In December, Raytheon completed the preliminary design review of the SM-3 Block IIA’s throttleable divert and attitude control system. The SM-3 Block IIA is a co-development effort between the U.S. and Japan and the cornerstone of phase three of the administration’s Phased Adaptive Approach.
“The TDACS is the most complex component of the SM-3 Block IIA,” said Wes Kremer, vice president of Raytheon Missile Systems’ Air and Missile Defense Systems product line. “The design detail and test data presented at the PDR demonstrated the TDACS is ready for the next phase of development.”
Made by Aerojet, the TDACs is essentially a rocket motor with four main divert nozzles and six attitude control nozzles. The system’s precision propulsion is what enables the SM-3 Block IIA to intercept incoming ballistic missiles with pin point accuracy.
The SM-3 Block IIA preliminary design review for the full system takes place March 19 to 23.
