Submarine Force Pacific. It is the principal United States Navy submarine force operating across the vast Indo-Pacific region, headquartered at Joint Base Pearl Harbor–Hickam in Hawaii. As a major component of the United States Pacific Fleet, it provides critical capabilities in strategic deterrence, undersea warfare, and intelligence, surveillance, and reconnaissance. The force's history is deeply intertwined with pivotal conflicts like World War II and the Cold War, shaping its modern mission to maintain maritime superiority and stability.

History

The command traces its origins to the establishment of Submarine Force, U.S. Pacific Fleet in 1941, just prior to the attack on Pearl Harbor. Under leaders like Vice Admiral Charles A. Lockwood, its submarines waged a relentless commerce raiding campaign against the Imperial Japanese Navy, crippling Japanese shipping and contributing decisively to victory in the Pacific War. During the Cold War, its focus shifted to anti-submarine warfare against the Soviet Navy, with pivotal operations conducted from bases like Naval Submarine Base Bangor in Washington. The post-Cold War era saw continued operations during the War in Afghanistan and the Iraq War, with an increasing contemporary focus on strategic competition with the People's Liberation Army Navy.

Organization

The force is organized under the operational control of the United States Pacific Fleet, with its commander dual-hatted as the Commander, Submarine Force U.S. Pacific Fleet. Major subordinate commands include Commander, Submarine Group 7, headquartered at Yokosuka Naval Base in Japan, and Commander, Submarine Group 9, based at Naval Base Kitsap in Washington. These groups oversee individual submarine squadrons, which provide administrative and tactical support for their assigned boats. The force also maintains close integration with other Unified Combatant Commands, particularly United States Indo-Pacific Command and United States Strategic Command.

Fleet composition

The fleet is composed of a mix of nuclear-powered fast attack submarines and ballistic missile submarines. The primary attack submarine classes are the Los Angeles-class, Seawolf-class, and the newer Virginia-class, which conduct missions ranging from intelligence gathering to land attack. The Ohio-class submarines form the sea-based leg of the U.S. nuclear triad, with a portion configured as guided missile submarines for conventional precision strike missions. Future integration of the Columbia-class submarine will maintain the strategic deterrence mission.

Operations and deployments

Submarines routinely deploy across the Western Pacific Ocean, South China Sea, Sea of Japan, and the Arctic Ocean, operating from forward bases like Apra Harbor in Guam and Fleet Activities Yokosuka. Key ongoing operations include freedom of navigation patrols, undersea surveillance, and presence missions to ensure freedom of the seas. The force plays a central role in major regional exercises such as Rim of the Pacific Exercise and Valiant Shield, often integrating with allies like the Japan Maritime Self-Defense Force and the Royal Australian Navy.

Training and exercises

Personnel undergo rigorous training at facilities like the Naval Submarine School in Groton and the Tactical Training Group, Pacific. Submarine crews conduct intensive pre-deployment workups, including weapons system certifications and Composite Training Unit Exercise events. Advanced tactical training is provided through the Submarine Learning Center and at ranges like the Southern California Anti-Submarine Warfare Range. Joint exercises with partners, such as the multinational SEACAT exercise, enhance interoperability in anti-submarine warfare and maritime security operations.

Command and facilities

The commander's headquarters is located at Joint Base Pearl Harbor–Hickam, overseeing all administrative, operational, and logistical functions. Major support facilities include Naval Submarine Base Bangor and Naval Base Kitsap in the Pacific Northwest, which serve as homeports for ballistic and guided missile submarines. In the Western Pacific, Naval Base Guam and Yokosuka Naval Base provide critical forward maintenance and logistics hubs. The force also utilizes specialized facilities like the Intermediate Maintenance Facility in Guam and the Submarine Training Facility in San Diego.
