Another German WW2 submarine located off Norway
The "U-486" was torpedoed and broken in two by a British submarine in April 1945 shortly after leaving the western Norwegian town of Bergen. There was no survivors.
Her remains were positively identified in March of 2013 after they were found during oil exploration operations off the coast of Norway, not far from the remains of U-864.
The oil company Statoil was working on a pipeline off the coast of Norway when they came across the remains of the sunken submarine.
The boat began training on March 22 with the 5th U-boat Flotilla but moved on to the 11th flotilla for operations. She was one of nine Type VIIs that the Kriegsmarine fitted with an experimental synthetic rubber skin of anechoic tiles known as Alberich, which had been designed to counter the Allies' asdic/sonar devices.
Arild Maroey Hansen of the Bergen Maritime Museum told Norwegian radio station NRK, that the potential presence of fuel oil and unexploded torpedoes on the recently found submarine could pose a similar problem, while also raising the possibility of other sunken vessels that have yet to be found in nearby waters.
The submarine had a special coating on the hull. It was a synthetic rubber coating designed to significantly reduce its radar signal.
