"Enterprise Air Group" not "Air Group 6."
Air groups were not numbered until June 1942 with the creation of CVG-9 on the east coast at NAS Norfolk and CVG-10 on the west coast at NAS San Diego.
In the actions around the Solomons, until the arrival of Air Group 10 aboard Enterprise in October 1942, the air groups in action were the Saratoga Air Group, Enterprise Air Group, Wasp Air Group, and Hornet Air Group - or SAG, EAG, WAG, and HAG in the vernacular.
Air Group 6, as a designated organization, was not established until 15 March 1943.
