SS Flying Enterprise was a 6,711 ton Type C1-B ship which sank off Cornwall in 1952. She was built in 1944 as SS Cape Kumukaki for the United States Maritime Commission for use in World War II. The ship was sold in 1947 and operated in scheduled service under the name Flying Enterprise. At the end of 1951, on a voyage from Hamburg to the USA with mixed cargo and a few passengers, she was crippled by storm damage and shifting cargo. Passengers and crew were evacuated. Three weeks of effort to save the ship having failed, she sank in January and some of the cargo was later salvaged.

Type C1 was a designation for cargo ships built for the United States Maritime Commission before and during World War II. Total production was 493 ships built from 1940 to 1945. 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.
