Iron Dome:
20 missiles per launcher (+ reserves and inventory for re-loading)
3-4 launchers per battery (60-80 interceptors per battery)
Israel is thought to have 10 Iron Dome batteries deployed across Israel
20 x 3-4 x 10 = 600-800 Iron Dome interceptors across all of Israel at any one time
assume at least 50% of these batteries are facing the north to protect Haifa, Acre, Safed and north Israel generally = 300-400 Iron Dome interceptors available to face Hezbollah rockets at any one time.
Hezbollah has truck based rocket launchers capable of launching 40-70 rockets per vehicle. 6-7 of these vehicles each launching 50 rockets in parallel would be sufficient to deplete entire Israeli Iron Dome interceptor in operation in the north (at a time, until Israel reloads them). If Hezbollah has even 20,000 such rockets (very conservative), in a full scale war we can assume serious degradation of Israeli Iron Dome capability after at most 30-50% of Hezbollah's rockets are used (10 total reloads of all 10 Iron Dome batteries across Israel).
What are the numbers for Patriot, David's Sling, THAAD and Arrow-2/3 in Israel? @Nuffle
2:1 ratio vs only firing against rockets headed for urban areas could plausibly offset each other2 interceptors are launched for every 1 rocket by Iron Dome. However, the targeting radar for Iron Dome only launches interceptors for rockets that have high statistical probability to land in population zone. No one knows the exact logic algo for that. But rockets that will land in open fields and away from threat zones do not have interceptors fired.
So given the wide inaccuracies of Katyusha rockets, HZ would need to fire much more rockets to get Iron Dome to waste more interceptors. Or it will need to move to more advanced rockets like Zezal series.
You can't trust The Military Balance 2024 too much, but they are:Iron Dome:

What are the numbers for Patriot, David's Sling, THAAD and Arrow-2/3 in Israel? @Nuffle
The US sent THAAD to bolster Israel's defenses in addition to additional Patriot batteries. Recent news that a US Navy CG is also close to Israel for protection.
1 THAAD battery - 6-9 launchers with 8 missiles per launcher
1 Arrow 2/3 batteries - 4-8 launchers with 6 missiles per launcher
1 Patriot battery - 8 launchers per battery (16 PAC-3 missiles per launcher versus four PAC-2 missiles per launcher)
1 David Sling battery - 6 launchers with 12 missiles per launcher
1 Iron Dome battery - 3-4 launchers with 20 Tamir interceptors per launcher
I don't know about that, I know they have based THAAD in Saudi Arabia. In Israel, the Americans have 1 AN/TPY-2 X-band radar at Mount Keren.
Jordan: 2 bty M902/M903 Patriot PAC-3/PAC-3 MSE
Kuwait: 2 SAM bty M902/M903 Patriot PAC-3/PAC-3 MSE
Qatar: 2 SAM bty M902/M903 Patriot PAC-3/PAC-3 MSE and 1 AN/TPY-2 X-band radar
United Arab Emirates: 2 SAM bty M902/M903 Patriot PAC-3/PAC-3 MSE
Saudi Arabia: 1 SAM bty M902/M903 Patriot PAC-3/PAC-3 MSE and 1 SAM bty THAAD
Here is an interesting analysis of ABM/AA capacity:Since the US promises to help Israel under the command of CENTCOM, the US can probably provide some type of early warning due to its orbital surveillance system that detects missile launches leaving the atmosphere.
Tracking would be carried out by the organic radars of the Patriot system and the THAAD that they operate and perhaps by some long-range ground-based radar.
The bad thing about the Saudi Patriots is that they are, unless I'm mistaken, the PAC-2 version, and are not effective against medium-range ballistic missiles (MRBM).
PAC-2s are best suited to act against tactical ballistic missiles (TBM) and short-range ballistic missiles (SRBM).
They are complemented by THAAD which are capable of engaging SRBM, MRBM and IRBM missiles.
10 Iron Dome batteries seems accurate and widely reported (as of mid-2021, could be 12 now if US sent 2 more batteries, not confirmed)You can't trust The Military Balance 2024 too much, but they are:
3 bty with Arrow 2/3(probably 2 Arrow 2 batteries and an Arrow 3 battery)
4 bty with M901 Patriot PAC-2
2 bty with David’s Sling
10 bty with Iron Dome

MDAA says 3 Arrow-2 batteries and 3 Arrow-3 batteries. What's your source for 3 batteries in total?
MDAA also says 3 Patriot PAC-2 batteries, where is your source for 4?
David's Sling is designed for Hezbollah Fateh-class SRBMs and cruise missiles (but so far only used against Hamas rockets), so unlikely to be useful against Iranian MRBMs
Potential countermeasures to Iranian MRBMs: Patriot and Arrow (and maybe THAAD if Israel has it)
Maybe we should start a separate thread to assess the deployment of Israeli air defence systems

Thanks. No THAAD in Israel is confirmed?The source is The Military Balance 2024:

As I said, you still can't trust these numbers. The delivery of the third battery of Arrow 2 was speculated and as Israel had already received the first launcher of the first battery of Arrow 3 in 2017, TMB 2024 would have to be informing that there are 4 Arrow 2/3 batteries. In any case, we are approaching the number close to Israel's anti-aircraft defense.Thanks. No THAAD in Israel is confirmed?
