The -class minesweeper was a class of ships built for the Soviet Navy. They existed in two versions: Project 59 and Project 73K.

History Work on the -class began in 1938 and 1939 when numbers 370 and 363 were laid down in Leningrad.The first two ships were Vladimir Polukhin (T-250), for whom the class was named, and Vasiliy Gromov (T-254); they were completed in 1942 and 1943. They were supposed to be finished before World War II but there were delays in delivering turbines and boilers. The modified version, Project 73k, consisted of 20 ships laid down in 1941 at the number 201 yard at the Sevastopol Yard. None were finished during World War II, and only 15 ended up being completed afterwards. They were initially laid down with turbines but completed with diesels.

The class was designed to assume reconnaissance mine-sweeping in long range and far away areas. They also were supposed to assume mine warfare support for large squadrons. Some were active in the Baltic and Black Seas. Some were operated by the US Navy in lend-lease. All the ships were reclassified in 1956 as miscellaneous auxiliary vessels.
