Turkey received the first batch of Russia's S-400 missile defence system on Friday in a move expected to raise tensions with the United States, which has repeatedly warned against the purchase.

The delivery at an air base in the Turkish capital Ankara comes after Washington warned this week that there would be "real and negative" consequences if Turkey bought the defence system.

"The delivery of the first shipment of parts of the S-400 long range regional air missile defence system began as of July 12, 2019 to Murted air base in Ankara," Turkey's defence ministry said in a statement.

But Turkish President Recep Tayyip Erdogan said after meeting US counterpart Donald Trump last month that he was confident Ankara would not face sanctions for buying the Russian missile system.

Erdogan told Trump during their meeting on the margins of the G-20 meeting in Japan last month that former US president Barack Obama did not allow Ankara to buy Patriot missiles -- an equivalent of the S-400s.

Trump appeared to be convinced, saying: "You can't do business that way. It's not good."

Game-changer

The first parts of the Russian missile system arrived on two planes at Ankara's Murted air base, Turkish media reported. Turkey's air force changed the name of the base from Akinci to Murted after it was at the centre of a 2016 failed coup.

The delivery comes two days after US ambassador-designate to Turkey, David Satterfield, arrived in Ankara.

But despite the US threats, Turkish officials repeatedly insisted the agreement with Russia was a "done deal".

"We say this each time. This is a done deal. The process continues. We are coordinating this work, whether permission for planes, personnel," Foreign Minister Mevlut Cavusoglu told reporters in Ankara on Friday.

"There are no problems, the process will continue in a healthy manner."

The US and NATO have said that the S-400 is incompatible with equipment used by other members of the alliance.

Nick Heras, of the Center for a New American Security, said the S-400 system would be a "game changer" for Turkey's air defence strategy in region surrounded by actors with well-developed air forces.

"It is no secret that Erdogan is positioning Turkey to be a 'Eurasian' power, which means that Turkey needs to balance its relationship with China and Russia as much as it does with the United States and NATO," he told AFP.

"Turkey is not guaranteed to be in the American camp forever."
