on 14 March 1951. RADC The "Rome Air Development Center" headquarters officially opened on June 12, 1951, with the personnel of the headquarters for the 2751st Wing and 3171st & 3151st groups, which were "discontinued"—the 6530th Air Base Wing with subordinate units, e.g., Maintenance and Support Group, activated on the same date for support through August/November 1952. RADC was for USAF "applied research, development and test of electronic air-ground systems such as detection, control, identification and countermeasures, navigation, communications, and data transmission systems, associated components, and related automatic flight equipment". RADC constructed the Forestport Tower in 1951 for low-frequency communications experiments. On 1 January 1953, RADC reorganized into the Engineering Support Division, Electronic Warfare and Techniques Division, Equipment Development Division, and Systems Division (a Plans and Operations Office at the HQ provided guidance.) For ATC and SAC to score bombing accuracy, and based on the AN/MPQ-2; RADC integrated AN/MPS-9 radars with RBS plotting to create the AN/MSQ-1 (with OA-132 plotting computer/board)) and AN/MSQ-2 (OA-215)—RADC also developed SAC's "AN/GSA-19 Blanking System" for safety at RBS radar stations. RADC began using a new intelligence and reconnaissance laboratory building on 27 May 1954, and an AN/GPA-37 "developed by RADC [and] installed at the Verona Test Site" conducted a 28 December 1955 ground-controlled interception test "on an F-86D fighter interceptor aircraft". Also in 1955 RADC developed phased array radar technology, and the center contracted Bendix's Radio Division in 1958 to build the Bendix AN/FPS-46 Electronically Steerable Array Radar (ESAR) for demonstration (1st "powered up" in November 1960.) A prototype AN/FPS-43 BMEWS radar completed at Trinidad in 1958 went operational on February 4, 1959, the date of an Atlas IIB firing from Cape Canaveral Launch Complex 11 (lunar reflection was tested January–June 1960.) On 20 January 1960 RADC accepted the Avco AN/FPS-26 Frequency Diversity Radar from Avco for use at SAGE radar stations (later modified into the 474N "Fuzzy-7" SLBM Detection Radar.) AFCCDD assignment On 1 July 1960, RADC was assigned to the Air Force Command and Control Development Division and , RADC conducted an "Experimental Passive-Satellite Communication Link" using the ECHO satellite and Philco terminals for reflecting voice transmissions through space from the Trinidad Space Communication Facility (with "BMEWS type radar tracker" using "AN/FRC-56 type" transmitter and "84FT DISH") to the "RADC Floyd Site". In August 1962, RADC established the "AFLC Communications-Electronics Field Office" to monitor missile tests. A "60-foot-diameter" antenna at the Floyd
