The Focke Wulf Fw 159 was an experimental German fighter of the 1930s, designed by Kurt Tank which never reached production, as it was considered inferior to the He 112 and Bf 109.

It was a heavier variant of the Focke-Wulf Fw 56, with several improvements, such as a retractable landing gear and enclosed cockpit.

Its parasol wing configuration was based on the company's successful trainer product, the Focke-Wulf Fw 56 Stösser, and it used a Junkers Jumo 210 engine.

The plane had an enclosed cockpit and a rearward-retracting lever-action suspension main undercarriage which retracted completely into the lower fuselage.

The first prototype, the Fw-159 V1, was ready in the spring of 1935 but was destroyed when it crash-landed following the failure of the main undercarriage to deploy properly.
