Bayern Chemie has some interesting work published on VFDR based Surface to Air interceptors but given that most of those that could create such a system, are busy with currently approved projects I don’t see it anytime soon. Ballistic Missiles are covered in the US (ICBM will require some time still) and limited capability will be available across the threat range in Europe as well. AAW capability is there in virtually all interceptors ranging from 20km to around 160km. What the Western Air Defenses need quite urgently is a US Stunner/PAAC-4 class interceptor that is low cost and that can deal with the cruise missile (and cheap TBM) threat more efficiently. I don’t see how VFDR can help in that.
