In the early 1990s, AIRCOM transport and utility helicopters in support of army operations were cut back and consolidated with the purchase of the CH-146 Griffon, replacing the CH-135 Twin Huey, CH-136 Kiowa, and CH-147 Chinook.
On 1 July 31, 1997, all previous groups were eliminated and placed under No. 1 Canadian Air Division/Canadian NORAD Region.
