Forca Aerea Brasileira (FAB) Brazilian Air Force

HistoryOrganizationEquipment'Força Aérea 100'Brazilian military aviation began on 13 January 1913, when the Brazilian School of Aviation was founded. On 2 February 1914, the school began operations at Campo dos Afonsos near Rio de Janeiro with three Farman biplanes and five Blériot monoplanes that it had purchased from Italy. Organized under the Minister of War, the school was to train aviators for the Army and Navy. The Brazilian Air Force had not always been a separate and coequal member of the countrydefense establishment. Like the United States Air Force, it had its beginnings in the Army, and it was World War II that provided the impetus for its separation and independence. In the late 1930s and early 1940s, U.S. leaders watched events unfolding in Europe and looked Southward as they considered possible threats to national security. Hemispheric defense was the watchword of the day, and Brazil figured significantly in the calculations of that defense. The United States needed to deny possible hostile nations a foothold...Get price
