EWR VJ-101

The EWR VJ 101 was an experimental German jet fighter vertical take-off & landing (VTOL) tilt-jet aircraft.

The VJ 101 was one of the first V/STOL designs to have the potential for eventual Mach 2 flight.

A pair of prototype aircraft, collectively known as the VJ 101 C and individually known as the X-1 and X-2, were constructed and participated in a five-year test program.

The intention was for the VJ 101 to eventually be developed as the basis for a successor for the German Air Force’s inventory of American Lockheed F-104G Starfighter interceptors.

However, development of the VJ 101 C was greatly complicated by the changing requirements of the BMVg, who decided to transform the aircraft’s envisioned mission profile from the interceptor role to a more general fighter instead, greatly changing the performance requirements for it to fulfil.

During 1968, development of the VJ 101 was ultimately cancelled.
