The Swedish Armed Forces confirmed that a submarine has violated Swedish territorial integrity. Results from the analysis following the intelligence operation conducted in October are unambiguous.
Supreme Commander Sverker Göranson said:
There is no doubt, we have excluded all other explanations. Swedish territory has been seriously and unacceptably violated by a foreign power.
On Friday the 17th October the Swedish Armed Forces received credible information on foreign underwater activity in the Stockholm archipelago. An intelligence operation including naval, ground and air units was initiated immediately. Apart from the military resources, observations from the public provided important data.
The decisive observation is made by the Swedish Armed Forces’ sensors. It is a result of a highly skilled operational conduct. The observation meets the requirements for the highest level of assessment grading, confirmed submarine.
The analysis cannot determine the nationality of the intruder.
In addition to the decisive observation, a number of other observations have been analyzed and reach the second highest level of assessment grading. A picture taken by a member of the public shows an object moving at a speed of approximately 1 knot. The picture also shows the kind of spray that arises when water is pushed out of scuttles at the top of a submarine.
A second observation was made by a naval corvette. Following strong indications on its sensors, a closer examination of the area was conducted and recently made traces were found on the bottom. Another observation was made by a resident in the archipelago, observing an underwater body with distinctive features. Sensors from the Swedish Armed Forces also confirmed echoes in the area. Similar observations were made by multiple credible sources.
Each of these observations has a high credibility. Together with other observations, and a confirmed submarine, they generate a pattern. Thus, the intelligence operation confirms that a foreign power has violated Swedish territorial integrity. The gravity of this is obvious.
