Robert Truax was one of the great originals of American rocketry and a major proponent and inventor of ultra-low-cost rocket engine and vehicle concepts. He became involved in rocket programs as a Naval officer during World War II. This work continued in the post-war Navy, culminating in a loan to General Schriever of the US Air Force from 1955 to 1958. During this period he was very active in studies (along with STL and other study agencies) of advanced ballistic missile and space-based weapons systems. This was in addition to his normal duties of running the Thor IRBM program. He refined some of his low cost launch concepts, but was not able to develop financial support within the Air Force. In 1959 he retired as a Captain, and came to Aerojet where he headed the Advanced Development Division until leaving in 1967. Here his low-cost booster program plan was elaborated and further studied, but he was again unable to interest NASA or the USAF in the concept of cheap access to space.
