The F-16 is the only fighter around that can take 9g’s.Probably more than the pilots can handle.But for a dog fighter its one of the Best.
I don’t think the F-18 even gets close.
In this documentary about the dogfights of Desert Storm they mention at around the 17:30 mark that an F-15 took 12gs in a Split-S maneuver.

All fighters, except the A-10, are rated at 9-g’s for everyday flight.
They can go higher but need an NDI before the next flight.
Thing is, the F-16 is controlled by a computer so the jet CAN’T go above 9-g’s if demands by the pilot. Other fighters can.
