The second carrier in the USS Gerald Ford class, the USS John F. Kennedy, seen here in a photo illustration, is under construction by Newport News Shipbuilding.<br /> <br />The keel of the vessel was laid in August at the Virginia shipyard, and the builder reports that 450 of the ship's 1,100 structural units have been made since work began in 2010.<br /> <br />The Navy said in June that it expects the cost for the Kennedy to come in below the Ford, as some cost savings were identified in the process of building the first ship in the class.<br /> <br />
