One example is the ammunition system. At the touch of a keyboard, missiles and bombs for the aircraft are ordered up from the magazines deep in the ship, moving on computer-controlled sleds up through lifts to near the hangar deck where a human gets hands on them for the first time. Here they have fuses and fins fitted as they are “built” on what Capt Petitt likens to a “Model T Ford” production line, ready to be hung off aircraft.
