OVERVIEW: The Project 1135 Burevestnik (Storm Petrel) class were a series of frigates built for the Soviet Navy.

DETAILS:These ships were designed as a successor to the Riga class. The design started in the late 1950s and matured as an anti-submarine ship in the 1960s. A total of 40 ships were built, 32 ships for the Soviet Navy (Russian Navy) and 8 modified ships of Nerey (Krivak III) subclass for the KGB Maritime Border Guard. 

Project 1135 M, Burevestnik M (11 ships): This group of ships were fitted with single 100 mm guns instead of the twin 76 mm weapons of the Burevestnik design. They also had a redesigned Variable Depth Sonar (VDS) installation. All of these ships were built in Kaliningrad. NATO referred to these ships as Krivak II class.
