The Bomber Built Every 63 Minutes — America’s WWII Miracle

In the final months of World War II, American industry reached a level of production the world had never seen — and has never matched since. At the Ford-designed Willow Run factory in Michigan, B-24 Liberator bombers rolled off the assembly line with astonishing speed: 🚀 One complete bomber every 63 minutes. The factory covered 3.5 million square feet, employed more than 40,000 workers, and operated 24/7. It was the only plant on Earth capable of mass-producing heavy bombers like cars — using moving assembly lines, interchangeable parts, and streamlined workflows. By war’s end, the U.S. produced over 18,000 B-24s, making it the most manufactured heavy bomber in history. This unmatched industrial output helped the Allies gain total air superiority and ultimately win the war. The “one bomber per hour” pace remains one of the most extraordinary achievements in industrial history.l
