There has been conflicting reports on the J-11D; some say it's a reduced RCS version while some say that it is simply a minor upgrade of earlier aircraft.
Can you shed some light on it?

Currently the exact upgrades on J-11D is still unclear. However since it has been compared against F/A-18E, which, in addition to AESA, does have a limited stealth capablity. Therefore, a J-11D without any stealth measure can hardly be considered a real match to F/A-18E or F-15SE. Limited stealth does have its value, otherwise Boeing and GD were just wasting their time and money, weren't they? ;D So, if J-11D turns out not having any stealth upgrades, there has to be a follow-on J-11E design which will have.

So it's reasonable to expect the J-11D to have stuff like conformal fuel tanks, canted vertical stabilizers, etc, then? |

The chance of J-11D having those fancy stuff is about 50/50. If not it would be an F/A-18C+.

Any opinion on this article? 超大资讯证实歼11D预计在2014年首飞，属于空军立项的短平快项目。 pupu日落说过11D项目早就存在，因为11B、BS出现的问题，11D曾经被束之高阁。目前重启11D项目，明年首飞，进度很快。同为三代半重型空优战斗机，大面积引进苏35的说法和快速研制11D的项目，必然有所冲突。兔子未来三代半重型空优战斗机的布局有点扑朔迷离。 1. 歼11D与歼20、粽子、10B、16无论在时间上和定位上都无冲突，从11D牵扯其他国产战斗机的讨论没有必要。不要扯功能重复，因为三代半重型空优战斗机对兔子不可或缺；也不要扯服役时间晚，因为到2020年，兔子都还有大量二代机和三代退役机需要替换。笔者认为，歼11D研制成功与否和实际战斗力，按道理只和引进苏35的时间和数量有关系。 笔者认为兔子在2015年引进一到两个团的苏35应急，如果研制顺利，到2018年后空军换装歼11D形成三代半重型空优大机群。如果11D研制不顺利或者性能不达标，继续引进苏35作为主战装备，11D可能被压缩甚至砍掉。（航电升级版11B，进度应该可以保证了，但是对苏35的替代性弱了，如果苏35好买，偶估计空军还是希望引进一定数量苏35的） 2. 空军立项研制11D，并且进度飞快，如果不是为了谈判苏35虚晃一枪（可能性不大），那至少说明空军对601和沈飞有信心，他们可能通过11B的问题和15、16的研制，已经基本完全攻克27系的结构和气动问题，对改进航电、材料甚至隐身结构有信心。这个是长期困扰CDER的裤衩问题。（超大更新主帖，11D是11B的航电飞控升级版，没有气动和结构的改进，这样看11D研制服役难度不大，601和SF的研发能力也没有面临新的大幅度挑战） 3. 11D形成高性能最大的障碍还是来自于发动机。由于众所周知的原因，11D用毛发的可能性极低。最大的可能性选择是太行B，然而太行今年好像在某新型飞机试飞过程中又出现双发停车的问题。不过幸好11D的定型应该还有几年时间，这给动力成熟提供了一定的时间窗口。不管这么说，发动机将会是11D形成高性能的要素中最大的拦路虎。 4. 歼11D的研制，无论如何对空军引进苏35的谈判应该有很大帮助。pupu爆料说苏35谈判非常艰苦。（上航电升级版11B，也许说明购买苏35的难度比预想中的更大） 5. 歼11D的定位应该是美帝研制的沉默鹰，三代半加局部隐身设计。与苏35相比，应该隐身性能和BVR能力更强，由于发动机原因，机动性和近距格斗能力更弱。（超大主帖改变，11D只是11B的航电飞控升级版，看来11D和苏35还有不小的差距啊！） 6. 兔子未来的空军配置方式越来越接近于美帝 四代重型空优战斗机：歼20vsF22 四代中重型多功能战斗机：粽子改vs肥电 三代半重型空优战斗机：歼11D/苏35vsF15C改进型 三代半中型空优战斗机：歼10BvsF16改进型 三代+多用途战斗机：歼16vsF15E；歼10CvsF16C/D 现役三代战斗机：苏27sk、歼11A、歼11B、歼11BS、歼10A/AS。 盼星星盼月亮，等待2020年，空军三代四代全系列战斗机格局形成的那一天。。。 |
