Natya-class were a group of minesweepers built for the Soviet Navy and export
customers during the 1970s and 1980s (58 ships were built). The Soviet designation
was Project 266M Akvamarin. The ships were used for ocean minesweeping.
design evolved from the Yurka class minesweeper with new demining equipment including
more advanced sonar and closed circuit TV. A stern ramp made recovering sweeps
easier. The hull was built of low magnetic steel. To protect against acoustic
mines the foundations main engines and diesel generators were padded with rubber,
installation of mechanisms for isolating dampers; installation of flexible inserts
in pipes; application of low-noise propellers controlled step large-diameter,
as well as the installation of low-noise machinery and equipment. An electrical
field compensator was also installed.
