Seems they have finally a continous radar illumination for AAW capability, and that is really wellcome. But the frigate needs a IFF antenna (usually a small antenna over the search radar) and if possible a news search radar. But that illumination radar gives it a real AAW capability.Sahand updated:

On the other hand the Kamand CIWS is needed of optronic guidance system. And it is much better to have a combined laser telemeter/IR/TV low intensity + Radar. It will give real multitrack signal for targetting radar antiship missile point defence.
Anyway Sahand has growing so much, and it is just a step. Naval construction is showing maturity in Iran, and Turbine Gas and VLS are so near for reaching a truly ocean multirole frigate.
