AKA: Renova. Status: Study 1963. Payload: 423,000 kg (932,000 lb). Thrust: 140,540.00 kN (31,594,640 lbf). Gross mass: 9,154,600 kg (20,182,400 lb). Height: 59.00 m (193.00 ft). Diameter: 21.30 m (69.80 ft). Apogee: 185 km (114 mi).

Martin Marietta's "Renova" design featured rocket engines enclosed in an air duct equipped with adjustable inlets. The conical payload fairing would serve as an inlet spike during the ascent through the atmosphere. The air (which is heated by the rocket exhaust) would contribute additional thrust as it expands past the plug-shaped afterbody. The inlets would be closed after leaving the atmosphere.

LEO Payload: 423,000 kg (932,000 lb) to a 185 km orbit.
