J-20 and Other News from Zhuhai Air Show 2016

China made it official this week that J-20 is coming to Zhuhai air show. All of this is quite interesting when one compares this to how long before J-10 made its first visit to Zhuhai Air Show. Clearly, China has taken a more confident and transparent approach in its military programs in the past 10 years. At this point, J-20 has started Low rate initial production batches, but has yet to achieve IOC. To that end, AVIC must be confident enough in the progress of flight-testing program to allow J-20 to appear in China’s most prominent aerospace exhibition.

A couple of years ago, PAK-FA had an epic failure when one of the prototypes had fire damage while delivering a flight performance in front of IAF officials. Certainly, the pilots were most likely instructed to put on a show to impress PAK-FA’s largest export client, but the aircraft was also clearly not up to task. The result of that embarrassing incident was extensive delays in the flight-testing program while that prototype was getting repaired. More recently, Russia finally officially adjusted the initial induction of PAK-FA to 2018. It had been obvious for quite a long time that they were not going to make end of 2016, since the fixed up prototype and new prototypes have just recently surfaced. I have not kept up to the progress of J-20 units, but it seems like the first LRIP frames may have already arrived at FTTC. FTTC should very soon start training with this new aircraft. IOC may be achieved by late next year. Of course, engine remains to be a major concern for the J-20 program. It’s still not known at this point what is powering aircraft. It would seem to be a special variant of AL-31FN, but this will be an interim solution until WS-15 is ready. At its induction, J-20 will be quite underpowered.

Aside from J-20, other big-ticket items like J-10B, KJ-500, Y-20, Z-10K and H-6K will all be physically displayed in the air show. Since a real J-10B came, the serial number was finally allowed to show. Maybe after this appearance, China will allow J-10B pictures to be published without the serial numbers photoshoped. Zhuhai air show has traditionally been an occasion for China to show its latest UAV and missiles (many of which are still in conceptual stage). It will certainly be the case again this time around. While we have already seen well know UAVs like CH-5 and Wing Loong-2, we are also seeing new concepts that could very well make their mark in the export market. The latest one we saw is Cloud Shadow UAV which looks a lot like SkyWing UAVs that have already test flied.

Finally, a recent national day parade in Turkmenistan showed that all of its SAMs, missiles, radar systems and UAVs are all imported from China. All of this is quite unexpected since Turkmenistan has traditionally been under the overwhelming presence and influence of Russia. At this point, China is clearly making inroads against Russia in many export markets.

China May have Operational J-20 Stealth Fighters by 2017

The first J-20 squadron expected to be fully delivered by year's end, the China Flight Testing Evaluation regiment will being developing operating procedures, tactics and technical proficiency to bring the J-20 to combat readiness. At this pace, it is expected that in 2017-2018, the Chinese Air Force will have its first operational stealth fighter squadron.

At this pace, it is expected that in 2017-2018, the Chinese Air Force will have its first operational stealth fighter squadron.

The J-20 currently relies on Russian AL-31 series turbofan engines (the powerful domestic WS-15 engine will enter service in 2019-2021), everything else on the J-20 is Chinese; its stealth coating, infrared sensor, powerful AESA radar, are all domestically made.

Development of the WS-15 began in the 1990s. The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012. In 2009, it was known that the prototype was able to achieve 160 kilonewtons (36,000 lbf).

China has about a ten year lead on building and using domestically developed stealth fighters versus other Asian rivals (domestic Indian, Japanese and Korean stealth fighters are not expected to enter service until after 2027). In addition to J-20 and the soon to follow in production J-31 stealth fighter, Chinese plans also call for stealthy drones, bombers and advanced cruise missiles.

China's J-20 and Geopolitical Implications.

The J-20 project has made some significant progress in the past 2 years with the roll out of prototypes 2011 to 2017 to accelerate the flights testing and development of the J-20 aircraft. With the roll out of 2101, what appears to J-20’s first LRIP aircraft, it’s possible that the first batch of J-20s will get delivered to FTTC this year to start the process of expanding flight envelope, testing/evaluating new weapon systems, developing new training procedures and combat tactics for a new aircraft. If FTTC evaluation proceeds well, J-20 may be certified and start entering into service next year. It looks like the project is proceeding a couple of years faster than the original expectations. For this entry, I want to look at how the progress of J-20 vs progress of other fighter jet projects affects regional balance of air power.

To start off, the most obvious threat to PLAAF comes from the vast number of F-35s that will be deployed in the APAC region by America and its allies. Due to defense cutbacks by many Western countries, key American allies in APAC region should not have to wait too long to get their F-35s. If J-20 enters service in the next 2 years, it will enter service extremely underpowered since WS-15 is not yet ready. As a result, I think the initial J-20s will have to carry limited fuel and payload in order to achieve desired flight performance. Until WS-15 does become certified with J-20 sometimes next decade, there are certain missions involving longer range and greater payload that J-20 just cannot perform. USAF and USN’s will have overwhelming qualitative and quantitative advantage in the region against PLAAF in the short term. Even after J-20 enters service in larger numbers later with WS-15, I think USAF and USN’s F-35s will still have both qualitative and quantitative advantage in the region. J-20 probably will have certain advantages over F-35 in flight performance, power and payload, but will definitely be at large disadvantage in stealth, sensors, weapon system and the ability to operate in a network centric environment. Reading Chinese sources, I have often gotten the impression that PLAAF regards F-35 as its biggest threat (even more than F-22) due to F-35’s technical and numerical advantage over what China might field. I don’t think anything from the past couple of years have really changed that.

J-20 and More Thoughts On 5th generation Projects

Most recently, a 7th prototype of J-20 project (No. 2016) appeared and made its maiden flight on September 18th. It’s been 9 months since the last prototype had come out, so this new prototype is a sign that the program has not hit any major stumbling block and was just going through the next iteration in its development. As a refresher, 2 prototypes (No. 2001 and No. 2002) came out and flew in 2011. They were probably the demonstrators of this program. Over 2 and half years later, the 3rd J-20 prototype (No. 2011) came out and was followed by 3 more prototypes (No. 2012, 2013 and 2015). They had some major redesign and changes compared to the demonstrators. So they should be considered the first pre-production prototypes and were probably produced in the same batch. CAC and CFTE have been testing them since that time. I expect that more J-20 prototypes will be coming out in the next few months, since they seem to be building them in batches on this and past CAC project. Compared to the last batch of J-20s, the most noticeable changes have been on the DSI bump and the engine nacelle. The DSI bump looks to be a little larger and people have speculated that some EW equipment may be installed inside. From the relatively few changes between the batches, one can surmise that the J-20 design is more or less frozen.

Indeed, there have already been speculations that the first production J-20s will come out next year to be tested and evaluated by FTTC. While I think that is certainly possible, I think it is also best to tamper one’s expectations and expect some problems along the way. Every 5th generation projects so far have experienced some bumps along the way. The PAK-FA project had fire on one of its prototypes and still has not flown a new prototype since. IAF have continually complained recent years about the technology and progress of PAK-FA. The F-22 and F-35 projects are far more open, so there were many reports of issues along the way. One would expect J-20 to encounter similar issues along the way even if those reports only come out in the rumour mills of Chinese military forums.


With everything that we can see, I think that CAC has been doing a great job with the J-20 project. At this point, I already consider J-20 project to be ahead of PAK-FA in both the design and timelines. In terms of design and technology, J-20 looks to be better configured for stealth from most profiles vs PAK-FA. The next generation AESA radar and the rest of electronic suite are already been deployed J-10B/C and J-16 compared to lack of such Russians platforms. Even the next generation missiles (like PL-10 and PL-15) seem to be further along in development and deployment than similar Russian systems. PAK-FA only seems to be using a more advanced engine at this phase of testing. Considering that the Russians started to research on 5th gen fighter jet in the 80s and first flew PAK-FA a year earlier than J-20, this does not speak very well of Russia’s aerospace industry.

J-20 project
J-20 project

For the past year or two, I’ve read numerous articles coming out of India that complained about the technology, cost and lack of their work share in the PAK-FA project. Since then, there was a fire on one of the PAK-FA prototypes when they were giving a flight demonstration to Indian delegation and have not shown a new prototype since. There have also been numerous online posts about the build problems and quality issues with those prototypes. Now most recently, I’ve also seen a report where India is thinking of pulling out participation in the development of PAK-FA and just buying them straight out of Russia. They probably realized Russia was unwilling to share its most sensitive secrets so they needed to devote more of their R&D resources on their domestic project MCA. At the same time, it also appears that some in IAF is favouring for purchase of more Rafael and less PAK-FA. There are numerous components of PAK-FA project like stealth and propulsion, which are not up to par with the standard established by F-22. If the leap in technology over Rafael is not big, then it makes all the sense to buy the more of the mature platform. Of course, that could also create a disastrous scenario for IAF if J-20 and FC-31 turn out to be much better than Rafael.


China's Super Weapons: Beware the J-20 and J-31 Stealth Fighters

People’s Liberation Army Air Force (PLAAF) of the People’s Republic of China (PRC) has lagged behind the aerial programs of other world powers such as the United States. Now, the PRC has set its sights on producing indigenously designed “fifth generation” fighter jets comparable to the US F-22 Raptor and F-35 Lightning II. Many U.S. officials and pilots suspect that the Chinese have been usinghacked U.S. technology to aid their indigenous development programs. The PRC is also leveraging additive manufacturing technology (better known as 3D-printing) in order to increase speed and efficiency in manufacturing aircrafts and compete with the U.S. The J-20 Black Eagle could be fully operational by 2018, and a second model, the J-31 Gyrfalcon, by 2020. If true, China’s new generation of fighters could have a substantial impact on its ability to either defend what it considers to be sovereign airspace, or to mount an aerial offensive in a wartime scenario, particularly against Taiwan (ROC).

Recent Advances in the PLAAF

Between 1990 and 1992 the PRC purchased 24 Su-27 Flankers from Russia and slightly modified the design to become the J-11 Flanker B+. In response, the U.S. sold 150 F-16 Fighting Falcons to Taiwan. The acquisition of fourth generation Su-27s allowed China’s Air Force to enter modernity, and they have become progressively more capable ever since. In 2010, half of the PLAAF fleet still consisted of jets modeled after 1950s and 1960s Soviet MiG-19 Farmers and MiG-21 Fishbeds, but China’s ability to project air power has increased significantly within the past 5 years. Recently, the PRC and Russia have nearly completed a deal to transfer 24 Russian Su-35 Super Flankers, a potent “generation 4++” fighter, to the Chinese, in addition to China’s scheduled integration of fifth generation technology.

Currently the PLAAF relies on the J-11 as its primary fighter. However, this model is largely unproven. This aircraft is perhaps most recognized as the fighter variant involved in an August 2014 incident in which a single J-11 intercepted a USN P-8A Poseidon surveillance aircraft 135 miles east of Hainan Island. Twice the J-11 came within 50 yards of the U.S. aircraft. The aggressive maneuvering by the Chinese pilot was an example of the PLAAF making it clear that U.S. surveillance is not appreciated within the airspace over its exclusive economic zone (EEZ).
J-31

Fifth Generation Capabilities

Since 2008 the PRC has worked to design and manufacture fifth generation concepts, both for its own use and to sell on a global scale. Two companies in China have worked on designs: the Chengdu Aircraft Industry Group (J-20) and the Shenyang Aircraft Corporation (J-31). Both are subsidiaries of the state-owned Aviation Industry Corporation of China (AVIC). It is likely that the J-20 and J-31 will complement one another when integrated into the PLAAF’s arsenal. The J-20 is closer to becoming operational, with an inaugural test flight in 2011; it is expected to reach initial operating capability (IOC) by 2018. Because both jets are still in prototype stage, their exact capabilities are not certain. However, it is speculated that the J-20 will provide a long-range strike system capable of reaching anywhere in the Western Pacific region, and incorporate a stealth design; the first of its kind in the PRC. In a conflict, the J-20 would likely be deployed in air-to-air combat with the mission of limiting the enemy’s radar coverage and strike range. The J-31 could be a potent complement to the J-20, similar to the planned U.S. partnership of the F-22 and F-35. While the J-20 is expected to possess superior dogfighting abilities, the J-31 will be “the perfect fighter for the PLA to carry out anti-access area-denial (A2AD) strategies in the Western Pacific”. The J-20 is slightly faster, with a maximum speed of Mach 2.5compared to Mach 2 for the J-31. Both sport a combat radius of approximately 2000km (1242 miles).

U.S. officials believe that the J-31 will immediately match or exceed the capabilities of U.S. fourth generation fighters such as the F-15 Strike Eagle and F/A-18 Super Hornet, and could possibly even compete with the F-22 or F-35. But this would largely depend on several factors including the quality of Chinese pilots, the quantity of fighters produced, and the reliability of radar and other equipment on board. In late 2014, AVIC President Lin Zhouming made an even bolder prediction, saying, “When [the J-31] takes to the sky, it could definitely take down the F-35. It's a certainty.” Even if neither of the Chinese fighter jets is entirely up to par with U.S. fifth-gens, they still could drastically change the dynamic of both a conflict with the U.S. or a scenario such as an invasion of Taiwan.

Chinese Firm Unveils New Sensors For J-20, J-31

A privately-owned Chinese sensor company has unveiled a suite of air-to-air and air-to-ground sensors in development for the latest Chinese and Russian fighters.

Wang Yanyong, technical director for Beijing A-Star Science and Technology, confirms that two systems – the EOTS-89 electro-optical targeting system (EOTS) and the EORD-31 infrared search and track (IRST) – are in development for China’s J-20 and J-31 fighters.

Marketing brochures on A-Star’s booth suggest that the J-20 could use the passive sensors to detect and aim missiles against the Northrop Grumman B-2 bomber and Lockheed Martin F-22 fighter, even while its radar is being being jammed by a Boeing EA-18G Growler. It lists detection ranges for the B-2 at 150km and for the F-22 at up to 110km.

Both systems have completed ground testing in a laboratory, and are now ready to enter flight testing, he says. Chinese combat aircraft manufacturer AVIC is considering integrating the sensors on a testbed aircraft, then could decide to test them on the J-20 and J-31, he says. Operational status is at least a year away for both sensors and possibly longer, Yanyong adds.

J-20 Is Very Close To Final Production Version

J-20 No.2015 is very close to final Production version.

J-20 doesnt use Russian 99M2 as most foreign 'experts' and Russia media claimed
it uses improved third gen turbofan, domestic engine.


J-20 No. 2015
J-20 No. 2015

J-20  production phase A wont have WS-15 but domestic improved third gen turbofan, Max 14.3 metric tons thrusts production phase B will be fit with WS-15.


J-20 deployment version will have soft laser weapon, not to shoot down a plane or kill a ground target, but to 'kill' infrared guided missiles.

China's PLAAF Review In Year 2014


This was a particularly eventful year for PLAAF when one looks at the progress of the various new projects. The most noticeable of which is J-20, but this most will look at various other projects too.
Coming into this year, the J-20 project seemed to be a little behind schedule compared to PAK-FA. There were a lot of questions about when the 3rd flying prototypes will come out. Earlier on, we saw the appearance of a heavily modified prototype No. 2011 which first flew in March. As previously discussed, this prototype really transitioned the project from the concept/demonstration phase to pre-production engineering phase. The next prototype No. 2012 appeared in July and had its maiden flight near the end of the month. Most recently, prototype No. 2013 and 2015 appeared in quick succession in the past month and had their first flights. These 2 prototypes have their pitot tubes removed. Speculations have been that No. 2016 and 2017 will also appear soon to join the flight testing phase. With the quick succession of these prototypes, it appears that J-20 may have moved into LRIP. I have in the past compared these prototypes to F-22's EMD phase, which had 9 flying prototypes. Bu in that case, the 9th EMD first flew 5 years after the first EMD. So it seems like J-20 is using a more aggressive flight testing program. We know that there is already a radar testbed testing out J-20's radar and possibly other avionics. So next year, we should see more of the initial prototypes coming out and getting transferred to CFTE for flight test programs. At some point, I think we should see J-20 prototypes starting to using domestic engine options. We should also see J-20s starting to be delivered to FTTC for developing tactics and testing out flight envelopes. But a lot of that stuff really cannot be tested fully until WS-15 becomes available. Despite all of the fast progress by CAC the past year, it's unclear what they will do with the engine problem. The earlier J-20s will probably use an underpowered engine.

The other project that received a lot of attention this year is FC-31, because of its appearance at Zhuhai air show. From what we've seen, it is still in the conceptual demonstrator phase waiting to get picked by PLA. J-20's first 2 prototypes were probably further along than No. 31001, so this project is several years behind J-20. PLAAF have the option of going with hi-lo option of J-20 and FC-31 or J-20 and some heavily modified variant of J-10. The next generation of naval aviation can either go with a naval variant of FC-31 or something completely different. At this point, it does look like FC-31 will be picked up by PLAAF and the official version will feature much changes compared to No. 31001. They will probably have to use some under powered interim option from Russia in the beginning while the domestic option is even further behind than WS-15.

J-10 program was in the background this year, but it may have been the most active PLAAF program. J-10A production and delivery continued into this year. J-10B production finally started at end of last year after a very long flight testing period, but the production level this year has been quite high. Most recently, the 48th J-10B came out. We've seen one brigade of J-10B joining service with FTTC aggressor squad. A second regiment/brigade will also be formed from this year's production. After this first batch of J-10B production, things are a little muddled. We saw a J-10B in primers with factory number 201 that came out at end of last year with some minor changes from the first batch of J-10Bs. Chinese bbs have speculated that this is the first of J-10C variant. The big speculation is that J-10C will be using AESA radar (as opposed to PESA on J-10B) and improved avionics compared to J-10B. I'm not sure that really deserves a new variant, but it seems like this particular aircraft has went through more flight testing than a usual production aircraft. So the second batch will definitely be different from the first batch. This second batch should be the first PLAAF aircraft to be equipped with AESA radar.

US Needs New Stealth Fighters To Combat China's J-31

China recently demonstrated its second fifth-generation stealth fighter, the J-31, for the 10th Zhuhai Airshow held in Guangdong from Nov. 11-16. Dave Majumdar, an American defense expert, thus suggests in Washington's National Interest that the US must put the F-35 into service or develop new fighters to face this challenge.

China has come to realize that fourth-generation fighters such as the J-10, J-11, Su-27 and Su-30 will be obsolete when facing American fifth-generation stealth fighters like the F-22 and F-35, an official from the Pentagon said. "The price of admission for a fifth-gen war is a fifth-gen airplane and they get that," the official was quoted as saying. Many US aviators believe that the J-31 was built based on stolen F-22 and F-35 technologies and will eventually be as powerful as the two American fighters.

"I think they'll eventually be on par with our fifth-gen jets because industrial espionage is alive and well," an F-35 test pilot told the US Naval Institute. A senior official from the US Air Force said that an F-22 has a 30-to-one kill ratio versus a Su-30 or J-11 outside of a surface-to-air missile environment. When the J-20 and J-31 enter service with the PLA, even a three-to-one kill ratio advantage becomes costly.

Facing this new challenge, the official suggested those who question the need for the F-35 to rethink their logic. "They may be complex, expensive and still immature, but they are a quantum leap over every other fighter in our arsenal," said he. Believing that China will eventually make the J-20 and J-31 into perfect stealth fighters, the official suggested the United States to learn from China's commitment to upgrading its military technology.

China's Carriers May Carry Modified J-20 Stealth Fighter

China is likely to complete the construction of its second and third aircraft carriers with the ability to carry J-20 fifth-generation stealth fighters, although a carrier-friendly model may need to be designed first, reports the PLA-run China National Defense News.
China's domestic aircraft carriers will look very similar to the Liaoning, the country's first aircraft carrier bought from Ukraine and refitted. They are most likely to be equipped with a ski-jump ramp, said Admiral Jonathan W Greenert, the US chief of naval operations. The displacement of each vessel will be somewhere between 65,000 and 70,000 tons.

The PLA Navy is planning to form two composite air hangar decks, with 50 fighters for each carrier. However, the design of the Chengdu J-20 is currently too large to be deployed aboard the Liaoning, according to the report. Domestic carrier versions will have to be larger to accommodate them, putting them at an estimated 80,000 tons. Furthermore, they may use a steam catapult or electromagnetic aircraft launch system.

The current J-20 prototype lacks the design specs necessary to take off from a carrier. The length of the first domestically built aircraft carrier may be be longer than the Liaoning by an estimated 20 meters but a new version of the J-20 will have to be designed in any case to be more like the more compact J-15. China's new carrier wing may come equipped with 25 J-15Bs and 25 J-20s.

US Says F-35 Secrets Showing Up in China’s Stealth Fighter

A cyber espionage operation by China seven years ago produced sensitive technology and aircraft secrets that were incorporated into the latest version of China’s new J-20 stealth fighter jet, according to U.S. officials and private defense analysts.

The Chinese cyber spying against the Lockheed Martin F-35 Lightning II took place in 2007 under what U.S. intelligence agencies codenamed Operation Byzantine Hades, a large-scale, multi-year cyber program that targeted governments and industry.

Defense officials said the stolen data was obtained by a Chinese military unit called a Technical Reconnaissance Bureau in the Chengdu province. The data was then passed to the state-run Aviation Industry Corp. of China (AVIC).

An AVIC subsidiary, the Chengdu Aircraft Industry Group, used the stolen data in building the J-20, said defense and intelligence officials familiar with reports of the illicit tech transfer.

Pentagon technology security officials in 2011 opposed a joint venture between General Electric and AVIC over concerns that U.S. fighter jet technology would be diverted to AVIC’s military aircraft programs. The Obama administration ignored the concerns and instead has since promoted the systematic loosening of technology controls on transfers to China.

The Office of Director of National Intelligence is known to have details of AVIC’s past involvement in illicit arms transfers and its role in obtaining sensitive F-35 technology through cyber espionage, the officials said.

The F-35 data theft was confirmed after recent photographs were published on Chinese websites showing a newer version of the J-20. The new version of the radar-evading aircraft had incorporated several design upgrades since the first demonstrator aircraft was revealed in 2011.

According to the officials, the J-20 has progressed from prototype to demonstrator. One of its most significant weapons enhancements is a new electro-optical targeting system under its nose.

Additionally, protruding engine nozzles seen in the earlier version have been hidden, an attempt to further reduce the jet’s radar signature. The newest J-20 also appeared with a different radar-absorbing coating.

Photos of the newer J-20 were first posted online on Chinese military forums on Jan. 17. The Pentagon’s Defense Science Board revealed earlier this year that system design information on the F-35 was obtained from cyber attacks.

The new Terminal High Altitude Area Defense missile systems and Patriot Advanced Capability-3 (PAC-3) missile defenses, along with many other systems, were compromised through cyber espionage, the board said in a report.

Most details of the Chinese cyber espionage campaign to obtain F-35 technology remain secret. However, the Chinese probably obtained the F-35 secrets from Lockheed Martin, its subcontractors, or U.S. allies involved in the development program. Allies that took part in the F-35 program include the United Kingdom, Israel, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and Turkey.

A Chinese Academy of Military Sciences official, Du Wenlong, told Chinese state television on Feb. 20 that the new J-20’s shortened exhaust nozzles, along with tail and vertical fin modifications, are designed to reduce radar detection.

Du also said that a “revolutionary” breakthrough allowed the twin engines to increase both power and reliability. China’s inability to manufacture quality jet engines has been a weakness of its aircraft manufacturing programs.

Du also said that the electro-optical targeting system provides better surveillance and strike capabilities against both land and sea targets.

The J-20 also has a larger weapons bay than the U.S. F-22, which allows it to carry more powerful missiles that can be used against “aircraft carrier and foreign AEGIS ships,” Du said.

U.S. officials said the new J-20 had undergone ground tests, but it had not been flight tested as of early March.

Richard Fisher, a specialist on Chinese weapon systems, said the new J-20 was flight tested on March 1 and demonstrated the enhanced fifth generation jet fighter features.

Fisher, with the International Assessment and Strategy Center, said it is “very curious” that the new J-20 featured its new electronic targeting system under its nose. That location increased its field of view and is similar to the targeting system on the F-35.
