The Fieseler Fi 157 was an unsuccessful attempt at developing a radio-controlled, full-sized anti-aircraft target.
In 1937, the Reichsluftfahrtministerium (RLM) contracted Fieseler to produce a radio controlled anti-aircraft target drone. The resulting Fi 157 was a low-wing monoplane of entirely wooden construction and was carried beneath a bomber before being released. All three prototypes crashed during testing; a single example of a manned version, designated Fi 158, was built to investigate remote guidance.
