caption_attribution_description: Gamma 8 rocket engine, used for the first stage of the Black Arrow launch vehicle. On display at the Science Museum, London
context_page_description: The Armstrong Siddeley, later Bristol Siddeley Gamma was a family of rocket engines used in British rocketry, including the Black Knight and Black Arrow launch vehicles. They burned kerosene fuel and hydrogen peroxide. Their construction was based on a common combustion chamber design, used either singly or in clusters of up to eight.
  They were developed by Armstrong Siddeley in Coventry, which later became Bristol Siddeley in 1959, and finally Rolls-Royce in 1966.
  Engine static testing was carried out at High Down Rocket Test Site, near The Needles on the Isle of Wight.
