Castor (rocket stage)


The Castor family of solid-fuel rocket stages and boosters built by Thiokol (now Orbital ATK) and used on a variety of launch vehicles. They were initially developed as the second-stage motor of the Scout rocket. The design was based on the MGM-29 Sergeant, a surface-to-surface missile developed for the United States Army at the Jet Propulsion Laboratory.
