Why Tejas MkII Matters for India's AMCA Development

India's pursuit of a homegrown, technologically superior fifth-generation fighter aircraft received a significant push with the recent Cabinet Committee on Security (CCS) approval for the Advanced Medium Combat Aircraft (AMCA) development program.

While the AMCA represents a leap in India's aerospace capabilities, its success heavily hinges on the less glamorous but equally crucial Tejas MkII program. The MkII acts as both a technological stepping stone and an essential "feeder" system, paving the path toward the AMCA's realization.

Beyond an Upgrade: The MkII as a Testbed​

The Tejas MkII isn't just an upgraded version of the existing Tejas fighter; it's a critical incubator for the advanced technologies that will define the AMCA.

By testing and refining these systems on the MkII, India significantly reduces the risks associated with integrating them directly into the more complex AMCA program. This approach accelerates development timelines and enhances the AMCA's chances of success.

Shared DNA: Line Replaceable Units​

One critical aspect of the technological bridge between the Tejas MkII and AMCA is their extensive use of shared Line Replaceable Units (LRUs). These modular components form the core of an aircraft's various systems.

Sharing LRUs streamlines the AMCA's development, reduces costs, and ensures a smoother technological transition between the two aircraft.

Cutting-Edge Tech: What the MkII Brings to the Table​

The Tejas MkII will be a flying laboratory for several technologies intended for the AMCA. Here's a look at some of the key advancements:

• Wide Area Display (WAD): A panoramic cockpit display offering pilots unprecedented situational awareness.
• Sensor Fusion: The integration of data from multiple sensors for a comprehensive battlefield overview.
• Side-stick Controller: Improved ergonomics for pilot comfort and precision control during maneuvers.
• Electronic Pilot: An AI-assisted system to aid pilots in flight control and decision-making.
• Digital Flight Control Computer (DFCC): Advanced computer systems ensuring stable, accurate flight control.
• Weapons Management Computer: Precision management and deployment of the AMCA's diverse weapon systems.
• Auxiliary Computer: Additional processing power for complex onboard calculations.
• Unified Video and Data Recorder: Capture of vital flight information for analysis and improvement.

Beyond Components: Cockpit and Radar​

In addition to specific LRUs, the MkII's "Smart Cockpit" – with advanced displays and human-machine interface (HMI) – will provide a blueprint for the AMCA's interface.

The improved Uttam AESA radar, based on Tejas Mk1A's radar and further enhanced with Gallium Nitride (GaN) technology, directly contributes to the AMCA's powerful sensor suite.

Conclusion​

The Tejas MkII is far more than just a stepping stone towards India's fifth-generation fighter ambitions; it's a critical proving ground for essential technologies.

The successful integration and testing of these systems on the MkII will not only reduce risk for the AMCA but will also provide invaluable data and experience for India's aerospace engineers.

This methodical approach is a testament to India's determination to develop a truly indigenous and cutting-edge fighter aircraft program.

In terms of long term Logistical synergy & Economy of Scales, it's better that IAF & Indian-Navy should consider to form a JV to invest in:-

1. TEDBF (ORCA)
2. AMCA

 

[Apocalypse gupta]

We will make AMCA MK1 first, AMCA MK2 will happen eventually.

I know. But amca mk 2 will come online at around same time as NGAD, tempest etc come online. (Other 6th gen fighters)

 

[Mridul baruah]

Mk1A is delayed. Won't fly with a working on flight refuelling probe. Fir batein karenge 5th - 6th Generation ki.

I am thinking practical with no delusions, Tejas MK2 prototype may be flying in 2030 but not AMCA, according to current AMCA design, it’s an evolution of TEDBF/ORCA, so until TEDBF prototype is ready and thoroughly tested for production(We know how long testing takes and then the repeated revisions by Armed forces), AMCA prototype won’t be ready any tome sooner. In realistic terms we can expect AMCA by the end of next decade if we do it all alone, if a foreign MRFA jet is decided and if that OEM helps on AMCA then we can expect may be 5 years sooner, we also have engine delay on top of that.

How AMCA is evolution of TEDBF(ORCA at least doesn't exit in any files it's just a fantasy), yeah it is true that Tejas mk2 act as stop gape LRU unit between AMCA & other fourth generation fighter but TEDBF is a different fighter just for the needs of navy it is just a fourth generation plane, Navy for now didn't intend to fly fifth generation plane.
