The vehicle featured a Centaur upper stage, the first such stage to use high-performance liquid hydrogen as fuel. Launches were conducted from Launch Complex 36 at the Cape Canaveral Air Force Station (CCAFS) in Florida.

The vehicle would be continuously developed and improved into the 1990s, with the last direct descendant being the highly successful Atlas II.
== Early development == Convair, the manufacturer of the Atlas, developed the Centaur upper stage specifically for that booster, sharing its pressure-stabilized tank structure.
