One-Stop Propulsion Shop

摘要

Aerojet was not involved in the big mergers that realigned the U.S. space propulsion industry in the last five years, but the Sacramento, Calif., company emerged from the upheaval as the only one active in all segments of the business. Alliant Techsystems purchased Thiokol to become the top U.S. supplier of large solid-rocket motors, while Pratt & Whitney bought Boeing's Rocketdyne division to assume a similar position in liquid-fueled engines. Aerojet is the main competition for both companies, and also builds in-space propulsion systems for satellites.
