Cold War Cumbria As well as being the production facility (at Sellafield) for Britain's plutonium for the 1950's Cold War, Cumbria also was home to Britain's foray into developing a missile to carry such nuclear hell to its destination. In the 1950s British high tech industry was gearing up to production of an intermdiate range ballistic missile, Blue Streak. On Spadeadam Moor, Cumbria were completed in under three years at a cost of £20 million. Over 8,000 acres Spadeadam had its own admin area dn liquid oxygen plant and static missile testing areas before the completed missiles were sent to Woomera in Australia for testing. Housing was specifically built for the highly trained staff at nearby Brampton. In 1960 Blue Streak was cancelled.
