Hey Jeff, let me ask you a hypothetical question if I may. During a fight with a submarine when a torpedo exploded (not directly) near one of these giant propellers would it still be working?
Depends on lot of things. If a torpedo hit one of those propellers and detonated, it would probably ruin that propeller at least...but there are four and the vessel could keep going depending on the damage.
If the detonation penetrated the hull into the machinery spaces and caused larger destruction, fires and secondary explosions, it could stop the carrier.
But the nuclear carrier is FAST. If she has time to get up to max speed, which may be as high as 50 knots or more, she may outrin the torpedo. Aslo the US is developing counter torpedo torpedos to attack oncoming torpedos too.
