Jupiter

Background

Juno II was derived from the USAF Jupiter missile and used as a launch vehicle in the 1950's and 60's for Pioneer and Explorer satellites. Not to be confused with Juno I, which was derived from the US Army Redstone-Jupiter-C missile development programme, it did nevertheless use the same Sergeant (Vicenza) upper stage, though sometimes ommitting the fourth stage to allow for extra payload capacity. Juno IVA and IVB were concept designs that were never flown, having been made obsolete by the introduction of the more capable Atlas launch vehicle.
