ADA AMCA - Advanced Medium Combat Aircraft

[Rajput Lion]

Only 10dB RCS reduction

*More than* 10dB RCS reduction

Anyways here is something interesting. IIT Kanpur has developed a transparent meta-material that is going to be used on our future/upgraded fighter jets that also absorbs RF waves between 90%-98%.

Link: Protective Layer for Microwave Metamaterial Absorbers


Here are some interesting quotes from the research paper:

• The new invention can be applied directly to optical transparent windows, making them capable of absorbing over 90% of incident electromagnetic waves at microwave frequencies.
• This invention has great potential in defense for stealth technology and in commercial sector for reducing electromagnetic radiation in buildings and houses by deploying it on windows.
• The metamaterial absorber remains robust even under harsh environmental conditions and rigorous handling, without compromising its microwave performance over time.

Some more:

Notably, coating the absorber led to a significant increase in absorption efficiency within microwave frequency range, rising from 95% to an impressive 98%.

So we've developed stealth Paints, Composites, Laminates and even meta-materials than can absorb well over 90% RF waves(in various frequencies), almost upto 98-99%.

It's really remarkable how fast we've caught up to the West. Our AMCA is going to be one very very stealthy bird. Just sort the engine FFS and we're all set.

Yes, it may seem "remarkable" on paper. However, when it comes to delivering a solution to the military, it is just a decade late.
