France’s unwavering decision to deny India access to the Rafale fighter jet’s source code has rekindled strategic frictions, highlighting the challenges of acquiring advanced weaponry when digital sovereignty is not guaranteed. Despite ongoing diplomatic efforts from New Delhi, Dassault Aviation has not agreed to release the essential software that controls the Rafale’s mission systems, weapon integration, and avionics.
India aims to integrate indigenous armaments such as the Astra beyond-visual-range air-to-air missile, Rudram anti-radiation missile, and various smart munitions into the Rafale framework to boost combat independence and lessen dependence on foreign suppliers. This initiative is a key element of India’s ‘Atmanirbhar Bharat’ (Self-Reliant India) vision, which seeks to establish a future where domestic research and development and manufacturing support the nation’s airpower capabilities.
The Rafale, a twin-engine 4.5-generation multirole fighter, is driven by two Snecma M88-2 afterburning turbofan engines and can supercruise at Mach 1.4 without afterburner, providing a high thrust-to-weight ratio and extended operational range. It is equipped with the Thales RBE2-AA Active Electronically Scanned Array (AESA) radar, capable of tracking up to 40 targets and engaging 8 simultaneously at distances over 100 km, making it one of the most sophisticated radar systems available. Additionally, the aircraft incorporates the Spectra electronic warfare suite, which features radar warning receivers, jammers, and infrared missile warning sensors that can identify and counter modern threats through both active and passive measures.
India’s Rafale fleet is enhanced with Helmet Mounted Display Systems (HMDS), Thales Front Sector Optronics (FSO), Infrared Search and Track (IRST), and sophisticated data links for real-time network-centric operations. The Rafale’s combat capabilities include the integration of the Meteor Beyond Visual Range (BVR) missile, which has a no-escape zone exceeding 60 km, the SCALP-EG long-range cruise missile for precision strikes up to 500 km, and the Hammer (AASM) modular air-to-ground precision munitions.
India secured 36 Rafale jets through a €7.8 billion (RM37.5 billion) contract signed in September 2016, with the first jet delivered on 29 July 2020 and the last one arriving on 15 December 2022. The Rafales are currently operational at Ambala Airbase, strategically located near Pakistan, and Hasimara Airbase, close to the Chinese border, both selected for their significance in India’s two-front war strategy.
To bolster maritime strike capabilities, India finalized a US$7.4 billion (RM33.3 billion) deal in April 2025 for 26 Rafale-M fighters, the naval variant, intended for deployment on INS Vikrant and INS Vikramaditya. These carrier-based aircraft will replace the aging MiG-29K fleet, providing India with advanced fourth-plus-generation maritime airpower at sea, which is vital given China’s growing carrier presence in the Indian Ocean. Although there is collaboration on integrating certain Indian-developed munitions such as Astra Mk1 and the Smart Anti-Airfield Weapon (SAAW), France’s reluctance to share the core source code of the Rafale remains a significant barrier to deeper defense cooperation.
The source code in question regulates essential components, such as the Modular Mission Computer (MMC) and the radar-electronic interface necessary for effective weapons integration. Without access to this digital framework, India encounters a capability limitation, unable to independently modify the Rafale for changing operational needs or to carry out software-defined enhancements without French consent.
A senior official from the Indian Air Force, who is knowledgeable about the situation, stated, ‘The lack of access to the source code poses a major challenge to India’s wider defense modernization efforts.’ This issue has sparked a national dialogue about technological independence, drawing uncomfortable comparisons to previous experiences with the Mirage 2000 fleet, where restricted code access impeded local upgrades. ‘Although France has proposed limited cooperation through joint technical teams and constrained software kits, India’s request for complete access underscores its aim to lessen dependence on foreign suppliers and strengthen its defense capabilities autonomously.’
Military strategists contend that access to the code would enable India to swiftly adjust mission parameters, incorporate domestically developed AI-driven subsystems, and optimize logistics without external reliance. Conversely, France maintains that the source code—developed over many years at significant financial investment—is a strategic industrial asset that should not be subject to foreign interference.
The French defense community is concerned that granting access could create a troubling precedent for other Rafale users, such as Egypt, Qatar, and possibly Indonesia, who might seek similar concessions. Additionally, there are genuine worries that access to the source code could introduce security risks, including the potential for reverse engineering, cyber attacks, or unauthorized transfer of French technologies to competing nations.
Additionally, France argues that unauthorized alterations by external parties could jeopardize the integrity of aircraft, safety certifications, and post-sale support agreements, thereby threatening the entire Rafale export initiative. While there are limited workaround options available—such as the integration of Indian munitions through external pods or utilizing fire-and-forget capabilities—these solutions are less than ideal and hinder the complete utilization of Rafale’s sensor-fusion and network-centric warfare capabilities.
Despite the ongoing challenges, the defense relationship between India and France remains strong and continues to grow, highlighted by the April 2025 Rafale-M agreement, which reflects ongoing mutual confidence in sharing advanced technologies, albeit not without limitations. Indian officials assert that the long-term solution lies in the development of indigenous 5th-generation fighters like the AMCA and the enhancement of the Tejas Mk2 program—aircraft designed to ensure full sovereign control over mission systems.
Nevertheless, as global warfare transitions into a software-defined battlefield, the dispute over the Rafale source code serves as a poignant reminder that even the most sophisticated jets are only as sovereign as the software they operate on. While France is resolute in safeguarding the Rafale’s digital core, there are significant precedents where aircraft manufacturers have provided full or partial access to source codes or mission-critical software, particularly to trusted strategic allies.
For example, the United States granted Israel exceptional access to the F-35’s software framework, enabling the Israeli Air Force (IAF) to implement its own command, control, communications, and electronic warfare systems on the “Adir” variant of the stealth fighter. This level of autonomy allows Israel to utilize the F-35 as a sovereign weapons platform, incorporating locally developed air-to-ground munitions and proprietary cyber and electronic warfare systems, while preserving its qualitative military advantage in the region. Likewise, Russia has, in certain instances, provided extensive technical documentation and system access to close partners like India under the Su-30MKI program.
India has been permitted to tailor the Su-30MKI with homegrown technologies, including radar warning receivers developed by DRDO, Astra missiles, and locally produced mission computers. This level of customization has not been afforded by France for the Rafale.
In contrast, South Korea has benefited from a substantial technical transfer in its collaboration with Lockheed Martin on the KF-21 Boramae project, which included access to design blueprints, software integration assistance, and developmental cooperation, although the complete F-35 source code remains under strict control.
Similarly, Sweden’s Saab has proposed full technology transfer and source code access to nations like Brazil in its pursuit of international Gripen sales, enabling Brazil to manufacture and modify the Gripen-E domestically through a collaborative development and production approach.
These instances illustrate that, with appropriate strategic alignment and trust, access to fighter aircraft source code—despite its sensitive nature—is not without precedent. Currently, India’s defense establishment is questioning why such access is granted to certain allies while being denied to them, which is also a crucial strategic partner of the West in the Indo-Pacific region. This perceived double standard has intensified the ongoing discourse in India regarding genuine technological sovereignty in advanced defense procurement.
