@COM9927 IIRC SP aircraft are constructed by the game from XML files, describing everything about the craft.
These can be modified directly, though nowadays the Overload interface is used in-game to change things such as part scale, mass, whether drag is calculated, or a number of other part-specific attributes.
Part health can be increased, though, as far as I'm aware, explosions entirely bypass part health and I think directly destroy connections, which in turn destroy the parts they were joining.

What even is XML modding :/
