Description: The Soviet Union developed the Project 1155, also referred to as Fregat and Udaloy, class destroyers in the 1970s on the basis of the Krivak class anti-submarine frigate. These ships were designed to engage submarines as their primary target with surface ships being their secondary target. The Udaloy class destroyers sensor suite includes Fregat MA air surveillance radar, hull mounted sonar and variable depth sonar. The propulsion system is based in four gas turbines in a COmbined Gas And Gas (COGAG) arrangement allowing a top speed of 35 knots. These destroyers are equipped with hangar and flight deck for two Ka-25 and/or Ka-27 anti-submarine warfare (ASW) helicopters. The Soviet Navy and Russian Navy commissioned 13 Udaloy class destroyers between 1980 and 1999.

The project 1155.1, also referred to as Udaloy II, is an improved variant of the Project 1155 class destroyer featuring eight Moskit supersonic anti-ship missiles instead of the eight SS-N-14 anti-submarine/anti-ship missiles, one 130mm two-barrel AK-130 gun replacing the AK-100 gun, and two Kasthan/Kortik close-in weapon systems with 64 missiles replacing four AK-630 gun systems. The Udaloy II incorporates the Udav-1 anti-submarine rocket system instead of RBU-6000. The torpedo tubes (2x4) were replaced by the RPK-2 anti-submarines missile system. Besides, the sensor system was improved as well with the sonar systems performance exceeding Udaloy I as well as the air defense system effectiveness against airborne threats. The Russian Navy commissioned a single Udaloy II destroyer in 1999 with two additional ships under construction at the time of the Soviet Union collapse being scrapped. An Udaloy I class destroyer was upgraded to the Udaloy II standard in 2013 also being deployed with the Russian Northern fleety. Udaloy II class destroyers will remain in the active duty well into the 2020s.
