The US Senate Armed Forces Committee has passed its version of the Nation Defence Authorisation Act, a $716 billion bill.
An amendment added by Democratic Senator Jeanne Shaheen and Republican Senator Thom Tillis could potentially see the removal of Turkey from the F-35 programme, over its detention of a US citizen.
This would effectively bar Turkey from purchasing the F-35 Joint Strike Fighter, if passed into law.
The amendment was also partially motivated by the Turkish purchase of Russian S-400 surface to air defence batteries and makes specific mention that this could result in sanctions on Turkey.
There has been concerns on supplying Turkey with the Lockheed Martin’s latest stealth fighter, even though they are a partner nation of the programme and are planning to purchase 100 of the planes.
The NDAA is yet to become law and the Senate is still to vote on their version of the bill which may remove this amendment.
