On the night of October 27-28, 1981, an incident occurred in Swedish territorial waters that had still really invaluable consequences: next to the Karlskrona naval base of the Swedish Navy, in those days when some new Swedish torpedoes were being tested (according to Swedes, at least), in an area with an extremely difficult fairway, where, according to the Swedes, it is impossible to get into by accident, the Soviet diesel-electric submarine S-363 of project 613 ran aground.
The history of this incident has been sufficiently highlighted both in the press and in the memoirs of the submarine veterans. There is no need to waste time discussing it - Russia still claims that this was the result of a navigational error, those who served in the Baltic Fleet in those years tend to the same point of view, also mentioning the slovenliness of the crew (there is, however, no reliable evidence of this), while the Swedes are sincerely convinced that this was a Soviet reconnaissance operation, and that the boat had at least two torpedoes with a nuclear warhead on board.
But what happened after that is much more interesting. And after that there was a lot of things, and most of this "a lot" in our country, unfortunately, is completely unknown and not realized.
Sweden geographically dominates the Baltic Sea on the one hand, and is not part of the NATO bloc on the other. This neutrality, I must say, is very "pro-Western" - so the Swedish submarine "Gottland" was based in the United States for several years, where the Americans honed their PLO on it. But the degree of "pro-Western" Swedish politics is now much higher than it was at the end of the seventies. And the reasons for this are closely related to the incident with the C-363.
Since the sixties, suspicious to paranoia Swedes (for example, for them the norm of systematic mining of their territorial waters - just in case) recorded six incidents, which they designated as incidents with submarines, sequentially in 1962, 1966, 1969, 1974, 1976 and 1980s. Five incidents in 18 years. At the same time, the incident in 1966 was a multi-day chase, using depth charges against a foreign submarine. To discover, however, nothing was possible. The case of espionage by a Soviet submarine on the border of Swedish territorial waters, with the subsequent entry into them, which frightened the Swedes, stands apart - this was a rare case when a submarine was identified. And then - S-363.
It is not known exactly whose submarines the Swedes had discovered before, and some facts of the discovery can generally be questioned. But after the S-363, the Swedes seemed to have broken through.
After the S-363, the number of foreign submarines in Swedish territorial waters increased sharply, and evidence of more insolent specials began to appear. operations of foreign navies. Mindful of the S-363, the Swedes blamed the entire responsibility on the USSR, and more and more drifted into the arms of NATO.
Here is a list of incidents in the eighties:
