US Navy begins development of new SSN (X) multipurpose nuclear submarine

26

The US Navy intends to soon get into service with a new multipurpose nuclear submarine, which in the future will replace the Virginia class submarines (SSN), which are currently in service.


According to Naval News, citing a report from the Congressional Research Service, the US Navy has already received funds to develop a new multipurpose nuclear submarine, designated SSN (X). So far, little is known about the new nuclear submarine, more and more assumptions. According to the publication, three design options for the new submarine are currently being studied.

In the first version, the new nuclear submarine will be created on the basis of Virginia class submarines, in the second - on the basis of the new generation strategic nuclear submarines of the Columbia class, and in the third - a completely new version. It is absolutely certain that the SSN (X) will be wider than the Virginia-class nuclear submarine and will approach strategic submarines in size, and its advantage will be high speed and increased stealth. According to assumptions, the new submarine may receive more modern equipment and the latest weaponincluding laser.


According to the US Navy, the first multipurpose submarine of the new project is planned to be purchased in 2031, simultaneously with another Virginia. In 2032 and 2033 fiscal years, the last four Virginias will be purchased, and from 2034, it is planned to purchase two new nuclear submarines annually, in order to increase the number of multipurpose submarines in the US by 2048. fleet to 66.

The estimated cost of one nuclear submarine of the new project is $ 5,8 billion (in 2021 prices).

    66 multipurpose nuclear submarines, and how many of them will there be in Russia by that time?

      Very little will be! Our supposedly fleet is a pale shadow of the Soviet fleet, and up to the American one, with such shyness, and eternal long-term construction, in a couple of centuries we will not approach the Yankees in numbers and technical equipment of submarines, which means that we will also be very vulnerable to their submarines, as now ...

        Last week there was an article about the submarine "There is no more secrecy: the submarines of the usual kind are doomed", authored by Timonin and Klimov, in which our submarines were predicted a hopeless future and a joke on their shores, so we will not take by number fellow , but skill and love for the enemy love .

        It is even indecent to think so far, already in 2048, given how the United States, Russia and China are intensively investing in AI and other advanced technologies.

          And the coolest thing is that there will be laser weapons on board the alleged submarine .. How is that? In water what ?? They seem to be removing the railgun from the deceased Zumvolt and installing it too ..

      it all depends on whether multipurpose nuclear powered submarines will be taken into account or written off from Soviet times)
      you need to cut a fast and inexpensive torpedo boat in marketable quantities, otherwise by that time the submarine will be covered with golden ash ...

        or write off multipurpose nuclear powered submarines from Soviet times

        some ALREADY write off
        and the rest have been waiting for repairs in sedimentation tanks for 10 years

          Yes, ours just thought differently before. And then - rraz, and there is no aviation. Two - and there are no tanks. Therefore, it is necessary to develop the right attitude, before the cancer whistles on the mountain.

            Everything was much more complicated and less straightforward.

            Even if we generally agree with the phrase
            And we will not see luck at sea
            the right attitude is not developed either before or during the war.

        And then, that we have 40% of strategic SBS are on SLBMs. And like it or not, in the next 30-40 years we will have to solve the problem of ensuring the security of SSBNs.

          This is the ambush that stands. On day M, they won't even have time to fart. At least in the base, at least at the exit from it. The boat made sense (for Russia, at least) as long as it possessed stealth. Now we do not have it, concealment, as the authors claim here. And they have. Well, let's continue to chew the cactus? And Cho, the money has been paid ?!

    They wanted to build 30 Sivulfs, but they built 3 and they cost more modestly. Let's see what happens. For a new submarine, at least, it is also necessary to develop a new ICBM.

      Yes. It's like that. good

      ICBMs for MAPLs? They will not develop a new one.
      There never was an old ICBM. wink

      Their plans are a good reason for revising the principles of designing our boats for us, it's time to understand that our double-hull boats have lost and will lose to single-hull boats.
      1 and a half times, in the mass of structures
      2 in construction cost
      3 in construction time for small and medium boats
      4 there is always a high probability of delaying the construction time for large ships. type of Belgorod
      5 have a serious loss in technical excellence (the number of weapons per ton of displacement),
      6 they all have excess buoyancy, of the order of 40%, which is due to the gap between the strong and light hulls (somewhere on the order of 60 cm), this is done so that the welder can fit and work there., As a result, the diameter of the light hull is 1.2-1.3 meters larger than the diameter of the strong one, and at the same time it has a large negative buoyancy which must be compensated for by an increase in the size-volume of a strong hull ..., and again an increase in the size of the boat.
      6 an unobvious, but very serious drawback of double-hull boats is the incredible complexity of their modernization, you have to cut two hulls to get inside, and now imagine a conditional single-hull submarine from three compartments - sections that are bolted on flanges, in a dry dock such a boat can be very quickly disassemble into sections while adding or changing one of the sections ..
      7 the increased size of our boats in itself reduces stealth
      8 a double-hull boat is easier to detect using the acoustic method
      9 the number of compartments in our boats is excessive, this complicates their operation and then the very possibility of the boat surfacing when one of the compartments is flooded in wartime, why would the enemy capture the crew together with the boat? there must be a pop-up camera to rescue the crew.

        Are there any advantages of double-hull boats? Why did our constructors make them and are doing them now?

      Are there any advantages of double-hull boats? Why did our constructors make them and are doing them now?

      1 A double-hulled boat with a large buoyancy margin can theoretically break the ice and float, while if there is serious damage to the outer hull, air from the interhull space (ballast tanks) may escape into them, water will get into them, the buoyancy will decrease and the loka will sink immediately or a little later
      2 The outer light hull gives some protection against accidental touch damage or light collisions.
      And the warrior pluses are over
