   The Udaloy I class (Project 1155 Fregat) were considered large ASW ships (bolshoy protivolodochny korabl) by Soviets. The programme was initiated in 1972, and two ships, Udaloy and Vitse-Admiral Kulakov were operational by early 1982. Based upon the Krivak class, the Udaloy I ships were intended as long-range ASW platforms, with an underway replenishment capability, to provide support for surface task forces. The series eventually yielded 12 vessels. Seven ships remain in service, these being maintained partly at the expense of the Sovremenny class destroyers.

   The Udaloy I class is armed with two quadruple launchers for the Rastrub (SS-N-14 Silex) missiles. A unique twin hangar system with associated helicopter flight deck is located aft for two Ka-27 Helix-A ASW helicopter. Additional ASW equipment comprises a Polinom (Horse Jaw) active/passive search/attack sonar system. For air defence, the Udaloy I ships are fitted with eight six-round vertical launchers for the Klinok (SA-N-9 Gauntlet) missiles, of which 64 are carried. These can engage aerial targets at a range of up to 12 km and at altitudes as low as three meters and up to 12 192 m.

   A single follow-on vessel of the Udaloy II (Project 1155.1 Fregat) class was commissioned in 1995. This design was intended to provide more balanced capabilities, and as such introduced two quadruple P-270 Moskit (SS-N-22 Sunburn) anti-ship missile launchers in place of the Rastrub. For self-defence, two Kortik (CADS-N-1) combined gun/missile CIWS were added, each incorporating two six-barrel 30-mm guns and eight 9M87/9M88 (SA-N-11 Grison) surface-to-air missiles. A new twin 130-mm dual purpose gun is also fitted, whilst ASW capability is maintained by Viyoga (SS-N-15 Starfish) missiles. Although two more vessels were planned, only Admiral Chabanenko has entered Northern Fleet service.
