the P47 "the Unbreakable"no more

As a G-load related aside ...

... it should also make a difference where the extra weight (bombs) are carried. The airframe should be able to pull more Gs with a 500 pounder under each wing versus a single 1000 pounder on the centerline. Spreading the weight across the span reduces the peak load at the center.

This is assuming the shackles aren't themselves the G-load limiting factor.
