the range and altitude of engagement and capabilities are a lot less than standard missile, that would made it repeating the mistake of SeaCat missiles that resulted in Sahand to Sank and Sabalan get heavily damaged. Majid can't protect any ship from enemy aircrafts as it is not designed for that
I am not saying replace SM with Majid. You can add Majid to Mowj without removing SM. Adding Mobin to Mowj won’t save it either. Majid is at least a more easy fix to Mowj’s lack of SHORAD defense.
I have news for you. None of the Mowj ships are surviving against even 1 F-35 or F-22 (if you are concerned about enemy aircraft). They aren’t built for stand alone defense they are supposed to be traveling with a destroyer or with a capable air defense ship that can keep enemy fighters at a distance. Russia lost its flag ship Black Fleet vessel to two anti ship missiles.
It was an ok design to copy back in early 2000’s when Iran Navy needed to add new ships to fleet. But it’s time to move on to heavier and more modern ships like the models they showed off.
