Fortunately for the U.S., President Franklin D. Roosevelt realized the dominant role played by Hitler's Luftwaffe in European international relations, and on Jan. 12, 1939, he delivered a special message to Congress calling for strengthening of the Air Corps. Congress then authorized $300 million for 5,500 new airplanes. This was a "shot in the arm" for the U.S. aircraft industry which began to expand immediately. With another war believed imminent, many nations began placing large orders for American airplanes, a further boost for U.S. manufacturers. With this increase in activity came a corresponding increase in research, which though it had not been ignored in the 1930s, had been greatly limited by lack of funds.
