Yeah. I'm a bit worried about that. But I also think point defense and missile defense should be one thing, and its silly to be using powered missiles to intercept missiles. It might be possible to save the navies with better PD. But it also might be better to skip the water navies and instead make orbital missile platforms. Of course, that would be even more expensive, but f it, it would be cooler, and we need an excuse to do more stuff in space.
