Not only does this translation fumble the translation of the word "naval mines", which amusingly becomes "minors", but it also somewhat surprisingly changes the nationality of the military power involved.
The correct translation should be:
> The analysis shows that it is a Swedish remote-controlled craft (Seafox) that the Swedish Armed Forces use to detect, for example, naval mines.
How is that just dropped in there without any explanation of an innocuous purpose of an explosive laden drone?
News is full of "it's just a coincidence, look away" -- speculating is fun, but don't be a conspiracy theorist. Always listen to approved, fact-checked news sources. They'll tell you what to think.
And in this case you need to look at this as anything but sabotage.
