Iran has deployed its Russian-made S-300 surface-to-air missile system around an underground uranium enrichment facility in Fordow, 125 km southwest of Tehran, Iranian state television has reported. Commenting on the deployment, Iranian experts have suggested that this is more evidence about the depth of the Russian-Iranian strategic partnership.

Speaking to�state television on�Sunday, Farzad Esmaili, the commander of�Iran's Air Defense Force, explained that "our main priority is to�protect Iran's nuclear facilities under�any circumstances." While the commander did not clarify whether the S-300s at�Fordow were already operational, Esmaili did say that "today, Iranian skies are among�the most secure in�the Middle East." The commander's remarks were accompanied by�state television footage showing the recently purchased S-300 missile systems being transported and deployed in�the area around�Fordow.

Commenting on�the deployment, Sajjad Tayeri, an expert in�Iranian-Russian relations, suggested that the news serves as�another indication that cooperation between�Russia and Iran has reached a strategic stage. Speaking to�Sputnik Persian, Tayeri recalled that the supply of�the S-300 had long been seen as�a problem area in�the deepening of�Russian-Iranian relations, with�Russia promising to�supply Tehran with�five S-300 systems in�2007, before�suspending the contract in�2010, citing a UN Security Council resolution which placed an arms embargo on�Tehran.

In April 2015, shortly after�Iran and the P5+1 group of�international negotiators reached an agreement to�remove all sanctions against�Tehran in�exchange for�the country's pledge on�the peaceful purposes of�its nuclear program, Russian President Vladimir Putin lifted the S-300 delivery ban. The first batch of�S-300s was delivered to�the country earlier this year. "Today," Tayeri noted, "we see that after�the signing of�the [nuclear deal], when various countries' trust in�Iran has been restored, the long-standing friendship which has always existed between�Russia and Iran has strengthened even more." The analyst suggested that Moscow and Tehran's cooperation in�the anti-terrorist operation in�Syria, along�with the recent negotiations on�the legal status of�the Caspian Sea, have only further increased the level of�mutual trust and collaboration between�the two countries. "The level of�cooperation between�our countries is growing, and is becoming more effective."

Asked to�comment on�the likely implications of�the deployment of�S-300 around�Fordow, the analyst pointed to�Sunday's statement by�Iranian Supreme Leader Ayatollah Khamenei, who emphasized that the S-300 is a purely defensive system, not an offensive one.� "Iran," Tayeri added, "has never created any plans for�aggression or invasion of�other countries; it does not have such plans and never will." According to�the expert, "the Russian S-300 and its Iranian made analogs are intended for�the defense of�our territory � of�key industrial objects." Noting that Tehran still has many reasons not to�trust Washington, including in�its fulfilment of�its side of�Iranian nuclear agreement, the analyst emphasized that "as far as�cooperation between�Russia and Iran is concerned, it has, on�the contrary, been greatly strengthened and is already at�the strategic level. It's for�this reason that the Russian S-300 systems were deployed around�our country' nuclear and strategic military facilities."

Fordow's underground uranium enrichment facility, revealed to�the world in�2009, has not engaged in�uranium enrichment since�January 2016, when the Iranian nuclear deal's provisions came into�effect. The facility is built about�90 meters under�a mountain. Iranian officials have since�said that the decision to�build the facility deep underground in�a fortified position was made due to�repeated threats by�Israel to�attack such facilities. Tel Aviv carried out�a surprise airstrike on�an Iraqi nuclear reactor in�1981. Iran showcased its own new air defense system, the Bavar-373, at�a military expo last week. The system's development has prompted speculation that it was designed as�Iran's answer to�the S-300.
