On 11 April 1946, Grumman was awarded a contract and the US Navy gave the Grumman design the designation XF9F-1 which stood for, X=experimental, F=fighter, 9=ninth type, F=Grumman’s contractor letter designation and -1=first model. For storage on carriers, the outer wing sections folded up and the nose gear would kneel down to allow the nose to move up under the tail or wing of another aircraft.

There would be provisions for spin-stabilized rockets which would be carried internally in the nacelle fillets. It would been armed with four 20mm cannons with 250 rounds per gun to be located in the nose. It could be catapulted from carriers or take off unassisted from a clear deck. Their proposed aircraft design was a straight mid-wing, two-seat (Pilot and Radar Operator), night fighter powered by four Westinghouse 24C turbojet engines arranged in pairs under each wing. On 1 June 1945, Grumman received an outline specification for a high performance night fighter.

It was also used by the US Navy Blue Angels and the Argentine Navy. The Panther was used by the US Navy and US Marine Corps in the Korean War where the Panther provided air cover for propeller fighter bombers F4U Corsairs and AD Skyraiders. It was a single-engine, straight-winged day fighter armed with four 20mm (0.79 in) cannons and could carry rockets and bombs. The Grumman F9F Panther was one of the US Navy’s first successful carrier-based jet fighter and Grumman’s first jet fighter.
