Submarine Force, U.S. Atlantic Fleet, commonly known as SUBLANT, is the principal submarine force operating in the Atlantic Ocean for the United States Navy. It is a major component of United States Fleet Forces Command, headquartered at Naval Station Norfolk in Virginia. The force provides nuclear-powered attack submarines and ballistic missile submarines for deterrence, reconnaissance, and power projection across the European Command and Northern Command areas of responsibility.

History

The command was established in January 1941, prior to U.S. entry into World War II, to consolidate submarine operations in the Atlantic Theater. During the Battle of the Atlantic, its submarines engaged German U-boats and protected vital Allied convoys to the United Kingdom and the Soviet Union. Following World War II, the force transitioned to nuclear propulsion, with the commissioning of USS Nautilus (SSN-571) in 1954 marking a new era. Throughout the Cold War, SUBLANT submarines conducted extensive intelligence, surveillance, and reconnaissance missions against the Soviet Navy, including operations near the GIUK gap and in the Mediterranean Sea. Key moments included the Cuban Missile Crisis and the development of the Polaris missile system, with USS George Washington (SSBN-598) conducting the first deterrent patrol from Naval Submarine Base Kings Bay.

Organization

SUBLANT is organized under United States Fleet Forces Command and exercises administrative control (ADCON) over all submarines, submarine squadrons, and related shore activities in the Atlantic Fleet. Its major subordinate commands include Submarine Group 2, headquartered at Naval Submarine Base New London, and Submarine Group 10, based at Naval Submarine Base Kings Bay. These groups oversee individual submarine squadrons, such as Submarine Squadron 4 and Submarine Squadron 16, which provide tactical training and readiness oversight. The command also works closely with the Naval Submarine School and the Submarine Force Library and Museum for personnel development and historical preservation.

Submarines

The force operates the United States Navy's most advanced nuclear-powered submarines. Its primary attack submarine is the Virginia-class submarine, which succeeds the Los Angeles-class submarine for missions including anti-submarine warfare and special operations forces support. The Ohio-class submarine serves in two configurations: as a ballistic missile submarine (SSBN) for nuclear deterrence patrols from Naval Submarine Base Kings Bay, and as a guided missile submarine (SSGN) for Tomahawk missile strikes. These platforms are supported by the Seawolf-class submarine for demanding open-ocean operations. Future acquisitions include the Columbia-class submarine, slated to replace the Ohio-class submarine SSBNs beginning in the 2030s.

Homeports and bases

Primary homeports are concentrated along the East Coast of the United States. The main operational base is Naval Station Norfolk, which hosts attack submarine squadrons and serves as the command's headquarters. Naval Submarine Base New London in Groton, Connecticut is the primary base for attack submarine forces in the Northeastern United States and home to the Naval Submarine School. Naval Submarine Base Kings Bay in Georgia is the exclusive East Coast base for Ohio-class submarine ballistic missile submarines. Other significant facilities include the Norfolk Naval Shipyard in Portsmouth, Virginia and the Naval Submarine Base Point Loma for forward-deployed units.

Missions and operations

Core missions encompass strategic deterrence, sea control, and power projection. Ballistic missile submarines from Naval Submarine Base Kings Bay conduct continuous nuclear deterrence patrols in the Atlantic Ocean and Arctic Ocean as part of the United States strategic nuclear triad. Attack submarines execute intelligence, surveillance, and reconnaissance against potential adversaries, support NATO exercises like Exercise Dynamic Mongoose, and provide Tomahawk missile strike capability for United States European Command. They also deploy with Carrier Strike Groups, such as the USS Gerald R. Ford Carrier Strike Group, and conduct anti-submarine warfare training with allies including the Royal Navy and Royal Norwegian Navy.

Commanders

Commanders are typically flag officers in the rank of Vice Admiral. Notable historical commanders include Vice Admiral Charles A. Lockwood, who led during World War II, and Admiral Hyman G. Rickover, the father of the nuclear navy. More recent commanders have included Vice Admiral John J. Donnelly and Vice Admiral Michael E. Connor, who later led Submarine Forces Command. The commander also serves as the Allied Submarine Commander within NATO, coordinating undersea warfare activities with partners like the United Kingdom's Royal Navy Submarine Service and the French Navy.
