A US Representative has initiated a move to halt a potential engine deal between the US and Turkey for Ankara's KAAN fighter jet program. Representative Dina Titus introduced a resolution of disapproval in the House of Representatives, aiming to prevent the sale of US-licensed engines to Turkey. This action adds further strain to the already complex defense relationship between Washington and Ankara. The challenge coincides with renewed scrutiny surrounding Turkey’s prior involvement—and subsequent removal—from the F-35 fighter jet program. Concerns over Turkey’s defense acquisitions and geopolitical alignment appear to be driving the Congressional opposition. The resolution seeks to formally block the engine deal, potentially impacting the development of Turkey’s domestic fighter capabilities. This represents a significant development in US-Turkey defense cooperation.
