A moored training ship (MTS) is a United States Navy nuclear powered submarine that has been converted to a training ship for Nuclear Power Training Unit (NPTU) Charleston at Naval Support Activity Charleston in South Carolina. The Navy uses decommissioned nuclear submarines and converts them to MTSs to train personnel in the operation and maintenance of submarines and their nuclear reactors. The first moored training ship was USS Sam Rayburn (SSBN-635) a James Madison-class fleet ballistic missile submarine, redesignated as (MTS-635) in 1989, followed a year later by USS Daniel Webster (SSBN-626), a Lafayette-class ballistic missile submarine, redesignated as (MTS-626). Conversion of these two boats took place at the Charleston Naval Shipyard and modifications included special mooring arrangements with a mechanism to absorb power generated by the main propulsion shaft. [1]
The Navy added two more moored training ships to this facility, USS La Jolla (SSN-701) [2] and USS San Francisco (SSN-711), [3] a pair of Los Angeles-class attack submarines. The conversions for these two took place at the Norfolk Naval Shipyard [4] and then were towed to NPTU Charleston. La Jolla became inactive in early 2015 and began the 32 month conversion to a training ship. Changes include having the hull cut into three sections, with the center section being recycled and the other two joined with three new sections, manufactured by Electric Boat, extending the overall length by 23 m (76 ft). The project was expected to be completed by the end of 2018. [5] San Francisco arrived at Norfolk to begin her conversion in January 2018. [4] La Jolla arrived at NPTU Charleston in 2019 and San Francisco arrived in 2021. [6]
With the addition of La Jolla and San Francisco, the Navy retired Sam Rayburn and Daniel Webster. [7] Sam Rayburn was towed to Norfolk Naval Shipyard in 2021 to be inactivated, and Daniel Webster will also be inactivated at Norfolk, sometime later. [8]

The Ship-Submarine Recycling Program (SRP) is the process that the United States Navy uses to dispose of decommissioned nuclear vessels. SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere.

USS La Jolla (SSN-701/MTS-701), a Los Angeles-class submarine, is named for La Jolla, California. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 10 December 1973 and her keel was laid down on 16 October 1976. She was launched on 11 August 1979 sponsored by Mrs. Jean Bryant Wilson, wife of Congressman Bob Wilson, and commissioned on 24 October 1981. In 2017, La Jolla was converted to a Moored Training Ship and is currently stationed at NPTU Charleston in Goose Creek, SC.
USS Theodore Roosevelt (SSBN-600), a George Washington-class submarine, was the second ship of the United States Navy to be named for President Theodore Roosevelt (1858–1919). Initially unnamed and assigned hull classification symbol SSGN-600 as a guided missile submarine, her keel was laid down on 20 May 1958 by the Mare Island Naval Shipyard using components initially assembled for the Skipjack-class submarine nuclear attack submarine USS Scamp (SSN-588). She was named Theodore Roosevelt and redesignated fleet ballistic missile submarine SSBN-600 on 6 November 1958, launched on 3 October 1959, sponsored by Alice Roosevelt Longworth, daughter of Theodore Roosevelt and widow of Nicholas Longworth III, and commissioned on 13 February 1961 with Commander William E. Sims commanding the Blue Crew and Commander Oliver H. Perry Jr. commanding the Gold Crew.
USS Sam Houston (SSBN-609/SSN-609), an Ethan Allen-class submarine, was the second ship of the United States Navy to be named after Sam Houston (1793–1863), president of the Republic of Texas. Sam Houston was the US Navy's seventh ballistic missile submarine.
The Lafayette class of submarine was an evolutionary development from the Ethan Allen class of fleet ballistic missile submarine, slightly larger and generally improved. This class, together with the George Washington, Ethan Allen, James Madison, and Benjamin Franklin classes, composed the "41 for Freedom," the Navy's primary contribution to the nuclear deterrent force through the late 1980s. The James Madison and Benjamin Franklin classes are combined with the Lafayettes in some references.
The James Madison class of submarine was an evolutionary development from the Lafayette class of fleet ballistic missile submarine. They were identical to the Lafayettes except for being initially designed to carry the Polaris A-3 missile instead of the earlier A-2. This class, together with the George Washington, Ethan Allen, Lafayette, and Benjamin Franklin classes, composed the "41 for Freedom" that was the Navy's primary contribution to the nuclear deterrent force through the late 1980s. This class and the Benjamin Franklin class are combined with the Lafayettes in some references.
USS Thomas Jefferson (SSBN-618), an Ethan Allen class nuclear-powered submarine, was the second ship of the United States Navy to be named for Founding Father Thomas Jefferson (1743–1826), the third President of the United States (1801–1809). She later was reclassified as an attack submarine and redesignated SSN-618.
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. In the US classification, nuclear-powered submarines are designated as SSxN, where the SS denotes submarine, x=G means that the submarine is equipped with guided missiles, x=B means that the submarine is equipped with ballistic missiles and the N means that the submarine is nuclear-powered. SSN refers to nuclear-powered attack submarines, which do not carry missiles.
USS San Francisco (SSN-711) is a Los Angeles-class nuclear submarine, the third ship or boat of the United States Navy to be named for San Francisco, California.
USS Daniel Webster (SSBN-626), a Lafayette-class ballistic missile submarine (FBM), was the only ship of the United States Navy to be named for Senator Daniel Webster.
USS Sam Rayburn (SSBN-635) was a James Madison-class fleet ballistic missile submarine named for Sam Rayburn (1882–1961), Speaker of the United States House of Representatives. Sam Rayburn was in commission 2 December 1964 to 31 July 1989 carrying the Polaris missile and later the Poseidon missile. Following decommissioning, ex-Sam Rayburn was converted into a moored training ship for use at the Naval Nuclear Power Training Unit at Goose Creek, South Carolina.
Machinist's Mate is a rating in the United States Navy's engineering community. It is non-capitalised as machinist's mate when discussing the generic rating rather than as a proper noun when discussing a specific enlisted seaman carrying that rating.
The Charleston metropolitan area is an urban area centered around Charleston, South Carolina. The U.S. Office of Management and Budget designates the area as the Charleston-North Charleston, SC Metropolitan Statistical Area, a metropolitan statistical area used for statistical purposes only by the United States Census Bureau and other federal agencies. The OMB defines the area as comprising Berkeley, Charleston and Dorchester counties, an area with 799,636 residents in the 2020 census. Principal cities include Charleston, North Charleston, and Summerville. The area is commonly referred to as the Tri-County Area or the Lowcountry, though the latter term has historically referred to South Carolina's southern coast in general.
Nuclear Power School (NPS) is a technical school operated by the U.S. Navy in Goose Creek, South Carolina as a central part of a program that trains enlisted sailors, officers, KAPL civilians and Bettis civilians for shipboard nuclear power plant operation and maintenance of surface ships and submarines in the U.S. nuclear navy. As of 2020 the United States Navy operates 98 nuclear power plants, including 71 submarines, 11 aircraft carriers, two Moored Training Ships (MTS) and two land-based training plants. NPS is the centerpiece of the training pipeline for U.S. Navy nuclear operators. It follows initial training at Nuclear Field "A" School or a college degree, and culminates with certification as a nuclear operator at one of the Navy's two Nuclear Power Training Units (NPTU).
