Smiths Detection has been placed with a task order to provide for the US Department of Defense’s (Dod) joint chemical agent detector (JCAD) programme.

The $30m order for the enhanced M4A1 JCADs brings the total awarded contract to $350m under the long-running JCAD programme.

The M4A1 JCAD, based on Smiths LCD 3.3, is an advanced, detect-to-warn device that protects troops by sampling the air for chemical warfare agents and toxic industrial chemicals.

The device weighs less than 2lb and can be worn or carried by troops without obstructing their primary duties.

The company has also recently expanded its facility, partly to help meet demand from the US military for the JCAD programme.
