Naval Submarine base Pearl Harbor

• Early Establishment: Naval Submarine Base Pearl Harbor was officially established in 1917, making it one of the oldest submarine bases in the United States Navy. • Strategic Pacific Location: The base's position in the Hawaiian Islands provides the U.S. Navy with a vital strategic hub for submarine operations throughout the Pacific Ocean. • Pearl Harbor Attack: On December 7, 1941, the base and its submarines were present during the Japanese attack on Pearl Harbor. Submarines stationed there played a crucial role in the U.S. response to the attack. • USS Bowfin: The USS Bowfin (SS-287), now a museum ship at Pearl Harbor, completed nine successful war patrols from the base during World War II, earning the nickname "Pearl Harbor Avenger." • Rapid WWII Expansion: During World War II, the base expanded rapidly, supporting as many as 60 submarines and thousands of personnel, making it a major center for Pacific submarine operations. • Submarine Success: Submarines operating out of Pearl Harbor were responsible for sinking over half of all Japanese merchant ships destroyed during WWII. • Evolution to Nuclear Power: The base adapted in the 1950s and 1960s to support the new fleet of nuclear-powered submarines, becoming a forward base for Cold War deterrence missions. • Submarine School Training: The base has hosted advanced training and simulators for submarine crews, including escape training in the Submarine Escape Training Tank (SETT). • Modern Role: Today, the base is home to Submarine Squadron One and Submarine Squadron Seven, supporting both Los Angeles-class and Virginia-class fast attack submarines. • Memorials and Museums: The base is adjacent to the Pearl Harbor National Memorial, and the USS Bowfin Submarine Museum & Park attracts thousands of visitors annually, honoring the legacy of submariners.
