On 2 September 1975, the Canadian Forces transferred the air assets of all commands to a newly formed Air Command (AIRCOM). Air Defence Command and Air Transport Command were abolished. In their place, Air Defence Group and Air Transport Group were formed and made subordinate to Air Command. The air assets of Maritime Command were transferred to a newly formed Maritime Air Group. Air training became the responsibility of a newly created 14 Air Training Group and the air assets of Mobile Command were transferred to a newly formed 10 Tactical Air Group. No. 1 Canadian Air Group was formed in Europe to control all air assets there. AIRCOM closely resembled the old RCAF as the new command handled all the aviation requirements of Canada's military.
