"Chemical, biological, and radiological (CBR) weapons continue to pose a threat to U.S. Navy ships in the global war on terror. Shipboard Collective Protection Systems (CPS) provide defense against this threat on ships throughout the U.S. Naval fleet. CPS provides a nearly transparent layer of defense with a limited maintenance burden on the crew as compared to other systems aboard ship. The Shipboard CBR Protection Branch of the Naval Surface Warfare Center, Dahlgren Division (NSWCDD) has sought to reduce the maintenance and manning burden of CPS through a number of completed and ongoing projects. Although the number of ships employing CPS continues to increase throughout the fleet, the maintenance and manning burden for CPS will continue to decrease through persistent research and development efforts."
