๐บ๐ธ๐ฎ๐ท - It is very likely that American fighter jets accompany the USAF cargo planes towards the Middle East.
Two KC-135R aerial refuelers departed RAF Mildenhall, rendezvoused with two C-17A transport aircraft at about the same time, and followed the same flight path before turning back, leaving the C-17A to continue toward the Middle East.
A C-17A could complete this route without aerial refueling, suggesting that the tankers may have supported a fighter jet deployment rather than the cargo planes themselves.
At this time there is no additional information regarding the movement of fighter jets.
