AKA: A12. Status: Study 1956. Payload: 13,600 kg (29,900 lb). Thrust: 23,900.00 kN (5,372,900 lbf). Gross mass: 1,280,000 kg (2,820,000 lb). Height: 97.00 m (318.00 ft). Diameter: 20.00 m (65.00 ft). Apogee: 102 km (63 mi).

By 1956 Von Braun was just months away from the first launch of his Jupiter ballistic missile and sketching what would become the Saturn I launch vehicle. His design group clearly knew that any real launch vehicle would consist of simple cylindrical bodies. Fins had been entirely deleted on the Jupiter and Saturn designs.

However Von Braun, or his collaborator Willy Ley, did not bring their nominal space launch vehicle up to date. The design presented in print and television in 1955-1957 was simply a small-scale version of the 1952 design. The first and second stages were simply reduced to 20% of their former size. The expendable third stage was tiny, equivalent to the Agena stage then under secret development. Its main purpose was to maintain the burn-our velocity of the second stage as calculated in 1948. In this way the 1948 calculations could remain sub-orbital and recoverable. The manned glider became a separate payload, that could be replaced by an 'all cargo' module. The only nod to modernity was that the glider was now delta-winged, a better solution for a vehicle that had to be stable over a wide range of airspeeds.

LEO Payload: 13,600 kg (29,900 lb) to a 102 km orbit at 23.50 degrees.
