Floating foothold: what is interesting about the large landing ship "Ivan Gren". A ship at a crossroads: the commissioning of the Ivan Gren large landing ship is not a dot, but an ellipsis ... Landing ship Ivan Gren of project 11711

BDK project 11711 are designed for landing, transportation of military equipment and other cargo. The internal volumes are sufficient to accommodate a battalion of marines with equipment attached to it. Developer - "Nevsky Design Bureau" (NPKB). Its specialists proudly note that the Ivan Gren is the first type of landing craft created in the history of modern Russia. The design was carried out at the turn of the century on the basis of modern technological solutions and a unified information database of design data, three-dimensional prototyping of the ship as a whole and all the main rooms and posts, landing devices and structures, the technological chain of information processing using the latest applied and specialized software packages. an export passport and can be offered for export, ”said Sergey Sergeevich Vlasov, general director of the NPKB, to the website of the Zvezda TV channel. Judging by the official catalog of the United Shipbuilding Corporation, we are talking about project 11711E with a total displacement of 6600 tons. Plant "Yantar" The Yantar Baltic shipbuilding plant is responsible for the production of Project 11711 ships. The head hull was laid down in 2004 and launched in May 2012. During construction, the drawings of "Ivan Gren" were finalized, reflecting the changes in the views of the leadership of the Russian Navy on the role and place of landing craft. Mooring trials of the ship began in autumn 2015. Then "Ivan Gren" was docked for painting the underwater part and other work. At the beginning of the next year, the hull underwent degaussing. Factory sea trials started last summer and, after the completion of the ship, resumed earlier this year. According to Eduard Aleksandrovich Efimov, general director of the shipyard Yantar, the company expects to hand over the Ivan Gren to the fleet by the end of this year. The ship has been improved and is currently preparing for the next phase of testing at sea. In the fall of 2014, a decision was made to build a second ship. The building of the BDK "Pyotr Morgunov" was laid down the summer before last. Launching is expected within the next few weeks, and commissioning is expected during 2018. The future of the program remains uncertain. Previously, plans were announced for a series of four to six ships, but they may be revised during the ongoing process of developing and adjusting a new version of the State Armaments Program (SAP). So far, SAP-2025 exists only in a project that needs to be approved by the country's top political leadership. The current conditions are conducive to an increase in the order for Project 11711 ships. The fact is that in the design of the Ivan Gren, the use of foreign components is minimized and, therefore, the construction of such vessels does not depend on "external factors".
Since 2009, Yantar has been undergoing a comprehensive reconstruction of production facilities, which should result in an increase in output by more than five times, while reducing construction time by half, while reducing the cost of a unit of production. Without placing a sufficient amount of state orders, efforts to modernize production will lose their meaning. During the Soviet period, Yantar built half a thousand civilian ships and more than 160 warships. Among them are large anti-submarine and landing ships, frigates and corvettes. In the new century, the Russian Navy received patrol ships created by local shipbuilders, made according to projects 11540 and 11356, and the latter were also exported to the Indian Republic. Giesserai” (Union Giesserei), from where in the second half of the 19th century, by order of the tsarist government, all-steel steamships and steam locomotives were supplied. Then the local plant was transferred to the firm "Schihau" (Schihau), which went down in history thanks to the construction for our fleet of the fastest (developing speed - 25 knots) for that time (1901) armored reconnaissance cruiser "Novik". Project Features It is believed that "Ivan Gren" is the development of the Soviet project 1171 "Tapir", according to which from 1964 to 1975. Kaliningrad shipbuilders assembled 14 hulls. Four of them have survived to this day. BOD "Nikolai Vilkov" remains part of the Pacific Fleet, "Saratov", "Orsk" and "Nikolai Filchenkov" - the Black Sea. In fact, project 1171 was a military version of a civilian dry cargo ship, distinguished by the presence of a tailgate, a dock chamber and a reinforced bow ramp (Ivan Gren has a bow and stern ramp). It should be noted that in 2004, Ukraine converted the BDK-104, which it inherited, into the Horlivka dry cargo ship. They are designed for landing amphibious assaults on an unequipped coast, and are capable of transporting various types of equipment, including tanks, with a total weight of one thousand tons. Having retained the main purpose, project 11711, however, is seriously different from 1171. Firstly, the total displacement has been increased by more than than two thousand tons. The length of the hull has increased by seven meters, the width - by almost a meter. If the “tapirs” have a small aft superstructure, then the “Ivan Gren” has a developed superstructure with five tiers in the bow and four in the stern. For old ships, the armament is limited to the ZIF-31B artillery mount of 57 mm caliber, and later buildings additionally received a pair of launchers installations of the Grad-M multiple launch rocket system. On the new ship, the armament has become, as it were, “more defensive”, and is represented by one AK-630M-2 “Duet” artillery mount (the record holder for the rate of fire among 30-mm machine guns is ten thousand rounds per minute!), A pair of AK-630M anti-aircraft guns (4-5 thousand rounds per minute each) and Sting machine guns. The maximum travel speed increased by one knot, up to 18, thanks to the main power plant from a pair of diesel engines 10D49 (16CHN26 / 26) with a capacity of 5200 horsepower produced by the Kolomensky Zavod . They are distinguished by a 16-cylinder V-shaped design and gas turbine supercharging. "Ivan Gren" is equipped with modern on-board systems, including the latest radio electronics. Much attention is paid to improving the living conditions of both the crew (one hundred people) and the marines (up to three hundred). For them, a gym, a dining room, cabins and cockpits are equipped on board. It is important that the ship has the ability to take on board modern armored vehicles, including main battle tanks weighing up to 60 tons, with a maximum number of up to thirteen pieces. If the number of marines transported is the same as for project 1171, the maximum value of the transported cargo has increased by one and a half times. Aviation armament Some sources note that Project 11711 BDK allegedly represents a replacement for the helicopter carriers built in France, but never transferred to Russia - the Mistral-type universal landing dock ships.
Such statements are a big stretch due to the huge difference in displacement (more than four times) and the size of the aviation group (fifteen times). At the same time, Ivan Gren is quite suitable as a carrier of the latest Ka-52K Katran helicopter. Moreover, it has a spacious deck hangar for storing aircraft. It is more correct to compare the new Russian BDK with the Chinese Type 072-III, Yuting-II class. They represent large tank landing craft, which are considered the main ones in the Navy of the People's Liberation Army of China.
With close dimensions and basic characteristics, our project is distinguished by the presence of a full-fledged helicopter hangar, which houses a pair of transport-combat Ka-29s or one Katran. Note that both types of rotorcraft took part in the air part of the July 30 parade. They flew over the decks of the BDK project 775, and the Minsk was in the ranks of the ships on the Neva, and the Alexander Shabalin followed in the wake column that passed through the sea channel near Kotlin Island. Since 2012, Project 775 large landing ships have been actively used to deliver goods to the Syrian Arab Republic, supplying the Russian group and government troops stationed there. Ships of three fleets participate in the “Syrian Express”, delivering mainly weapons and ammunition to the Tartus naval base, which are then used against illegal gangs. Although Project 775 large landing ships cope with their task, they operate at the limit of their technical capabilities, remnants of motor resources. Replenishment of the "Syrian Express" with much more modern ships of project 11711, which have higher carrying capacity, speed and resource, will improve the situation with the supply of forces operating on the anti-terrorist front.

The large landing ship "Ivan Gren" of project 11711 (according to NATO codification Ivan Gren) will soon become the most modern landing ship in the Russian fleet. BDK "Ivan Gren" is designed for landing, transportation of military equipment, as well as various equipment and cargo. In total, two ships of this project were laid down for the Russian Navy. The lead ship "Ivan Gren" is undergoing the final stage of state tests, the second large landing craft "Pyotr Morgunov" is being prepared for launching. The Russian military abandoned the further construction of ships of this project in favor of creating even larger and more spacious ships of this class.

At the end of December 2017, Eduard Efimov, General Director of the Yantar Baltic Shipbuilding Plant, told reporters that the large landing ship Ivan Gren had reached the final stage of state trials. Shortly before this, the newest Russian ship conducted its first firing and tested naval artillery in the Baltic Sea. It is worth noting that the Ivan Gren is a ship with a very difficult fate, it was laid down in Kaliningrad on December 23, 2004, but was launched only on May 18, 2012 and has not yet been included in the fleet. At the initial stage, the assembly of the ship was seriously complicated by unstable funding and problems at the enterprise itself.

At the same time, the new ship in the fleet is no doubt waiting. Entering it into the fleet will significantly expand the capabilities of the Russian Navy at sea and in remote regions of the planet. The landing ship of the Ivan Gren ocean zone of project 11711 will be able to take on board up to 300 marines, as well as 13 main battle tanks (weighing up to 60 tons) or a choice of up to 36 armored personnel carriers / infantry fighting vehicles, military equipment is located on the tank deck. Also on board the ship there is a covered hangar and a take-off area for helicopters. It can take on board up to two Ka-29 transport and combat helicopters, or Ka-27 search and rescue helicopters. If necessary, the Ka-52K Katran attack helicopter can also be placed on board.

Project 11711 large landing ships are a further development of the Soviet BDK project 1171 Tapir. The design of the ships of the new project was carried out by the Nevsky Design Bureau. The hull of the Project 1171 ships was not taken as a basis by chance; it has proven itself well over decades of service in the Soviet and then Russian fleet. At the same time, most of the structures within the framework of the new project have undergone significant changes. The superstructures and interiors of the landing ship were mainly redesigned. During the construction of the Ivan Gren large landing ship, the most modern technologies were used, in particular, aimed at reducing visibility through the use of modern technical solutions and materials. In addition, increased attention was paid to the conditions for the accommodation of the ship's crew and paratroopers. A gym, a dining room, as well as more comfortable cockpits and cabins appeared on board the BDK.

The loading of military equipment onto the ship can be carried out either independently on ramps or with the help of cranes. Loading of cargo and equipment into the troop compartment can be carried out through a four-leaf cargo hatch located in the upper deck using a crane with a lifting capacity of 16 tons. For loading on board motor boats, boats and equipment, there are also two boat cranes on board. Among other things, the ship's cargo hatch can be used for ventilation, removing exhaust gases from operating equipment from the deck space (troop compartment). Ventilation of the troop compartment is very important, as it allows the transported equipment to warm up the engines, which is very important in conditions of low air temperatures. Exhaust gases from idling vehicles quickly fill the landing hold, so ventilation through the upper cargo hatch is a must, thanks to this, the paratroopers will not be poisoned by exhaust gases.

The main feature or “chip” of the Project 11711 ships is the so-called non-contact method of landing troops on an unequipped coast. To do this, engineering pontoons can be pushed into the water from the open bow flaps, which, when coupled, form a bridge to the shore. This pontoon bridge docks with the shore, on which the landing is made, after which it is used to ferry heavy equipment and marines. This landing scheme allows you to maintain a distance between the BDK and the shore, seriously reducing the risk of running aground.

The capabilities of the Ivan Gren large landing ship allow it to transport tanks, infantry fighting vehicles, armored personnel carriers, army trucks or towed artillery over a distance of up to 3.5 thousand nautical miles (at a speed of 16 knots) by sea. Military equipment is transported on the so-called tank deck. Equipment can be loaded on board in different ways: by a deck or gantry crane; it can also drive on board the vessel under its own power through the stern ramp. In addition to military equipment, the BDK can carry various cargoes, including standard 20-foot sea containers. In standard 20-foot shipping containers, among other things, the Club-K missile system, which is a modification of the Caliber missile system, can also be placed. At the same time, it is unlikely that any missile systems will appear on board the Ivan Gren large landing ship, since countering enemy ships is not included in its direct tasks.

Light floating armored personnel carriers, infantry fighting vehicles and infantry fighting vehicles can be launched into the sea directly from the stern and bow of the ship, they are able to get to the shore on their own. Landing is possible with sea waves up to 4 points. Due to the range of the Ivan Gren, it has the ability to remotely land, it is able to patrol a certain region for a month, the autonomy of navigation is exactly 30 days.

The total displacement of the landing ship is 5,000 tons, length - 120 meters, width - 16.5 meters, draft - 3.6 meters. The heart of the BDK "Ivan Gren" are two 16-cylinder V-shaped diesel engines 10D49 with a gas turbine supercharged power of 5200 hp. The capabilities of the power plant allow you to accelerate the ship to a maximum speed of 18 knots. The crew of the ship consists of 100 people. The most modern BDKs in the Russian fleet before the advent of Project 11711 ships were Polish-built BDKs of Project 755. Ivan Gren surpasses them in displacement - 5,000 tons versus 4,080 tons for Project 755 ships, in addition, the new Russian landing ship is 8 meters longer, 1.5 meters wider and 1.3 meters deeper in the water. Accordingly, its landing capabilities are higher.

As part of the work on the project and the construction of the ship, its armament has undergone changes. According to the initial design, one AK-176M 76-mm artillery mount, two Broadsword anti-aircraft artillery systems and two launchers of the A-215 Grad-M multiple launch rocket system were to appear on board the BDK. However, due to the fact that the concept of using the BDK project 11711 has changed, as well as to save money and time to build the ship in 2010, it was decided to change the composition of weapons, which today are purely defensive in nature.

The armament of the Ivan Gren BDK is represented by one AK-630M-2 two-automatic shipborne 30-mm automatic artillery mount, two AK-630 mounts with a 5P-10-03 Laska radar fire control system, two 14.5-mm MPTU mounts " Sting", as well as a complex of fired passive interference KT-308-04 "Prosvet-M", this complex protects the ship from enemy missiles.

AK-630M-2 "Duet" is a modern two-automatic 30-mm automatic artillery mount, which provides a huge rate of fire - up to 10,000 rounds per minute. Its main purpose is to provide anti-missile defense of the Navy ships in the near zone. First of all, it is designed to destroy anti-ship missiles and other types of guided missiles. Also, the installation can solve the problem of hitting enemy aircraft, helicopters and UAVs, small-sized surface and coastal targets. The effective firing range is 4000 meters.

The AK-630M-2 and AK-630 installations are built according to the scheme of multi-barreled weapons (6 barrels each) with a rotating barrel block (the so-called Gatling scheme). The automation of Russian installations of this type is powered by the energy of powder gases and, unlike foreign counterparts (Phalanx CIWS and Goalkeeper), does not require external energy sources to rotate the barrel assembly. Installed on the Ivan Gren landing ship, the AK-630M-2 Duet installation became a further modernization of the AK-630M1-2 complex, from which it visually differs in a tower that received less radar visibility.

In addition to rapid-fire artillery weapons, there are two large-caliber machine guns on board. This MPTU "Sting" - 14.5-mm naval pedestal machine gun mounts, which are designed to combat air, surface and coastal lightly armored targets. Large-caliber machine guns can effectively hit lightly armored targets at ranges up to 2,000 meters and 1,500 meters in height. For firing at air, surface and coastal targets, cartridges with an armor-piercing incendiary bullet B-32, an armor-piercing tracer bullet BZT, and an instantaneous incendiary bullet MDZ are used.

On the Internet and various media, one could come across allegations that the new Russian BDK project 11711 is supposedly a kind of replacement for the Mistral-type universal landing dock ships built in France, but never transferred to the Russian Federation, but this is absolutely false. Firstly, the construction of the Ivan Gren large landing ship began long before the decision of the Ministry of Defense to purchase Mistrals in France, and secondly, it is difficult to compare the ships even in terms of their technical capabilities, mainly in size. It is incorrect to compare them because of the huge difference in displacement (more than 4 times), as well as the size of the aviation group (Mistrals can carry up to 16 light helicopters on board).

It is more correct to compare the new Russian BDK project 11711 with the Chinese Type 072-III ships (Yuting-II class), which are large tank landing craft, which are the main landing craft in the PRC navy. With similar characteristics and dimensions, the Russian project is favorably distinguished by the presence of a full-fledged helicopter hangar on board.

Despite the fact that Russian sailors are not interested in the further acquisition of the BDK project 11711 (information about this appeared in 2015), abandoning them in favor of larger ships of the new generation, it is too early to put an end to the future prospects of the BDK project 11711. Currently, the ship already has an export appearance passport, so it can be promoted by Russia for export. This was reported by the Zvezda TV channel with reference to Sergei Vlasov, who is the general director of the Nevsky Design Bureau. Judging by the official catalog of the United Shipbuilding Corporation (USC), we are talking about project 11711E, which received a displacement increased to 6600 tons.

Larger landing craft that may appear in the Russian fleet in the future include ships of the Priboy project. As part of the Army-2015 forum, a mock-up of universal landing ships of the Surf project with a displacement of more than 14,000 tons and a capacity of up to 500 paratroopers, 20-30 tanks or 60 units of various military equipment was presented for the first time. Among other things, these ships will be able to take on board up to 8 Ka-27 or Ka-52K helicopters.

The Russian Navy has been replenished with a large landing ship (BDK) "Ivan Gren". The solemn ceremony of entering the ship into the Russian Navy was held at the Yantar plant in Kaliningrad. The ship will soon be at the disposal of the Northern Fleet. "Ivan Gren" became the largest landing ship in the country. The ship can transport an entire battalion of marines with tanks and armored vehicles to the theater of operations. About the combat capabilities of the latest Russian BDK - in the material RT.

At the shipyard "Yantar" in Kaliningrad, a solemn ceremony of raising the flag of St. Andrew on a large landing ship (BDK) of project 11711 took place. The ship is expected to be handed over in the near future.

The ceremony was attended by representatives of the command of the Baltic Fleet, Deputy Commander-in-Chief of the Russian Navy for armaments Vice Admiral Viktor Bursuk, top managers of the United Shipbuilding Corporation (USC).

The brainchild of "Yantar"

"Ivan Gren" - the lead ship of project 11711 developed by JSC "Nevsky Design Bureau". At the moment, this is the largest BDK of the Russian Navy. The displacement of the giant is 5 thousand tons, the length is 120 m, the width is 16.5 m, the draft is 3.6 m.

“Project 11711 is significantly different from its Soviet predecessors. "Gren" and "Morgunov" have a large displacement and capacity. Also, new diesel engines, on-board electronics, and more powerful hydraulics are installed on the Russian BDKs. Our fleet has a huge need for such ships, ”retired colonel Mikhail Timoshenko said in an interview with RT.

The main feature of project 11711 is the ability to transfer a battalion of marines (about 400 people) along with equipment. "Ivan Gren" can take on board 13 tanks or more than 30 armored vehicles (armored personnel carriers and infantry fighting vehicles). A transport and combat helicopter and two multi-purpose Ka-27s are placed on the deck of the BDK.

The range of the latest ship is 4,000 miles (about 6,000 km). According to the Ministry of Defense, during the tests, the Ivan Gren showed "good seaworthiness and the flawless operation of all life support systems."

The armament of the BDK includes the Grad-M multiple launch rocket system, the ZIF-31B 57-mm twin anti-aircraft artillery mount, two AK-630 30-mm six-barreled automatic guns and one modernized AK-630M-2 Duet gun mount with a radar control system fire 5P-10-03.

The design of "Ivan Gren" began in 1998. The ship was laid down in 2004, but its construction was delayed due to lack of finances and constant changes in the terms of reference that the customer made.

“Initially, the terms of reference were issued for a ship that would navigate inland waterways - rivers and canals. According to the task, its width, height and draft were laid. Then we had to remake it into a naval ship - change the height of the superstructure and make some other changes to the project, ”Sergey Vlasov, general director of the Nevsky Design Bureau, explained in an interview with TASS.

As a result, the BDK was launched in May 2012. In October 2015, mooring tests of the ship started, and later - sea trials. From November 2017 to May 2018 was held.

According to media reports, the military identified problems with the ship's reverse gear. At the end of December 2017, state tests were suspended, and on April 3, after the elimination of shortcomings, they were resumed. On June 2, Yantar signed an acceptance certificate for state tests with the Ministry of Defense.

The need for an update

The renewal of the amphibious fleet is one of the priorities of the Russian Navy. In June 2015, the Commander-in-Chief of the Navy, Admiral Viktor Chirkov (since 2016 this position has been held by Vladimir Korolev), stated that the composition of the landing craft would be almost completely replaced by 2050.

“The need to update the composition of landing ships in all fleets is long overdue. This is taken into account by the shipbuilding program. The High Command has developed and is developing technical requirements ... for most landing ship projects - from a landing boat to a large landing ship, ”Chirkov said.

On May 25, 2017, Deputy Defense Minister Yuri Borisov (now Deputy Prime Minister) announced that the State Armament Program until 2025-2027 included the construction of two universal landing ships (UDC). Later, the United Shipbuilding Corporation clarified that we are talking about helicopter carriers of the Priboy type.

On June 18, 2018, the TASS agency reported that JSC Northern Design Bureau, located in St. Petersburg, is working on the creation of a fundamentally new BDK with a displacement of about 8 thousand tons. As specified in the USC, engineers are developing a sketch of the future ship.

The Nevskoye Design Bureau is ready to offer the Ministry of Defense a modernized version of project 11711. The updated version of the BDK will improve "habitability" and driving performance. As Vlasov said earlier, the company is able to meet any customer requirements.

The Ivan Gren is an excellent ship capable of performing the tasks for which it was designed, but it cannot be called fundamentally new, as it was designed for too long. Therefore, we hear statements about the need to modernize project 11711. Considering that there were only problems with the lead ship, the rest of the BDK will be built much faster, ”Tymoshenko concluded.

On August 31, 2016, the lead ship of project 11711 "Ivan Gren" completed the testing of the aviation complex in the Gulf of Finland and on September 2 returned to the delivery base in Baltiysk, where the preparation of the ship for the next exit to the sea began.
While the ship was at anchorage, a group of journalists, thanks to the active assistance of the press service of the plant and the press service of the Baltic Fleet, managed to visit the ship and make a detailed photo report about the new ship.

The ship was laid down on December 23, 2004 in the city of Kaliningrad at the Yantar Baltic Shipbuilding Plant under serial number 01301.

The project was developed in the traditional designer of large landing ships - JSC "Nevskoye Design Bureau" in St. Petersburg in the period from 1988 to 2004 to replace the obsolete BDK projects 775 and 1171. The bureau is headed by General Director and General Designer Viglin A.O., and the chief designer of the project is Suvorov V.N. The ship is intended for landing on an unequipped coast, as well as for the transfer of cargo by sea in the near and far ocean zone and participation in peacekeeping operations.

The BDK is able to implement the following methods of disembarking equipment: directly onto an unequipped shore using a bow landing device or afloat both through the bow and stern ramps or using a Ka-29 assault and transport helicopter. The beam crane, located between the five-tier bow and four-tier aft superstructures, allows you to unload light equipment and cargo on the quay wall or on floating landing craft under the side of the ship. The innovation is a new non-contact method, which involves the use of engineering pontoons, similar to those used by ground forces when forcing water barriers. A floating bridge is formed from several pontoons, along which heavy and light equipment can move and land directly on the shore, which has a slope of less than 3 degrees. This method has long been used abroad, but in the domestic fleet it is used for the first time. Also, an innovation for the domestic fleet is the possibility of transporting 20-foot sea containers with any type of cargo, made according to international standards, on the upper deck and unloading them onto watercraft or a mooring wall.

The ship is two-shaft, two-deck, with a forecastle, poop, aft engine room, two superstructures and a through, from bow to stern, landing hold, which accommodates mobile military equipment. The hull and superstructure are steel. Since the ship is designed for long-term patrols with landing troops on board, the comfortable placement of the landing party is of no small importance. Multi-seat cabins with three-tier berths, a sports hall, comfortable showers and washbasins are provided for landing. A special ventilation system is provided to ensure warming up of the engines of equipment located on the lower deck. A hangar for 1 Ka-29 helicopter is provided in the aft superstructure, but due to the fact that the hangar design has a retractable part towards the helipad, it is possible to base two helicopters, but the use of the second one while the first one is in the air will be difficult.

The unique appearance of the ship is given by a developed tank with a large bend and elevation above the waterline, the design and dimensions of which are due to the use of engineering pontoons for a new non-contact landing method, as well as the use of a bulb-type hydrodynamic nose fairing in the underwater part of the ship. The draft of the ship without cargo is 4.6 m at the bow and 5.0 m at the stern.

In the process of completing the construction of the ship, the project was adjusted 3 times in terms of changing the composition of weapons, electronic equipment and changing the performance characteristics, and due to the short supply of documentation and counterparty equipment, the deadlines for the order were postponed more than once. According to the original project, it was planned to arm the ship with a new 100-mm A-190M artillery system and two Broadsword anti-aircraft artillery systems, two launchers of the A-215 Grad-M multiple launch rocket system were provided for landing fire support. As a result, due to the requirement put forward already in the process of construction to save budget funds and reduce construction time, the armament was significantly reduced and the task of providing fire support to the landing force from the ship was removed. The installed weapons include two artillery systems of a similar purpose and the same caliber - a bow 30-mm gun mount AK-630M-2 "Duet" and two aft 30-mm gun mounts AK-630M with a fire control system 5P-10-03 "Laska". Such a composition of weapons is not typical for other ships of the Russian Navy and is rather a compromise between the necessity and capabilities of the state defense order. Two 14.5-mm heavy machine guns MTPU "Sting" provided by the project and portable MANPADS were not installed during sea trials.

"Ivan Gren" is able to take on board 13 main battle tanks, which are in service with the Russian Armed Forces, or 36 units of tracked or wheeled military equipment in the dimensions of an infantry fighting vehicle, as well as 300-380 troops with weapons, ammunition and ammunition. The total mass of various cargoes taken on board the ship is up to 1500 tons.

The main power plant consists of two DRRA-3700 diesel-reverse-gear units based on a 10D49 diesel engine with a turbocharging control system SUTN-10060, working on a fixed-pitch propeller, providing the ship with a speed of up to 18 knots. The effective power of one unit is 5200 hp. Each engine room has two auxiliary diesel generators ADG-1000NK as part of the diesel engine 8DM-21S. One diesel generator provides all the electricity needs in standby mode, two diesel generators provide guaranteed power in combat mode.

On May 18, 2012, the ship was launched, and a decision was announced to build a series of six such ships, but after the laying of the second ship, called Pyotr Morgunov, the series was reduced to two units. The decision on the further construction of similar ships will be made after comprehensive tests of the lead one. Also in 2003, the development of an export version of the BDK was announced - project 11711E.

On June 25, 2016, the large landing ship "Ivan Gren" went to sea for the first time as part of factory sea trials in the Baltic Sea ranges. And on August 15, 2016, Ivan Gren anchored in the waters of the Gulf of Finland to board the Ka-29 helicopter and test the aviation complex. Due to the breakdown of the material part of the helicopter, the tests began only on August 23; made 24 deck landings.

During the test program in the Gulf of Finland, the ship had to perform the first rescue operation in its life. On August 29, at around 15:00, a small-sized private boat "Shved" passing by the ship with registration number Р7246ЛХ gave a distress signal and requested help. The boat was traveling from Finland to St. Petersburg and got into a storm of 3-4 points with a wind of up to 12 m per second. Unexpectedly for the captain of the vessel, the anchor was knocked out of the anchor hawse by waves and the entire anchor-chain was thrown overboard, which had to be cut due to a malfunction of the capstan device. Passengers on board, including two children, were severely swayed. The boat was poorly controlled on a wave, but had a course and communication. The captain of the boat asked the commander to lift the boat on board, but since he did not have a special launching device, there was a threat to break the boat on board during heavy roughness when lifting. Given the current situation, the commander of the ship decided to cover the boat from the waves and, putting it in the wake, escorted it to a safe area, maintaining constant communication on VHF. Two miles from the shallow coast of Zelenogorsk, the BDK handed over the victim to the forces of the Ministry of Emergency Situations, who moored the boat in the waters of the Zelenogorsk yacht club at about 20:00.

On September 2, the ship arrived in Kaliningrad to eliminate the identified remarks. But, unfortunately, the expected entry of the ship into the Navy this year may not take place. Measurements of the levels of physical fields have shown that the currents created in the demagnetizing windings do not provide the values of the electromagnetic field stated in the terms of reference. This is due to the erroneous choice of brand and section of current-carrying cables. To replace them, it will be necessary to put the ship in a dry dock and carry out complex hull work.
