It's more likely something that would make civilian smart tech useless against the top 5-10 militaries. A military guidance system would overtrain a network using a supercomputer and then cryptographically make it stupider so they could give every missile 5 individually generated networks that vote, forcing attackers to compromise 3 networks per missile. (There may be some back and forth for a while, but here you can create a diversity of networks that makes the ensemble hard to attack.) So they'll just shoot them down with lasers cause that's less energy intensive than running the compute node to crack missiles in real time.
