There's lots of pushes to add software to more of the military, but I don't think these kinds of resilience questions are really taken seriously. A system intended for wartime use will be running in non-optimal conditions while under constant attack. But many of these "enterprise" systems barely work better than paper to start with.
I think that's changed a bit - witness how reluctant the US gov is to be locked into Anduril Lattice. I think we'll see this start to change but certainly a lot of bad past decisions to make up for.
