This massive mobile 'city at sea' centres around the hangar bay, flight deck, primary flight and air traffic controls, from which the Reagan's primary objective is achieved: the launch and retrieval of legions of multi-million dollar strike fighter jets. The entire crew, from the Captain and X.O to the aircraft, fuel and weapons handlers to the chefs, medics and garbage men keep this super carrier afloat and in perfect working order. Below deck, top secret nuclear power reactors are housed alongside the corridors, barracks and mess halls that provide a home away from home for the 5,000 men and women aboard.
