While having access to nuclear bombs provides an immense advantage - they are still limited by the method of delivery - which for Britain in the early 1950s was the V-bomber. Ballistic missiles provided the more effective solution, capapble of carrying nuclear warheads over vast distances, even between continents. So in 1954, Britain began the development of Blue Streak, a mid-range ballistic missile capable of launching nuclear strikes at ranges of up to 3700 km.
