Türkiye and United States Explore Creative Solutions to Resolve S-400 Sanctions Dispute

The 2020 CAATSA measures specifically blocked U.S. export licenses and financing for Türkiye’s Presidency of Defense Industries and targeted several senior Turkish officials’ access to U.S. technology and financial markets.
Washington began removing Türkiye from the F-35 Joint Strike Fighter program in 2019, before the CAATSA sanctions were imposed in December 2020; resolving the S-400 dispute could therefore remove a major obstacle to Türkiye’s possible return to the program.
Reports have said Ankara sought Moscow’s approval to transfer the S-400 systems to a third country, and the Kremlin acknowledged that Russia and Türkiye were in contact about the systems’ future, although it did not confirm that a formal permission request had been made.
Turkish officials have not clarified whether the possible resale or transfer of the S-400 systems is connected to the “creative ideas” currently being discussed with Washington.
Türkiye and the United States are discussing unspecified "creative ideas" to resolve a years-long dispute over Ankara's Russian S-400 air-defense systems and lift U.S. sanctions on Turkey's defense industry. Turkish Foreign Minister Hakan Fidan said the two nations are pursuing solutions based on mutual goodwill, but offered no details on specific proposals. Washington imposed sanctions in 2020 under CAATSA and removed Türkiye from the F-35 fighter jet program, citing security risks to NATO.
One possibility circulating in Turkish media is transferring or selling the S-400 systems to a third country, possibly a Gulf state. However, neither Turkish nor U.S. officials have confirmed this as the actual plan being discussed. The dispute has blocked Türkiye's access to advanced Western military technology for over four years.
The U.S. removed Türkiye from the F-35 Joint Strike Fighter program starting in 2019 over concerns that operating Russian S-400 air-defense systems alongside American stealth jets could expose sensitive technology. U.S. officials argued the Russian system's radars could compromise NATO security. The S-400 is one of the world's most advanced air-defense platforms and shares incompatible operating standards with Western equipment.
In December 2020, Washington imposed CAATSA sanctions on Türkiye's Presidency of Defense Industries and blocked U.S. export licenses and financing for Turkish weapons makers. The measures also restricted several senior Turkish officials' access to American technology and financial markets. These sanctions have crippled Ankara's ability to access cutting-edge Western military components and modernize its armed forces alongside NATO allies.
Turkish media reported that Ankara sought Russia's permission to transfer or resell the S-400 systems to a third country. The Kremlin acknowledged that Russia and Türkiye were in contact about the systems' future but refused to confirm whether a formal permission request had been made. Russian officials have shown flexibility on the matter, signaling potential willingness to discuss options without committing publicly.
Turkish officials have not clarified whether a possible resale or transfer of the S-400 systems is directly connected to the "creative ideas" currently being negotiated with Washington. This ambiguity suggests the talks may involve multiple proposals or scenarios still under consideration by both governments.
Resolving the S-400 dispute could unlock Türkiye's return to the F-35 program and restore access to advanced Western military systems. For NATO, bringing Türkiye fully back into joint defense initiatives matters strategically given Ankara's geographic position bridging Europe and Asia. Turkish President Recep Tayyip Erdogan's chief adviser emphasized that U.S.-Turkish ties extend far beyond military cooperation, with NATO remaining a key pillar of their relationship.
