It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet.
The War Shipping Administration (WSA) was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the United States needed for fighting the war.
