Sailors and Marines assigned to future amphibious assault ship USS America (LHA 6) walk into position to man the rails as the ship prepares to arrive in its homeport of San Diego for the first time. Their arrival marks the completion of a two-month transit around South America from Ingalls Shipbuilding in Pascagoula, Miss. America is the first ship of its class, replacing the Tarawa-class of amphibious assault ships. As the next generation "big-deck" amphibious assault ship, America is optimized for aviation, capable of supporting current and future aircraft such as the MV-22 Osprey and F-35B Joint Strike Fighter. The ship is scheduled to be ceremoniously commissioned Oct. 11 in San Francisco. (U.S. Navy photo by Mass Communication Specialist 1st Class John Scorza/Released)
