S-band RADAR Designations From February 1943 the US used a universal system to identify radar variants, consisting of three letters and a number, respectively designating platform, type of equipment, function, and version. This system was continued after WWII with multiservice designations being prefixed by 'AN/' for Army-Navy. BuShips 1943 classifications Multi-service classifications Multi-service classification codes according to the Joint Electronics Type Designation System.
