American orbital launch vehicle. A winged recoverable Saturn IC stage was considered instead of solid rocket boosters after the final shuttle design was selected.

Status: Study 1972. Thrust: 33,737.90 kN (7,584,582 lbf). Gross mass: 3,161,710 kg (6,970,370 lb). Height: 107.00 m (351.00 ft). Diameter: 10.06 m (33.00 ft).

In yet another iteration of shuttle design studies, $ 2.8 million contracts were given in November 1971 to Grumman/Boeing, Lockheed, McDonnell-Douglas/Martin Marietta, and North American Rockwell. The development costs for the Phase B Prime contracts had still been over the Nixon administration's budget cap, and still further ways to reduce development cost had to be found. The studies were to run through 15 March 1972 and study lower cost booster concepts, one of them a Saturn V first stage modified to serve as a flyback booster. The study concluded that a Saturn S-IC flyback booster would need a wing with at least a 700 sq m area, would be powered by five F-1 engines and have a gross mass of 1.6 million kg. Staging would take place at 6450 kph. The vehicle would be reusable, except for the F-1 engines. The use of expendable engines was considered a drawback. The study assumed a series burn, with the shuttle orbiter igniting at altitude.

Flyaway Unit Cost 1985$: 1,020.500 million.
