The T43 (Projet 254) were a class of open-ocean minesweepers built for the Soviet Navy from 1948 to 1957. It was exported to client states; the People's Republic of China and Poland produced additional ships. Some hulls were converted to other uses by various users.[1] Examples remained in service in 2015.[5]
Bangladesh ordered a new ship from China in 1993, based on the Chinese T43 variant, which entered service in 1996. The Tamir-II sonar was replaced by a C-Tech sonar in 1998. It was used mainly as a patrol ship.[4] An order for three more ships was not fulfilled.[11]
Bulgaria received three short-hulled ships from the Soviet Union in 1953. By 1989, one was cannibalized for parts and another was used as a spy ship.[12] All were retired by 2009.[13]
The People's Republic of China received about four short-hulled ships from the Soviet Union in the 1950s.[3] China constructed over 60[3] of a variant called Type 6610[5] or Type 010,[3] most of which were of the long-hull type.[3] Production began in 1956 and continued to at least the early 1990s.[5] Some were converted for other roles, including patrol, surveying, submarine rescue, and civilian research.[3]
Poland built 12 ships from 1957 to 1962, including four short hulls.[19] Of the short hulls, one was converted into a spy ship,[2] one was retired in 1987, and another was retired in 1988.[20] None were in service by 2009.[21]
The Soviet Union built over 200 hulls, including those converted to other uses included diving ships, tenders, and KGB patrol ships. They were being phased out in 1989 when only 35 remained in service.[1]
