 During the early 1950s, the British government had identified the need to develop its own series of ballistic missiles due to advances being made in this field, particularly by the Soviet Union and the United States.A British programme to develop such a missile, named Blue Streak, was promptly initiated; however, there were key questions over the then-relatively unknown scenario of what such a vehicle would encounter when attempting re-entry to the atmosphere, there were fears that such a vehicle might simply burn up like a meteor and therefore be unachievable.Accordingly, during 1955, the Black Knight research rocket programme was commenced for this purpose.
