Not yet, partly because Navstar isn't really operational yet.  But the
next generation of missile guidance systems will probably use it for
occasional updating, at least.

The existing Soviet Asat system is good only in low orbit, and the
Navstars are somewhat higher up.

I agree that it doesn't sound like a wonderful idea, though.  Navstar
is unfortunately one of these systems that gets enshrined as an official
panacea for all (in this case, navigational) ills.
