A large USAF CORONET mission is currently crossing Europe, involving at least three KC-46A Pegasus tankers (BLUE51, BLUE62, BLUE83) and three KC-135R Stratotankers flying over the Mediterranean area.
The CORONET type of mission usually indicates the transfer of fighter jets or other tactical aircraft from the United States to overseas bases, supported by aerial refueling assets.
In this case, although the exact aircraft being transferred have not been identified, the flight routes strongly suggest that the final destination could be Al Udeid Air Base (Qatar), a frequent stop for deployments toward the Middle East.
The tankers took off from the United States earlier today, crossing the Atlantic, Spain, and Italy before entering the eastern Mediterranean, where several Stratotankers are already operating — possibly to provide refueling support for the last leg of the flight.
At the moment, no fighters have been tracked, but it is likely that they are flying in radio silence or without ADS-B transponders enabled, as often happens during this kind of long-range deployment.

There was something interesting going on on Baltic sea today (and yesterday) as well. US Navy Boeing P-8A Poseidon is still there and seems it had air refueling during the day. Also some Artemis II circling around Kaliningrad.
Correct me, but we can watch this allmost daily Observation Routine since years.
