A slightly uncanny part of this is that the focus is on an area outside of Kronstadt naval base (star). Not in the base, but waters outside.
Do excuse the hack shop job and faulty angles.
USAF RQ-4 surveillance drone FORTE11 spent 16h over Estonia and is about to return home to Sicily.
Later in its mission it angled even more west. This + yesterdays focal point outside naval base indicates to me they were watching naval units on the move out into Baltic Sea.
Range reference, in other words, they might have looked much further than what I propose above.
This official news on an exercise held outside Kronstadt is consistent with guess above. Albeit a date is bot mentioned, so more likely that was the day before the RQ4-mission.
* It is unusual to not see daily sanctioned tanker arrive to Baltic Sea, usually a few each day.
But, the last 4 days lull ismight be explained by weather: Atlantic storms, low temperature and an increasingly frozen Gulf of Finland.
The ice is growing thicc around Russia's Baltic oil terminals.
Ice data outlets list a bunch of ice-breakers in service, but other sources have stated Russia lack capacity to keep the ice-sensitive rust-bucket tankers in play.
ASTROL 1 is a largely flat cargo ship with hatches that likely would serve well as drone pads.
She is a similar model to SCANLARK, recently apprehended by German authorities on drone suspicions and to PORT OLYA 4, drone import ship on Iran trade. Sunk by Ukraine.
