Ah, that makes sense. It’s like when the car dealer shows you the version of the car you want with slightly different features since the one you want isn’t on the lot yet.

That’s an attack sub (for attacking ships/other boats), not a boomer (which have nukes).

Weird that they specify “conventionally powered” in the Canadian article since this is a nuclear powered sub.

Only congress can declare “war”, but as far as I know, that hasn’t happened since WW2. The president just does what they want.
