Over the past several decades, as part of the Soviet and Russian naval fleet landing boats and hovercraft serve. The largest representatives of this class are the Project 12322 Zubr small landing ships. They are distinguished by high performance characteristics, capacity and the ability to deliver and land troops on different coasts. The high technical and combat potential of such MDKVPs is used by our fleet, and has also attracted interest from foreign navies.
large series
Project “12322” or “Bison” has been developed since the late seventies by the Leningrad Central Marine Design Bureau “Almaz”. It is based on developments from previous small landing hovercraft, as well as a number of new ideas and components. The design took several years, and in 1983 construction began on the lead ship of a new type.
“Bison” were planned to be built for the Baltic and Black Sea fleets. The ships for the Red Banner Baltic Fleet were to be assembled by the Primorsky Shipyard (now Almaz, St. Petersburg), and the hulls built at the More shipyard in Feodosia were intended for the KChF. In total, it was planned to put into operation 17 new MDKVP, but Perestroika and the collapse of the USSR led to a serious revision of these plans.
By the time the country collapsed, six ships had been built in Leningrad, and three more were under construction. Two of them were then dismantled on the slipway. Three “Black Sea” ships and unfinished orders for the “Sea” went to Ukraine. Subsequently, attempts were made to complete the construction of the ships and put them into operation. In addition, Ukrainian shipbuilders proposed their own version of the project with a different set of equipment.

As a result of all the events of recent decades, only two Zubrs remained in the Russian Navy - Evgeniy Kocheshkov and Mordovia, accepted into service in 1990-91. In the late nineties, Ukraine began to abandon the existing MDKVP, and disposed of several pennants. At the beginning of the 728s, Greece acquired four ships: three were completed and transferred by Russia, the fourth came from Ukraine. In the tenth years, Ukrainian industry was able to sell two modified Zubrs to China. To date, the PRC has independently built two more similar ships, designated “Type XNUMX”.
Technical features
The Zubr project proposed the construction of a hovercraft capable of transporting and landing personnel, equipment and weapons on the coast. The total length of such a ship is approx. 57 m with a width of 25,6 m. Displacement - 555 tons. Crew includes 27 people.
The hull structures of the Zubr are welded and made of aluminum-magnesium alloy, resistant to corrosion. The hull consists of a lower flat pontoon, on which the air cushion fence is attached, and a superstructure. The superstructure is divided into three longitudinal compartments: the central one performs the functions tank deck and has a bow ramp, and the side ones accommodate the main units and mechanisms. On top of the superstructure are the wheelhouse and propulsion engines in ring channels.
The ship is equipped with five DP71 gas turbine engines with a power of 10 thousand hp each. Two engines drive the NO-10 blower units to create an air cushion. The other three perform the functions of marching ones: they are located in the stern on columns and rotate propellers in ring channels. Electricity is generated by two gas turbine generators of 100 kW each.

In its original configuration, the Zubr had advanced electronic weapons. On board there were several radars for various purposes, navigation aids, an electronic warfare system, etc. With the help of these systems, the navigation of the ship, the use of weapons, etc. are ensured. In foreign projects, the composition of the electronics changed, but without fundamental restructuring.
To support the landing, MDKVP pr. 12322 has a pair of A-22 multiple launch rocket systems. Each launcher carries 22 140 mm caliber projectiles and is stowed under the deck when in motion. There are also two AK-630 assault rifles. Barrel and missile weapons are controlled remotely. In addition, the crew has several MANPADS at its disposal.
Driving advantages
The high performance and combat characteristics of the Zubr-class ships are due, first of all, to their unusual method of movement. The air cushion allows for high speed and other advantages. In terms of the combination of propulsion parameters and corresponding capabilities, MDKVP Project 12322 is superior to ships of traditional design.
The air cushion lifts the ship above the surface and sharply reduces the resistance of the environment. Thanks to this, the Zubr is capable of reaching speeds of up to 63 knots - twice as fast as ships with a displacement hull. Economic speed is also at a record level - 55 knots. It provides a range of 300 nautical miles.

Depending on the operating mode of the superchargers, the lower elements of the ship rise above the surface to a height of up to 300-500 mm. This feature gives the MDCV amphibious capabilities. The “bison” can move on water or on ice, as well as climb onto a gentle bank and move along a flat coast. According to the calculations of the project developers, the ship is capable of landing troops on 70% of the coastline of the world's seas and oceans.
High mobility and maneuverability reduces risks for the ship. Thus, when approaching the shore, it can actively maneuver to escape fire. The landing takes no more than a few minutes, after which the ship returns to the water and leaves the danger zone. While on the shore, the MDKVP is capable of moving through trenches and some other obstacles, incl. mines.
Landing potential
MDKVP pr. 12322 is intended for the transportation of personnel, weapons, equipment or other cargo, as well as for their landing directly on an unprepared coast. The technical characteristics and layout of the ship make it possible to effectively solve such problems.
“Zubr” can transport up to 150 tons of cargo inside the hull. There are also cabins for 140 people. The ship's standard loadouts are 3 main tanks; 8 infantry fighting vehicles with crew and troops; 10 armored personnel carriers with people, etc. The tank deck can be used to accommodate and transport personnel. In this case, the ship contains approx. 500 people

Landing of people and equipment is carried out directly on land. The ship can go ashore and lower the ramp to the ground. The small slope and large ramp width simplify and speed up the descent, allowing personnel to begin combat missions faster and with less risk.
The ship can suppress enemy defenses until the moment of landing and support the landing with fire, for which it carries several cannon and rocket artillery systems. Within a radius of 4,5 km, A-22 MLRS are used. Each installation carries 22 high-explosive fragmentation projectiles and has ammunition for two additional salvos. 30-mm rapid-fire AK-630 guns are also used in the near zone.
The Zubr's weapons allow it to hit manpower, unprotected and lightly armored vehicles. Tanks or fortifications suffer serious damage, including loss of combat effectiveness. With the help of such fire support, the landing force can land, deploy its weapons and independently fight the enemy.
Not obsolete
The project of the small landing hovercraft 12322 "Zubr" was developed 40 years ago, and construction of the lead ship began at the same time. The two pennants of this type remaining in the Russian Navy recently celebrated their 30th anniversary. In general, the Zubr project is not new, but it cannot be called obsolete.

Despite their considerable age, the Zubrs retain high tactical and technical characteristics and have all the necessary capabilities. They are capable of quickly delivering troops to the shore and landing them, providing the necessary fire support. At the same time, the air cushion reduces the requirements for the landing area and gives the ship the broadest combat capabilities.
In terms of performance and other characteristics, the MDKVP Project 12322 is superior to landing ships and boats of a number of other classes. They are inferior only to large and versatile landing ships, but only in terms of carrying capacity and due to the lack of the ability to carry a helicopter.
Seeing the potential of the Zubr, the Soviet Navy at one time ordered the construction of almost two dozen such ships for the Baltic and Black Sea fleets. There are currently only two pennants in service, but the reasons for the reduction of such a fleet are not related to the ships themselves. “Bison” have repeatedly shown their best side and have given no reason to doubt their necessity.
It is noteworthy that the “12322” project and its variants are still of interest from the point of view of operation and application. Thus, the Russian Navy promptly maintains and repairs its ships. At the beginning of the XNUMXs, Greece acquired several Bisons, and China is right now building such ships for its Navy.
All this shows that in project 12322 “Zubr” the right ideas and solutions were proposed and successfully implemented, which made it possible to obtain the required level of tactical and technical characteristics and operational capabilities. The resulting ships remain relevant and unique even several decades after the project was developed. And it is obvious that the inherent technical and modernization potential has not yet been exhausted and will continue to be used.
