Diego Garcia
The Strategic Value of a Remote Military Outpost
Diego Garcia is a V-shaped atoll in the Chagos Archipelago, located roughly 3,200 km south of India's southern tip in the central Indian Ocean. It hosts one of the United States' most important military installations outside the continental US — Naval Support Facility Diego Garcia — jointly operated with the United Kingdom. The base provides power-projection capability across the Middle East, East Africa, and Southeast Asia simultaneously. Its runways accommodate B-52 strategic bombers, B-2 stealth bombers, KC-135 refueling tankers, P-8 maritime patrol aircraft, and heavy transport aircraft. A deep-water harbor can dock nuclear submarines and surface combatants. Its extreme remoteness (previously ~3,900 km from Iran's coast) was considered a strategic advantage — until March 2026.
