EODAS(or das) IS NOT EOTS. Can't you discriminate the differences? I never say there is a EOTS on j-20.
J-20 is a pure air-control fighter, not like f35 that is a multifunctional fighter can deal with surface targets.
EOTS that locate on lower hemispherical of f-35's airframe, its main function is obviously a suface tagates sensor system. J-20 do not need that.

I have to post a pic of f35 to explain where EODAS(or DAS) windows on f-35 is.

Isn't it a bit early to start fitting out the prototype with EOTS?

Unless the flight tests actually started a year or two earlier than we all thought.

Skywatchter,

My thoughts also, very early.

Tomluter,

Do we really know that the J-20 is only going to be used for A2A? It is rare to design a A2A fighter with no ground or surface attack capability. The F-22, EF, Rafale, and Pak-FA are all primarily A2A but all have or will have some A2G capability. I would expect the same from the J-20. Have you heard otherwise?

**Tomluter** · 02 May 11,, 18:39

As I know, j-20's only purpose is A-A ,so far at the least.

There are not any evidence can prove fully version of EOTS system test or research in China.
But there are lot sources of EODAS. Even some sub-system of it have already served on fc-1 fighter(a initial distributed-infrared-sensor), actually it is some kind of test and verify, few people noticed that before. EODAS is a combination system including sensors,computer,software, and helmet display system. J-20 can make those together to a final version EODAS,is not a surprise at all.

FC—1的导弹逼进告警系统采用分布式综合光学孔径成像系统，使用4个光学孔径完成对水平360度、垂直± 40度的覆盖，(F一35多一个专用前视和一个专门的下视光学孔径)。这套系统尚未在西方第三代战斗机甚至第三代半战斗机上装备，法国“阵风”有类似系统，采用非常成像体制、3孔径扫描器件，技术水平稍逊一筹。导弹逼近告警系统一般和雷达告警系统交联，系统会主动对雷达告警方向进行高精度重点观测，一旦发现有发射导弹迹象，就会立刻将导弹的准确方位告知飞行员，甚至可以对导弹轨迹进行跟踪，通过光学角度三角计算判断出导弹的大概距离。成像体制告警系统可以在告警的同时将危险方位的视频信号在多功能显示器上叠加显示出来，有利于飞行员判断。其软件进一步开发后，还可以实现对一切威胁目标的自动视频显示，避免因人工智能不足的误判和漏判，同时也能很大程度上避免敌机的偷袭。从越南战争到海湾战争，大多数空战的结果都是攻击方在对手不知情的情况下从飞行员视野盲区得手的。有了这套系统，传统盲区将不复存在。现在还不清楚FC一1这套系统的开发程度，从其座舱使用大面积液晶显示器来看，很明显将会有较多的视频显示，可以把几个不同的区域视频放到一个显示器上集中显示。这套系统可以极大增强战斗机的生存力和近战能力，这对未来空战显得非常重要。

and again, I seriously doubt whether some of those red tagged components on the frame are components of an EODAS..

a fundamental understanding of angles of reflection, capability intent is being suspended to make a case for a capability where even a cursory look shows that flush fitting objects with a minimum of "approach" cannot possibly perform an EODAS role let alone EOTS

even if one were to be generous you cannot honestly state that that the flank components forward of the cockpit area are array modules. angles of coverage are wrong, placement is wrong.

Those look like bazooka woofers someone would have in a car.

**Skywatcher** · 02 May 11,, 23:05

Maybe those 'panels' are flight testing instruments?

That was my first reaction; they look like some high-end quadrophonic stereo system, complete with a serious amplifier.

You guess it! Actually, That is a mini-HIFI for cellphone ;-)

Today,J-20 flew twice. one hour each flight.

1, Side weapon bay (suspected) were opened up.
2, The landing-gear were retracted in flight.
