    It will take 7 more years for this? That's longer than a Yasin subarine.

    They are making two together, and at 40K ton they are probably a little bigger and more complex than any Sub.

    They will likely also have to develop landing ships, and perhaps they might need to coordinate its development with new high speed troop carrying helicopters.

    Talk about putting the Mi-14 back into production is interesting, but would rather see them make a new helicopter based on the Mi-38.... the Mi-14 was basically a navalised Mi-8/17, so a navalised Mi-38 would make more sense than putting the Mi-14 back into production in my opinion.

    Equally a new troop transport helicopter would be good... an improved Ka-29 with a rear ramp door as well as side doors for rapid troop deployment and recovery, with a pusher engine to boost flight speeds would be interesting.

    Russia's shipyards have not been modernized post Cold War to be able to build a LHD at such speed.

    Actually most of their shipyards have been upgraded specifically for the purpose of making new ships. Hopefully their production of Corvettes and Frigates will accelerate including the numbers of shipyards making ships because after a couple of years of making corvettes and frigates they are going to have to start laying down destroyers and get them moving forward too.

    A more realistic timeline for launch of the first ship should be 2040 launch when the shipyard's capability is taken into considering and the launch of the second ship should be on schedule for 2050 to 2060 launch.

    You can consider yourself warned.


    I know I can be banned for calling someone a fucking idiot, but can I be banned for thinking someone is a fucking idiot?

    I don't interpret the rules on member abuse the same when that member indulges in flame baiting and trolling.


    It may be a steep learning curve but at some point down the road this shipyard will be in good enough shape to reliably handle construction of really big ships

    That's when they will be given really important stuff to build

    To be fair these ships should already have a design... they just need to construct them, which is no simple task, the number of steps that need to be performed in the correct order is mind blowing, but this is what they do.

    In all fairness Russia is going to have delays with the ships, they alllllllllways have delays and that's a fact you cannot argue.

    History speaks for itself there.

    However, suggesting 20 or 40 years is just flat out retarded.

    Isnt an amphibious assault ship a lot less complex than an SSN or even gorhskov frigate. Like lets think like this: No need for complex stealth coatings, testing VLS cells, testing sonar, testing depth resistance. Much simpler sensor suite since theres only a need for aircraft control and fire control of self defence weapons. The only complex engineering challenges are probably seaworthiness, cargo holds and hangars for helicopters and their supplies.

    Correct but this particular shipyard while larger than most Russian ones has been out of commission for decades rotting away

    That's why these two LHDs will be a tall order for it but Russian Navy has no use for another shipyard that builds small boats hence why they gave them these two LHDs as "graduation assignment"

    There will definitely be delays but in this case it's part of the job

    There is probably 25 to 30K tons of steel to start with... these ships are not just helicopter carriers... they are intended to carry 1,000 naval infantry plus their armoured vehicles and support vehicles and landing craft to take them from the ship to shore as well as more than a dozen helicopters of a range of different types.

    The ship is essentially an enlarged Mistral and will likely have a modern 200 bed hospital included in its design as well as lodgings and food storage and preparation for 1,000 soldiers in addition to the crew and air compliment, and it is by far the biggest one they have ever made... the original Ivan Rogov class was about 15K ton, so these are almost three times bigger.

    In comparison they have plenty of experience making SSNs and SSGNs...

    The graphic used there is the 15 000t Priboy design, or more likely the 24 000t Lavina. Both these had bow doors.
    The bow shape is also very different to the 2 pictures we have shown with Putin
    The 23900, as described, seems not to have bow doors, and will weigh around 40 000t max. It has a blunter, less sharp bow according to the 2 graphics seen.
    One other thing: A length of 220m is not really compatible with 40 000t. If one looks at the other helicopter carriers, or full-decked assault ships, or even carriers, then with a 40 000t full displacement, one would expect a length over 230m at the very least, but more likely around 240-250m.
    So either the hull is a novel design, being very wide, or the length or displacement is wrong.
    I guess time will reveal all
