Launches

• R0 was launched on 28 June 1969 and was destroyed by ground control after an electrical fault led to a loss of guidance control

• R1 was launched on 4 March 1970 and was successful, although it carried no third stage payload

• R2 was launched on 2 September 1970. The first stage was successful but a leak in the HTP pressurisation system meant the rocket did not have enough velocity to reach orbit, and crashed into the Gulf of Carpentaria with the loss of the X-2 experimental satellite

• R3 was launched on 28 October 1971. The launch was completely successful and placed into orbit the Prospero X-3 satellite, making Britain the sixth nation to place a satellite into orbit.

Cancellation

The cancellation of the Black Arrow project was announced in the House of Commons on 29 July 1971 by the then Minister for Aerospace, Frederick Corfield, although permission was given for the final launch of R3 to take place after this date.

Legacy

The cancellation of Black Arrow marked the end of Britain's dreams of becoming a major space power. Britain had been at the forefront of rocketry since World War Two but swiftly fell behind during the 60s and 70s. All future British satellite launches had to rely on foreign rockets.
