I think that we know all that the Swedes stay there for another year, because the Americans were not able to detect the Götland and need more time to develop a working tactic. We know also, that the main purpose, for the Americans, is to find a solution against countries which own diesel submarines, and more specifically, against countries with Kilo (you know which one I am talking for). In fact, the article makes a reference of it at the end.
Also, the Navy could not acknowledge loudly and publicly that they were unable to track a sub, and a potential threat, that is non-American. So, I would say that Belman is right in is comment.
