329th Armament Systems Group The 329th Armament Systems Group is an inactive United States Air Force unit , last assigned to the Air Armament Center at Eglin AFB , Florida . It was inactivated in 2007 . History . World War II . The group was activated in 1942 under Fourth Air Force as the 329th Fighter Group , with the 330th , 331st , and 332d Fighter Squadron s assigned . At first , the group was primarily a replacement training group training P - 38 Lightning pilots in the final phases of fighter pilot training before shipping overseas . In November 1942 , the 337th Fighter Squadron returned to the US from Iceland and was assigned to the wing . The group ' s squadron s were dispersed for most of this period , stationed at various locations in California and Washington . The group also provided cadres for fighter groups , starting in early 1943 . During 1943 , its 330th Fighter Squadron also served as an air defense unit . The group was disbanded in 1944 and its personnel and equipment transferred to the 442d AAF Base Unit ( Replacement Training Unit , Fighter ) as part of an Army Air Forces ( AAF ) reorganization in which units not programmed to deploy overseas were replaced by AAF Base Units in order to free up manpower for overseas assignment because standard military units , based on relatively inflexible tables of organization were proving less well adapted to the mission . Accordingly a more functional system was adopted in which each base was organized into a separate numbered unit . Cold War . The group was reconstituted in 1955 as the 329th Fighter Group ( Air Defense ) and activated by Air Defense Command ( ADC ) as part of Project Arrow , which was designed to bring back on the active list the fighter units which had compiled memorable records in the two world wars . The group replaced the 4700th Air Defense Group at Stewart AFB and absorbed the 4700th ' s personnel and equipment . The 330th Fighter - Interceptor Squadron ( FIS ) was reassigned to the 329th , and the 331st FIS replaced the 539th FIS , which moved to McGuire AFB , New Jersey , since another purpose of Project Arrow was to reunite fighter groups with their traditional squadrons . The group was tasked with air defense of upper Northeast United States ( 1955 – 1959 ) flying radar equipped and rocket armed F - 86 Sabre s . The group also served as the host organization for all USAF units stationed at Stewart and was assigned a number of support organizations to fulfil this mission . In December 1956 , both of the group ' s squadrons began to receive upgraded Sabres equipped with data link communications equipment to interface with the Semi Automatic Ground Environment ( SAGE ) air defense system . The group was reduced to a single operational squadron in August 1958 , when the 331st FIS moved and was reassigned . In July of the following year , its remaining operational squadron was inactivated and the group and its support squadrons followed the next month . Modern Era . In 2006 , the group was reactivated and consolidated with the Air Combat Support Systems Group , which had been established as a systems development group at Eglin AFB , Florida as part of the Air Force Materiel Command Transformation , which replaced traditional program offices with named wings , groups , and squadrons . Starting in 2006 , these named units were consolidated with World War II groups and wings and assumed their numbers . The group was inactivated in 2007 , when the Air Armament Center reduced and realigned its systems units and its subordinate squadrons transferred to other armament systems groups .
