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.

Yokosuka Submarine Base

Naval Submarine Base Pearl Harbor

• Years operational: 1918 – present

One of the best-known naval stations for US forces, Naval Submarine Base Pearl Harbor was first formed at the end of World War I. Since then, it’s been one of the most critical naval stations, supporting 15,644 torpedo loads during World War II.
