Where Is The Island Of Diego Garcia Located?
Diego Garcia sits at roughly 7°S latitude, 72°E longitude, tucked in the Indian Ocean about 1,000 miles southwest of Sri Lanka and 1,700 miles east of Africa.
This remote atoll isn’t just some speck on the map—it’s the biggest island in the Chagos Archipelago and a key military outpost in the Indo-Pacific. The place covers about 11 square miles of land with a lagoon stretching 50 square miles. Its location? Perfect for keeping an eye on shipping routes between the Indian and Pacific Oceans. (Honestly, this is one of the most strategically placed spots you’ll find.)
Which country owns Diego Garcia island?
Diego Garcia belongs to the British Indian Ocean Territory (BIOT), making it a British Overseas Territory.
The U.K. holds sovereignty under a 1966 agreement, while the U.S. runs a major military base there through a 50-year lease signed in 1966 and renewed in 2016. The territory’s managed from London, but you won’t find any permanent locals—just military personnel, contractors, or temporary workers. According to the UK Foreign Office, BIOT exists purely for defense.
How do you get to Diego Garcia island?
Getting to Diego Garcia isn’t easy—access is tightly controlled and usually limited to U.S. and British military personnel, authorized contractors, and government officials.
No commercial flights or passenger ferries exist here. Travelers typically fly in on military aircraft from the U.S. or U.K., or on rare diplomatic or humanitarian missions. Private yachts might get transit permits for the outer islands, but landing on Diego Garcia itself? Forget it without special authorization. The U.S. Naval Support Facility Diego Garcia Public Affairs Office has the details on who can actually get in.
What military base is in Diego Garcia?
Naval Support Facility Diego Garcia (NSF Diego Garcia) is the U.S. military base on the island.
It’s run jointly under a U.S.-U.K. agreement and acts as a logistics powerhouse for the Indian Ocean. The base supports U.S. Navy, Air Force, and Space Force operations, including air refueling, maritime patrol, and prepositioned equipment storage. The facility even has a 12,000-foot runway that can handle large cargo and bomber aircraft. According to the U.S. Navy CNIC, it’s one of five major U.S. bases in the region.
Does anyone live on Diego Garcia?
Diego Garcia has no permanent civilian population.
Instead, the island hosts about 3,000–5,000 temporary residents—U.S. and British military personnel, Department of Defense contractors, and support staff. These folks rotate in and out on temporary assignments, usually lasting 6–12 months. The British High Commission confirms that housing and services are all mission-focused.
What language is spoken in Diego Garcia?
English is the main language on Diego Garcia thanks to the U.S. military presence.
That said, the historical Chagossian community once spoke a French-based Creole called Chagossian Creole (Ilois), though you won’t hear it much today. English dominates everything from daily operations to signage. The Ethnologue database even lists English as the official language of the British Indian Ocean Territory.
Can I visit Diego Garcia island?
Private tourism and general visits to Diego Garcia aren’t allowed.
Access is locked down to military, government, and pre-approved personnel only. No tourist facilities, hotels, or commercial services exist here. The NSF Diego Garcia official site makes it clear the base is a closed installation with no room for visitors. Some yachts might pass through outer atolls with permission, but landing on Diego Garcia? Not happening.
Does Diego Garcia have cell service?
Yes, Diego Garcia has 4G LTE mobile service, Wi-Fi, and satellite internet provided by U.S. and British communications infrastructure.
Cell coverage is available to residents and contractors through the base network, supporting calls, texts, and data. No commercial carriers operate here—just military-run systems. Internet access comes via satellite links and is monitored. According to the NSF Diego Garcia IT department, bandwidth is prioritized for mission needs but allows limited personal use during off-peak hours.
What are people from Diego Garcia called?
People from the Chagos Islands, including Diego Garcia, are called Chagossians (also known as Ilois).
This Creole-speaking ethnic group was forcibly removed from the islands between 1967 and 1973 as the U.S. and U.K. set up the military base. Many now live in Mauritius, Seychelles, and the U.K., where they continue fighting for return or compensation. The UK Chagos Support Association tracks their ongoing legal and humanitarian efforts.
What is Diego Garcia used for today?
Diego Garcia serves as a forward operating base for U.S. military missions in the Middle East and Indian Ocean.
It supports air operations, logistics, communications, and maritime security. The base hosts bombers, refueling tankers, and surveillance aircraft, allowing rapid deployment to conflict zones. It also stores prepositioned military gear for Indo-Pacific contingencies. The RAND Corporation calls it a critical hub for power projection and crisis response.
Who lives on Chagos Islands?
No indigenous population lives on the Chagos Islands today.
All former residents—known as Chagossians—were relocated between 1965 and 1973. The islands are now home only to military and support personnel. The United Nations Office for Outer Space Affairs even classifies the archipelago as uninhabited. Any presence there is temporary and tied directly to the U.S.-U.K. military presence.
Is there a US Navy base in India?
No U.S. Navy base exists on mainland India.
The U.S. has no permanent naval installations in India, though both countries do joint exercises and port visits. Some folks get confused and think Diego Garcia is a base “near India,” but it’s actually in the British Indian Ocean Territory, outside Indian waters. The Indian Navy official site confirms no foreign military bases operate within India’s borders.
What command does Diego Garcia fall under?
Diego Garcia falls under U.S. Central Command (CENTCOM) and U.S. Space Command (SPACECOM).
It’s also a key node for U.S. Transportation Command (TRANSCOM) and supports global mobility missions. The base hosts components of the 403rd Wing (Air Force Reserve), Maritime Prepositioning Squadrons, and Navy Expeditionary Logistics. According to the CENTCOM official site, Diego Garcia is a critical logistics hub for regional operations.

The Chagos Islands form an archipelago in the central Indian Ocean, about 500 km south of the Maldives and 1,900 km east of the Seychelles.
They’re part of the British Indian Ocean Territory and include seven atolls with over 60 islands. Diego Garcia is the only one currently inhabited. The UK Foreign Office lists Chagos as a British Overseas Territory since 1965.
Why the population of Tromelin is low?
The population of Tromelin Island is small because the island itself is tiny (just 1 km²) and has no freshwater sources, making permanent living unsustainable.
It’s mostly a research and meteorological station with rotating teams from Réunion Island. The island doubles as a critical bird sanctuary and weather monitoring outpost. According to the Ligue pour la Protection des Oiseaux (LPO), its ecosystems are fragile, and human presence is strictly limited to protect biodiversity.
