Its the closest the world has reached a World war III level since 1945.

Russia has deployed several A-50U airborne early warning and control planes in a bid to systematically warn the United States that its ready to shoot down all of its misslies in Syria if launched targeting the Assad Government.

The sophiscated AWAC Planes could help Russian missile defenses with targeting acquisition, as well as disrupt the US' missile targeting.

The A-50U is a "giant flying data processing center" used to detect and track "a number of aerial (fighter jets, bombers, ballistic and cruise missiles), ground (tank columns) and surface (above-water vessels) targets," Sputnik, another Russian state-owned media outlet, previously reported.

It also informs "command centers about the developments in the air and sea, and directing fighter and strike aviation."

The US appears on the verge of striking Syria after the government allegedly carried out a gas attack over the weekend.

But Russia has vowed to shoot down any US missiles with its air defenses, including the S-400, its most advanced missile defense system.

The "Russian military may use a limited response – using airborne electronic warfare equipment to harass the American ships, messing up their target acquisition, geolocation or even AEGIS anti-aircraft systems,".
