Soviet Typhoon Class, the biggest submarine ever made (there's a man on the deck)

Capt. Vasili Borodin: I will live in Montana. And I will marry a round American woman and raise rabbits, and she will cook them for me. And I will have a pickup truck... maybe even a "recreational vehicle." And drive from state to state. Do they let you do that?
Captain Ramius: I suppose.
Capt. Vasili Borodin: No papers?
Captain Ramius: No papers, state to state.
Capt. Vasili Borodin: Well then, in winter I will live in... Arizona. Actually, I think I will need two wives.
Captain Ramius: Oh, at least.

40,000 tons submerged i believe. Damn monster is the size of a battleship.

they were going to make these "stealth" subs for the Australian navy, as large as this, but the problem is, even if you can't see it on radar or sonar, you can spot it easily from the air due to it's size
