The IC Rating

Originally derived from the Electrician’s Mate rating, the Interior Communications Electrician rating was established in 1948.

The Navy’s computerized personnel system associates the rating name with an alphanumeric Navy Occupational Specialty (NOS) code. For IC, the NOS is B230.

Interior Communications Electricians direct and coordinate the installation, maintenance and repair of interior communications systems on ships and at shore facilities. These systems include communication systems, indicating and navigation systems, visual landing aids for aircraft, alarm, safety, and warning systems.

Interior Communications Electrician class “A” school is approximately 22 weeks long, and the school is located in the Center for Surface Combat Systems, Great Lakes, Illinois. At the completion of school, some interior communications electricians go on to advanced training courses such as gyrocompass and advanced TV maintenance. Others are assigned to duty stations where they can continue learning their rating through on-the-job training.
