In 1955 the Intermediate Range Ballistic Missile Test Centre was built for the Blue Streak missile project. The RAF took it over in 1976 and it became Europe's first Electronic Warfare Tactics Range in 1977. The range contains ground-based electronics warfare equipment to act as a simulated threat to training aircrews. Some of the equipment was manufactured in the Soviet Union; some simulated emissions from potential enemy systems. It also has real and dummy targets such as airfields, a "village" of portable buildings, tanks, aircraft and vehicle convoys.
