Focke Wulf Fw 187

The Focke-Wulf Fw 187 Falke ("Falcon") was a German aircraft developed in the late 1930s. It was conceived by Kurt Tank as a twin-engine, high-performance fighter, but the Luftwaffe saw no role for the design, perceiving it as intermediate between the Messerschmitt Bf 109 and Bf 110. Later prototypes were adapted to two-seats to compete with the Bf 110 in the Zerstörer (heavy fighter) role, but only nine aircraft were built in total.
