HMSAS Protea was a survey ship of the South African Navy. The ship was originally built as a Flower-class corvette for the Royal Navy during World War II and served as HMS Rockrose (pennant number: K51). Rockrose was initially assigned to convoy escort duties in the North Atlantic after her completion in 1941 but was later transferred to South African waters and then to the Far East with the same mission. She returned home in 1945 and was paid off.
Two years later the ship was purchased by South Africa and was converted into a survey ship in 1949. Protea was obsolete by the late 1950s and was placed in reserve in 1957. The ship was sold in 1962 and was converted into a fishing trawler with the name of Justin. The company subsequently failed and she was scrapped in 1967.
