“Delivery of S-400 Long Range Air and Missile Defense Systems resumed today. The fourth Russian plane carrying S-400 parts landed at Murted Airport outside Ankara,” the ministry said, sharing a picture of the Russian aircraft.
Turkey received the first three shipments of S-400 components on Friday, defying threats of sanctions from the United States.
It remains unclear when the S-400 surface-to-air system will be installed and operational.
Turkey would be the first NATO member to operate the advanced Russian system and the purchase has become a bone of contention with Washington.
The US has already started removing Turkey from the F-35 fighter plane programme. The training of Turkish pilots in the US is set to halt at the end of this month.
