The Cabinet Committee on Security (CCS) this week cleared a Rs 15,000 crore project to design and develop the Advanced Medium Combat Aircraft (AMCA), India’s fifth-generation fighter multirole fighter jet.

About Advanced Medium Combat Aircraft (AMCA)?

• The AMCA will be India’s indigenous fifth-generation fighter aircraft.
  • The indigenous Light Combat Aircraft (LCA) Tejas is a 4.5-generation single-engine multirole aircraft.
• The Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) will be the nodal agency for executing the programme and designing the aircraft.
• It will be manufactured by state-owned Hindustan Aeronautics Limited (HAL).
• The aircraft will put India in a select group of nations that have their own fifth-generation fighter aircraft.
• Discussions for developing the AMCA started in 2007.
• The initial plan was to jointly develop the aircraft with Russia under a Fifth Generation Fighter Aircraft (FGFA) programme.
  • However, India withdrew from the FGFA project in 2018.

Features of AMCA:

• Stealth: The 25-tonne twin-engine aircraft, which will be bigger that other fighters in the Indian Air Force inventory, will have advanced stealth features to avoid detection by enemy radar.
  • With stealth features, this aircraft (AMCA) would be able to compete with other stealth fighters in the world.
• Fuel & Weapons: The aircraft will have a large, concealed internal fuel tank of 6.5-tonne capacity, and an internal weapons bay for a range of weapons, including indigenous weapons, to be buried in its belly.
• Engine: The AMCA Mk1 variant will have the US-built GE414 engine of the 90 kilonewton (kN) class, while the more advanced AMCA Mk2 will fly on the more powerful 110kN engine, which will be developed indigenously by DRDO’s Gas Turbine Research Establishment (GTRE) in collaboration with a foreign defense major.
  • India has been talking with Safran SA of France, one of the world’s largest manufacturers of aircraft engines and related equipment, in order to finalize the roadmap for the development of the combat aircraft engine
• Another important aspect would be to ensure a higher utilization time and smaller serviceability or maintenance periods for the aircraft.
  • This will be aided by the inclusion of a comprehensive Integrated Vehicle Health Management (IVHM) system to keep track of multiple structural components, and to assess the condition of the aircraft in real time.
• Other features such as a diverterless supersonic inlet for controlling air flow into the engines, and a serpentine air intake duct to shield the engines from radar emissions, are likely to be part of the AMCA.

Other Fifth-generation Fighters:

• Only a few countries have built a fifth-generation stealth fighter aircraft.
• The list of the aircraft currently in service includes:
  • The F-22 Raptor and F-35A Lightning II of the US
  • The Chinese J-20 Mighty Dragon, and
  • The Russian Sukhoi Su-57.
