The USS Stalwart (MSO-493) was an Agile-class minesweeper built for the U.S. Navy, primarily tasked with detecting and removing naval mines to ensure safe passage for maritime vessels. Laid down on June 22, 1954, by Broward Marine Shipbuilding Co. in Fort Lauderdale, Florida, she was launched on December 3, 1955, and commissioned on April 23, 1957. The vessel’s hull designation was initially AM-493 before being reclassified as MSO-493, indicating her role as a minesweeper, ocean (MSO). Stalwart's dimensions and technical specifications are not detailed in the provided content, but as an Agile-class minesweeper, she would have been designed for mine countermeasure operations, featuring specialized equipment for mine detection and clearance. Upon commissioning, she was assigned to the Mine Force of the Atlantic Fleet, with Charleston, South Carolina, designated as her home port. Throughout her service, USS Stalwart participated in various operational activities, including training, fleet exercises, and special mine hunting projects. Notably, she supported U.S. 6th Fleet operations during the Lebanon crisis in 1957 and was involved in joint exercises with Canada off South Carolina in 1961. Her service record also includes multiple overhauls to update her systems, and she was recognized for excellence with awards such as the Battle Efficiency "E" in August 1958 and the minesweeping "M" in August 1960. A significant event occurred in June 1966, when a fire in her machinery space at San Juan, Puerto Rico, caused her to capsize and sink after a nine-hour firefight involving her crew and personnel from the USS Beverly W. Reid. She was later refloated in July 1966 by rescue ships and towed back to Charleston. USS Stalwart was decommissioned on August 24, 1966, and her name was struck from the Navy list on March 1, 1967. She was subsequently scrapped, marking the end of her service as a key element of American mine countermeasure operations during the Cold War era.
