The Pentagon News Agency reported that the United States and eight other countries canceled the 2006 F-35 agreement, and then signed a new agreement that excludes Turkey.
According to ISNA, Turkey is one of the most important suppliers of spare parts for these fighters, and the Pentagon official did not provide further details otherwise.
According to the Daily Sabah, Washington excluded Turkey from the F-35 fighter jet program in 2019.
And arguing that the S-400 air-to-air missile systems purchased by Ankara could be used by Russia.
This is by gaining secret access to confidential details of Lockheed Martin F-35s, which have been ill-treated and deemed incompatible with NATO’s systems.
However, Turkey insists that the S-400 systems do not interfere with NATO systems, and do not pose any threat to the military alliance.
Despite removing Turkey from the program and boycotting the Turkish defense industry in December, the Pentagon said it would continue to rely on Turkish contractors for essential F-35 components.
An observer in the US Congress also reported in May 2020 that the US decision to exclude Turkey from the F-35 program is likely to increase supply chain problems as production increases.
Since then, the $ 398 billion F-35 program has faced countless problems, in particular a shortage of engines.
