Surgeon General of the United States Air Force
In September 1947 the combat elements of the Army Air Forces separated from the U.S. Army, forming the United States Air Force. But a few Air Force support functions, such as medical care, remained U.S. Army responsibilities for the next two years. Starting in 1948, the Air Force and the Air Surgeon, Maj. Gen. Malcolm C. Grow (1887-1960), began to convince the U.S. Army and the administration of President Harry S. Truman that the Air Force needed its own medical service. In the summer of 1949, Air Force General Order No. 35 established a medical service with the following officer personnel components: Medical Corps, Dental Corps, Veterinary Corps, Medical Service Corps, Air Force Nurse Corps, and Women’s Medical Specialist Corps.
United States Army Air Forces
Following the successful German invasion of France and the Low Countries in May 1940, Roosevelt asked Congress for a supplemental appropriation of nearly a billion dollars, a production program of 50,000 aircraft a year, and a military air force of 50,000 aircraft (of which 36,500 would be Army). Accelerated programs followed in the Air Corps that repeatedly revised expansion goals, resulting in plans for 84 combat groups, 7,799 combat aircraft, and the annual addition to the force of 30,000 new pilots and 100,000 technical personnel. The accelerated expansion programs resulted in a force of 156 airfields and 152,125 personnel at the time of the creation of the Army Air Forces.
The German invasion of the Soviet Union, occurring only two days after the creation of the Army Air Forces, caused an immediate reassessment of U.S. defense strategy and policy. The need for an offensive strategy to defeat the Axis Powers required further enlargement and modernization of all the military services, including the new AAF. In addition, the invasion produced a new Lend lease partner in Russia, creating even greater demands on an already struggling American aircraft production.
