Well well, Leaderwolf, actually that isnt the fastest submarine ever built. Here, i
present to you, K222 "Papa" class:
here is the wiki article on it.
http://en.wikipedia.org/wiki/Soviet_submarine_K-222
This thing got up to 44.85 knots! 3 knots faster than the alpha. The alpha is
generally regarded as the fastest and deepest diving sub ever, even though it was
exceeded in both areas by the K222 and the K278.
Adamai, i think that Vanguard class is incredible!
although i have to say, the Alpha is quiet an astonishing looking boat as well!
