A proposal introduced by a Democratic member of Congress would limit or block the export of the American F110 engines that Turkey relies on for its fifth‑generation fighter, the TAI KAAN. If approved, the roughly $700 million contract for engine sales and related services to Turkey could be halted. Turkey plans to use the U.S. engines in the early phase of the program and switch to its domestic TF35000 engines from 2032, but a stop in exports could delay the mass production of the KAAN by several years, potentially into the 2030s. Analysts note that Turkey’s strained relations with some NATO members and regional disputes may influence the congressional decision, though the likelihood of the restriction being enacted is considered low.
