Overseas military bases of the United Kingdom


Overseas military bases of the United Kingdom enable the British Armed Forces to conduct expeditionary warfare. Bases tend to be located in or near areas of strategic or diplomatic importance, often used for the build-up or resupply of military forces, as was seen during the 1982 Falklands War and the use of RAF Ascension Island as a staging post. Most of the bases are located on British Overseas Territories or former colonies which retain close diplomatic ties with the UK.
In total, the UK has 16 overseas military bases, second only to the United States. They often have been used by its allies, predominantly the US. A number of military operations would not have been possible without the strategic island of Diego Garcia in British Indian Ocean Territory. It was used for major operations during the War on Terror, Operation Granby, Operation Herrick, Operation Telic, Operation Shader, Operation Desert Storm, Operation Desert Fox, Operation Enduring Freedom, Operation Iraqi Freedom, and Operation Inherent Resolve.
