A Typhoon FGR4 takes on fuel from a Voyager tanker while en-route to Exercise Red Flag in the United States. Air-air refuelling is an integral part of RAF flying operations and Voyagers, operated by 10 and 101 Squadrons at RAF Brize Norton, provide support to Tornado GR4s on operations over Iraq, and to Typhoons on Quick Reaction Alert in the UK and Falkland Islands.
