new pilots of the Aviation Group No. 2 were able to transition from flying piston aircraft to jet aircraft on its own, ruling that the Air Force was ready to receive its first single seat jet fighters, Lockheed F-80C-10-LO Shooting Star. These aircraft arrived in 1958 and replaced the North American F-51D-20-NA Mustang in their mission. In 1959, at the initiative of Brigadier Conrado A. Saez, General Inspector of the Air Force at the time, the Uruguayan Military Air Transport (Transporte Aéreo Militar Uruguayo) was founded to complement the flag carrier First Uruguayan Air Navigation Lines (Primeras Líneas Uruguayas de Navegación Aérea) and provide passenger and cargo services to different cities in the interior of the country and also abroad. TAMU began operating Douglas C-47 Skytrain and would later use Fokker F27 Friendship, Fairchild-Hiller FH-227D, Embraer C-95 Bandeirante and CASA C-212 Aviocar of the Uruguayan Air Force. The service of the C-95 in Uruguay marked the first Embraer export in its entire history, when a total number of five of these brand new aircraft were purchased in 1975. The Air Force and the Uruguayan Dictatorship Since the end of the 1960s and the beginning of the 1970s, the Air Force was involved in the fight against the guerrilla activity that was present in the country, focusing against the MLN-T (Movimiento de Liberación Nacional – Tupamaros or Tupamaros – National Liberation Movement), that later triggered a participation in the country's politics. On February 8, 1973, President Juan María Bordaberry tried to assert his authority over the Armed Forces by returning them to their normal duties and appointing a retired Army general, Antonio Francese, as the new Minister of National Defense. Initially, the Navy of Uruguay supported the appointment but the National Army and Uruguayan Air Force commanders rejected it outright. On February 9 and 10, the Army and Air Force issued public proclamations and demanded his dismissal and changes in the country's political and economic system. Bordaberry then gave up to the pressure, and on February 12, at the Cap. Juan Manuel Boiso Lanza Air Base, Headquarters of the General Command of the Air Force, the National Security Council (Consejo de Seguridad Nacional) was created. The Commander-in-Chief of the Air Force was one of its permament members, and the Armed Forces of Uruguay from now on were effectively in control of the country, with Bordaberry just participating in a self-coup.
