Krivak Class Frigate - Versions

Versions

• Project 1135, Burevestnik: Design process started in 1956 as an anti-surface frigate successor to the Riga-class frigate. The role changed to an anti-submarine ship powered by gas turbines and armed with the SS-N-14 missile. The main building yards were Zhdanov Yard, Leningrad, Yantar Yard, Kaliningrad and Kamysh Burun yard, Kerch. NATO referred to these ships as Krivak I class.

• Project 1135 M, Burevestnik M: This group of ships were fitted with single 100mm guns instead of the twin 76mm weapons of the Burevestnik. 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.

• Project 1135.1 Nerei (Nereus): These ships lacked the SS-N-14 missile system, which was replaced by a helicopter and hangar, and only one 100 mm gun at the bow of the ship. These ships were built for and operated by the KGB Maritime Border Guard. NATO referred to these ships as Krivak III class.

• Project 1135.2: This was a modernisation of the Burevestnik ships Zharkiy and Leningradski Komsomolets (renamed Legkiy). The refit involved replacing the RBU-6000 anti submarine mortars with SS-N-25 anti-ship missiles, new radar, sonar and ECM equipment. The two ships completed their refits in 1991 and others were to have been modernised but the programme was cancelled with the collapse of the Soviet Union. NATO referred to these ships as Krivak IV class.

• Talwar class: this is an advanced derivative built for the Indian Navy from 1999 to 2003. It could have been called Krivak-IV.

• Admiral Grigorovich class (also known as project 11356 (or 1135.6)): This is expected to be completed in similar configuration as the Talwar class. Three ships are ordered for the Black Sea Fleet, with the first one laid down on December 18, 2010; two or more ships planned. These ships could have been called the Krivak-V class.
