Re: Jh-7 thread

hmm, I originally thought YJ-63 was just HN-1, which is the first generation of China's LACM (with about a 600 KM range) and guided by GPS or whatever. After reading some of the stuff on it recently, it definitely looks like it's a TV guided missile. My main question right now is how YJ-63's CEP compares to that of KH-59M. It certainly has better range and possibly larger warhead (it would be similar if it has the same warhead size as YJ-62).

Re: Jh-7 thread

can we stop calling the HN-2/3 the DH-10? That's just a term some taiwanese ethusiast coined, and the TW media picked up.

Hard to say. China considers DH-10 to be its second generation LACM. So who the hell is the first? X-600 is China's first LACM prototype, launched in 1995.

On the YJ-63, the CEP should compare with the Kh-59ME. Suffice to say, TV guided munitions is the most accurate ever you will find. Probably less than a meter of CEP. If you rate munitions on accuracy based on guidance system, it would go like this from top to bottom.

1. TV guided munitions
2. Laser guided munitions
3. GPS guided munitions
4. INS guided munitions

The things is, #1 and #2 are not fire and forget weapons. The difference between TV and laser guided munitions isn't much, the accuracy for both is such there is no practical difference between the two. With TV guidance, you don't need a painter on the ground or aircraft; simply said once the weapon has identified the target through its camera, and the officer authorizes the launch, it can manage on its own. It is however, fickle on weather conditions, which is where the superiority of GPS guided munitions comes in.

Hi Guys:

For what I've read about JH-7s, its specifications are low in all aspects. i.e The Spey engines are sub-power. Since China has got Su-30s, do you think it would eventually abort the JH-7 program? :confused:

Re: Jh-7 thread

Some new strategic stand off weapon successfully tested on the JH-7A. I bet it's a land attack variant of the YJ-83.

Why they choose JH-7A comparing with Su-30MKKseries?
well, I really do hope what Crobato posted is correct. It basically says JH-7A has become a strategic platform. It says that it can carry LACM. I guess that the LACMs could be nuclear capable.

As for why JH-7A over su-30? JH-7A has better precision strike capability than Russia due to the slowness of the Russians in delivering the Sapsan pod. Also, JH-7A has the capability to both deliver Russian and Chinese missiles and PGMs. Considering that su-30 is used as a bomb truck in many ways in pla, JH-7A can do the same at a lower cost. Obviously, it doesn't have the manuverability of su-30, but it doesn't need to for the job that it's given.

经过多年不懈的努力,中国军工终于把“飞豹”打造成了名符其实的空中利器,使之成为中国海空军航空兵的主力战机之一。贝贝可以直截了当、明白无误地告诉军友们:中国飞豹已经走上了系列化发展的轨道。
saying that jh-7 has become one of the main planes in pla
  受中国航空工业基础的限制,基型飞豹性能不甚理想,只有一定数量装备中国海军航空兵。外媒认为飞豹虽然名为歼击轰炸机,但实际上充当的只是对舰导弹攻击机的角色。由于飞豹的性能与中国空军的要求相差甚远,因此没有取得中国空军的入伍证。
the basic Jh-7's capability is not the greated. some people think of it as fighter-bomber, but it is mainly used for carrying AShM. Due to JH-7's capability, it was rejected by plaaf
  在基型机的基础上经过数百项重大改进的新“豹子”(外界称其为JH-7A),已于年前横空出世,入役中国海空军航空兵,这可以说是中国歼轰机发展史上的一个里程碑。同时,中国军工应用业已取得的成果对先前装备海航的老豹子进行了升级改造,期翼能够接近新豹子的战力。我们欣喜地看到,最先列装飞豹的海军航空兵某团,已经具备全天候远海作战能力。新“豹子”的改进主要体现在机体结构、航电系统、机载武器系统等方面。特别值得一提的是,新豹子在机载武器方面有了很大提升,不但外挂点增加,载弹量增大,而且外挂武器的选择性更加灵活(由所执行的任务决定):先进的空空导弹;各种对地/海攻击的精确制导武器(兼容部分俄制武器)和特种吊舱,如国产和俄制空射反舰导弹、反辐射导弹、对地导弹、激光制导炸弹,等等。有报道称,中国正在研制类似老美的联合攻击弹药(JDAM),研发成功后也必将率先装备飞豹。
The improved JH-7A entered planaf. at the same time, it made a lot of improvements from the previously just naval jh-7. the new jh-7 has the capability to conduct all-time long distance sea missions. The main changes are the plane structure, avionics, missiles and such. In weaponary, it's improvement is huge. Not only the hardpoints have increased, but payload alos increased. The external weapon selection is greater, advanced aam, different anti-surface and anti-ship precision guided munition including domestic and Russian Antiship missile, anti-radiation missile, anti-surface missile, LGDBs. Also, rumours are that China is developing something similar to JDAM to equip on JH-7.
  中国空射陆攻巡航导弹早已研制成功并装备部队,这已经是公开的秘密了,什么“红鸟”(HN)、“东海”(DH)绝不是空穴来风。此前媒体曝光了轰六改进型巡航导弹载机。《航空世界》2006年第2期透露,西飞已经为飞豹量身定作了专用的“战略武器挂架”,贝贝估计这种“战略武器”应该是空射远程陆攻巡航导弹。蛋蛋有了,挂架也有了,那么还差什么呢?这是否意味着可以执行空中战略打击任务的鸡鸡也有了亦或正在研发之中呢?
air launched LACM have already been inducted. no longer a secret. one magazine revealed that SAC has introduced strategic hardpoint.
  好的,那我们姑且就围绕着“空中战略打击”这个话题来聊聊飞豹的改进改型吧。
  
  此前,有的军友提出疑问:飞豹要想承担空中战略打击任务要受到作战半径和外挂武器重量的双重限制。呵呵,好家伙!说到点子上了。创造源于问题。问题提出来了,就不愁找不到解决问题的办法。贝贝以为这也正是中国军工们要考虑和解决的问题。
  
  从公开的数据来看,飞豹的最大外挂武器重量为6500千克,经过改进的新豹子的载弹量远远要超过这个数字了,因此新飞豹承担空中战略打击任务外挂武器重量应该不成问题,并且新豹子的机体结构还得到了加强。飞豹的作战半径为1650千米,承担空中战略打击任务够用吗?这就要看要打击的目标在哪儿?有多远?再者说,战机只是一个高度机动性的空中武器平台,要想扩大空中战略打击的范围,可以通过对飞机平台和机载武器两个方面的改进来实现。随着空射远距精确制导武器(如巡航导弹、联合攻击弹药等)的发展,现代空中战略打击对战机作战半径的要求跟从前相比已经大大降低了。这是其一。其二,要想从根本上加大飞豹的作战半径可以通过空中加油来实现,——这对于中国军工来说并不是什么难事。此前互联网上曾经出现过一幅“受油型”飞豹的结构图,贝贝以为那不是一张出自军事发烧友之手的业余作品,而是很有些来头的。
from open source, jh-7's maximum payload is 600KG. the improved new jh-7's payload should be greater than this. operating radius is 1650 km. Is this enough? the, a lot of bs after that.
  有了“受油型”豹子,那么由谁来给它空中加油呢?有的军友会说,那不是现成的吗?轰油六呀!还有我们外购的俄制伊尔-78加油机,用不了太长的时间就会入役中国军队。但是从飞机维护和空中编队等方面来综合考虑,最好研发伙伴加油机——“加油型”飞豹,可以跟具备空中战略打击能力的“受油型”飞豹同场部署,大部分配件和维护设备可以通用,执行空中战略打击任务时空中编队更容易组织和协同,目标小,速度快,加受油程序也可以大大简化。“加油型”飞豹除了装载足够的燃油和空中加油设备以外,还可以配备自卫用的空空导弹和相应的火控系统。这样以来,“加油型”飞豹完成加油任务后,还可以滞空一段时间承担必要的护航和警戒任务。
so, there is JH-7 with IFR, talked about using H-6 and il-78 tanker and also buddy to buddy refuelling.
  有了具备空中战略打击能力的“受油型”飞豹,有了作为伙伴加油机的“加油型”飞豹,但这个空中战略打击编队似乎还缺少点什么。对了,那就是执行电子战任务的“电战型”飞豹!就由它充当编队的电子“保镖”,为编队开辟电磁走廊,对敌实施电磁压制。
  
  我们索性把以上三种型号的改进型豹子称为“飞豹三剑客”好了。“飞豹三剑客”一飞冲天,所向披靡,管叫它什么鬼、什么寇,统统灰飞烟灭!

Re: Jh-7 thread

It looks to me as if it's pretty much between Su variant and JH-7 for main srtike platform, which can render J-10's ground role to a secondary CAS at best. How come PLAAF is still pushing for JH-7 when they have whole slew of technologies that could be used to turn J-10 into a good wild weasal platform. Is it that the radar on J-10 has to be modified greatly?? Already 100or so j-10s have rolled out and We haven't seen any ground munition on it.

What do you guys think will this JH-7 development have effect on J-10's ground role?

Re: Jh-7 thread

I have no doubt that the J-10 will one day carry LGBs and designators. Heck Q-5s are already doing this. But anything beyond that is a question mark.

It looks for me now that the PLAAF/PLANAF has a doctrine that longer ranged missiles like standoff LACMs and AshMs can only be equipped on two seater aircraft. One reason is the second officer acts like a weapons and radar management officer and offload the work burden from the pilot. Another reason is that the PLA probably distrusts that such weapons are left to the discretion of a single person and that the weapons officer also doubles as the political officer. (Note the project that lets single seat Q-5s use YJ-81s was scrapped long ago).

Thus, don't expect the J-10 to be used in more surface attack roles until you see more of the twin seat version around serving more than just OCU training roles. Likewise the same logic applies to the single seat J-11B, not until we see a twin seater version of the same.

So it looks like the JH-7A's future is secure at the moment.
