How RAF DC-10 tankers would help in the Gulf War

How much would RAF DC-10-based tankers have helped United States forces in the Gulf War?

Tremendously; additional allied tankers would add useful shared refuelling capacity.

RAF DC-10-based tankers would help United States forces tremendously during the Gulf War. Aerial refuelling is a shareable coalition capacity, so the aircraft need not belong to the receiving service for their fuel offload to expand operational options. Extra tankers can support sortie reach and ease pressure on a heavily scheduled common resource. The brief answer remains qualitative and does not estimate aircraft numbers, fuel offload or basing effects.
