# U.S. Conditions Türkiye F-35 Sale

The United States says Türkiye cannot receive F-35 aircraft or rejoin the program while it possesses Russian-made S-400 air defense systems, citing conditions in the National Defense Authorization Act (NDAA). Secretary of State Marco Rubio described the purchase as impossible until those conditions are met. The signal provides no delivery timeline, contract value, or solicitation details, so the prospective sale remains contingent rather than a defined near-term procurement opportunity.

- Aerospace and defense contractors should treat a potential F-35 sale to Türkiye as dependent on resolution of the S-400 issue; no award or delivery schedule is identified.
- Companies assessing exposure to the opportunity should distinguish the conditional prospect from funded, solicited work and account for the statutory conditions cited in the signal.
