1 Just because at this point the quietest submarine in the world certainly isn't an Ohio class boat.

According to the world's foremost authority on military hardware, Tom Clancy, the Ohio class uses convection currents to allow coolant to circulate through its reactor whereas every other nuclear boat has relatively noisy pumps instead. Therefore they are quietest. This is why they are 10 knots slower than an SSN of similar vintage, but then it's more important for them to hide than run.

Voting 3. Shame we can't confirm whether we got the Kilo or not...
