ATK has been awarded a $52.7 million contract from the Missile Defense Agency (MDA) to continue development of Modular Divert and Attitude Control System (MDACS) technologies applicable to the Standard Missile-3 (SM-3) Block IIB missile interceptors. The technology contract will be executed by ATK Defense Group's Elkton, Maryland operation.

The MDACS propulsion system provides the impulse needed for the kinetic warhead to acquire and lock onto the target, maintain stable flight and perform end-game maneuvers for final intercept.

Specific technologies to be advanced will include elements of the new MDACS system architecture to address the longer mission timelines associated with growing threats. ATK's unique approach to a ship-board compatible MDACS improves the SM-3 Block II kinematic performance, providing a key performance upgrade to the missile.  

“We are excited for the opportunity to work with the MDA to continue to develop the MDACS propulsion technology suite. We look forward to applying our unique technical expertise in controllable solid propulsion solutions for this critical defense capability,” said Cary Ralston, Vice President and General Manager of ATK Missile Products.

ATK has produced more than 165 solid DACS (SDACS) for the SM-3 program. ATK has more than 35 years of experience in developing and manufacturing missile defense DACS and has built a strong engineering team dedicated to driving innovative solutions for future interceptors.
