O.C. DIVISION OC Division consists of two work centers, OCOl and 0C02. OCOl is composed of the Radiomen whose job is to use electronic equipment to communicate to other ships and naval stations around the world. 0C02 is composed of the Signalmen whose job is to communicate to other ships using the following methods: Flags, signal lights and semaphore (hand movements) to convey messages to other ships within sight. OCOl DIVISION OCOl Division, the Radiomen rating, a part of the Com- munications Department, operates voice and Teletype cir- cuits. Radiomen provides communications capabilities to other parts of the ship, CIC, Bridge, Sonar and helo tower. Radiomen use three basic methods of communications, radio Teletype, voice and international Morse code. The most com- monly use is radio Teletype, they processed an average of 600 to 800 messages a day during the deployment to the Persian Gulf. With state of the art, high tech communications equip- ment, radio was able to keep communications going through- out the ship as well as provide other divisions with informa- tion about the world as well as providing the crew with sports scores.

Lipperd The signalmen rating, the art of visual com- munications, is one of the oldest in the Navy. Its origins are traced back to the days of sail and wind, when wooden ships of the English, French and Spanish fleets used flags and signal lanterns to communicate with one another. Today signal- men in the U.S. and Allied navies use three basic methods of communications. Flashing light, either directional or non-directional, is the most common means of transmitting messages be- tween ships, and employs the international Morse code to distinguish alphabetical, numeri- cal and punctuational equivalents. Semaphore, the use of arm positions, with or without hand held flags, is the most secure means of visual transmission because of its speed and its charac- teristic short range nature limits the possibility of interception. Flaghoist, the preferred method of transmitting tactical signals between ships within visual signaling range, employs numerous combinations of alphabetical, numeral and spe- cial flags and pennants to construct a wide vari- ety of signals derived from publications intended for use in allied military and international com- munications.
