The Missile Defense Agency

Doing the Impossible for 24 Years


“MDA was established to bring alive a bold vision, one that required developing and delivering an initial operational missile defense capability into the hands of the Warfighter in two years, with increased capabilities to follow.... 'Go Fast, Think BIG' was in our DNA from the very beginning! And it’s exactly what our nation needs again today.” - MDA Director Lt. Gen. Heath Collins


The Missile Defense Agency (MDA) is a research, development, and acquisition agency within the Department of War. Our workforce includes government civilians, military service members, and contractor personnel in multiple locations around the world. We are focused on retaining and recruiting a dedicated workforce interested in supporting our national security.

As we develop, test, and field an integrated Missile Defense System, the MDA works closely with the combatant commands (e.g. Pacific Command, Northern Command, etc.) who will rely on the system to protect the United States, our forward deployed forces, and our friends and allies from hostile missile attack. We work with the combatant commanders to ensure that we develop a robust missile defense system technology and development program to address the challenges of an evolving threat. We are also steadily increasing our international cooperation by supporting mutual security interests in missile defense.

The MDA is committed to maximizing the mission assurance and cost effectiveness of our management and operations through continuous process improvement.
