The 478th Fighter Group (USAAF) was a home based training unit that served as a replacement training unit.
The group was constituted as the 478th Fighter Group on 12 October 1943 and activated on 1 December 1943. It was assigned to the Fourth Air Force in the US South-West, but it took several months to gain the required personnel and equipment. The group thus didn't become operational until March 1944, when it began work as a replacement training unit for the P-39.
On 31 March 1944 the group was disbanded as part of a reorganisation of USAAF training units, and some of its personnel formed the basis for the new 432rd AAF Base Unit (Fighter Replacement Training Unit, Single Engine), based at the same airfield at Redmond, Oregon.
