2000....
As said, Airbus 330 tanker(s) of UAEAF to support the package of fighters.
Those fighters were not F16s.
They were the other model from the UAEAF inventory, supplied by another great western nation (who has a permanent joint-services base in the UAE)
People from this nation knew more than well about the raid - and US didn't. I can understand their frustration.
Even if you read ....
The officials said the U.A.E. — which boasts one of the most effective air forces in the Arab world, thanks to American equipment and training — provided the pilots, warplanes and aerial refueling planes necessary for the fighters to bomb Tripoli out of bases in Egypt. It was unclear if the planes or munitions were American-made.
Equipment and training is not a US privilege, even if so many would like to believe it. So it was perfectly clear which aircraft were involved, but how unpleasant to swallow for them, apart from being left in ignorance.
United States diplomats were fuming about the airstrikes
That's a good summary
