USNS Wyman (T-AGS-34) was an oceanographic survey vessel constructed by the Defoe Shipbuilding Company in Bay City, Michigan. Laid down on July 18, 1968, and launched on October 30, 1969, she was sponsored by Mrs. Francis J. Blouin, wife of a high-ranking naval officer. The vessel was officially accepted into service by the Military Sealift Command (MSC) on November 19, 1971, at the Boston Naval Shipyard. Designed for hydrographic and oceanographic research, Wyman operated with a civilian crew under the technical guidance of the Oceanographer of the Navy. Her crew comprised MSC personnel along with civilian technicians and scientists from the Naval Oceanographic Office (NAVOCEANO). During her early service, Wyman was assigned to MSC Atlantic, conducting numerous cruises in the North Atlantic region, visiting ports such as Reykjavik, Tromsø, Bergen, Rota, Lisbon, and Glasgow in the early 1970s. Notably, in 1974, she became one of the first MSC ships to have a woman serve aboard as the Medical Officer. In November 1974, Wyman was transferred to MSC Pacific for a brief deployment into the summer of 1975, after which she returned to MSC Atlantic at Port Canaveral, Florida, remaining active into 1979. The vessel's scientific equipment included early echo sounding systems and the Hydrographic Data Acquisition System (HDAS), featuring two PDP-9 computers with shared disk drives and Calcomp plotters for real-time navigation. In the mid-1970s, her original single-beam echo sounder was replaced with a more advanced bottom topography survey system, BOTOSS, mounted on a keel fairing to mitigate air bubble interference. Wyman was struck from the Naval Vessel Register on May 3, 1999, and transferred to the Maritime Administration. She was laid up in the National Defense Reserve Fleet at Suisun Bay, California, from March 21, 2001. The vessel was eventually scrapped by ESCO Marine, Inc., completing her dismantling on October 1, 2014. Her service contributed significantly to U.S. oceanographic and hydrographic capabilities during her operational years.
