On December 05, 2017 three F-15SAs for the Royal Saudi Arabian Air Force arrived at Lajes in the Azores as part of their delivery flight.
The aircraft involved were:-
12-1053 "Retro61"
12-1056 "Retro63"
12-1057 "Retro62"
Tanker support was provided by KC-10A 84-0192 "Gold22"
Six F-15SAs were due to arrive but as of December 07, 2017 three remained on the east coast of the United States. The three that did arrive at Lajes were still present on December 08, 2017 so it is likely that all six will continue their delivery flight together.
