Blue Streak missile

From Wikipedia, the free encyclopedia

The Blue Streak missile was a British ballistic missile designed in 1955. The ballistic missile programme was cancelled in 1960 but the rocket was used as the first-stage of the European satellite launcher Europa. Tested at Woomera test range, Australia, the Blue Streak project was subsequently cancelled in 1972.

[edit] Background

Post-war Britain's nuclear weapons armament was initially based on free-fall bombs delivered by the V bomber force. It soon became clear that if Britain wanted to have a credible threat a ballistic missile would be essential. There was a political need for an independent deterrent, so Britain could remain one of the major post-war powers. The use of any American missile would have appeared to hand control to the United States.

In April 1954 the Americans proposed a joint development programme for ballistic missiles. The United States would develop an ICBM of 5000 nautical mile (9,300 km) range, while the United Kingdom with United States support would develop a MRBM of 2000 nautical mile (3,700 km) range. The proposal was accepted as part of the Wilson-Sandys Agreement of August 1954 which provided for collaboration, exchange of information and mutual planning of development programs. The decision to develop was influenced by what could be learnt about missile design and development in the US. Initial requirements for the booster were made by the Royal Aircraft Establishment at Farnborough with input on the rocket engine design from the Rocket Propulsion Establishment at Westcott.

De Havilland won the contract to build the missile, and it was to be powered by an uprated liquid-fuelled Rocketdyne S3D engine, developed by Rolls-Royce, called RZ2. Subcontractors included the Sperry Gyroscope Company who produced the guidance system whilst the warhead itself was designed by the Atomic Weapons Research Establishment at Aldermaston.

However, doubts arose as the cost escalated from the first tentative figure of £50m submitted to the Treasury in early 1955, to £300m in late 1959. The programme was crawling along when compared with the speed of development in the U.S. and the Soviet Union.

[edit] Cancellation

Eventually the project was cancelled due to its apparent lack of credibility as a deterrent. Some considered the cancellation of Blue Streak to be not only a blow to British military-industrial efforts, but also to Commonwealth ally Australia, which had its own vested interest in the project.

The missiles used cryogenic propellants that could only be kept in the missile for a short length of time before icing became a problem. To fuel the rocket took 15 minutes, meaning it was incapable of being used as a rapid response to an attack. It had been intended to site the missiles in underground silos, capable of withstanding a one megaton blast at a distance of half a mile (800 m), silos originally a British innovation, later exported to the USA. These silos would have protected the missile from a first-strike attack while the missile was being fuelled. However, finding sites for these silos proved extremely difficult and RAF Spadeadam in Cumbria was the only site where construction was undertaken. The best sites for silo construction were the more stable rock strata in parts of southern England, but the construction of many large underground silos in the heart of the countryside would have carried an enormous political cost.

As no site in Britain provided enough space for actual test firing, a test site was established at Woomera, South Australia. Whitehall opposition to the project grew, and it was eventually cancelled on the ostensible grounds that it would be too vulnerable to a first-strike attack. Around £84m had been spent.

The British government transferred its hopes to the Anglo-American Skybolt missile, before the project's cancellation by the USA as its ICBM program reached maturity. The British instead purchased the Polaris system from the Americans, to be carried in British-built submarines.

After the cancellation as a military project, there was reluctance to cancel the project outright because of the huge investment that had taken place. Blue Streak would have become the first stage of a projected all British satellite launcher known as Black Prince, the second stage was derived from the Black Knight test vehicle, and the orbital injection stage was a small hydrogen peroxide/kerosene motor. This launcher never progressed beyond the design stage.

However, this too proved to be too expensive, and so the European Development Launcher Organisation - ELDO - was set up. This used Blue Streak as the first stage, but used French and German second and third stages. The Blue Streak first stage was successfully tested three times at the Woomera test range in Australia as part of the ELDO programme.

Although a total of 8 launches were made of the multi-stage vehicle, the French and German components proved unreliable leading to the project's final cancellation, and the end of Blue Streak. The final launch was made at the French site of Korou in French Guiana.

Footage from the Blue Streak launch was briefly incorporated into The Prisoner's final episode, "Fall Out". A part of the Blue Streak rocket launched on June 5, 1964 from Woomera, Australia, found 50km SE of Woomera in 1980 is on display at Giles Weather Station. Another piece was located in 2006 but its exact location has been kept secret by the finders.
