The IAR 37 was a 1930s Romanian reconnaissance or light bomber aircraft built by Industria Aeronautică Română. DevelopmentThe IAR 37 prototype was flown for the first time in 1937 to meet a requirement for a tactical bombing and reconnaissance aircraft. The IAR 37 was an unequal-span single bay biplane with a fixed tailwheel landing gear and powered by a licensed copy of the Gnome-Rhône Mistral Major radial engine called the IAR K14-II C32 with 870 HP. It had room for a crew of three under a continuous glazed cockpit, pilot at the front then observer and a gunner at the rear. It had dual controls and was fitted with a locally designed bombsight and a camera. The IAR 37 entered production in 1938, but production of the engine lagged, preventing the aircraft from being completed,and it was replaced on the production line by the IAR 38, powered by the reliable BMW 132 engine. As availability and reliability of the K.14 engine improved, the incomplete IAR 37s were fitted with IAR K.14-III C36 with 930 HP to allow their completion and production was switched to the improved IAR 39, which also used the IAR K.14-IV C32 with 960HP. Total production of all three types was 380, at both IAR and SET, continuing until October 1944 with the majority being IAR 39s.[1] Operational historyThe aircraft entered service with the Royal Romanian Air Force in 1938 and, by the end of the 1940, they equipped a large number of squadrons. When Romania supported the German offensive against the Soviet Union 15 of the 18 reconnaissance squadrons were equipped with IAR biplanes. The IAR 39 was used by most of the reconnaissance squadrons involved in the 1941 offensive against the Soviet Union. When the new post-war government was formed in 1947, a smaller number of IAR 39s were used by the new Romanian Air Force for training and liaison.[2] Variants
