I can't vouch for the author at all, but this seems like a nice detailed, technical look at the difference between the two.

TL;DR the 212CD is very good at what in biology would be called "sit and wait predation". It's designed to sneak into an ocean floor crevice and hang out there, possibly for for weeks until something comes by, and then attack it. The Hanwha offering, on the other hand, is less superlatively stealthy and maneuverable, but is much more flexible, allowing missile launches and likely having a much longer range.

"Land-attack capability via cruise and/or non-nuclear ballistic missiles"

Canada needs nukes.

[–] CanadaPlus@futurology.today 5 points 2 days ago

Yeah, I was wondering why that was specified. I spent some time looking into if it could fire nukes as well this morning. The verdict is maybe; a lot is secret, but the kind of tubes the KSS-III has are thought to be larger than their ship-borne equivalent.

Ukraine made a deal with America to disarm back when America was a little trustworthy. Things have changed, and I say they're good to resume nukes.

Ukraine's independence from USSR, included constitutional neutrality and no nukes. US was not main negotiator.

Close.Ukraine made a deal with Russia to return their nukes in exchange for non-invasion with US and European signatories as guarentors. (Because Russia has never been trustworthy.)

It's why Nato supplying Ukraine is legitimate. Russia renegged on the non-invasion treaty knowing full well what happens.

Edit: Ukraine has no nuclear building capabilities in the short to medium term. Long term , who knows?

It's more like "everyone needs no nukes". It's just that being one of the nuclear powers is so much easier...

Having a delivery system in case we do decide to go down that path seems reasonable.

I don’t think Canada is in a place where it needs to have a nuclear weapon. There are no threats to Canada (besides Trump, and we know that’s not likely). Canada doesn’t need to lower itself to those levels.

Do we? Sometimes he TACOs, but sometimes he does exactly what he said he would. And what about whoever the next American autocrat is?

Getting in on one of the European umbrellas would be much better, though. We could even have British or French warheads on a Canadian sub, although I doubt it could launch a Trident as the delivery system.

[–] velindora@lemmy.cafe 1 points 1 day ago

Trump isn’t trying to take over Canada. He’s focused on making money for himself. If he puts a single foot in Canada the rest of the world is going to shun the states (even more). It’s pointless.

Imo, Canada doesn’t need weapons of mass destruction.

It used to be nobody needs nukes, but...since our most powerful ally is the only nuclear power stupid enough to actually use them we get the deterrent value anyway. As client states we were all (UK, Australia, Canada etc) actively discouraged from developing independent capabilities that would reduce our dependency on the alliance or US arms industry.

If people found the US nuclear umbrella re-assuring then, many don't now. I am Australian, but submarines and the US alliance are a huge issue here as well.

Canada's geography is very important strategically to the USA like practically no other place. Canada has less need of nukes than just about anyone. Currently the fate of other US allies feels far less secure. It seems we are all just bits of land to be traded to our enemies by the US administration in return for who knows what? It is a very sad state of affairs.

A nuclear weapon is only as good as the resolve to use it
