Convair X-12

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 liqued-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.
