Saturn IB
One KC-97 airframe (AF Ser. No. 52-0828) was adapted into the Aero Spacelines Super Guppy, a transport plane designed specifically to support the Apollo Program by carrying Saturn IB and Saturn V upper stages across the country (California to Florida). The aircraft carried the Saturn S-IVB stage, which served as the second stage of the Saturn IB, the third stage of the Saturn V, and the fourth stage for the never-built Nova rocket.
