The 1962 United States Tri-Service aircraft designation system is a unified designation system introduced by the United States Department of Defense on 18 September 1962 for all U.S. military aircraft. Prior to this date, the armed services used separate nomenclature systems. Under the 1962 system, almost all aircraft receive a unified designation, whether operated by the United States Air Force (USAF), United States Navy (USN), United States Marine Corps (USMC), United States Army, or United States Coast Guard (USCG). Experimental aircraft operated by manufacturers or the National Aeronautics and Space Administration are also often assigned numbers in the X-series.〔 The 1962 system was based on the one used by the USAF between 1948 and 1962 which was in turn based on the USAAS/USAAC/USAAF system used from 1924 to 1948. Since it was introduced, the 1962 system has been modified and updated; in 1997 a revised form of the system was released.〔(Designating and Naming Defense Military Aerospace Vehicles ), U.S. DoD, 14 March 2005.〕 ==Designation system== The designation system produces a ''Mission-Design-Series'' (MDS) designation of the form: :(Status Prefix)(Modified Mission)(''Basic Mission'')(Vehicle Type)-(''Design Number'')(''Series Letter'') Of these components, only the ''Basic Mission'', ''Design Number'' and ''Series Letter'' are mandatory. In the case of special vehicles a ''Vehicle Type'' symbol must also be included. The U.S. Air Force characterizes this designation system as "MDS", while the Navy, and Marine Corps refer to it as ''Type/Model/Series'' (T/M/S).〔http://www.navair.navy.mil/napra/〕 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「1962 United States Tri-Service aircraft designation system」の詳細全文を読む スポンサード リンク
