The National Air Force of Angola or FANA () is the air branch of the Armed Forces of Angola. With an inventory of more than 300 aircraft, FANA is (on paper) one of the largest and strongest air forces of Africa. History Angola became independent from Portugal on 11 November 1975. However, the foundations for the establishment of the air force were laid before independence when members of the then Flying Club of Angola () were assembled at Luanda in October 1975. These people and aircraft left behind by the Portuguese Air Force formed the basis for the air transport branch of the force. The force was formally established on 21 January 1976 as the People's Air Force of Angola / Air and Antiaircraft Defense or FAPA/DAA (). Its first batch of Soviet MiG fighter aircraft was delivered in mid-December 1975. The FAPA/DAA fought several battles with South African Air Force aircraft in November 1981, October 1982, and twice in September 1987. Circa 1983–85, in order to enhance MPLA's combat capacity, Romania sent 150 flight instructors and other aviation personnel, who contributed to the establishment of an Angolan Military Aviation School. The FANA has bases at Luanda, Catumbela, Belas, Luena, Kuito, Lubango and Moçâmedes. The World Factbook, produced by the CIA, reported that by 2007 the name of the force had changed to "National Air Force". Most of the inventory is out of service, and refers to historical equipment delivered along the years. FAN has many bases – most of them, former Portuguese Air Force bases and other courtesy of the Cold War – but few airplanes that actually fly. The main body of the active air force is made of transport/cargo planes, used for moving supplies, equipment and personnel between parts of the country. Structure The National Air Force of Angola is headed by the Chief of Staff of the FANA (). The Chief of Staff of the FANA is a General directly subordinate to the Chief of the General Staff of the Armed Forces of Angola. FANA follows a Russian/ex-Soviet organizational model, with its air units being aviation regiments (), each one including several squadrons (). To each of the six aviation regiments corresponds an air base. Besides the aviation regiments, there is also a Pilot Training School. Its order of battle is: 25th Fighter Aviation Regiment (Kuito Airport) 13th Fighter Squadron (Su-27 and Su-27UB) 12th Fighter Squadron
