J-20 5th Gen Fighter Thread VIII

Self-explanatory.

I find it very interesting the J-20A/S variants feature darkened ventral RAM and lighter dorsal RAM... intuitively, countershading should be the opposite: lighter underside to meld into the sky, and darker top side to meld into the ground.

Any ideas why they did that?

What you said is only true during the day. During a night attack scenario, planes should be dark on the underside to blend with the dark sky.

I think there is no longer as high of a focus on WVR for the camos as PLAAF expect engagements between even LO fighter aircraft to be held over hundreds of kilometers. As long as it is not something that sticks out (bright orange or pink) it should be fine.

Makes you wonder if there is any relevance for electro-optical guidance. Probably nothing signficant though.

Electro-optical sensors are not limited by the lights visible to human eyes. It can detect lights of much wider wavelength.

Full-spectrum detection can be achieved by using multi-sensor array or a spectrometer that combines different detectors optimized for specific bands.

It’s always about infrared with electro-optical guidance…

Infrared is just infrared, no? Electro-optical is everything from UV to IR, including the visible spectrum.

Electro-optical sensors are more resistant to ECM, although not immune. Other than flares, there remains the issue of the ECM generating powerful enough interference signals electronically across different IR bands at a long enough distance. Using many IR LEDs won't do.
