General Dynamics [GD] has received a follow-on delivery order worth $16 million to provide Joint Service Lightweight Standoff Chemical Agent Detector (JSLSCAD) systems and spares for Stryker Nuclear, Biological and Chemical Reconnaissance Vehicles. The original six-year contract was awarded last year by the Army and runs through 2011. The JSLSCAD is the first chemical detection system with 360-degree coverage for ground vehicles and has a detection range of up to two kilometers. The technology uses a passive infrared detection system that automatically searches for chemical agent vapor clouds.
