True

Explanation:

A year later, after Pearl Harbor, the United States was at war. But in the meantime, another giant, state-of-the-art factory had been built near Detroit: the Detroit Tank Arsenal. Because Detroit already had a large automobile industry with factories ready to produce vehicles using relatively-new assembly-line techniques, it was well-suited to producing war machines. At the start of America's war, writes the Detroit Historical Society, as many as 350,000 workers moved to Detroit to work in factories producing war equipment.
