Another group was organized overseas in 1920 to administrate squadrons in the Philippines. In 1921, the three groups based within the United States were sequentially numbered one through three and assigned different combat roles. The fourth was inactivated. The next year the groups overseas were numbered four through six as "composite" groups. In 1922 plans were formulated for three more groups to flesh out the anticipated GHQ Air Force, but only one, the 9th Observation, was formed. The 7th Bombardment and 8th Fighter Groups were designated but not activated until the end of the decade.
