Submarine Mystery Question of the Week

Background

On October 23rd, Molten Eagle provided our analysis of Sweden's recent Hunt for Little Read October: Just a Navy Training Drill?

We provided the following facts:

• July 1, 2010  STOCKHOLM - Sweden ended 109 years of obligatory military service, setting the Scandinavian nation on the way to becoming a fully professional army.
• February 8, 2011 - StrategyPage - Sweden Runs Out Of Soldiers by James Dunnigan                ... Many of those officers and NCOs are simply leaving the military, or planning to. So there is some anxiety about what shape the Swedish military will be in by 2014, although at this point it appears it will be smaller than planned. 

and, the following alleged facts:   

• Sweden had begun a search after a distress signal in Russian was detected on an emergency frequency on Thursday evening. 
• Encrypted radio traffic from a point in the Stockholm archipelago and Kaliningrad were also later picked up.  

We quickly concluded: 
 It is more likely, in our experience, that a much needed Swedish Military training excercise, a public relations recruiting effort, or a combination of both, have been conducted with renewed world attention.   

But now, You can judge the latest facts...

•  October 28, 2014 -  The Local - Sweden could see return to military service                    A return to compulsory military service is being considered by Sweden's new Defence Minister Peter Hultqvist, four years after the policy was scrapped.
  

•  November 14, 2014 - BBC News - Sweden releases sonar image confirming 'foreign submarine'             

"Sweden has released a sonar image it says is proof that a foreign submarine entered its waters in October.  The grainy image shows underwater tracks allegedly left by the vessel."

•  

OPPOSITE from the arrow's direction, one plainly sees individual cross-stitches.
 
Well, do you agree, or not?  If not, please be good enough to cite your equally compelling evidence to the contrary.

Submarines are always silent and strange.
