ATK Plays Critical Role in Successful Standard Missile-3 Intercept

Alliant Techsystems provided the third-stage rocket motor (TSRM) and Solid Divert and Attitude Control System (SDACS) for the successful intercept test flight of the Raytheon Company’s Standard Missile-3 (SM-3). The SM-3 was launched from the Aegis Ballistic Missile Defense (BMD) Weapon System. The successful test destroyed a ballistic missile outside the earth’s atmosphere during an Aegis BMD Program flight test over the Pacific Ocean.

The February 24 mission — the fifth successful intercept for SM-3 — was the first firing of the Aegis BMD “Emergency Deployment” capability using operational versions of the SM-3 Block I missile and Aegis BMD Weapon System.

The SM-3 was launched from the Aegis BMD cruiser USS Lake Erie (CG 70) and hit a target missile that had been launched from the U.S. Navy’s Pacific Missile Range Facility on Kauai, Hawaii.
