The USS Gallant (MSO-489) was an Aggressive-class minesweeper constructed for the United States Navy, serving from 1955 to 1994. Laid down on 21 May 1953 by J. M. Martinac Shipbuilding Corp. in Tacoma, Washington, she was launched on 4 June 1954 and commissioned at Tacoma on 14 September 1955. Originally classified as AM-489, she was reclassified as MSO-489 on 7 February 1955, indicating her role as a minesweeper (Ocean) vessel. Designed for mine countermeasure operations, Gallant had a versatile service life, primarily based out of Long Beach, California, where she was assigned to Mine Division 96. Her early service included readiness exercises extending as far south as Acapulco, Mexico, and notable rescue operations such as saving two crew members of a Navy plane off Santa Catalina Island. Gallant participated in multiple deployments with the U.S. 7th Fleet, involving joint training with allied navies including South Korea, Taiwan, Japan, and Canada. Her operations took her to Korean waters, Formosa (Taiwan), and Southeast Asia, where she conducted peacekeeping, patrol, and mine-sweeping duties. Throughout her career, Gallant was actively involved in fleet readiness exercises, mine countermeasure training, and operations supporting U.S. and allied naval objectives. During the Vietnam War, she notably contributed to "Operation Market Time," patrolling South Vietnamese waters to interdict enemy infiltration and boarding suspicious vessels. Her service included patrols in the East and South China Seas, as well as blockade and coastal operations off Vietnam. Gallant earned recognition for her operational excellence, winning the Battle Efficiency Competition Award "E" and the Minesweeping "M" in 1959. She also appeared in popular culture, notably being used in the filming of Elvis Presley's movie "Easy Come, Easy Go" in 1966. Decommissioned on 29 April 1994, USS Gallant was subsequently sold to Taiwan under the Security Assistance Program and renamed Yung Ku (M 1308), marking the end of her distinguished 39-year career in naval service.
