Syria's Antiaircraft System Most Advanced In World. Syria has gone on a profligate buying spree, spending vast sums on Russian systems, 'considered the cutting edge in aircraft interception technology.' Syria now 'possesses the most crowded antiaircraft system in the world,' with 'more than 200 antiaircraft batteries of different types,' some of which are so new that they have been installed in Syria 'before being introduced into Russian operation service.' While you're digesting that, take a look at the map of Syria: Notice how far away Dayr az-Zawr is from Israel. An F15/16 attack there is not a tiptoe across the border, but a deep, deep penetration of Syrian airspace. And guess what happened with the Russian super-hyper-sophisticated cutting edge antiaircraft missile batteries when that penetration took place on September 6th. Nothing.
El blanko. Silence. The systems didn't even light up, gave no indication whatever of any detection of enemy aircraft invading Syrian airspace, zip, zero, nada.
