EWR VJ 101 the VJ 101C did not proceed to production status, various other projects of the era to develop supersonic-capable VTOL fighter aircraft, including the Mirage IIIV and the Hawker Siddeley P.1154 (a supersonic parallel to what would become the Hawker Siddeley Harrier, a subsonic VTOL combat aircraft that reached operational service), ultimately met similar fates. The Harrier jump jet and, substantially later, the Lockheed Martin F-35 Lightning II, has since demonstrated the potential of VTOL fighters. EWR VJ 101 The EWR VJ 101 was an experimental German jet fighter vertical takeoff/landing (VTOL) tiltjet aircraft. VJ stood for "Versuchsjäger", (German for "Experimental
Joint Combat Aircraft the UK version of the JCA would operate from the two newly ordered "Queen Elizabeth"-class aircraft carriers, the selection of the aircraft was closely linked to the design of the carrier. Candidates for the JCA were thus listed by carrier type: Following the 1998 Strategic Defence Review the Navy's Harrier FA.2s and RAF Harrier GR.7s were merged to form Joint Force 2000 (later Joint Force Harrier). As such the requirement was revised to include the replacement of the RAF Harrier force; this led to the renaming of the project as the Future Joint Combat Aircraft (FJCA) in 2001. Later, in
