Displacement: 16,000 to 19,000 tons
Combat Radius: Limited only by onboard stores for personnel
Armament: Torpedoes, Tomahawk missiles, and a bevy of nuclear bombs
Analysis: Still said to be one of the keys to US defense, the Ohio class has global range and remains undeterred by above-ground attacks.
That independence is key. Without offshore nuclear-strike ability by the US, a gutsy enemy may think a land-based strike could take out American nuclear abilities. Ohio-class subs make that impossible.
