How the Air Force Turned the Tables on Nazi Germany's Luftwaffe
Between the world wars, the development of American pursuit aircraft was hobbled by budgetary restrictions that for many years slowed or obviated altogether the creation of new technologies or even methodical experimentation with new tactics. The U.S. Marine Corps did advance the use of the single-engine pursuit as a nascent close-support weapon to bolster the infantry, but the interests of various intra-Army constituencies prevented similar advances in what had come to be called the Army Air Corps.
The popular conception of the struggle in the air over northern Europe during World War II is of squadrons of sleek fighters racing over the German heartland to protect contrailed streams of lumbering bombers stretching beyond sight. This is as it was during the second half of America’s air war against Germany, but it was as far from the truth as it is possible to get at the start of that great aerial crusade. It took until late 1943—nearly two years after the United States entered World War II—before the United Kingdom-based Eighth Air Force mounted strategically significant bombing missions against targets in occupied northern Europe. The fault for this lay partly in the availability and slow development of the equipment, but it is also a fact that the two men at the top of the Eighth Air Force command structure stubbornly clung to old and discredited theories that stunted the effectiveness of the strategic-bombing effort and cost thousands of their countrymen their freedom or their lives.
