Trump Administration Reaffirms Opposition to Turkey Rejoining F-35 Program
The US State Department reaffirmed that Turkey's continued possession of the Russian S-400 missile system blocks its participation in the F-35 program under US law.
- On August 20, 2025, the U.S. government reaffirmed that Turkey remains excluded from the F-35 program due to its continued use of the Russian-made S-400 missile system.
- This follows Turkey’s 2017 purchase of the S-400 despite repeated US warnings, which led to its 2019 expulsion from the multibillion-dollar F-35 fighter jet program.
- The Trump administration enforced legal restrictions established in the 2020 defense legislation that prevent the transfer of F-35 technology to Turkey unless the country removes the Russian S-400 missile system and commits to not acquiring similar equipment going forward.
- Senior Bureau Official Paul Guaglianone affirmed that Washington’s stance has stayed the same, emphasizing that Turkey’s ongoing ownership of the S-400 system does not comply with U.S. legal provisions and defense standards.
- The US continues to seek cooperation and dialogue with Turkey as a longstanding NATO ally but maintains that lifting sanctions or readmitting Turkey risks exposing sensitive military technology to Russia.
