Liberty Ships
Liberty ships were the standardized cargo ships mass-produced in the United States during World War II, with 18 shipyards building 2,710 of them between 1941 and 1945, the largest number of ships ever built to a single design.
What happened and why it matters
Liberty ships showed how a standard design, prefabrication, and parallel production can scale capacity fast, ideas still used in modular warehouse construction and automation rollouts. The first, Patrick Henry, was launched on September 27, 1941, and took 244 days from keel laying to completion, while the Robert E. Peary was launched a record 4 days and 15 hours after its keel was laid, in a 1942 publicity effort. The yards averaged about three ships every two days. The ships carried much of the cargo that supplied Allied forces, and many stayed in merchant service for years after the war.
