The Convair X-12 being launched
The Convair X-12 was the second, more advanced testbed for the Atlas rocket program. It was designed with 3 engines, its predecessor the Convair X-11 used only one engine. It was powered by a 1.5 stage liquid-fuel rocket. Its first flight was in July, 1958.
Service history
The X-12 pioneered the use of 1.5 stage rocket engines that became a hallmark of the Atlas rocket program. It was also the first rocket to achieve a flight distance that could be considered intercontinental when it flew 6,325 miles.
Five X-12 rockets were built and five flights were made out of Cape Canaveral, but no X-12s are believed to have survived.

Von Braun became director of the Army Ballistic Missile Agency at Redstone Arsenal and developed the Redstone/Jupiter rockets that launched the U.S.'s first satellite and first man in space. As NASA was created, the western part of Redstone Arsenal became NASA's Marshall Space Flight Center.
Von Braun became director at Marshall and directed the development of the Saturn V that sent Americans to the moon. The Titan II and Atlas rockets also played significant roles in the NASA manned space program. Mercury was powered by Redstone (designated Jupiter for launch missions) and Atlas rockets, Gemini by Titan II, and Apollo by Saturn rockets.
The key to the Atlas design is an extremely lightweight structure, conceived largely by an inventive Convair engineer, Karl J. Bossart. The missile's frame consisted of a very thin-gauge stainless-steel skin that maintains its shape and structural integrity only from the high pressure inside its propellant tanks. If the tank pressurization failed, the skin would crumble and the launch vehicle would collapse under its own weight. Many engineers, including famed rocket designer Wernher von Braun, worried that the Atlas' design could not survive the intense aerodynamic stresses placed upon it the early phases of launch, so much so that von Braun's design team derisively referred to the Atlas as a �blimp� or their �inflated competition.�
