AMCA (Advanced Medium Combat Aircraft) · Fifth-generation medium fighter (twin-engine stealth), HAL/ADA development

The AMCA (Advanced Medium Combat Aircraft) is India's programme to develop a fifth-generation, twin-engine, stealth-capable medium fighter — the most ambitious indigenous combat-aircraft project ever attempted by India. Designed by the Aeronautical Development Agency (ADA, a DRDO body) and to be produced by Hindustan Aeronautics Limited (HAL), the AMCA is intended to give the Indian Air Force and Navy a modern stealth fighter that competes with the F-35, Su-57 and J-20 in the medium class, with full Indian design ownership of the airframe, stealth shaping, avionics, sensor fusion and weapons integration. The programme has progressed through concept and detailed design under an approved development budget; the first flight was originally targeted around the mid-2030s but has been delayed from earlier estimates (the programme has slipped). The AMCA will use two GE F414 engines in its initial Mk-1 configuration, stepping to a more powerful engine (a newer/more-powerful engine under consideration) on the later Mk-2. It will carry an internal weapons bay for stealth strike, the indigenous Uttam AESA radar, and Indian air-to-air and strike weapons including Astra and, on later variants, BrahMos-NG-class or SLCM air-launched systems. Strategically, AMCA is the end-point of India's decades-long attempt to achieve genuine fifth-generation combat-aircraft sovereignty — the capability to design, iterate and sustain a modern stealth fighter without dependence on any foreign OEM. It is a direct counterpart to China's J-20 programme and a hedge against reliance on Russian Su-57 or US F-35 imports. Its success or failure will define whether India's military-aerospace industrial base can stand alone at the frontier of the technology.
