Sukhoi T-4, or "Aircraft 100", or "Project 100", or "Sotka", or Su-100 was a Soviet high speed reconnaissance, anti-ship and strategic bomber aircraft. Despite design similarities, the Sukhoi T-4 was not intended as a Soviet equivalent of the North American XB-70 Valkyrie supersonic bomber, but was rather intended to take advantage of many of the XB-70's aeronautic innovations to develop a smaller reconnaissance and anti-carrier aircraft capable of reaching Mach 3.
Delivered from Vickers Weybridge in August 1956. Latterly served 214 Squadron, the fin markings of which squadron it bears. Exhibited at the RAF 50th anniversary show wearing the white anti-nuclear flash scheme. - Photo taken at Abingdon (ABB) in England, United Kingdom on June 15, 1968.
