COMSUBPAC, Pearl Harbor

Commander, Submarine Force, U.S. Pacific Fleet (COMSUBPAC), headquartered at Pearl Harbor, Hawaii, was established in 1941 to oversee all U.S. Navy submarine operations in the Pacific. During World War II, COMSUBPAC coordinated submarine patrols that played a decisive role in disrupting Japanese maritime supply lines, significantly contributing to Allied victory. In the Cold War era, the command adapted to new strategic priorities, overseeing the deployment of nuclear-powered submarines and ballistic missile submarines as part of the nation’s nuclear deterrent. Today, COMSUBPAC continues to provide operational control, training, and support for Pacific Fleet submarines, ensuring undersea superiority in the Indo-Pacific region.
