J-20 5th Generation Fighter VII

Inst said:

Now, I'm seriously asking for too much here; a tailfinless J-20 is something I've wanted to see for ages, but...

Say the engines get moved to where the rear ECM housing is right now. Extend the wings slightly to the rear to connect into the former ECM housing. Add a triangle for ECM between the current engines.

That'd basically be my "strike J-20", i.e, a J-20 with enough weapons bay capacity to carry both heavy interception missiles like the PL-21 as well as ALBMs in the Kinzhal or DF-21D class.

Here it is, the J-20 Stealth Strike Fighter. I must admit this was tough to do, as seen it's as not smooth as I wanted it to be.
Engines farther apart hypothetically had made more space for belly weapon's bay area.. Possible set backs, due to engine repositioning the Y-duct intake is gone, the starboard PL-10 missile bay probably shrunk if not eliminated and must be put into somewhere else. Also If this is to be a strike fighter variant, this jet should be dual seater. This configuration reminds of F-14 because of the big rear gap..

The strike variant of J-20 might best be discussed further here:


I've already replied to some thoughts you've proposed in that topic.

话说21号大黄鸭17年9月19日中午展翅高飞以后，军工兔终于长长的舒了一口气，好歹这才是真正的鳖版花冻机啊，以前那些鸭子用的都是军工兔精心改装过的毛熊货，换了不少自己的东东，但结构没变，性能提高了个位数而已。可以称之为兔子用自己的实力改进的俄毛花冻机，勉强算小半个国产吧。兔子有自己的梦想，没有山寨31。太行改装团队一直在按部就班忙碌，首飞到今年拿奖，也证明了A类大鸭子的即将参军。
14吨*2的推力带着大鸭子散步都是一马赫以上只是小菜一碟，重要的是突然发现鸭子肚子里有的地方没排上用场？咋办呢？不行就填鸭呗！加两个蛋？没问题！亲，要不再加个座？NO,NO.NO,我是A，加了就成2B了。就这样吧，过几天大鸭子们就要走了，去哪儿我不知道，这几天成都阴雨连绵，今天下午难得晴空万里，鸭子们都在扑腾呢！
小鸭子还在继续孵化中，大鸭子的新产房也修好了，紧挨着卫校，大门朝土龙路，有内部道路直通鸡场，什么四条线？扯蛋，今后大鸭子都会出生在新产房，等小鸭子不下蛋以后，会装修鸭舍，接着孵化大鸭子。别问我是怎么知道的，看门的大爷告诉我的，我贿赂了他一包大前门。
最近局势吃紧，军工兔们也忙啊。但是鸭子们也不是一天两天就能养大滴，急也没用呀！扩大养殖规模也有周期啊，这不，鸡场那头又在搭建鸡窝，呵呵，明明住的是鸭子，还叫鸡窝，真搞笑，兔子是不是有病啊？两个五联排的，钢构都成型了，就是不知道青羊城管会不会强拆，毕竟成都是个国际大都市，搭这么多鸡窝鸭棚会影响市容市貌的。30多个违章建筑很可怕的。
对了，文家场派出所什么时候改名叫蔡桥派出所了？在它面前玩单反那风险可是厕所里打灯笼--找死。还是用我的OPPO吧，不过也没用，纳米图，自嗨一下得了。万恶的132，修那么高，那么长的围墙，真羡慕那些住在青羊工业园三楼的同志们。
好了，不胡说了，再过一会儿溜出去，争取能去西门上，看看我心爱的大鸭子还在扑腾没，尤其是她那性感的小屁屁，不知道什么时候扭起来！

Big duck = J-20, duck is chinese for canard.
Big yellow duck = that one J-20 that flew with yellow primer paint
Little duck = J-10

Overall take according to this rumour:
The first production run of J-20 is powered by AL-31, although this author claims it has been modified somewhat by China which result in some minor performance improvements.
The prototype J-20 in yellow primer paint is in fact a prototype J-20A, powered by two WS-10 of some sort, totalling 14 tons of thrust each. It's not clear if J-20A will have TVC nozzles at this point. Twin WS-10 allows supercruise. In addition this resulted in increase in size of the main weapon bay which allows the J-20A to carry six PL-15. Rumours of a twin seat version is false. The rumours of 4 production lines for J-20 is false, instead they will be built at a new facility which is nearly ready. Once J-10 production ends their production line will also be switched to J-20.

Take this rumour as you will

WS10 is about the same size as AL31, how would just that change allow 6x PL15?

That is easily the most brow-raising claim there and threatens to discredit the whole article. However, if it had truly happened, then I imagine that the WS-10s were custom revised so their their support equipment (fuel lines, inputs, wiring, perhaps even the braces if new advances in material strength allows) were shifted and directed more to the sides to make more space in the middle so the bay could be expanded slightly. I still have great doubt, though...

Unless they're talking about the slimmed down, folded fins "PL-15" built specifically for J-20 and any other future fighters with internal bays, there's simply no way the J-20's bay can be extended enough to fit 6 current PL-15s. The original J-20's bays looks like it can barely squeeze 6 PL-12s even with folded fins. The PL-15 have larger diameter but shorter wingspan than PL-12. Even if WS-10 custom fits with wiring, fuel lines, and gearbox arranged to extend the main bay, take a look at pictures of J-20 bays. There's just hardly any room left. The only solution is to slim down the missiles as much as possible without taking away range and fold the fins.

There is no chance to make the WS-10 slimmer and as such to increase the size of the bay. As such I rate the whole report as highly unreliable

Does J-20 have any air to ground or antiship weapons yet?

But this was discussed ad nauseum ... each time again with the same result: There si currently not enough space for a 3rd PL-15 in each bay, period!
As such there is also no need to open up this can of worms again.

Wait so there's two smaller bays in the weapons bay that can only take 2 missiles each? Why not design it simply as a single bay and fit 5 missiles into it (from what I'm seeing on photos I think 5 PL-12 missiles can be crammed into there. 6 is just impossible.) As for PL-15 missiles I suspect it will be carried by fellow J-16s staying behind the front line of combat and fired when notified by the J-20s or AWACS. Or maybe they will be carried by UCAV drones as some sort of "loyal wingman" setup.

Because you need a latchpoint to hold the bay doors closed I think
