Answer:
The main purpose of the War Industry Board was to make sure that the nation’s industries had what they needed to win the war.
Explanation:
The War Industry Board was an American government agency existing from July 28, 1917 to November 30, 1918, whose task was to organize and coordinate the work of the American industries to win World War I.
Before World War I, the US government did not intervene in the functioning of the American economy. The need for a well-organized effort to win the war led to a change in policy and a top-down switch of industrial production to the needs of waging war, including the nationalization of enterprises and entire industries. Even before the war began preparations were started, launching a weapons program and a procurement program.
