Juno V-A

Juno V-A was studied in 1958, as a new name for the Super-Jupiter rocket. The only difference was that the rocket's first stage wouldn't have 4 E-1 engines, which were developed in 1957, but were cancelled and paved the way for the F-1 engine, which was used on the Saturn V rocket which took men to the moon. Instead, the Juno V-A would use the first stage of a Saturn I launcher to propel it into space and a whole Titan I ICBM to continue the journey. Juno V-A was never developed, but all its stages were used on different launch vehicles, now retired as of today.

Juno V-B

Juno V-B, studied in the same year as Juno V-A, was proposed for lunar and interplanetary missions into space. It was just like the Juno V-A, except the third stage, originally the second stage of a Titan I booster, would be replaced with a Centaur C high-energy third stage. A year after Juno V-B's study, the booster received a new name: the Saturn A-1, which, like the Juno series of rockets was never built, but all its stages used on different launch vehicles, now retired as of today.
