The USS C-4 was a C-class submarine of the United States Navy built during World War I. Commissioned in 1917, it was known for its unique design featuring a single propeller and a distinctive "X" configuration of its four engines. The submarine had a brief service history, participating in training exercises and patrolling the East Coast of the United States during the war. Following the war, the USS C-4 was decommissioned in 1922 and laid up in reserve. In 1931, it was converted into a cargo submarine and redesignated as USS Argonaut, serving in this capacity until 1945. During World War II, the USS Argonaut played a significant role in transporting critical supplies and personnel to American forces in the Pacific Theater. The submarine was eventually decommissioned in 1945 and sold for scrap in 1946. The USS C-4/USS Argonaut's unique design and dual role as both a military submarine and a cargo vessel make it a notable and historically significant ship in the annals of U.S. naval history.
