USNS Tanner (T-AGS-40), was built for the United States Navy as a fast oceanographic research vessel by Bethlehem Steel Corporation at its Sparrows Point Yard in Maryland in 1990.
 The vessel was the second oceanographic research ship to bear the name of Zera Luther Tanner, a noted oceanographer and inventor of a patented sounding machine.
 The vessel experienced catastrophic engine failure in 1993 and was laid up by the Navy and eventually transferred ownership to the Maritime Administration (MARAD).

The ship lay idle in the James River Reserve Fleet until 1996 when she began a conversion process, which removed her underwater sonar domes and equipment.
 The two original engines were removed and a new power plant was installed.
 The newer engine is significantly less powerful than the old engines.
 The sister ship, Maury (T-AGS-39), now the third vessel of the name TS Golden Bear, retained the original and more powerful enterprise engines.

The vessel was modified to increase the accommodations from 108 to 302 persons.
 New lifesaving equipment and upgrades to existing equipment were accomplished as well as enhancements to the habitability requirements of the vessel.
 She was delivered to Maine Maritime Academy on 6 June 1997 and sailed her maiden training cruise the following week.

State of Maine was called into active duty by the Maritime Administration (MARAD) following Hurricane Katrina and provided living quarters for oil rig workers, who were working to repair damaged rigs, and for Federal Law Enforcement Officers assisting in New Orleans.
