National Historic Mechanical Engineering Landmark Saturn V Rocket 1967-1973 The largest rocket built at the time of the historic first missions to the moon, the Saturn V carried aloft the 45-ton Apollo spacecraft on earth orbital and lunar missions from 1967 to 1972. It also launched the 120-ton Skylab into earth orbit on May 14, 1973. Design and fabrication of the Saturn V were carried out by a Government/industry team which included the National Aeronautics and Space Administration, the Boeing Company, North American Rockwell, McDonnell Douglas Corporation, International Business Machines, and their sub-contractors. Many of the design features were outgrowths of the earlier development work accomplished by military service organizations and their contractors.
