USNS Michelson T-AGS-23
Michelson was operated by the U.S. Naval Oceanographic Office for the U.S. Navy Office of Special Projects in support of the U.S. Navy Fleet Ballistic Missile Program. Three ships were converted for this purpose: Michelson, and identical sister ships USNS Bowditch (T-AGS-21) and USNS Dutton (T-AGS-22).

Varying numbers of civilian scientists and engineers managed survey operations, and maintained certain navigation and sonar equipment, usually about 12 oceanographers from the Naval Oceanographic Office, some personnel from the Naval Applied Sciences Laboratory (NASL, later NSSNF), and about 7 technical representatives from private corporations.

Michelson was taken out of service and disposed of by MARAD sale on September 22, 1977.
