USS Shelter (AM-301) was an Admirable-class minesweeper built for the United States Navy during World War II. After service in the Pacific during World War II, Shelter was decommissioned in June 1946 and placed in reserve. In January 1964, she was transferred to South Vietnam for service in the Republic of Vietnam Navy as RVNS Chi Linh (HQ-11). She remained in South Vietnamese service until the collapse of that country in 1975. Chi Linh was one of several ships that fled from South Vietnam to the Philippines. She was then commissioned into the Philippine Navy in April 1976 as RPS Datu Tupas (PS-18), named after a chieftain of Cebu. The ship's fate is not reported in secondary sources.
