Iran's Response to the American saber rattling i guess...
Link
I doubt that Iran will be able to purchase enough of these systems and train the crews to a level needed to effectively "ward off" an American air attack but still with these system added to what they have i doubt that they can be destroyed in 3 days.
So, SAMwise (
) Iran has:
S-400: Unknown number, twice the range of Patriots, claimed to be able to intercept "stealth" aircrafts as well as Ballistic and Cruise Missiles
S-300: Unknown number, comparable to Patriot system, newer version are also capable to intercept ballistic missiles (all can intercept aircraft and cruise missiles)
Ghareh About 10 launchers, a (licensed?) copy of the S-200VE "Vega-E"
Pechora-M: Recent (2001?) Russian Modernization of the S-125, A less upgraded version shot down a US F-117 Nighthawk "Stealth Fighter" in Yugoslavia
Sayyad-1: Allegedly a modernized S-75 (Still of Considerable danger if uses S-75M Volga, HQ-2 or comparable level of modernization)
Tor Missile System: At least 29 systems, Low-to-Medium altitude, short range missile system, considered one of the most accurate SAM system around
Buk: successor to the well-regarded Kub, the newest versions are considered quite dangerous
I-Hawk: Unknown Number (30 Launchers?) "Improved version of the original US Hawk system"
Pantsir-S1: About 10, Medium-to-Low altitude, short range, air defense system (12 missiles and 2 auto cannons per system)
Shahab Thaqeb: A Copy of the Chinese FM-80 (itself a copy of the French Crotale) still quite dangerous though.
Kub Flexible and Mobile SAM system, once very successful but now considerably aging.
Tigercat: British missile system (an extremely useless system i might add
)
And 6 Different Types of Shoulder Launched missiles, from pre-Vietnam era soviet designs (functionally obsolete) to the latest Chinese systems that are said to be superior to the newest American FIM-92 Stinger versions.

Vice Chairman of Russia's State Duma Vladimir Zhirinovsky has urged the fast delivery of the magnificent S-400 anti-aircraft missile systems to Iran.
Speaking at the open session of Russia's State Duma on Wednesday, Zhirinovsky stated, "S-400 anti-aircraft missile systems should be delivered as early as possible to enable Iran to defend its air space."
The S-400 is a new generation of anti-aircraft / anti-missile weapon system developed by the Russian Almaz Central Design Bureau.
The S-400 is capable of detecting and destroying targets out to a range of 400km (250 miles), such as aircrafts, cruise missiles and ballistic missiles, including those with a range of 3,500 km.
Sources confirm that the S-400 is capable of detecting and destroying aircraft made with low observable materials such as the American 'stealth' aircraft.
Russia provided Belarus with the same system a short time ago.
The S-400 is so sophisticated and powerful that can change the military balance of a region since it is capable of hitting targets that were previously considered untouchable.
The anti missile system has an unbelievable speed of 4.8 Km per second which is faster than a bullet leaving a Kalashnikov machine gun.
