Development
Black Arrow originated from a Royal Aircraft Establishment proposal for a rocket capable of placing a 144-kilogram (320 lb) payload into low Earth orbit, in order to test systems designed for larger spacecraft. In the autumn of 1964, the programme was authorised by Conservative Aviation Minister Julian Amery; however, following a general election in October, the incoming Labour government put the project on hold to reduce expenditure.
Following another election, the government approved the continuation of the programme with several modifications, including the reduction of the test programme from five to three launches. The first launch was set for 1968.
Most of the technology and systems used on Black Arrow had already been developed or flight-proven on the Black Knight rocket, or the Blue Steel missile. Black Arrow was designed to reuse as much technology from the earlier programmes as possible in order to reduce costs, and simplify the development process. Many senior staff of the Black Knight programme transferred directly to Black Arrow, including the Chief Missile Scientist, Roy Dommett, the Chief Design Engineer, Ray Wheeler and the Deputy Chief Engineer, John Underwood.
Initial development was conducted by Saunders-Roe, which merged into Westland Aircraft in 1964. Westland was subsequently the prime contractor for the Black Arrow, and assembled the first and second stages at East Cowes on the Isle of Wight. Bristol Siddeley produced the first and second stage engines at a factory in Ansty, Warwickshire. The engines were test fired at the factory before being shipped to the Isle of Wight, where they were integrated into the rocket and the first stage engines were fired again at High Down. Bristol Aerojet produced the third stage in Somerset, while the Explosives Research and Development Establishment produced its solid propellant in Waltham Abbey, Essex. The Rocket Propulsion Establishment, based in Westcott, Buckinghamshire, was responsible for the design and integration of the stage.
The name Black Arrow came from the Ministry of Supply policy of assigning designations consisting of a colour and a noun, unofficially known as Rainbow Codes, to research programmes conducted by the Armed Forces.

Famous quotes containing the word development:
“I could not undertake to form a nucleus of an institution for the development of infant minds, where none already existed. It would be too cruel.”
—Henry David Thoreau (1817–1862)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
