This project dates back to 1943 and is part of an RAF brief for a 'super bomber' with long range, adequate defensive armament and large bomb-load. The Type 'C' as the name suggests is one of several developments by Vickers in response to this brief (there were many other design from other leading aircraft manufacturers). However, it soon became apparent that at least five years would be needed to fully develop aircraft of this complexity and versatility. Coupled with the success of the Avro Lancaster and advent of practical jet propulsion made this (and the other proposals) redundant.
