THIS MODEL IS OVER 11 YRS OLD AND WAS SCRATCH BUILT BY HAROLD DOWBEKING IN 2010 AND SCALED UP TO 1/4 OFF A SET OF ZIROLI PLANS !

The Grumman F9F Panther is one of the United States Navy's first successful carrier-based jet fighters, as well as Grumman’s first jet fighter. A single-engined, straight-winged day fighter, it was armed with four 20 mm cannon and could carry a wide assortment of air-to-ground munitions.

The Panther was used extensively by the U.S. Navy and Marine Corps in the Korean War. It was also the first jet aircraft used by the Blue Angels aerobatics demonstration team, from 1949 through late 1954. The aircraft was exported to Argentina and was the first jet used by the Argentine Naval Aviation.

Total F9F production was 1,382. The design evolved into the swept wing Grumman F-9 Cougar.
Top speed: 932 km/h
Length: 11 m
Range: 2,177 km
Manufacturer: Grumman
Engine type: Jet engine
First flight: 21 November 1947

The prototype Panther, piloted by test pilot Corky Meyer, first flew on 21 November 1947. American engines available at the time included the Allison J33 and Westinghouse J34, but these were not considered sufficiently reliable, so the Navy specified the imported Rolls-Royce Nene turbojet, which was also more powerful, at 5,000 lb (2,300 kg) of thrust. Production aircraft would have a Nene, built under license by Pratt & Whitney as the J42. Since there was insufficient space within the wings and fuselage for fuel for the thirsty jet, permanently mounted wingtip fuel tanks were added, which incidentally improved the fighter's rate of roll.

The F9F was cleared for flight from aircraft carriers in September 1949. During the development phase, Grumman decided to change the Panther's engine, selecting the Pratt & Whitney J48-P-2, a license built version of the Rolls-Royce RB.44 Tay. The other engine that had been tested was the Allison J33-A-16. The armament was a quartet of 20mm guns, the Navy having already switched to this caliber (as opposed to the USAAF/USAF which continued to use 12.7mm M2/M3 guns). In addition, the Panther was soon armed with underwing air-to-ground rockets and up to 2,000 lb (910 kg) of bombs.

From 1946, a swept-wing version was considered and after concerns about the Panther's inferiority to its MiG opponents in Korea, a conversion, known as Design 93, resulted in a swept-wing derivative, the F9F Cougar, which retained the Panther's designation number.
