The USS Razorback (SS-394) is a Balao-class submarine that was launched in 1944. It served in the United States Navy during World War II and the Cold War, primarily conducting reconnaissance and training missions. The submarine was decommissioned in 1970 and later became a museum ship in Little Rock, Arkansas. The Razorback is notable for its long service history and is one of the few remaining submarines from its era. It is now part of the Arkansas Inland Maritime Museum, where visitors can explore its interior and learn about submarine operations and naval history.
