Yakhont (Project 1265 (Sonya))

The Project 1265 Sonya-class is a series of coastal minesweepers developed by the Soviet Union for mine countermeasures operations. These vessels are designed to detect and neutralize various types of mines, including contact, acoustic, and magnetic mines, in coastal waters and harbors.

Designed by the Western Design Bureau in the late 1960s, the Project 1265 Yakhont was developed to replace the aging Project 257 class, featuring a low-magnetic fiberglass-coated wooden hull to survive modern mine threats. The lead vessel of the class entered service with the Soviet Navy in 1971, initiating a prolific production run of over 70 hulls built at the Kolpino and Vladivostok shipyards. Throughout the Cold War, these vessels patrolled critical Soviet coastal waters and choke points, and several units were exported to allied nations including Cuba, Vietnam, Syria, and Bulgaria. Today, while many units have been retired, a modernized contingent of Sonya-class minesweepers remains active in the Russian Navy's Baltic, Northern, and Pacific Fleets, demonstrating the enduring utility of the design.
