Project 1253 alias: Almas ( Russian Алмаз for diamond ) was a class of small mine clearance boats of the Soviet Navy that had been developed to search for sea ​​mines in the coastal apron. Eleven ships were built by the Soviet Union from 1962.

description

Project 1253 was a specialty among the minesweepers of the Soviet Union. The small boats with only seven crew members were supposed to blow up breaches in minefields that had previously been tracked down by other ships and aircraft. Similar to the German seal class , the boats could also be remotely controlled from a lead ship in groups of several boats via an automated system. For this purpose, two command boats of the project 1253W were built based on the project 257D .

The vehicles of project 1253 had a hull made of several layers of wood on which an aluminum alloy structure was placed. In the middle of the ship was a large cable drum on which the detonating cord, which was up to 2,000 meters long, was wound. The boats were driven by a diesel engine that was used to operate a water jet drive .

The boats from Project 1253 were not armed.

Units and whereabouts

Two boats from Project 1253 were built as test vehicles, followed by Project 1253A with six boats and finally three reworked boats from Project 12531. By 1998, all boats were decommissioned.
