Naval Submarine base Pearl Harbor

Naval Submarine Base Pearl Harbor was officially established in 1917 on the island of Oahu, Hawaii, to support the growing role of submarines in U.S. naval strategy. During World War II, the base became a vital hub for submarine operations in the Pacific, serving as a homeport, repair, and resupply center for submarines conducting patrols against Japanese shipping. Submarines operating from Pearl Harbor played a decisive role in cutting off enemy supply lines and gathering intelligence. Today, the base is part of Joint Base Pearl Harbor-Hickam and continues to support the U.S. Navy’s Pacific Fleet submarine force, maintaining its legacy as a cornerstone of undersea warfare.
