Project 1258 alias: Korund ( Russian Корунд , NATO designation: "Yevgenya class") was a class of small mine clearance boats of the Soviet Navy , which was developed to search for sea ​​mines in port entrances, ports and rivers. 92 boats were built by the Soviet Union for its own and friendly naval forces from 1967 onwards.

description

Hull and sonar

Project 1258 was designed as an inexpensive protection system for ports, port approaches and estuaries. Because of the expected short duration of use, the boats could be planned without provisions for accommodating and supplying the seafarers of several guards . With only ten crew members, weak engines and limited armament, the boats only displaced around 90 tons and were small enough to do their job under the spatial restrictions of their areas of operation. The boats of the class were built as double-hulled boats, the hulls were non-magnetic and divided into several watertight compartments.

The hull itself did not have a sonar system to search for underwater contacts, so the crew had to use a crane to deploy appropriate search drones with cameras or a towing sonar, which sent their data via cables to the operations center in the hull.

Armament

The boats were armed with only one twin automatic cannon 25 mm L / 70 2M-3 on the forecastle. Some boats carried a 14.5mm L / 90 2M-7 automatic cannon instead at the beginning of the series .

Four sea ​​mines and twelve depth charges could also be carried. Detected enemy sea mines on the bottom could be marked by buoys that the submersible drones had on board, or an explosive charge with cables could be attached to blow them up. In contrast, anchor towers, the cables of which had been cut, drifted to the surface and were then supposed to be destroyed with the automatic cannons from a safe distance.

export

In addition to project 1258, the variant project 1258E was built for export. The 40 boats did not have the Soviet communication systems and their range increased by 50 nautical miles.

Whereabouts

Of 52 boats built for the Soviet Union, 20 were retired by 2002. The 40 export boats went to Azerbaijan , Angola , Bulgaria , Vietnam , India , Iraq , Kazakhstan , Cuba , Mozambique , Nicaragua , North Yemen , South Yemen , Syria and the Ukraine . A Nicaraguan boat sank in a storm in 1989.
