context_page_description: The air warfare of World War II was a major component in all theaters of the war and, together with anti-aircraft warfare, consumed a large fraction of the industrial output of the major powers. Germany and Japan depended on air forces that were closely integrated with land and naval forces; the Axis powers downplayed the advantage of fleets of strategic bombers, and were late in appreciating the need to defend against Allied strategic bombing. By contrast, Britain and the United States took an approach that greatly emphasised strategic bombing, and tactical control of the battlefield by air, as well as adequate air defences. Both Britain and the U.S. built a substantially larger strategic forces of large, long-range bombers. Simultaneously, they built tactical air forces that could win air superiority over the battlefields, thereby giving vital assistance to ground troops. The U.S. and Royal Navy also built a powerful naval-air component based on aircraft carriers, as did the Japanese; these played the central role in the war at sea.
context_section_description: Air superiority or supremacy was a prerequisite to Operation Sea Lion, the planned German invasion of Britain. The Luftwaffe's primary task was intended to be the destruction of the Royal Air Force (RAF). The warplanes on both sides were comparable. Germany had more planes, but they used much of their fuel getting to Britain, and so had more limited time for combat.
  The Luftwaffe used 1,300 medium bombers guarded by 900 fighters; they made 1,500 sorties a day from bases in France, Belgium, and Norway. The Germans realized their Ju 87 Stukas and Heinkel He 111s were too vulnerable to modern British fighters. The RAF had 650 fighters, with more coming out of the factories every day. Three main fighter types were involved in the battle—the German Messerschmitt Bf 109E, and the British Hawker Hurricane and Supermarine Spitfire. The Hurricane accounted for most of the British kills throughout the battle because it made up the majority of the RAF fighter force—however, its kill-loss ratio was inferior to that of its counterpart the Spitfire. Of the three aircraft, the Hurricane was designed much earlier and was generally considered the least capable. Despite the high numbers of Hurricanes in the RAF at that time, the Spitfire became synonymous with the Battle of Britain and was somewhat of a symbol of resistance in the minds of the British public through the battle. The Bf 109E subtype's short combat radius of 330 km (205 mi) – due to limited fuel capacity as designed — prevented it from adequately "escorting" the Kampfgeschwader wings' medium bombers over England, limiting it to only some ten minutes of air combat over the UK before it had turn back to northern France for a safe return — this serious deficiency was not corrected until after the major air battles over England, through September 1940, had concluded.
  The Royal Air Force also had at its disposal a complex and integrated network of reporting stations and operations control rooms incorporating the new innovation of radar. Known as the Dowding system (after Hugh Dowding, the commander of RAF Fighter Command during the battle and the man who ordered its implementation), it was the first integrated air defence system in the world, and is often credited with giving the RAF the ability to effectively counter German raids without the need for regular patrols by fighter aircraft, increasing the efficiency with which the RAF fighter force could operate. As such, the Dowding system is also often credited with a significant role in the overall outcome of the battle, and comparisons with the air warfare that occurred over France in the spring and early summer of 1940, in which there was no such system and in which the allied air forces were comprehensively defeated, seem to support this.
  At first the Germans focused on RAF airfields and radar stations. However, when the RAF bomber forces (quite separate from the fighter forces) attacked Berlin, Hitler swore revenge and diverted the Luftwaffe to attacks on London. Using limited resources to attack civilians instead of airfields and radar proved a major mistake as the civilians being hit were far less critical than the airfields and radar stations that were now ignored. London was not a factory city and British aircraft production was not impeded; indeed it went up. The last German daylight raid came on September 30; the Luftwaffe realized it was taking unacceptable losses and broke off the attack; occasional blitz raids hit London and other cities from time. In all some 43,000 civilians were killed. The Luftwaffe lost 1,411 planes shot down of a grand total of 2,069 which were written off, the British lost about the same number, but could repair 289 of them. The British additionally lost 497 aircraft of Bomber and RAF Coastal Command shot down during that same period and hundreds of planes destroyed on the ground, lost by accidents or also written off. The successful British defense resulted from a better system that provided more concentration, better utilization of radar, and better ground control.
