TKMS Type 212CD (Victoria class replacement megathread)

[Furniture]

Dominion Defense Review has a video on the subject as well.

I think it's a case of breaking a massive commitment into manageable bites, more than a case of backing out.

As much as we all like to think the dumb voter in (insert town here) is dumb, to get things done, the GoC needs to keep the dumb voters on side.

I agree that the intention right now. But we've all seen every country in the world lower their order numbers of expected equipment at one time or another. UK with the Type 26, Australia with the Hunter class, Germany with their own frigate program etc...

And as military watchers in Canada don't trust the governmet (or the electorate) with good reason, despite the click bait title, is a fair concern. But we're way to early to rush to judegment. IOC is expected in 2032, 6 years from now, so the decision on 4 more needs to be decided sometime in 2036? That's two governments away and a whole lot of technological growth, which could force a change (robot subs, Arpeggio of Blue Steel or whatever).

I know nothing of the industry but am surprised that they wouldn't use high frequency AC like large commercial aircraft (generally 400Hz) to save space and weight.

While that’s a common belief, 400 Hz by itself doesn’t save much weight, it is used for transformer efficiency and power supply purity. There is a minor weight savings.

Increasing working voltage saves weight because the lower amperage needed requires smaller, lighter conductors. The 115VAC saves more weight over 28VDC.

Edit to add: Interestingly more weight is saved on aircraft through digital control communications data is systems, fiber optic in particular. MIL-STD FAST1553 (wire) and 1773 (fiber) and ARINCs 664 (AFDX) and 818 (fiber). Trying to find the fact, but a 787 running AFDX avionics data-bus is hundreds of pounds lighter than an old ARINC 429 point to point avionics system.
