Development of the American economy during World War II
On March 11, 1941, the President of the United States signed the Lend-Lease Act. The name was not chosen at random: "The term loan and lease has been used to divert attention from the fact that the US government is financing weapons supplied to Britain and its allies."

On the example of aviation and the industry associated with it, I will approach the basic factors of the development of American economic development towards post-war dominance.
