ATK and KEI Missile Defense Team Successfully Test Fire Second-stage Rocket Motor


Minneapolis, January 20, 2006 – Alliant Techsystems (NYSE: ATK) completed a successful test firing earlier today of a second-stage rocket motor for the U.S. Missile Defense Agency’s (MDA) Kinetic Energy Interceptor (KEI).

This is the first in a series of static motor firings leading up to the program’s first booster flight in 2008.

Northrop Grumman (NYSE: NOC) is leading the industry team charged with developing and testing a KEI capability under contract to MDA.
Raytheon Company (NYSE: RTN) is responsible for developing and integrating the KEI system’s interceptor.

The second-stage rocket motor burned successfully to completion,
demonstrating proof-of-concept of the motor assembly and its thrust vector
control nozzle for this high-acceleration, high-velocity, and highly
maneuverable missile. Initial test results matched expectations for rocket
motor performance and integrity.

KEI is a mobile, land-based missile defense system that, when deployed, will be able to destroy a hostile threat during its boost, ascent or mid-course phase of flight. ATK is the largest propulsion subcontractor on the KEI program. The company will produce first-stage rocket motors at facilities in Utah and will produce second-stage and third-stage rocket motors in Elkton, Md. The KEI canister launch eject gas generators will be produced by ATK in Rocket Center, W.Va.

ATK is a $3.1 billion advanced weapon and space systems company employing approximately 15,000 people in 23 states. News and information can be found on the Internet at
