Russians claim the missile that struck the Okhmatdyt Children’s Hospital in Kiev yesterday was an American-made air defense missile. It wasn’t; video footage clearly shows that it was a Russian KH-101.
To help everybody not get fooled again, I’m going to explain some basic differences between ground-attack and air-defense missiles, and why nobody should have been fooled by this propaganda for a second.
The top-line thing here is that ground attack missiles can be large and have heavy warheads, while air defense missiles have to be smaller and have lighter warheads.
Air defense missiles have to intercept a target traveling at high speed. They have to be as fast and agile as possible in order to do that; every gram of weight is a penalty. That means you’re going to make the warhead no heavier than you have to in order to kill a plane. And it doesn’t take much kaboom to kill a plane.
Even if we didn’t have footage of the missile and wreckage to examine, it would be obvious that the damage to that hospital wasn’t done by an air defense missile because there’s too much of it. You can’t get that much blast shock out of the smallish warheads they put in those things.
The weight penalty for a big warhead is much less in something like a KH-101. It’s not designed to be agile, it’s designed to get from point A to point B on a least-time course and then blow up real good.
You can use an air defense missile for ground attack with some hacking of the guidance software, but you can’t use a ground-attack missile for air defense; the physics are against you.
The problem with using an AD missile for ground attack is it it won’t give you much of a kaboom when it gets there. They’re just not very effective.
Nevertheless, the Russians have actually been doing this in Ukraine, throwing S-300s and S-400s at ground targets. Only because they were short on ground attack missiles to start with, and their capacity to manufacture them is limited by Western sanctions on the electronics they need.
So the next time the Russians try to deflect blame for one of their missile strikes on civilian cities by claiming the explosion was from a failed Ukrainian intercept, treat the assertion with the contempt it deserves. If whatever went boom actually was an air defense missile, it was almost certainly a repurposed Russian one.
