Class Notes:
Hess replaced USNS Michelson T-AGS-23, which was declared unfit for sea by the USCG ca. 1975 while in port in Japan. Much of Michelson's oceanographic research equipment and her embarked Oceanographic Unit Three were transferred to Hess. Alterations resulting from the conversion were largely internal and below the waterline, and outwardly the vessel appeared little changed. The ship’s new role was deep ocean research. She would stay at sea for as long as 34 days, charting the ocean’s topography and other features using multi-beam sonar. Much of this work was done in support of the Trident Fleet Ballistic Missile Submarine Program. She conducted this work for nearly 20 years. She was named for the geologist Harry Hammond Hess.
