Press Service of the Western Military District
MOSCOW, December 29 - RIA Novosti, Andrey Stanavov. Three hundred heavily armed Marines, 13 main battle tanks or - to choose from - about 40 armored personnel carriers / infantry fighting vehicles, as well as two transport helicopters. Such a mini-army can easily fit on board a large ocean-going landing ship (BDK) of project 11711 "Ivan Gren". Until the end of the year, the St. Andrew's flag will be raised on it, and the Gren will officially become part of the Northern Fleet. This "paratrooper" is the first Russian ship of this class, capable of providing disembarkation of people and heavy equipment without contact with the shore. About what he surpassed his predecessors and what place he will take in the fleet - in the material of RIA Novosti.
Marines with delivery
Except for the flotilla of small and medium-sized amphibious ships, then only the BDK today in the Navy includes about two dozen. These are ships of Soviet projects 775 (of the Caesar Kunikov type) and 1171 (of the Nikolai Filchenkov type). If the former are still relatively young, then the age of the latter is already approaching the respectable one. For example, Saratov was launched in 1964. And although the ships are regularly repaired, it is obvious that very soon they will need replacement. "Ivan Gren" - a direct descendant of the large landing craft project 1171 "Tapir", or rather, its development. Even in basic characteristics, they are similar: the grandfather, which looks like a dry cargo ship, also has a solid displacement and can carry 300 marines and two dozen tanks.
The flat-bottomed ships of the Polish-built project 755, which now form the basis of the BDK fleet, are inferior to the Ivan Gren in size and capacity. For comparison: the total displacement of the new ship is 5000 tons against 4080 for the Polish "brother". In addition, it is eight meters longer, one and a half meters wider and 1.3 meters deeper in the water. If "Caesar Kunikov" can accommodate 190 marines and ten tanks (or 24 armored personnel carriers), then "Gren" - 300 and 13, respectively. The ships of the 775th project were built in two series, and the third was planned - specifically for the transportation of T-80 gas turbine tanks. It is noteworthy that the lead BDK of this series was called Rear Admiral Gren. They managed to lay it in Gdansk, but after the collapse of the USSR, they cut it into metal.

Cannons and "Katrans"
The new BDK is somewhat superior to the ships of Project 755 not only in terms of carrying capacity, but also in terms of the power of onboard weapons. In addition to the AK-176M and AK-630M-2 "Duet" (10 thousand rounds per minute), it carries two installations of the A-215 "Grad-M" multiple launch rocket system of 122 mm caliber. Each includes a laser rangefinder, a control system, 40 guides and throws rockets at a distance of up to 20 kilometers with a rate of fire of two pieces per second. The massive blow of the "Grad" literally sweeps away the manpower and light armored vehicles of the enemy. Thus, the ship is able, even without the support of other naval forces, to cover the landing with dense rocket and artillery fire. Several launchers of the electronic suppression complex will help him to protect himself from enemy missiles. Although, as a rule, ships of this class are not used alone, but as part of a powerful amphibious group.
For the construction of the Gren, the latest developments in shipbuilding were used, high-strength materials and even technologies for reducing visibility were used. There are practically no restrictions on the types of military equipment transported, as long as its total weight does not exceed the permissible value. The BDK can transport tanks, armored personnel carriers, infantry fighting vehicles, army trucks or towed artillery over distances of up to 3.5 thousand nautical miles. All this economy is located on the so-called tank deck. The equipment can be loaded in different ways: by a portal or deck crane, it can also drive along the aft ramp under its own power. In addition, the BDK can transport standard 20-foot sea containers. The stern superstructure is equipped with a hangar for the Ka-29 airborne transport helicopter or the Ka-52K Katran attack helicopter.

Bridge to the shore
The Grena trademark is the so-called non-contact method of landing troops on an unequipped coast. For this, engineering pontoons are pushed out into the water from the open bow gates, one after the other, which, when coupled, form a bridge. It "docks" with the coastline and serves as a ferry for heavy equipment and marines. This arrangement allows you to maintain a distance between the ship and the shore and reduces the risk of running aground. Light amphibious infantry fighting vehicles, armored personnel carriers and infantry fighting vehicles can be released directly into the sea both from the stern and from the bow: they will reach the coast on their own. Interestingly, immediately before disembarking, tanks and infantry fighting vehicles usually idle, and the landing hold is quickly filled with exhaust gases. To prevent the paratroopers from being poisoned, they open the upper cargo hatch. The landing is possible when the sea is rough up to four points.
The "heart" of the BDK is two 16-cylinder V-shaped diesel engines 10D49 with gas turbine supercharging with a capacity of 5200 horsepower. They accelerate the ship to a maximum speed of 18 knots. In autonomous navigation "Gren" can be up to a month. For a crew of about 100 people and marines, there are enough comfortable conditions for accommodation in cabins and cockpits, there is even a gym.

Ivan Gren "is the lead ship of Project 11711. The Nevsky Design Bureau has been working on it for several years, the project has been repeatedly redesigned to meet the changing requirements of the Ministry of Defense. The Baltic shipyard Yantar was involved in the construction. The second ship of the series, Petr Morgunov, is being completed there. It is planned to transfer it to the fleet in 2018. More such ships will not be built - the command abandoned them in favor of even larger and more capacious ones.
Large landing ships are versatile workhorses, without which no serious military operation on the territory of countries with access to the sea can do. It was on them that in 1986 citizens of the USSR were evacuated from engulfed in fire. civil war Yemen, and in the early 1990s - the personnel of the Soviet naval base Nokra from Ethiopia. During the Georgian-Abkhaz conflict, refugees and Russian tourists were taken out of the combat zone by "paratroopers". In 1999, the BDK of the Black Sea Fleet participated in the transfer of the Russian contingent of peacekeeping forces to Yugoslavia, and in August 2008, they landed troops in the Georgian port of Poti. These ships played the most important role in the operation of the Russian Armed Forces in Syria. In addition to transporting goods, people and equipment, the large landing craft can also be effectively used for laying sea mines.

The large landing ship "Ivan Gren" of project 11711 (according to NATO codification Ivan Gren) will soon become the most modern large landing ship in the Russian fleet. The large landing craft "Ivan Gren" is designed for the landing of troops, 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 preparing for launching. The Russian military abandoned the further construction of ships of this project in favor of creating even larger and more capacious ships of this class.
At the end of December 2017, the general director of the Baltic shipyard Yantar, Eduard Efimov, told reporters that the large landing ship Ivan Gren had entered the final stage of state tests. Shortly before this, the newest Russian ship conducted its first firing and checked the naval artillery in the Baltic Sea. It should be noted that "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 financing and problems at the enterprise itself.
At the same time, a new ship in the fleet is undoubtedly awaiting. Adding it to the fleet will significantly expand the capabilities of the Russian Navy at sea and in remote regions of the planet. Landing ship of the ocean zone "Ivan Gren" 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 helicopter technology. It can take on board up to two Ka-29 transport and combat helicopters, or Ka-27 search and rescue helicopters. If necessary, it will be able to accommodate the Ka-52K Katran attack helicopter.
Large landing ships of project 11711 are a further development of the Soviet large landing craft project 1171 "Tapir". The design of the ships of the new project was carried out by the Nevsky Design Bureau. The project 1171 ship hull was taken as a basis for a reason, it has proven itself well over the decades of service in the Soviet, and then the Russian fleet. At the same time, most of the structures within the framework of the new project have undergone significant changes. Mainly, the superstructures and interiors of the landing ship were redesigned. During the construction of the large landing complex "Ivan Gren" were used the most modern technologies, in particular, aimed at reducing visibility through the use of modern technical solutions and materials. In addition, increased attention was paid to the accommodation conditions for the ship's crew and paratroopers. A gym, a canteen, as well as more comfortable cockpits and cabins appeared on board the large landing craft.
The loading of military equipment onto the ship can be carried out either independently by 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. There are also two boat cranes on board for loading motor boats, lifeboats and equipment. Among other things, the cargo hatch of the ship can be used for ventilation, removing exhaust gases from operating equipment from the under-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 low air temperatures. Exhaust gases from idling vehicles fill the landing hold quite quickly, so ventilation through the upper cargo hatch is simply necessary, thanks to which the paratroopers will not be poisoned by exhaust gases.
The main feature or "feature" of the Project 11711 ships is the so-called non-contact method of landing troops on an unequipped coast. For this, engineering pontoons can be pushed out into the water from the open nasal flaps, which, when coupled, form a bridge to the shore. This pontoon bridge joins 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 large landing craft and the coast, seriously reducing the risk of running aground.
The capabilities of the Ivan Gren large landing craft allow it to transport by sea tanks, infantry fighting vehicles, armored personnel carriers, army trucks or towed artillery at a distance of up to 3.5 thousand nautical miles (at a speed of 16 knots). Military equipment is transported on the so-called tank deck. The equipment can be loaded on board in different ways: by deck or portal crane, and it can also be loaded on board the ship on its own through the aft ramp. In addition to military equipment, the BDK can carry various cargoes, including standard 20-foot sea containers. Among other things, standard 20-foot sea containers can accommodate the Club-K missile system, which is a modification of the Caliber missile system. At the same time, it is unlikely that any missile systems will appear on board the Ivan Gren large landing craft, since countering enemy ships is not part of its direct tasks.
Light amphibious armored personnel carriers, infantry fighting vehicles and BMDs can be released into the sea directly from the stern and bow of the ship, they are able to reach the coast on their own. The landing is possible when the sea is rough up to 4 points. Due to the range of the "Ivan Gren" has the ability to remotely drop, he 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 Ivan Gren large landing craft is two 16-cylinder V-shaped diesel engines 10D49 with gas turbine supercharging with a capacity of 5200 hp. The power plant's capabilities allow the ship to accelerate to a maximum speed of 18 knots. The ship's crew consists of 100 people. The most modern BDKs in the Russian fleet before the appearance of the Project 11711 ships were the Polish-built Project 755 BDK. "Ivan Gren" surpasses them in displacement - 5000 tons versus 4080 tons for ships of Project 755, 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 amphibious capabilities are also higher.
As part of the work on the project and the construction of the ship, its armament has undergone changes. According to the initial project, one 76-mm artillery mount AK-176M, two anti-aircraft artillery complexes "Broadsword" and two launchers of the multiple launch rocket system A-215 "Grad-M" were to appear on board the BDK. However, due to the fact that the concept of using the BDK project 11711 has undergone changes, as well as to save money and time for building the ship, in 2010 it was decided to change the composition of the armament, which today is purely defensive in nature.
The armament of the large landing craft "Ivan Gren" is represented by one two-automatic shipborne 30-mm automatic artillery mount AK-630M-2, two AK-630 mounts with a 5P-10-03 "Laska" radar fire control system, two 14.5-mm mounts MPTU " Sting ", as well as the complex of fired passive jamming 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 antimissile defense of naval ships in the near zone. First of all, it is designed to destroy anti-ship missiles and other types of guided weapons. Also, the installation can solve the problem of engaging enemy aircraft, helicopters and UAVs, small-sized surface and coastal targets. The effective firing range is 4000 meters.
Installations AK-630M-2 and AK-630 are built according to the scheme of multi-barreled weapons (6 barrels each) with a rotating barrel block (the so-called Gatling scheme). Automation of Russian installations of this type works at the expense of the energy of powder gases and, unlike foreign analogues (Phalanx CIWS and Goalkeeper), does not require external energy sources to rotate the barrel block. 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 the turret, which received a lower radar signature.
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 engage lightly armored targets at ranges up to 2000 meters and 1500 meters in height. For firing at air, surface and coastal targets, cartridges are used with the B-32 armor-piercing incendiary bullet, the BZT armor-piercing tracer bullet, and the MDZ instant incendiary bullet.
On the Internet and various media, one could find allegations that the new Russian large landing craft of project 11711 are supposedly a kind of replacement for those built in France, but never transferred Russian Federation - universal amphibious assault ships of the Mistral type, but this is absolutely wrong. Firstly, the construction of the Ivan Gren large landing craft began long before the decision of the Ministry of Defense to purchase Mistrals in France, and secondly, the ships are difficult to compare even in their technical capabilities, mainly in size. It is incorrect to compare them due to 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).
AK-630M-2 "Duet" - Russian shipborne two-automatic 30-mm automatic artillery mount
It is more correct to compare the new Russian large landing craft of project 11711 with the Chinese ships Type 072-III (class Yuting-II), which are large tank landing ships, which are the main amphibious means in the naval forces PRC. With similar characteristics and dimensions, russian project in a favorable direction is distinguished by the presence of a full-fledged helicopter hangar on board.
Despite the fact that Russian naval sailors are not interested in the further acquisition of the Project 11711 BDK (information about this appeared in 2015), abandoning them in favor of larger ships of a new generation, it is too early to put an end to the further prospects of the Project 11711 BDK. Currently, the ship already has an export passport, so it can be promoted by Russia for export. This was reported by the TV channel "Zvezda" with reference to Sergei Vlasov, who is director general Nevsky Design Bureau. Judging by the official catalog of the United Shipbuilding Corporation (USC), we are talking about the 11711E project, which received a displacement increased to 6600 tons.
The ships of the Priboy project can be attributed to the larger landing ships that may appear in the Russian fleet in the future. Within the framework of the Army-2015 forum, a mock-up of universal landing ships of the Priboy project was presented for the first time with a displacement of more than 14 thousand tons and a capacity of up to 500 paratroopers, 20-30 tanks or 60 units of various military equipment... Among other things, these ships will be able to take on board up to 8 Ka-27 or Ka-52K helicopters.

The large landing ship (BDK) of project 11711 "Ivan Gren" was included in the 121st brigade of landing ships of the Kola flotilla of the Northern Fleet. The St. Andrew's flag was raised above the ship at the Yantar Baltic shipyard in Kaliningrad. The long saga, which more than one sailor, sighing, called "opupea", is finally over.
Large displacement ship
Project 11711 was born in the Nevsky Design Bureau back in the Soviet years. Brought into the nineties. The contract for the construction at the Yantar plant was signed in 2004. It was supposed to go into operation in 2008. But…

However, the problem arose where it was not expected. As the sailors say with a grin, it was created by the leadership of the fleet itself. Today it is no longer clear what was primary - a lack of funding, because of which the command was looking over options for what could be built "cheaply and angrily", or uncertainty in understanding what the naval authorities want, why the money was spent on more clearly outlined "Wishlist". But, in any case, even after 6 years of construction, the drawings were shaken up and changed, trying to achieve something incomprehensible, but above all - to reduce the cost. The terms of reference changed three times!
Still - after all the shake-ups, "Ivan Gren" still cost a tidy sum of 5 billion rubles! And there were no tasks for this amount. If to coarse, then - who and where to drop?
The answer to this question appeared only in 2015, when it was necessary to urgently organize a "Syrian express" to deliver a variety of goods to Syria for the fighting Aerospace Forces and two bases in this country. And there were not enough ships for this - they almost begged for barges from the Turks.
In this sense, "Ivan Gren" was just very good for the court. It can carry up to 300 paratroopers, up to 13 tanks or up to 36 armored vehicles of the main types, as well as towed artillery. The cruising range is up to 3.5 thousand nautical miles, the speed is 16 knots. For disembarkation on the unequipped coast, there are engineering pontoons, which, interlocking, form a bridge from the ship to the coast. The landing is possible with waves up to 4 points.
Displacement - 5 thousand tons, length - 120 m, draft - 3.6 m. Engine power - 5200 hp. The crew is 100 people.
Armament - purely defensive: 30-mm automatic artillery mount AK-630M-2 "Duet" with a rate of fire up to 10,000 rounds per minute, two AK-630 mounts with a radar control system. These are mainly anti-missile weapons, as well as the KT-308-04 "Prosvet-M" complex - fired passive jamming. The same purpose is served by two 14.5-mm naval machine gun mounts MPTU "Sting" - although, of course, they can shoot at ground targets at a distance of up to 2000 meters. There are two helicopters (or one attack type Ka-52 can be supplied).

The long-awaited and ...
According to evil tongues, "Ivan Gren" was built so much that it was outdated even before the transfer to the fleet. It is with this that the skeptics explain the fact that the large series (18 ships) was reduced to only two. And that is only because it is impossible to cut the already almost completed sister-thorn "Pyotr Morgunov" on pins and needles! Although when it will be handed over, no one knows for sure.
But the main thing is that it turned out that the "Gren" has serious problems with stability and reversing. And experts say that the very feverish alterations of the project are to blame for this.
And all the same pessimists see behind this a much more alarming symptom - Russian shipbuilders have forgotten how to make large ships. Well, in any case, the military. And where does such a skill come from if they have not been built for more than 20 years? And even then - after all, Project 11711 is based on Project 1171. This is the old Soviet large landing craft "Tapir", on the hull of which everything that is now called "Ivan Gren" is built.
In general, an unconditional holiday - and the commissioning of a new ship is always a holiday - is spiced today for many people involved in the fleet with a fair amount of bitterness. How much we have lost during the years of liberal timelessness! How much have the economic experimenters taken away from us! How much we have lost - including an entire generation of shipbuilders!
And today, moreover, it turns out that the experiments are not over ...
According to TASS, on the day of June, on the 25th of 2019, a new large landing ship of project 11711, Ivan Gren, made its first trip to sea. The vessel left the Baltiysk naval base for the first sea trials in its history. According to information sources, the ship during the tests, which should last several days, must travel several hundred miles to fine-tune the working units of the propulsion and steering installations.
The large landing ship should become the first full-fledged combat ship in the Russian Navy, capable of carrying out the entire spectrum of landing operations at sea. The complicated foreign policy situation in the world today requires the Russian naval command to rush into commissioning such ships. France's refusal to transfer two Mistral-class amphibious assault ships to the Russian fleet prompted the acceleration of the construction of the Project 11711 large landing craft. Laid down back in 2004, the ship stood for a long time on the stocks of the Kaliningrad shipyard Yantar without movement. Affected by the insufficient financing of the project and the uncertainty that reigned in the highest military-political circles of the country about the feasibility of building ships of this class. Today it seems that the situation has moved off the ground and the domestic fleet will finally begin to receive the long-awaited ships.
The story of the birth of project 11711 - Ivan Gren
The increasing role of amphibious assault operations in the modern strategy of strengthening the military presence served as a signal to start developing design documentation for new warships. Marine Corps presents in structure navy one of the most efficient tools capable of solving tactical tasks quickly and efficiently. The combat equipment and the high power-to-weight ratio of the Marine Corps units required an increase in the transport capabilities of the fleet. The available amphibious ships of the old Soviet construction did not fully meet the assigned tasks. The Navy needed a ship that would not only become a means of delivering troops, but would also perform the functions of a headquarters unit - a mobile military-technical base.
The terms of reference for the development of the project were received in 1998 by the Nevskoe Design Bureau located in St. Petersburg. This enterprise already had experience in designing ships of this class and could present the already existing developments in this regard. Initially, the technical assignment was based on the idea of \u200b\u200bcreating a landing ship with a small displacement, capable of carrying out amphibious transportation in inland waters. The main region of navigation of the new vessel was also supposed. This was supposed to be the water area of \u200b\u200bthe Baltic and Black Seas. In the future, the concept of creating a ship with a small displacement was revised. The high naval command decided to focus on the option of building a large amphibious assault ship with an increased displacement, capable of solving a wide range of operational and tactical tasks anywhere in the world ocean.
It should be noted that during the development of the project, changes were made to the main idea three times. The result of almost 6 years of design development and research was the emergence of a vessel of a completely different class - BDK project 11711. The design displacement was increased to 5000 tons. The ship's combat capabilities have increased significantly. It was assumed that the ship should be free to accommodate a reinforced Marine Corps unit with the entire set of infantry and heavy weapons. For the landing of amphibious groups, the ship must be equipped with two helicopters and other delivery vehicles, including sea pontoons and lifting and unloading mechanisms.
The Kaliningrad Shipyard Yantar was chosen as the construction site, the enterprise which today is one of the main shipyards engaged in the construction of ocean-going combat ships.
Construction progress of the new generation large landing complex Ivan Gren
The lead ship of Project 11711 was laid down at the end of 2004, on December 24. Initially, the project provided for the subsequent construction of five serial ships of this class. The ship is named after the famous Soviet vice admiral and theoretical scientist in the field of naval artillery I.I. Grena. Despite the fact that the project already carried a number of significant changes, during the construction of the ship, designers and shipbuilders made up to two dozen changes. The new BDK received the code "Ivan Gren" in the NATO classification.
The subsequent course of construction of the ship was accompanied by a series of uncoordinated actions between the contractor and the customer, as well as in terms of financing. Construction dragged on for many years. The state defense order was repeatedly redrawn, postponing the date of launching the ship. With the readiness of the main ship systems and the hull by 70%, the large landing craft "Ivan Gren" was launched only in the spring of 2012. It should be noted that even in the course of solving the technical and economic problems with the construction of the lead ship, in 2010, design work the second ship of the same type. The construction of the first serial ship was planned to begin no earlier than 2014, only when the lead ship goes through all the stages of revision and current modernization.
The decision on serial production and the number of ships of this class will be made based on the results of tests of the lead ship.
Real progress of construction battleship caused a lot of rumors, both on the part of the naval leadership and among military experts. The large landing ship "Ivan Gren" experienced the financial crisis that affected the shipbuilding industry and the unwillingness of the domestic defense industry to supply the necessary equipment and weapons.
According to the management of the Kaliningrad Shipyard "Yantar", funding has begun sufficiently only at the beginning of 2014. The result of numerous inspections of the condition of the shipyard and compliance with construction plans was the renegotiation of the old contract for the construction of the ship. The new document already carried information about a different, higher cost of construction, more specific and acceptable deadlines for the delivery of the object were established. According to a number of special sources, the contract value of the landing ship "Ivan Gren" in 2012 amounted to more than 5 billion rubles.
After launching the ship, clear contours and directions for further work were outlined. Together with the hull works, the switchboard is being installed, diesel generators are being installed in their places.
Adjacent enterprises have lagged behind the pace of ship construction. The main propulsion system DRRA3700 was supposed to be supplied by the St. Petersburg plant "Zvezda", however, according to the latest data, the finished engines could go to the shipyard for subsequent installation on the ship only in 2012. The situation, which got off the ground, gave ample ground for rumors that the lead ship would be the last and the subsequent serial production of the same type of ships is not planned.
The head large landing craft of project 11711 "Ivan Gren" in May 2012 was brought to the launching dock of the Kaliningrad shipyard. It was expected that in late 2013 or early 2014 the ship will be handed over to the fleet.
The main design features of the large landing craft project 11711
The new ship has a hull length of 120 meters and a width of 16.6 meters. At the same time, the draft of the ship is only 3.6 m. The total displacement of the ship varies within 5 thousand tons. The Large Landing Ship has a seaworthy hull shape and rapid hull contours, allowing for long sea voyages and sailing in stormy weather.
The power of the reverse diesel engine is 4000 hp, providing the ship with a speed of 18 knots. The cruising range of the Ivan Gren large landing craft is 3,500 miles, which is quite enough for carrying out operational activities in the closed waters of the Baltic and Black Seas. The vessel had a crew of 100 sailors and officers and could autonomously stay at sea for up to 30 days. According to all the declared tactical and technical characteristics, the ship met modern requirements, however, during the construction process, the issue of effective replacement of imported components, electronic equipment and individual components of the power plant arose.
There were no special problems regarding the equipment of the weapons system. In the future, only artillery systems were supposed to be installed on the ship. The main caliber was represented by automatic installations AK-176 of 76 mm caliber. The air defense of the Large Landing Ship was provided by two AK-630M anti-aircraft artillery mounts with 30 mm guns.
Fire support to the airborne units could be provided by the naval version of the Grad-M multiple launch rocket systems, the A-215 rocket launcher. Aerial reconnaissance in the area of \u200b\u200boperation of the vessel was provided by two Ka-26 helicopters.
Landing function and cargo capacity of the vessel
We should also dwell on the technical features of the landing craft of this project. Units intended for subsequent transportation and landing are placed on a closed tank deck. The landing ship of project 11711 could accommodate up to 300 personnel of the Marine Corps unit in its bowels. The spacious and capacious hold of the ship was able to accommodate 30 tanks or the same number of other armored vehicles. The internal useful volume of the vessel's cargo holds was designed to load twenty 20-pound cargo containers.
The new ship had two methods of loading and unloading amphibious cargo. Unlike the unloading of troops through an open ramp, traditionally used in the Soviet and Russian navies, the Large Landing Ship could offer two options for loading and unloading. The vessel could carry out loading and unloading of equipment through the ramp located in the bow of the hull or using port and its own lifting and loading mechanisms. For this purpose, there was a hinged hatch in the upper deck of the warship. The ship had the technical ability to make open access from above to the tank deck, providing good ventilation of the ship's holds when the engines of armored vehicles were running. The lifting capacity of our own crane is 16 tons. On the sides of the vessel, there are also two boat lifting devices that allow you to quickly lower or raise boats and landing boats on board.
The landing ship "Ivan Gren" was equipped with two large and one small motor boats.
New story with BDK project 11711
Having received quite acceptable results and the pace of construction of the lead ship, the Ministry of Defense of the Russian Federation decided to start construction of the second landing ship of Project 11711. The contract within the framework of the new State Defense Order was signed in the fall of 2014. The new Large Landing Ship was named "Petr Morgunov" at the stage of the project and was significantly different from the prototype. The base of the new large landing craft is planned to be Black Sea Fleet... It is no coincidence that the ship was named in honor of the hero of the defense of Sevastopol in 1941-42, General Pyotr Morgunov.
It was decided to carry out the construction there, at the shipyards of the Baltic Shipyard Yantar in Kaliningrad. In accordance with the state defense order, the new vessel was planned to be launched in 2019 and transferred to the fleet within the next two years. Later, the estimated dates for the commissioning of the ship were shifted again. The official keel of the vessel took place in June 2019. The ship "Pyotr Morgunov", which received the serial number 01302, must enter the service of the fleet no earlier than 2019.
Today, a completed ship hull is on the stocks of the Yantar plant, and the main components, assemblies and communication systems are being loaded onto it. Two years after the laying, the vessel is preparing for launching, where further work will take place.
The new ship is characterized by significant changes in comparison with the basic design. Despite the fact that the designers tried to leave the standard design unchanged, on the second ship they tried to take into account the test results of the lead ship.
Today, designers and shipbuilders have to comprehensively solve the problems of import substitution. It is required to reduce to a minimum the presence of foreign-made components and parts in the ship's structure. Project 11711 is being revised again taking into account new circumstances and requirements. During the construction of the lead ship, shipbuilders relied mainly on domestic components and components, while on the second ship they relied on the use of foreign technologies. Today this issue is being resolved at a rapid pace, despite the fact that certain difficulties constantly arise. At the moment, there are various options for technical solutions by domestic enterprises. The build quality will already be revealed during the commissioning and acceptance tests.
BDK Ivan Gren today
Currently, the situation with the fate of the Project 11711 Large Landing Ships is more or less determined. Acceptance tests of the head large landing craft "Ivan Gren" are in full swing. The ship checks the operation of all systems on the move in various modes. The operation of the steering and navigation equipment is being checked. Sea trials are scheduled to be completed in September 2019, after which routine maintenance will be carried out on the ship. The start of state tests is scheduled for the fall of 2019, after which the ship is likely to enter service with the Baltic Fleet.
Comparison with foreign vessels of this class in this case is incorrect. Despite the huge number of changes in the project, the large landing craft "Ivan Gren" and its younger brother are rather an intermediate class of ships, a cross between medium landing craft and large amphibious assault ships of the "ship-dock" type.
The state of affairs with the construction of the second ship of the large landing craft "Petr Morgunov" allows us to say that the ship will be built and launched on time. Difficulties arising from the import substitution program called into question further destiny project 11711. According to some media reports, the Supreme naval leadership is inclined to think about stopping the construction of ships of this class in the future. More than 13 years have passed since the laying and before sea trials of the lead ship. During this time, the state's naval strategy has changed somewhat, and today the fleet requires more powerful and versatile landing craft capable of autonomously solving operational and tactical tasks.
