Wesley W. Stout's Bullets by the Billion is an extraordinary behind-the-scenes account of one of the greatest feats of American industrial production during World War II—the manufacture of small arms ammunition on a scale never before attempted. Commissioned by the Chrysler Corporation, the book focuses on the history and operations of the Dodge-Chicago Ordnance Plant, which was built almost overnight and eventually produced more than eight billion bullets for the Allied war effort. With journalistic precision and narrative flair, Stout describes the engineering marvels, logistical challenges, labor force dynamics, and patriotic spirit that animated this massive undertaking. He celebrates not just the machines and output, but the people—men and women, engineers and inspectors, assembly workers and janitors—whose dedication made it possible. Interwoven throughout the story is a larger message about American innovation, adaptability, and resolve under pressure. The book is richly illustrated and patriotic in tone, reflecting both wartime urgency and postwar pride. Today, Bullets by the Billion serves as a case study in rapid-scale manufacturing, workforce mobilization, and industrial wartime history. It is essential reading for military historians, industrial engineers, and anyone interested in the domestic front of the Second World War.
