THE MAIN DIRECTIONS OF THE DEVELOPMENT AND THE FEATURES OF THE PERSPECTIVE SHIPS

The new purpose and the tasks of the navy, the general trend towards reducing the fleets and the fleets' infrastructure, mentioned above, as well as the reduced budgetary defense allocations made it necessary to develop new approach to the features of the future ships. We mean the ships which will come in 2010-2015, because due to the complicated nature of a ship it takes at least 10 - 15 years between the ship's concept and manufacturing.

The development of the strategic submarine missile carriers will continue within the frameworks of the international agreements, where an important role is given to the just ratified American-Russian agreement on limiting the strategic attack potentials, signed by the Presidents in 2002, under which each party determines itself the composition and the structure of its strategic attack arms based on the limited total number of warheads. Earlier agreements on the strategic attack arms restricted the number of the newly developed complexes, their carriers (including missile carriers), the number of the missiles and the blocks on the missiles. Keeping in mind the general tendency of reducing nuclear arms and developing the high precision cruise missiles with non-nuclear charges, in 20-25 years the nature of such submarines may be considerably changed.

Multi role nuclear submarines will develop becoming multi functional and universal. The main criteria in the development will remain reducing the noise level, improving the hydro acoustic weapons and reducing the level of other fields.

Utilizing the high precision cruise missiles with non-nuclear charges on such submarines will attribute the role of the strategic deterrence weapon to this class of subs.

Only five nations have multi role nuclear subs, whereas 43 nations have diesel-electric subs. Their total number is 380. The development of this class of subs, especially "coastal" subs of limited (as a rule 1000 tons) deadweight will go in the following directions.

increasing the power and the suddenness of the strike due to the increased number of combat ready weapons;

increasing the submarine speed aimed at intercepting the surface warships and transports within the vicinity of own coastline to ensure preventive strikes;

increasing the submarine endurance;

reducing the physical fields to the minimal level, first of all the fields of the electro magnetic group, aimed at minimal visibility when on patrol;

complexly automating the control systems of the ships and reducing crews.

Anaerobic power stations, especially single units, will make a great impact to the development of this class of subs.

The tasks of the navy provide for a certain composition of the general purpose ships, which includes an aircraft carrier, multi role ocean ship to protect the aircraft carrier and conduct own missions (destroyer), universal ship of the sea zone (frigate), short range ship (corvette) and mine sweeper.

Aircraft carrier can ensure air superiority for the long term campaigns as well as the organization, control and sustainability of different armed groups in a conflict area. Such ships are unique and expensive; therefore they will be made by a very limited number of nations. This is the most conservative type of a ship, and it will develop in the traditional direction.

The multi role ocean ship, having the characteristics of a torpedo carrier, anti sub ship and missile-artillery ship (destroyer), will have the displacement of up to 10 000 tons, the speed of 28-30 knots and the endurance of up to 10 000 miles at 16-17 knots speed. The type of the main power station is gas turbine with fully electricity based movement.

The destroyer will have a complex of missiles with universal vertical launching systems to use high precision missiles against ground targets, missiles against surface and submarine targets, air defense missiles of far, medium and small range targets as well as a universal artillery unit with high precision controlled shells against ground and surface targets. The ship will have one or two helicopters.

The radio electronic means of a destroyer will consist of the universal unit of detecting and targeting, a complex of radio electronic counter measures, a hydro acoustic complex for detecting subs, anchor and bottom mines, anti diversion means.

The universal ship of the sea zone (frigate) will have the displacement of about 5000 tons. Even now there are prerequisites to provide absolutely the same complex of weapons to the destroyer and the frigate with the only difference in the number of spare charges. At the same time such ship, having smaller displacement than the destroyer will be much cheaper. For most nations frigates will be the main battle ship.

The last ship in the surface list is corvette with the displacement of up to 2000 tons. It is supposed to conduct short range and coastal operations as well as the functions of the border guard.

A large role is given to the anti mine ship, which will have self propelled complex for detecting and destroying the mines ahead of the ship.

Military shipbuilding has been always based on the new technologies. During the past years the development of the ships has been based on the implementation of the new solutions of the traditional shipbuilding subjects - hydromechanics, strength of materials, (electric) energy. A bit later the main priority was given to the reduction of physical fields (acoustic, electromagnetic, radiolocation, heat, radiation etc.). Considerable results have been reached in all the above sectors.

The development of the shipbuilding in the past 20 years has been characterized by the degree of using electronic systems. During a historically short period the shipbuilders have passed the way from automated ships' rudders and some automated weapons to complicated automatic systems of combat control (ASBU), automatic control of the ships' power stations, equipment and movement. A fully integrated system of combat control of a sub is being developed. The works aimed at automating the surface ships are under way. The modern automated ship controls have high degree of reliability, high survival rate, big volume and high rate of signal processing.

The multi role nature of the large and middle warships as well as the complicated nature of the marine operations excludes the suggestion to make the ships automatic even in the remote future. Therefore the development of the automation of such ships should be based on further integrating separate functional systems, extending their intellectual level and the number of the instruments that can be used. The most perspective direction of automating the ship and introducing robots is ensuring the viability during combat or operational damages, as well as servicing potentially dangerous units and systems.

Today the tendency of transferring the achievements of the civil shipbuilding to the military sphere is the most important in the world's military shipbuilding. The civil tonnage is 140-150 times bigger than the military one, civil fleet is operated much more intensively, it has much higher safety standards and tough competition between civil ships in the market All this led to the reconsideration of the standards of the military shipbuilding by the main maritime powers from the point of view of benefiting from the civil experience. The leading foreign classification institutions that provide the design rules for the civil ships, started developing the design rules for battle ships. For example, the English Lloyd has issued the first version of such rules. Own rules to some ships' classes have been developed by the Italian Register, Norwegian Veritas and the American Bureau of Shipping.

Types of Boat Hulls

	Flat bottom boat - These boats are generally less expensive to build and have a shallow draft (the part of the boat that's under the water). They can get up on plane easily but unless the water is very calm they tend to give a rough ride because of the flat bottom pounding on each wave. They also tend to be less stable and require careful balancing of cargo and crew. Examples of flat bottom boats might be Jon boats, small utility boats, and some high speed runabouts.
	V-bottom boat - The V-bottom tends to have a sharper entry into the water which provides for a smoother ride in rough water. They do, however, require more power to achieve the same speed. Many runabouts use the V-bottom design.
	Round bottom boat - These move easily through the water, especially at slow speeds. They do, however, tend to roll unless they are outfitted with a deep keel or stabilizers. Many trawlers, canoes and sailboats have round bottoms.
	Multi-hull boat - Catamarans, trimarans, pontoon boats and some house boats use a multi-hull design. The wide stance provides greater stability. Each of the hulls may carry any of the above bottom designs.
