During the 1960s, a number of VTOL programs were carried out by the West Germany aerospace industry. One of the most interesting was the VFW VC-400, which proposed two tilt-wing installations for VTOL flight.

Both tilt wings were located high on the fuselage, with the front wing positioned directly behind the cockpit. The rear wing was placed in front of the tail assembly. Turboprop engines were located on each wingtip - a most-interesting concept to be sure.
