The U.S. Congress's 15-day review period on the sale of General Electric (GE) F110 jet engines to Türkiye for use in its KAAN national fighter jet has expired, allowing the sale to proceed without being taken up by the full House of Representatives or the Senate.

The U.S. State Department formally notified Congress of the proposed foreign military sale on June 24, 2026. Under the 15-day review period applied to sales involving NATO allies, several lawmakers submitted a joint resolution seeking to block the sale, requesting that the Trump administration's planned sale of specific defense equipment and services to Türkiye be halted.

The joint resolution, submitted to both the House and the Senate with the signatures of nine members of Congress, was not taken up by either chamber during the review period.

As a result, with the 15-day window completing on July 9, the sale of F110 engines to Türkiye will proceed without facing any congressional obstacle.

The sale notification covers the integration, assembly, external modification, certification and testing of F110-GE-129E/F engines for use in the KAAN fighter jet, along with related defense services and technical data sharing.

Democratic Reps who blocked sale

The joint resolution was introduced by Democratic Rep. Dina Titus of Nevada, with eight additional Democratic members of Congress supporting the measure.

Among the Democratic co-sponsors were lawmakers who have previously objected to defense sales to Türkiye. Representatives Brad Sherman, Dina Titus, Chris Pappas and Jim McGovern have opposed various defense exports to Türkiye in the past, including the F-16 sale process.

Other co-sponsors, Jim Costa, Josh Gottheimer, Mike Quigley and George Latimer, represent districts with significant Armenian, Greek and Jewish diaspora communities, groups that have periodically factored into congressional debates over defense sales to Türkiye.

How Congressional review process works

Major U.S. arms sales to foreign countries undergo a review process after the State Department formally notifies Congress. For sales to NATO allies, this review period is 15 days.

During that window, members of Congress can introduce a joint resolution seeking to block the sale. For such a resolution to actually stop a sale, it must first pass both the House and the Senate, then be signed by the President. If the President vetoes the resolution, Congress would need a two-thirds majority to override it, at least 290 votes in the House and 67 in the Senate.

While a joint resolution of disapproval was introduced in the House to block the F110 engine sale to Türkiye, it failed to advance or gain traction in either chamber during the review window. With the statutory 15-day review period now complete, the sale will proceed without further congressional obstacles or formal floor intervention from either the House or the Senate.

Technical and commercial negotiations on the F110 engine procurement will continue between the U.S. administration, relevant agencies, the manufacturer, and Turkish authorities.

Later stages of the process are expected to address technical matters, including the engines' delivery timeline, integration work, and testing and certification activities.
