US warplanes could fly past Russian S-400s if the frequencies of the air defense systems obtained by the US army in Syria's Khmeimim air base, are successfully deciphered.
"The US army has obtained the frequencies of the Russian S-400 anti-air defense systems stationed in Syria. The US military have, however, not been able to decipher the codes yet," Russia's Free News reported, citing pilot Yuri Sytnik, a member of the Senior Officers Council of the Officers of Russia organization, as saying.
“The US is taking note of our frequencies, taking note of our systems which are starting to be deployed against it (the US’s Boeing P-8 Poseidon aircraft). Now they need to decipher our S-400 systems that are there. That’s why they’re being driven back. It’s a normal practice. They are testing our ability to repel. Reconnaissance is being done. This aircraft is an entire laboratory. There, a crew of 20, in a special cubicle, monitor the radio-electronics and collect footage,” said Sytnik.
The codes were intercepted by the US military using reconnaissance aircraft flying over Russia’s Khmeimim air base. The US Air Force can neutralize the threats posed by S-400s through deciphering the obtained codes. This is achieved through creation of virtual targets and hampering identification of aircraft.
US reconnaissance aircraft have earlier flown along the coast of Crimea, but have failed to identify the frequencies used by the Russian anti-air systems in the region. These frequencies differ from those used by the S-400 systems stationed in Syria, Free News report said.
