The USS Enterprise is a ship with the largest number of nuclear reactors. How many does she have?
Most American aircraft carriers are powered by two reactors. The only exception was the early-constructed USS Enterprise, having an eight-reactor propulsion design, with each A2W reactor taking the place of one of the conventional boilers in earlier constructions. Enterprise was meant to be the first of a class of six, but construction costs ballooned and the remaining vessels were never laid down. The design was replaced by two-reactor Nimitz class.
