Aircraft, Production of

Key aspect of World War II industrial production that tipped the scales of the air war decisively away from the Axis powers in favor of the Allies. Although Germany and Japan had entered the war with initial advantages of aircraft and other war matériel because they had begun military production much earlier than the Allies, the combined industrial potential of the Allies far exceeded that of the Axis nations. Even though Axis aircraft production increased during the course of the war, it paled in comparison to that of the Allies, especially the United States. To the extent that World War II was a total war that depended on industrial output, the Allied advantage in manpower and industry ultimately proved decisive, and aircraft production is a key indicator of that advantage.

Axis Powers

Although Germany had entered the war in September 1939 as the world's leading air power, with 4,840 frontline aircraft and an aircraft industry producing 1,000 airplanes a month, the Luftwaffe's arsenal had serious defects. For one, Germany had never developed a satisfactory long-range bomber, in part because the German military's focus on blitzkrieg (lightning war) emphasized production of medium-range bombers and ground-attack aircraft, which had proven so successful in the Spanish Civil War. Germany's defeat in the Battle of Britain revealed the flaw of this policy from a strategic standpoint, as aircraft such as Heinkel He-111, Dornier Do-17, and Junkers Ju-87 proved ineffective against a technologically well-equipped enemy force. Likewise, Germany's lack of long-range bombers prevented it from conducting long-range air operations at sea or striking Soviet manufacturing centers relocated deep within the Soviet Union. Despite the damage inflicted by the Allied air campaign, the German armaments industry, ably led by Fritz Todt and Albert Speer, not only managed to increase production from 8,295 aircraft in 1939 to 39,807 in 1944 but also introduced the world's first jet fighter, the Messerschmitt Me-262, in the second half of 1944. These successes, however, proved to be too little and too late to make a difference, and the Allies had air supremacy in the last two years of the war.

As with Germany, Japan entered the war with a powerful air arm, which included some 2,900 combat-ready aircraft on 7 December 1941. Yet, Japan's attack on Pearl Harbor was in part a desperate gamble designed to cripple the United States to purchase time for Japan to build a defensive perimeter before U.S. industrial might reached heights that Japan knew it could never equal. Indeed, Japanese industry produced just 5,088 aircraft in 1941, compared with 26,277 for the United States. Failure to destroy the U.S. carriers in the surprise attack on Pearl Harbor ranks as a clear strategic mistake for Japan. Once it lost the Battle of Midway in early June 1942, Japan was forced into a defensive war in which it could not compete with the American war machine. Despite Allied attacks that crippled its shipping industry and weakened its industrial infrastructure, Japan still managed to produce 28,180 aircraft in 1944, a testament to the perseverance of its workers on the home front. That the United States produced 96,318 aircraft during the same year is a testament to the futility of Japan's challenge to American industrial might.

Although Benito Mussolini had built a powerful Italian air force in the late 1920s and early 1930s, by the beginning of World War II in September 1939, Italy's air force had become largely obsolete. This decline was in part a reflection of Italy's weak economy. When Italy joined the war on 10 June 1940, barely half of its 3,296 aircraft were of combat quality. While assistance from Germany (particularly in supplying aircraft engines) allowed the Italian aircraft industry to make modest increases from 2,142 aircraft produced in 1940 to 3,503 aircraft in 1941, Italy's weak industrial sector could not withstand the impact of the Allied bombing campaign, and production dropped to 2,818 aircraft in 1942 and just 967 aircraft by the time Italy surrendered in September 1943.

Allied Powers

Although Germany enjoyed a great lead in the number of its combat-ready aircraft at the start of the war, Great Britain had an advantage in that its industry was in the process of introducing aircraft (such as the Hawker Hurricane and Supermarine Spitfire) more technologically advanced than their German counterparts. This qualitative advantage would prove critical to defeating Germany in the Battle of Britain. Secure from the threat of German invasion, British industry succeeded not only in increasing productive capacity with each passing year of the war but also in introducing aircraft such as the Handley Page Halifax and Avro Lancaster that played a critical role in the Allied bombing campaign against Germany. Great Britain's highest annual production total reached 26,461 aircraft in 1944, compared with 39,807 aircraft for Germany that year. Nevertheless, Great Britain's overall production of 131,550 aircraft during the war exceeded that of Germany, which produced 119,331 aircraft.

The Soviet Union possessed large numbers of aircraft at the outbreak of the war, but most of these were inferior to their German counterparts. Making matters worse, when Germany launched its invasion of the Soviet Union on 22 June 1941, it destroyed 1,200 Soviet aircraft in the first nine hours of the attack. The Soviet Union managed not only to sustain this loss but to recover, because of its monumental efforts to transfer industries eastward beyond the reach of the German army and air force. In the first three months after the German invasion, the Soviet Union relocated 1,523 factories. The primary production line for the Yakovlev Yak-1, for example, was moved more than 1,000 miles and returned to production in less than six weeks. The success of these efforts allowed the Soviet Union to exceed German production for each year of the war, including 1941, for a total of 159,261 Soviet aircraft compared with 119,331 German aircraft.

In 1939, the U.S. economy was still suffering from the Great Depression, with 8.9 million registered unemployed workers. However, the success of the German blitzkrieg against western Europe in 1940 spurred the American war machine into action. The Burke-Wadsworth Act of 16 September 1940 introduced peacetime conscription for the first time in American history, and massive military spending got the American economy working again. Unlike Germany and Japan, the United States not only had a large population base and natural resources that could be mobilized for production but also enjoyed an industrial infrastructure far removed from its enemies. By 1944, a total of 18.7 million Americans, approximately 50 percent of whom were women, had entered the American workforce. Of all of their industrial achievements, none was more spectacular than aircraft production. From just 5,856 aircraft produced in 1939, the United States would reach the staggering total of 96,318 produced in 1944—almost one-third more than that produced by Germany and Japan combined for that year. For the war years as a whole, the United States would produce 324,750 aircraft, compared with a total of 206,773 for Germany, Japan, and Italy. The U.S. output, combined with the output of the British and the Soviet Union, gave the Allies an advantage greater than three to one, with 615,561 aircraft. With such an advantage, it is little wonder that the Allies won the war in the air.
