HMS Lawford, the Royal Naval frigate attacked during the Normandy landings in 1944.
Imperial War Museum A21817

During the invasion of France on D-Day in 1944, the HMS Lawford was hit by enemy fire and sank. Thirty-seven of her crew died. The Navy's explanation that the ship was downed by a torpedo had never been fully accepted. The Wreck Detectives have gone to Normandy, taking two survivors, to try and solve this personal mystery.

The survivors' accounts tell of an explosion on the ship before it sank. The explosion could have been caused by a torpedo or a guided missile. Each weapon leaves distinctively different impact marks on wreckage, but no signs of impact were found. High-tech survey equipment revealed a new piece of wreckage that provided the missing piece of the puzzle. The metal structure was bent outwards, showing the explosion came from inside the ship. This means it was a guided missile, that enters the ships and then detonates, that sank the HMS Lawford.
