Military production during World War II includes the arms, ammunitions, natural resources, personnel and financing which were mobilized for the war. Military production, in this article, means everything produced by the belligerents from the occupation of Austria in early 1938 to the surrender and occupation of Japan in late 1945. The mobilization of funds, people, natural resources and matériel for the production and supply of military equipment and military forces during World War II was a critical component of the war effort. During the conflict, the Allies outpaced the Axis powers in most production categories. Access to the funding and industrial resources necessary to sustain the war effort was linked to their respective economic and political alliances. As formerly neutral powers (such as the United States) joined the escalating conflict, territory changed hands, combatants were defeated, the balance of power shifted in favour of the Allies (as did the means to sustain the military production required to win the war). ==Historical context== During the 1930s, political forces in Germany increased their financial investment in the military to develop the armed forces required to support near- and long-term political and territorial goals. Germany's economic, scientific, research and industrial capabilities were one of the most technically advanced in the world at the time and supported a rapidly growing, innovative military. However, access to (and control of) resources and production capacity required to entertain long-term goals (such as European control, German territorial expansion and the destruction of the USSR) were limited. Political demands necessitated the expansion of Germany's control of natural and human resources, industrial capacity and farmland beyond its borders. Germany's military production was tied to resources outside its area of control, a dynamic not found amongst the Allies. In 1938 the British Commonwealth was a global superpower, with political and economic control of a quarter of the world's population, industry and resources. From 1938 to mid-1942, the British coordinated the Allied effort in all global theatres. They fought the German, Italian, Japanese and Vichy armies, air forces and navies across Europe, Africa, Asia, the Middle East, India, the Mediterranean and in the Atlantic, Indian, Pacific and Arctic Oceans. British forces destroyed Italian armies in North and East Africa and occupied overseas colonies of occupied European nations. Following engagements with Axis forces, British Empire troops occupied Libya, Italian Somaliland, Eritrea, Ethiopia, Iran and Iraq. The Empire funded and delivered needed supplies by Arctic convoys to the USSR, and supported Free French forces to recapture French Equatorial Africa. Britain also established governments in exile in London to rally support in occupied Europe for the Allied effort. The British defeated, held back or slowed the Axis powers for three years while mobilizing their globally integrated economy and industrial infrastructure to build what became, by 1942, the most extensive military apparatus of the war. This allowed their later allies (such as the United States) to mobilise their economies and develop the military forces required to play a role in the war effort, and for the British to go on the offensive in its theatres of operation.〔History of the Second World War (104 volumes), Her Majesty's Stationery Office, London 1949 to 1993〕〔(【引用サイトリンク】title=rethinking history )〕 The entry of the United States into the war in late 1941 injected financial, human and industrial resources into Allied operations. Like the Commonwealth countries, the US produced more than its own military forces required and armed itself and its allies for the most industrialized war in history.〔Herman, Arthur. ''Freedom's Forge: How American Business Produced Victory in World War II,'' p. IX, Random House, New York, NY, 2012. ISBN 978-1-4000-6964-4.〕 At the beginning of the war, the British and French placed large orders for aircraft with American manufacturers and the US Congress approved plans to increase its air forces by 3,000 planes. In May 1940, Franklin D. Roosevelt called for the production of 185,000 aeroplanes, 120,000 tanks, 55,000 anti-aircraft guns and 18 million tons of merchant shipping in two years. Adolf Hitler was told by his advisors that this was American propaganda; in 1939, annual aircraft production for the US military was less than 3,000 planes. By the end of the war US factories had produced 300,000 planes,〔Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 7, Cypress, CA, 2013. ISBN 978-0-9897906-0-4.〕〔Wrynn, V. Dennis. ''Forge of Freedom: American Aircraft Production in World War II,'' pp. 4-5, Motorbooks International, Osceola, WI, 1995. ISBN 0-7603-0143-3.〕 and by 1944 had produced two-thirds of the Allied military equipment used in the war—bringing military forces into play in North and South America, the Caribbean, the Atlantic, Western Europe and the Pacific. The U.S. produced large quantities of military equipment into late 1945, including nuclear weapons, and became one of the strongest, most technically advanced military forces in the world. In addition to out-producing the Axis, the Allies produced technological innovations; through the Tizard Mission, British contributions included radar (instrumental in winning the Battle of Britain), sonar (improving their ability to sink U-boats), and the proximity fuze; the Americans led the Manhattan Project (which eliminated the need to invade Japan). The proximity fuze, for example, was five times as effective as contact or timed fuzes and was devastating in naval use against Japanese aircraft and so effective against German ground troops that General George S. Patton said it "won the Battle of the Bulge for us."〔Baldwin, Ralph B. ''The Deadly Fuze: Secret Weapon of World War II,'' pp. 4-6, 11, 50, 279, Presidio Press, San Rafael, California, 1980. ISBN 978-0-89141-087-4.〕 The human and social costs of the war on the population of the USSR were immense, with combat deaths alone in the millions. Recognising the importance of their population and industrial production to the war effort, the USSR evacuated the majority of its European territory—moving 2,500 factories, 17 million people and great quantities of resources to the east.〔Kumanev, G.A., "War and the evacuation of the USSR: 1941-1942", New Age, 2006〕 Out of German reach, the USSR produced equipment and forces critical to the Axis defeat in Europe. Over one million women served in the Soviet armed forces. The statistics below illustrate the extent to which the Allies outproduced the Axis. Production of machine tools tripled, and thousands of ships were built in shipyards which did not exist before the war.〔Sawyer, L. A. and Mitchell, W. H. ''The Liberty Ships: The History of the "Emergency" Type Cargo Ships Constructed in the United States During the Second World War,'' Second Edition, pp. vii, 1-8, Lloyd's of London Press Ltd., London, England, 1985. ISBN 1-85044-049-2.〕 According to William S. Knudsen, "We won because we smothered the enemy in an avalanche of production, the like of which he had never seen, nor dreamed possible."〔Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 5, 7, Cypress, CA, 2013. ISBN 978-0-9897906-0-4.〕 Access to resources and large, controlled international labour pools and the ability to build arms in relative peace were critical to the eventual victory of the Allies. According to Donald Douglas (founder of the Douglas Aircraft Company), "Here's proof that free men can out-produce slaves."〔Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 8, Cypress, California, 2013.
