I just seeing that now. Still not clear if that’s a modified Virginia or really new.
The VA isn’t anything to to sneeze at, I’d think. The Columbias should be far more capable than the Russian Borei’s of similar size. I’d probably best the Columbias will be 5-25 times quitter? US Sub have always vastly outperformed their Russian counterparts.
Main thing is, I bet both sides would delivery sub strikes on every major city on the others’ sides almost equally as well.
