History
In 1971, the local population of Diego Garcia, the Chagossians, was forcibly expelled from the island to make way for the base.

The Navy tasked the Seabees of Naval Mobile Construction Battalions 1, 40, 62, 71, 133 and Amphibious Construction Battalion 2 with the construction of the base. On 23 January 1971 the first men of NMCB 40 arrived on site to begin what became an extended project. Naval Support Facility Diego Garcia, was established as the senior United States Navy command on the island on 1 October 1977. At the time the NAVCOMMSTA was the primary tenant, but as new major facilities were completed, most notably the expanded anchorage and mooring area and the extended airfield, other tenants were commissioned. In 1980, the United States Navy established the Near-Term Prepositioned Force of 16 ships. Then NTPF became the Afloat Prepositioning Force (AFP) and eventually Maritime Prepositioning Ship Squadron Two (MPSRON 2) consisting of 20 deep-water pre-positioned logistics ships anchored in the lagoon.

In 1981, the naval air facility was commissioned. It was decommissioned in 1987 and its responsibilities returned to the Naval Support Facility Diego Garcia.

In 1982, construction activities were transferred from the Seabees to a consortium of civilian contractors, Raymond International, and Brown and Root and Molem, a joint venture. Raymond had deep-draft wharf and waterfront skills, Brown and Root had concrete and infrastructure skills, and Molem was an English firm known for taking on challenging projects. The majority of the projects were completed by 1988.

On 26 March 1982, Barbara Shuping and five other women were assigned to the Naval Support Facility Diego Garcia. They were the first women to live on the island since the Chagossians were expelled in 1971.

In 1985, the new port facilities were completed and the USS Saratoga (CV-60) was the first aircraft carrier to tie up.

The Strategic Air Command began deploying Boeing B-52 Stratofortress bombers and aerial refueling aircraft to the newly completed airfield facilities in 1987.

Following the Iraqi invasion of Kuwait in August 1990, three ships of COMPSRON 2 sortied, delivering a Marine Expeditionary Brigade to Saudi Arabia for participation in the Gulf War. Other COMPSRON 2 ships offloaded the ammunition and fuel on Diego Garcia that were required for the American bomber fleet that deployed to the airfield. Subsequently, B-52G bombers flew more than 200 17-hour bombing missions over 44 days and dropped more than 800,000 ST of bombs on the Iraqi Armed Forces in Iraq and Kuwait. One of the B-52s crashed from mechanical failures just north of the island with the loss of three of its six-man crew.

Beginning on 7 October 2001, the United States again commenced military operations from Diego Garcia using B-1, B-2, and B-52 bombers to attack Taliban and al-Qaeda targets in Afghanistan following the September 11 attacks on the World Trade Center and the Pentagon. The base played an important role in the invasion of Afghanistan until the U.S.-led coalition could establish forward bases in the country because many countries closer to Afghanistan such as Turkey, Pakistan, and Saudi Arabia refused to allow United States air bases in their territory to be used for combat operations. On 12 December 2001, a B-1 bomber was lost to mechanical failures just after takeoff from the island, but the crew survived and was rescued by the USS Russell (DDG-59). Four B-2 Shelter System Extra Large Deployable Aircraft Hangar Systems were erected at Diego Garcia to support the bombers' operations. Combat operations resumed in the spring of 2003, with MPSRON 2 sortieing to the Persian Gulf for the Iraq War, and bombing operations began again, this time against Iraq. Bomber operations ceased from Diego Garcia on 15 August 2006.
