266* Akvamarine/Natya I/II class
Standard general-purpose oceangoing minesweeper; also intended as a coastal ASW escort in wartime. Production resumed in the 1990's, apparently mainly for export, but several of the new units were acquired by the Russian navy. Later units vary in weapons and electronics.
Natya II: Variant of the standard 'Natya-I' class outfitted as a trials ship for a new minehunting sonar. Probably capable of serving as an operational minehunter. Most armament and sweep gear omitted from this unit.
Two units have been tranfered to Ukraine.
