In 1936, RLM issued requirements for liaison and artillery fire spotting aircraft for the Wehrmacht and Luftwaffe. This aircraft required a Short Takeoff and Landing (STOL) performance. The Fi-156 entered small scale series production in 1937. When she is in flight, the landing gear hung down. This is giving aircraft the appearance of a very long-legged, big-winged bird. The Fi156 was given a nickname - Storch (Crane).
The Storch was widely spread for Wehrmacht and Luftwaffe as air taxi for high ranking officers and generals, reconnaissance plane and air ambulance. The Storch was produced into different version, A, C and D versions. The highly successfull Storch was exported to German allies - Croatia, Finland, Sweden, Bulgaria, Slovakia, Romania and Italy. After WWII, the Storch continued frontline service in different countries.
