    The shattered, partially crushed remains of a U.S. World War II-era submarine were the focus of the last dive of NOAA Ocean Exploration’s 2021 ROV Shakedown expedition aboard NOAA Ship Okeanos Explorer on June 26. Using the hull-mounted multibeam sonar, the mapping team identified two interesting targets on the seabed in approximately 635 meters (2,000 feet ) of water. The targets were in the vicinity of the sinking coordinates provided by the U.S. Navy’s Naval History and Heritage Command (NHHC) of a veteran American submarine that had served in two navies between 1942 and 1968. Launched as USS Muskallunge (SS-262) in Groton, Connecticut, in 1942, the Gato-class submarine was one of nearly two hundred mass-produced American submarines, along with the Tench and Balao classes, that helped win World War II at sea.
