The US Navy doesn't build them, private companies do. None of the SMR companies that I am aware of have attempted to use designs from naval reactors. Perhaps it has something to do with the fact that they use highly enriched fuel which is a no-no for civilian reactors.
In any event, if your more general point is that naval reactors indicate its possible that SMRs can be built on time and budget, I don't disagree. It certainly is possible. NuScale was the furthest along of the SMR companies and had their project implode before it got off the ground. So, its also possible for them to crash and burn.
So, I'll stick with my classification of SMRs as "maybe it will work out, maybe not".
