After arriving in North Carolina, the group resumed a split operation when the 538th and 529th Squadrons moved to Bluethenthal Field, North Carolina after they were organized . The Army Air Forces was finding that standard military units, based on relatively inflexible tables of organization were proving less well adapted to the training mission. Accordingly, it adopted a more functional system in which each of its bases was organized into a separate numbered unit. As a result, in 1944 the group was disbanded as the AAF converted to the AAF Base Unit system. The 123d AAF Base Unit (Replacement Training Unit, Fighter) replaced the group headquarters and squadrons at Seymour Johnson, and the 130th AAF Base Unit (Replacement Training Unit, Fighter) replaced the squadrons at Bluethenthal Field.
