Questions tagged [saturn-i]

Questions related to the Saturn I and Saturn IB launch vehicles, the USA's first medium lift launch vehicle and predecessor to the Saturn V. The Saturn I and IB are 2-stage vehicles. Both have the same first stage with 8 H-1 engines and a distinct appearance due to the clustered fuel tanks. The Saturn I had a S-IV second stage with 6 RL-10 engines, the Saturn IB had the same S-IVB stage used on the Saturn V with a single J-2 engine.
