The USS Seginus was a cargo ship belonging to the Crater Class that was commissioned by the U.S. Navy to be used during World War II. The ship was built under a MARCOM contract as the Liberty Ship SS Harry Toulmin in January 1944. Once it was acquired by the Navy, the vessel carried cargo and foodstuffs to Pearl Harbor and then proceeded to shuttle cargo between the West Coast and Hawaii. Once the war was over, the ship was decommissioned and sold into private ownership for commercial use. It remained in service until 1967 when it was scrapped in Shanghai.
