As did most of big industry before the war to not only Germany but to the Soviet Union also. Without all the help U.S. industry gave those two countries neither would have had the capacity to make war on the scale they did.
Neither country was ever able to produce the amount of military war machinery that the U.S. did. We supplied Russia with complete factories so they could produce their own stuff. We sent civilian engineers, architects, etc. there to help them get the buildings up and running. We also sent them a vast amount of train engines and railroad cars. When Germany invaded Russia, Stalin had the people dismantle the factories so the Germans couldn't get their hands on them, and moved them by train farther into the interior, to be reconstructed in order to continue production.
