Indian Air Force Derides Alleged ‘Stealth’ Capabilities of China’s J-20 Jet
By Arthur Dominic Villasanta | Nov 05, 2016 10:11 AM EDT
IAF realizes full well the importance of acquiring a fighter aircraft with stealth features and that's why the Rafale, which has "special stealth features," was acquired from France, said Air Marshal SB Deo, Air Officer Commanding-in-Chief Western Air Command (WAC).
WAC is the largest and most important Air Command of the IAF. It consists of 16 Air Force Bases (AFBs), and is responsible for aerial defense of North India. It controls 21 squadrons, of which 13 are jet fighter squadrons.
The Air Marshal believes the J-20, which was had its first public reveal at the Zhuhai Air Show last Nov. 1, is no cause for concern since Rafael also has stealth features.
"The radial cross section of the aircraft (Rafale) is significantly smaller for an aircraft of that size," he said.
"There are many other features too which I would not like to disclose at this stage."
Air Marshal Deo pointed out the J-20 has stealth features only at the front and not in the rear. This means the J-20 is not a true stealth fighter in the same class as the F-35.
"It is important to maintain stealth while using your radar equipment, while opening your bomb bay doors to fire and ensuring how a weapon can quickly come out of the rails and go out. I do not know how far this aircraft is stealth," he said.
He also said it will be some time before the J-20 is operationally fielded but the IAF is prepared for its arrival.

The Indian Air Force (IAF) is unimpressed by China's Chengdu J-20 "stealth" fighter jet, echoing a growing opinion the J-20 isn't a true stealth jet in the same mold as the Northrop Grumman F-35 Lightning II.
It also points out its new Dassault Rafale multi-role fighters also have stealth capabilities that remain secret but are present in this French-made jet. India has ordered 36 Rafales from the plane's maker, Dassault Aviation.

Isn't is funny, Russian 117S has problem on their PAF-KA and now they have no problem selling an up-rated version of AL-31F engines which has the same thrust as 117S to China?huitong's site now has AL-31F-M2 listed as J-20's engine.
He also has the thrust at 14.7t.

My mind is boggled.

I believe the engine used on J-20 is a hybrid of WS-10 core and AL-31 design.
@Deino
Inner not outer. Sorry, ... ...
How do you know if ChengDu DSI < inner surface structure > on J-10B and J-10C are similar ?
Since when do the Russians have issues with their 117S, which is in fact not the engine on the T-50 but on the Su-35?
You again mix both engines (T-50 uses 117, Su-35 uses 117S).
That simply does not make any sense. Following Your own claims China has a matured WS-10 design with all specifications reaching or even surpassing the AL-31's specifications. So if that alleged WS-10B or G as You call it so often is a design - including the nozzle - superior to the Russian engine, why should then an AL-31FN-nozzle be mated to a WS-10 core? It simply does not make sense, since an engine is always a complete and integrated system. You cannot simply take a RD-33 nozzle and put it on a F404 or vice versa, You don't mate a French M88 nozzle with an EJ-200 core. that does not work.
Only to make some fun with us, who are still discussing that matter ?
Deino
You claim its from me? Since you do not agree me, that means WS-10 is not matured and PLAAF has the incentives to make a domestic engine suits their need which works better that included modding the design of WS-10 into WS-10X with influence of AL-31F. It doesn't matter its not pure WS-10 or whatever. End of the day, its not imported Russian AL-31F engines but 100% domestic made engines.
