This section should be considered as in addition to the previous ‘Fortress Iran’ HERE
S-300 SAM system – CONFIRMED!
There have been consistent reports of Iranian interest in the advanced Russian S-300 SAM system and even rumors of deployment but these have been unsubstantiated for years. As of Jan 2009 it can be confirmed via commercial satellite imagery that Iran does possess S-300 SAMs. The likely model is S-300 PMU-2 although the slightly older PMU-1 is a possibility. The latest S-400 cannot be ruled out but this seems less likely. The likely source of this system remains Russia although China also manufactures S-300 PMU-1 systems.
The S-300 PMU-2 SAM system is among the most feared, and hyped, air-defense weapons in service anywhere and represents a quantum leap for Iranian air defences. Iran reported to have inducted into service a long range SAM system, by implication an indigenous one, earlier this year. Iranian press reports are commonly inaccurate, especially about the origin of technologies (as are the press in most countries!!!) so this may tie in with the S-300 system.
Site analysis
Firstly I’m surprised the site is so close to the nuclear site, which is not a weapons related site. The whole area of Bushehr is heavily defended by multiple I-Hawk and even SA-5 (S-200) SAMs and numerous AAA sites. It is possible that the S-300 site here replaces the other SAMs although because it’s a new site (converted from AAA) we can assume that the other SAM systems are still present. Additionally, the Bushehr location allows the long range S-300 missiles to cover most of the Persian Gulf effectively deterring strike aircraft from taking the ‘straight across’ route from US or the Gulf States, or Israel.
Like the SA-5 in Iranian service, the known S-300 site is noteworthy in that it has fewer launch positions than would be expected for S-300 in service elsewhere. There are two obvious firing pans (as per Iranian S-200) although each is designed for two missile TELs which means up to 16 missiles ‘ready to fire’. Additionally the S-300 is much more mobile than other Iranian systems so additional launchers could easily be set up nearby and networked in. There is only one elevated radar ramp, presumably for the fire-control radar. The radar in this case looks to me more like the ‘Cheeseboard’ system rather than a ‘Flap lid’ series, hence my belief that it is S-300 PMU-2 not PMU-1. Additionally, the ‘Big bird’ surveillance radar effectively rules out older version of the S-300, although not conclusively.
Alternative hypothesis
Alternatively, the fresh satellite images are not Russian supplied S-300 but an Iranian clone/cousin of the system. That Iran is developing an indigenous “S-300” has been reported, and possibly with a lot of Russian assistance although we should strictly treat it as a rumor. The system would be similar in capability to the S-300 and share many technologies but may be quite different in end product – akin to the Chinese HQ-9 program. The below illustration shows a ‘what-if’ of an “Iranianized” S-300 system:
Iranian garage-build CIWS
Iran uses a large number of AAA particular to defend static high-value installations, such as nuclear sites. Further, Iran has purchased much more advanced SA-15 and Pantsyr S-1E short-range SAM systems. However, these are expensive and not easily reverse engineered, so Iran has also pursued numerous indigenous AAA projects. The main ones, and most successful it seems, have been simply reverse engineering the ubiquitous Russian Zu-23-2 23mm gun and the Swiss 35mm Oerlikon ‘Sky guard’ system. However, these offer little defense against cruise missiles and PGMs. Perhaps with this in mind Iran has pursued several lines of development to improve accuracy, or volume of fire.
Fully automating the 100mm AAA
This project has only recently been unveiled. Essentially the obsolete crew-intensive KS-1 gun has been modernized so that it has fully autonomous transverse, elevation and firing. Coupled with a fire control system this allows much more accurate fire (and by implication greater effective range) than with a human crew. It also seems possible that a guided shell is used, although this is unconfirmed. If deployed in numbers this system will greatly enhance Iranian SHORAD.
Super-size Zu-23
The Zu-23-2 is a pretty decent AAA, but Iranian engineers have come up with a fiendishly cool idea: Why not bolt three Zu-23s together, so that you have three times the volume of fire? The Zu-23-6 uses a S-60 57mm AAA gun carriage, and has an assumed cyclic rate of fire of 6,000 rds per minute. That’s more than the Phalanx CIWS!
Another project involving improving the Zu-23 is to make it fully autonomous, although it’s not clear if this has progressed beyond trials.
There is also an Zu-23 with MANPAD missiles attached although it’s not clear if this has entered service.
Increase in Iranian air defence sites from 2003 – 2006 and beyond
Iran greatly increased the number of AAA sites from 2003 onwards, especially around nuclear sites. In part this was because once Iran’s nuclear programs were revealed, there was no longer a need for ‘low key’ installations. The ‘historic imagery’ feature on Google Earth lets compare satellite imagery across time:
Imagery of Natanz nuclear site is particularly interesting as it shows the construction of the ‘secret’ underground complex to house the nuclear centrifuges. This was spotted by Western observers and the nature of the site is now well documented.
I previously posted an analysis of the air defences around Natanz, identifying a mix of 23mm and 35mm AAA. This recent internet-sourced photo confirms the presence of the latter type. Always noce when analysis of satellite imagery is confirmed!
As well as AAA sites, the SAM sites covering the area are also quite recent:
Elsewhere in Iran we see a similar pattern, with many air defence positions being recently built:
