USNS Shearwater (T-AG-177) was a Shearwater-class miscellaneous auxiliary built during the final months of World War II for the US Army as FS-411 (Design 381 coastal freighter) by Hickinbotham Brothers Shipbuilders. FS-411 was Coast Guard manned operating in the Central and Western Pacific, including Hawaii, Saipan, Tinian, Guam, during the closing days of the war.[1]
She was placed into service by the U.S. Navy from 1964 to 1969 as USNS Shearwater (T-AG-177). After this service, she was transferred back to the U.S. Army.
Shearwater began her naval service as a survey support ship with the Military Sea Transportation Service in May 1964. Operated by a Civil Service crew, she operated in the Atlantic Ocean until mid-February 1969, when she was transferred back to the U.S. Army.
As of 2007, Shearwater was active as a fishing vessel based at Reedville, Virginia.[2] She was retired in 2013 and reefed off the coast of Delaware onto the Del-Jersey-Land Inshore Reef site in 2015.[3]
