A USAF Northrop Grumman RQ-4B (reg. unknown) has departed this night from NAS Sigonella around 05:45 CEST and it has arrived over the Black Sea at around 10:00 this morning CEST.
Since then, it has been orbiting over the western and central part of the Black Sea.
In the area where it is located, the signal is strongly disturbed (jamming?).
