Counter USA?

One statement is: "The program started in 1986,[1] to counter new fourth generation fighters then being introduced by the USSR (namely, the MiG-29 and Su-27)". Someone changed it from USSR to USA, which does not make sense. During 1980s, U.S. and PRC joined in effort to counter USSR. China may not have trusted US completely, but China did have a serious fallout with USSR. In the recent years China and Russia relationship has improved a lot, but that all happened after USSR collapsed. Ch2000 05:54, 11 April 2007 (UTC)

And the events of Tianamen Square were the trigger of the stall of U.S.-PRC collaboration. --Henrickson 20:54, 11 April 2007 (UTC)

Talk about conspiracy theorists, wouldn't make more sense that they simply "developed" it? 24.89.245.62 16:02, 21 July 2007 (UTC)

Specifications

Captions from CCTV 7 are apparently revealing some stats on the J-10; I'm not sure if these are official or not.

roll rate: > 300 degrees

Instantaneous turn rate: > 31 degrees

highest speed at sea level: 1450 KM/h = mach 1.18

service ceiling: > 20000 m

G-limit: +9G/-3G

Can reach mach2.0 with 3 fuel tank + 4 AAMs

Can reach a maximum speed of mach 2.34 with nothing loaded

In comparison: F-16 can barely touch mach 2.0 with nothing loaded and su-27 can only reach mach 1.72 with full load of missiles.

range:

for long range air superiority mission with 3 external tanks + 2 Pl-8/2 PL-12 - in hi profile, combat radius is 1110 kM

for interception mission with 1 external tank + 4 PL-12/2-PL-8, in hi profile, combat radius is 900 km.

Not including in-flight refueling

J-10's maximum subsonic unstable degree? 10 degrees (apparently this is higher than that of Typhoon).
Also the New designation used by CCTV and Chinese literature for the twin-seater is no longer J-10B but instead J-10S

"apparently this is higher than that of Typhoon", There you said it. These figures are highly doubtful. En51cm 03:09, 13 February 2007 (UTC)

False Information

Not that anybody seems to care, but another comment by me. According to Global Security, which is listed as a source, the J-10 can do Mach 1.85, and yet the article claims that the plane can do M2+. If there are no objections, I will change this. --The1exile 17:00, 6 January 2006 (UTC)

Global Security is wrong. They just took the Lavi top speed and assumed that it would be the same for the J-10. However, the some of the design features of the J-10 such as the variable geometry inlet indicate that it should have a much higher top speed than the Lavi. The dimentions that they give for the aircraft are also based on the lavi, so they are probably a bit off as well.--Todd Kloos 19:57, 6 January 2006 (UTC)

Ok then, thats enough to knock Global Security of the external links page; providing misinformation is not what Wikipedia is about. --The1exile 20:14, 6 January 2006 (UTC)

chief designer

According to the Chinese press, the chief designer is Song, Wencong (宋文骢), not Yang, Wei. ——Nussknacker胡桃夹子^.^tell me... 19:50, 3 January 2007 (UTC)

Serious references wanted

Such sentences in the first paragraph without serious references seem to be a personal conjecture, and could be considered to delete, Wikipedia should not be ragout of all kinds of rumors:

A series of press reports in February 2007 indicated that the aviation community now strongly suspects that the J-10 was built in part with secret Israeli assistance, specifically obtained from Israel Aerospace Industries, using design knowledge gained on the now-canceled IAI Lavi fighter[citation needed], as well as by illegal copying design elements from a U.S.-made F-16 Falcon fighter secretly (and illegally) donated by Pakistan[citation needed]. As a quid pro quo, Pakistan is now the only non-Chinese user of the J-10.

——Nussknacker^.^tell me... 17:27, 11 February 2007 (UTC)

Pakistan Air force is not a user of J-10

I also do not think PAF should be listed as a current user of J-10. Even if the order is true, there is no official confirmation from Chinese source, and PAF has not begin to operated it. BTW, I will try to update the J-10 wiki entry with some referrences in the coming weeks. I might also restructure the entire thing. Hopefully some people could help me proof-read and edit the thing when I update. Ch2000 10:00, 21 March 2007 (UTC)

ACM TANVIR MAHMOOD AHMAD is quoted as saying 18 F-16C/Ds, 150 JF-17 and 36 F-10A would be join PAF. However I could find an official statement on it. china did have the F16 and possibly some data on Lavi as claim but the level of useful is questionable as the J-10 is quite different from both plane; afaik, it is only a POV by some and not widely supported because of a lack of evidence.

J-10 Image

There used to be an image of a J-10 taken from the side that has somehow disappeared. Who removed it and could someone at least replace the image that was unnecessarily removed? (Psychoneko 22:06, 9 June 2007 (UTC))

The images were removed because they were supposedly not licensed properly, meaning the person who deleted them was unsure if they could be used legally on Wikipedia. The only image remaining image is a sunset shot, and it does not show the aircraft very well. We'll just have to wait until someone else supplies legally-usable images. - BillCJ 22:45, 9 June 2007 (UTC)

1979

However, a Chinese magazine (zh:少年科学画报, ISSN1000-7776) published in June 1979 showed a boy holding a model of J-10. [4] The picture showed that the project began long before 1979.

How sure are we about this? The source itself cannot be confirmed in English, and the plane in the picture is significantly different from the current J-10 design -- it lacks the forward canards, and the wings are clearly not in the delta wing configuration. The air intake is very similar, but could it be from another plane? Ham Pastrami 14:41, 4 October 2007 (UTC)

The J-10 was originally designed in Isreal, not China. The US thought the J-10 would be competing in the international markets with the F-16, therefore under US pressure the development was halted. In return the Isreali air-force got a discount rate for US air technology. Against the US wishes, the designs were sold to China. —Preceding unsigned comment added by 195.157.154.249 (talk) 13:03, 24 October 2007 (UTC)

On the section concerning Israel

The persons quoted in the section are Israeli citizens, and their remarks are rather direct and strong for this topic. I removed the word "Possible" for that reason. The J-10 is a Chinese Lavi, in both content and appearance.--Jackkalpakian 00:41, 14 November 2007 (UTC)

The actual content of the section as it is now contradicts what you wrote. The Chinese are claiming that J10 and Lavi are unrelated. The claims of similarity between the two aircraft are (entirely valid) speculation by some reputable sources. No hard evidence is presented on this site, or any other source which I have seen. Thus, "possible" is best. It is also possible that you are just reverting based upon spite, in which case, don't let my anti-spitism stop you. Wee Lion (talk) 15:18, 22 November 2007 (UTC)

Actually, you need to set your nationalism aside, Wee Lion, the Israelis are admitting that they helped China -- you are substituting Chinese histriography for the truth, and you are also absolving Israel from its obligations to its allies. Admission is enough, the Israelis are openly saying they helped, and also the planes look alike, what more??? China deserves credit for reviving the Lavi, no mean feat. --Jackkalpakian (talk) 17:16, 28 November 2007 (UTC)

There is no doubt that Israel sells military technology to China. I believe there is also ample confirmation that J10 contains Israeli technology. The question is whether any special expertise was shared, from the Lavi project or from elsewhere. The only evidence for this, beyond speculation, is the visual similarity between J10 and Lavi, which is shared by a number of other planes such as the Eurofighter Typhoon. I would be especially interested to see any evidence that J10 contains American technology obtained from Israel, which is what you are insinuating, though poorly. At any rate, my point about spite still stands. Wee Lion 14:55, 30 November 2007 (UTC)

Let's have a vote!

To everyone: I noticed lately that the word "Possible" has been removed and re-added to the "Israeli participation" section header over and over again. Some of us want that word to stay, others want it to be gone.

Now, to prevent this issue from becoming an endless revert/edit war, let's all make a single, final decision about it. Vote now to the following question:

Should the word "Possible" be included in the section header of "Israeli participation" or not?

A) Yes, include the word "Possible" in the header.
B) No, do not include the word "Possible" in the header.

You can vote starting now. All votes will be compiled one week from today, on December 08.

I vote: B. --Henrickson ^{User talk | Contribs} 08:39, 1 December 2007 (UTC)

• It's probably best to discuss other possible options before just accepting those two. I think we can come up with headings that better reflect the paragraph's content, but that will be less prone to revert wars. - BillCJ 08:53, 1 December 2007 (UTC) (I see you standing in the fire. And I won't forget you.)

I vote B--Jackkalpakian (talk) 21:47, 5 December 2007 (UTC)

Vote results

OK, it's already December 13, and here are the results:

	Vote counts	Percentage
A	0	0.00%
B	2	100%
Total	2	100%

The outcome is: B) No, do not include the word "Possible" in the header.

It is interesting to note that the original section header used by the editor who wrote that section was "Possible Israeli participation?", with the question mark at the end. He already knew that the word "Possible" was going to create conflicts. A revert war began when someone removed that question mark. --Henrickson ^{User talk | Contribs} 23:33, 13 December 2007 (UTC)
