Aerojet Rocketdyne Delivers 100th SM-3 Block IB TDACS

Aerojet Rocketdyne has delivered their 100th throttling divert and attitude control system (TDACS) to Raytheon.

These control systems are used for Raytheon’s SM-3 (standard missile-3) Block IB guided missile system. For something that is designed to blow things up, the missile control system is actually relatively safe due to its reliability and low-risk propulsion technologies.

It is used to support the third-generation of land- and sea-based US missile defense capabilities. The TDACS is top-of-the-line, and does not cost a fortune to make.

Our TDACS team has developed and deployed the most sophisticated and innovative solid rocket propulsion system in the world, delivering a stabilized production line of high quality TDACS that continue to deliver 100% mission success with continued affordability for our customers, stated Charlie Meraz, Aerojet Rocketdyne SM-3 TDACS program manager.

The SM-3 is a missile that is designed to “hit-to-kill.” It is produced as one of the United States Navy’s sea-based ballistic missile defense systems. It provides defense against medium and long range ballistic missiles by colliding with them.

In addition to that, Aerojet also provides the first two stages of booster motors used to power the Block IB kinetic warhead, guided by TDACS. This will allow them to increase the SM-3 Block IB missile’s capability against current and emerging target threat sets. The Block IB includes an infrared seeker and the actual control systems used to propel the missile.

Meraz also noted the importance of the 100th delivery in their long-established relationship with Raytheon.

The delivery of the 100th TDACS marks a significant milestone in the history of the SM-3 Block IB program and Aerojet Rocketdyne's valued collaboration with our long-time customer, Raytheon, in ensuring the defense capabilities of our nation.

Raytheon received a $559m contract in May from the Missile Defense Agency to deliver the US Navy's SM-3 Block IB all-up rounds.
