New Delhi: India’s Advanced Medium Combat Aircraft programme has taken another important step towards developing the country’s indigenous fifth-generation stealth fighter. The Aeronautical Development Agency (ADA) is moving forward with essential engineering work, including electrical harness design and a major upgrade to its computing infrastructure.
These activities will support aircraft design, digital testing and system integration before physical prototypes are built. The latest developments highlight India’s continued efforts to strengthen its domestic defence and aerospace capabilities.
Advanced Medium Combat Aircraft Programme: ADA Moves Forward With Critical Engineering Work
The Aeronautical Development Agency (ADA), which is responsible for developing the AMCA, has initiated important procurement activities to support the fighter aircraft’s detailed engineering phase.

Two major procurement activities have attracted attention. The first involves designing the aircraft’s electrical harness system, while the second focuses on purchasing advanced computing equipment and network infrastructure.
These activities are important because modern stealth fighters require highly advanced electronic systems, detailed engineering designs and powerful computer-based simulations.
The work will help engineers prepare the technical foundation required for the future AMCA prototypes.
Electrical Harness Design: Building The Aircraft’s Internal Nervous System
One of the major developments is the tender for electrical harness design activities and engineering drawing release. According to the published tender information, the procurement carries the reference number GEM/2026/B/8164482 and was issued on October 15, 2026.
The consultancy contract is planned for approximately two years, with an Earnest Money Deposit (EMD) of ₹10 lakh. The bids were scheduled to open on November 6, 2026.
Why Is Electrical Harness Design Important For AMCA
An electrical harness is a network of wires, cables and connectors that connects different electronic systems inside an aircraft.
It works like the nervous system of a human body because it helps different systems communicate and exchange information. In the AMCA, this network will support several important systems, including:
- Flight control systems.
- Radar and sensor equipment.
- Electronic warfare systems.
- Cockpit instruments and avionics.
- Communication and onboard computer systems.
Engineers must carefully plan the location and routing of every cable inside the aircraft. They must also consider weight, safety, electromagnetic interference and the limited space available inside a stealth fighter.
Proper electrical harness design is important to ensure that different systems work together without creating technical problems. It also helps engineers finalise the internal arrangement of the aircraft before prototype construction progresses further.
Advanced Medium Combat Aircraft Programme: ADA Plans A Major Computing Infrastructure Upgrade
Alongside electrical engineering work, the ADA is also planning a significant upgrade to its computing infrastructure.
Under a separate procurement with reference number GEM/2026/B/8152801, the agency is seeking to acquire 431 computing units and related network infrastructure.
The procurement includes different categories of computing equipment, such as desktop computers, engineering workstations, high-performance workstations, professional laptops, AI mini-workstations and network switches.
The bid submission deadline was extended to November 19, 2026, according to the reported tender corrigendum.
How Will Advanced Computers Support AMCA Development?
Developing a fifth-generation fighter requires advanced digital engineering and computer-based testing. Powerful computing systems help engineers perform several complex tasks, including:
- Computer-aided aircraft design.
- Structural analysis and engineering calculations.
- Flight simulation and modelling.
- Aircraft system integration.
- Software development and testing.
- Digital analysis of aircraft performance.
These activities require significant computing power because modern fighter aircraft contain complex structures and highly advanced electronic systems.
Improved computing infrastructure can help engineers perform simulations, identify possible design problems and improve engineering efficiency before expensive physical testing begins. However, the procurement alone does not confirm that all the new equipment will be used exclusively for the AMCA programme.
Advanced Medium Combat Aircraft Programme Moves Closer To Prototype Development
The latest engineering activities come as India continues to advance its indigenous fifth-generation fighter programme.
In March 2024, the Cabinet Committee on Security (CCS) approved the AMCA programme for design and prototype development.
Later, on May 27, 2025, Defence Minister Rajnath Singh approved the programme’s execution model through industry partnerships.
Under this model, Indian public and private companies can participate independently or through joint ventures and consortia to support prototype development.
The Aeronautical Development Agency is responsible for executing the programme. The government aims to use domestic engineering expertise and industrial capabilities to strengthen India’s aerospace manufacturing ecosystem.
