I forget which fighter they were talking about for close ground support maybe a decade ago, but it could only have sustained gunfire for 4 seconds, and the A-10 for over 16. Does the F-35 even have guns? Or would it just be a load of missiles?

F-35 does have a gun. Whether it should or not is another matter.

Most fighters have very limited cannon fire duration. It's less than a second for F-15 and F-16 IIRC, they only carry about 500 rounds. The M61 is a 6,000 round per second minute cannon (thanks Joe), so you do the math.
