Photos show the recently discovered wreck of a World War II-era submarine more than 80 years after a German sub sank it

• Researchers discovered the wreck of a World War II-era submarine off the coast of Norway this year. 
• The HMS Thistle was a British sub that sank after being hit by a German vessel in 1940.
• Researchers initially thought the wreck could be that of the HMS Oxley instead.

A crew of Norwegian maritime researchers said they stumbled upon the long-lost wreck of a World War II-era British submarine that was torpedoed by a German submarine in 1940 just seven months after the war began.
