    Any submarine expert here would like to comment how much accurate is his information regarding the sound generated by screw blades and pump jets?

    This guy knows nothing exacting about the acoustic performance of either Yasen screws or Borei pump-jets, even if he is an ex-Navy sonar man.  Its just general theory without real numbers.  You could just as easily apply it to detection of Ohio SSBNs and Seawolf/Virginias.  I write it off as typical Yankee bloviating.

    no shit is just a general theory...

    submarine information of that nature is highly classified.

    But as you said he is ex-navy sonar so his ideas are educated.

    Tell me have you ever worked on a submarine? no? oh you just read shit on the web and think you know better riiiiiiiiiiiiiiight.

    ^ He isn't always needling Russia. For an American big baller sub vet, he could be far worse. He says that Russian subs have more roomy crew quarters than US subs. Also that Russian subs have auto loaders and piped foam fire retardant that US subs don't have. He gives Russia credit when he sees something he likes

    Are you off yer meds, or are you deliberately being a clown? Nothing you've puked out in any way undermines what I wrote.

    I'll wait for your answer in case you're unsure.

    Been watching the guy for a year and gotta give him credit, he admits the Russians where ahead in Sub tech in many areas even in the 60s, something you really don't hear from people in the west

    True, but sometimes things are obvious and can't be hidden or fudged.

    Occasionally throwing Russia a bone does not mean right or impartial... many in the west are still stuck on it is our way or the high way... so if we tried it and failed then it is not possible so don't bother.

    Russian shipbuilders to lay down two advanced nuclear-powered subs in May

    The submarines are scheduled to be delivered to the Russian Navy in 2026 and 2027

    MOSCOW, March 5. /TASS/. The Sevmash Shipyard in Russia’s northwest will lay down the improved Project 955A (Borei-A) strategic nuclear-powered missile-carrying submarines Dmitry Donskoi and Knyaz Potyomkin in May this year, a source in the domestic defense industry told TASS on Friday.

    "The strategic subs, the new Dmitry Donskoi and the Knyaz Potyomkin will be laid down at the Sevmash by Victory Day on May 9, 2021," the source specified.

    TASS has no official confirmation of this information yet.

    As the source said, the contract on the subs’ construction was signed in 2020. The submarines are scheduled to be delivered to the Russian Navy in 2026 and 2027. Each submarine will carry 16 Bulava intercontinental ballistic missiles (ICBMs).

    The Project 941 Akula-class nuclear-powered submarine Dmitry Donskoi that has for long been called the world’s largest submarine is still operational in the Russian Navy. This sub was used to test-fire Bulava ICBMs.

    The Russian Navy currently operates four Project 955/Project 955A strategic missile-carrying submarines. The Project 955A submarine Knyaz Oleg is due to be delivered to the Navy this year. Three more submarines of this Project are being built at the Sevmash Shipyard (part of Russia’s United Shipbuilding Corporation).
