The United States Coast Guard 270 Foot Medium Endurance Cutter (WMEC-270) will be utilized primarily for search and rescue, off shore fishery patrols, enforcement of laws and treaties, and military readiness operations. To achieve reduced personnel manning without any reduction in the mission effectiveness, automation was incorporated into the ship's design. A computer based data processing system termed Command, Display and Control System (COMDAC) was selected to collect and process input data from ship's sensors (radar, fathometer, visual, etc.) and to present real-time, processed information in a readily usable format. This information is presented to various COMDAC console monitors in a TV raster display which allows for superpositioning one display over another (i.e., a digitized chart overlaid on a radar presentation). Some navigational computer-assisted methodology utilized by COMDAC is dead reckoning, automatic target acquisition and tracking, visual positioning and plotting, and collision avoidance. The operators can interact with COMDAC via keyboard entry, function switches and trackball cursor controls. This provides the operators the flexibility of monitoring more dynamic data displays in a shorter time frame than they have previously been able to do.
