The 15-day review period in the US Congress regarding the sale of F110 engines to be used in Türkiye’s national combat aircraft KAAN has been completed. Since a bill introduced by 9 Congress members to block the sale was not taken up on the agenda, the biggest obstacle in the engine supply process for KAAN has been overcome.
The critical stage has been completed in the notification process to the U.S. Congress regarding the sale of F110 engines to be used in Turkey's national combat aircraft, KAAN. Since Congress did not make a decision to block the sale during the 15-day review period, the sales process will proceed.
9 CONGRESS MEMBERS HAD REQUESTED A BLOCK
Regarding the foreign military sale officially notified to Congress by the U.S. Department of State on June 24, 2026, some representatives submitted a joint resolution to Congress to halt the sale within the 15-day review period applicable to NATO ally countries.
In this joint resolution submitted to the House of Representatives and the Senate with the signatures of 9 Congress members, it was requested to block the sale of certain defense materials and services that the U.S. administration planned to provide to Turkey.
NO OBSTACLE REMAINS TO THE SALE
However, the joint resolution submitted by Congress members was not placed on the agenda of the House of Representatives or the Senate during the review period. Thus, as the 15-day review period ended on July 9, the sales process for F110 engines to Turkey will continue without facing any obstacles in Congress.
The sales notification covers the integration, assembly, external modification, certification, and testing of F110-GE-129E/F engines to be used in the KAAN fighter jet, as well as related defense services and technical data sharing.
THOSE WHO TRIED TO BLOCK THE SALE ARE NOT STRANGERS
The joint resolution was introduced by Democratic Representative Dina Titus of Nevada. Eight other Democratic Congress members supported the resolution.
Among the Democratic members who signed the resolution, those who have previously objected to defense sales to Turkey stand out. House Representatives Brad Sherman, Dina Titus, Chris Pappas, and Jim McGovern have opposed various defense exports to Turkey in the past, including the F-16 sales process.
Other signatories include Jim Costa, Josh Gottheimer, Mike Quigley, and George Latimer, who represent constituencies where the Armenian, Greek, and Israeli diasporas are influential. These individuals are among the groups that have occasionally made defense sales to Turkey a subject of debate in Congress.
HOW DID THE PROCESS WORK?
In the U.S., large-scale arms sales to foreign countries are subject to a specific review process after the State Department officially notifies Congress. For sales to NATO allies, this period is 15 days.
During this period, Congress members can submit a joint resolution to halt the sale. However, for such a resolution to block the sale, it must first be approved by the House of Representatives and the Senate, and then signed by President Donald Trump.
If the President vetoes the resolution, Congress needs a two-thirds majority—at least 290 votes in the House of Representatives and 67 votes in the Senate—to override the veto.
The joint resolution aimed at blocking the sale of F110 engines to Turkey was not placed on the Congressional agenda during the review period, so no legislative process was initiated. Thus, with the completion of the 15-day review period, the sales process will continue without being taken up in the House of Representatives or the Senate General Assembly, and without facing a Congressional blockade.
In the subsequent process, technical and commercial negotiations regarding the supply of F110 engines will continue between the U.S. administration, relevant institutions, and the manufacturer, and the relevant authorities in Turkey. In the upcoming stages, it is expected to address technical topics such as the delivery schedule for the engines, integration work, testing, and certification activities.
