Excalibur
Credit: Truax Engineering
American sea-launched orbital launch vehicle. Excalibur was a subscale version of Sea Dragon proposed by Truax Engineering in the 1990's. It featured the same attributes as Sea Dragon: low cost design (pressure fed engines), Lox/Kerosene first stage (combustion chamber pressure 24 atmospheres) and Lox/LH2 second stage (chamber pressure 5 atmospheres). Guidance would be by a combined Inertial/GPS system. An even smaller Excalibur S vehicle would prove the concept and place 500 kg in orbit.
LEO Payload: 55,000 kg (121,000 lb) to a 230 km orbit at 90.00 degrees.
Status: Design 1992.
Gross mass: 2,366,500 kg (5,217,200 lb).
Payload: 55,000 kg (121,000 lb).
Height: 120.00 m (390.00 ft).
Diameter: 10.67 m (35.00 ft).
