rary propulsion system with two controllable pitch propellers. They provide high efficiency at the pa- trol/economic speed and gaining high full speed due to pitch opti- misation. The controllable pitch propellers allow using more reli- able and robust irreversible reduc- tion gears which provide mini- mum time to gain full speed astern after full speed ahead (about 90 sec) with maximum head reach of up to 4 ship lengths. Project 22160 patrol ship has a
“deep-V” hull shape optimised for sustaining high speed navigation in arisen seas, a single-island su- perstructure incorporating stealth technologies, and a closed moor- ing arrangement. The ship’s hull and superstructure are fully made of steel, and are reinforced for navigation in a stormy sea. The enclosed bridge and some ship sta- tions are protected against bullets

and splinters. The ship’s lines have no double camber that simplifies construction and repair works and reduces their cost. The crew are accommodated
(in compliance with modern in- ternational standards) in single, double and quadruple-berth cab- ins equipped with washrooms and lavatories. The complement is op- timised and counts at least 50 per- sons, thanks to the introduction of modern automatic equipment, including flight personnel (16 offi- cers and 34 men), and can also pro- vide additional space for accom- modation of another 30 persons making allowance for operational requirements of navies in poten- tial customer countries. Special ac- commodation can be provided for officers and personnel of boarding teams or inspectors (up to 30 per- sons in total). A specialised medi- cal station is available for render- ing emergency aid. To extend the range of mis-

It has high upgrading potential achiev- able thanks to the realisation of a new principle of ship’s weapon systems arrangement: the ship is considered a baseline “platform” in which the composition of weap- ons and equipment - both combat and non-combat, can widely vary depending on customer’s requests. Project 22160 has capitalised on
experience gained in operations of both the Russian Coast Guards and foreign navies. The purpose of this project was to design a vessel with reasonable production and opera- tional costs, which would make a highly effective, sea-going multi- purpose ship capable of perform- ing a wide range of missions to be carried out within state borders and exclusive economic zones, such as
sions the ship can be fitted with two standard 40-feet container modules filled with weapons and equipment of various types rang- ing from strike missile systems (the Club-K missile system offered
by the Novator Design Bureau) to remotely operated underwater ve- hicles for mine detection and de- struction. Replaceable containers with various systems allow opti- mising both tactical scenarios that naval task forces can implement with such weapons, and their stor- age and maintenance costs. Moreover it is possible to fit
up the ship with automatic anti- aircraft artillery and/or missile/ artillery systems (of both Russian and foreign origin), landing boats for delivering amphibious assault groups, and environment/shelf monitoring equipment. It must be also reminded that
all ships of the Severnoye DB proj- ects can be completed with weap- on systems and equipment of both Russian and foreign origin. The Design Bureau has rich
experience of cooperation with foreign companies in the field of shipbuilding which allows it to quickly consider customer requests and render technical assistance in ship construction performed at do- mestic and foreign shipyards.
border defence, fighting piracy and environmental protection. The ship is armed with one 57-
mm (or 76-mm) Russian/foreign- made automatic gun, an anti-sabo- teur aids with a dipping sonar and two automatic grenade launchers, two 14.5-mm machine guns on pedestal mounts, Igla type por- table air defence system. It is also fitted with two high-speed (up to 65 km/h) high-seaworthiness (sea state of up to 3-4) rigid inflatable boats capable of carrying up to 10 persons each, and aid equipment for treating casualties of natural di- sasters and accidents. The ship can accommodate
one helicopter weighting up to 12 tonnes and/or four UAVs to extend the range of missions performed. The UAVs can be permanently based using a 12x12-m helo-deck, a stationary hangar, 40-tonne avia- tion fuel storage and a helicopter handling gear. The ship-based avi-

ation system can be effectively op- erated day and night in sea state of up to 4 inclusively. The ship is powered by a diesel
or a combined diesel-turbine pro- pulsion plant (the choice depends on requirements for full and patrol speeds) with joint operation of all engines at full speed and the pos- sibility to engage electric motors/ shaft generators at low and patrol speeds. Modern long-endurance diesel engines possess high fuel efficiency at patrol and cruising speeds (up to 18 knots inclusively during 70-75% of the total op- eration time) and employment of electrical motors helps to save die- sel engines’ life in disadvantageous modes of sustained motion at low and very low speeds (3-10 knots). At the same time the ship powered by the diesel engine can gain the full speed of up to 30 knots. The main machinery is configured to provide alternate or joint opera-
