Vermont Composites of Bennington has completed the delivery of the first production shipset of transmitter support structure and fairings for the Northrop Grumman NEMESIS Directional Infrared Countermeasures (DIRCM) system.
The DIRCM system is a joint program for the U.K. Ministry of Defense and the U.S. Special Operations Command.The Northrop Grumman DIRCM system is currently being installed on both U.K. and U.S. operational military aircraft. The system sensors detect missile launches and send the detection and location information to the tracking sensors. The tracking sensors track the missile and direct a narrow beam jamming signal at the missile to defeat the infrared threat. The Northrop Grumman DIRCM system provides C-130 aircraft with improved infrared missile defense. For the U.S. Special Operations Command the system will be installed on all of the Air Force Special Operations Command’s AC-130 gunships and MC-130 Combat Talon aircraft.
The composite fairings and mounting structure are fabricated by Vermont Composites (VCI) utilizing both carbon and glass fiber reinforced epoxy materials, providing strong, lightweight structures. The composite material is placed in molds and processed in an autoclave producing components with excellent structural integrity and product consistency. VCI assembles the transmitter structure by a combination of adhesive bonding and bolting. The structure is shipped to Lockheed Martin Systems Integration – Owego ready for installation on the aircraft.
