recycling. † A dagger after a completion date indicates that portions of the hull were preserved as memorials. See the individual articles for details. Because the program is underway, this list is almost certainly incomplete. Note for ships marked with refit: Sam Rayburn (SSBN-635) was converted into a training platform – Moored Training Ship (MTS-635). Sam Rayburn arrived for conversion on 1 February 1986, and on 29 July 1989 the first moored training ship achieved initial criticality. Modifications included special mooring arrangements including a mechanism to absorb power generated by the main propulsion shaft. Daniel Webster (SSBN-626) was converted to the second Moored Training Ship (MTS-2 / MTS-626) in 1993. The Moored Training Ship Site is located at Naval Weapons Station Charleston in Goose Creek, South Carolina. Sam Rayburn'' is scheduled to operate as an MTS until 2014 while undergoing shipyard availabilities at four-year intervals.
