Iranian Air Defense Systems

I updated my Bavar-373 article with analysis of the new information, text is below. Full article at https://irangeomil.blogspot.com/2019/08/irans-bavar-373-profile.html

Update 4th January 2022
Bavar-373 has appeared on the Ministry of Defence's export page as AD-200, with a detailed specsheet improving public understanding of the system, specifically the Sayyad-4 missile.

The missile's basic proportions are very close to the 48N6E2 missile used in the S-300PMU2. Sayyad-4 has a large 180kg warhead, the same as its Russian counterpart. It has the same airframe diameter and length (not including aerodynamic control surfaces) as the 48N6E2, but is 150kg heavier at 2050kg. Despite this, it has a 200km range to the 48N6E2's 195km. This kinematic performance is quite impressive considering the extra weight, and it is reasonable to assume that later versions of the Sayyad-4 will reach similar performance to the more mature 48N6E3.

The main difference between the two is the seekers. The 48N6E2 found on the S-300PMU2 already had a very robust mode of guidance called SAGG. With the release of the specsheet, this guidance mode can also be confirmed on Sayyad-4, which has "Inertial + Update Via Data Link Semi-active". On its own, that description would describe at least a TVM system as used on the MIM-104 Patriot PAC-2. TVM sends receiver data back to the ground radar via a datalink. The ground radar then calculates the appropriate guidance commands and sends these back to the missile.

However, the specsheet says "Semi-active/ Active Radar Homing". Active Radar Homing uses a self-contained radar set which none of the 48N6 series use. ARH on long-range missiles is a feature also used on the 40N6 missile of the S-400. This also confirms that Sayyad-4 would have onboard computation, making it capable of SAGG. SAGG is best described as a more robust form of TVM, because in addition to the raw receiver data sent to the ground radar, the missile can calculate its own guidance commands, which can be datalinked to the ground radar to check for errors between the missile-computed commands and the ground radar commands. The missile can also act on its own if guidance commands from the radar are being jammed but the target is still being painted by the ground radar.

However, when defending against the S-300 or Patriot series, a defending aircraft could hide below the horizon or behind terrain to break line of sight with the ground radar. This would defeat even SAGG, which is fundamentally a SARH-based guidance mode relying on line of sight. By including an active seeker, Sayyad-4 has the ability to guide on to the target even if line of sight to the ground radar has been broken in the little time the target has to react. The use of inertial guidance also allows the ARH mode to be used based on the target's predicted flight path at the time the radar lock was broken. This is particularly useful in Iran's mountainous terrain, but also makes Bavar-373 potent in naval applications where most targets will drop to very low altitude in the final phases of flight. Bavar-373 has clearly been designed for maximum resilience against jamming and reducing the ability of the target to defend to an absolute minimum.

What is thé adress if the defense ministry catalogue ?
 
Our trained friends defined something for the S300 that was not defined in Russia itself. We received the upgraded PMU2 S300 but changed it according to our needs. Of course, we also changed the S200 system with a very high percentage, and even fired medium-range missiles with it.

One of the most important statements of the interview in my opinion. Although the S-300 PMU2 Iran received was not an export version, it's great to learn that on top of this, Iran modified the system. Now the relative bonus NATO and the zionists enjoyed from training against S-300's in places such as Greece is neutralized. They will not know what exactly they are up against, may find it more difficult to jam etc.
 
Hello gents, do any of you know What is the address of the defense ministry products catalogue?
 
If Iran and Israel start a war in a hypothetical scenario None of Israel's future attacks start with IAF attacking Sam, instead they use cyber relam, they possibly try to sabotage or delay the sam systems responses so their strike packages can have safe pass, hence Iran is very large country they need huge number of long and medium range Sam Batteries to cover all possible entering zones and overlapping them as redundancy, Irans air defense look pretty impressive but they need more in numbers, but even in low numbers Iran's AD won't be a cake walk for IAF, they may have Successful strike but they will loose 2 or 3 birds from each packages minimum

Exactly what was I thinking.

Hajidadeh is talking about strategic missile in air defense field.
Number of missile on one TEL depend on system performance, and you always must look at least one whole battery to understand. For example one Buk M1 system. One. battery needs has one Command post and you need only 1 TEL with radar, and that one can BE linked linked and can Control and guide missiles from 3 more TELs without radar dome... SO one Buk battery has 4 TELs....mostly 3 TELs with radar dome and one without that serve as TEL and transloader... But it is meaningless to put 8 missiles instead 4 when Buk has 2 channels and you can engage Limited Number of targets. It is always better to have 2 x 4 missile TELs than 1 x 8,you have redundancy and more dificult for Enemy to target 2 than one TEL. So they decide AD deployment design and num# missile on TEL with performance, doctrine and deployment in Mind. It is better for mobilne shorad to have 4 compatibile missile containers on every TEL since it is easier to maintain and reload, thus you have more TELs on different positions... Now, Russians designed some of their Shorad with offensive deployment in Mind, their doctrine in Europe is built Around plans, in case of war, to overun eastern Europe with large armored units(that is why they maintain that Crazy Number of MBTs), SO they need highly mobilne tracked Shorad that can follow armored units, also that is why they insisted from begining on fire on the Move capability Also that is why Russian ground force have own AD from shorad up to S300V... That is because their doctrine include fast movements in to deep Enemy teritory... So ground forces have own units up to IADS....Iran doesnt plan to do that, Iran has defansive doctrine and need differnt capabilities...So we will see different arrangement for Iranian SAMs...

no its not meaningless , mor missile means you can engage more wave of attack , don't forget the system can always engage another targets when the previous one is destroyed but having have to reload take time

You didnt understand my point...they will always deploy same number of missiles ready to fire,it will always be max missiles can be online per battery,it is just metter will it be 16 missiles on 2 TELs with 8 missiles each(number is example) or 4 TELs with 4 missile on each...every AD system has limit on maximum missiles you can have online,they will always set max number...more TELs is always better...I served in PVO...everything is predefined...and there is always at least 6 to 8 times more missile in battery than system can fire at same time,reloading is done on rotation base while engage, one crew reload while other engage....if you fire all missiles in short time...second unit is take over and your go at secondary position any way....,that is how we operated every time.... that is why lowest AD deployment is battery level. So if you need let say more missiles ready to fire,you deploy more batteries or higher level unit. I understand what you are saying.

It's better be 8 missile on 4 tel leek at Syria each time they attack it they use at least 60 missile
by the way here it's stated that the system can control 8 missile but they only put 4 missile there

AD system and missiles is not as AK 47 and magazine..so you just use bigger magazine..missiles are linked with system,they need two way communication,datalinks...have bandwidth limits,processing power limits..electricity limits...weight limits...etc...so military get system with its limitations..BUK battery has 16 online missiles(you can put it on 2 or 4 TELs it is 16 per battery)......but if you need more missiles,you deploy more units...But what I know I just earn pension in military

As I said the system have datalink for 8 missile but only carry 4

And this is point defense system not a system for axample like 3rd of khordad this system have one unit per battery
