The United States Navy

• Foreign countries
The largest overseas base is in Yokosuka, Japan, which serves as the homeport for the Navy's largest forward-deployed fleet and is a significant base of operations in the Western Pacific. European operations revolve around facilities in Italy (Sigonella and Naples), Spain and Greece with Naples as the homeport for the Sixth Fleet and CNRE Command Naval Region Europe, which are based in Gaeta. In the Middle East, naval facilities are located almost exclusively in countries bordering the Persian Gulf, with Manama, Bahrain serving as the headquarters of U.S. Naval Forces Central Command and U.S. Fifth Fleet. Guantánamo Bay in Cuba is the oldest overseas facility and has become known in recent years as the location of a detention camp for suspected al-Qaeda operatives.
