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]

Design

The hull is made of steel. ^[1]

Early ships were 58 metres (190 ft) long with a straight-up bridge structure. ^[1]

Later ships were 60 metres (200 ft) long with a double-level bridge structure and added 25 mm guns. ^[1]

  Bangladesh

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]
