The Udaloy class are a series of anti-submarine destroyers built for the Soviet Navy - The Russian designation is Project 1155 Fregat (Frigate bird). The Project 1155 dates to the 1970s when it was concluded that it was too costly to build large-displacement, multi-role combatants. The concept of a specialized surface ship 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 destroyer, there are variations in SAM and air search radar among units of the class. Based on the Krivak class, the emphasis on ASW left these ships with limited anti-surface and anti-air capabilities.
