This is Significant………

It turns out that the aircraft that Russia is sending to Syria are not Su-27s or MiG-31s. They are top of the line Su-30SM multi-role fighters:

The Institute for the Study of War had spotted four Russian fighter jets at Al Assad International Airport in Damascus. The Kremlin may have sent air-to-air missiles to Syria along with the aircraft, the D.C.-based think tank added.

But Washington area consultant and War Is Boring contributor Chris Biggers pointed out on the blog Offiziere that ISW had misidentified the jets. As it turns out, Russia sent its maneuverable and deadly Su-30SM multi-role jets.

Recent satellite imagery acquired by Airbus of al-Assad International airport in Syria shows four Su-30SM aircraft, not four SU-27 Flanker as originally reported by the Institute for [the] Study of War. The aircraft are easily mistaken for the SU-27 due to the modern variant’s use of the same airframe. The only predominant identifier on satellite imagery separating these aircraft from the earlier model is the canards positioned forward on the fuselage which assist with the aircraft’s thrust vectoring capability.

Located on the north side of the runway at Latakia, the Su-30SM multi-role fighters are one of Russia’s more advanced 4+ generation aircraft, often compared to the U.S. Air Force F-15E Strike Eagle. This variant is equipped with a passive electronically scanned array (PESA) BARS radar, fly-by-wire flight controls, modern ECM as well as thrust vectoring, making this a highly maneuverable and capable fighter.

In March 2012, Russia hired the Irkut Corporation to build a total of 60 Su-30SM fighters. While the new model was the first for the Kremlin’s air arms to feature the small canard positioned behind the cockpit, Irkut had already sold similar MKI and MKM versions to India and Malaysia, respectively.

The reason that this is important is because of the whole "Multi Role" thing.

The Su-30SM is not as well suited for the interception role as the MiG-31, top speed and ceiling are lower, but it can carry a much wider range of munitions, including the KH-58 anti-radiation missile, which has the capability to attack surface to air missile installations at ranges greater than 200 km, which could suppress NATO SAMs in Turkey that have largely prevented the Syrian Air Force from operating in the north of the country.

Syria is a complete clusterf%$#, (When the Assad regime is the best alternative, you know that you have completely screwed the pooch) , and now we are seeing increased Russian involvement in the conflict.

It's a mess, and it's getting scary.
