It is notable how many missiles have gotten through in the past few days. It’s not like unbelievable amounts of missiles are getting through, but for three weeks the only missiles that were getting through is Israeli defenses were the cluster munitions but over the past week at least three or four conventional ballistic vessels have breached Israeli air defenses and caused significant damage and injury.
Edit: I deleted my comment about the possibility of it purposefully not being intercepted. I think the interceptors missed. I was just saying until we know what was hit, there is a chance it was intentionally ignored, even if that was likely not the case.

I’m wondering if we’ve all been mislead about interceptor capabilities, and ‘enemy’ Iranian capabilities? And to what extent? I’ve seen lots of interceptions, but mostly against home-made hamas water pipe missiles, and some rare exo-atmospheric interceptions which are almost works of art. But did I just see a ballistic missile maneuvre at low altitude to avoid interception? I honestly don’t know. But I do wonder.
Edit: Some kind of Reddit rules’ policy was changed or adapted, so I post again.

I think Iran has some good missiles. What you have to understand is that the interceptors are calculating the trajectory of the missile constantly. What the interceptors are actually tracking is what’s called an along track and cross track acceleration. Think of either side of a curve. Another analogy is how tanks turn. A tank is on two tracks and if it’s driving straight at a rate of speed, the process for it to turn is simply slowing one of the tracks. So if you wanted to track the movement of a tank, all you have to do is measure the rate of change of each track in either direction.
If you want to measure the trajectory of a missile, where it’s going to be. You have to estimate its position and velocity. And the noise at a very finite level it produces. This velocity can be converted into a heading. The raw curvature which is a second derivative of momentum, mixes two different questions of am I speeding up or am I turning? Aerospace engineering splits acceleration into thrust, which is along the flight path and lift which is perpendicular to it.
If you take this projection and measure it into a beam that encodes confidence. You now have a trajectory of where the missile is headed. The missile interceptor has to perform its own similar calculations to be able to adjust its own trajectory so it’s headed an optimal position of interception.
It’s hard to tell because the guy filming is rotating horizontally as the missiles are coming in, but I think you can tell what’s happening. I believe what is happening here is that the approaching Iranian missile is heading in one direction and as it’s approaching, it’s banking and turning and makes final adjustment as it enters what’s called its final velocity state which is the strongest most accurate point of precision to the target. It only appears as a very slight adjustment to the trajectory of the missile, but it’s very precise. If there were smoke contrails, you’d be able to see it.
The missile interceptor also is doing the same thing here in the video where it looks like it’s altering its trajectory but calculates the wrong precision point. This video is a really good example minus it being dark because you can watch the missile and missile interceptor approach each other in equivalent tangent velocity states.
This is a battle after all, and someone has to win and that happens to be the Iranian piss missiles. It’s fascinating, watching these missile versus missile interceptor videos. Tracking missiles, tanks, and planes is just math.
