Focke-Wulf Triebflügel

The Focke-Wulf Triebflügel (Triebfluegel if the ü-umlaut is not used), or Triebflügeljäger, literally meaning "thrust-wing fighter", was a German concept for an aircraft designed in 1944, during the final phase of World War II as a defence against the ever-increasing Allied bombing raids on central Germany. It was a Vertical Take-Off and Landing tailsitter interceptor design for local defense of important factories or areas which had small or no airfields.
