Regional Support GroupRegional Support Group (RSG) Groton is Command U.S. Submarine Force Atlantic’s direct waterfront representative. RSG directs, assigns and monitors the accomplishment of maintenance on all assigned submarines. This involves long-range planning, coordination of repair activities and monitoring the execution of work in progress.
Naval Submarine Support FacilityNaval Submarine Support Facility (NSSF) New London was established in February 1974. Organized and staffed along the lines of an afloat submarine tender Intermediate Maintenance Activity (IMA), the command employs more than 400 military members, 42 DOD civilians and 297 contractors.
The primary mission of NSSF is to provide direct maintenance support to submarines assigned to Submarine Squadron 4 and Submarine Development Squadron 12. Visiting ships are often supported.
NSSF is divided into eight departments: Repair, Weapons, Administration, Safety, Facilities Support Group, Supply, Comptroller and Information Resource Management. The Repair Department is the largest, accounting for more than 500 positions that encompass approximately 35 repair shops. The capabilities of the Repair Department cover the full spectrum of maintenance operations required by modern submarines.
The Weapons Department stores, tests and issues all tactical weapons, pyrotechnics and ordnance loaded aboard New London area submarines. The weapons handled include the Mark 48 ADCAP torpedo, the Tomahawk cruise missile, external countermeasures and ammunition. The highly sophisticated Mark 48 ADCAP torpedo is the primary tactical weapon for the submarine force. The Weapons Department also maintains and operates an armory for small-arms storage and provides training for all local area commands through use of its small-arms range.
The other six departments combine to provide the necessary support required by the command and the Groton waterfront. There are more than 100 people — military and civilian — employed in these departments.

Supervisor of ShipbuildingElectric Boat, located in Groton, Connecticut, has more than a century of experience building submarines, beginning in 1899 with a 54-foot submersible vessel developed by John Philip Holland. During World War I and just after, Electric Boat received orders to build 85 submarines for the U.S. Navy.
Since that time, Electric Boat has continued building submarines for the Navy to include its nuclear fleet of Los Angeles-, Seawolf- and now Virginia-class submarines — some of which are currently stationed at Naval Submarine Base New London.
The Office of the Supervisor of Shipbuilding is the liaison between the Department of the Navy and the Electric Boat. It is the supervisor’s responsibility to administer all contracts, provide government-furnished equipment and outfit ships, assure that the requirements of the contracts are fully met, ascertain that satisfactory production progress is maintained and ensure that the fleet is provided quality warships, fully prepared to sail “in harm’s way.” The supervisor’s office has been recognized by the secretary of the Navy with the award of a Meritorious Unit Commendation in 1981, 1985, 1989 and 2006.
The history of the Supervisor of Shipbuilding, Conversion and Repair, U.S. Navy — better known as SUPSHIP, Groton — dates back
to 1931. That year, the U.S. Navy and the Electric Boat began negotiations for the construction of USS Cuttlefish (SS 171) at Groton. As a result, the Office of the Superintending Constructor was established July 11, 1931. Shortly thereafter, on Aug. 1, 1931, the Office of Inspector of Machinery was established. Its responsibility covered the inspection of construction, machinery and materials. Under the joint direction of these two offices, the keel of the Cuttlefish was laid Oct. 7, 1931. The boat was delivered June 8, 1934.
The Office of Superintending Constructor and the Office of the Inspector of Machinery continued until May 11, 1940, at which time their efforts were consolidated into one office — the Supervisor of Shipbuilding, U.S. Navy.
Since the delivery of Cuttlefish in 1934, hundreds of ships have been delivered by the General Dynamics Corp., Electric Boat Division, under the supervision of this command. Notably included was the first nuclear-powered submarine, USS Nautilus (SSN 571), commissioned in 1954; the first Polaris fleet ballistic missile submarine, USS George Washington (SSBN 598), commissioned in 1959; the first Trident fleet ballistic missile submarine, USS Ohio (SSBN 726), commissioned in 1981; the first Seawolf-class attack submarine, USS Seawolf (SSN 21), commissioned in 1997; and the first Virginia-class attack submarine, USS Virginia (SSN 774), commissioned in 2004.
Today, with the completion of Los Angeles-class, Ohio-class and Seawolf-class submarines, the command is focused on Virginia-class construction programs awarded by the Naval Sea Systems Command. In 2006, the Navy also awarded Electric Boat a $13.7 million contract modification for nuclear submarine work. Currently, Electric Boat employs 10,500 people between its Groton, Connecticut, and Quonset Point, Rhode Island, facilities. The latter facility was established in 1974.
Submarine Learning Center (SLC)The Submarine Learning Center (SLC) is an integral part of the Navy’s Revolution in Training, as implemented by Task Force EXCEL (Excellence through Commitment to Education and Learning). It is one of 14 specialized learning centers whose primary function is to partner with fleet representatives in defining individual human-performance solutions to meet Submarine Force performance requirements. Additionally, the SLC will create, coordinate and execute the future training and education vision for the Submarine Force.
The revolution in Navy training presents unlimited opportunities for the Submarine Force to continue to improve upon its unmatched record of training excellence. Through the infusion of training technology innovation, re-engineering of learning methods and the commitment to ensure our Sailors remain the central element in performance solutions, the SLC will lead our six submarine learning sites in ensuring our undersea warriors are fully prepared to fight and win in the 21st century.
Naval Submarine SchoolWhen the first class of 24 officers began studies for submarine duty in the summer of 1916, the submarine base in Groton, Connecticut, was little more than a handful of buildings scattered across the area now known as lower base.
By Christmas 1916, the 22 graduates of the first submarine officers’ course were heading out for assignments after spending six months training on submarines, torpedoes, engineering and electricity. Records are sketchy on the nature of much of that training, especially since the bulk of the early trainers were salvage material from decommissioned submarines. Within a year, the submarine officers, and those who followed them through Naval Submarine School, were serving around the globe when the United States entered World War I.
Nearly 100 years after that first graduation, the Naval Submarine School, the submarine base, the U.S. Navy and the world have all undergone radical and profound change, but the tradition as the center for submarine training excellence continues.
From one building on lower base in 1916, Naval Submarine School has grown to the largest single tenant unit on SUBASE, with nearly 40,000 Sailors graduating annually from nearly 200 different courses. From an era when training aids were Mark I Attack trainers and a German-built trainer of unspecified history, Naval Submarine School maintains and operates state-of-the-art trainers costing millions to design and develop. These trainers are vital tools in providing realistic individual and team training for the submarine fleet.
Naval Submarine School course offerings include introduction, apprentice and basic skill level training; encompass initial technical proficiency training and advanced team operator and team training in electronic and combat systems employment, navigation and damage control; and provide mid-career professional growth courses for both officers and enlisted Sailors.
Naval Submarine School also conducts refresher training of all Atlantic Fleet submarines completing construction or overhaul and pre-deployment and training ashore for all submarines of the Atlantic Fleet.
No one can forecast the future. But Naval Submarine School can look to our history with confidence that we will continue to serve the Navy and the nation with pride in our past and a continued commitment to excellence in the future.
