One major U.S. Navy installation is catalogued in British Indian Ocean Territory: Naval Support Facility Diego Garcia.

Operated jointly with the United Kingdom under the 1966 U.S.–U.K. Exchange of Notes (50-year agreement, extended in 2016 for an additional 20 years through December 2036). The U.K. retains sovereignty; U.S. forces operate as tenants of British Indian Ocean Territory. See each base's host-nation context for installation-specific arrangements.
