Military production during World War II
Military production during World War II was the arms, ammunition, personnel and financing which were produced or mobilized by the belligerents of the war 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 material 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. 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, supporting a rapidly growing, innovative military. However, access to (and control of) the 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 Britain was a global superpower, with political and economic control of a quarter of the world's population, industry and resources, in addition to its close allies in the independent Dominion nations (such as Canada and South Africa). 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 held back or slowed the Axis powers for three years while mobilising 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. The entry of the United States into the war in late 1941 injected financial , human and industrial resources into Allied operations. The US produced more than its own military forces required and armed itself and its allies for the most industrialized war in history. 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, 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 vast quantities of military equipment into late 1945, including nuclear weapons, and became the strongest, most technologically 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." 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. 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. 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." 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. Donald Douglas (founder of the Douglas Aircraft Company) declared, "Here's proof that free men can out-produce slaves." Production summaries 1939–1945. Economy.

Gross domestic product (GDP) provides insight into the relative strength of the belligerents in the run up to, and during the conflict. Romanian, Hungarian, Bulgarian and Albanian GDP calculated by multiplying the GDP per capita of the four countries in 1938 ($1,242 for Romania, $2,655 for Hungary, $1,595 for Bulgaria and over $900 for Albania) by their estimated populations in 1938: 19,750,000 for Romania, 9,082,400 for Hungary, 6,380,000 for Bulgaria and 1,040,400 for Albania. Table notes United States World War II GDP (compared to other countries). Price  of war. Many concerns and political influence come from the price of war. While GDP can easily increase Federal expenditures, it also can influence political elections and government decision making. No matter how much percentages of GDP increase or decrease we need higher amounts of GDP in order to pay for more investments, one of those investments being more wars. To pay for these wars, taxes are held at a very high rate. For example, by the end of World War II tax rates went from 1.5% to 15%. Along with tax percentages reaching high amounts, spending on non-defense  programs were cut in half during the period of World War II. Tax cuts allow one to see GDP in effect for the average American. Still, almost ten years after World War II, in 1950 and 1951 congress raised taxes close to 4% in order to pay for the Korean War. After the Korean War, in 1968 taxes again were raised 10% to pay for the Vietnam War. This caused GDP to raise 1%. Although research can support positive relationship between production and jobs with GDP, research can also show the negative relationship with tax increases and GDP. US Wartime  Production. Prior to the Second World War, the United States was cautious with regard to its manufacturing capabilities as the country was still recovering from the Great Depression. However, during the war, Franklin Roosevelt set ambitious production goals to fulfill. The early 1940s were set to have 60,000 aircraft increasing to 125,000 in 1943. In addition, targets for the production of 120,000 tanks and 55,000 aircraft were set during the same time period. The Ford Motor Company in Michigan built one motor car (comprising 15,000 parts) on the assembly lines every 69 seconds. Ford's production contributed to America's  total production of vehicles totalling three million in 1941. American production numbers caused the US employed workforce to increase massively. America's yearly production exceeded Japan's production building more planes in 1944 than Japan built in all the war years combined. As a result, half of the world's war production came from America. The government paid for this production using techniques of selling war bonds to financial institutions, rationing household items and creating more tax revenues. One part of the US wartime manufacturing boom can be ascribed to Alcoa's second major reduction plant in Mobile, Alabama starting  in 1937. At first serving mainly the Japanese market, the plant prepared thousands of tons of aluminum for the production of aeroplanes during the war. The United States quickly adjusted to the levels of production required to equip its military with the millions of war products used during World War II. Personnel – Allied – Britain, dominions and possessions. Including all non-British subjects in British services. Note: Personnel – Axis – German Reich. This includes all German and non-German subjects serving within German Reich forces. Note: Aircraft – Allied – British Empire. Within the UK, initially aircraft production was very vulnerable to enemy bombing . To expand and diversify the production base the British set up "Shadow factories". These brought other manufacturing companies – such as vehicle manufacturers – into aircraft production, or aircraft parts production. These inexperienced companies were set up in groups under the guidance or control of the aircraft manufacturers. New factory buildings were provided with government money. Aircraft – Allies – France, Poland and minor powers. Production numbers until the time of the German occupation of the respective country. Some types listed were in production before the war, those listed were still in production at the time of or after the Munich crisis. Aircraft - Axis  - All.
