Instead of building these so called smart weapons it would be smarter if the built their A bomb, the only way to keep the USA at bay. In a battle situation with USA these bombs will be no match as the US / Israeli air dominance will ensure not one Iranian Plane takes of to deliver the smart bombs. I think its more for local in house propoganda. Out of curiosity what kind of guidance will it have.
Cannot have GPS as the Americans control it.
Cannot be laser guided as they would require someone or an aircraft to paint the target, which the Americans will not allow.
