Iran has designed an air defense system that has the same capability as the Russian-made S-300 system, a top military official says.
"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 Corpse (IRGC), the Army and the Defense Ministry," Brigadier General Mohammad Hassan Mansourian told Press TV on Wednesday.
This comes as Russia cancelled a deal involving the sale of its S-300 system to Iran in September, the general added.
General Mansourian noted that the details of Iran's long-range missile defense system will be unveiled soon.
On November 3, Iranian President Mahmoud Ahmadinejad criticized Russia for its "one-sided and illegal" cancelation of the military deal.
"This agreement must be implemented. If they (Russians) refrain from fulfilling their commitment, the Iranian nation will ask for its rights and damage inflicted to it," President Ahmadinejad said.
Based on an $800 million contract signed in 2005, Russia agreed to provide Iran with at least five S-300 systems.
Russian President Dmitry Medvedev issued a decree in September to prohibit the delivery of the S-300 to the Islamic Republic under the pretext of a US-engineered sanctions resolution imposed against Iran over its nuclear program.
Iran criticized Russia, arguing that Resolution1929 does not justify Moscow's refusal to commit to the deal as it does not specifically ban the delivery of the defensive missiles to Tehran.
