other young Army officers, Adhemar Saenz Lacueva and Esteban Cristi, the school that was formed was the only military aviation facility in Uruguay until 1935, and used several European aircraft types in fairly large numbers before American aircraft became the most predominant ones. During the twenties, and among them, were sixteen Avro 504K, thirteen Breguet 14, five Castaibert 913-IV and twenty-eight Nieuport 27. These pioneering years saw many air routes opened and an overall increase in the awareness of the aviation with military potential. Aeronáutica Militar In 1935 the Military Aeronautics (Aeronáutica Militar) was established and transformed the military aviation of Uruguay into a more professional weapon of the National Army. New units and airbases were created, and also new and more modern aircraft types were introduced into service. Among the aircraft used during this period were de Havilland DH.82 Tiger Moth and IMAM Ro.37. At the beginning of 1935, the Uruguayan Army suppressed an armed movement against Gabriel Terra government by members of different political factions. Military operations such as the Battle of Paso de Morlan and the bombardment of revolutionary positions with Tiger Moth aircraft meant the first combat use of military aviation in Uruguay. Then, during 1942 Curtiss SNC-1 Falcon and North American T-6 Texan training aircraft began their service in Uruguay, as did the Beechcraft AT-11 Kansan and Douglas C-47 Skytrain in 1947. Between 1949 and 1950 a total number of 39 aircraft were acquired, including 25 North American F-51D-20-NA Mustang, 11 North American B-25J-25-NC Mitchell and 3 Douglas C-47A Skytrain. With the help of the United States via the Military Assistance Program (MAP), these aircraft allowed the military aviation of Uruguay to grow not only in size but in training. Creation of the Uruguayan Air Force On December 4, 1950, with Law No. 12070, the Military Air Force (Fuerza Aérea Militar) was created as a separate branch of the Armed Forces. All the elements of infrastructure, material, aircraft, personnel and items belonging to the Military Aeronautics were transferred to the new Air Force, as it was established in the first article of the law. The second article of this law established the creation of the General Inspection of the Air Force (Inspección General de la Fuerza Aérea), which under the immediate authority of the Ministry of National Defense, became the direct command of the Military Air Force.
