The appearance of helicopter carriers will radically change Russia's capabilities at sea
On September 15, 2014, the Vladivostok UDC, built by the French company STX France by order of the Russian Navy at the Chantiers de l'Atlantique shipyard in Saint-Nazaire (France), went to sea for sea trials with a Russian crew on board. And already on December 18 of the same year, due to difficulties with the transfer of the ship, the Russian crew on the training ship "Smolny" departed from Saint-Nazaire for their homeland. So ingloriously for us ended our epic with the "Mistrals".
Let me remind you for those who have forgotten: on June 7, 2011, during the St. Petersburg International Economic Forum, a contract worth € 1 billion 120 million was signed between Rosoboronexport and the French shipbuilding company DCNS. The contract provided for the supply of two Mistral-class UDC (universal amphibious assault ships). The first ship was named "Vladivostok", the second - "Sevastopol", France was supposed to transfer them to the Russian fleet in November 2014 and October 2015, respectively. However, this did not happen for reasons beyond our control. The United States intervened in the matter and blocked the deal, pushing its decision through the gutta-percha Hollande (if anyone has forgotten, this figure was then working as President of France). As a result, France fell under penalties, a loss of business reputation (such an incident happened for the first time in its history!), And we were left without two ships that would be very useful to us in 2015 in Syria (but then we did not even think about Syria yet ).
The UDC were built in a reinforced ice class for operation in northern latitudes, including in difficult ice conditions, and were to be assigned to the Pacific Fleet, but the Americans did their job and we were left without ships. The maximum that we managed was to take the technical documentation from the French for the manufacture of UDC (up to the secret, it included three key Technology, including large-block construction of helicopter carriers and waterproof protection from Admiralte; ski) and money in the amount of € 949,8 million, as well as Russian equipment dismantled from the UDC, which was supposed to be installed there under the contract, after which in 2016 we began to develop technical documentation for the construction of these ships already on their own at their own production facilities.
The result of this work was the laying on July 20, 2020 at the Kerch shipyard "Zaliv" of two UDC project 23900 "Ivan Rogov" (serial number 01901) and "Mitrofan Moskalenko" (serial number 01902) with the planned delivery date to the Customer in 2028-29, respectively ... The lead designer was the Zelenodolsk Design Bureau (ZPKB), which, like the plant, is a subdivision of the Ak Bars Kazan holding. The total cost of the contract concluded between the Contractor and the RF Ministry of Defense was listed in the region of 100 billion rubles. (for both ships), which significantly exceeded the Mistrals' estimates. Such a big difference was explained by the fact that the ships planned for construction significantly surpassed their French counterparts in displacement, width, height, draft, functionality, habitability, transport and landing capabilities, the composition of the landing craft and the quality of the air group.
In the course of the design, not only the displacement of the ship significantly increased (almost doubled - from 21,3 thousand tons to 40 thousand tons), but all its tactical and technical characteristics also grew - the possibility of basing not only deck helicopters on it, but also temporary reception of ground-based combat, multipurpose or transport helicopters, their maintenance, embarkation / disembarkation of various contingents, up to the use of the ship as a headquarters (multifunctional control point) for commanding various groupings of troops (I draw your attention to this point!). At the same time, the standard armament was reduced to defensive - 2 "Pantsir-M" air defense systems. The area of application of the UDC is the entire World Ocean - from warm seas to northern latitudes, accompanied by icebreakers.
UDC building and equipment
According to the project, the hull of the icebreaker class will be made according to the block-modular principle, which provides for the simultaneous construction of its large elements with their subsequent connection, and the sides will not be armored. The ship will have: a navigating bridge; a separate equipped command and staff room; premises for the accommodation of the crew and troops; helicopter hangar; Technical buildings. UDC will be able to transport from 900 to 1000 marines; have on board 10-16 and even up to 20 helicopters, including UAVs for various purposes; the dock chamber can accommodate up to 4 landing craft. Watercraft for patrolling and operational disembarkation will be located on the starboard sponson and in the stern of the ship, if necessary, these places can be partially occupied for the placement of additional armored vehicles. In this case, the dispatch and reception of the landing force will be carried out either through the dock chamber or through the hatches in the sides with the help of floating craft, or from the helicopter deck on aircraft. UDC for this project will be able to serve in the Arctic zone.
Power point
In this case, the propellers are provided with propeller-driven steering columns using a single electric power system. As the main power plant, it is planned to use a combined diesel-gas turbine unit of the CODAG type of Rybinsk production, used for frigates of the Admiral's series of project 22350, consisting of two diesel-gas turbine units DGTA-M55R with a capacity of 32 hp, which includes a diesel engine 700D10 with a power of 49 h.p. (made by Kolomensky Zavod) and an M5200FR gas turbine with a capacity of 90 hp. (made by NPO Saturn), transmitting torque by means of two RO27500 gearboxes (made by PJSC Zvezda) and a local control system of NPO Aurora. Diesel 55D10 and gas turbines M49FR can work together or separately. Thus, two twin-shaft diesel-gas turbine units DGTA-M90R with a total capacity of 55 hp, rotating two shafts, will be able to provide the ship with a speed in the region of 65-400 knots, which is quite enough for warships of this class.

For now, I am forced to put an end to this, I will tell you about the combat use of these ships and the difficulties we encountered in their design in subsequent articles.
To be continued.
