I. IntroductionII. Philippine Army Air CorpsIII. The War YearsIV. The Philippine Air Force and The Post-War Years[VIEW THE PHOTO GALLERY: The Philippine Air Force Visual History] The Philippine Air Force (PAF) began as the Philippine Army Air Corps (PAAC). It was officially established as a separate branch of the Armed Forces of the Philippines (AFP) on July 1, 1947 through Executive Order No. 94, s. 1947under the administration of President Manuel Roxas. However, the PAF’s origins can be traced back as early as 1917, during World War I. In 1916, the passage of the Jones Law in the U.S. Congress was a momentous event for the Philippines. Through the law, the pledge of eventual independence—once Filipinos were ready for self-governance—was made. The Jones Law led to the creation of an all-Filipino legislature composed of the Philippine Senate and House of Representatives. At the time, the Constabulary and the U.S. Army remained at the forefront of the country’s defense under the U.S. War Department. Filipinos were also at first generally barred from joining the Constabulary. But civil positions...Get price
