As the British were a few years ahead of the US in jet engine development, the Grumman design team decided to import a single Rolls-Royce “Nene” for installation in the XF9F-2 prototype. At the same time, Pratt & Whitney was licensed by Rolls-Royce to manufacture the Nene which was a turbojet of 5,700 lbs (22.24 kN) maximum thrust.
The first Nene powered XF9F-2 flew on Thanksgiving Day, 1947. It was a very sleek looking craft with elevators sitting high on a tail that jutted out past the tail pipe of the J-42 Nene. Air was scooped to the engine through triangular openings at the wing roots. It could reach 20,000 ft. (6,096 m) in just over two and a half minutes and zip along at 573 mph (922.16 kph) at that altitude. Top speed was just under 600 mph (965.61 kph) at sea level.
