Ultimately, the less problematic Hawker Hunter assumed much of the intended role for the type and only half as many Swifts were manufactured as had once been intended. A later-produced photo reconnaissance variant of the Swift had resolved some of the teething problems that the type had suffered from, but this proved to be too late for it to regain favour. An advanced derivative of the Swift that was to be capable of transonic speeds, the Supermarine 545, was also under development during the early 1950s; however, in 1955, it was cancelled principally due to the poor performance of the Swift.
