2017-03-29 During an October 2016 exercise in Japan, RAF Typhoons from RAF Lossiemouth operated with the Japanese Self Defense force in a joint exercise.
According to an RAF story published on October 22, 2016:
Royal Air Force Typhoon fighter jets and a Voyager aircraft have landed in Japan.
Four Typhoon fighter aircraft, flown by No 2 (AC) Squadron pilots from RAF Lossiemouth, arrived at Japan Air Self Defense Force (JASDF) Misawa Air Base, in the northern part of the island of Honshu on Saturday.
An RAF Voyager from RAF Brize Norton, crewed by No 10 and !01 Squadrons, provided air-to-air refuelling during the 3,500 mile (5,600 km) non-stop flight from Malaysia.
This marks the first bilateral exercise ever in Japan for the JASDF to host with foreign military other than the U.S. The Exercise, named “Guardian North 16”, represents an opportunity for both air forces to learn from each other and develop their skills.

We interviewed participants in this exercise at RAF Lossiemouth and will report on those conversations later this year.
For now, one should note that the Typhoons came with a single Voyager which carried not only the fuel, but personal and equipment to support the exercise.
The photos below show Typhoons being refueled by a Voyager aircraft on their way to Red Flag in 2015 which shows how the two aircraft working together give the RAF a real expeditionary capability.
