    The U.S Navy had stated that US naval reactor tech is a generation ahead, relying on 90% HEU to achieve reactor fuel life of > 30 years while Russia's current level of tech uses 40% enriched uranium that requires the boat to be cut open every 10 years to refuel. Is that true?

    Of course an Indian would believe that nonsense.  I got a bridge to sell you.

    America says a lot of shit regarding their technology.  You have to refuel every 5+ years for nuclear reactors.  And no, you dont have to cut anything open.

    LMAO, I can assure you, the latest reactors developed for the latest classes of American boats, as well as Yasen-M and Borei-A don't need to be refueled every 5-7 years, and you actually very much do have to cut open a submarine hull to refuel the reactor, as was done on older American and Soviet submarines, the only exception is the French, who build in a specific hatch into the hull, but this is a function of them unifying their reactor designs for both surface and submarine fleets which makes such a solution appropriate.

    Older subs maybe.  I doubt you need to do that on a Borei or Yasen. If it is still the case, seems rather odd they would continue the trend.  Maybe refueling isn't the 5 years anymore but hence I added the + in there.

    IIRC the OK-650KPM of the 885M doesn't require refuelling over the boats design lifetime,ie 25-30 years.

    I think it's pretty much standard these days.

    For the Soviet subs of the 80s, refuelling at the mid-life repairs was a standard procedure.

    SSNs like Akulas will have to escort SSBNs. Maybe SSNs will have to be refueled faster than a SSBN.

    The nuclear fission reactors on board the Russian submarines are probably more powerful compared to their U.S analogues.

    Here is an article on RT back in 2018 about the "perpetual" reactor being developed by Rosatom.

    https://www.rt.com/news/435319-russia-perpetual-reactor-submarines/

    "A Rosatom subsidiary said it has developed and successfully tested a “perpetual reactor” capable of powering Russia’s newest nuclear submarines during their entire lifetime – without having to be refueled."

    "Now, with the new invention coming into use, Russian submarines will no longer need to undergo refueling and a reactor overhaul. Admiral Vladimir Popov, previously a Northern Fleet commander, suggested the “perpetual reactor” will see a rapid increase in the Navy’s capabilities, according to RIA Novosti."

    Submarine captain: nuclear submarine with "Zircon" can destroy the Pentagon building, 04/10/2021.

    A submarine with a Zircon missile on board can strike at any target from a distance of 1,000 km without the risk of being noticed, the submariner, captain 1st rank Igor Kurdin, told the VZGLYAD newspaper. The new rocket was successfully tested in the Barents Sea.

    “The range of the Zircon is from 500 to 1000 kilometers. From such a distance, no one will spot our submarine, unless they have been tracking it for a long time and purposefully, "said the chairman of the St. Petersburg Navy Submariners' Club, Captain 1st Rank Igor Kurdin.

    The interlocutor recalled that the task of the American anti-submarine forces is to detect our nuclear submarine before it launches missile launches. “The hypersonic speed suggests that once the Zircon is launched it is virtually impossible to destroy,” he added.

    In this regard, the expert pointed out that Russian nuclear submarines can destroy any major administrative and political center in the United States with Zircon, be it a military base or the central building of the Pentagon.

    On Monday, the press service of the Ministry of Defense reported that the Russian Navy had first tested the Zircon hypersonic missile from the Project 885 Ash nuclear submarine Severodvinsk. The shooting was carried out at a conditional sea target in the water area of ​​the Barents Sea. The flight of the rocket corresponded to the specified parameters, the test firing was recognized as successful.

    “The crew of the nuclear submarine missile cruiser Severodvinsk successfully completed the second test launch of the Zircon hypersonic cruise missile. The second test firing of the Zircon hypersonic cruise missile was carried out by the crew of the Severodvinsk nuclear submarine missile cruiser for the first time from a submerged position, from a depth of 40 meters, in the White Sea at a conditional sea target in the Barents Sea, " RIA Novosti reported.

    Earlier, the Ministry of Defense announced its intention to complete the state tests of Zircon in 2021. It is expected that the Zircons will be armed with frigates of project 22350, the newest multipurpose submarines of project 885M Yasen-M, as well as the missile cruiser Admiral Nakhimov, which is being upgraded, and the submarine Irkutsk, which will be brought to the level of 949AM during modernization.

    The only correction to be made to the article is that the range has been reported as 1500 km against land targets... Wink

    Confirmation that the 949AM will be able to carry Zircons Very Happy

    It was suspected, but nice to have some (semi) official confirmation. thumbsup
