84th Radar Evaluation Squadron The 84th Radar Evaluation Squadron is a component of the 505th Operations Group , 505th Command and Control Wing , Air Combat Command , stationed at Hurlburt Field , Florida . The squadron provides the Warfighter responsive worldwide radar - centric planning , optimization , and constant evaluation to create the most sensitive integrated radar picture . Overview . The 84 RADES provides expert assistance to multiple government entities : from radar coverage studies to crucial assistance for search and rescue coordination centers . It insures that tactical and strategic air defense ground radars , C2 systems , and electronic resources are installed , maintained , and operated in a high state of readiness to provide a quick reaction to the threat of both limited and general wars . The squadron also regularly provides assistance to the USAF Safety Center , US Navy Safety Center , and National Transportation Safety Board . The Radar Data Interface System ( RDIS ) , designed and built by 84 RADES engineers and present at all Air Defense Sectors and Alaska , drives our Event Analysis ( EA ) process . EA is a post - event investigation of aerial mishaps that has provided a unique and sometimes crucial perspective on a high number of military and civilian aircraft incidents . History . The squadron was activated by Air Defense Command ( ADC ) in 1952 as the provisional 4754th Radar Evaluation Electronics Counter - Countermeasure Flight , assigned to the Western Air Defense Force ( WADF ) at Hamilton AFB , California . The mission was to provide Electronic Counter - Measure ( ECM ) training and evaluation services to the various Aircraft Control and Warning Squadrons of WADF . In order to provide the necessary training for WADF , the 4754th was assigned six B - 29 Superfortress es , three B - 25 Mitchell s , and one C - 47 . The B - 29s and B - 25s contained an assortment of jamming devices to provide the required ECM and the C - 47 was used as a support aircraft to ferry personnel and equipment . During the period that the 4754th operated these aircraft , they provided the operators of the WADF with thousands of hours of ECM training . By 1958 , the size of the unit was increased to 59 officers and 206 airmen – a growth of 58 % in four years . Effective 8 July 1958 , the ADC re - designated the unit as the 4754th Radar Evaluation Squadron ( ECM ) . By 1959 the World War II aircraft were very expensive to operate , needing excessive amounts of maintenance to remain airworthy and not supportable due to a lack of spare parts . The squadron ' s aircraft were retired and the squadron was moved to Hill AFB , Utah . The unit was given sole responsibility for providing evaluation services to all AC & W type radars and radar systems throughout North America . The squadron was initially placed under Central Air Defense Force ( CADF ) , but transferred shortly afterward to ADC ’ s 29th Air Division in 1960 and then the 28th Air Division in 1961 as a result of ADC reorganizations . For the next 14 years , the unit evaluated all long - range air defense radar facilities , standardized evaluation processes , and developed new evaluation technologies . During this time , the command of the squadron was transferred to ADC ' s 4th Air Force in 1966 and to ADCOM Headquarters in 1969 . The unit ’ s exemplary performance was noted in 1968 when it received its first of 21 Outstanding Unit Awards . By 1975 , the unit had been given the responsibility for Pacific ( PACAF ) and European ( USAFE ) radars , making it the only ground based radar evaluation unit in the Department of Defense . In 1979 as part of the inactivation of Aerospace Defense Command , the unit was re - designated the 1954th Radar Evaluation Squadron , and was transferred to the Air Force Communications Command , then headquarterd at Richards - Gebaur Air Force Base , Missouri . The squadron was designated 84th Radar Evaluation Squadron in 1987 and was transferred to Tactical Air Command , and in 1992 it became part of the newly formed Air Combat Command , following TAC ’ s inactivation . The RADES maintained its alignment under the USAF Warfare Center until 1993 , when they became part of the 505th Command and Control Evaluation Group . In July 1998 , the unit became a charter member of the newly formed Air Combat Command Communications Group , based at Langley AFB , VA . Finally , in October 2005 , the 84th RADES returned to the USAF Warfare Center , under the 505th Command and Control Wing and 505th Operations Group based in Hurlburt Field , Florida .
