Turkish Armed Forces takes delivery of final 4 CH-47 Chinook helicopters

US Embassy in Turkey has announced the Turkish Armed Forces (TSK) has taken delivery of four US Boeing CH-47F Chinook helicopters at the port Turkey´s western province of İzmir, the embassy said.

With the latest additions, Turkey now has received all 11 of its order of the heavy lift rotary wing aircraft, the embassy said on Twitter.

The delivery of the helicopters arrives amid Washington´s heightened concerns on selling high-end military technology to Turkey.

The United States removed Turkey from the F-35 joint strike fighter programme earlier this month after Ankara procured the Russian S-400 missile defence system. Washington maintains that the S-400 poses a security threat to the F-35 fighter jets and has further threatened Ankara with economic sanctions.

With NATO ally Turkey in both camps, Moscow could obtain F-35 data to improve the accuracy of the S-400 against Western aircraft, according to US officials.
