Iran "fearful of Attack," Improves Air Defenses
Jerusalem Post: "According to intelligence, Iran has beefed up its air defenses around various nuclear sites as a precaution against a possible pre-emptive strike by US or Israeli forces. The source described the present Iranian air defenses as 'good.' It is known that Iran has deployed Soviet-origin anti-aircraft systems around the 1000-megawatt Bushehr nuclear reactor.
Iran's air defense contains Russian SA-2, SA-5, SA-6 as well as shoulder-launched SA-7 missiles, according to The Military Balance published by the Jaffee Center for Strategic Studies. They also have aged US-made Hawk missiles and have been seeking to purchase the sophisticated S-300P from Russia. "
