Project 21956 Multi-purpose Ship

Project 21956 New Destroyer Numerous naval forces worldwide face a complex array of military and civilian challenges. Possessing a national navy is not only a matter of prestige, but absolutely critical to a countrys self-defence. Few countries in the world have the research, engineering and manufacturing capabilities to independently design and build warships. The Severnoye Design Bureau has been successfully working in this area for over 60 years. While constantly analysing new developments, naval products and market demands, the Severnoye Design Bureau uses new design solutions, applying state-of-the-art technologies to offer for export the most sought after designs for surface combatants, destroyers, frigates, corvettes, medium landing ships and boats.

The Severnoye Design Bureau offered the Project 21956 class destroyer in 2007 [no takers by 2014] with an approximate displacement of 9,000 tons. The ship is designed to counteract surface combatants and submarines, support anti-submarine and air defence operations of ships and vessels in ocean and sea areas in surface groups and task forces.

The ship solves the following combat tasks:

  • combat operations in ocean and sea areas against the main hostile naval forces
  • observation of tactical surface and underwater situation and collection of data for employment of strike missile and anti-submarine weapons
  • automated support to helicopters of naval aviation, included in the forces, to detect hostile surface and underwater forces and employment of strike missile and anti-submarine weapons
  • destruction of hostile surface combatants, vessels and landing means
  • air and anti-boat defence of ships and transports
  • preparation and analysis of tactical situation in real time
  • fire support to landing forces
  • patrolling and combat service jointly with other ships.

The ships hull is designed with a short forecastle and round bilge hull shape. There are two knuckles on the surface part of the hull: the first starts from the transom and is hidden one-quarter of ships length from the fore; the second passes under the forecastle at the upper deck level. The aft part of the transom is substantially forward-inclined making the ships silhouette streamlined. Hull lines and a sharp stem provide the best sea keeping abilities. The structure and strength of the hull, armament, machinery, gears, systems and hull fittings do not restrict safe navigation of the ship during storms with running and heading allowed as per navigability conditions.

To improve navigability, conditions of armament use, and crew comfort, a stabiliser with fixed rudders is used on the Project 21956 ship. When compared to the earlier applied stabilisers, with retractable rudders, the new stabiliser is in the form of a single unit taking up much less space in the ships compartments. Navigability of the ship with the operating stabiliser allows use of armament and machinery without limitations at up to Sea State 5 levels.

Magazines for storage of strike and anti-aircraft guided missiles are located in the aft and fore parts of the ship, under the deck with added structural protection for the magazines. Optimal arrangement of radars on the foremast and mainmast enables the ships radars to be used to their maximum tactical and technical capacities.A hangar and helo deck for landing and storing a helicopter weighing up to 12.5 tons are provided in the aft part of the ship. There is a bulb dome in the fore part of the ship, where the sonar system is located, for the detection of submarines and torpedoes.

The ships futuristic design is defined by new developments with the armament systems, aimed at further increasing their efficiency by limiting their mass and size. This is crucial as it enables a ship of this class to be kept in a set displacement range. Other design achievements have been made in the ships power engineering, stealth characteristics.

Physical fields of the ship have been minimised to increase its stealth characteristics. Concerning its surface parts, a decrease in the radar cross section (RCS) has been provided through a new special hull and superstructure architecture design. Because of this, the RCS has decreased several times in comparison with ships of similar class with traditional architectures. This has decreased the ships detection range by hostile radars while increasing the operational efficiency of its active and passive electronic warfare systems. Structural stealth measures, together with the use of electronic armament and antiaircraft -guided facilities, have substantially increased the ships protection against anti-ship missiles.

Arrangement of antennas of radio-technical facilities and firing systems has been implemented taking into account the necessity of provision of scanning patterns. To provide electromagnetic compatibility of radars and control systems for anti-aircraft guided and artillery systems, an electronic suppression system that protects all the ships radio-technical facilities has been installed.

Planning automation and centralisation of a joint safe weapon deployment system are one of the most important factors in the improvement of combat control. This allows to maximally use its combat capabilities and to improve efficiency of weapon joint deployment. To solve these tasks a Combat Management System (CMS) has been installed onboard the ship. This system enables information exchange with surface and airborne weapon carriers. Collection and distribution of operational information between specific addressees is also carried out by the CMS. The main feature of the new CMS is its use of a wide computer network with reserve information buses that provide a higher degree of survivability when compared to ordinary centralised computer systems.

Apart from provision of combat task solutions, the system is easy to maintain and easy to operate for crew. This requirement is met by means of simulators designed for crew training, general system monitoring, automation of weapon control systems and effective communications.

Airborne and surface targets can be detected by multi-purpose Fregat and Rif-M type radars fitted with phased-array antennas. The Poima-E integrated system for processing radar information was acquired for outputting target distribution and target designation data to the ships weapons. Surface targets can be detected by the Mineral-ME radar system, Ka-31 helicopter, navigation radar and two electro-optical sights. Underwater targets can be detected by the Zarya-ME-03 sonar system, Vinyetka-ME system and Ka-28 antisubmarine helicopter.

The principal strike missile weapon of the Project 21956 ship is the integrated Club-N missile system designed for defeating large surface targets at large ranges. The Club-N comprises the under-deck, 3S-14E vertical launch systems for 16 -54E type missiles and the 3R-14N fire control system. The systems capabilities are as follows:

  • Large range (up to 220 km) enabling it to combine tactical and operational capabilities as well as performing a containment function
  • The combat stage is separated at the flight speed of no less than 700 m/sec and flight elevation at approach to target within 5-10 meters
  • High probability of cruise missile (CM) 3-54E self-vectoring at the final section of the flight, homing head high interference protection and its selectivity
  • Ability to select CM flight route including direction of CM approach to target
  • Automatically plan CM combat employment and calculate firing efficiency key figures (access probability and detection probability of marine target by homing head, calculation of number of CM required to achieve the assigned level of destruction etc).

For firing against all types of submarines, the ship is provided with two missile-torpedo launchers that accommodate 91RE1 anti-submarine missiles or UGST or UETT universal torpedoes. Employment of 91RE1 (91RE2) anti-submarine missiles as part of the Club-N integrated missile system broadens submarines access zone while maintaining quite high destruction probability which increases combat facilities when solving anti-submarine defence tasks of for protected ships. 91RTE2 anti-submarine vertical missiles can be arranged in the unified 3S-14E launcher. Whether 3-54TE or 91RTE2 missiles are loaded into launcher is defined by the ships combat employment tasks. The integrated Club-N missile systems incorporation of the ships 3R-14N firing control system enables it to control both strike and anti-submarine weapons as well as anti-torpedo weapons.

To repulse attacks from aircraft carriers at large ranges with the purpose of moving off employment line for air weapons, anti-aircraft and anti-ship cruise missiles, anti-radar missiles, Rif-M anti-aircraft guided missile system is fitted on the ship. Missiles are launched from vertical launchers comprising six turrets, each designed for eight 48N6-2 type missiles with a strike range of up to 150 km, or for 32 9-96 type missiles with a strike range of 40 km (a packet of four 9-96 missiles is loaded instead of one 48N6-2 missile).

To repulse anti-ship missile attacks, the ship is fitted with the Kashtan- system that can hit targets 10km away. To fire against sea and shore targets as well as to provide fire support for landing assault troops, the ship is equipped with 130mm-130 artillery system with a firing range of up to 23km. To perform electronic warfare, the ships weaponry comprises the K-25E electronic warfare system and K-308-5 chaff launching system.

The integrated gas turbine unit comprises two cruise and two boost turbines, cruise reduction gears and cruise reduction gear adapter. The total power of gas-turbine unit makes 74,000 hp (54,420 kW) that enables increase of the ship speed up to 30 knots. Cruise range is about 5,800 miles. The ships power plant comprises four diesel generators with a total capacity of 5,000 kW and one autonomous diesel generator with 600Kw capacity for power supply to the ships gears, for controlling the vessels motion and control, for its weapon systems, damage control means and for the domestic needs of the crew.

Onboard accommodation (including for flight crews) provides resting space for approximately 300 crewmembers for 30 days at sea.
