context_page_description: 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 being deployed by the airforces of the most advanced military powers such as the Hawker Hurricane and Bf 109E. Production problems and lack of available armament delayed entry of the IAR 80 into service until 1941. It remained in frontline use until May 1945.
context_section_description: IAR realized that the Mistral Major was at the limits of its development potential even by the middle of 1941, when the 1000A model reached the same ultimate output as the original Gnome-Rhône versions. An ongoing program to fit the IAR 80 with a more powerful engine had been in the works for most of the design's lifetime, but this proved to be a fruitless endeavor.
  The most obvious choice for a new engine would have been the BMW 801 used in the Focke-Wulf Fw 190. This engine produced a full 600 hp (450 kW) more power, and although it was heavier, it was of roughly the same size as the K14. IAR engineers estimated that a BMW powered IAR 80 would have a maximum speed of at least 600 km/h (370 mph). But, as always, the Germans were unable to supply the engine as every example coming off the line was needed for installation in a German airframe. Licensed production was likewise out of the question, the engine production was in the midst of being ramped and the demand was so great that not even one set of jigs could be spared.
  A Junkers Jumo 211 was trialled, and although this engine was also in high demand in Germany in this case the SM.79JRs in FARR service already used the engine, so some were available for testing. One 1,220 hp (910 kW) 211Da was obtained, complete with cowling and ring radiator from an SM.79 and fitted to an IAR 80 in 1942. Development was abandoned after the first test flight when in-flight vibrations proved to be excessive, and was never flown again.
  After World War II, the Soviets shipped home the entire I.A.R. factory and all aircraft from Braşov, as war reparations.
