The470th Electronic Warfare Group is an inactiveUnited States Air Force unit. It was last active as a crew training unit duringWorld War II as the470th Bombardment Group atTonopah Army Air Field, Nevada, where it was disbanded on 31 March 1944. In 1985, the group was redesignated as anelectronic warfare unit, but has not been active since then.
In January 1944, the group moved toTonopah Army Air Field, Nevada in echelons with the 802d Squadron leading the way on 3 January 1944, followed by the 803d Squadron on 4 January, the 801st Squadron on 5 January, and groupheadquarters and the 800th Squadron completing the group's move on 6 January.[1][2] The move to Tonopah also marked a transfer toFourth Air Force, and a mission change to become aReplacement Training Unit (RTU). RTUs were oversized units like OTUs, but their mission was to train individualpilots oraircrews.[3] However, theArmy Air Forces found that standard military units like the 470th, based on relatively inflexibletables of organization were not well adapted to the training mission. Accordingly it adopted a more functional system in which each base was organized into a separate numbered unit.[4] The 470th Group and its four squadrons were disbanded on 31 March 1944,[1][2] and along with support units at Tonopah, replaced by the 422 AAF Base Unit (Bombardment Replacement Training Unit – Heavy).
^It is unclear what type of aircraft the group used for training. InAir Force Combat Units of World War II, Maurer states the group was aConsolidated B-24 Liberator training unit. Maurer,Combat Units, pp. 344–345. However, inCombat Squadrons of the Air Force, World War II, he indicates that each of the group's four squadrons was equipped withBoeing B-17 Flying Fortresses. Maurer,Combat Squadrons, pp. 761–762.
