The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System. JAN) and the Joint Communications-Electronics Nomenclature System, is a method developed by the U.S. War Department during World War II for assigning an unclassified designator to electronic equipment. JETDS is described in detail by MIL-STD-196. Computer software and commercial unmodified electronics for which the manufacturer maintains design control are not covered. ==Usage== Electronic material, from a military point of view, generally includes those electronic devices employed in data processing, detection and tracking (underwater, sea, land-based, air and space), recognition and identification, communications, aids to navigation, weapons control and evaluation, flight control, and electronics countermeasures. Nomenclature is assigned to: * Electronic material of military design * Commercial electronic material that has been modified for military use and requires military identification and design control * Electronic material which is intended for use by other Federal agencies or other governments that participate in the nomenclature system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joint Electronics Type Designation System」の詳細全文を読む スポンサード リンク
