The great endeavor

“The wartime expansion of the U.S. Navy was an extraordinary achievement, which should never be taken for granted. Between 1941 and 1945, its tonnage swelled from three million to almost thirty. Of the service’s total war expenditure of $100 billion, more than a third went to ship construction. . . . Mare Island Navy Yard expanded from 6,000 employees in 1939 to 40,000 in 1944, Boston Yard from 8,700 in June 1940 to 50,000 three years later. . . . By 1944 more than a million workers were building and repairing ships, 55 percent of them on the Atlantic coast, 27 percent on the Pacific, while a further two million served supporting industries. Most were working forty-eight-hour weeks on multiple shifts. . . . Many smaller vessels, submarines and escorts, were built in sections at plants as far inland as Denver, then transported to the coasts for completion. Thousands of landing ships were constructed on the Great Lakes and sailed to the sea.” – Max Hastings, Retribution
