Abstract : The Spirit II Launch Vehicle System was launched successfully from Poker Flat Research Range on 28 March 1992. All flight objectives were achieved and a peak altitude of 326 Km achieved. The vehicle liftoff weight was 20,092 pounds. The first stage, powered by the Talos motor, boosted the vehicle to an altitude of 6000 feet. The first stage experienced minor wind disturbances. The second stage, Aries motor (a surplus solid propellant motor from the Minuteman I missile), performed as predicted. The inertial guidance system achieved the pre- programmed burnout conditions. The spent second stage impacted 157 Km uprange.
