Iran has designed and tested successfully an air defense system that has the same capability as the Russian-made S-300 missile system, the local satellite Press TV reported on Thursday.

"We have developed the system by upgrading systems like S-200 and we have tested it successfully using all our potential and experience in the Islamic Revolution Guards Corps (IRGC), the Army and the Defense Ministry," Brigadier General Mohammad Hassan Mansourian was quoted as saying.

This comes as Russia cancelled a deal concerning the sale of its S-300 system to Iran, Mansourian told Press TV on Wednesday.

He said that the details of Iran's long-range missile defense system will be unveiled soon, according to Press TV.

Iran inked a deal with Russia to purchase the S-300 weaponry systems in 2007, however, Russia scrapped plans to deliver the air defense missile systems to Iran as it falls under the UN sanctions, Russian Chief of General Staff Nikolai Makarov said in September.

The S-300 is an advanced mobile missile system which can shoot down aircraft and cruise missiles from up to 150 km away.
