Vought F4U Corsair night fighter airplane model. The Vought F4U-5N Corsair model was a single-seater night fighter variant whose main difference in outward appearance from stock F4U-5 types was the radar radome installed in the right wing. Other distinguishing features included an extra radio antenna in the vertical stabilizer, autopilot gear to reduce pilot fatigue, and extensive flash suppressor pipes and plates installed on and behind the exhaust pipe system to preserve pilot night vision. The F4U-5NL was equipped both with de-icing rubber on the leading edges of the main wings and with a water and methanol-injected de-icing system for the propeller leading edges and the canopy front windshield, design measures which pay testament to the harsh, frigid combat conditions the aircraft had to operate in during its missions over North Korea. Total production of the F4U-5N was 214 aircraft, while 101 F4U-5NL types were produced.
