Liberty Ships were a class of US cargo ships built under the Emergency Ship Building Program. These were mass produced on an epic scale and were a symbol of US economic power. The class was developed to satisfy requirements for British transport. About 2,700 were built in 18 US shipyards. This was the largest number for a particular class during WWII. Another very notable fact is that many female workers were involved in production of these ships.
