APOPKA, Fla., April 2, 2012 -- Northrop Grumman Corporation's (NYSE:NOC) Laser Systems business unit announced that 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.

The ASALTT™ is an advanced technology quantum cascade laser-based mid-infrared laser designed and developed to protect a wide variety of aircraft including fixed-wing and rotor aircraft, whether based on land or at sea.

The system was designed using "MOSA Inside™," a modular open systems approach (MOSA) to interior hardware and software that allows great flexibility for upgrades. The MOSA Inside™ 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 infrared bands.

"With field-proven capability, and the TRL-6 maturity, ASALTT™ is ready for integration into the next generation of aircraft-deployed counter-MANPADS systems," said Gordon Stewart, vice president and general manager of Northrop Grumman Laser Systems. "We are confident that ASALTT™  is ready to support flight testing and will greatly enhance IRCM system effectiveness, performance and protection of the warfighter."

Northrop Grumman Laser Systems has delivered more than 25,000 Electro-Optic (EO) laser systems units and is one of the world's leading manufacturers of military EO targeting systems. These include ground-based (man-portable, handheld and vehicle-mounted) EO imaging/ranging systems for target location, laser designators/markers for precise guidance of smart munitions, and airborne laser rangefinders and designators fielded onboard many of the world's most sophisticated manned and unmanned aircraft.
