The USS Advent (AM-83) was an Adroit-class minesweeper constructed for the United States Navy during World War II. Laid down on August 18, 1941, by the Commercial Iron Works in Portland, Oregon, she was launched on March 12, 1942, and officially commissioned on August 19, 1942. Designed primarily for minesweeping operations, the vessel also served in escort and patrol roles across the South and West Pacific theaters. Throughout her wartime service, USS Advent operated predominantly out of Noumea, New Caledonia, from May to October 1943. During this period, she undertook convoy screening duties, making port calls at strategic locations such as Espiritu Santo, Sydney, Tongatapu, Efate, and Guadalcanal. In mid-October 1943, she shifted her base to Guadalcanal, continuing her patrol and escort missions to ports including the Treasury Islands, Efate, Bougainville, and Ulithi. On June 1, 1944, her designation changed from USS Advent to USS PC-1587, reflecting her reassignment as a submarine chaser. During her service as PC-1587, she was based at Espiritu Santo between August and October 1944, notable for rescuing the crew of a downed PBY aircraft on October 11. She also operated out of Guadalcanal and shifted her base to Ulithi in December of that year. By April 1945, she had completed multiple convoy runs to locations such as Kossol Roads, Palau, and Guam, and took on patrol duties at Saipan. Her escort missions extended to Iwo Jima, the Bonin Islands, Guam, and Tinian. Following the end of hostilities, PC-1587 prepared for decommissioning. She sailed back to California arriving in San Francisco Bay on November 13, 1945. Deactivation preparations commenced soon after, leading to her decommissioning on January 22, 1946. Her name was struck from the Navy list on February 25, 1946, and she was transferred to the Maritime Commission for disposal in March 1948. The USS Advent/PC-1587 served as a versatile vessel contributing significantly to convoy protection and patrol operations in the Pacific during World War II.
