Hughes Jarvis launcher would use technology from Saturn, Shuttle

The proposed Jarvis medium launch vehicle (MLV) would incorporate Saturn propulsion system features and structures and STS electronic systems. The MLV would be 205 ft tall, 27.5 ft in diam, and would be capable of placing 85,000 lb into LEO or 17,500 lb into GEO. The all-liquid fueled booster could place up to six GPS satellites simultaneously or carry two GPS satellites into LEO and two communications spacecraft into GEO on the same launch. The first and second stages, built with tooling for the External Tank, would be powered by Saturn F-1 and J-2 engines, respectively. The kerosene/oxygen fuel burns would provide 3 M1b thrust. Fully-redundant avionics systems would be completely tested on the launch pad, which could be located at Vandenburg, Cape Canaveral, or Johnston Island in the Pacific Ocean. Development of the MLV is dependent on Air Force procurement of the capability.
