After years of US restrictions.. Türkiye might have a solution to the dilemma of modernizing the Egyptian F-16
Military relations between Egypt and Turkey witnessed remarkable development during the period between June 4 and 17, with the implementation of joint air training in a number of Egyptian air bases with the participation of multi-mission fighters, including Turkish F-16 aircraft. While official statements focused on traditional goals of exchanging experiences, unifying combat concepts, and raising the level of operational readiness, the implications of this military activity appear broader than just routine maneuvers.
The training comes within an accelerated path of military rapprochement between the two countries. In February 2026, a framework agreement for military cooperation was signed in Cairo, followed by a direct meeting between the commanders of the air forces of the two countries, which reflected the transition of relations from the stage of political and diplomatic rapprochement to the level of practical military cooperation in the fields of training, armament, and operational coordination.
In the midst of this rapprochement, some media reports circulated information indicating the possibility of Egypt obtaining what is described as the “secret code” for the F-16 fighters through Turkey, after the United States refrained from providing it to Cairo. This concerns a set of software, mission management systems and flight computers that allow the integration of weapons, radars and local systems on the aircraft.
Although Turkey has made significant progress in modernizing its fleet of F-16 fighters through the “Ozgur” project, which includes software development and the introduction of active electronic scanning radars, defense reports indicate that Ankara does not have full access to all the software of the original American versions of the aircraft, especially with regard to some of its advanced versions.
Here the main obstacle arises, as the F-16 fighters are of American origin, and any transfer of technology, software or services related to them is subject to strict American controls and permits. Therefore, observers believe that the most realistic possibility is for Cairo and Ankara to search for an independent Turkish modernization package or specific integrative solutions, and not to transfer the “secret code” in the sense circulated in the media.
These discussions are particularly important given that Egypt has one of the largest F-16 fleets in the world, at a time when the issue of modernizing these fighters and arming them with long-range weapons has been on the table for years. Although Washington agrees during 2025 to new arms deals for Cairo, this does not automatically mean that all Egyptian fighters will have the full operational capabilities to use various advanced systems and weapons.
Turkey is constantly working to develop its defense capabilities based on its own capabilities, whether in the field of drones, missiles, or radar systems, with a parallel effort to strengthen its defense relations with Arab countries and neighboring countries within a broader vision of regional security.
This vision indicates that the current regional environment, with its multiple tensions and conflicts, is pushing towards increasing levels of military cooperation between countries in the region, including major Arab parties, within the framework of the concept of “common security” to confront the escalating challenges.
Regarding the file of military technology transfer, the Turkish approach - according to this vision - is to provide a greater degree of technical cooperation with regional partners compared to some Western powers, including joint production or development projects in areas such as drones and weapons systems.
As for the controversy related to what is known as the “secret code” for the F-16 fighters, it falls within the framework of strict agreements and controls with the United States, which makes the transfer of software or sensitive systems extremely complex and restrictive. On the other hand, Türkiye has developed some special software capabilities that allow for improvements to the aircraft’s systems and the integration of different armaments, without this meaning owning or transferring the original copy of the American software.
This type of military cooperation also comes within the framework of existing international understandings, which confirms adherence to agreements and not exceeding them, even in light of the sensitivity that some areas of technical cooperation may raise among other parties.
The “Ozgür” project (ÖZGÜR) is one of the most important defense modernization programs developed by Turkey to modernize F-16 fighters locally, with the aim of reducing dependence on American systems for updating software and avionics, and raising the capabilities of the Turkish fleet of these fighters, which are the backbone of the Turkish Air Force.
The project focuses on redesigning and developing the mission computers and flight and combat management software inside the aircraft, so that they become capable of integrating locally-made weapons systems, radars, and electronic warfare devices. This also includes developing display interfaces, navigation and guidance systems, giving the pilot a greater ability to use modern Turkish weapons without having to fully rely on original American software.
The project began in practice on older versions of the F-16 fighters, especially the Block 30, where extensive upgrades were made to the plane's mainframe, allowing the integration of Turkish-made munitions such as laser-guided bombs and local smart weapon systems. Over time, upgrades expanded to include improvements in radar and communications systems and integration with modern munitions.
Through Ozgür, Ankara seeks to achieve a higher degree of software independence in the field of military aviation, so that it becomes able to modernize its fighters without the need for complex external approvals, which represents a sensitive point in light of the fact that F-16 aircraft were originally subject to strict US export restrictions within the ITAR system.
But despite this progress, the project remains, according to defense estimates, primarily focused on software upgrades and partial reverse engineering, rather than a complete reproduction of the original F-16 system. Also, some advanced versions of the aircraft, especially the latest ones, are still not fully modified due to technical and political restrictions.
The importance of “Ozgur” is not limited to modernizing the Turkish F-16 aircraft only, but extends to being a strategic step towards building a local technological base in the field of combat aviation systems, which can later be used in Turkish new generation fighter projects such as the “KAAN” project.
