Description


Introduction

The Project 1155 Fregat class is an anti-submarine warfare destroyer of Soviet origin, known in the West as the Udaloy class. It was developed in the mid 1970's for the anti-submarine role and was to serve alongside the Project 956 Sarych (NATO: Sovremenny) class that serves in the anti-shipping and air defense role. Udaloy is the widely used NATO reporting name. The official Soviet designation is Project 1155 and its nickname is Fregat, Russian for "frigate bird". The Project 1155 class replaced the older Project 1134A Berkut-A (NATO: Kresta II) class. Twelve of these ships were produced, with the final one commissioned just after the fall of the Soviet Union.

Layout

The hull design is inspired by the Project 1135 Burevestnik (NATO: Krivak) class destroyer and a similar gas turbine propulsion system is used. The layout is conventional for Russian standards with the guns on the forward deck, large missile launchers on either side the bridge, funnels and various sensors on the superstructure and the hanger and helicopter deck at the rear. Two Ka-27PL anti-submarine warfare helicopters are carried.

Firepower

The main weapon system of the Udaloy class are the SS-N-14 Silex anti-submarine missiles that are launched from the large quad launchers under the bridge. At the rear two quadruple 533mm torpedo launchers are fitted. Surface targets can be engaged using the two single 100mm guns. Short range air defense consists of 8 octuple vertical launchers for the SA-N-9 surface to air missile. Self defense consists of four 30mm AK-630 CIWS systems. The two Ka-27 helicoptes can also be used in the anti-submarine role. Sea mines can also be carried.

Sensors

The sensons consist of a hull mounted active sonar, air and surface search radars and various fire control and IFF systems. Datalinks allow the Project 1155 to exchange data with other vessels. Countermeasures consist of various chaff launchers and ESM and ECM systems.

Mobility

The Project 1155 Fregat class features a combined gas and gas propulsion system. The system consists of two large gas turbines and two minor gas turbines that power two shafts. A maximum speed of 28 to 30 knots can be achieved. The maximum range is 7.700 nm at 18 knots.

Users

A total of 12 ships were built by the Soviet navy, with the final one commissioned after the break up of the Soviet Union. In addition, only one of the improved Project 1155.1 Fregat II, described separately, was completed with the two other hulls scrapped. All Project 1155 Fregat were transferred to the Russian navy. By 2020 four have been retired, one is held in reserve and 7 are in service. One ships is receiving a service life extension and is modernized with a new set of armament. If this proves successful more may be modernized in the future.
