The USS Harder sank Japanese ships in audacious missions during the war.

The wreckage of a US Navy submarine that sank the most Japanese warships during World War Two has been found in the South China Sea, some 80 years after it was sunk by enemy forces.

The USS Harder was found 3,000ft (914m) below water off the Philippines’ northern island of Luzon.

The Harder was sunk in battle on 29 August 1944, along with its crew of 79 men.
