NAVAL BASE SAN DIEGO

OVERVIEW

Naval Base San Diego is the principal homeport of the United States Pacific Fleet's surface combatants and the second-largest Surface Force concentration in the U.S. Navy. Located along the eastern shore of San Diego Bay, the installation occupies roughly 1,600 acres of land and 326 acres of water and supports approximately 50 ships, including amphibious assault ships, guided-missile destroyers, and supporting auxiliaries operating across the Indo-Pacific.

The base — long known to San Diegans as the "32nd Street Naval Station" — anchors a regional Navy footprint that also includes Naval Air Station North Island across the bay, the submarine base at Point Loma, and the amphibious training facilities at Naval Amphibious Base Coronado. Together these installations make San Diego the largest concentration of U.S. naval assets on the Pacific coast and the operational center of gravity for forward-deployed U.S. surface and amphibious forces.

Naval Base San Diego hosts Naval Surface Force, U.S. Pacific Fleet — the type commander responsible for manning, training, and equipping every Pacific surface combatant — along with Expeditionary Strike Group 3, multiple destroyer squadrons, and several major training and warfare-development centers. The base also hosts a sprawling waterfront industrial complex of piers, dry docks (operated by commercial shipyards along adjacent waterfront), and intermediate-maintenance facilities that keep the Pacific Fleet ready for sea.

HISTORY

Naval Base San Diego was established in 1922 on a stretch of dredged tidal flats along the eastern edge of San Diego Bay. The Navy had operated a coaling station and small repair yard in San Diego since the early 20th century, but the explosive postwar growth of the destroyer fleet drove the service to acquire a permanent shore facility for the Pacific Fleet's smaller combatants. The new "Destroyer Base, San Diego" provided berthing, fueling, and basic maintenance for dozens of flush-decker destroyers laid up after World War I and reactivated as the international situation deteriorated through the 1930s.

The Second World War transformed the base. As Pacific Fleet operations surged after Pearl Harbor, San Diego became the principal embarkation point for warships, escorts, and supply vessels deploying to the central and western Pacific. The waterfront expanded dramatically, the original wood piers were replaced with reinforced concrete structures capable of berthing larger combatants, and the surrounding Barrio Logan neighborhood grew into a working-class community supporting the shipyard and base economy. By 1945 the installation berthed hundreds of ships and processed tens of thousands of Sailors moving to and from the Pacific theater.

Renamed U.S. Naval Station, San Diego in 1946, the installation continued to expand through the Cold War. As the Navy adopted larger and more complex surface combatants — guided-missile cruisers and destroyers, helicopter-capable frigates, and eventually amphibious assault ships — the base added longer piers, expanded fueling and weapons-handling facilities, and consolidated training and maintenance organizations along its 32nd Street waterfront. By the late 20th century, the installation had become the operational and administrative hub for the Pacific Fleet's surface forces.

The base was redesignated Naval Base San Diego in 1998 to reflect its growing administrative responsibility for surrounding Navy installations and tenant commands. Today it remains the principal homeport for U.S. Pacific Fleet surface combatants, hosting the Surface Force type commander, multiple expeditionary strike groups, several destroyer squadrons, and a network of warfare-development and training centers that support every Pacific Fleet surface ship.
