Do you know if that was fully custom hardware? Or what I'm specifically asking is: was the problem that the available hardware is not produced to withstand 40kG, or that they can't produce hardware able to withstand it? Because there latter sounds like a serious problem, but the former sounds like it could be solved with money spent on it.

For cost purposes they started out with mostly off-the-shelf components and then they slowly replaced those components that could not withstand the stress with custom kit. IIRC just casting some components in sturdy resin was often enough. Bad for the thermals ofc, but it only needed to run for a few minutes anyway. I left the navy a few years ago but since the product is now apparently ready I assume that they managed to solve all remaining problems. (Acquiring a GPS signal quickly enough from a high speed projectile was not trivial either)
