India Goes For The KILL! Ex-IAF VCAS Explains Why 5th-Gen AMCA Program Could Revolutionize Indian Military. (Part 1)
India’s quest for self-reliance in defence technology has reached a pivotal milestone with the approval of the Advanced Medium Combat Aircraft (AMCA) Programme Execution Model on May 26, 2025.
This model, greenlit by Defense Minister Rajnath Singh, introduces a collaborative and competitive framework to accelerate the development of India’s first indigenous fifth-generation stealth fighter jet.
Designed by the Aeronautical Development Agency (ADA) under the Ministry of Defence, the AMCA is a 25-tonne, twin-engine, multirole stealth aircraft intended to bolster the Indian airpower capabilities by 2035.
The new execution model emphasises private sector involvement, international collaboration, and a competitive bidding process, significantly departing from traditional defence procurement practices.
Advanced Medium Combat Aircraft
AMCA is India’s fifth-generation stealth fighter jet program, developed by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO).
Designed as a multi-role, twin-engine aircraft, the AMCA aims to replace aging fleets such as the SEPECAT Jaguar and Mirage 2000, while complementing the Rafale and the future Tejas Mk2 in the Indian Air Force (IAF).
The 25-tonne, twin-engine AMCA features stealth shaping, internal weapons bays, and advanced sensor fusion. It is intended to excel in air superiority, deep strike, and electronic warfare missions.
It will have an advanced avionics suite, Indigenous AESA radar, and potentially AI-based mission systems.
The aircraft is envisioned in two phases: Mark 1, featuring current-generation technologies and imported engines, and Mark 2, incorporating indigenous sixth-generation features and an Indian powerplant.
The AMCA is strategically significant as it will enhance India’s air combat capabilities and reduce reliance on foreign platforms.
Strategic Significance Of AMCA
The AMCA is not just a defence project but a strategic lever and India’s entry ticket into the elite club of fifth-generation fighter operators. The AMCA program is crucial in countering regional threats, particularly those posed by China and Pakistan.
China’s deployment of J-20 and J-35 stealth fighters in the future, with plans to supply 40 J-35s to Pakistan, underscores the urgency of AMCA’s development.
The IAF’s modernisation drive, aiming for 42 squadrons by 2035, relies on the AMCA to maintain a technological edge. The collaborative model’s success could position India among the elite nations with fifth-generation fighters, alongside the US, China, and Russia.
Historical Progress: Bottlenecks
The AMCA program was conceived in the early 2010s as a follow-on to the Light Combat Aircraft (LCA) Tejas. However, despite its strategic importance, progress was tepid due to multiple challenges.
Initial timelines projected a first flight by 2020 and production by 2025, but these slipped to 2028 and 2038-39 due to funding constraints and bureaucratic delays.
The program’s preliminary design phase began in 2015, with CCS approval only in 2024. The Tejas program’s prolonged development (from the 1980s to the late 2010s) is a cautionary tale, highlighting systemic issues in India’s defence ecosystem.
The program lacked an empowered governance structure, slow decision-making, and HAL’s overburdened capacity. The absence of an indigenous high-thrust engine has been a persistent hurdle for the program; the Kaveri engine program’s inability to meet requirements forced reliance on foreign engines, delaying self-reliance.
India lacked expertise in advanced technologies and high-thrust engines, necessitating foreign collaboration.
The withdrawal from the Indo-Russian FGFA project in 2018, due to disagreements over technology transfer, forced a fully indigenous approach, thereby increasing technical risks. The new execution model addresses many of these issues by decentralising authority, attracting capital, and professionalising development.
Boosting The AMCA Program
Collaborative Execution Model
Announced on May 26, 2025, the AMCA Programme Execution Model introduces a public-private partnership (PPP) framework, moving away from the traditional reliance on Hindustan Aeronautics Limited (HAL) as the sole manufacturer.
The new model proposes a Special Purpose Vehicle (SPV)-based framework, with a private sector partner working alongside the Aeronautical Development Agency (ADA), Hindustan Aeronautics Limited (HAL), and the Indian Air Force (IAF).
Under this model, the ADA will issue an Expression of Interest (EoI) to public and private entities, allowing them to bid independently or as consortia. The model offers flexibility to include global OEMs as technology partners or equity stakeholders in the SPV.
This shift signifies a bold experiment breaking free from India’s traditionally state-dominated defence production ecosystem. It promises to enhance project accountability, bring commercial rigour to execution, and facilitate foreign direct investment and technology infusion.
The competitive approach aims to streamline development, reduce costs, and integrate cutting-edge technologies. One of the most progressive steps is to move from a nomination-based to a competitive merit-based selection model. The collaborative model is expected to provide several key benefits to the AMCA program.
Encouraging Efficiency & Speed
By involving private sector firms alongside HAL, the model diversifies the production base, reducing bottlenecks associated with a single manufacturer. Private companies would bring agility, innovation, and financial muscle, which can accelerate manufacturing and delivery timelines.
The Ministry of Defence (MoD) has emphasised reducing timelines. Firms will be incentivised to optimise costs and timelines to win bids, reducing the bureaucratic delays that plagued earlier phases of the AMCA program.
The Combined Quality Cum Cost Based System (CQCCBS) model will evaluate bids based on technical and financial merits, ensuring high-quality outcomes.
Technology Integration
Including private firms would enable access to advanced manufacturing techniques and expertise in composites, avionics, and AI. The collaboration is expected to enhance the AMCA’s technological edge, aligning it with global fifth-generation standards.
Economic & Industrial Growth
The model would foster a robust domestic aerospace ecosystem, generating employment and technological advancements. By distributing work packages among private firms, the program stimulates investment in infrastructure and skilled workforce development, aligning with India’s “Atmanirbhar Bharat” vision for self-reliance.
Risk Mitigation
The collaborative approach spreads financial and technical risks across multiple stakeholders, reducing the burden on HAL and the government. This is particularly crucial given the program’s history of delays and funding shortages.
Technological Challenges
However, challenges remain. Establishing fighter jet manufacturing facilities requires significant investment, and private firms may face hurdles in acquiring land, infrastructure, and skilled labour.
Scepticism persists about their ability to match HAL’s experience, which could lead to initial teething issues. The AMCA’s development involves overcoming significant technological hurdles, particularly in stealth and engine capabilities.
Stealth Technology
Achieving a low radar cross-section (RCS) is critical for the AMCA’s fifth-generation credentials. The AMCA incorporates a twin-tail layout, platform edge alignment, and diverterless supersonic inlet (DSI) with serpentine ducts to conceal engine fan blades. However, refining radar deflection capabilities is essential.
India is developing RAM to reduce RCS, with IIT Kanpur’s Anālakṣhya Meta-material Surface Cloaking System (MSCS) enhancing stealth against Synthetic Aperture Radar (SAR). Scaling this technology for industrial production remains a challenge.
Stealth design compromises aerodynamics, reducing manoeuvrability. Balancing these aspects requires advanced computational modeling and wind tunnel testing.
Engine Capabilities
The AMCA’s supercruise and thrust vectoring requirements demand a high-thrust engine, posing significant challenges. India’s lack of indigenous jet engine technology remains a bottleneck.
Achieving sustained supersonic flight without afterburners and enabling thrust vectoring for enhanced manoeuvrability requires advanced engine designs. Integrating these systems into the AMCA’s airframe is technically demanding.
The Kaveri engine project highlighted the gaps in materials science and manufacturing precision, necessitating the need for foreign expertise.
International Collaboration
The AMCA program’s success hinges on the participation of robust private sector and international partners. Opening the doors to foreign OEMs and global collaboration is a key differentiator of the new model.
Foreign OEMs from Russia, France, the UK, and the US are expected to play a crucial role, particularly in addressing technological gaps. Several roles are envisioned for global partners.
Collaborations ensure technology transfer, critical for building India’s aerospace capabilities. Technology transfer is expected, particularly for stealth shaping, radar-absorbing materials (RAM), advanced avionics, and sensors. Foreign partners can provide expertise in radar-absorbing materials, low-observable designs, and Active Electronically Scanned Array (AESA) radar systems.
