India’s electronic warfare goals are shifting rapidly.
As I study the Tejas Mk2 programme closely, the recent RFP from ADA for an indigenous broadband radome with an integrated polariser stands out as a moment that defines intent, capability and confidence.
This article explores why this radome matters, what it means for the LCA Mk2 EW Suite, and how it positions India within a changing geopolitical and technological landscape.
A journey that begins with a single component
I have followed this programme for years.
Every update reveals how India is shaping a fighter designed for complex, multi-spectrum combat.
The radome may look simple to the untrained eye.
But to anyone familiar with modern EW systems, it is the bridge between raw electromagnetic reality and actionable situational awareness.
This is where the story begins.

Why the radome drives the EW system for LCA Mk2
The radome influences how clearly sensors detect, decode and track threats.
It is the first layer of interaction between the aircraft and the invisible battlespace.
Core functions influenced by the radome
• Clean signal entry
• Reduced waveform distortion
• Better accuracy for radar warning receivers
• More reliable electronic support measures
• Higher DRFM deception efficiency
• Stronger tracking in cluttered environments
The integrated polariser adds fidelity to this system.
It shapes incoming signals so the EW suite can classify hostile radars with higher precision.
This places the LCA Mk2 EW Suite in its development path
This RFP signals a new stage.
The EW suite is moving past simulation and into integration.
Three pillars shaping the EW roadmap
1. Multi-band awareness
The aircraft must recognise threats across wide frequency ranges.
2. Faster reaction cycles
The suite must respond before an enemy radar completes tracking.
3. Open architecture scalability
Future sensors must integrate without structural redesign.
The radome enables these foundations by ensuring pure signal flow before any processing begins.
Technical depth that shows the scale of India’s ambition
Broadband radomes require mastery in material science and electromagnetic transparency.
ADA’s specifications reflect this level of ambition.
Key technical expectations
| Capability | Description |
|---|---|
| RF transparency | Clean multi band signal transmission |
| Polarizer integration | Better accuracy and classification |
| Lightweight composite | Reduced drag and improved agility |
| Thermal resistance | Stability under intense aerodynamic heat |
| Structural durability | Integrity during high G manoeuvres |
These design elements show that the EW system is built for modern air combat conditions.
A story of indigenous confidence and technological independence
As someone who tracks India’s defence policy evolution, I see this RFP as part of a broader narrative.
India is moving away from foreign dependency in high-sensitivity technologies.
Radomes are tightly controlled globally.
Few nations export them without limitations.
Indigenous capability ensures:
• Freedom to upgrade
• Predictable supply chains
• Custom designs for IAF doctrine
• Lower long-term cost
• Stronger defence manufacturing ecosystem
This shift is driven by strategic necessity rather than sentiment.
How does this strengthen the Tejas Mk2 in real combat scenarios
The Tejas Mk2 will become a frontline medium-weight fighter.
Its effectiveness will not be defined by speed alone but by what it can sense and counter.
Operational advantages
• Earlier threat detection
• Better long-range classification
• Stronger self-protection
• Improved BVR survivability
• Enhanced multi-threat handling
• Control over the electromagnetic battlespace
A better radome improves every one of these outcomes.
The geopolitical context that makes this upgrade urgent
India’s neighbourhood is undergoing rapid military modernisation.
This includes the deployment of new radars, integrated air defence systems and long-range sensors.
Regional shifts influencing the radome requirement
• China’s expansion of multi-band early warning radars
• Pakistan’s induction of AESA-equipped fighters
• Increased activity in the Indian Ocean Region
• Growing electronic intelligence missions near Indian airspace
India’s fighters must be built to counter not just current systems but next-generation threats.
This radome upgrade fits directly into that strategic trajectory.
India’s aerospace industry gains a long-term advantage
This RFP builds industrial capability that goes beyond one programme.
It supports next-generation platforms and future design cycles.
Likely contributors include:
• DRDO labs
• HAL composite divisions
• Indian private defence MSMEs
• RF specialised startups
• Advanced material engineering firms
This strengthens India’s long-term technological base.
Why this upgrade is essential for future Indian fighters
The Tejas Mk2 is not the end of the story.
It is the foundation for the AMCA, TEDBF and unmanned combat systems.
A mature radome ecosystem ensures:
• Faster prototyping
• Local testing
• Lower cost iterations
• Custom EW loadouts
• Indigenous maintenance cycles
This is the kind of ecosystem every major air power must build.

Conclusion and My final perspective
After analysing this development, I see the radome RFP as a clear indicator of intent.
It shows India wants to shape its own EW future, not adapt borrowed technology.
The LCA Mk2 EW Suite will be defined by the quality of this radome and what it enables.
From clarity of detection to the speed of counteraction, this component strengthens every layer of air combat readiness.
It is not just a technical upgrade.
It is a statement of confidence in India’s capability to build fighters tailored to its own geopolitical reality.
