If you think 3rd Khordad is based on Buk... then you dont know what you are talking about..... 3rd Khordad is based on Standard missiles, thats why the lunchers have 3 missiles, rather than 4 o Buks.
There are also 2 missiles with exactlly same design as BUK-M1/M2 missiles but all 3 versions RAAD2,Tabas and 3th of khordad ,even share similar look,have very different radars...I tought also it is based on BUK-M2E till I didn't saw radars...It share many things with BUK-M2,that is truth...it has same battery design and deployment ,use as BUK and TOR Kasta 2e as search and acquisition radar but it is much more than BUK...and all 3 versions outperform BUK counterparts...So,they probably analyzed BUK M1/M2 but Tabas and 3th of Khordad radar antennas are completely different.... As I could see when comparing Iranian new radars and AD systems, they share similarities with Russia and Chinese counterparts but seems Iran don't want end up in situation where any 3th party has knowledge on their AD assets so they don't simple copy some technology, everything we saw is heavily modified and make it different than counterparts.
Should I said that medium range AD systems are main line of defense against fighter aircrafts,even long range system engage fighter aircrafts at medium ranges...so it is very important to have combat proven system. This target was not easy,MQ-4C is most advanced drone that exist... They call it flying data hub,and it has some stealth capability... But what make it even more harder to target is fact that it try to hide above air trafficking,and despite that they identity target successfully and downed it with one missile(even for slow drone one is only needed)...I saw news minute after they released it and they immediately say it is RQ-4(which is base for MQ-4).
What I saw about this MQ-4 situation, BUK wouldn't be able to reach it probably ...Russian news outlets at first said it was s-300 but latter we found out it was 3 th of khordad which was what I thought ,I was sure it is SU-22 aircraft or 3th of khordad, simple because we know what IRGC operate and those two are logical options for such high altitude... I must say,I'm surprised with efficiency of 3th of khordad and it is not because it is Iranian ,simple because it is very new and it is not simple copy of some already proved SAM...
it's a new, more technological missile with a new function. Sorry to tell you but it's like that ... Do you have any other information about it? And I know it's missile of S-200 HELLO!
No..no info except what I already said about Iran S-200 upgrade and modifications. That is,they solved main flaw of S-200 that makes it very limited against fighter aircrafts and that is huge minimal range.Iran demonstrated S-200 shut down drone in visual range...In reality you will never use such expensive missile and strategic SAM vs drone in close range...they just wanted to demonstrate it is capable to target it,and this is not first time Iran showed modified S-200 missile
.S-200 missile is one of the fastest missiles ever built for SAM and system is pretty capable but it was designed in different time for different deployment but still even today pretty good even without any upgrade. This is not first time Iran showed domestic modified S-200 missile....any way since you have to defend many strategic static objects ,S-200 and most other static SAM are deployed around or inside these strategic objects so you defend object and SAM with same SHORAD and medium range systems...
