PREVIEW

The ''Sevom Khordad'' Aerial defense system is displayed by the Islamic Revolutionary Guard Corps (IRGC) during an annual military parade marking the anniversary of the beginning of the war against Iran by former Iraqi Dictator Saddam Hussein 44 years ago, in front of the shrine of the late Revolutionary founder Ayatollah Khomeini, southern Tehran. The Sevom Khordad, or 3rd Khordad, is an Iranian road-mobile medium-range air defense missile system unveiled on 11 May 2014. It is considered an upgraded version of the Ra'ad air defense system and somewhat superior to the other version of Ra'ad, Tabas (air defense system). However, it is more similar to the Ra'ad than the Tabas. Its operational capabilities were confirmed when it shot down an American Northrop Grumman RQ-4 Global Hawk near the Strait of Hormuz. It is named after Khorramshahr's Liberation, which occurred on the 3rd Khordad on the Persian Calendar.
