Iran has domestically designed and built a long-range air defence system with the same capability as the Russian-made S-300 system.

Iranian Brigadier General Mohammad Hassan Mansourian said the country has developed the new system by upgrading S-200 missiles and the details of the missile system would be unveiled soon.

“We have tested it successfully using all our potential and experience in the Islamic Revolution Guards Corps (IRGC), the army and the Defense Ministry,” he told Press TV.

Iran built the missile system following the cancellation of an $800m deal signed with Russia in 2005 involving the sale of its S-300 system in September 2010.

The S-300 air defence system is an advanced mobile system capable of shooting down aircraft and cruise missiles from a distance of 150km.
