Infrared countermeasures system prototype passes field tests
Apopka, FL--The Laser Systems business of Northrop Grumman (NYSE:NOC) said its All Semiconductor Airborne Laser Threat Terminator (ASALTT) infrared countermeasure (IRCM) laser system has advanced to Technology Readiness Level 6 (TRL-6), a government measurement system that includes nine levels. ASALTT is a quantum cascade laser-based mid-infrared laser developed to protect a variety of fixed-wing and rotor aircraft.
Following numerous environmental and field tests held at its Apopka facility and various sites throughout the country, the ASALTT system successfully passed a series of thermal, shock, vibration, and other field tests equivalent to 2,500 hours of field use. In addition, the ASALTT met all performance specifications for multiple IRCM platforms, including the UH-60, C-17, and C-130 aircraft.
The system was designed using MOSA Inside, a modular open systems approach (MOSA) to interior hardware and software that allows flexibility for upgrades. The architecture provides for a single laser output, using the best technologies available from laser diodes, interband cavity lasers, quantum cascade lasers, fiber and more traditional laser sources from the ultraviolet through long-wave IR bands.
