G-limiting
It stands to reason, which you were of course getting at in the first place, that aircraft are limited if carrying stores.
There is a relatively recent film of a Wart-on Harrier ( they don't know what to do with it up there apart from chase Whippets ) which departed in a big way & folded the pylons flat under the wing.
Also possibly more to the point, a Sea Jet years ago did a high G pull, resulting in lofting drop tanks, I believe complete with pylons, into a chap's Asparagus bed...
Most if not all fast jet a/c are limited to around 3g until the droptanks are empty or disposed of - rare due to cost unless in real combat - as aerodynamic loads soon come into the equasion.
