This videograb shows the wreck of a Nazi cruiser found 13 naval miles from Kristiansand, Norway
Oslo, Norway: A Nazi cruiser torpedoed and sunk off the coast of Norway in 1940 has been found by chance at a depth of 490 metres (535 yards) during a subsea power cable inspection, the finders said on Thursday.
"Sometimes, we discover historical remains. But I've never found anything as exciting as this one," Ole Petter Hobberstad, a chief engineer at Norway's power network operator Statnett, told AFP.
The German navy ship Karlsruhe, measuring 174 metres (571 feet), took part in the invasion of Norway during World War II.
After troops had disembarked on April 9, 1940 it was hit by Norwegian artillery then torpedoed by a British submarine. Badly damaged, it was finally ordered sunk by the German captain off the port of Kristiansand, at Norway's southern tip.
Three years ago, Statnett's sonars detected an unidentified wreck close to a high-tension cable between Norway and Denmark, but the company's engineers did not have time to investigate further, Statnett said.
But on June 30, after a storm in the area, a team was sent out to inspect the wreck with a remotely-operated vehicle (ROV).
About 15 metres from the cable, the ROV "showed a huge shipwreck that was torpedoed. But it was not until the cannons -- and Nazi symbol -- became visible on the screen that Ole Petter Hobberstad and the crew understood it was from the war," Statnett said in a statement.
Norway's Maritime Museum later confirmed that there was no doubt: the wreck was indeed that of the Karlsruhe, which had never been found.
The ship is located 13 nautical miles off of Kristiansand. It lies upright on the seabed, a rare sight for warships with a high centre of gravity which normally list over, according to experts.
Built in Kiel in northern Germany, the cruiser was launched in 1927.
