Little Flying Dragons Of China

Also fun, and something Americans really don't talk about enough, how China hacked Lockheed Fucking Martin and stole ALL THE FUCKING BLUEPRINTS to build the F35. Jason man, why not post pics of the J31 or whatever they calling it now. It's the F35 with twin engines. Lockheed admitted the hack. And China turned it into a flying product in very fast time ....

Actually the J31 is MUCH closer to the YF-22 than the F-35. The only part that seems to be lifted from the F-35 is the intake design.

 

 

If anything, DSI intake is one part they do not need to lift, if they actually did any lifting. Chinese had been tracking DSI development since the start -- they actually modified an J-7 with DSI to test the concept. FC-1/JF-17, which uses DSI, is developed after X-35, but is in service before F-35. J-20 uses DSI, so does J-10B/C. All three implementation looks different in shaping and details. If anything, the implementation of FC-1/J-17 is closest to F-35, event that is different in details. J-7 tech demonstrator and FC-1/JF-17 actually predates so called hack, so I don't really see how you can call that a copy.

Maybe, could be parallel development. It does kinda sound like China's really going hard on the espionage though, something to consider. https://wikileaks.org/gifiles/docs/10/1079309_-eastasia-china-us-ct-tech-china-based-hacking-of-760.html

Or/also could be economic warfare. If the F35 doesn't sell enough, the price will be higher, and fewer will be built. Fewer American fighter planes is good for China. Instead of shooting them down in hot warfare later, they could be destroying hundreds or thousands by using espionage and market underpricing today. How to sell more? Make yours look the same, have comparable capabilities, and cost 30%. Hey, why not instill the fear that it's a compromised system, as well?

 

Genius. Genius. Genius.

The FC-31 V2 is the second version of what was called the J-31.

 

The first image came out within last couple of months. The next two and video are a little older, maybe April 2017. There are other pictures which are late 2016 would be my guess.

Why not stealth the missile?

 

Wouldn't work, or at least it wouldn't work as well as you'd want. Total RCS is more than just the RCS of the clean airframe + the RCS of the missile.

 

Unless the aircraft was designed ahead of time with an appropriate recess to tuck the weapon into (like the AMRAAM slots on the underside of the Eurofighter Typhoon), or a big flat spot that the missile happened to snug up to, the missile would have to be on a long pylon. For counter-intuitive reasons I won't get into, short weapons pylons actually create more drag than long ones, so this pylon is going to need to be sizable and have a fair amount of side area.

 

Well, that's not good, because pylons are usually vertical, and wings are usually horizontal, so that pylon and the wing are going to act like a corner retroreflector when viewed from the side. This will increase side aspect RCS enormously.

 

OK, so the side-aspect RCS is totally screwed by external ordnance, but say we only care about the front. It's still OK then, right?

 

Nope.

 

Radar waves tend to reflect off of interfaces where the conductivity changes suddenly. So, obviously, the leading and trailing edges of the wings (and this is why designers are so anal about planform alignment), but also access panel lines, landing gear and weapon bay doors, et cetera. There's a reason all those little panels and doors are sawtoothed and angled on stealth aircraft. So, the interfaces between the stealth aircraft and the weapon pylon, and between the weapon pylon and the stealth weapon are going to act as radar reflectors unless they are treated and angled appropriately.

 

Finally, radar waves can do some funky stuff that could increase RCS in ways that are hard to predict without fancy software. Incoming radar waves might have just the right resonant frequency to bend around a piece of ordnance and echo back to the emitter, or the tube between the aircraft and the ordnance might act as a wave guide and cause greater returns.

 

So, in general, external ordnance can be considered to de-stealth stealth aircraft even if the ordnance itself is stealthy.

Is there any source on how many H-6Ks are in service? Or H-6s in general for that matter. I was under the impression the oldest aircraft were being retired (most of them were not particularly capable, even the 'M' versions, compared to the 'K' with turbofans).

60 would be a lot more than I would have thought. I thought the entire H-6 force was rough 120 machines, but it must be much larger unless older variant are being retired as the K comes online. I had heard once before that the production rate was a dozen airframes per year, but I think it must rather higher. I wonder what the total production run will be? I would have thought 100-200 total.

There's a new version of the H-6 coming out, apparently soon, called the H-6KH. Is said that first flight was in 2014.

Two model images in the spoiler and the usual blurry and top-down teaser view image.

It looks like there's a ventral targeting pod and a pair of outboard jammers of some kind. Do any of the articles list the changes to the new model?

 

I find it fascinating they still are producing new builds of an aerodynamic shape that debuted over half a century ago. Avionics wise, I'm sure its very modern and as cutting edge as they can make it. In terms of the airframe, it inferior to the B-52 or especially the B-1 in pretty much every measurable way.

If they keep making more of them, it might be meant as a sort of work horse meant to get lots of anti-ship missiles in the skies. With all the tech and gizmos, it'll probably make it good enough for their intended role if in great enough numbers. They still have the H-20 bomber program which is supposed to become their so-called B-2 equivalent.

I think there is always a utility in even very basic platforms with large payload and range. The basis mechanics and engineering of large subsonic aircraft is a mature technology with very little prospect for improvement.

"If it isn't broken, why fix it?" or something like that.

It definitely is intended as an anti shipping platform as one of its primary purposes. It has six hard points for either super sonic AShMs or else long ranged sub sonic land attack missiles; these are its primary armaments. They already have enough of them to be effective as an anti shipping platform; even a dozen would still carry over seventy missiles. It retains the top speed and RCS of its ancestor Tu-16 though, so it better have an escort or operate out of fighter and SAM range.

The H-6K uses Russian turbofans. I suspect the answer is much more 'this is the best we can do right now'. For all of the talk of the Chinese being ten feet tall, they are just now building their first MPA (based on a Russian design with US help in pressurizing the airframe IIRC) and their first strategic airlifter (which looks very much like an Il-76). They have achieved success in producing some weapon types but are still generations behind in others. They've been playing catch up for decades and had a decimated engineering and education base due to the Great Leap Forward and Cultural Revolution. I think people underestimate how hard its been for them to establish their technological base and how focused it had to be to get where they are now.
