Studied with the Saturn A-1 in 1959,[1] the Saturn A-2 was deemed more powerful than the Saturn I rocket. It was proposed as a launcher for Project Horizon, a scientific / military base on the Moon project, at a time when the U.S. Department of the Army, Department of the Navy, and Department of the Air Force had total responsibility for U.S. space program plans.[2][3][4]

The rocket consisting of a S-IB first stage with eight H-1 engines (which actually flew on the Saturn IB), a Jupiter Cluster second stage equipped which four LR79 engines (used on the Jupiter IRBM) and a Centaur C high-energy liquid-fueled third stage with a double RL10A-1 engine.[5]
