Black Arrow
From Wikipedia, the free encyclopedia
A Black Arrow rocket launches the Prospero X-3 satellite. The relatively pale exhaust results from the use of hydrogen peroxide as the oxidiser. |

This article is about the rocket, for the novel, see The Black Arrow
Black Arrow was a British satellite carrier rocket, based on the Black Knight and Blue Streak rockets. Black Arrow was the brainchild of British engineer John Scott-Scott. It was developed by the Royal Aircraft Establishment and built by Saunders-Roe on the Isle of Wight. Its engines were tested at The Needles[1] before being launched at Woomera in Australia.
The rocket used hydrogen peroxide oxidizer with kerosene fuel.

[edit] 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
- 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 the United Kingdom the sixth nation to place a satellite into orbit (See Timeline of first orbital launches by nationality).
[edit] 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. The last vehicle, R4, was never launched, and may be seen on display at the Science Museum, London.
The decision was taken on grounds of cost effectiveness; it was decided that using NASA's solid fuel Scout rocket for future launches would offer adequate performance at a lower cost.
[edit] Legacy
The cancellation of Black Arrow marked the end of the UK's chances of becoming a major space power. The UK had been at the forefront of rocketry since World War II but swiftly fell behind during the 60s and 70s. All future British satellite launches had to rely on foreign rockets.
As of 2006, the UK is the only nation to have successfully developed and then abandoned a satellite launch capability.[citation needed]

The Black Arrow was also an arrow used by Bard the Bowman in his attempt to slay Smaug. It is hinted in the book that it has been passed through generation. Bard also says that it has never missed it's mark, and that it had always come back to him, wherever he shot it.
