WWII: ratio of GDP of the Soviet Union and Germany 1938-1945

The Second World War's Eastern Front, the largest theater of war in history, was largely dominated by the conflict between Germany and the Soviet Union. The two countries had agreed upon an unexpected peace pact in 1939, with the joint invasion and partition of Poland, but this peace was broken in June 1941 when Germany invaded the Soviet Union during Operation Barbarossa. Germany's economic and technological superiority, alongside its Blitzkrieg military strategy, allowed it to gain the upper hand in the early stages of the conflict. Within six months the Germans had pushed the frontlines back to Moscow, and almost 40 percent of the Soviet population now lived in occupied territory. German gains at the expense of the Soviets was reflected in the changing balance of their economies - Germany's GDP grew each year until 1944, whereas the Soviet GDP fell by one third between 1940 and 1942.
