Indian Air Force says it can tackle Chinese J-20 jets

[Ultima Thule]

Even chinese have s400 so they must be aware of it's strengths. Also S400 has a limited range leaving lot of room for Chinese jets to cross borders. Against stealth fighter only a stealth fighter can be a deterrent.

What IAF gonna shoot J20 with? Bows and arrows??

now that's a sensible/reasonable post buddy

 

[Crystal-Clear]

feel good post . J-20 is an overdose for india & they knows it . indians have a habbit of portraying " all is well" ( what they did in Doklam incident) but when the reality strikes they start begging for peace and bilateral trade etc ( which happen after they find out masive Chinese presence at Doklam).

almost every indian has a powerful weapon: Mouth Gun

it can shoot down J20 easily

The new engine is required for supercruise and TVC not so much for stealth. A majority of stealth factor comes from reducing the RCS through the shaping of the aircraft, composites, and RAM coatings...on that front J20 isn't pending any upgrades like in the case of its engines.

A new engine is required for stealth. The current engines are not stealthy. And without the engine having stealth designed into it, the aircraft will be highly flawed.

So it doesn't matter if India has Barak 8 or not, the only thing that matters when it comes to stealth is u have to be able to detect the aircraft on radar(ground/AWACS/etc) in order to be able to engage it.

The Barak-8's radars will be able to detect the J-20 in current conditions because the aircraft is still a WIP.

The aircraft doesn't become flawed just bcuz u say so...what aspect of the engines "non stealth" are u talking about? It's nozzles? That's about the only part of the engine that's exposed bcuz reportedly J20 already has S ducts...in which case that's a rather minor factor bcuz again the MAJORITY of the reduction in RCS(and hence stealth) is achieved through shaping, composites, and RAM coatings. Adding stealth nozzles would make an already stealthy J20 more stealthy. So unless u have some evidence/facts to present about how J20 is somehow not stealthy as a whole platform...do share. Otherwise have the decency to say that these are just ur own hollow claims.

Shaping the nozzles only reduces edge diffraction, which is not the biggest source of returns from engines. Engines are a huge source of returns due to cavity resonance. The insides of the engine have to be designed for stealth using blockers and other devices. The engine requires IR treatment from the ground up. None of these have been done on the WS-10 class of engines.

The airframe itself may be stealthy, so the aircraft will have low RCS from some angles, but the engines themselves have to be changed if it is to become a proper stealth aircraft. Having partial stealth is good enough for an aerial fight, since you are exposing only your low RCS side to the adversary, and IAF aircraft are yet to be modernized, but when it comes to SAMs, you need all aspect stealth. The Barak-8's radars are way too advanced to be defeated by half-assing stealth on a fighter.

Read up on S ducts before u start throwing in words like cavity resonance. The very purpose of s ducts is to hide away the engine from radar. This only leaves the nozzles as the non stealthy part of the aircraft which u just admitted urself..."isn't the biggest source of return"

How does IR signature of the aircraft help ur radar detect it?

So you are saying 5th gen engines are unnecessary.

Air defences also have IR detectors.

was hoping indian news would reveal "India recently acquired top secret alien ufo technology"

 

[Taimoor Khan]

Come on people, you missed the most important bit in the article .

“Cost is the biggest worry... We will be posing some questions to the Russians on the S-400 delivery and deployment in Iran, Syria, Yemen and even Pakistan,”

We been hearing round the clock non sense from Indians about their acquisition of s400 will make PAF redundant. It will be funny if it's Pakistan which acquire it before India.

So you are saying 5th gen engines are unnecessary.

Where did I say that? Don't put words in my mouth. Of course the new engines are needed for more thrust, thrust vectoring, and stealthier nozzles.

I'm just pointing out that ur opinion is flawed. A lack of stealthy nozzles on the J20 isn't a big enough factor that would make it light up on radar. This is where u started off ur argument...
"And the J-20 can be defeated because the current version is not complete. It still requires a lot of work, especially a new engine."

So again u have been unable to provide solid proof backing up ur argument about how without those new engines the J20 can be defeated as if the rest of its stealth factors somehow don't matter.

what kind of stupid air force is this ?

You haven't understood. Just like how untreated inlets are bad for an aircraft's stealth, an untreated engine is also bad due to the same reason. It's a big hollow cylinder that shoots all the radar signals back to its source.

The WS-10 is not a 5th gen stealth engine. Nozzles have nothing to do with it.

The J-20 is not all aspect stealth yet.

Looks like u still haven't read up on S ducts and u r just arguing for the sake of argument...if u did read up on it u would stop saying that bcuz the J20 does have S ducts.

The WS-10 is not a 5th gen stealth engine.

It doesn't matter bcuz the radar doesn't get to "see" the engine...again read up on S ducts

Nozzles have nothing to do with it.

Yes they do...there is such a thing as stealthy nozzle and non stealthy one. In fact that's the only thing u can use here with ur argument about J20's engines being non stealthy...if it wasn't for the J20 engine nozzles being non stealthy, ur argument would have no leg to stand on.

The J-20 is not all aspect stealth yet.

Yes...like I already mentioned the nozzles. That would make the rear aspect slightly less stealthier as opposed to the sides and frontal aspect. In any case the overall aircraft is still STEALTHY.

Man don't be in fools paradise,j20s threat is real and never ever underestimate your enemies.
