The article first said that Russia has made a final decision not to sell Iran S-300 air defense missile systems, Russia and Iran also do some business, and quickly returned to Iran for the purchase of an advance payment of S-300 166800000 dollars, the deal valued at more than 10 billion U.S. dollars, the Russian defense industry for the final result is not satisfied. But for Russia, there is also "flash" side. To withstand the pressure of the West after three years, especially the pressure from Israel, Russia canceled the deal, the Western hope that modern weapons from Iran, then made a deal with Russia, that is, to Russia through a joint production agreement Western defense technology transfer, in return, Russia does not sell high-tech weapons to Iran; present, the issue of arms sales to Syria, Israel is working with the Russian debate, Israel believes that Syria is Iran's intermediary, advanced weapons are used as buyers, and these weapons will eventually become a foregone conclusion and Iran, Russia opposed the restrictions, the Israeli threat to Syria's cooperation if Russia does not cut off, to party to terminate the cooperation with Russia.

The article says the U.S. media, at the same time, the loss of S-300 as a response to the procurement, Iran announced that it has continued to design their own performance with the S-300 similar to the system. Today, Iran regularly announced those who designed and built a 30-year trade embargo and can not buy modern weapons from abroad, very few of these weapons out to show that, despite some appearances to the form of a prototype weapon. At the same time, S-300 or similar system has not yet delivered to Iran, as Western nations have told Russia and China, Iran, if armed with modern weapons, will face serious "consequences."

U.S. media went on to say, but "Iran's S-300" may be more likely to (hand), because last year Iran had sought to purchase Chinese-made HQ-9 system. Article speculated that it is believed that China had supplied Iran with some technology, but it did not deliver the weapons, to avoid the western countries with less conflict. China has a number of countries overseas HQ-9 system, that is, FD-2000, expressed dissatisfaction with the Russian people, they think some of the technical S-300 HQ-9 used in the above, Russia also warning China not to foreign sales with "plagiarism" Russian technology weapons, but apparently little effect, and then guess the U.S. media, in this case, China may be as to the previous, FD-2000 quietly sell Iran the technology to make their own production, as models name is as you wish.

U.S. media said 10 years ago, China began in the Army and Navy ships with HQ-9, after 10 years of development, it is believed that similar products of China from the United States and Russia benefit from the data obtained, HQ-9 similar in the U.S. "Patriot", it is more like the radar used Russian-made S-300 from the radar used evolved. HQ-9 missile has a maximum range of about 100 km, playing weight of 1.3 tons, the use of the passive seeker, the Army uses mostly mobile type, the Army HQ-9 Brigade is a brigade headquarters (a command vehicle and 4 Ministry of Communications and maintenance trucks for the composition) and 6 missile battalion (a missile control vehicles, a goal of guided radar vehicle, a search radar, missile launch vehicles and eight cars) component.

U.S. media concluded that, S-300 and HQ-9 have not tested in actual combat, Russia (Soviet Union) early in the design of the air defense system's poor performance in actual combat, even for use in Egypt in 1973, SA-6 missiles, at first also allows Israel surprised, soon to be restrained, did not stop Israel (fighter) of the cross.
