A detail of the fuel-stained runway deck of the US Navy's Harry S Truman aircraft carrier whilst on exercise somewhere in the Persian Gulf. From this surface, $38 million F/A-18s fighters take off the ship's deck and into the air from a standing position. The angled flight decks of the carriers use a CATOBAR arrangement to operate aircraft, with steam catapults and arrestor wires for launch and recovery. The Truman is the largest and newest of the US Navy's fleet of new generation carriers, a 97,000 ton floating city with a crew of 5,137, 650 are women.
