IAF Insists on Rafale Source Code Access for AESA Radar, MMC to Enable Independent Weapons Upgrades like Astra and SAAW

The Indian Air Force (IAF) is reportedly advocating strongly for access to the source codes for key systems within its fleet of Dassault Rafale fighter jets, according to defence sources.

This strategic push aims to allow India greater control over integrating its domestically developed weapons onto the advanced aircraft, thereby boosting operational independence and reducing reliance on foreign manufacturers for future upgrades.

India has acquired a full fleet of 36 Rafale jets, which operate from bases including Ambala and Hasimara. While the French manufacturer, Dassault Aviation, has been collaborating with India to integrate specific weapons, such as the Astra Mk1 beyond-visual-range air-to-air missile (BVRAAM) and the Smart Anti-Airfield Weapon (SAAW), control over essential source codes remains with Dassault.

These codes are critical for the Rafale's advanced Active Electronically Scanned Array (AESA) radar and its complex Modular Mission Computer (MMC), which functions as the aircraft's electronic brain.

The IAF's current position is heavily influenced by its extensive experience operating the Dassault Mirage-2000 fleet since the 1980s. Despite nearly four decades of service and significant upgrades to some of these aircraft, the IAF never obtained the source code for the Mirage's mission computer. This limitation historically hindered the seamless integration of India's own emerging weapon systems onto the platform.

An IAF official highlighted the changing landscape, noting that while few indigenous weapons were available during the Mirage-2000's early years, India's Defence Research and Development Organisation (DRDO) and the IAF are now developing numerous advanced air-launched systems.

"There is a pressing need to integrate these into all fighter fleets to maintain commonality and meet operational requirements," the sentiment reflects. Relying on foreign vendors for integration often involves substantial costs and time delays, potentially affecting the force's preparedness.

This initiative aligns with India's broader 'Atmanirbhar Bharat' policy promoting self-reliance, particularly in the defence sector.

The IAF operates a diverse range of fighter aircraft, including the Sukhoi Su-30 MKI and the indigenous Tejas Light Combat Aircraft (LCA), which are increasingly being equipped with Indian systems like the Astra missiles, the Rudram anti-radiation missile, the air-launched BrahMos cruise missile, and the SAAW.

Equipping different aircraft types with the same weapons simplifies logistics, streamlines pilot training, and enhances overall operational flexibility – crucial advantages given India's complex security environment.

However, fitting these advanced Indian weapons onto the Rafale necessitates modifications to the software governing the AESA radar and MMC. Currently, this process depends entirely on Dassault due to the proprietary nature of the source code.

While cooperation on Astra and SAAW integration exists, the IAF seeks the capability to manage future integrations independently. Gaining access to the source code would empower Indian defence scientists and engineers to develop, test, and certify software updates in-house, potentially speeding up deployment and reducing long-term costs.

Understandably, this request presents challenges for Dassault Aviation. Source codes for cutting-edge systems like the AESA radar and MMC represent highly valuable intellectual property, developed through significant investment.

Sharing this sensitive information carries commercial risks and security concerns related to potential espionage or cyber threats that could compromise Dassault's global competitiveness.

Dassault may point to its ongoing cooperation on integrating specific Indian weapons as evidence of its commitment to meeting IAF requirements without handing over complete source code access.

As discussions potentially continue, alternative solutions might be explored, such as providing restricted software development kits (SDKs) or establishing collaborative Indo-French teams dedicated to weapon integration tasks, balancing the IAF's need for autonomy with the protection of sensitive technology.

Yes France will give and we can use it in 36+26 Rafales.

Nice, that is what I always highlight.

The Mirage-2000 saga, a thousand times I have said the Mirage-2000 fighter becomes outdated due to its vintage weapons package plus outdated sensors which Dassault doesn't allow on it. Dassault's game is selling a fighter jet for a one-time profit, but selling sensors and weapons are the lifespan profit of a fighter jet.

Not only weapon integration, the IAF should also try to integrate the latest sensors like GaN-based AESA radar on the Rafale, weapons like Brahmos-NG, Rudram series followed by NASM-MR anti-ship missile which is far better than the French Exocet, which is an outdated missile with only 70 km range. Apart from the Astra series, Python-5 and ASRAAM WVR should too be integrated on the Rafale as well as the Mirage-2000.

I have always given a comparison between the F-16, MiG-29, and Mirage-2000, and in all, the Mirage-2000 has become outdated and can't even compete with the other two with not even PESA radar limitations on detection, while the MiG-29 has been indigenously upgraded from the mission computer to Uttam AESA radar, to the Astra series plus Brahmos-NG in the future, plus NASM-MR in the future, and the Rudram series too.

36+26+40 (potential) = 102, We should ask for source code.

 

[Hari Sud]

France knows that without source code they are always in drivers seat restricting weapons upgrade to French only. Nice position to be.

It's more than 20 years now since we decided to procure 100+ foreign jets for the IAF to replace MiG 21.

20+ years! To take a decision! It was MMRCA to begin with in 2007 with the RFP

and then only 36 jets procured in 2016 with the off-the-shelf purchase instead of local assembly or manufacturing in the G2G deal, ditching the MMRCA for 8 bn USD.

Then again, MRFA in 2016 started with no conclusion in a decade, for 114 jets with RFP not issued yet.

In the meanwhile, the Navy requested 36 jets in 2022, got approval for 26 jets in 2023 and now in 2025 has signed the deal already for 7.5 bn USD!

And the MoD and IAF are now in discussion for 40 to 114 jets with direct purchase or local assembly in G2G deal, scuttling the MMRCA2/MRFA!

Which will probably cost us anything from 8 bn USD to 20 bn USD of taxpayer money again!

The only thing that is "Make in India" is making big fools out of the IAF and the taxpayers after 20 years!

So after spending 15-16 bn USD, we still don't have the source code for the indigenous weapons integration for the mission computer,

exactly as in the case of the Scorpene submarines, isn't it?

Is France really a defence partner and an ally or just another western power who is a weapons supplier who wants to take maximum advantage of our vulnerability with the security situation involving China and its "all-weather" friends!

 

[The Presence]

Just replace their mission computers and radars with our own.

No need of source code in that case.

 

[Sandeep]

No country will ever give away their jets source codes and allow free access to anybody who can sell it, manipulate it or put their own national security at risk.

While they won’t give us any source codes it was agreed that dassault will install and integrate our indigenous weapons so it won’t require any further expensive deals. They just need to install whatever weapons we want to use whenever we develop them which is part of the Rafale deal.
