In 1941, as German U-boats devastated Allied convoys in the Atlantic, the United States faced a crisis: how to build thousands of cargo ships fast enough to keep Britain alive. The Liberty Ship program was supposed to be the answer — but traditional shipbuilding methods were far too slow.

Then, a young engineer named Donald W. Bailey proposed a radical idea that would change everything: replace slow, labor-intensive riveting with welding, and build ships from prefabricated steel sections assembled like an industrial puzzle. His simple welding innovation would cut construction times from eight months to mere weeks, transforming shipyards into massive wartime assembly lines.

Backed by industrial visionary Henry J. Kaiser, Bailey’s “simple trick” revolutionized shipbuilding, saving the Liberty Ship program and turning the tide of the Battle of the Atlantic. From Richmond’s foggy shipyards to the roaring docks of Portland and Baltimore, welding replaced riveting, and a new industrial miracle was born — one that even Germany’s U-boat commanders couldn’t outpace.

This documentary explores how Bailey’s welding breakthrough became one of World War II’s greatest engineering revolutions, how it mobilized thousands of new workers — including women welders — and how it symbolized the unstoppable power of American industry under fire.

Watch how one man’s idea helped forge the fleet that defeated the U-boats, and discover the untold story behind the phrase: “You can’t sink them fast enough.”
