Aviation electronics technician (AT) is a US Navy enlisted rating or job specialty (often called MOS or AFSC by other services).

[citation needed] Aviation electronics technicians wear the specialty mark of a winged helium atom.

Effective 2 April 1948 the name of the rating became aviation electronics technician (AET); the abbreviation was changed to (AT) on 9 June of the same year.

Billy C. Sanders, the fifth Master Chief Petty Officer of the Navy, first served as an aviation electronics technician.

They are the technicians that connect the component to a test bench to simulate an aircraft, and troubleshoot and repair the equipment.

I-level AT's are usually assigned to fleet readiness centers on shore or Aircraft Intermediate Maintenance Departments aboard ships.

O-level technicians troubleshoot various discrepancies with the use of multimeters and avionics test equipment to locate faults within the aircraft.

As electronics have migrated into other aircraft systems (such as flight control and weapons control), the IWT team is given the duties of maintaining specifically the armament and weapons systems, whereas a separate AT workcenter is responsible for non-weapons based electronics such as communications and navigation.
