept wing design.
The F9F Cougar came about from the Grumman company as early as 1945 - the final year of World War Two. The system was developed from the already successful straight-wing jet fighter designated as the F9F Panther. The F9F Cougar, however, was the first time Grumman had delved into swept-wing design as pioneered by the Germans throughout the war. With a contract secured, Grumman proceeded with the Cougar's development and ultimately produced a viable prototype by the early 1950's.
Finding exceptional speed and performance in this new design, the system was fitted with a very capable J48-8 engine producing over 7,000 lbs of thrust with speeds in excess of 640 miles per hour. The nimble Cougar would go into United States Navy service by the end of 1952 and see numbers reaching 662 by the end of its production run.
Armed with 2 x 20mm cannons and underwing/fuselage provisions for ordnance ranging from bombs to air-to-surface rockets, the Cougar was a light attack strike fighter and capable dogfighter that could undertake carrierbased or land-based operations. Latter versions of the Cougar would eventually be equipped with very early versions of the ultimately successful AIM-9 Sidewinder air-to-air missile systems.
In the end, the Cougar would see a successful production and service run with the United States Navy. The aircraft would be relegated to two-seat naval trainer and target drone for the new generation of pilots, though the system as a whole would be in full operational service till the middile of the 1970's. The F9F Cougar would go down as a successful platform building upon the already successful airframe of the F9F Panther and lessons learned from the Second World War and the Korean War.
