Recently I read news about the US air force is conducting side by side comparison of F-35 vs A-10 in close air support just to see who is better at the job. In my opinion, it is obvious that the less than 200 rounds of 25mm shells of F-35 is not up to the job of true close air support. It might be enough for one pass or two at most, but F-35 is too fast for accurate firing, and it is not as tough as A-10 in the term of taking ground fire. It also can't carry as many missiles as A-10. So what is the point of comparing when the answer is obvious?
