Iranian underground missile bases

According to Iranian authorities, Iranian underground missile bases or silos exist in all provinces and cities of Iran. The bases contain road-mobile Transporter erector launcher trucks, along with other hardware, and due, to the lack of adequate ventilation, could not be as far underground as claimed by Iranian sources. A video from one of the missile sites was released for the first time on 14 October by brigadier general Amir Ali Hajizadeh, commander of Aerospace Force of the Army of the Guardians of the Islamic Revolution. A video report of the missile base was broadcast on Iranian state television on 14 October 2015, just a few days after the news of an Iranian new generation medium-range ballistic missile test was broadcast by the state media of Iran. Amir Ali Hajizadeh stated that: "Iranian missiles of varying ranges are ready to be launched from underground bases once Supreme Leader Ayatollah Ali Khamenei orders to do so," adding that "Iran created missile bases in all the provinces and cities throughout the country at a depth of 500 meters."

Analysis
The release of the footage of the Iranian underground missile bases provided the situation for the lawmakers to show that the July nuclear deal had not weakened the military of Iran and it was a show of strength by Iran in response to the western powers, especially the US, speaking of military options against Iran in spite of the nuclear deal, according to The Guardian. Hajizadeh said that Iran was not seeking for starting a war but "if enemies make a mistake, missile bases will erupt like a volcano from the depth of earth."

According to Tal Inbar a senior Israeli defense expert and head of the Space Research Center at the Fisher Institute for Air and Space Strategic Studies in Herzliya, this missile base "enables the Islamic Republic to store and covertly fire surface-to-surface missiles." He described the underground facility, whose location is unknown, as a "complex system of enormous tunnels". He also added that those bases could be used by Iran for "surprise barrage missile attack".
