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.
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.
