Project 1252 'Izumrud' (Изумруд - 'Emerald') (NATO reporting name: Zhenya class) were a group of three minesweepers built for the Soviet Navy in the late 1960s. The ships were a glass-reinforced plastic (GRP)-hulled version of the preceding wooden-hulled Vanya class. They were intended to be a prototype of an advanced design, instead the Soviet Navy returned to wooden-hulled minesweeper construction with the following Sonya class. Of the three minesweepers, one was lost in an explosion in 1989 and the fate of the other two is unknown.
