According to a U.S. assessment, the strikes crippled Iran's missile production capability, estimating it would take at least a year for Iran to rebuild the destroyed components necessary to resume production.[1] U.S. and Israeli officials said that most of Iran's air defense network, including nearly all of its advanced S-300 systems, were destroyed, paving the way for potential future Israeli strikes

hmm, wonder where those attacks took place because there were almost 0 reports of any major explosions anywhere in Iran, something that is expected when a target such as S-300 missiles are hit (secondary explosions are usually much larger than initial one when AD missiles explode).
