Turkey clears way to test Russian S-400 defence system this week
ANKARA, Oct 15 (Reuters) - Turkey has issued notices restricting air space and waters off its Black Sea coast to allow firing tests apparently on Friday involving its Russian-made S-400 missile defence units, a week after they were transported to the area.
While Turkey already tested the surface-to-air weapons last year, further exercises could stoke tensions with NATO ally the United States, which sharply opposed the purchase from Moscow on grounds the S-400s compromise NATO defence systems.
Washington reacted last year by expelling Turkey from its F-35 jet programme and has threatened sanctions. The lira has remained near all-time lows since videos in local press last week showed the S-400s being hauled north from near Ankara.
Turkey's air space notice, or NOTAM, restricts an area near the coastal city of Sinop for a radar test and possibly live-fire for six hours on Oct. 16. It advised aircraft to avoid the area to a height of 200,000 feet (61,000 metres).
Earlier this week, Turkey issued a maritime notice for shooting training and two others for military training. The so-called NAVTEX notices said shooting training would be held Oct. 16-17.
The S-400 surface-to-air defence system is one of the most advanced in the world with a medium to long-range radar that can spot and track incoming aircraft, directing a barrage of missiles at their targets to a range of 400 km (249 miles).
Turkey signed the S-400 deal with Russia in 2017. Deliveries of the first four missile batteries, worth $2.5 billion, began in July last year. Ankara has carried out radar tests previously but the shooting test will be a first.
Last week - after videos of the S-400 videos emerged and reports of the planned tests circulated - two U.S. senators called again for President Donald Trump's administration to impose sanctions on Turkey.
