Vad gjorde Losharik utanför Norges kust

New York Times:

There could hardly have been a more terrifying place to fight a fire than in the belly of the Losharik, a mysterious deep-diving Russian submarine.
Something, it appears, had gone terribly wrong in the battery compartment as the sub made its way through Russian waters 250 miles north of the Arctic Circle on the First of July.

A fire on any submarine may be a mariner’s worst nightmare, but a fire on the Losharik was a threat of another order altogether. The vessel is able to dive far deeper than almost any other sub, but the feats of engineering that allow it do so may have helped seal the fate of the 14 sailors killed in the disaster.

The only thing more mysterious than what exactly went wrong that day is what the sub was doing in a thousand feet of water just 60 nautical miles east of Norway in the first place.
