US F110 engine sale to Türkiye moves forward as Congress does not intervene

A key stage in the US congressional notification process for the sale of F110 engines to be used in Türkiye’s indigenous fifth-generation fighter jet, KAAN, has been completed, with Congress not opposing the sale during the 15-day review period.

Following the US State Department’s formal notification to Congress on June 24 2026, regarding the proposed foreign military sale, several members of Congress introduced a joint resolution seeking to halt the sale during the 15-day review period applicable to NATO allies.

The joint resolution, signed by nine members of Congress and submitted to both the House of Representatives and the Senate, called for blocking the planned sale of certain defence equipment, services, and related support to Türkiye.

However, the resolution was not brought to the floor of either the House or the Senate before the review period expired. As a result, when the 15-day review period concluded on July 9, the sale of the F110 engines moved forward without facing any congressional obstacle.

The notified sale covers the integration, assembly, external modification, certification, testing, defence services, and technical data transfer related to the F110-GE-129E/F engines that will power the KAAN fighter aircraft.

Lawmakers seeking to block sale are familiar opponents

The joint resolution was introduced by Democratic Representative Dina Titus of Nevada, with the support of eight additional Democratic members of Congress.

Among the signatories were several lawmakers who have previously opposed defence sales to Türkiye, including Titus, Brad Sherman, Chris Pappas, and Jim McGovern, all of whom had objected to earlier defence exports such as the sale of F-16 fighter jets to Türkiye.
