An Aviation Electronics Technician (AT) aboard USS Constellation (CV 64) repairs a multiple-matrix switch card. Modern aircraft depend on radio, radar and other electronic devices for rapid communications, effective navigation, controlled landing approaches and neutralizing enemy equipment and tactics. ATs are responsible for the test, maintenance and repair of this equipment. AT is one of more than 60 job specialties found in today's Navy. Constellation is currently on a regularly scheduled deployment supporting Operations Southern Watch and Enduring Freedom. U.S. Navy photo by Photographers' Mate 3rd Class Prince Albert Hughes III.
