Mission commemorates 70th anniversary of World War II Tragedy. A mission off the coast of South Devon, England has surveyed two U.S. Landing Ship Tanks (LSTs) that were torpedoed and sunk during the D-Day rehearsal Exercise Tiger on April 28, 1944. Using state-of-the-art autonomous underwater vehicle (AUV) technology to collect data from the wreckage site, the mission has produced the first high-definition sonar images of this World War II tragedy. This was the first time in history that an AUV had surveyed the area. The mission, which was executed by Hydroid, Inc., a subsidiary of Kongsberg Maritime and the leading manufacturer of AUVs, with additional data provided by the Royal Navy's Maritime Autonomous System Trials Team (MASTT), commemorates the 70th anniversary of Exercise Tiger.
