One thought struck me this morning.
At the point when the Swiss ship was sanctioned off the job and given the Russians knew the full capabilities of the Fortuna, was the move of the AK from the Far East to the Baltic a skillful piece of distraction, drawing all the attention in Washington in particular onto it? On the lines of 'look at this shiny bells and whistles ship, just like the one now gone, that we must need because we are bringing it half way round the World and protecting it with RuN escorts, not that old barge over there'. Then when it arrived maintaining the story for as long as possible with some work. Thus allowing the Fortuna to quietly get on with the job until it reached the point of no return when the US woke up and went for more sanctions.
Genius level diversionary tactic if I'm right and we here certainly helped it along. Even if I'm not, its still doubles all round on the house tonight at the top of the Russian power structures. Even some champagne, Russian of course
