It took them this long to confirm something that they might have seen last October?

Stockholm (AFP) - Sweden's military on Sunday confirmed a second sighting in October of what appeared to have been a submarine in waters near Stockholm city centre, not long after a search had been launched for a suspected Russian submarine off the coast.

In November the Swedish military released images of tracks on the sea bed and an apparent submarine periscope which it said proved that "a mini submarine violated Swedish territory" between October 17 and October 24 and that "at least one vessel" was involved.

However, despite widespread speculation that the submarine was Russian, the military never identified its nationality.

On Sunday, Swedish daily Dagens Nyheter revealed that a member of the public also photographed what appeared to be a submarine tower on October 31 about two miles (3 kilometres) from the city centre, close to busy ferry traffic lanes.

Sweden suspects up to 4 subs violated its waters – report

The Swedish military now believes that not one, but up to four foreign submarines were operating in the Stockholm Archipelago in mid-October last year, a source within the country’s armed forces said.

An unidentified sub was allegedly spotted in Swedish waters on several occasions, October 17-19, 2014.

This led to a two-week submarine hunt, the Swedish military’s largest operation since the Cold War, but it turned out fruitless, despite the media hype.

Earlier this month, the Swedish military said it spotted another foreign sub in its territorial waters on October 31 and organized a search operation, which also proved futile.

Finnish navy drops depth charges onto suspected submarine in its territorial waters
The Associated Press

HELSINKI – The Finnish military says it has dropped depth charges onto a suspected submarine in the sea outside Helsinki after twice detecting the presence of a foreign object in the area.

The navy’s maritime operations chief, Olavi Jantunen, says they could not identify the “underwater object” but had begun an investigation, which could take weeks.

Parliamentary defence committee spokesman Jussi Niinisto said Tuesday that the military occasionally detects such activity but described the use of depth charges as unusual.

The intrusion comes in the wake of a lengthy hunt for a foreign submarine in Swedish waters in October following increased military activity in the Baltic Sea region.

Swedish officials never blamed any country though most defence analysts said Russia was a likely culprit.

Apparently Finland is upping the game and dropping "depth charges" on the submarine(s) probing about various Scandinavian waters.

I suspect "depth charge" is not really the best label ... it sound like more of a pyrotechnic than a weapon.  Could these just be diver recalls?

More than likely it was something along the line of a SUS (Signal Underwater Sound), which is handheld and has a small explosive charge.

if this keeps escalating eventually a sub will turn up.....in pieces

Do a Notice to shipping "Depth Charge exercises at X between time X, exactly 15 minutes before you drop a real depth charge.

Bingo. 

Finns drop warning charges after possible sub sighting off Helsinki

"Well, we ran out of signal charges, so I guess we'll have to use the depth charges."  ;D

Now the media can stop panicking that Putin may have lost a sub off Scandinavia. (Unless you count Putin as a Czar himself  ;D  )

Sweden Says Sub Wreck a Czarist Russian Vessel
STOCKHOLM — Sweden said on Tuesday the wreck of a submarine found off its coast appeared to be a Czarist-era Russian vessel that collided with a Swedish ship about a century ago.

"We are most likely talking about the Russian submarine the Som (Catfish) which sank after a collision with a Swedish vessel in 1916 during World War I and before the Russian revolution," the Swedish Armed Forces said.

Speculation had been swirling about the origins of the vessel after Swedish divers announced Monday that a submarine had been found about 1.5 nautical miles off the coast of central Sweden.
