The USNS Upshur (T-AP-198) was a Barrett-class transport vessel constructed during the late 1940s, originally laid down as the SS President Hayes by the New York Shipbuilding Corporation in Camden, New Jersey. Her hull was laid on September 1, 1949, and she was initially designed in 1947 as a passenger-cargo ship for the American President Lines' post-World War II replacement program. However, before her completion in a civilian configuration, she was requisitioned by the U.S. Navy at the outbreak of the Korean War and converted into a troop and dependent transport. Reassigned to the Military Sea Transportation Service in 1952, the vessel was renamed USNS Upshur in honor of Major General William P. Upshur of the United States Marine Corps. During her service from 1952 to 1973, she performed routine troop transport missions, carrying military personnel and their families across the seas at a time when air travel was less common. Notably, she was involved in the emergency evacuation of military families from Guantanamo Bay Naval Base in 1962, highlighting her role in critical wartime and peacetime operations. In 1973, the USNS Upshur was decommissioned and transferred to the United States Maritime Administration (MARAD). She then served as a merchant marine training ship for the Maine Maritime Academy under the name TV State of Maine until 1995, with occasional assignments to the Massachusetts Maritime Academy. Subsequently, the vessel was transferred to the U.S. Coast Guard and stationed in Mobile, Alabama, serving as a platform for testing maritime firefighting technology. The vessel's later years were marked by damage from hurricanes. In 2005, Hurricane Katrina displaced her from her moorings, settling her across the Mobile River. Further damage occurred from Hurricane Ike in 2008, which caused her to sit at a ten-degree list. By 2011, she was scrapped in Brownsville, Texas. The USNS Upshur’s service history and association with notable naval architect George G. Sharp underscore her significance, although her current condition precludes her listing on the National Register of Historic Places.
