The reactor was intended for use aboard USS John F. Kennedy. This four-reactor design was intended to reduce the cost involved in the construction and operation, as compared with the Enterprise and its eight nuclear reactors.
Early in the construction, the United States Secretary of the Navy had the plans changed to save money, and fossil fuel boilers were installed on the Kennedy. Because the plans for the ship did not include a funnel, the funnel on the Kennedy protrudes out from the ship at an angle.
The return to nuclear power for carriers came with the Nimitz class's A4W reactor's two reactor per ship design. While the two reactor configuration, with each core providing a much greater thermal output, is relatively less expensive than earlier designs, the power plant still represents about half the total cost of the ship.
