France’s refusal to provide India with access to the core source codes of its Rafale fighter jets has intensified scrutiny over New Delhi’s long-term airpower strategy. The decision affects critical systems, including the Thales RBE2 active electronically scanned array radar, the Modular Data Processing Unit mission computer, and the SPECTRA electronic warfare suite, which collectively underpin the aircraft’s sensor fusion, survivability, and electronic combat capabilities.
Without access to these systems, India would remain dependent on French approval for major modifications, including integrating indigenous weapons like the Astra beyond-visual-range missile or BrahMos air-launched cruise missile. Adjustments to radar algorithms, electronic warfare responses, or mission computer data fusion logic would require coordination with Dassault Aviation and Thales Group.
The issue has gained urgency as India evaluates acquiring up to 114 additional Rafale aircraft under its Multi-Role Fighter Aircraft programme, a deal estimated at approximately US$36 billion. The acquisition is aimed at addressing the Indian Air Force’s current shortfall of fighter squadrons, operating at roughly 31 units against a sanctioned strength of 42.
This development has revived concerns over technological sovereignty and long-term operational autonomy. Analysts warn that restricted software control could constrain India’s ability to independently upgrade the platform or adapt to rapidly evolving threat environments, limiting flexibility during high-intensity electronic warfare scenarios.
The controversy also draws comparisons with Russia’s offer to provide full source code access for the Su-57E export variant, including design documentation and customisation authority. Russian officials have emphasised that Indian engineers could independently modify and modernise the aircraft, aligning with India’s Atmanirbhar Bharat self-reliance objectives.
A previous attempt to acquire 126 Rafale jets under the Medium Multi-Role Combat Aircraft competition was derailed over disagreements on liability, quality control, cost structures, and depth of technology transfer, despite the aircraft being technically selected. A smaller 36-aircraft deal signed in 2016 addressed urgent capability gaps but similarly lacked deep software-level technology transfer.
