The IAR 80 was a Romanian World War II low-wing, monoplane, all-metal monocoque fighter and ground- attack aircraft. When it first flew, in 1939, it was comparable to contemporary designs such as the German Messerschmitt Bf 109B, the British Hawker Hurricane Mk.I, and the American Curtiss P-40B Tomahawk Mk.I and superior to the Dutch Fokker D.XXI and Polish PZL P.24. However, production problems and lack of available armament delayed entry of the IAR 80 into service until 1941. It remained in front-line use until 1944.
