Video: Marine robots provide sonar images of the sunken D-Day rehearsal ships


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. A tragic but largely unknown military operation, Exercise Tiger was a D-Day rehearsal for the invasion of Normandy's Utah Beach. The exercise took place off the southern English coast and resulted in the loss of nearly 1,000 American servicemen - more than the number of deaths at the actual invasion of Utah Beach.
