Burevestnik M (Project 1135M (Krivak II))

The Project 1135M (NATO reporting name Krivak II) was a class of frigates built for the Soviet Navy, an improved variant of the Project 1135 Burevestnik (Krivak I) class. These ships were primarily designed for anti-submarine warfare and surface combat, featuring a powerful armament suite including SS-N-14 Silex anti-submarine missiles.

Developed in the mid-1970s, the Project 1135M class was designed to rectify the firepower limitations of its predecessor by replacing the twin 76mm guns with more powerful single 100mm AK-100 main guns and integrating an upgraded sonar suite. The lead ship, Rezvy, entered service with the Soviet Navy in 1975, followed by ten additional vessels commissioned through 1981. Throughout the Cold War, these frigates were heavily deployed across the Soviet Northern, Baltic, Pacific, and Black Sea Fleets to track Western submarines and project naval power. While most units were decommissioned and scrapped in the post-Soviet era, the Pytlivyy remains active with the Russian Black Sea Fleet today, showcasing the enduring design of the class.
