A welder works on cowls for Liberty Ships in California, 1942. At the peak of the Liberty ship production, shipyards could deliver a completed vessel in less than a week.

Peary, built by the Kaiser Permanente Metals Corporation’s yard in Richmond, California, launched just 4 days, 15 hours, and 30 minutes after the keel was laid. https://navalhistoria.com/the-liberty-ships-of-world-war-ii-an-icon-of-american-industrial-might/
