USS Prowess (AM-280) was an Admirable-class minesweeper built for the United States Navy during World War II. At war's end she was placed in reserve. In the mid-1960s, she was converted into a training ship for U.S. Naval Reserve personnel. She was transferred to South Vietnam in June 1970 as RVNS Ha Hoi (HQ-13) in the Republic of Vietnam Navy. In 1975, Ha Hoi was seized by North Vietnamese forces and incorporated into the Vietnamese People's Navy. She remained in service until 1998, when she was converted into a training ship. She has since been scrapped.
