U.S. Maritime Commission type EC2-S-C1 “Liberty Ship”

The driving force behind the Liberty ship design was speed of construction. The U.S. Maritime Commission initially designed and contracted its standardized “C” cargo ships at a relatively leisurely pace, but by the beginning of 1941...

The final ships designed by the U.S. Maritime Commission, the Mariner-class, did not go into production until after the U.S. government had reorganized the agency as the Maritime Administration under the Department of Commerce....

U.S. Maritime Commission Post-World War II

After World War II, the surplus of cargo ships produced by the Emergency Shipbuilding Program meant that the U.S. Maritime Commission had several years to develop a successor to the Victory ship and Long Range Shipbuilding Program-era designs.  The final two vessels designed and ordered by...

Vessels for the U.S. Navy

As a part of the Emergency Shipbuilding Program, the U.S. Maritime Commission, in addition to the construction of cargo ships and tankers, also built many commissioned U.S. Navy vessels. Between 1939 and 1945, the commission oversaw the delivery of 682 “military” type vessels.

C1-B Type

The C1 type was the smallest and slowest of the three standard cargo designs in the U.S. Maritime Commission’s Long Range Shipbuilding Program. Intended as an economical choice for tramp services and coastwise trade where speed was not essential, these vessels had five holds and a capacity of 6,...

The Long Range Shipbuilding Program

In order to meet its ambitious 500-ship goal, the U.S. Maritime Commission turned to a concept that had been used with some success by its predecessor during World War I; design standardization. Traditionally, shipping lines designed their vessels to service specific routes; this made each ship...
