the Russians claim that the “double hull enables her to take three direct torpedo hits to sink”

Has the US Navy ever tested that theory?

I remember in the 80’s the Brits sent an Argentine warship (a cruiser, fromerly CL-46) to the bottom with a pair of WWII vintage torpedos.

You mean HMS Conqueror sinking the ARA General Belgrano (ex-USS Phoenix CL-46) in the Falklands War?

The General Belgrano was a cruiser, not a cruise missile submarine. The hulls of surface vessels and subs are different.

USN torpodeos are not impacting design, modern torpodoes detonate directly beneath the target causing a massive pressure wave under the target hull cracking it almost in two.
