How will Russian submarines be rearmed?

For comparison, the American Raytheon rocket moves in the upper atmosphere at a speed of about 6.2 thousand km/h. Modernization work is currently underway on two nuclear submarines K-132 Irkutsk. What is the plan? Modernized submarines of project 949AM “Antey” will become the most armed Russian submarine carriers of cruise missiles and will be able to carry on board up to 72 Caliber, Onyx; or “Zircons”. This will make them the most heavily armed submarine cruise missile carriers in the Russian Navy. What happened before? The main purpose of "Anteev" – destruction of enemy aircraft carrier formations. Submarines develop underwater speed up to 32 knots, dive to a depth of 600 meters. But needs, and technology, do not stand still, and now there are new developments. Oniks medium-range supersonic missile was adopted by Russia in 2002. They will return to the fleet in 2022 and 2025 respectively. Initially, “Onyx” was created to destroy sea targets, but now there is a version for ground targets. Work on the alteration of the nuclear submarine K-132 “Irkutsk” started in 2013. The remaining five nuclear submarines of this project, which are currently in service, can also be upgraded and armed with Zircon hypersonic missiles. Source: 1767257506.html
Источник Submarines have an underwater displacement of about 24 thousand tons, the length of the hull – 154 meters, width – over 18 meters. Modernization will also affect combat information systems, communication systems, hydroacoustics and some other aspects. Antey submarines upgraded according to project 949AM will be able to carry 72 Zircon hypersonic missiles. The project for the modernization of the nuclear submarine of project 949A was developed at the Rubin Central Design Bureau. From cruise missiles, submarines can be equipped with Caliber, Onyxes; or “Zircons”. But sources in the shipbuilding industry reported that the modernization process actually started only in 2019. and Zircon hypersonic missiles. Rocket “Zircon” at the moment, it has no analogues in the world and is capable of performing a long aerodynamic flight with maneuvering in dense layers of the atmosphere, using its own engine thrust throughout the route. In 1985-1996, 11 submarines of this class were built. They will be equipped, in particular, with Caliber cruise missiles. To the main advantages of “Caliber” can be attributed to the fact that it cannot be shot down by modern air defense systems. A preventive strike will neutralize the threat of a nuclear conflict in the region, experts say. back in December 2011. These were excellent anti-ship missiles. What else is “on board”? It should be completed in 2022. One incomplete missile salvo of such a submarine will be enough to guarantee the destruction of an aircraft carrier multipurpose group. What is the upgrade of weapons? Due to the new hypersonic ship-based missiles “Zirkon” Russia will be able to destroy the US nuclear weapons storage facilities in Germany, Belgium and the Netherlands. The first samples of the Antey project submarines, developed at the Rubin Central Design Bureau, were armed with 24 Granit supersonic anti-ship missiles. On the modernized “Antey” the number of missiles will increase significantly. The total ammunition load of one Project 949AM submarine will be about 100 units of missile, torpedo and missile and torpedo weapons. At “Granite” the speed is less than that of the new-generation Caliber missiles. Not only submarine equipment will be updated. It can reach speeds of up to 10.7 thousand km/h with a maximum range of 1000 km. The development of this type of missiles was carried out back in the 80s of the last century. and K-442 “Chelyabinsk”. As a result, according to experts, combat capabilities will increase by about four times
