World War II

319th Bomb Group B-26s take off

The group was activated as the 514th Air Service Group in late 1944, absorbing its personnel and equipment from the 306th Service Group^[1] as part of a reorganization of Army Air Forces (AAF) support groups in which the AAF replaced service groups that included personnel from other branches of the Army and supported two combat groups with air service groups including only Air Corps units. The group drew its personnel and equipment from the disbanded 306th Service Group^[1] The 514th was designed to support a single combat group.^[2] Its 940th Air Engineering Squadron provided maintenance that was beyond the capability of the combat group, its 764th Air Materiel Squadron handled all supply matters, and its Headquarters & Base Services Squadron provided other support.^[2] The 514th supported the 319th Bombardment Group in Italy, then returned to the United States for transfer to the Pacific Theater.^[1] The group sailed from Naples, Italy to Boston, Massachusetts. Upon arrival in the United States members of the group received 30-day leaves, following which the group reassembled in South Carolina.^[1]

The 514th staged through Fort Lawton, Washington and the Caroline Islands before arriving on Okinawa.^[1] The unit performed same mission on Okinawa as it had in Italy. The group was awarded credit for participation in the Ryukus Campaign.^[3] It was disbanded in 1948.^[4]

The 514th was redesignated as an air defense group, reconstituted and activated at Minneapolis-St Paul International Airport in 1953.^[5] with responsibility for air defense from its base in the upper midwestern United States. The group was initially assigned the 18th Fighter-Interceptor Squadron, which was already stationed at Minneapolis-St Paul, where it flew World War II era North American F-51 Mustangs,^[6] as its operational component.^[7] The 18th had previously been assigned directly to the 31st Air Division. The group replaced the 72d Air Base Squadron as host active duty USAF unit at Minneapolis-St Paul Airport. It was assigned three squadrons to perform its support responsibilities.^[8][9]
