it does seem a bit of a puzzle, so big, yet all this focus on agility.

Could be this be some sort of long range multirole? Seems to be F-111 over again and theres not enough power in china(?) to make it a fighter?
Who says it’s big? It’s long but size in aircraft is determined by weight. The undercarriage shows that this aircraft is about as ‘big’ as a Su-27 or a MTOW of around 30 tonnes a long way from the F-111’s 45 tonne MTOW. The length is clearly for aerodynamic purposes.

Maybe the Canards are just FUD and a prototype will appear without them.
About as likely as removing the wings between a prototype and production version.

If it's a 5th gen. air superiority bird, why the focus on agility? Shouldn't the focus be on sensors, and signals management?
Who said it was a 5th generation aircraft? Signature management is out the window and who knows about sensors but the benefit of the doubt says it will be a long way behind F-22/F-35. Its clearly the kind of plane you build when you can't build a 5G fighter. As fast and as agile as possible with a small, narrow frontal RCS. Same deal as the T-50.

Since when will the intel community claim they were wrong? Not even after an invasion where nothing showed up.
they have and do. some of us don't live in a bubble.


Despite all the claims in the above, not one addressed the issue on the reasons for the F-22 termination.
have you ever worked in an environment where there was no point in contesting a view that the executive were hell bent on doing? Gates fired people for disagreeing with his views of the procurement world and future force constructs.

get real


Gates said what he said. What some tacplanners privately think and what they actually tell the boss in an official report could have been different in this case. That's probably with a conservative plus and best estimate basis. There's a lot of estimates out there and someone will always claim to have predicted the next big crisis.
and when there's proof of a contrarian view it means what? FFS, do you seriously think that the SecDef view is sacrosanct.. Do you want to go back to recent history where SecDefs talked up a non existent threat with the Sovs - where in a number of instances the US had clear delivery and accuracy superiority but kept up the banter?


When the photos came out, some responses came out = fake.[/quote

so what? Ever seen the images of the USS Reagan complete with PLAN flag and chinese writing over the gantry? ever seen the photo of Mao swimming the yangtze?

Gates is not the first to make such claims about official under-estimation. Its not the first incident either. It happened with the ASAT space test, its going to happen with something else in the future. That is consistent with the calls for PLA transparency. Its consistent with decisions undertaken.
what absolute rubbish. again I can point to any number of USAF int officers who talked about ASAT 5 years ago. There's any number examples of overestimation as well.

Putting faith in a claim made by SecDef is just as moronic as kids getting amped up about Chinese AF generals claiming that they will smoke the US in 2 years time.


The chinese appear to be targeting an operational date for the J-20 before 2020. Dorsett may have openly claimed a 2020 operational date and has defended it. But my guess is the official reports are going to be updated.
and yet the initial estimates were about a 2017 IOC with FOC within 5 years

The PLAAF had problems with the J-10 engine. Ultimately they went Russki in order to operationalise it. That delayed the deployment. If they didn't learn from that for the J-20, I'd be surprised. I don't think it will take 10 years from the first flight to operationalise the new jet.
well considering that it was first discussed internally in 2005 and was hitting the net in some specialised sites soon after, then 10 years is looking a little tight.

whats FOC for the PLAAF? How many squadrons/regiments? how integrated with the the force de main? how hooked into their force de main? what training across platforms - let alone services has happened.

I get pretty pi##ed off with convenient comments and where people are more interested in throwing hand grenades in the room rather than accept that the truth is not always on the internet and that the only considerations are whats on the net. That is fundamentally naive at best....Its a convenient strawman at its kindest....

5th gen is not just about sensors and sig management, its also about how the aircraft contribute to the battlespace management mix. sensors and si8g management are just major elements.

5th gen comprises more than half a dozen identified capabilities in some of the RAAF documentation....

Earlier than expected?

My first email traffic on the J20 started mid 2004, in those very first emails and posts the discussions with tacplanner colleagues in the USAF was a first flight cycle of 5 years. we were 6 months too optimistic.

some of the rubbish being written about the US being caught short sheeted is absolute rubbish - certainly not within the community.

don't mistake public media or blog commentary with official commentary.

the first shots I saw of the J20 was 4 months ago, with earlier facsimiles appearing some 12 months earlier.

people need to get a grip. the internet, blogs etc... is not the sum knowledge about this article - and "nobody" was caught asleep at the wheel. I'd suggest that Gates wasn't listening to his own people (due to his F-22 issues) - and thats certainly the case when I look at my 2004 traffic.
Given Gate's original assessment of 2025, I would say he's just giving the media fodder to shorten the life cycle of this story and get journalists off his tail. It's against his, the military's, and the intelligence community's interests to have the media constantly refer back to his original estimate whenever the J-20 becomes visible during its testing phase.

Anti-ship ballistic missiles are launched from land-based ground units, not aircraft. In the future (if the the proof of concept is valid...) then there is the potential for some sea or submarine launched variants as well. Air-launched Anti-ship missiles are another category of weapon all together.

-Cheers
Ahh I see. I misunderstood his comment. I thought he was talking about supposed ASMs being tested on the JH-7s. I would imagine that land based ASBMs don't have to worry about their "loud" signature because they will be flying too fast for an easy intercept, something that you couldn't do for an airbased ASM due to fuel constraints for size reasons.

the lesson for Gates I suspect (and any other politician in the executive) is to avoid "feeding the chooks" ie responding to the press without being prepared.

all these wonderful achievements by china being aired as sudden demonstrations of capability were first getting flagged 5-6 years ago. In fact I reckon that some of the chatter that displacedjim and I had re carriers, asats and the J20 could probably be found on an SP cache somewhere.

“One of the things that is probably true, is we have been pretty consistent in underestimating the delivery … of Chinese technology and weapons systems,” Adm. Dorsett said. “They enter operational capability quicker than we frequently project.”

Willard cited uncertainty and concern among Asian allies over what he called an unprecedented military buildup by China over the last year. He said U.S. intelligence estimates have underestimated China's abilities annually over the past decade.

"They've grown at an unprecedented rate," he said.

You need to separate what they say in reports with what they say in public. When a report cites a change it's usually an official reassessment. What they say in public is merely media strategy to control the pace and visibility of a store.

agree.

Unfortunately, commonsense can be lacking when people blithely quote an internet response and see it as the only professed public view of the executive - and assume that the professed public statement carries the same weight away from the podium

unfortunately commonsense and critical thought also appears to have left the building with the advance of the internet.

I wonder how many times we need to refer to both official US and Sov?russian comments about capability which were subsequently shown to be for public consumption and didn't reflect service "paced" analysis

Insults aside, before the Internet, a certain guy called MacArthur ignored certain public warnings from a guy called Mao regarding a certain place called Korea.

Now 3 top defense officials including the top intel officer saying the same thing. Using the same standard, because certain people on an internet forum think they are lying, therefore we should ignore the top 3 views? Standards and commonsense has imho indeed left the building if I place more weight on an internet forum but I'm merely highlighting the contradiction here.

Just highlighting that thinking that junior officers couched the report to agree with the boss and then agree with claim that the report and public relations efforts are already contradictory is in itself contradictory. Its one or the other.

I make my own value judgements on how much weightage I give to what they have said and I have not stated what these judgements are other than a generalised statement that I think the intel community has been overestimated. Wrt the actual speed of J-20 development, I have merely quoted what Gates has said so far which is they have been blind-sided. I have provided all my citations to back that up. Whether that is true or not, its what they said so that validated my original quote. So far, I have been merely posting to see what kind of responses, the manner of people and the thinking behind the opposing comments. Its illuminating and supports my generalised statement. The view of the intel community at least from the posts in this thread appears to be "god-like" capability. I think that validates my original comment that there's an over-estimation of intel capability. I doubt if many will understand the above. That is not intended as an insult but my perspective of reality.

In simple terms, it is an opportune time to highlight that the "grown-up" way to deal with this is merely to present the facts which is what they have said and agree to let everyone make their own minds up rather than make assumptions which is all I'm reading right now.

Different political systems will have different media cultures and different strategies. When Chinese officials say something the political motive can be different from when a US official says something. Also, context is important. What a country's media directs to another country's political leadership is different from what a country's media directs to its own citizens.

Having three officials say the same thing only implies that the DoD have agreed to what their public position is on the matter and how they will control and handle the story. It says nothing about what they actually think in detail, especially since it's futile trying to put in depth analysis into a media system that operates off sound bites. For that you have to observe official documentation (not all of which are accessible of course) rather than media sound bites. Before you go off insisting argumentum ad populum you need to think about the purpose by which they say what they do. Remember their job isn't always to tell the truth to the media. (If it were Iraq wouldn't have happened).
Just highlighting that thinking that junior officers couched the report to agree with the boss and then agree with claim that the report and public relations efforts are already contradictory is in itself contradictory. Its one or the other.
Not when what they want to communicate to the public is different from what they want to communicate to each other. That's especially the case when there is a shared understanding of this within an organization.

Your observations could just as easily be interpreted to "the defence and intel communities don't want a small story to develop legs and be burdened with a haranguing public media that has the defence jitters, which is exactly what the media is for stories like these. Remember, the media's job isn't to tell the truth either (at least not completely). They're in it for attention and money.
In simple terms, it is an opportune time to highlight that the "grown-up" way to deal with this is merely to present the facts which is what they have said and agree to let everyone make their own minds up rather than make assumptions which is all I'm reading right now.
All arguments require some degree of assumptions (yours included). Some assumptions are more well founded than others. Right now we're discussing about why we have the different assumptions we do.

It appears to have more to do with whether people like the message rather than anything else.

If they like your critical thinking "its well observed, researched and insightful"

If they do not like it its "Tin Foil Hat Conspiracy Theory".

If they like the official line " Its look here's the official line in black and white"

If they do not like it, then "Its just puff for public consumption".

I could say more but will in the interest of good manners I will restrain.....

That's always going to be true to an extent, but I believe there are always real reasons for parsing what an official says to the media.

Well, the official line is the official line and while I am the last person to swallow every word uncritically, it is obviously what we are being wanted to believe and that has to be being wanted for a purpose.

Defining that purpose is the true name of the game...

And that's when your best guess is as good as mine. Everything else is merely circumstantial. :)

Are you allowed to post those identified capabilities? They would give us a real way of evaluating aircraft.

One of the photos I saw was the development team of CAC celebrating after the first flight. It was interesting since the red banner that was hanged on the stage stated "Celebrating Project Type 718 demonstrator aircraft's successful development". It seems the plane has not yet received its "J" designation as of yet. More importantly, I am more intrigued by the use of the term 验证机(demonstrator aircraft). Could possibly be another piece of evidence suggesting that this is not a prototype. I think the guy standing on the right is the chief designer.

Perhaps the most suprising of all is how open the Chinese government has been during the past several weeks, compared to their previous handling of such matters. It may very well be that they were intent on making a statement to its neighbors. Of course, the original photo was taken on what appeared to be a cellphone shot, and others flocked to the airfield later with more sophisticated cameras after it was circulated. This explains where the high definition photos came from. The fact that CAC is located on the outskirt's of China's 5th largest city does not help to keep people out either.

An interesting table I've obtained regarding engines.

Just a reminder, perhaps it is best to limit the amount of political analysis and focus on the plane itself instead. Me no like the last couple of pages.
