1Title:  Launching Glenard P. Lipscomb: Nuclear powered electric drive submarine Add
 Summary:  The program from the launching of the USS Glenard P. Lipscomb, which was powered by the S5W reactor plant and employed an electric drive propulsion system to achieve noise reduction. Instead of a steam-driven propulsion plant with reduction gears converting the high-speed efficiency of the turbine to the lower speed of the shaft and screw, an electric motor was used to drive the submarine. The program's text describes the two basic thrusts of naval nuclear propulsion development in the late 1960s and early 1970s. First, the development of a high-speed submarine, the 688 (Los Angeles) class; second, the development of a submarine focused on noise reduction - the Lipscomb, using the electric drive system. The Lipscomb was the only submarine built in its class; as historian Francis Duncan notes, the electric propulsion system was larger and heavier than the components in the steam-driven propulsion plant.
