How much fuel does a f 16 burn an hour?

It can burn it's whole tank in eleven minutes on full afterburner. It would exceed the maximum speed though, and to slow down, G manuvering would be rough on the pilot. Airshow demonstrations of the F-16 use quite a bit of fuel. When the Blue Angels (F/A-18C) Solo's land, they only have about 11% of fuel left.

In a cruise, it will last for a few hours. In a high performance environment, 1.5 hours with external tanks. It really depends though!

$2.94 a gallon for JP-5 fuel!
