The sled was propelled by a four-stage sled train. A Super Roadrunner (SRR) rocket motor, developed specifically for the HUP program, powered each of the last two stages. The SRR motor produces 228,000-pounds of thrust for 1.4 seconds and only weighs 1,100 pounds. The maximum acceleration of the sled was 157-g's or 157 times the force exerted by gravity. When the payload impacted the target it had 363 megajoules of energy or the energy of a car impacting a brick wall at 2,020 miles per hour.
