 Also in the UK in 1967 the go-ahead had been given for the UK's (separately developed) three-stage Black Arrow rocket launcher (made by Westland Aircraft, with Bristol Siddeley rocket engines developed at the Rocket Propulsion Establishment at Westcott, Buckinghamshire) - Britain did not need to rely on Europa, and Black Arrow would be ready first.Britain then withdrew from ELDO, to concentrate on the Black Arrow, but was committed to supplying ELDO with two Blue Streak rocket stages a year until 1976.At this time in 1969, Britain was spending £30 million a year on space, controlled from the Space Division of the Ministry of Technology.
