Every U.S. Navy Submarine Base in the World

Submarines are the backbone of the United States naval fleet and comprise one-third of America’s nuclear triad. The importance of submarines is supported by the idea that the US has built multiple bases around the world to maintain the readiness of its submarine fleet. While the number of bases has dropped since World War 2, multiple locations can refuel, resupply, and, if necessary, exchange crew for the US Navy.
