My answer to How did Russia jamming the Tomahawk missiles cause so many of them (34+) to not reach the target?
Answer by Abbey Laurel-Smith:
Russia did not jam any of the missiles and neither did they attempt spoofing or shooting it down.
This is not the Balkans – where a couple of Tomahawk missiles got shot down, and many spoofed and misled to dummy targets by the Serbs.
Not really sure the current Syrian army have that kind of capability as at now. And if they do, I am sure those resources have been directed towards other things.
On the other hand, what if Russia drone(s) and other assets (mobile indicators) helped guide the missiles to target by either clearing ground clusters and by painting targets to be taken out?
Point is, if all fails, those missiles can think for themselves by adapting to use other ground sources and target identifiers to make it to programmed target. That is what the inertial system is suppose to do.
