Proposed growth variant of the heavy-lift version of the Atlas V launch vehicle with three parallel 3.8-m-diameter Common Core Boosters (CCB), a 5-m-diameter wide body version of the Centaur upper stage with a single-engine, and a 5 m diameter payload fairing. Another variant would use a stretched wide body version of the Centaur upper stage with 2 or 4 motors, allowing payloads of up to 13,500 kg to be lofted to earth escape velocity.

Manufacturer: Convair. Payload: 12,000 kg (26,000 lb). to a: earth escape trajectory. Liftoff Thrust: 11,470.000 kN (2,578,550 lbf). Total Mass: 960,000 kg (2,110,000 lb). Core Diameter: 3.81 m (12.49 ft). Total Length: 60.00 m (196.00 ft). Span: 11.50 m (37.70 ft).
