Liberty ship program (1941–1945)
Facing a U-boat threat to Atlantic supply lines, the U.S. launched the Emergency Shipbuilding Program. Henry Kaiser's yards pioneered welding and prefabrication, cutting construction from months to weeks and producing nearly 2,700 Liberty ships.
America outbuilt its rivals, and the merchant fleet swelled to support the war effort.
Those yards sustained U.S. maritime dominance for decades, then closed and atrophied after the war.
Mavrookas cites that World War II-era output, thousands of vessels a year, as the benchmark Port Alpha aims to recapture with modular, high-throughput construction.
