The USS Sentinel (AMCU-39) was originally constructed as a large landing craft of the LCI(L)-351 class, built by Defoe Shipbuilding Company in Bay City, Michigan. Laid down on 8 February 1944 and launched on 9 March 1944, she was commissioned shortly thereafter as USS LCI(L)-1052 on 21 March 1944. Designed for amphibious operations, this vessel measured approximately 158 feet in length, with a beam of around 23 feet, and was equipped to carry troops, vehicles, and supplies during World War II. Following her shakedown off the East Coast, LCI(L)-1052 was assigned to the Atlantic Fleet but was quickly transferred to the Pacific Theater, joining the 19th Fleet Amphibious Force in July 1944. Her initial duties involved ferrying passengers, mail, and supplies among key locations such as Kwajalein Atoll, Eniwetok, and Ulithi. She operated in the Caroline Islands, notably ferrying recreation parties and supporting logistical operations for the U.S. Navy. During her service, she was engaged in routine transport duties around the Pacific, including at Leyte Gulf, until the end of hostilities in August 1945. After the war, she remained stationed in the Pacific, performing similar support tasks in Leyte Gulf until September 1945, when she sailed via the Marshalls to Hawaii. She returned to the U.S. West Coast, arriving in San Francisco in February 1946, and was decommissioned in September 1946. In 1952, she was renamed USS Sentinel and reclassified as AMCU-39, marking her transition from a landing craft to a coastal minesweeper. A conversion to her new role was undertaken at Puget Sound Naval Shipyard, completed in May 1954. Despite her conversion, the USS Sentinel saw no further active service and was ultimately struck from the Navy list on 1 January 1960. Her service highlights her role in World War II logistics and her later attempted conversion into a minesweeper, reflecting her versatility and the shifting needs of the Navy during the post-war period.
