"Iran has a very backwards military with almost no air force and no serious navy power at all." Iran has been developing a variety of land-based anti-ship ballistic and cruise missiles. Given that their naval interests are limited to the Persian Gulf, the Strait of Hormuz, and the Sea of Oman (and the Caspian), that's probably enough naval power. Your air strikes are going to have to track down mobile launchers.
