The existence of GOR.339 was revealed to the public in December 1958 in a statement to the House of Commons. Under pressure by the recommendations of the Committee on Estimates, the Air Ministry examined ways that the various project proposals could be combined, and in January 1959 the Minister of Supply announced that the TSR-2 would be built by Vickers-Armstrongs working with English Electric; the initials coming from "Tactical Strike and Reconnaissance, Mach 2", the 'Strike' part of the designation specifically referring in RAF terminology to a nuclear weapons role.
