Swedish officials say they are investigating a mysterious submarine that apparently ran aground in territorial waters two miles off of Sweden’s coastline.
Sea explorers with Ocean X spotted the roughly 65-foot submersible at an undisclosed location last week, prompting speculation about its origins. Ocean X explorer Dennis Åsberg told Swedish newspaper Expressen that the submarine appeared to have Russian cyrillic characters on its hull and no signs of physical damage.
The absence of a distress signal led one defense expert to speculate that the submarine may have run aground recently while on a confidential mission, while other experts suspect that the craft dates back to WWI.
The Ocean X team said it had partnered with Swedish officials to conduct further analysis into the submarine’s origins.
The investigation comes one year after Swedish intelligence agents detected a foreign submarine, transmitting Russian distress signals, east of Stockholm.
