  • The Defence Ministry is progressing with the design and development of the indigenous fifth-generation fighter aircraft (FGFA), Advanced Medium Combat Aircraft (AMCA), with the first prototype expected to be ready by 2028-29.

Key Details:

The AMCA project aims for production to start by 2032-33 and induction by 2034, a decade from project sanction.

  • Significant private sector involvement is planned for the AMCA project, with a model for this to be worked out within the next six months.
  • The Defence Ministry has issued an Expression of Interest (EoI) to the industry and received three responses.
  • The AMCA project is serious as it is India's only FGFA planned for induction amid global advancements in FGFA projects, specifically noting China's progress with its twin-engine J-20 FGFA deployed in Tibet.
  • The Cabinet Committee on Security (CCS) sanctioned the AMCA project in March. It includes a 25-tonne twin-engine stealth aircraft with unique features like an internal weapons bay and diverterless supersonic intake, developed in India for the first time.
  • The AMCA is designed to carry an internal payload of 1,500 kg, an external payload of 5,500 kg, and 6,500 kg of internal fuel. Hindustan Aeronautics Limited (HAL) has initiated manufacturing activities.

Key Features of 5th Generation Aircraft

Stealth Technology

  • Reduced Radar Cross Section (RCS): 5th Generation aircraft are designed to have minimal radar Technologies such as angled surfaces and radar-absorbent materials are employed to achieve this.
  • Infrared Signature Suppression: Measures are taken to reduce the heat signatures emitted by the aircraft, making them less detectable by infrared sensors.

Advanced Avionics and Sensors

  • Sensor Fusion: Integration of data from various sensors provides a complete situational picture. This includes combining inputs from radar, infrared sensors, and other surveillance mechanisms.
  • Active Electronically Scanned Array (AESA) Radar: This allows for quick scanning, better target tracking, and electronic warfare capabilities.

Enhanced Maneuverability

  • Thrust Vectoring: The ability to direct the thrust from the jet engines enhances agility and maneuverability.
  • Advanced Aerodynamics: Designs that enable superior performance in dogfight scenarios.

Network-Centric Warfare Capability

  • Data Link Systems: Enable real-time communication and data exchange with other assets.
  • Interoperability: Seamless integration with other military platforms, such as drones and satellites.

Supercruise Capability

  • The ability to cruise at supersonic speeds without using afterburners, which improves fuel efficiency and reduces thermal signatures.

India’s AMCA Project

India’s AMCA project represents a significant step towards self-reliance in advanced military technology. The AMCA prototype is expected by 2028-29, aligning with India’s strategic defense requirements.

Developmental Milestones.

  • Design and R&D: The initial design phase and research are being conducted by the Aeronautical Development Agency (ADA) in collaboration with the Defence Research and Development Organisation (DRDO).
  • Prototype Development: The prototype will undergo rigorous testing phases, including flight trials to validate its performance metrics.
  • Production and Induction: Following successful trials, production is expected to begin, with induction into the Indian Air Force envisioned in the early 2030s.

Comparative Analysis

Global 5th Generation Fighters

AMCA vs. Global Peers

  • F-35 Lightning II (USA): Known for its stealth and multirole combat capabilities.
  • Sukhoi Su-57 (Russia): Emphasizes maneuverability and advanced avionics.
  • Chengdu J-20 (China): Focuses on stealth and long-range strike capabilities
  • Stealth: AMCA aims to match the stealth capabilities of its global counterparts with advanced materials and design.
  • Cost Efficiency: One of the significant goals of the AMCA project is to offer a cost-effective alternative to Western and Russian aircraft without compromising on advanced features.

Strategic Implications

  • Enhanced Combat Capability: 5th Generation aircraft significantly strengthen a nation’s air superiority, deterrence, and strike capabilities.
  • Indigenous Development: Projects like AMCA promote self-reliance, technological innovation, and indigenous defense manufacturing.
  • Geopolitical Impact: Possession of 5th Generation aircraft influences geopolitical dynamics, offering strategic leverage in regional and global power structures.


The development of 5th Generation aircraft marks a paradigm shift in military aviation, bringing unparalleled capabilities to modern air forces. India’s AMCA project reflects a strategic vision to enhance its defense capabilities through indigenous development. By focusing on advanced stealth, sensor integration, and network-centric warfare, the AMCA stands to place India among the elite nations with cutting-edge combat aircraft, thus stimulating its defense capabilities and geopolitical standing.
