Does anyone know approximately how many interceptors Israel has left? Like has anyone done any analysis on how much interceptors israel bought vs how many Iranian missiles have been shot and intercepted?
THAAD: 1-2 Batteries
1 battery = 6 launchers
1 launcher = 8 interceptors
Assume that 1 battery = up to 48 THAAD interceptors deployed by the US. So between 48 and 96 THAAD missiles.
Patriot PAC-2: 4 batteries
1 battery = 6 launchers
1 launcher = 4 PAC-2s (or 16 PAC-3 missiles)
Each battery has up to 24 PAC-2 interceptors
Israel has 4 Patriot PAC-2 batteries deployed = 4 x 6 x 4 = 96 PAC-2 missile interceptors deployed at any one time
David's Sling: 2 batteries
1 battery = unknown number of launchers (assumed 4-6)
1 launcher = 6-12 Stunner missile interceptors
Each battery has 24-72 Stunner interceptors
Israel is estimated to have 2 David's Sling batteries deployed = 2 x 24-72 = 48-148 missile interceptors deployed at any one time
Iron Dome: 10 batteries
1 battery = 3-4 launchers
1 launcher = 20 missile interceptors Tamir
Each battery has 60-80 Tamir interceptors
= 20 x (3-4) x 10 = 600-800 Iron Dome interceptors deployed throughout Israel at any one time
Iron Dome and David's Sling were not designed to intercept MRBMs, so they are of limited relevance here.
The relevant ABM systems: Arrow 2/3, Patriot PAC-2 and THAAD.
Conservative estimates from Iran's perspective therefore suggest a total number of 326 ABM interceptors (134 Arrow 2/3 + 96 THAAD + 96 Patriot PAC-2) deployed by Israel to counter Iranian MRBMs.
