What disturbs Washington from Turkey's purchase of the S-400?

The Washington Post says the main reason for Washington's objection to Turkey's acquisition of the Russian S-400 missile defense system is that Turkey may have American F-35 fighter jets. Having the most sophisticated aircraft with these missiles might enable Russians to acquire " F35 ", then learn how to target their weaknesses.

US officials have expressed concern that if the two systems - the S-400 and the F-35 - are in close proximity, the Russians will receive more information about F-35 capabilities, which will help them develop Their ability to locate the US fighter on the radar.

Fear on the "F-35"
The US Defense Secretary said in May that the S-400 was designed to shoot down fighters like the F-35, and it was inconceivable that Russia would not gain access to secret information about the fighter.

Pentagon spokesman Lieutenant Colonel Mike Andrew said last week that Turkey would not be allowed to get the S-400 and F-35 systems together.

The dispute has made America uncomfortable, as it is keen to prevent Russia from gaining access to its sophisticated fighter, but at the same time it relies heavily on Turkey as an important partner in the region for strategically setting its common border with Iraq, Iran and Syria.

"The S-400 is a danger to the F-35," he said, saying it was not a threat at the moment. Previous estimates indicate that the S-400 radar systems were able to locate the F-35, If it is within 20 miles, but the F-35 carries air-to-ground missiles capable of destroying the S-400 over 40 miles.

What can Washington do?
On what Washington can do now, the newspaper said US officials had previously threatened to cancel the sale of F-35 fighter jets to Turkey and impose economic sanctions against it.

In April, the Pentagon announced that Turkey would stop participating in a pilot training program for F-35s until Ankara agreed to cancel the purchase of the S-400.

But at the G20 meeting in Japan last month, US President Donald Trump blamed the administration of former US President Barack Obama for the dispute between Washington and Ankara, saying it was not the fault of Turkish President Recep Tayyip Erdogan, adding that he did not think his country would impose economic sanctions on Turkey because of This subject.

Erdogan said Turkey had the S-400 system in line with its sovereign right to defend itself, and urged Washington not to let Ankara buy the Russian defense system, causing the deterioration of the strong relations between them, noting that the loss of a country like Turkey is not easy.
