USS Cavalla was called “The Luckiest Ship in the Submarine Service” because of her outstanding performance during her short time in service before the end of World War II. She logged 90,000 miles, made 570 dives, and sank 34,180 tons of Japanese shipping. Her greatest sinking, during six war patrols, was the aircraft carrier Shokaku that had participated in the attack on Pearl Harbor. She was present in Tokyo Bay in September 1945 for the surrender signing aboard Missouri.
Cavalla was decommissioned in 1946 and returned to service in 1951 to be converted to a hunter-killer submarine (SSK). She was assigned the experimental designation AGSS in 1963. She was transferred to the U.S. Submarine Veterans of World War II in early 1971, and delivered to her permanent berth later that year. She serves as a memorial to submariners lost in World War II.
USS Cavalla is a National Historic Landmark.
