Specifically for the purpose of detecting stealth aircraft, the Chinese have developed and implemented the ASEA radar operating on JY-27A meter waves. To detect hard-to-detect aircraft, it uses the resonance phenomenon occurring at the point where vertical and horizontal elements of the airframe are joined. VHF waves can cause the excitation of a standing wave or other form of electromagnetic oscillation between the ballasts, which increases their radar signature. In addition, if the VHF wavelength is close to the dimensions of specific aircraft components (e.g., vertical and horizontal stabilizers), they can become effective radar reflectors, increasing the reflection of the signal towards the radar.

Bit of a worry it seems if they have figured it out.

This is to the best of my knowledge a known effect of specific wavelengths of radar and one of the reasons people refer to designs without vertical control surfaces as “broadband stealth”. A number of large surface based radars use this wavelength, though the only airborne example I am aware of is the E-2D.

This has been well known for a long time. Russian and Chinese VHF surveillance radars were developed (since the early 2000s at least) with vertical polarization that seek resonate off the vertical stabs since they are ~ 1.5 to 2.5 x wavelength. Detection does not equal engageable track however. The push now is to cue other sensors and fuse the picture to build a engageable track. This is why there is a push to tailless designs for 6th gen.
 
Well, metadef.fr is often the powerless victim of its own binge drinking attitude toward anti-US subjects. At a time when the Alliance got seriously wrecked by recent poor diplomatic choices, it should not surprise anyone that those voices are to be heard again.
Call it a polarization effect.
 
Defense Updates put out earlier today listing five reasons why India may not chose to buy the F-35:


On February 13 , when PM Narendra Modi met US President Donald Trump, he offered India the fifth-generation F-35 stealth fighter.

Trump said, “Starting this year, we’ll be increasing military sales to India by many millions of dollars, we’re also paving the way to ultimately provide India with the F-35 stealth fighter”The realism of Trump's F-35 offer remains uncertain, but there's no doubt that India is actively seeking new fighter jets.

This development comes against the backdrop of F-35 participating in Aero India 2025 where it stood just meters apart from the Russian Su-57, which has been officially offered to India.While we have argued that the Indian Air Force may avoid Russian Su-57 in a previous video, linked above, the F-35 is also not a very suitable option for India for a few very specific reasons.

India possessing and not decommissioning their SA-21 Growler batteries alone would make such a deal with the US a non-starter.

It's known for many decades if not more.
It's used by nations concerned about stealth for decades, with more of them being added over time(some grew technologically capable over time, others simply grew concerned).

China is doing more of things already known, better. Because they both can do it, and can afford to do it.

I.e. flying L and UHF bands, oversized optical mirrors. No magic.
All effective in appropriate situations, all have counters or major inconveniences.
 
The Su-57 is a heavy fighter, the F-35A is a medium fighter.
The cost for a foreign customer is comparable - $ 150 million apiece.
Combat effectiveness:
air-to-air
Su-57 - 1.6
F-35A - 1.0
air-to-ground:
Su-57 - 1.87
F-35 - 1.0

Flight hour cost: Su-57 up to 15,000 dollars / hour, F-35A - 32,000 dollars / hour
The Su-57 is manufactured in India, except for engines. F-35 production of all components in the USA.
Combat use of the Su-57 without restrictions, F-35 only with the permission of the United States.

I'm always very amused by how you quantify your little pronouncements of combat effectiveness and whatnot

If there is no corruption component, the choice is obvious.

There seems to be several errors. Su-57 in air to air is closer to 1.19 and F-35A just a notch above 1.45. In air to ground, the Felon comes in at slightly below 0.8, while the F-35 achieves 1.89. Of course I'm comparing the CTOL F-35A.

Curious if S-71K/M can at least to some degree make up for it in the future. Though it's certainly a far more expensive way to do things.

It's great to see the US operating with allies! Not something we can take for granted anymore.
