Contact: Patrick Louden Tel: (561) 796-6793 Web Site: www.pw.utc.com Pratt & Whitney Space Propulsion – Mk-72 The Mk-72 booster is the latest addition to the STANDARD Missile Family, providing the SM-2 Block IV (AEGIS ER) the maximum capability in altitude and range. The first anti-air warfare missile system for fleet defense was initiated over 40 years ago. It has evolved from its origin as a wing-controlled beam rider to its present state as the most advanced supersonic tail-controlled semi-active RF homing missile. Integrated with the Mk-41 Vertical Launch System (VLS), the Block IV provides wide area coverage for the new generation of AEGIS missile cruisers. The Mk-72 provides not only the initial boost, but also complete steering for the missile including pitch, yaw and roll control. The fournozzle thrust vector control (TVC) is unique for tactical missiles. Pratt & Whitney Space Propulsion’s San Jose, Calif., site developed the Mk-72 under contract to Raytheon Company in cooperation with a team which included the U.S. Navy and Hughes. The motor is the largest booster developed for launch from the Mk-41 Vertical Launching System (VLS). The booster is currently in production under contract to Raytheon Missile Systems Company, which is now responsible for all STANDARD Missile production. The Mk-72 is also the first-stage booster for the Navy’s Ballistic Missile Defense systems. The Mk-72 provides the Navy a high performance, extremely agile booster as the building block for all new missile initiatives, ensuring off-the-shelf compatibility with the VLS. Characteristics Diameter: 21 inches Length: 68 inches Total weight: 1,500 pounds TVC system: 4 movable nozzles Actuation: Electromechanical
