MOD Hebrides is a Ministry of Defence site located in the Outer Hebrides, Scotland, operated by QinetiQ and controlled by the Royal Air Force. It functions as a deep-sea range for complex weapons trials and an inner range for ground-based air defence test and evaluation. The site was built in 1957–58 by RAF 5004 Airfield Construction Squadron, primarily for testing the MGM-5 Corporal missile, Britain's first guided nuclear weapon, despite local protests. During the Cold War, missiles were fired toward target coordinates in the Atlantic Ocean, with radar on Hirta (St Kilda archipelago) identifying landing points. The range also tested MGM-29 Sergeant and MGM-52 Lance tactical nuclear missiles, as well as high-altitude research rockets like Skua and Petrel. It was previously operated by the Defence Evaluation and Research Agency (DERA). Currently, it serves as a testing facility for missile systems such as the Rapier missile and unmanned aerial vehicles. In 2016, a £180 million investment was announced for modernizing its facilities. In 2023, it hosted Exercise Formidable Shield, a NATO ballistic missile defence exercise involving over 4,000 personnel, 20 ships, 35 aircraft (including Eurofighter Typhoon and F-35 Lightning II), and eight ground units. In 2024, the DragonFire laser directed-energy weapon was tested at the range. The facilities include a Tracking Radar Facility, Telemetry for data monitoring, and support services. The range occupies 115,000 km² of sanitized airspace with unlimited altitude, with missile tracking conducted from St Kilda, which is leased by the Ministry of Defence.
