The Emergency Fleet Corporation (EFC) was established by the United States Shipping Board, sometimes referred to as the War Shipping Board, on 16 April 1917[1] pursuant to the Shipping Act (39 Stat. 729) to acquire, maintain, and operate merchant ships to meet national defense, foreign and domestic commerce during World War I.
The Shipping Board had been established while the United States was at peace, with the intent to restore the nation's Merchant Marine. That changed with war. In the words of Edward N. Hurley, Chairman of the Board:
When the United States declared war against Germany the whole purpose and policy of the Shipping Board and the Fleet Corporation suffered a radical change overnight. From a body established to restore the American Merchant Marine to its old glory, the Shipping Board was transformed into a military agency to bridge the ocean with ships and to maintain the line of communication between America and Europe. Conceived as an instrumentality of peace, the Board became an instrumentality of war. Unlike other military agencies—the Army and Navy—it began with nothing—no ships, no officers, no crews, no organizations.[1]
Ten days after the declaration of war the Emergency Fleet Corporation was established in response to those wartime requirements.
The EFC was renamed the U.S. Shipping Board Merchant Fleet Corporation in February 1927, then abolished entirely in October 1936. Its functions were transferred to the United States Maritime Commission.[2]
