So Tom has made a quantum move over Jerry's stealthy tactics. Now Jerry must do something.
no lol, the photonic radars still rely on RF waves for detection. The thing that changes is that fact that theyre generated using lasers and fibre optics which give insane precision. This allows them to have insanely large bandwidths which like 11Ghz at almost the same time. It also allows radars to see stealth and hold track unlike the previous where you could see the jet but it would be intermitent blips not a continuos track which makes it hard to get a lock on. It also has near 0 phase noise to Low probability of intercept.
it wont make stealth obselete but it will push the range back to around 200-300ish kms where there is plently of time to launch a missile at the jet and not get hit. Again this is only after complete development if that ever happens at all.
Nah man, I didnt concentrate much on studies in my school days and relied on some web course which got sold to my parents for entrance and hence I funked my entrance and wasnt allowed to repeat and got into a tier 3 private college, however I did focus more on studies later and graduated with honours, my professor was a student from NIT and when we were shortlisted some projects for our final project, mine and another group both selected projects related to nanofluids, we had to go through a lot to finish the project because we had to source nano particles from a shop far away from college, test the weight and composition of these nanoparticles in another far away government college with better facilities, buy stuff like thermocuples and other stuff from someone from another state and heat and mold it in a workshop in location, not to mention since I didn't have funds to buy a branded heat sink for our Heat Source(CPU under heavy load), we had to either manually make the Heat Sink from some industry using copper or source the components from China, the latter of which I did and it got stopped at customs and not sent to us, so I luckily meet a guy from a computer hardware store with a youtube channel who knows a fan who talked with him on insta who had a spare system, so I rented the heat exchanger and radiator from him and tested the effiiency under various concentration of nanofluid and compare it between each other along with traditional air cooled methods. The difference in efficiency between both is night and day.You used AlO2 nanofluid in your.... engineering project?Are you in IIT or IISc?
You'll definitely become real Batman 1 day.
Nothing painful about it, just hobby since childhood. Computer/IT guys deal with multimedia in work & presentations, so writing just paragraphs like novels is not my style.
Please don't dig others' past conversations, speak on their behalf, compare them.
In a casual chat forum for time pass, i'm not seeking any support or to ARGUE. Rather DISCUSSION is a better neutral word. Everybody, from students to veterans, journalists, etc can keep their PoV as per their profiles. DoD not consulting us here.
I often wonder how many active members on Indian forums are Indian.
Photonics radar is the preliminary step to Quantum Radars. VHF radars can already detect & track stealth, not as efficiently as desired though so Photonics radars are definitely a step up.
DRDO is conducting field trials this year with the services. If all goes well this could get into mass production by the end of this decade. That certainly boosts the anti stealth capabilities of a nation's ADS.
Moreover these systems won't work in isolation. They'd be part of a larger system of systems involving Space & Air based ISR , ground based radar stations, sensor fusion etc . All put together this can compromise stealth to a great extent blunting the absolute advantage it enjoys today.
Quantum Radars should be the final nail in the coffin of stealth. China's already claiming deployment & successful detection & tracking from 300 kms away IIRC.
Then again with the Chinese how much of this information is genuine & how much is the usual propaganda is hard to say but Quantum Radars is definitely a revolution in the radar family akin to when RF was first used to detect & track planes .
Just a word of advice. Cultivate a sense of humor & learn to be less uptight, be it in the real or virtual world.
Would help you a lot else the world's too full of sensitive souls feeling aggrieved at the drop of the hat . Also encourages anti social feelings as a result in such poor souls .
Leave the world, 1st let's manage ourselves by sticking to forum topics & avoiding philosophical gossip dragging others
. No member here is responsible for those poor soles out there.
5 fingers different.
same humor doesn't work with everyone.At least spare me from such gossip.
You're very informative guy. Let's move on.
yes it is a kind of technique for digital signal processing, instead of taking the input from whole radar the radar is divided in 4 quadrants and input from quadrants is channelized for processing. This processing logic is new.
The Photonic radar will outdo the current stealth technology with ECCM and shape stealth. Conceptually, it's way ahead of the current generation of aircraft. I looked online to see which countries are already developing their photonic radar, and I found some info below.
IMO this technology has a long way to go, especially regarding power management for fighter-class radars and detection range, considering the available power and software integration with your fire control radar during high-G maneuvers, etc. It's great that we're on the right track, but again, quantum computing and quantum communication are going to be part of the 6th generation aircraft.
| Country | Status | Key Achievement / Agency |
| China | Operational/Mass Production | In late 2025, China began mass-producing the world’s first four-channel photon detector (nicknamed the "Photon Catcher"), specifically designed to track stealth aircraft like the F-22. |
| India | Field Trials/Induction | The DRDO (LRDE) developed a fully indigenous photonic radar. Extensive field trials across diverse climates (Ladakh and the Thar Desert) were completed in late 2025, with plans to integrate them into Tejas and Rafale jets. |
| United States | Advanced Integration | Long-standing leader via DARPA and companies like RTX (Raytheon). Recent 2026 focus shifted toward "Project FROSTY," which uses photonic-assisted sensing to see through Arctic interference. |
| Italy | Pioneering Research | Italy’s PHODIR project (Photonic-based full Digital Radar) was one of the first to prove the tech in field trials at the Port of Livorno. Leonardo S.p.A. is currently integrating photonic circuits into its "Michelangelo Dome" defense system. |

Guys, i wanna confirm present specs of AMCA, i guess it got updated recently.
Is the following correct -
Is the following correct -
Dont change anything for now or specifically mark it as tentative, we wont know for sure until the consotium for the AMCA is selected. But yea the specs do look correct
Who am i to change anything, when i'm not connected with any maker.
I'm just comparing AMCA with other jets.The currrent updated specs with F414 engine are ok but AMCA Mk2 with new engine will be 5.5gen then specs will change.

IDK who made it,found it on X, but looks cool
AFAIK, new indo-french AMCA engine will be 120kn. 2×120= 240KN~
Most probably, AMCA will Have MTOW of 30ton-ish. (Like J-35)

The JV engine requirement has been projected around 120-130 KN, probably bcoz some engines have been augmented, like F414 engine of F-18 SH Block-3 has been pushed up to EPE (Enhanced Performance Engine) version with 20% more wet thrust of 117.6 KN from 98 KN.
After tabulating engine parameters whatever i could find of some popular engines like F414-EPE, F119, F135, AL-41, AL-51, WS-15, M-88-TREX, as per some calculations the JV engine in same dimension of F414 has theoretical potential of -
- almost 130KN wet thrust
- almost 84 KN dry thrust.
Ofcourse materials will matter, but as per alternate calculation, at least 120 KN wet thrust should be possible.
Matching engine parameters as per our desire is damn tricky.

India’s AMCA stealth fighter gains high-efficiency intake design
India’s ADA achieves 98% pressure recovery in a stealth fighter intake design breakthrough supporting the AMCA fifth-generation fighter.

India’s AMCA stealth fighter research achieves near-perfect intake airflow efficiency
India’s Aeronautical Development Agency (ADA) has reported a significant advance in the aerodynamic design of stealth fighter engine intakes, achieving performance levels that could strengthen the technological foundations of the country’s Advanced Medium Combat Aircraft (AMCA) programme.The findings, published in the February 2026 edition of the Journal of Aerospace Sciences and Technologies and first reported by ******, outline how engineers have validated a new intake geometry capable of preserving engine efficiency while maintaining the low-observable characteristics required for modern stealth aircraft.
The aerodynamic dilemma of stealth fighter engine intakes
One of the fundamental design challenges for stealth aircraft lies in hiding the engine’s compressor blades from radar.These rotating components are highly reflective to radar waves and can compromise an aircraft’s low-observable profile if exposed.
To solve this, designers use serpentine or “S-duct” air intakes that curve inward, preventing radar from having a direct line of sight to the engine face.
While effective for stealth, the curved geometry introduces severe aerodynamic complications.
In a straight intake, airflow enters the engine smoothly. In a curved duct, however, the air can become distorted as it negotiates the bends.
Disturbed airflow reduces engine efficiency and can lead to compressor stall, an abrupt disruption of airflow that may result in engine failure. Persistent distortion can also increase vibration and fatigue in turbine components.
New S-duct intake design achieves 98% pressure recovery
In their study, ADA researchers, including R. Abilashini and Valliammai Somasundaram, combined wind-tunnel experiments with advanced Computational Fluid Dynamics (CFD) modelling to test a revised intake configuration.The results demonstrated a pressure recovery rate of around 98% at transonic speeds, meaning almost all of the incoming airflow energy was preserved before entering the engine.
For curved intake systems, such efficiency is considered exceptional. Every bend in a duct typically introduces energy losses through friction and turbulence, making high-pressure recovery difficult to achieve.
The researchers also confirmed that the intake remained stable at angles of attack of up to 60 degrees.
In such extreme manoeuvring conditions, airflow normally becomes highly unstable.
However, the team found that the intake lip generates a controlled vortex that guides airflow smoothly through the duct even during aggressive combat manoeuvres.
Improving wind tunnel testing for stealth fighters
The research also addressed another technical challenge: how to accurately test stealth aircraft designs in wind tunnels.Because full-scale fighters are too large for most facilities, engineers rely on scaled models mounted on a supporting rod known as a “sting”. That rod can disturb the airflow behind the model and affect measurement accuracy.
The ADA team developed correction factors to account for this “sting interference”, improving the reliability of wind-tunnel data.
The study also confirmed that simplified or “truncated” aircraft models can produce accurate intake behaviour results when instrumentation is carefully calibrated.
These improvements could make aerodynamic testing for stealth aircraft faster and more reliable.
Implications for sixth generation fighter jets
Beyond the immediate needs of AMCA, the intake research could also support future sixth-generation aircraft designs, particularly tailless or blended wing-body configurations.Such aircraft aim to minimise radar signatures even further by eliminating vertical stabilisers, but the absence of those surfaces introduces new aerodynamic challenges.
Demonstrating that stable airflow can be maintained in complex intake systems without relying on conventional airframe stabilisation marks an important step toward these next-generation designs.
Taken together, the ADA study not only addresses a long-standing engineering hurdle in stealth aircraft design but also lays the groundwork for India’s ambitions in advanced combat aviation in the decades ahead.
Question regarding the prototype, I have asked this before but it's still not clear
Since ADA is giving contracts for prototype components, are the companies already building it as of now such as BEML for cooling system, and will selected partner just do final integration work when it's selected or no physical work is to be done until it's selected?
Iirc it's supposed to be selected this or next month

Some components are already there. Partner/consortium will manufacture the airframe, do integration and testing
