|precision = |power = }} The Western Electric M-33 Antiaircraft Fire Control System ("M-33 fire-control system", "Antiaircraft Fire Control System M33", "AA FCS M33") was an X-Band "Gunfire Control Radar", for aiming antiaircraft artillery by computer control. Developed for mobility via 3 trailers, the "M-33 system could compute, for the 90-mm. and 120-mm. guns, firing data for targets with speeds up to 1,000 mph", and for targets at 120,000 yards had similar gun laying accuracy as "SCR-584 type radars" at 70,000 yards. The system included a telescopic "target selector" on a tripod near the guns for additional measurement of aircraft "azimuth and elevation data () be transmitted to the computer and utilized as gun directing data." The M-33 was deployed overseas and as part of the CONUS "manual air defense system" for which Army Air Defense Command Posts telephoned foe aircraft information to the M-33 units which used its surveillance board to mark targets using grease pencil. ==Development and deployment== In 1944, the US Army contracted for an electronic "computer with guns, a tracking radar, plotting boards and communications equipment" (M33C & M33D models used different subassemblies for 90 & 120 mm gun/ammunition ballistics.) The "trial model predecessor" (T-33) was used as late as 1953,〔 (reprinted in p. 53〕 and the production M33 (each $383,000 in 1954 dollars) had been deployed in 1950. The 34th AAA Brigade's 90mm guns were converted to the M-33 by December 3, 1954, after the 95th AAA Brigade had been upgraded. Aberdeen Proving Ground〔 (the announcement for the Army Air Forces radar school to move from Boca Raton to Keesler Field was in late May 1947.)()〕 and Fort Bliss were (training posts for M-33 personnel ), and by 1957 there were 3 Ordnance Detachments in Germany for M33 Integrated Fire Control Repair—150th (Wiesbaden), 151st (Mannheim), & 152nd (Kaiserslautern) Ord Det (IFCR);〔Stars and Stripes (newspaper), January 30, 1957〕 and functional test sites included the White Sands Proving Ground ranges (e.g., "Hueco Range No. 3). The M33 was also used for satellite tracking in 1961. 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「Western Electric M-33 Antiaircraft Fire Control System」の詳細全文を読む スポンサード リンク
