From the US Naval Institute:
The XF9F-1 was designed as a two-seat night fighter with four wing-mounted turbojet engines, a competitive design to the Douglas F3D Skyknight. Four powerplants were needed because of the low power available in contemporary jet engines. However, the British had developed the far more powerful Rolls-Royce Nene engine, which produced 5,000 pounds thrust and was adopted for the aircraft, now designated XF9F-2.
I thought the oval nacelles were for 2 x twin engines (like the B-45) so my guess is the Grumman XF9F-1. Sorry I don't have anything for a new challenge if I'm right so reluctantly OH.
