The Naval Combat System Simulator (NCSS) provides functionality for training communications operators beyond the traditional sensor operator training. As with the sensor operators, the functionality enables instructors to train operators across basic to advanced levels of proficiency. Operators are trained in the remote tuning of transmitters and receivers, circuit allocation, communications planning and emission control (EMCON). Operator performance is recorded for use by the instructor to identify areas requiring further training, to provide effective feedback on case studies and to contribute to lessons learned.
