For the Department of Homeland Security's Counter-Man-Portable Air Defense Systems (C‑MANPADS) Program, Northrop Grumman created a cross-industry team to migrate Northrop Grumman's existing, proven military directional infrared countermeasures (DIRCM) technology for commercial application. With over 40 years experience in protecting lives and aircraft from the MANPADS threat, Northrop Grumman leads the team in the design of the DIRCM system technology. Our team also includes an airline partner with more than 30 years of experience in modifying commercial aircraft to FAA standards. They are responsible for developing the aircraft modification design, installation, and certification. In addition, one of our partners includes a premier airline with worldwide operations, offering tremendous experience in developing operation, maintenance, and support plans commensurate with standard airline operations. Together, the Guardian™ System team works in close partnership with the Department of Homeland Security Science and Technology Directorate on all aspects of the program.
