Project 10750 Sapfir (Lida class by the NATO classification) is a class of small
minesweeper of the Soviet and Russian navies, which was developed to search for
sea mines in port entrances, ports and rivers. Ten vessels were built by the Soviet
Union and later by Russia from 1986 for the Russian Navy.
The hulls of minesweeper
are made of fiberglass, have a double bottom and are divided into nine watertight
compartments. To search for underwater contacts, a dome with a Kabarga-A1 sonar
is built into the hull. On the aft of the ship there is a working platform on
which a 5.3-tonne crane is mounted, with which the search robot and minesweeping
gear can be brought in and out.
The boats are armed with a 30 mm turret
AK-306 on the forecastle. In addition, eight Igla-1 anti-aircraft missiles can
be used against flying targets. Four sea mines along with KIU-1 Luch or KIU-2M
Anakonda mine searcher-and-destroyer or GKT-3-MO contact sweep, AT-6 acoustic
sweep or SEMT-1 electromagnetic sweep, AT-6 acoustic sweep or 2x200 meters of
the detonation cord can be carried.
