https://www.portsmouth.co.uk/news/defence/royal-navy-warship-hms-prince-of-wales-could-be-sold-4537764 I don't believe it's gonna be serious, probably just demanding more funds, but... who knows?

I think it would be feasible to install 3 or 4 mk41 vls tactical modules, that is 24-32 cells for ESSM (quadpacked), SM-2 or even VLA (for ASW) . Either forming a square in the center-line of the multimission bay or arranged in a row, letting still a lot of space on both sides. This would play...

Hello, and Merry Christmas. Has anyone found the correct link to download the english version of the Maritime Eng. Journal (106)? Every link directs to the French version. Thank you.

Problems do arise when undermanning the vessels... https://www.navylookout.com/the-f-35-accident-report-a-reality-check-for-uk-carrier-strike/

It would be a nice idea to early join NL & UK in this project. https://www.navylookout.com/multi-role-support-ships-the-future-of-royal-navy-amphibious-capability/ With about 12 ships to be built, it would not be an orphan class. If there was place for hull reinforcement for operation in iced...

Might the USN be also targeting buying foreign (Japanese) boats? Should the RCN buy 12 of them, would earn lots of "bonus points" as a credible, reliable ally. https://www.19fortyfive.com/2023/07/the-u-s-navy-needs-diesel-electric-submarines-now/

I agree somehow with YZT580, however that should not be an issue during peacetime (maybe >90% of the time?) and would extend either the patrol time or the boat's life. I wonder if towing the boats could also work. In such a case the solution might be a mix of tender, towing and...

In the link below there is a 4 pages undated paper (2022?) from Vice-Admiral R. Davidson about Submarine procurement. Short but ticks many points. It brings up the concept of a Heavy Lift Ship for overseas deployments, which had been earlier raised in Starshell review (Aug. 2022)...

Regarding TKMS, fuel cells and batteries... https://www.navalnews.com/naval-news/2023/05/powering-the-future-tkms-submarine-battery-developments/

Sometimes journalists make mistakes when they don't have tech. background. The engines are diesel MTU 396 design. 3,500 KW electric motor .... ok 300 KW AIP .... ok (power of the fuel cell, reformer supposed to produce enough hydrogen for it) Bio-ethanol engines would not make sense because...

There will be four S80, actually S-81 to S-84. The first one, being in the last trials this year, and the second, are to be delivered without AIP. It will be installed in their 1st long-term overhaul (after about 5-6 years). It is expected the other two will be delivered with it. This AIP uses...

Sorry, late to edit my previous post. For the Type 212 CD should say Methanol (not ethanol) reformer.

Probably, but that means risks and high costs on such development. I don't know what happened with Slowpoke-3 but it's somehow warning the fact that only one was built and it operated for just a couple of years. @suffolkowner was not going nuclear in his post. I know for sure that both...

Still, it's only 20KW while Swedish submarines have 2x 75 KW Stirling engines. German AIP is about 250KW (2x 125) IIRC.
