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.

Hawker Aircraft it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). Hawker Aircraft continued to produce designs under its own name as part of Hawker Siddeley Aircraft, from 1955 a division of Hawker Siddeley Group. The "Hawker" brand name was dropped, along with those of the sister companies, in 1963; the Hawker P.1127 was the last aircraft to carry the brand.
