That's the hidden story behind carrier ops. Most folks see tanking as a long range, strategic bomber evolution or trans-oceanic transit but it's been the critical element in tactical carrier air ops since the '60's. It's at the pointy end of the logistics fuel pipeline.
If you're airborne during carrier ops there's gonna be a tanker hidden in the woodpile somewhere. Even if there's a weather (and diplomatically approved) divert bingo field available there'll be a ready alert tanker. A fouled deck, a malfunctioning aircraft or a bumfuzzled pilot having a problem getting aboard can happen at the best of times.
The story of air ops in the Middle East and Afghanistan is written in tanker-ed fuel.
It's always fun to be the last, lone tanker airborne when everything goes nuts at oh-dark-thirty in foul weather, you know you're gonna be the last one aboard and there's no bingo field. I've never heard of medals awarded for being a courageous tanker pilot!
