Russia Responds Possible US Attacks in Syria with S300, S400 Air-Defense Systems

Russian Defense Ministry has announced that country's most advanced air-defense systems are ready to give a crushing response to any possible assault by the US on Russain forces in Syria.

"Russia will use its S300 and S400 anti-aircraft systems to target any attack on its naval base in Tartus and its airbase in Humeimim," the ministry said, adding, "The S300 and S400 air-defense missile shields can easily intercept and target any advanced model of stealth planes too;" FNA reported.

The S-300 system can be used to defend against aircraft and cruise missiles. Meantime, it can intercept ballistic missiles.

As tensions between Washington and Moscow flare, the Russian military is warning the United States that it had the ability to target stealth aircraft such as the Lockheed Martin F-22 Raptor, F-35 Joint Strike Fighter and Northrop Grumman B-2 Spirit that might be operating over Syria with the Almaz-Antey S-400 (NATO: SA-21 Growler) and the recently arrived S-300V4 (NATO: SA-23 Gladiator) air and missile defense systems.

However, Western defense officials and analysts are skeptical and note that both the F-22 and the F-35 were specifically designed to counter those Russian-developed weapons, the National Interest reported.

"Russian S-300, S-400 air defense systems deployed in Syria's Humeimim and Tartus have combat ranges that may surprise any unidentified airborne targets,” Russian Defense Ministry spokesman Major General Igor Konashenkov told the Russian state media outlet Sputnik.

“Operators of Russian air defense systems won't have time to identify the origin of airstrikes, and the response will be immediate. Any illusions about ‘invisible’ jets will inevitably be crushed by disappointing reality.”

However, while Moscow makes bold claims about the counter-stealth capabilities of their S-400 and S-300V4 air defense systems, the fact remains that even if Russian low-frequency search and acquisitions radars can detect and track tactical fighter-sized stealth aircraft such as the F-22 or F-35, fire control radars operating in C, X and Ku bands cannot paint low observable (LO) jets except at very close ranges. Stealth is not—and never has been—invisibility, but it does offer greatly delayed detection so that a fighter or bomber can engage a target and leave before the enemy has time to react.

Tactical fighter-sized stealth aircraft must be optimized to defeat higher-frequency bands such the C, X and Ku bands—that’s just a simple matter of physics. There is a ‘step change’ in an LO aircraft’s signature once the frequency wavelength exceeds a certain threshold and causes a resonant effect. Typically, that resonance occurs when a feature on an aircraft—such as a tail-fin or similar— is less than eight times the size of a particular frequency wavelength. Fighter-sized stealth aircraft that do not have the size or weight allowances for two feet or more of radar absorbent material coatings on every surface are forced to make trades as to which frequency bands they are optimized for.

That means that radars operating at a lower frequency band such as parts of the S or L band are able to detect and track certain stealth aircraft. But ultimately, to counter lower frequency radars, a larger flying-wing stealth aircraft design like the Northrop Grumman B-2 Spirit or the B-21 Raider—which lacks many of the features that cause a resonance effect—is a necessity. But at the UHF and VHF band wavelengths, designers are not trying to make the aircraft invisible—rather engineers hope to create a radar cross-section that will blend in with the background noise that is inherent to low-frequency radars.

Low frequency radars can be used to cue fire control radars however. Additionally, some US adversaries have started to make an effort to develop targeting radars that operate at lower frequencies. However, those lower frequency fire-control radars exist only in theory—and are a long way off from being fielded.

“Stealth is ‘delayed detection’ and that delay is getting shorter. SAM (Surface-to-Air Missile) radars are shifting their frequencies into lower frequency bands where U.S. stealth is less effective,” said Mark Gammon, Boeing’s F/A-18E/F and EA-18G program manager for advanced capabilities, had told me some time ago. “Early warning radars are in the VHF spectrum where stealth has limited if any capability. These radars are networked into the SAM radars giving the SAM radars cued search.”

But low-frequency radars do not themselves provide a “weapons quality” track that is needed to guide a missile onto a target. There are various techniques that have been proposed to use low frequency radars for such purposes, but none of those are likely to prove viable. US Air Force Col. Michael Pietrucha had described one possible approach to me to accomplish such a feat in an article I wrote for Aviation Week & Space Technology a few years ago. However, U.S. Air Force officials were dismissive of the technique. “Just because something is technically possible doesn't make it tactically feasible,” one Air Force official with extensive stealth aircraft experience explained.

Meanwhile, operational Raptor pilots tell me “it would be really classified to discuss specific SAM counter tactics,” however, the F-22 is more than capable of defeating any of the current Russian surface-to-air missile systems that are currently or projected to be fielded. Hopefully, we will not have to find out the how effective the Raptor truly is during a shooting war over Syria—since conflicts can rapidly escalate out of control, as history loves to teach us over and over again .
Despite the theoretical bases put forward by the National Interest report, the Russian air defense unit deployed in Humeimim and Tartus have managed to identify several radar evading aircraft of the US army from a long range in practice.
Last week, a US spy plane was spotted flying off the coasts of Syria near the Russian base in Tartus while another one was picked up by radars as it was conducting reconnaissance operations over the Russian fleet near Crimea in the black sea, western websites said.

The western websites that monitor military movements across the globe reported that a US spy plane of RC135W with tail number 62-4138 left Souda Bai Airbase in the Greek Crete Island and launched reconnaissance operation over the Russian navy fleet Southwest of Crimea's coast.

The website added that another US P-8A spy plane with tail number 169958 also left Sigonella Airbase in Sicily on a reconnaissance mission over the Russian warships and base in Eastern Mediterranean Sea and Southern Cyprus.
The US plane's spy operation near Syria's waters lasted for around half an hour before it moved towards Lebanon.

Also last month, a US P-8A Poseidon spy plane was spotted again flying off the coast of Lebanon and Syria, near Tartus.

The US Navy reconnaissance plane was spotted at the time flying a few kilometers away from Russia’s Humeimim airbase in Syria.

The P-8A Poseidon aircraft flew close to Syria’s Mediterranean coast where Russia’s naval task force operates. It was the fourth time that a US spy plane was spotted near the Russian base in Humeimim.

Humeimim military airport, Southeast of the city of Lattakia, is Russia’s strategic center of operations against the ISIL and other terrorist groups.

According to reports, the P-8A Poseidon aircraft, designed and built for anti-submarine warfare and intelligence gathering, took off from the Mediterranean island of Sigonella in Sicily. The aircraft, with tail number 168761 then flew over Syria’s coast for one and a half hours in close proximity to the Russian airbase and logistics facility located at Tartus port, South of Lattakia.

Observers believe that the US spy planes have recently increased their flights over Syria to gather intelligence on the Syrian army and the Russian forces' moves in the region.

According to reports, on August 30, September 2 and September 17, the P-8A Poseidon spy plane was also spotted flying toward the vicinity of the Russian airbase.
