Thanks.
I’m still getting used to the difference between a fifth generation fighter (aircraft) and whatever comes before them.
Calvin Coolidge said it best: “Why can’t the Army buy just one airplane and let the aviators take turns flying it?” (or words to that effect)
That’s an easy one. 5th gen are mainline fighters designed with stealth/low observability first and foremost, to a degree where they may compromise a bit in other areas of performance, but not always.
