Of the three jet bombers that formed the RAFs V-Force in the early years of the Cold War (1946-1991) the Victor was perhaps the most technologically advanced. First flown on December 24 1952 the Victor entered service in B 1 configuration in November 1957. Further improvements were introduced with the B 2 which was optimized for high altitude. Most B 2s were equipped to carry the Blue Steel st&-off missile but eight were modified in the strategic reconnaissance role because the Victor 2 was then the longest-ranging aircraft in the RAF. The Victor ceased to be a low-level bomber after the nuclear mission was taken over by the Royal Navys Polaris submarine force in the late 1960s. Thereafter Victor 1s & 2s continued in frontline service as airborne tankers supporting operations such as the Falklands War & the Gulf War until the last Victor flight took place on November 30 1993.
