Navy Enlisted Rating (Job) Descriptions and Qualification Factors

Interior Communicationman (IC)

By

Interior Communications Electricians (ICs) install, maintain and repair the equipment needed for interior communications within ships and shore facilities. These communication systems include public address systems, interior telephone systems, alarm systems, engine telegraphs to communicate orders for changes in engine speed from the bridge (ship's command station) to the engine room, certain kinds of ship control and equipment monitoring devices, the ship's gyrocompass, the rudder position indicator, audio-visual equipment for the ship's TV entertainment systems, advanced navigation and various other equipment.

The duties performed by ICs include:

  • maintaining and repairing interior communications systems;
  • preparing and interpreting blueprints, wiring diagrams and sketches;
  • installing and inspecting dry cell and storage batteries;
  • recharging wet cell batteries;
  • testing interior communications and gyrocompass equipment;
  • installing telephone and other communications circuits, boxes, switchboards and bell buzzer systems;
  • maintaining plotters and dead reckoning equipment;
  • maintaining and operating TV systems;
  • maintaining and repairing shipboard navigation equipment.

Working Environment

People in the IC rating work in many different situations, at sea and ashore. While most of their work is performed indoors, it may be in a clean or dirty environment of a shop-like nature, and it may be in any kind of climate or temperature. IC's usually work closely with others. Most systems IC's work on is of the modern solid state electronic type, making the rating a very technical profession.
