Background . performing a medical evacuation during the war in
Portuguese Guinea. The Portuguese Army maintained its own aviation arm from 1914 to 1952. This arm received a high degree of autonomy in 1937, including its own separate chain of command, although continuing to be administratively connected to the Army. In the early 1950s, the decision was taken to completely separate it from the Army, becoming an entirely independent
branch of the Armed Forces. The decision was also taken to separate the
Portuguese Naval Aviation from the Navy and to put it under the control of the new independent air branch. The new branch created in 1952, became the
Portuguese Air Force, unifying all the Portuguese
military aviation assets and operations under a single command. During the
Portuguese Overseas War (1961–1974), all military air assets were part of the Air Force. These were employed both in independent operations and in cooperation with the land and naval forces, under the coordination of the joint military commands. The Air Force was equipped with assets oriented for the counter-insurgency, including new
helicopters that were used to perform joint
helicopter operations involving
Commandos and
Paratroopers (these then being part of the Air Force). Occasionally, the Air Force established detachments of cooperation that operated under the command of Army units. == Aircraft procurement ==
