Evolution and Milestones of the India’s much ambitious AMCA Project-Where we stand and expected outcomes

The Advanced Medium Combat Aircraft (AMCA) is India’s flagship program to develop a 5th-generation multi-role fighter stealth. Managed by the Aeronautical Development Agency (ADA) under the Ministry of Defence, the project has transitioned from a design concept into a full-scale development phase as of late 2025.This project aims to develop India’s first fifth generation stealth fighter jet, with collaboration involving other organizations like the Defence Research and Development Organisation (DRDO) and Hindustan Aeronautics Limited (HAL). 

Here is the current status and factual breakdown of the project based on the most recent developments.

Evolution of AMCA-India’s fifth generation stealth Aircraft Fighter project

AMCA Phase 1: Conceptualization & Early Design (2008–2017)

• 2008: The project was first announced as a “Medium Combat Aircraft” (MCA) to fill the gap between the Light Combat Aircraft (Tejas) and heavier Su-30MKI.
• 2010: Renamed to Advanced Medium Combat Aircraft (AMCA) to signify its 5th-generation status (stealth, internal weapons, etc.). Initial seed funding of ₹90 crore was sanctioned for feasibility.
• 2013: A 1:8 scale model was first showcased at Aero India, revealing the basic “diamond-shaped” stealth airframe design.
• 2015: The design was refined into a twin-engine configuration to meet the Indian Air Force’s (IAF) requirements for “Deep Penetration” strikes.

AMCA Phase 2: Design Freeze & Technical Validation (2018–2022)

• 2018: The project definition phase was completed. The government sanctioned additional funds (~₹450 crore) for a detailed design.
• 2019–2021: ADA achieved Design Freeze. Wind tunnel testing and Stealth Geometry validation (to reduce Radar Cross Section) were completed.
• 2022: Structural metal cutting for the first prototype began at HAL, signaling the transition from paper to production.

AMCA Phase 3: Sanction & Execution (2023–2025)

• March 2024: The Cabinet Committee on Security (CCS) officially sanctioned the project with a budget of approximately ₹15,000 crore for the development of five prototypes. The goal is to build a 25-tonne, twin-engine fighter featuring advanced stealth, supercruise capabilities, and “sixth-generation” technologies in later variants.
• February 2025: A full-scale engineering model of the AMCA was publicly demonstrated at Aero India 2025, manufactured by VEM Technologies (private sector).
• May 2025: Defence Minister Rajnath Singh approved the AMCA Execution Model. This broke the HAL monopoly, allowing private players like Tata or L&T to compete or form consortia for production.
• December 2025 (Current): Structural assembly of the first prototype is underway. Discussions are finalized with Russia (for Izdeliye-177S tech transfer) and France (Safran) to co-develop a high-thrust engine for the future Mk2 variant.

A New Execution Model (Public-Private Partnership for manufacturing of AMCA prototype)

A major shift occurred in May 2025, when the Ministry of Defence approved a new “Industry Partnership” execution model.For the first time, the production will not be the exclusive domain of state-run Hindustan Aeronautics Limited (HAL). In June 2025, an Expression of Interest (EoI) was released to shortlist Indian private sector companies to partner with ADA.

Private firms had until September 30, 2025 to submit Expressions of Interest for the AMCA program. Media reports indicate that seven companies responded to DRDO ADA’s Rs 15,000 crore design and development bid by the deadline.

The Bidders: Who are the Contenders?

The companies and consortia that submitted their Expressions of Interest (EoI) include:

1. VEM Technologies: Known for building the full-scale AMCA model, they are a strong contender for high-precision manufacturing.
2. Larsen & Toubro (L&T) + Bharat Electronics Limited (BEL): A heavyweight partnership combining L&T’s complex engineering with BEL’s expertise in stealth avionics and radar.
3. Tata Advanced Systems Limited (TASL): Competing independently, leveraging their experience in manufacturing airframes for global giants like Boeing and Airbus.
4. Hindustan Aeronautics Limited (HAL): The state-run incumbent, which has proposed a Joint Venture (JV) model where it holds 50% and divides the rest among private partners.
5. Adani Defence & Aerospace: Partnering with MTAR Technologies, aiming to utilize their growing aerospace manufacturing ecosystem.
6. Kalyani Strategic Systems (Bharat Forge): Teamed up with BEML and Data Patterns to provide a vertically integrated solution covering structures and electronics.
7. BrahMos-led Consortium: An alliance involving BrahMos Aerospace Thiruvananthapuram Ltd (BATL), Goodluck India, and Axiscades.

Stealth Features (Low Observability)

• The AMCA is designed for “Front Aspect Stealth” to penetrate contested airspace undetected.
• S-Shaped Air Intakes: Serpentine ducts mask the engine fan blades from radar waves, a critical 5th-gen requirement.
• Internal Weapons Bay (IWB): To maintain a clean, stealthy profile, weapons are carried inside the fuselage.
• Radar Absorbent Materials (RAM): The airframe is treated with specialized paints and a Meta-material Surface Cloaking System (Anālakṣhya) developed by IIT Kanpur to absorb microwave signals.
• Diverterless Supersonic Inlet (DSI): Removes the need for heavy, radar-reflecting diverter plates, improving both stealth and engine efficiency.

Engine & Performance

• The project follows a two-stage engine roadmap:
• AMCA Mk1: Powered by two General Electric F414-INS6 engines (approx. 98 kN thrust each).
• AMCA Mk2: Will feature an indigenous 110–120 kN high-thrust engine (currently being co-developed with partners like Safran or Rolls-Royce).
• Max Speed: Mach 2.15 (~2,600 km/h).
• Supercruise: Ability to sustain supersonic flight without afterburners (targeted primarily for the Mk2).
• Range: Combat radius of over 1,000 km in stealth mode; ferry range of over 5,300 km with external tanks.

 Avionics & Sensor Fusion

• The aircraft functions as a “Software-Defined” platform:
• Radar: An advanced Uttam AESA Radar using Gallium Nitride (GaN) technology, featuring 1,528 transmit-receive modules for long-range, low-probability-of-intercept (LPI) tracking.
• AI-Enabled Electronic Pilot: An artificial intelligence system that assists the pilot with sensor fusion, data prioritization, and automated threat assessment.
• Integrated IRST: An Infrared Search and Track system for passive (stealthy) detection of enemy heat signatures.
• Panoramic Cockpit: A single wide-area touch display with a holographic Head-Up Display (HUD) and voice-activated commands.

 Weaponry & Payload

• The AMCA operates in two distinct modes:
• Stealth Mode: Internal carriage only (~1,500 kg payload). Typically 4× Astra Mk1/Mk2 BVR missiles or a mix of smart bombs. Recent redesigns for Mk2 aim to increase this to 6 missiles.
• “Beast” Mode: External carriage on 6 wing hardpoints (+ internal bay) for a total payload of 6,500 kg. Used after air superiority is established.
• Arsenal: Includes Astra (Air-to-Air), BrahMos-NG (Standoff Cruise Missile), Rudram (Anti-radiation), and SAAW (Smart Anti-Airfield Weapon).

Realistic Timeline and Status of AMCA project

While official targets remain optimistic, industry analysts and recent reports from December 2025 suggest the following timeline:

• Prototype Rollout: Target is 2028–2029.
• First Flight: Projected for 2029–2030.
• Operational Induction: The Indian Air Force (IAF) expects to begin inducting the AMCA Mk1 by 2034–2035.
• Mk2 Delay: Due to the complexities of developing a high-thrust engine from scratch, the AMCA Mk2 induction is increasingly likely to slip toward 2040.

AMCA vs Rivals

This project is viewed by the MoD as a critical necessity to counter the Chinese J-20 and the reported Pakistani interest in the J-35A, as India’s current squadron strength remains below the sanctioned 42-squadron requirement.

Here is a comparison of India’s AMCA (Advanced Medium Combat Aircraft) with the American F-35 Lightning II and the Chinese Chengdu J-20, which are currently the leading 5th-generation fighters regionally and globally, as per your request.

• Weight Class & Role: The AMCA is a Medium-Weight fighter, designed to be more agile than the J-20 but heavier than the Tejas. The F-35 is a multi-role “strike” fighter focused on sensor fusion, while the J-20 is a “heavy-weight” air-superiority interceptor designed for long-range engagements.
• The “Speed” Advantage: On paper, the AMCA is designed for a higher top speed (Mach 2.15) than the F-35 (Mach 1.6). This reflects India’s tactical requirement for rapid interception across high-altitude Himalayan borders.
• Stealth vs. Versatility: The F-35 remains the gold standard for Very Low Observability (VLO). The AMCA aims for similar stealth levels through a “serpentine” intake and internal bays, but unlike the F-35, it prioritizes Supercruise (the ability to fly supersonic without using fuel-heavy afterburners), a feature the F-35 largely lacks.
• The Technology Gap: While the J-20 and F-35 are flying in the hundreds, the AMCA’s biggest challenge is the 2029-2030 flight window. By the time AMCA enters service (mid-2030s), the F-35 and J-20 will likely be receiving “6th-generation” software and engine upgrades.
