I don’t know about that. There are a lot of ‘bent & cracked’ airframes that are red lined below their designed g-limits (among those older aircraft). That’s why the USAF is buying more F-15’s to replace the old F-15C’s. It’s an affordable stopgap solution to keep the available airframes from cratering.
I was thinking more of the Herc and BUFF in their various configurations, but you’re right - the higher-G airframes take a beating.
