Victory ship Class of US cargo ship, 1940s

The Victory ship was a class of cargo ship produced in large numbers by American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines, giving higher speed to allow participation in high-speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built in between 1944 and 1946.
