They perform such tasks as preventive maintenance, testing of bomb racks, missile launchers, rocket launchers, handling equipment, loading equipment, aircraft guns for issue to squadrons, and perform any repairs needed. Depot "D" level is for equipment that needs to be completely overhauled and is beyond the capabilities of "I" level maintenance. In a 20-year period, an average aviation ordnanceman spends about 60 percent assigned to fleet units and 40 percent to shore stations. Defense

Aviation Ordnancemen are a close-knit community and one of the few ratings in the U.S. Navy to have their own association, the Association of Aviation Ordnancemen.
