CASTOR 30 family

Northrop Grumman CASTOR 30 family is a vectorable-nozzle, in-line solid upper-stage motor family. The CASTOR Motor Series catalog describes CASTOR 30 as a low-cost, robust, commercially developed upper-stage motor designed to function as a second or third stage, identifies CASTOR 30B as a production derivative with a propellant change and longer nozzle, and identifies CASTOR 30XL as a stretched derivative. The catalog reports that CASTOR 30, CASTOR 30B, and CASTOR 30XL have each flown on Antares missions supporting International Space Station resupply. Individual model specifications, production status, and installations remain on the exact child records.
