Chengdu J-20 5th Generation Aircraft News & Discussions

.
All those examples are really just to simply say Chinese 4th generation fighters cannot detect J-20 at any meaningful range. Even when the range is short enough to detect and trace, they cannot get lock on target. This is really what is meant by those statements. To let everyone know 5th generation truly is much superior to 4th.

If radar and IR guided missiles can't acquire lock on stealth aircraft at all, does it tell you that stealth aircraft must have guns then? If its aircraft radar & IRST, they should be able to track stealth aircraft within dogfight range below 5 miles but effective hits probably reduced compared to conventional fighters.

There is a lot behind the 17:0 ratio.

- Were both sides supported by AWACS and ground radars?
- Did J-20 have its radar reflectors on?
- Were the losing side flying with J-10A, J-11B, J-10B, Su-35 or J-10C? There are huge variation in performance.

I find the description "新型改装战机" (a new modified fighter jet) interesting, does it referred to a J20 with new engine?
你很难想到,陈鑫浩驾驭这款新型改装战机飞行时间刚过100小时。
This almost certainly means the J-20 equipped with WS-10. Or if we are going to be even more speculative, it could mean the J-20 with WS-10 TVC, which was said to go into production in the second half of the year.

There is no way that he could’ve gotten 100 hours of it was a WS-10 J-20. They only went into production this year and we don’t know if they’ve equipped any of the combat brigades.

Then it was not the WS-10 TVC then, it was the standard WS-10 equipped J-20s, which would make more sense too.

I think it was a normal J-20 with AL engines.
But why would it say modified then? A modified J-20 can only point to a J-20 with WS-10 engines given our current knowledge of the modifications done thus far. An AL-31 J-20 would hardly constitute a modified J-20.

You guys misinterpreted the article. 改装 in the context of the article does not mean modified aircraft but newly equipped aircraft.

There's no such thing as radar reflector. If the J-20 is stealth, its body is laminated with stealth coating layers of materials along with its slippery shape that radar can't detect beyond visual range at least over 5 or 10miles.

He is talking about this. Of course they exist.

There's only positional gps tracking system that US stealth aircraft could switch on to inform its position but not appearing on radar.

The EMCOM 1-5 on F-22 and F-35 is not about turning on stealth but modes/action that determines how stealth it will be. For example, EMCOM 1 is to turn off radar and internal load only using IRST and IR guided missiles with total radio silence & all sorts of emitters off. EMCOM 2 if not mistaken is sharing radar with AWACS or other aircraft. EMCOM 3 is partial radar on with intermittent off, EMCOM 4 is radar on and EMCOM 5 is attack mode (BVR range) with bay open to launch AMRAAM or with external load.

Unless the J-20 is fitted with extra deflectors that can be activated then it makes sense coz stealth layer is passive system built in the aircraft itself. Like your car suspension is part of passive safety whereas your car ABS, stability control are active safety

Yes they exist. They're call corner reflector, mounted yo amplify radar signature for ground control and preventing true RCS from being seen by competitors during peace time.

This I remember now. Even if this is not turned on, the aircraft built in stealth materials good enough to divert radar waves away which means IAF Su-30MKI can't detect a stealth aircraft at more than 60 miles away, it just won't appear on HUD & MFD at all. The active reflector defense helps when enemy is within closer range especially when the stealth aircraft is banking exposing its larger surface area.
