Iran to buy China's HQ-9 SAM air defense system
Iran will turn to China instead of Russia to acquire an advanced air defense system after relations between Iran and Russia hit rock bottom, the official Iranian news agency PressTV reported. For years Iran has been trying to purchase the S-300 anti-aircraft missile, which is considered to be one of the most advanced systems available on the market and would dramatically increase Iran's air defense capabilities against any attacks on its nuclear installations.
The S-300 surface-to-air missile system, which can track targets and fire at aircraft 75 miles away, features high jamming immunity making it harder to incapacitate the system electronically, and is able to engage up to 100 targets simultaneously.
Teheran will now turn to China for the HongQi-9/FD-2000 system which combines elements "borrowed" from the Russian S-300 and the American MIM-104 Patriot system, according to the Iranian news agency. Although experts estimate that the Chinese system does not perform as well as the Russian S-300, it still presents an effective addition to bolster the Iranian air defense, which is virtually obsolete against any modern air attack on its vital strategic installations. There is no unclassified information regarding the effectiveness of western countermeasures against the HongQi-9/FD-2000 system, nor against the Russian S-300. There was unconfirmed speculation over possible electronic countermeasures used during the 2007 attack on the alleged Syrian reactor.
