AS-203 (also known as SA-203 or Apollo 3) was an uncrewed flight of the Saturn IB rocket on July 5, 1966. It carried no command and service module, as its purpose was to verify the design of the S-IVB rocket stage restart capability[3] that would later be used in the Apollo program to boost astronauts from Earth orbit to a trajectory towards the Moon. It achieved its objectives, but the S-IVB was inadvertently destroyed after four orbits during a differential pressure test that exceeded the design limits.[4]
