Turkey defies US as Russian S-400 missile defence arrives

Agency News

Ankara, Jul 12 : Turkey has received the first part of a Russian S-400 missile defence system despite opposition from the US.

The shipment arrived in an airbase in the capital Ankara on Friday, the Turkish defence ministry said, according to a BBC News report on Friday.

The move will anger the US, which has warned that Turkey cannot have both the S-400 anti-aircraft defence system and US F-35 fighter jets.

Turkey and the US are Nato allies -- but Turkey has also been establishing closer links with Russia.Turkey has signed up to buying 100 US F-35s, and has invested heavily in the F-35 programme.

However, US defence officials have said they do not want the F-35 jets to be near S-400 systems -- because they fear Russian technicians will be able to access the F-35's vulnerabilities.

How does the S-400 work?
* Long-range surveillance radar tracks objects and relays information to command vehicle, which assesses potential targets
* Target is identified and command vehicle orders missile launch
* Launch data are sent to the best placed launch vehicle and it releases surface-to-air missiles
* Engagement radar helps guide missiles towards target
