Juno V
The Juno V series of rockets were a design that was proposed in the late 1950s but cancelled. The rockets were multi-stage and, although they failed to reach production, their sections were used in other designs. The Juno V was an eight-engine cluster concept, requiring second and third stages to make a complete booster. Depending on the stages added, the rocket would either be a Juno V-A or a Juno V-B.
