LKL Sūduvis (M52) is a minehunter of the Lithuanian Naval Force. Built in West Germany in 1957 as Koblenz (M1071), a Lindau-class (or Type 320) minesweeper for the German Navy, she was upgraded to a Type 331 minehunter in the early 1960s. Germany donated Koblenz to the Lithuanian Naval Force in 1999. The ship, renamed Sūduvis, formed the nucleus of the Lithuanian Naval Force's Squadron of Mine-hunters, which was established on 22 June 1999. The squadron was augmented in 2001 with the similar donation of sister shipMarburg, which became Kursis (M51).
