S-400/S-500 can engage iskander.Which "COMMON" air defense system can shoot down Iskander? You just seem to have mentioned an outlier, which doesnt prove a real point.
Yes Iranian version was produced after second development of PMU2 or protracted development of PMU2 if vesion when Russians decided to make PMU 2 ,PMU3(pmu3 was later renamed to S400 for marketing purpose)and future S500 and S350 to share as much as it could technology and make them more compatibile,also Iranian version include some ,on Iran request,custom futures so Nato codename is SA-20C.The Iranian S-300 is an improved version of the PMU-2. We can say that it is an S-300 PMU-3. It is clear that Iran is working on it to improve it so it is certain that its performance is improved.
I think there is a passive planar array radar that is truck mounted that might accompany the system. It's mounted onto a pickup just like the rest of the system and should easily integrate with it. I think it was actually shown as a third truck in the parade today but I have to go back.Laser guided sams can be used by itself against smaller low flying drones which have low heat signatures. Also they would be effective against cruise missiles if its E/O thermal imaging system can detect cruise missiles from sufficient distance.
If qued by another radar vehicle they can engage cruise missiles more effectively. Getting initial target data from a radar they can also engage targets like glide bombs which dont have engine-very low ir signature. Radar vehicle/ sam system would not need to track each and every target and guide missiles against them by delegating such vehicles for specific targets like low flying drones or cms reducing their burden.
I think the radar we were both talking about is in the picture you posted just behind the main vehicle. Also, I think the other truck carrying misagh might also be integrated into this system.
It looks like this systems is intended to have a loadout of 4 missiles,rather than just the 2 that we see here.
Its actually not a bad looking system,you`ve got what looks to be a rotating optronic scanner and 4 missiles,with possibly either optronic or imaging infra-red seekers.Its also likely to be able to be plugged into a separate radar for longer range search as well,like the small light vehicle mounted anti drone radar that was unveiled a few months back.
both have tested against ballistic missile......i remember that the commander of the air defence system said to the press reporters that even russia doesn't define this type of mission for s-300(he meant against ballistic missile)........I may be wrong but I think that was Bavar Test not S-300
This is not a new system more like refurbished. I have seen it 10+ years at military parades!
