You may remember a few months back when the Swedish coastal artillery and naval forces went ape shit on a possible non-NATO (read= Russki) midget sub in their territorial waters– and reportedly dropped a good number of ASW weapons on active contacts. Well, it seems like they have found a 20m (66 foot) long 3m (10 foot) abeam submarine in their waters with Cyrillic letters on its hull.
As reported by The Express, a Swedish newspaper, the submarine is just under two miles off the coast of Sweden, although Ocean X, the team that discovered it, are not disclosing its exact location.
It was discovered last week, and the Swedish armed forces confirmed to the paper that the images of the craft are currently being analyzed.
HI Sutton over at Covert Shores thinks it could be an unknown Russian midget, possibly a variant of the Piranha-M.
While Per Andersson, a retired lieutenant colonel in the Swedish Coastal Artillery, says he is “sure” it is a much older submarine, and says he has been in touch with former military colleagues who agree with him.

Electric Boat built the Fulton (renamed the Som/Catfish) in the U.S. then disassembled her in 1904 and shipped the craft to Russia
They feel it could be the old Tsarist Navy’s Som, the 66-foot long, 11-foot abeam craft built originally as the private submarine Fulton by the Electric Boat Company in 1901 and sold to the Tsar during the Russo-Japanese war.
The humble Som was lost in the Baltic in 1916 but her grave has been lost to history.
Either way, its going to be interesting to find out just which one it is.
UPDATE:
It looks like its the Som.
