The deadlock over Turkey’s return to the F-35 programme has intensified as the U.S. State Department reaffirmed that Ankara has not met the legal requirements for re-entry. In a July 22 letter to Congress, the State Department reiterated that U.S. law prohibits the transfer of F-35 aircraft while Turkey retains its Russian-made S-400 air-defence systems. To qualify, Turkey must remove the missiles, guarantee they will not be procured again, and meet remaining certification requirements. While President Donald Trump has described Turkey as a “loyal ally” and signaled a willingness to consider sales, President Recep Tayyip Erdoğan has claimed the United States committed to delivering five F-35 aircraft. This discrepancy highlights a growing gap between executive rhetoric and legal realities. Security concerns have expanded beyond the S-400 issue. Analysts warn that Turkey’s use of Chinese Huawei technology in its 5G infrastructure could create a “back-door” for espionage on sensitive F-35 data. Furthermore, experts note that the six F-35 jets already paid for by Ankara remain in the U.S., and their acquisition could allow the Turkish defense industry to study sensitive components, potentially shifting the strategic balance in the Aegean and Eastern Mediterranean. Efforts to resolve the impasse remain stalled. Simply storing the S-400s on Turkish soil is insufficient for U.S. officials, while transferring the systems to third countries like Qatar or the UAE faces significant diplomatic and technical hurdles. The dispute continues to test U.S. foreign policy and the stability of the NATO alliance. Recent developments suggest the U.S. may be considering reinstating Turkey into the F-35 program, with President Trump indicating he may lift CAATSA sanctions. This potential shift has met strong opposition from Israel; Prime Minister Benjamin Netanyahu has argued that providing Turkey with F-35 capabilities would disrupt the regional balance of power and undermine Israel's qualitative military edge.
