    That means they did not just chuck the hull outside to get rid of it! Laughing

    If they can work out how to make it super stealthy and they learn how to make it faster and more efficiently then this might be how they make their new Destroyers and Cruisers in the future...

    Making it in one piece like this eliminates seems and gaps that can increase RCS, but they need to put it on a real ship and test it... what if it cracks and falls to bits, what if it is brilliant and much better than any other materials they currently use...

    They wont know till they do full and extensive tests, but it is very interesting...

    Word is the cost of this thing is close to that of a Gorshkov class and that's why they won't build a series of them and mercury will remain a test ship/technical demonstrator. Which isn't necessarily a bad thing.. To learn and innovate you have to.Build stuff and test it,. But I expect it to be like the zumwalt of the Russian navy.

    Yeah, its just fecking unbeliveable that some people suggested that was the case... Some people just have hidden agendas and couldn't care less about truth and reality as they work to spread their BS narratives about "Russian failures"...

    Yes it will be expensive (compared to a typical 203850) - its a friggin R&D project of a fundamentally new type of warship. There will be developmental overheads that will be written up against the cost of the lead unit. Same for every project, ever...

    The real question is what benefits the new vessel will bestow, and what the incremental price for serial units will be. No way to know yet, so we just watch this space and ignore the perennial detractors of all things Russian when they try on their spin-doctor BS.

    Of course it is expensive... the first computer hard drives were hundreds of thousands of dollars each and they only had a few megabytes of space, but it was superior to its alternative... it is still cheaper than flash memory like USB sticks... you can pay about 50 cents a GB for a USB stick so about 16 dollars for a 32GB stick... if hard drives were that expensive then a 2 TB disk would be $1,000 dollars instead of the $100 they normally cost.

    They need to check performance, but also with work and experience with the new materials they can improve production too... wasn't there another boat that used such material and the first one took 30 days to make the superstructure, but the next one took 3 days because they were able to improve the production.

    When you are making stuff some things need to be done in order and others do not... when you first build something you follow the instructions, but after you have made one you can identify what takes time and what does not so instead of making something , letting it cure for a day and then making something else and letting it cure for a day and then joining them together and letting it cure for a day, you could make all the pieces at once and let them all cure for the same day and then assemble them all together and let the assembled parts cure for a second day... surprise... that took three days.

    The first time through you might not have had the capacity to make 100 pieces at one time or assemble those 100 pieces together all at one time, but as you gain experience and expand your factory design and production floor you can make changes to massively speed up the process which will directly impact the costs and time it takes to make a lot of them...

    If you can whack out a complete ship upper structure in 3 days then that is going to compete rather well with doing it all in steel.

    Being able to fix entire areas or hole patch repairs and it might be better than other materials like steel and glass reinforced plastic.

    I think the ships I was thinking about were those mine countermeasures boats that had composite hulls and structures where the first model took a month but they quickly refined the production technique and soon it only took 3 days to fabricate the structure/shell.

    Bigger ships would require bigger facilities, but with larger boats it might be even more efficient and it might make them lighter but just as strong and might end up being cheaper for bigger ships while keeping their RCS low.

    They might find it only makes sense in small boats, which is fine, but it could be that they could make submarines with electric motors and new batteries, with hulls made of this stuff that don't show up on MAD systems and are lighter and can have much better performance in a much smaller boat... who knows till they test it.

    They had to build a whole new mould for this, is a massive part. Even if it cracks its fixable. Its less likely to crack then aluminum. The US Littoral class ships were cracking like crazy.
