I'm tentatively labelling this "f-15" even though I'm pretty sure the Eagle refuels using the USAF refuelling system rather than the RAF "suckling" system depicted here.

She is F-22. See post #738401 and post #617603.

I stand corrected on the aircraft model.

So, can anyone say whether the USAF has switched refuelling interfaces?

USAF aircraft use the flying boom system. But, the tanker with a flying boom can be equipped with a drogue adapter for probe-equipped aircraft.

Yep, it's the Navy that loves the drogue so much. The Air Force uses the boom.

"This is fuel"

Fetish fuel, played straight.

So this is the moe antromorphism of the Decepticon Starscream?
