India’s Advanced Medium Combat Aircraft (AMCA) program stands at a crucial juncture as the Defence Research and Development Organisation (DRDO) weighs competing proposals from Britain’s Rolls-Royce and France’s Safran to co-develop the engine for this fifth-generation stealth fighter. The decision, expected by the end of 2025, will fundamentally shape India’s aerospace capabilities and strategic autonomy for decades to come.
While both companies have revised their offers to include 100% Intellectual Property Rights (IPR) and technology transfer, a comprehensive analysis reveals that Rolls-Royce’s proposal offers superior technological advancement, strategic flexibility, and long-term benefits that position it as the optimal choice for India’s ambitious AMCA program.

The Technological Paradigm Shift: 6th Generation Vs 4th Generation Architecture
The most compelling differentiator in Rolls-Royce’s proposal lies in its commitment to developing a clean-sheet, sixth-generation engine design specifically tailored for the AMCA Mk2 variant. This represents a quantum leap beyond Safran’s approach, which fundamentally relies on scaling up the existing M88 engine architecture—a proven but inherently limited fourth-generation design developed in the 1980s.
Rolls-Royce’s offering centres on Variable Cycle Engine (VCE) technology, a hallmark of sixth-generation propulsion systems that allows the engine to dynamically adjust its bypass ratio for optimal performance across different flight regimes. This revolutionary capability enables the engine to switch between high-thrust combat modes and fuel-efficient cruising configurations, providing up to 30% better range and 20% faster acceleration compared to conventional fifth-generation engines. For the AMCA, this translates to enhanced super-cruise capability—the ability to maintain sustained supersonic flight without afterburners—at the required Mach 1.3 speed with over 72 kN of dry thrust.
In stark contrast, Safran’s M88-based proposal, despite planned upgrades through the T-REX program that will increase thrust to 88 kN, remains constrained by its fourth-generation foundation. The M88’s architectural limitations inherently restrict its ability to meet advanced fifth-generation requirements such as extended super-cruise, low infrared signatures, and compatibility with emerging technologies like directed-energy weapons and AI-coordinated systems. Even the upgraded M88 T-REX variant, while offering a 20% thrust increase, maintains the same dimensional constraints and fundamental design philosophy that may prove inadequate for the AMCA’s ambitious performance specifications.

Strategic Autonomy And Complete Technology Transfer
The question of Intellectual Property Rights and technology transfer represents a critical strategic consideration for India’s “Atmanirbhar Bharat” initiative. Historical precedents with French technology partnerships have created legitimate concerns about long-term dependency and restricted access to core technologies.
Rolls-Royce has guaranteed 100% IPR ownership and unrestricted technology transfer for India, ensuring complete control over manufacturing, future upgrades, and potential exports without royalties or licensing restrictions. This commitment extends to establishing comprehensive research and development facilities in India, enabling indigenous innovation and modification capabilities. The British company’s proposal explicitly supports India’s goal of achieving complete strategic autonomy in advanced aero-engine technology.
Safran’s track record in this regard raises substantial concerns. During the 2016-2018 Kaveri-M88 collaboration, Safran insisted on retaining IPR for the engine’s core—the most critical component—while providing minimal technology transfer for less critical components. This approach ultimately led to the collaboration’s collapse, with India unable to achieve the desired level of technological independence. Although Safran has recently revised its stance to offer 100% IPR transfer, the historical precedent of restrictive technology sharing creates scepticism about long-term commitment to genuine technology transfer.

Scalability And Multi-Platform Applications
Perhaps the most visionary aspect of Rolls-Royce’s proposal is its commitment to developing a family of high-thrust turbofan engines ranging from 140-280 kN by adapting the AMCA engine’s core with larger front fans and technical modifications. This scalability offers India unprecedented opportunities to power not only military fighters but also medium and heavy-lift transport aircraft for the Indian Air Force and regional civilian jets envisioned by the National Aerospace Laboratories.
This multi-platform approach creates significant economies of scale and reduces lifecycle costs across multiple aircraft programs, potentially establishing India as a major player in the global aerospace market. The ability to export these engines independently would generate substantial revenue streams and enhance India’s position as a defence technology provider to friendly nations.
Safran’s M88-based approach, while offering potential synergies with the existing Rafale fleet, lacks this broader adaptability. The fighter-centric design philosophy inherently limits its application to combat aircraft, missing the opportunity to create a comprehensive domestic aerospace ecosystem that could support India’s broader aviation ambitions.
Future-Proofing And Technological Evolution
The AMCA program represents India’s entry into the elite club of nations capable of developing fifth-generation fighters. However, the rapid pace of technological advancement in military aviation demands engines that can evolve to support sixth-generation platforms that may replace the Indian Air Force’s Su-30MKI fleet by 2045-2050.
Rolls-Royce’s modular engine design with core upgradeability ensures the technology remains relevant for decades, potentially scaling to 145 kN thrust for future applications. The incorporation of advanced features like adaptive cycle technology, sophisticated thermal management, and AI-integrated systems positions the engine as a foundation for India’s long-term aerospace strategy.
The M88-based approach, despite planned upgrades, fundamentally limits future evolution due to its fourth-generation architectural constraints. While Safran has committed to developing Variable Cycle Engine technology, implementing such advanced features within the constraints of an existing fourth-generation design presents significant technical challenges.

The Clear Strategic Choice
The comparison between Rolls-Royce’s sixth-generation clean-sheet design and Safran’s M88-based proposal reveals fundamental differences in technological ambition, strategic vision, and long-term value proposition. While Safran offers the advantage of existing relationships and proven technology, these benefits are overshadowed by the limitations inherent in fourth-generation architecture and historical concerns about technology transfer restrictions.
Rolls-Royce’s commitment to developing truly advanced sixth-generation engine technology, combined with guaranteed 100% IPR ownership, multi-platform scalability, and comprehensive technology transfer, positions it as the superior choice for India’s AMCA program.
The proposal not only meets the immediate requirements of the fifth-generation fighter but also establishes a foundation for India’s broader aerospace ambitions and long-term strategic autonomy.
The decision facing GTRE extends beyond technical specifications to encompass India’s vision of becoming a global aerospace power. Rolls-Royce’s transformative proposal offers the technological leap necessary to achieve this ambition, while Safran’s evolutionary approach, despite recent improvements, remains constrained by its fourth-generation origins.
For India’s AMCA program to truly fulfil its potential as a cornerstone of future air power, the choice is clear: Rolls-Royce’s sixth-generation engine technology represents the optimal path forward for achieving technological superiority, strategic independence, and long-term competitiveness in the global aerospace arena.
