The Vickers-Armstrongs V-1000 was a proposed jet-powered cargo aircraft that was designed to meet a requirement issued by the British Ministry of Supply which sought a strategic transport for the Royal Air Force (RAF) to support its strategic bomber fleet, particularly the V-bombers. The design bears many similarities to the Vickers Valiant, one of the V-bombers, but also featured substantial changes. In addition to its military application, both the Ministry and Vickers also intended to use the same basic design as the VC7, a six-abreast trans-Atlantic jet airliner for British Overseas Airways Corporation (BOAC).
