How Not To Think About The J-20

Posted by Bill Sweetman at 12/30/2010 10:50 AM CST

Now that the last few skeptics have been converted to the idea that the J-20 is a real airplane, and not the product of a network of Chinese teenage boys armed with Photoshop, the internetz are rife with speculation about the project's schedule, technology and capabilities.

Much of it is both premature and misguided, the result of several basic errors in analysis, politics and prejudice.

The first mistake is "mirror imaging". The Tu-22M Backfire was not a B-1, but the USAF wanted it to be one, because they desperately wanted to resurrect the B-1. The MiG-25 looked like the air-superiority fighters that the USAF was sketching in the late 1960s, but it was nothing of the sort. And just because the front end of the J-20 looks like an F-22 does not mean that it is an F-22 clone.

One problem with mirror-imaging is the unspoken assumption that the other guys face the same challenges that you do. But to take a couple of examples, the Russians in the Cold War never had to worry about a dense, layered surface-to-air missile threat and the US does not face an adversary with a significant carrier force.

A related source of error is an attempt to exploit the appearance of a new Chinese or Russian system to support a pre-existing belief system. That's why people who want more defense spending will upsell the threat, and predict that the new whatever-it-is will be operational next week and in production at a rate of 100 per year, and those on the other side will point to the adversary's primitive technology level, and argue that the new aircraft is merely an X-plane. The right answer usually lies between those points, but more importantly, it won't be found that way.

There's a healthy dose of cultural prejudice behind both errors. Mirror-imaging, in the Cold War and today, is supported by the idea that Communists are unimaginative bureaucrats who can't innovate their way out of a wet paper bag. We found out this wasn't true, on a massive scale, after 1991: for instance, the combination of helmet-mounted sights and high off-boresight missiles sent the US scrambling to develop the AIM-9X, and US spy satellites fly on Energomash RD-180 engines.

China's military engineers and planners have unintentionally reinforced this image over the decades, preferring to upgrade Soviet-era systems rather than developing new platforms. But that tends to obscure the fact that (to take one example) the latest version of the HQ-2 surface-to-air missile bears only an external resemblance to the Soviet V-750.

Since the current military modernization started, new weapons havev been increasingly innovative. The question of Israeli technical assistance notwithstanding, the J-10 does not resemble any other fighter, and the J-10B less so. In other domains, systems like the Type 022 fast missile boat resemble nothing anywhere else (and could that be one reason for the fast-paced ONR/DARPA LRASM program?).

Next question: what does the J-20 look like from a Chinese perspective? Watch this space.

As the author notes, the truth about China's weapon technology and deployable capability is unknown.

What is known however is that China has embarked on a campaign to gain military superiority over the United States and that America appears to no longer have the means nor will to do anything about it. The ace in the hole of course is the US nuclear deterrence, but when the Ascended 0ne talks about being able to “absorb” an attack, it makes you wonder if the US leadership would respond in kind.

Exactly. That thing is so big, how can it avoid radar detection?

If you put up gigawatts of jamming as you attack a force near your homeland, the signal to noise ration is effectively minimized until you are in range to fire/drop your munitions.

In other words, with the right ACTIVE ECM environment you don’t have to be THAT stealthy, just lower your observability.

If the Chicoms were to attack Taiwan or a nearby US fleet, one would expect they would just blanket the RF spectrum with POWERFUL jamming to blind our defenses but also to make their ‘stealth’ weapons harder to separate from the noise.

That is the landing gear cover, not stairs.

Okay. I blew it up to max resolution to see. It still looks huge for an aircraft..........

From Wiki: The J-20 is over seventy feet long and powered by twin Saturn AL-31 engines provided by Russia, which have 32,000-pounds thrust coupled with thrust vectoring nozzles made in China.[2] The J-20 might have lower supercruise performance and agility than an Lockheed Martin F-22 Raptor, but the J-20 has larger weapon bays and can carry more fuel.[5][6] The J-20 has a long and wide fuselage and low jet engine intakes with a forward chine, a main delta wing, forward canards, a bubble canopy, conventional round engine exhausts, and canted all-moving fins.[4] The front section of the J-10 is modelled after the Lockheed Martin F-22 Raptor and the body and tail compare to the Sukhoi PAK FA.[7]
