What is Israel’s Iron Dome? Here’s how the missile defense system works

There's no saturation attack when missiles are launched from a very long distance like from Iran, and are thus by their nature big and expensive. Distance is also not long enough to give enough time for MIRV to properly work.

Big question however is whether it can launch on remote using some bigger radar, or with slow interceptor flight vs incoming warheads, there won't be much area it can cover.

tguvot•7mo ago
saturation attack has nothing to do with distance and everything to do with number of missiles shot. it's attempt to either exhaust stock of missiles in active AD batteries or overwhelm tracking capacity of AD systems/radars.
anovikov•7mo ago
That's my whole point: it DOES have to do with distance because any ballistic missile that can fly that far away, is bound to be large and expensive. One can't launch too many of them - especially not in short order because installing a new one onto the launch pad takes hours. It takes a lot less time to reload interceptor battery.

But the trick is ability to launch on remote, or the protection envelope will be nearly nonexistent.

tguvot•7mo ago
last year they launched ~180 at once. they have more mobile launchers and underground launch pads so they probably can shoot even more.

any of the strikes that they made, even smaller one with 40 missiles would have devastated any city in any other country.

anovikov•7mo ago
Oh that's not a lot at all. A single Iron Dome battery has 60-80 missiles and of course no one is going to launch entire barrage in one place at once (plus, overall stocks of missiles can't be high, i mean even Russia can't manufacture more than ~1.5 Iskanders per day, and those launched from Iran must be more expensive simply because of size).

As we can see, a smallish minority of them slip through so any damage to Israel can only be psychological/due to disruption of civilian life because of sheltering, disturbed sleep due to alarms etc. No actual damage as in - meaningfully reducing Israel's capacity to wage war, is possible.

tguvot•7mo ago
iron dome doesn't intercept ballistic missiles.
anovikov•7mo ago
Apparently, after 2021 upgrades, it does. Videos of Iron Dome use have been posted multiple times in the last days and Israel was only under attack from Iran ballistic missiles.
tguvot•7mo ago
No, it doesn't. Check Wikipedia
treesknees•7mo ago
From Wikipedia, “During Iran’s Operation True Promise III Iron Dome was found to have intercepted 20-30% of ballistic missiles.[199]”

[199] https://bulgarianmilitary.com/amp/2025/06/15/iron-dome-shock...

> This unexpected success, rooted in years of technological evolution, underscores a broader misunderstanding of the system’s capabilities and its place in Israel’s defense architecture.

So per your own source, it indeed can and does intercept ballistic missiles.

tguvot•7mo ago
yeah. "bulgarian military"
treesknees•7mo ago
I’m not sure what you’re implying. Are you suggesting that the source on Wikipedia is unreliable? Why would you recommend reading Wikipedia in this situation?
