Project 21180 Ilya Muromets

Russia is looking to build up its presence in the oil- and gas-rich Arctic region in accordance with the country's revised military doctrine, signed by President Vladimir Putin in December 2014. The document named the protection of national interests in the Arctic among the main priorities for its army in times of peace, for the first time ever. President Putin said that although Russia did not plan to militarize the Arctic, but would take necessary steps to ensure its defense capabilities in the region.

One possible role of the new icebreaker is hinted at by the history of its predecessors. Another project 97 "bogatyr" icebreaker - "Dobrynya Nikitich" - during service in the Northern Fleet, repeatedly participated in ensuring the transition of nuclear submarines of the Northern Fleet to the Pacific Ocean. Considering the program for the construction of new nuclear submarines of the Yasen and Borey projects at the plant in Severodvinsk, it can be assumed that icebreakers of Project 21180 will be engaged in their escorting to the Pacific Fleet. In any case, the cruising range, autonomy, passenger capacity, and carrying capacity , and the icebreaking ability is quite possible for them. Project 21180 icebreakers are Russian diesel-electric icebreakers of auxiliary class of a new generation. Evpaty Kolovrat, developed by the Vympel design bureau in Nizhny Novgorod, will have a length of 82 meters, a width of 19 meters and a draft of 4.6 meters. The maximum speed that the ship can reach is 14 knots, the total displacement is 4080 tons. The crew of the icebreaker will consist of 28 people.

The icebreaker is designed to guide ships and vessels of the Russian Navy, as well as towing and delivering cargo to remote bases, assisting ships in distress in ice conditions. He will be able to overcome ice one meter thick at a speed of two knots. The range of the vessel to reach 7600 miles.

The Ilya Muromets icebreaker is noted for simplicity. In fact, this is a multifunctional support vessel of high ice class. But since the Arctic will become the main place of service for him, the ability to pave the way for himself and the "ward" ships in ice up to a meter thick came to the fore. In addition, "Ilya Muromets" will be able to supply coastal and island bases and airfields in the Arctic zone; towing of vessels and other floating structures in ice conditions and on clean water; extinguishing fires at emergency facilities; containment of spills and collection of oil products from the sea surface; transportation of containers on the open part of the upper deck, including refrigerated containers with appropriate power supply, as well as other deck and hold cargo.

When this ship was being designed, the characteristics of the icebreaker were not even of today, but of tomorrow, said the commander-in-chief of the Russian Navy, Admiral Viktor Chirkov, on the day the Ilya Muromets was laid down. - It is seaworthiness, maneuverability, versatility and a completely new electric principle of movement. The conceptual principle of shipbuilding, incorporated in the shipbuilding program for the period up to 2015, has been implemented - this is multifunctionality. " And this statement accurately reflects the purpose and capabilities of the new icebreaker.

The Ilya Muromets is a multitask vessel capable of breaking through ice fields to make a passage for other ships, and can tug ships as well as transport a certain amount of cargo, delivering supplies to remote and secluded military installations. The ships length is 85 meters, its beam is 20 meters, draft is 7 meters with deadweight of 6,000 tons and cruise speed is 15 knots. The crew is 32 people. The vessel would have a cruising range of 12,000 nautical miles and an endurance run of two months.

The data on the Ilya Muromets engine looks even more innovative. It will be equipped with four diesel generators with a total capacity of 10 600 kW (each generator has a capacity of 2600 kW). They will power two propeller motors with a capacity of 3500 kW each, installed in separate rudder propellers. It is they who make "Ilya Muromets" a unique vessel: the electric motors outside the hull with propellers on their shafts rotate 360 fegrees, allowing the vessel to move in any direction. Exactly what is needed in ice, when sometimes it is required to give not just a forward or a back, but a "side" course, and Ilya Muromets is quite capable of doing this.

Such engines are called "Azipod", which is made up of the words azimuth (literally - azimuth, polar angle) and pod (in this case - engine nacelle). Such rudder propellers are, for example, on the infamous Mistral helicopter carriers, as well as on the Arctic tankers of the R-70046 project (Mikhail Ulyanov), which were built several years ago at the Admiralty shipyards. But such engines are installed on icebreakers for the first time in Russia. And on "Ilya Muromets" will be installed propeller-driven propellers of domestic production: especially for the ships of this project, they were designed and produced by the Central Research Institute of Marine Electrical Engineering and Technology (Central Research Institute of Marine Electrical Engineering and Technology) in St. Petersburg.

On board the new icebreaker there is a cargo crane (length - 21 m, lifting capacity - 21 t) and a manipulator crane (length - 21 m, lifting capacity - 2 t), a multipurpose work boat with an inflatable board BL-820, two water-foam monitors and a fire pump. And, in addition, 400 meters of booms and a launch boat for them: this is part of the equipment for collecting spilled oil. To this must be added the carrying capacity equal to 500 tons, 380 square meters of cargo deck on the icebreaker's quarterboard and 500 cubic meters of cargo hold. Plus a helipad on the tank,

Another characteristic feature of the icebreakers of Project 21180 can perform not only auxiliary, but also quite combat functions. Unlike conventional icebreaker superstructures, which have a vertical front wall, military icebreaker patrol superstructures have a very recognizable sloping front wall, reminiscent of the superstructures of modern frigates and destroyers. Ilya Muromets has exactly the same. And the free space between the helipad and the superstructure is quite enough so that, if necessary, an artillery mount of the AK-230, AK-630 or AK-306 type can be installed there (the latter is most likely).

On December 12, 2014, the main contractor of the order - Admiralty Shipyards - and KB Vympel, as the developer of the icebreaker 21180 project, defended the technical design materials from the general customer - the military. By this time, at the preparatory site of the shipyards, metal was being cut for a month for the construction of a new vessel. On April 23, 2015, the laying ceremony of the Ilya Muromets icebreaker took place. The lead ship of the new series should be commissioned at the end of 2017.

The Russian Navy will kick-off the construction of its first diesel-electric icebreaker over a few decades Navy Commander Adm. Viktor Chirkov said. The group of the Russian Navy in the Arctic will receive a universal ship capable to be simultaneously an ice-breaker, an ocean tug and a patrol ship, Navy Commander Admiral Viktor Chirkov told reporters on 17 April 2015. "A decision was made to design and build - in the middle-term prospect - a universal ship of a new generation, with possibilities of a fleet tug, icebreaker and patrol ship at the same time," Chirkov said. "This universality will allow the ship to fulfil a broad range of tasks in the Arctic area. We are going to outline its design this year."

The ship will be capable of breaking ice that is 80 cm (or more than 30 inches) thick, according to Chirkov. "On April 23, the Admiralteiskie Verfi [Admiralty Shipyards] company in St. Petersburg will start constructing the Ilya Muromets diesel-electric icebreaker due to become the first one for the [Russian] Navy for a few decades," he said.

The Admiralty Shipyards in St. Petersburg floated out the new generation diesel-electric icebreaker Ilya Muromets (Project 21180), commissioned by Russias Defense Ministry. Work on the ship, which is built to explore northern latitudes, started in April 2015 and was expected to finish in late 2017. It is the first icebreaker completed in Russia in 40-45 years for the Navy.

In November 2017, the transfer of the head icebreaker of the project 21180 Ilya Muromets, the first icebreaker in 40 years, built exclusively for the needs of the Russian Navy, took place at another St. Petersburg enterprise Admiralty Shipyards. According to the head of the press service of the Northern Fleet, Captain 1st Rank Vadim Serga, on January 2, the ship completed the inter-fleet passage from St. Petersburg to Severomorsk, however, the official date of joining the Northern Fleet is November 30, 2017, when the naval flag was solemnly raised on the icebreaker.
