AN/KAS-1 Chemical Warfare Directional Detector (CWDD)

AN/KAS-1 CHEMICAL WARFARE DIRECTIONAL DETECTOR (CWDD) The AN/KAS-1 CWDD illustrated in figure 2-16 is a passive device, two fields of view, forward- looking infrared system used by the Navy for standoff detection of nerve agents. The unit can be bracket-mounted on a ship’s signal bridge or tripod mounted. It is used: (1) as a chemical warfare advance warning system and (2) for surveillance and navigation and search and rescue operations during hours of darkness, periods of limited light visibility, and during daylight operations. The AN/KAS-1 weighs approximately 27 pounds and has a range of 3200 yards. It is powered by 115 volts ac, 60 hertz at 36 watts. Its field of view is 3.4 X 6.8-degrees wide and 1.1 X 2.2-degrees narrow. MAINTENANCE Most maintenance on laser equipment is pre- ventive maintenance only (i.e., clean and inspect) and can be completed with little-to-no problems. Correc-tive maintenance is primarily limited to the depot level. Therefore, if you experience a major problem with laser equipment, you must send it to the Naval Surface Warfare Center, Crane, Indiana, for repair. Throughout this chapter, we have introduced laser devices that are in use in the Navy today. This area of technology is continually expanding. As it does, your knowledge of this area should also grow. This volume has introduced you to a small amount of the night vision equipment and laser devices that are used in today’s Navy. Remember to follow all safety precautions when using these equipments. Your eyes cannot be replaced. 162.1 Figure 2-16.—AN/KAS-1 CWDD tripod-mounted. 2-10
