all our nuclear subs are faster than all of our surface ships.
How fast are they? That’s classified
“all our nuclear subs are faster than all of our surface ships.”
Bullshit.
The crew can handle high speeds better is the only advantage.
Our boats have a speed "in excess of 20 knots", to quote Admiral Hyman Rickover. No comment on which subs I've been on or which subs from other navies I've heard (or seen), except that if you were anywhere within a large radius of Alpha or Papa you definitely heard them.
