The Project 1135 Burevestnik (Storm Petrel) class were a series of frigates built for the Soviet Navy. These ships are commonly known by their NATO reporting class name of Krivak and are divided into Krivak I, Krivak II (both navy), and Krivak III (coast guard) classes.

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. Currently 7 of Nerey subclass are in FSB Coast Guard and one is part of Ukrainian Navy.

The ship's unique features—the bow missile box, the stack and the angled mast, earned it a rap-like nickname among U. S. sailors that comes from their foreign ship silhouette identification training — "Hot dog pack, Smokestack, Guns in Back — Krivak."

How many ships remain in active duty is uncertain. According to some sources Russia has four units in service and the Ukrainian Navy, one. Russian press listed three units operational in February 2008, one with the Baltic Fleet and two with the Black Sea Fleet (BSF).

The Indian Navy ordered six frigates of upgraded Krivak III class as the Talwar class. Three ships were delivered in 2003-2004. Three more were delivered in 2011-2012.

On 12 October 2010, it was announced that the Yantar Yard at Kaliningrad on the Baltic Sea had won a contract to construct three new warships for the Russian Navy. The construction of the frigates for the Russian Navy will be carried out in parallel with the construction of the same-type frigates for the Indian Navy.
