Project 1155 Fregat I Udaloy-I class
Project 1155.1 Fregat II Udaloy-II class
Guided Missile Destroyer

Designed primarily as an anti-submarine warfare platform, with a long cruising range and underway replenishment capabilities, Udaloy class ships provide support to surface task forces. Udaloy reflects design changes that addressed the shortcomings of the previous Krivak program; namely the lack of helicopter facilities, limited sonar capabilities, and light air-defenses. The Udaloy has two helicopter hangars with doors that serve as a ramp to the flight deck. The ship uses a Polinom active/passive search/attack sonar system. The Udaloy’s air-defense system consists of 8 Klinok launchers, and the AK-630 and AK-100 gun mounts.

The Project 1155 dates to the 1970s when it was concluded that it was too costly to build large-displacement, single-role combatants. The concept of a specialized surface ships was developed by Soviet designers. Two different types of warships were laid down which were designed by the Severnoye Design Bureau: Project 956 destroyer and Project 1155 large antisubmarine ship. Generally the Soviet equivalent of the American Spruance class, there are variations in SAM and air search radar among units of the class. Based on the Krivak class, the empahasis on ASW left these ships with limited anti-surface and anti-air capabilities.

Following Udaloy's commissioning, designers began developing an upgrade package in 1982 to provide more balanced capabilities. The Project 1155.1 Fregat II Class Large ASW Ships [NATO Codename Udaloy II] Russia's only multipurpose warship -- intended to be the Russian counterpart to the American Arleigh Burke-class ships. The Udaloy-II is modified by the replacement of the SS-N-14 by the SS-N-22, reflecting a change in emphasis from ASW to anti-shipping. Other changes include an improved self defense capabilit with the addition of the gun/SAM CIWS systems. Similar to Udaloy externally, it was a new configuration with the Moskit antiship missiles, a twin 130mm gun, the Udav antitorpedo system and several anti-aircraft systems. Powered by a modern gas-turbine engine, it was equipped with more capable sonars, an integrated air defense fire control system, and a number of digital electronic systems based on state-of-the-art circuitry.

The first ship of this new class -- the Admiral Chabanenko -- was laid down at the Yantar Shipyard in Kaliningrad on 28 February 1989, and was launched on 14 December 1992. The ship, 98 percent complete, remained within the shipyard's wall for several years due to financially motivated delays in acceptance tests. The hull of the second Project 1155.1 ship, already assembled by the shipyard, was scrapped.

At the end of 1997 the only large surface combatants active in significant numbers were the newer units of the dozen remaining Sovremennyy-class guided-missile destroyers and a few of the half-dozen remaining operational Udaloy-class destroyers. The Admiral Chabanenko, launched in 1992, was not yet fully operational at the end of 1997. On 28 January 1999 the Admiral Chabanenko BPK large antisubmarine ship was finally commissioned in the Russian Navy.

According to some reports, the eventual goal was to deploy at least fourteen Udaloys in two brigades of seven ships each [roughly 12 Udaloy Is and 2 Udaloy IIs], and possibly three brigades with a total of 21 ships. However, follow-on ships of this class were cancelled in the early 1990s. The nearly complete second unit was scrapped in 1994, and a third planned unit was never laid down.
