So what is J-20 solution to reduce RCS when trying to fire its weapons ?

 

This design will allow weapons to be extended into the slipstream (hence allowing passive seeker track) while the weapon bay doors remain closed.

Whenever possible a given mission loadout, all weapons are stored internally for obvious reason.

That includes AAMs, which unlike bombs, usually can only be fired after the missile is outside the weapons bay.

 

 

That also means the stealth advantage will be compromised momentarily with the missile, launch rail extended outside, and bay doors wide opened....All acting like giant radar reflectors as the pilot try to acquire seeker lock.

 

AIM-9 extended from side weapon bays. F22 has 3 compartments for internal storage.

RSAF or DSTA? You machiam a staff member at MINDEF.

Could be cost per aircraft balancing targeted fleet size. Or, China could have previously entered into deals with Russia committing x number of Su. Just my guess.

Think china ald expressed interest on su35 many many years ago, india too

Well, China also already got J-16 that is operational. Su-35 is supposedly 4+ gen.

 

J-20 is supposedly 5th gen and already operational. J-18 is supposed to be V/STOL.

 

Although F-22 was built in the 90's, it is fifth gen.

Nth wrong with acquiring foreign fighter jets. China will study the strength to improve their weakness on the j20

Stealth or reduce radar signature is the main criteria for 5th Gen?

Never say got what wrong. But study 4th gen plane to improve 5th gen plane ?

 

 

 

Should be one of the primary criteria. There wasn't much of a competitor so F-22 was shelved for a while since the 90's.

J20 isnt perfect yet just like f35 when first launched. Some experts said engine not up to expectation

If China got J18 and J20 why they still need to buy Su-35 ah?

Deal was signed in 2015. Presumably as a backup if J20 fails.

 

Good to have variety in the fleet too..

The current engine is only an interim engine, notice the cone shape trusters which does not reduce radar signature.

 

The engine they are developing are supposed to be more powerful and more efficient and also reduced radar signature.

China have a very very big copying machines .....

 

They brought a fleet of SU 35 from Russia and in 5 years time, they will have 250 of them ... [sly]

Taken from wiki

The exact characteristics of fifth-generation jet fighters are controversial and vague, with Lockheed Martin defining them as having all-aspect stealth even when armed, low-probability-of-intercept radar (LPIR), high-performance airframes, advanced avionics features, and highly integrated computer systems capable of networking with other elements within the battlespace for situation awareness.[1]

Often wonder why they can't just reverse engineer and copy design of another proven engine.

 

But have heard from someone that the problems faced is more in the area of metallurgy / materials.

 

Currently the experienced engine manufacturers are only in USA, Russia, Europe. Even Japan is not quite there yet.

Even f35 was experiencing fire in their engine. I think its not easy to produce a perfect engine

I've read an interesting article that the USA purposely leaked some fake classified design details on the F35 to China when they knew China is trying to get the design blueprints. If the article is true, then I wonder how much of the J20's design was already compromised right from the onset. :D

Nearly one year on, J-20 has gone into mass production phase regardless of the WS-15 status.

Interestingly,  SCMP published  its article only  2 month after the 1st known F-35 crash, which led to fleet-wide grounding with fault blamed on the PW engine.

Then in Apr 2019, within 6 months of the first crash, another F-35 from Japan Self Defence Force  went missing over the Pacific ocean while on training.. Part of the wreck was fished out but rest of the plane, its FDR and pilot were never recovered.
