A new thread with some brief, top level thoughts on the missile statistics. I think people are misreading a couple of the statistics. We are still not that far out from the end of the war, so treat everything I saw as having imaginary error bars of about 10%.
I've seen multiple statements about number of Iranian missiles launched. Some say 500, some say 550, some say 591, some say 631. That's a big delta, probably produced by counting uncertainties.
The some Israeli media says 36 missiles impacted populated areas. There are other impacts at military sites but very few of them did any damage. Impacts on taxiways, things of that nature. Effectively open fields.
The total number of impacts somewhere near something military, industrial, or in populated areas is around 50. This would match what I'm seeing in video and in satellite imagery and has been reported by the IDF. They say over 50 "impact sites" in Israel.
What happened to the other 500 missiles that Iran fired? Most of them likely failed on route. Recall that US and Israeli sources said that around HALF of the missiles fired as part of True Promise 1 and 2 failed on route.
The rest - about 250 to 300 missiles - were intercepted. Israeli air defense has a claimed success rate of about 80-90%, which is born out here. About 50 impacts or so.
Despite some ridiculous claims, Israel is not hiding 250 impacts on things that matter. This would be impossible to remain unnoticed - Israel is a very small country - and not evidenced by satellite imagery.
Basically all the military impacts are effectively misses. The impacts at civilian sites are also largely misses. The Glilot salvo did not seem to hit the intended target for example.
If we are imagining that all impacts of such nature are "successes," then Iranian missiles have about a 9% success rate against Israeli defenses. If we imagine that any success against a populated target is a success, then the figure drops to about 6%.
If we are imagining that damage to a specific military target is the success case, that number drops to about 1%.

Brief, top level review of Iranian missile performance: of the 30 or so hits on Israel, very few missiles actually struck anything important. There are 2-3 hits on Ramon AB, but not on anything important (they hit taxiways), and some possible hits at other airbases.
Once again, the demonstrated accuracy of Iranian missile systems just isn't all that great. Even the big salvo they got through at Glilot shows only 1/5 hits, and that "hit" is assuming the Iranians were targeting a warehouse, which I'm very skeptical of.
I have not seen much evidence of across the board increases in Iranian accuracy - the strikes on Glilot probably demonstrate a ~500m CEP...that's the only salvo where enough things got through for me to even attempt a CEP estimate.

Couple of incomplete thoughts at this point:
Iranian missiles have been, so far, about as effective as previously thought. Huge variation in accuracy, and only some are getting through.
Israeli military capabilities are also basically as good as previously thought. The surprising thing was not Israeli air dominance, but that they chose to undertake a much wider campaign than previously predicted.
I don't have an answer to where the multiple Tor units that are supposed to be positioned around Tehran have gone. I don't think they've all been struck. Possible Iranian air defense C3 has just completely collapsed.

Some notes, given Iran's "new" missile base (I have some theories on where that thing is but nothing definitive) on Iran's missile production:
Iran has at this point rebuilt the buildings destroyed in Israel's raid. There's been what appears to be a lull in production given # of missile crates moving about, but in the grand scheme of things I'm skeptical its going to make that much of a difference.
The fact that the buildings were rebuilt doesn't tell us much - what is important is what was IN the buildings - mixers, casting equipment, etc.

We counted! 32 impact points at Nevatim, with a small degree of clustering. They landed multiple hits in the area of F-35 hangers, with one possible direct hit, but not a lot of damage.
Takeaway: some F-35s got really lucky.
In one instance, two impact craters were observed inside a set of F-35 hangers, just narrowly missing any of them.
Next time, Israel may not be so lucky.
Quantity of near misses also suggests that this was indeed a straightforward overwhelm of Israeli missile defense. Israeli defense sites are not safe from Iranian attack, and if Iran so chose, they could choose a target that would be sure to generate Israeli military casualties.

Short thread on the potential benefits of conducting an abnormal ICBM test like the one the PLARF just conducted from Hainan Island:
Generally the PLARF tests ICBMs from the interior of the country, out in the northern desert shooting east to west. This is satisfactory for most systems tests (many missile tests are actually conducted to test a specific subsystem)
The problem is that this forces you to use a lofted trajectory. Distance from the ICBM test site to the target ranges is around 2000-3000 kilometers, so China has to fire their ICBMs very high to compensate. That's maybe a quarter of an ICBM's actual range.

I've been at it again. Russia is building a deployment facility likely for the operation of the Burevestnik nuclear cruise missile at a nuclear warhead storage facility outside Vologda.
reuters.com/world/europe/u…
Couple of major points:
Nuclear warhead and missile checkout facilities are both present at this facility. This will likely be a high readiness system.
The nine launch platforms under construction, likely for Burevestnik, are fixed. This isn't a survivable target, which worries me somewhat.
