Moored training ship

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.

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.
