8 hours flying time would mandate pre-strike & post-strike refuelling.
The tanker would most likely be an RAF Voyager aircraft.
The Voyager is a probe & drogue refueller based on the Airbus 330.
I wonder where the Voyager orbited while the Typhoons hit their targets...most likely in Saudi airspace.
