Model: Improved Orion-1. Gross Mass: 400 kg (880 lb). Thrust (vac): 13.000 kN (2,922 lbf). Burn time: 32 sec. Propellants: Solid. Diameter: 0.35 m (1.14 ft). Length: 1.80 m (5.90 ft). Country: USA. No Engines: 1. Motor: Orion. Status: Active. First Flight: 1990. Last Flight: 2007. No Launched: 101. Used as: Orion. Other designations: Orion. Release conditions: Aerojet. The Improved Orion motor was a bi-phase propellant system that results in thrust levels of approximately 84.5 kN during the first four seconds of motor burn then trailing off to approximately 13.3 kN until burnout around 25 seconds. The fins were generally configured to provide a burn out spin rate of four cycles per second. Used on Launch Vehicles:
