I seem to recall reading that the Russians went ape over the suggestion of ASAT, claiming it broke some long standing agreement or other over space weapons, and as such it never reached operational service or largescale production - unlikely to be a serviceable weapon or crews trained in its usage (never mind the aforementioned problem of it only being employable from the F-15....).
Think AEGIS and its SAMs will be the weapon of choice this time, rather than using the experimental(ish) missiles proposed for the missile defence shield.
