My unnerstaning is one of the newer PLA anti-ship "ballistic" weapons has a terminal guidance kit of some sort, and the Iranian folks seem to buy stuff from that source. So it's not out of the realm.
OTOH some of the U.S. 'theater" defense systems have a decent near-exo atmosphere intercept capability vs low numbers of an attack salvo. And then there's the closer engagements by systems such as Patriot, et al.
Gums postulates...
