USS Seneca (AT-91) - Decommissioning

Decommissioning

Decommissioned in July 1971, Seneca was transferred to the Maritime Administration on 18 November 1971 for lay up with the James River Group, National Defense Reserve Fleet, Fort Eustis, Virginia. She was struck from the Naval Vessel Register on 30 October 1985. In the late 1980s, the ship was modified at the United States Coast Guard Yard for use as floating laboratory space. The ship was moored at the former Engineering Experiment Station in Annapolis, Maryland, later part of the Carderock Division of the Naval Surface Warfare Center. It continued to serve in this capacity until 18 June 1997, when it was towed to Portsmouth, Virginia. It was finally disposed of as a target on 21 July 2003.
