This is the longest air strike campaign in the world military history! Continuous bombing 1795 days, 4 million sorties were put into use, and the enemy troops were bombed continuously for 24 hours. A total of nearly 3 million tons of bombs were dropped, and 70,000 pilots spilled blood in the sky. This aerial bombing campaign was an air battle in which allied bombers bombed Germany. From 194 1 to 1945, this aerial bombing lasted for four years, the longest in the history of human bombing. More importantly, this bombing operation is the first time to launch a 24-hour all-weather bombing operation against enemy cities and other targets. Next, let's talk about how the Anglo-American Allied Forces bombed German cities 24 hours a day. 1942 On May 3 1 day, the Royal Air Force dispatched 1000 Lancaster bombers and launched a fierce air raid on the German city of Cologne. The air battle took place during the day because the bombers of the Royal Air Force lacked fighter escort. Under the interception of FW 190 fighter jets of the German Air Force, more than 200 British bombers were shot down by the Germans. The huge losses caused by bombing forced the British to think about a question-how can the British avoid the huge losses caused by bombing? And at this time, the number of fighters in the British Air Force is obviously insufficient. In addition to supporting the air force in the battlefield in North Africa, the British Air Force has been unable to provide more troops to escort bombers. In order to reduce the huge losses caused by air strikes against Germany, Britain decided to divide the work with the United States on air strikes against Germany: changing the tactics of the British Air Force in air strikes against German cities during the day. During the day, under the cover of fighter planes, American Army Air Force attacked German cities and other important military targets. The British Air Force dispatched at night, taking advantage of the shortage of night fighters in Germany, and directly attacked Germany. To tell the truth, this is not the right way. After all, the bombers of the US Army Air Force are supported by fighters, and their daytime bombing effect is much better than that of the British army without fighter escort bombing, and the loss is much smaller. So, from the second half of 1942, American bombing in the daytime and British bombing in the evening officially began. 1943, the allied air force launched three large-scale air raid campaigns in succession: Ruhr air raid campaign, Hamburg air raid campaign and Berlin air raid campaign. In these three air strikes, the allied forces achieved 24-hour high-intensity bombing. During the day, American bombers B 17, B24 and B25 took 1500 bombers as a large formation, and under the escort of 1000 fighters, they launched air strikes against Germany. The daytime bombing in the United States adopted the tactics of high-altitude bombing, and the bombing effect was very good. German local industry suffered a huge loss of 1943 production reduction by half. After the American bombing during the day, the British bombing came at night. British Lancaster bombers take 200-300 bombers as a formation, and the whole formation is commanded by a pilot. When the whole bomber formation flies over the target, the pilot drops the bomb first. Subsequently, more bombers dropped bombs behind the formation. After 24 hours of repeated bombing, American bombing during the day and British bombing at night, the enemy's target finally turned into ruins. Therefore, this 24-hour uninterrupted bombing made Germany pay a very heavy price, which also greatly accelerated the process of war victory, and the Allies also paid a heavy price for the death of 70,000 pilots. Of course, this 24-hour bombing is unprecedented in the history of human bombing.
