Joint Chemical Agent Detector (JCAD)

The Joint Chemical Agent Detector (JCAD) is a hand-held device intended to automatically detect, identify, quantify, and warn users of the presence of nerve, blister, and blood chemical agents. JCAD will be fastened to the operator's load-bearing equipment or mounted on a ground vehicle, aircraft, or ship. JCAD is used as a mobile and fixed-site monitor, as well as a quick-responding survey instrument. JCAD's ability to detect extremely low levels of agent concentration will be used in shelter and aircraft operations. The system operates as a stand-alone detector, as part of a small local network of other JCAD units, or can interface with the Joint Warning and Reporting Network as part of a larger network of biological and chemical detectors.

JCAD's hardware consists of the main detector unit (DU); an accessory for extending the limit of the DU (named the Preconcentrator); and an interface cradle that connects the DU with external power, external alarms, and other DUs to form a local network. All Services will use one basic DU configuration. JCAD will replace or augment existing Serviceunique chemical agent detectors.

The Air Force is JCAD's lead Service material developer, while the Army is the lead Service developmental and operational tester and evaluator. A combined Milestone I/II decision in December 1997 allowed JCAD to enter into Engineering and Manufacturing Development (EMD). Phase I of the EMD contract was awarded to BAE Systems in February 1998 and the Phase II contract option was exercised in April 1999. DOT&E placed JCAD on oversight in January 2000.

DOT&E approved the updated Operational Requirements Document in March 2002. Due to problems in the development of the Preconcentrator accessory, there will be a separate Milestone C review and IOT&E for the UD and accessory unit. The current schedule calls for the DU Milestone C in June 2004 and IOT&E beginning in 2QFY05. The Preconcentrator accessory scheduling is still in formulation. The Test and Evaluation Master Plan is currently being staffed through the Services.
