470th Bombardment Group
# 470th Bombardment Group

The 470th Electronic Warfare Group is an inactive United States Air Force unit. It was last active as a crew training unit during World War II as the 470th Bombardment Group at Tonopah Army Air Field, Nevada, where it was disbanded on 31 March 1944. In 1985, the group was redesignated as an electronic warfare unit, but has not been active since then.

## History

The 470th was first activated by Second Air Force at Mountain Home Army Air Field, Idaho in May 1943 to serve as a heavy bomber training unit. The group's operational squadrons were the 800th, 801st, 802d, and 803d Bombardment Squadrons. The group initially acted as an Operational Training Unit (OTU). The OTU program involved the use of an oversized parent unit to provide cadres to "satellite groups".

In January 1944, the group moved to Tonopah 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 group headquarters and the 800th Squadron completing the group's move on 6 January. The move to Tonopah also marked a transfer to Fourth Air Force, and a mission change to become a Replacement Training Unit (RTU). RTUs were oversized units like OTUs, but their mission was to train individual pilots or aircrews. However, the Army Air Forces found that standard military units like the 470th, based on relatively inflexible tables 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. The 470th Group and its four squadrons were disbanded on 31 March 1944, and along with support units at Tonopah, replaced by the 422 AAF Base Unit (Bombardment Replacement Training Unit – Heavy).
