Well, I know that Bull had experimented with both liquid, solid, and
explosive based maneuvering systems in his work at his ranges in Canada
and Dominica. He also pioneered work on hardened electronics, which
really isn't that tough: you immerse it in an epoxy much as many
electronic ballasts are for fluorescent lights, hold it under high
pressure as it cures. The chamber the electronics sit in are lined with
a deformation layer that deals with thermal and shock created
deformation, so this doesn't shatter the 'block'.
G hardened electronics are not a matter of possibility, merely practice.
BTW: the big Babylon gun design did not use a single charge, it had
staggered charges along its length that would go off as the projectile
passed, thus reducing peak G forces.
