Navy Support Facility Diego Garcia at a glance
Navy Support Facility Diego Garcia supplies logistical and installation support to U.S. and allied forces in the Indian Ocean. Its official mission describes support that can reach across several geographic command areas, reflecting the island's role in a wider chain of overseas sustainment. The facility supports different mission requirements rather than a single publicly defined ship or aircraft unit.
The U.S. support presence followed a 1966 agreement with the United Kingdom, with Navy Seabees beginning construction in 1971. A major construction program reached completion in 1986. The facility's remote island setting makes official command resources especially important for understanding an assignment. Researching Diego Garcia therefore brings together the history of its construction and the logistical and community services that sustain personnel at an isolated overseas location.
