My favourite submarines (by USSR) :
Typhoons
Intercontinental nuclearstrike submarine, he's the biggest submarine in the world : 25 000 Tons (As US aircraft carrier during WWII).
It's also the US submarine's nightmare : perfectly quiet...

Delta IV Delphin : Intercontinental nuclearstrike submarine, he's perfectly quiet and stealth !
