Type C1 ship

Type C1 was a designation for small cargo ships built for the U.S. Maritime Commission before and during World War II. The first C1 types were the smallest of the three original Maritime Commission designs, meant for shorter routes where high speed and capacity were less important. Only a handful were delivered prior to Pearl Harbor. But many C1-A and C1-B ships were already in the works and were delivered during 1942. Many were converted to military purposes including troop-transports during the war.

The Type C1-M ship was a separate design, for a significantly smaller and shallower draft vessel. This design evolved as an answer for the projected needs for military transport and supply of the Pacific Ocean theater of World War II.

Note any Type C1 ship in the control of the British Ministry of War Transport took an Empire name even if being built as another name e.g. Cape Turner.

The United States Maritime Commission (MARCOM) was an Independent agencies of the United States government that was created by the Merchant Marine Act of 1936, passed by Congress on 29 June 1936 and replaced the U.S. Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to supplement and replace the World War I vintage vessels, including Hog Islander ships, that comprised the bulk of the U.S. Merchant Marine.

From 1939 through the end of World War II, MARCOM funded and administered the largest and most successful merchant shipbuilding effort in world history, producing thousands of ships, including Liberty ships, Victory ships, and others, notably type C1 ships, type C2 ships, type C3 ships, type C4 ships, T2 tankers, Landing Ship Tank (LST)s and patrol frigates. By the end of the war, U.S. shipyards working under MARCOM contracts had built a total of 5,777 oceangoing merchant and naval ships.
