How China’s Jets Threaten Russia


By Richard Weitz

The China International Aviation and Aerospace Exhibition, better known as ‘Airshow China,’ used to see Russian arms dealers descend on the event to peddle their wares to potential Chinese customers. Held every other year in the city of Zhuhai, the Russians were eager to persuade potential Chinese customers to part with their cash.

But last month, few Russian sellers showed up. Their absence is part of a broader trend in defence ties between the two nations, a trend that has seen a dip in the volume of Russian sales of military equipment and technologies to China.

Up until a few years ago, Beijing was buying large quantities of Moscow’s surplus Soviet-era military products, including expensive tanks, warships and warplanes. But over the last few years, the Chinese have declined to sign contracts for any major weapons systems from Russia, while the dwindling number of major weapons systems China now receives are items that Beijing purchased years ago.

All this leaves China buying mostly select subsystems or replacement items for larger platforms it has already acquired from Russia. For example, during a November 9 meeting in Beijing of the Russian-Chinese intergovernmental commission on military cooperation, the head of China's Central Military Commission, Guo Boxiong, and Russian Defence Minister Anatoly Serdyukov signed contracts to provide China with ‘spare parts for air defence systems, aviation and navy equipment.’

So why the change? Essentially, China no longer needs Soviet-era systems as the Chinese defence industry can now manufacture Soviet-era military technologies when it needs to (and in many cases can exceed this level). Beijing now wants to purchase more sophisticated armaments, often the latest-generation Russian systems.

The problem for China is that Moscow’s policymakers are reluctant to sell for fear that the Chinese will simply copy its technology and incorporate these advances into indigenous systems, some of which Chinese arms dealers can then offer to export to other countries in direct competition with Russian offerings.

China certainly appears to have form in this department. Russian and international sources agree that Chinese engineers and technicians copied one of Russia’s most famous and lucrative military export items, the Sukhoi-27 fighter jet. Looking to acquire advanced military technology from new sources following the imposition of the Western arms embargo in 1989, the Chinese government spent $1 billion in 1992 on acquiring two dozen turn-key Su-27s from a Russian military-industrial complex that had gone broke following the collapse of the Soviet military-industrial complex. After trying out the plane, the Chinese decided to buy 200 more, but they wanted to build them in China.

In return for a Chinese commitment to spend $2.5 billion to purchase 200 kits of imported Russian parts to assemble the plane under license, and a pledge not to re-export the planes without Moscow’s permission, Russia gave the Chinese defence industry the blueprints for the Su-27.

After building 100 planes, the Chinese cancelled the contract for the remaining 100 on the grounds that the Su-27 design no longer met the Chinese Air Force’s increasingly stringent performance requirements. However, in 2007, the J-11B began to appear in the Chinese media, a plane that looked eerily similar to the Su-27.

The Chinese claim that about 90 percent of the major subsystems fitted on the J-11B are manufactured in China, but like the Su-27, the J-11B is a single-person multi-function fighter designed to match the US F-16, one of the most widely available US-made fighter planes in recent decades. The J-11B is built by the Aviation Industry Corp. of China, which makes all the PLA’s combat aircraft, at the Shenyang Aircraft Corporation—the same place the Su-27K was assembled.

This experience has made the Russians wary about transferring further military aircraft technology to China. Indeed, fears of Chinese copying reportedly led the Russian government to reassess the wisdom of selling the highly advanced Su-33 fighter planes for possible use on future Chinese aircraft carriers. The negotiations for a possible sale were reportedly stopped when, according to the Russian press, the Chinese asked to buy only two of the Su-33 planes for a ‘trial.’

The Russian side sees the problems over the Su-27 as part of a broader problem, with some Russian analysts estimating that the export of illegally manufactured Russian arms costs the country as much as $6 billion annually, as well as damage to its reputation.

That said, these alarm bells haven’t put the Su-33 sales completely on ice, not least because the Chinese seem so eager to acquire the fighter to complement their expected rollout of their new aircraft carriers. This urgency has meant they’ve been offering various concessions such as agreeing to buy more planes and to accept more stringent intellectual property protection.

But it’s not just the Russian government that’s concerned. The Sukhoi Aviation Holding Company has been alarmed by reports that the Chinese may have reverse engineered a Su-33 prototype acquired in 2001 from Ukraine and that it’s now planning to produce it under the name of J-15.

These concerns come at a time when there are indications the Chinese might actually need to buy the more advanced Su-35 if the J-11B is unable to fulfill all its planned roles. This would mean that the Su-35 would fill the role of an air superiority fighter, while the J-11B would serve in less demanding missions, just as the high-end F-15 and low-end F-16 did for the US Air Force.

But despite the speculation over the Su-35, Russian arms dealers appear to have resigned themselves to selling a significantly lower volume of weapons to China rather than risk exporting its most sophisticated weapons. Anatoly Isaikin, general director of Rosoboronexport, predicts that Chinese purchases in the coming years will amount to only 10 percent of Russian arms exports. Besides the reduced appeal of selling China only a few systems before they are copied, Russian sellers worry that the Chinese will also seek to sell their new systems in third-party markets, potentially in competition with Russian offerings. (Essentially the Chinese could find a niche by selling weapons only somewhat less capable than their Russian equivalents, but for a much lower price).

The Russian dealers have good reason to be concerned. The Chinese are already beginning to adopt a high profile at international air shows, and last year demonstrated their new L-15 trainer jet at the 2009 Dubai Air Show. This year, they began offering advanced systems for sale at the Eurosatory arms fair in France and the Farnborough Air show in the United Kingdom. At the latter event, the Chinese for the first time showcased overseas their new JF-17 ‘Thunder’ multirole fighter jet, co-developed with Pakistan (and known in China as FC-1 Xiaolong).

The Russian government approved the use of a Russian engine in this jet, which is about as sophisticated as a MiG-21, because Russian defence firms don’t sell warplanes to Pakistan. But this plane could still become a major export item since the Chinese and Pakistanis can offer the JF-17 at a much lower price (of about $15 million) than the more sophisticated combat planes being sold by Russian, US and European aircraft companies. Azerbaijan, Myanmar, Egypt and other traditional Russian arms customers, for example, have expressed an interest in the JF-17.

The Chinese have already sold around 250 Hongdu K-8 trainer and ground-attack jets, which were also co-developed with Pakistan, to developing countries such as Egypt, Ghana, Sudan and Venezuela. And in the latter case, China's first major sale in South America, the K-8 defeated a Russian competitor. In addition, China has sold about 100 F-7 jet fighters, based on the Russian MiG-21, to Bangladesh, Namibia, Nigeria and other developing countries. All this means that Russian dealers could now either lose more military aircraft sales to developing countries, or be forced to offer lower prices and better terms to keep their clients.

These developments will also likely be being watched uncomfortably by US diplomats. It’s true that Chinese exporters are unlikely to cut into US military sales anytime soon. But while in the past US representatives only needed to negotiate mutual sales restraints with Russia, they will now need to induce the Chinese to curb their natural inclination to sell weapons to Iran, North Korea and other regimes frozen out of traditional arms markets. The experience with Pakistan, which has received sophisticated nuclear and missile technologies from Chinese suppliers despite years of US lobbying and sanctions, isn’t encouraging.

Meanwhile, the Chinese are by some estimates not all that far behind the Russians in deploying fifth-generation stealth fighter jets. The Russians have only begun testing their prototype, while the Defense Intelligence Agency estimates that the PLA Air Force will deploy stealth fighters in ‘meaningful numbers’ in about a decade.

Although Russian defence planners remain confident that they won’t face a Chinese military threat for at least a decade, the US, Japanese and other Pacific Navies will have to consider much sooner how to match these growing capabilities. Indications of how they intend to might be clearer in the new Japanese annual white paper on national defence, which should be issued this month.

But there’s one more twist for Russia. While Soviet defence enterprise directors would have been incredulous at the idea, the Russian government may one day consider purchasing major weapons systems from China. The Russian government, disturbed by endemic problems in the Russian shipyards, has already been seeking to buy large amphibious ships from France and for now, the Russian Defence Ministry has confirmed that it will no longer purchase aircraft carriers from indigenous sources. (Russian defence companies have never recovered from the disintegration of the Soviet integrated military-industrial complex, when aircraft carriers were built in Ukraine).

But the irony is that if the Russians ever decide they need carriers again, a logical source would be China, as its years of extensive industrial copying likely mean that Chinese weapons systems will present fewer interoperability problems than systems from Western suppliers. So, in the end, Russian sailors and pilots could well end up feeling most at home when their hardware is made in China.

Sukhoi T-50/I-21/Article 701 PAK-FA Sukhoi T-10/Su-27/30/33/35/35S/37 Flanker



First prototype of the PAK-FA during an early test flight, January 2010. Intended to replace the Flanker series, the PAK-FA improves upon the superlative aerodynamic and kinematic performance of the Flanker, but adds competitive Very Low Observable capability, until recently unique to United States designs (Sukhoi image).

The emergence of the Russian Sukhoi T-50 / PAK-FA (Перспективный Авиационный Комплекс Фронтовой Авиации), the intended replacement for the T-10 Flanker series, marks the end of the United States' quarter century long monopoly on the design of Very Low Observable (VLO) or stealth aircraft. Designed to compete against the F-22 in traditional Beyond Visual Range (BVR) and Within Visual Range (WVR) air combat, the PAK-FA shares all of the key fifth generation attributes until now unique to the F-22 - stealth, supersonic cruise, thrust vectoring, highly integrated avionics and a powerful suite of active and passive sensors. While the PAK-FA firmly qualifies as a fifth generation design, it has two further attributes absent in the extant F-22 design. The first is extreme agility, resulting from advanced aerodynamic design, exceptional thrust/weight ratio performance and three dimensional thrust vectoring integrated with an advanced digital flight control system. The second attribute is exceptional combat persistence, the result of a 25,000 lb internal fuel load. The internal and external weapon payload are likely to be somewhat larger, though comparable to those of the F-22A.



The new Su-35S is labelled a “4++ Generation” derivative of the baseline Su-27S Flanker B. It is a comprehensive redesign of the aircraft's systems, and employs a supercruise capable 117S variant engine. Depicted the second prototype during flight test. The Su-35S is expected to be the last Flanker variant to be mass produced before the PAK-FA enters full rate production (KnAAPO image).

Sukhoi's T-10 Flanker family of combat aircraft is without doubt the outstanding design in the final generation of Soviet Cold War era systems. Since the fall of the USSR, the Flanker has continued to evolve and is now by far the leading Russian military technology export. The Flanker has been exported globally, and the Asia-Pacific now boasts the world's largest inventory of these versatile and highly capable combat aircraft. China, India, Vietnam, Indonesia, Malaysia now operate or have ordered variants of the Flanker.

Reacting to the proliferation of the Flanker, Japan is seeking to acquire the F-22A Raptor. South Korean public debate shows an increasing interest in acquiring the F-22A, for the same reasons Japan seeks it. Australia is however pursuing the opposite path in its planning for the future region, acquiring 'interim' F/A-18F Super Hornets, and seeking the Joint Strike Fighter long term, neither of which are competitive against advanced Flanker variants.

Kematian Misteri Burung Jatuh Dari Langit

Teori serangan UFO




PADA malam itu, beberapa detik sebelum menjelang tahun baru 2011, beribu-ribu ekor burung blackbird jatuh bak hujan hitam di pekan kecil Beebe yang terletak di negeri Arkansas, Amerika Syarikat (AS).

Dianggarkan lebih 5,000 burung hitam bersayap merah jatuh dari langit dan bertaburan di atas jalan, bumbung dan halaman rumah di kawasan seluas 731 meter persegi. Di sesetengah kawasan, tanah bertukar menjadi gelap.

Penduduk setempat yang keluar untuk menikmati pancaran bunga api dan meraikan kedatangan tahun 2011, panik dengan apa yang berlaku dan bergegas memasuki kediaman masing-masing apabila haiwan bertubuh kecil itu mula jatuh di sekeliling mereka.

Ada bangkai yang jatuh mengenai seorang wanita yang sedang berjalan bersama anjingnya manakala seorang lagi terpaksa menggunakan payung untuk melindungi diri.

Seorang penduduk tempatan, Shane Roberts berkata, ia berbunyi seperti hujan batu yang sangat dahsyat di atas bumbung rumahnya.

"Apabila saya keluar, alangkah terkejutnya apabila melihat ketulan-ketulan hitam bertaburan. Apabila saya pergi lebih dekat, ia adalah bangkai burung," katanya yang menyifatkan kematian tersebut sebagai sesuatu yang aneh.

Sementara itu, Penyelia Jabatan Jalan bandar berkenaan, Milton McCullar berkata, ia seperti adegan dalam filem Alfred Hitchcock di mana semua lampu di papan suis kecemasan menyala dan semua orang berada dalam situasi yang mencemaskan.

Kiamat

"Ada penduduk yang panik dan beranggapan dunia hampir kiamat," ujar Ketua Polis tempatan, Ellie Cullum seperti dipetik Mail Online.

Kehadiran ribuan bangkai burung di kawasan kejiranan tersebut diterima sebagai misteri alam.


MISTERI kematian hampir 5,000 burung hitam sayap merah belum dapat dirungkai.


Namun, yang menjengkelkan penduduk setempat ialah apabila pekerja pembersih alam sekitar datang memakai sut kalis api, topi keledar dan topeng gas hanya untuk membuang bangkai burung.

Belum pun reda kes burung jatuh dari langit diperkatakan, pakar pengkaji haiwan di Arkansas bertambah bingung apabila lebih 100,000 bangkai ikan drum ditemui di sepanjang 32 kilometer di tebing dan permukaan Sungai Arkansas, berhampiran Ozark yang terletak kira-kira 200 kilometer dari bandar Beebe.

Anehnya, hanya spesies ikan drum yang didapati mati sedangkan ikan spesies lain masih hidup.

Adakah kejadian aneh ini mempunyai kaitan antara satu sama lain?

Terdapat beberapa teori yang diketengahkan oleh pihak tertentu mengaitkan punca kepada misteri kematian haiwan tersebut.

Antaranya, burung terlanggar objek terbang yang tidak dikenali (UFO), hujan batu, tekanan akibat bunyi kuat bunga api dan proses teras bumi menyahmagnet.

Malah, ada juga pendapat mengatakan kejadian tersebut adalah petanda akan berlakunya kiamat pada 2012 seperti yang diramalkan oleh tamadun kuno Maya di Mexico.

Walaupun ini bukan kali pertama AS berdepan dengan kematian spesies haiwan secara misteri, namun kali ini negara Uncle Sam itu gusar dengan apa yang terjadi.

Seorang pakar dari Jabatan Perikanan dan Akuakultur Universiti Arkansas, Dr. Andrew Goodwin berkata, perubahan drastik antara cuaca sejuk dan panas boleh membuatkan ikan terkejut dan membunuh mereka.

"Faktor yang memberi impak kepada ikan itu ialah perubahan suhu yang ketara," katanya.


DI Arkansas, ikan yang mati adalah daripada spesies drumfish sahaja. Peliknya ikan spesies lain yang ada di sungai sama tidak terjejas.


Dalam laman-laman blog, perdebatan mengenai punca kematian haiwan tersebut juga semakin kerap diperbincangkan.

Kali ini ramai yang mengaitkan kematian haiwan-haiwan Arkansas itu ada kaitan dengan konspirasichemical trail atau jejak kimia yang sering terjadi di negeri itu.

Menurut seorang pengikut teori konspirasi, Jeff Rense, jejak kimia dapat dilihat seperti jejak asap di udara. Ia kemudian akan melebar dan tetap kelihatan untuk tempoh beberapa jam.

Menurut beberapa pihak yang berfikiran sama dengan Jeff, mereka berpendapat jejak itu adalah bahan kimia yang sengaja disembur oleh kerajaan AS sebagai 'kawalan populasi'.

Ada juga berpendapat bahawa jejak itu adalah eksperimen pengendalian cuaca.

Bagaimanapun, teori itu meragukan kerana belum ada penemuan menyatakan semburan bahan konduktif elektrik yang menjadi sebahagian daripada program senjata super elektromagnetik boleh mengendalikan cuaca terutama pemanasan global.

Dalam sebuah buku terbitan badan pengkaji sains dan angkasa AS, mereka menafikan adanya jejak kimia tersebut sebaliknya menyatakan ia adalah wap air dan kristal ais yang membentuk jejak-jejak asap di udara.

Tidak kurang juga yang mengaitkan bunyi kuat daripada dentuman bunga api menyebabkan burung tertekan serta hilang kawalan navigasi sehingga mengakibatkannya melanggar bangunan dan pokok.

Namun, ahli akademik dan pengasas yayasan untuk Institut Kajian Gelagat Burung, Dan Cristol, menolak dakwaan tersebut.


BANGKAI burung hitam yang menghujani kawasan kejiranan Louisiana mendatangkan panik kepada penduduk setempat.


"Pesta sambutan tahun baru dengan dentuman bunga api berlangsung setiap tahun dan mengapa kejadian sama tidak berlaku sebelum ini?

"Sukar untuk meletakkan punca ke atas bunga api melainkan seseorang telah meniup sesuatu ke dalam sarang burung sehingga menyebabkan haiwan tersebut terpelanting ke udara," jelas Dan.

Di sebalik pendirian sebahagian pakar yang mengaitkan cuaca tidak stabil sebagai punca, profesor Fizik dari New York, Michio Kaku berkata, kematian misteri tersebut kemungkinan besar terjadi akibat hentaman angin laju yang ganas yang menghentam kawanan burung berkenaan.

Walau apa pun teori yang dibahaskan, sehingga kini belum ada lagi pihak yang tampil dengan hasil ujian yang boleh membuktikan punca kematian dua spesies haiwan tersebut.

Kematian haiwan yang direkodkan di Arkansas bukan yang terburuk dalam fenomena misteri ini.

Malah, rentetan daripada apa yang berlaku di Arkansas, jumlah bangkai haiwan ditemui di beberapa kawasan di AS seperti Maryland, Texas, Kentucky, Louisiana serta Florida sangat mengejutkan.

Chengdu J-XX [J-20] Stealth Fighter Prototype

Chengdu J-XX [J-20] Stealth Fighter Prototype
A Preliminary Assessment

Elevated head on view of Chengdu prototype, December, 2010 (Chinese Internet).



Introduction



In late December, 2010, imagery of what is claimed to be China's new stealth fighter has emerged on a range of Chinese Internet sites.

There have been no official Chinese disclosures as yet, so many of the claims about the aircraft appearing in the media may only be speculation presented as fact.

The aircraft may be a technology demonstrator or a prototype for a mass production fighter aircraft. The latter is however much more likely, given that the Deputy Chief of Air Staff PLA-AF Gen. He Weirong claimed an IOC between 2017 and 2019, in a November, 2009, public disclosurei.

The following is a preliminary assessment only and subject to revision. APA will produce a more complete assessment at a future date, once more technical material and the detailed analysis of same becomes available.


Technical Observations on the Prototype Design


  1. The J-XX/J-20 is a large fighter, similar in size to an F-111. This first-of-type aircraft presents with a large dihedral canard-delta wing configuration; with a pair of outward/rearward canted all moving combined vertical/horizontal tails; and, similarly large, outward canted ventral fins/strakes which, if all moving like the tails and retained on any production version, will make for some quite advanced capability options in the areas of controllability and manoeuvrability. There is little doubt this configuration is intended to provide good sustained supersonic cruise performance with a suitable engine type, and good manoeuvre performance in transonic and supersonic regimes.
  1. The stealth shaping is without doubt considerably better than that seen in the Russian T-50 PAK-FA prototypes and, even more so, than that seen in the intended production configuration of the F-35 Joint Strike Fighter.
  1. The J-XX/J-20 design appears to be largely built around the stealth shaping design rules employed in the F-22A Raptor:
  1. The chined J-XX/J-20 nose section and canopy are close in appearance to the F-22, yielding similar signature performance in a mature design.
  1. The J-XX/J-20 trapezoidal edge aligned engine inlets are closest to the F-22, though appear to be larger and employ an F-35 style DSI (Diverterless Supersonic Inlet) design, obviously intended to improve on F-22 inlet edge signature.
  1. The J-XX/J-20 wing fuselage join, critical for beam and all aspect stealth, is in shaping and angle very similar to the F-22, and clearly superior to both the Russian T-50 PAK-FA prototypes and the F-35 Joint Strike Fighter.
  1. The J-XX/J-20 flat lower fuselage is optimal for all aspect wideband stealth, and emulates the F-22 design closely.
  1. Planform alignment of the J-XX/J-20 is impossible to fully assess until in-flight imagery becomes available.
  1. The J-XX/J-20 nose and main undercarriage doors employ X-band optimised edge serration technology, based on F-117A and F-22 design rules.
  1. The aft fuselage, tailbooms, fins/strakes and axi-symmetric nozzles are not compatible with high stealth performance, but may only be stop-gap measures to expedite flight testing of a prototype.
  1. The airframe configuration and aft fuselage shape would be compatible with an F-22A style 2D TVC nozzle design, or a non-TVC rectangular nozzle designed for controlled infrared emission patterns and radio-frequency stealth.
  1. The airframe configuration is compatible with ventral and side opening internal weapon bays, and large enough to match or exceed, by some degree, the internal weapons payload of the F-22A Raptor.
  1. Internal fuel fraction is also likely to be high, given the fuselage configuration and large internal volume of the big delta wing. This indicates an intent to provide a sustained supersonic cruise capability, in the manner of the proposed FB-22.
  1. The PLA have not disclosed the engine type. There are claims that the Russians supplied supercruise capable 117S series engines, though, subject to the overall efficiency of the aircraft’s aerodynamics, these would likely not be sufficient to extract the full performance potential of this advanced airframe.
  1. The intended sensor suite remains unknown. China has yet to demonstrate an AESA radar, or an advanced indigenous Emitter Locating System (ELS). However, these could become available by the time this airframe enters production. Suitable Russian hardware is currently in late development and/or test.


The J-XX/J-20 is a large fighter, similar in size to an F-111 (Chinese Internet).


(US DoD)


Above, below: Histograms of distances between PLA-AF and PLA-N fixed basing along the eastern seaboard of mainland China and US airfields at Kadena AFB on Okinawa and Andersen AFB on Guam. The J-XX/J-20 is well sized to hold both of these bases at risk (Kopp, 2005).




General Conclusions



The size of the J-XX/J-20 airframe, and the self evident focus on supersonic persistence, suggests, at a minimum, an intention to provide a long range interceptor for anti-access operations in the Second Island Chain geography. It is likely any production design J-XX/J-20 will incorporate an aerial refuelling probe to further extend its large operating radius.

A stealthy, supercruising, long range interceptor would provide the PLA-AF with the capability to penetrate an opposing IADS to destroy assets like E-3 AWACS, RC-135V/W Rivet Joint, other ISR systems, and importantly, Air Force and Navy tankers. This would significantly complicate if not close down air operations from Andersen AFB and fixed basing in the Ryukyu chain, Japanese main islands, and Korean peninsula, during the opening phase of any contingency.

Naval task forces structured around CVBGs and operating within the 1,000 NMI plus radius of the J-XX/J-20 would be at significant risk of rapidly losing their E-2C/D AEW&C and EA-18G Growler Electronic Attack coverage during the opening phase of any contingency.

Any notion that an F-35 Joint Strike Fighter or F/A-18E/F Super Hornet will be capable of competing against this Chengdu design in air combat, let alone penetrate airspace defended by this fighter, would be simply absurd. The F-35 Joint Strike Fighter and F/A-18E/F Super Hornet are both aerodynamically and kinematically quite inferior to the as presented J-XX/J-20 design, and even the shape based VLO capability in the J-XX/J-20, as presented, will effectively neutralise any sensor advantage either type might possess against earlier Russian and Chinese fighter designs.


Multi-Role Options and Production Numbers



The J-XX/J-20 design could be employed as a penetrating strike aircraft, in the combat radius class of the F-111 or Su-34 Fullback, if equipped with internal guided bombs, such as the Luoyang/CASC LT-3 Laser / Satellite Aided Inertially Guided Bomb, the FT-1, FT-2, FT-3, FT-4, FT-5 and LS-6 series Satellite Aided Inertially Guided Bombs. These are Chinese analogues to the US JDAM, some including glide wing kits modelled on the JDAM-ER. CASC displayed compact 250 lb and 125 lb variants of the LS-6 at Zhuhai in 2010, these derivative weapons being direct analogues to the US GBU-39/B Small Diameter Bomb, currently being integrated on the F-22A Raptorii.

A mature J-XX/J-20, with a full strike capability, would be a direct one-for-one equivalent to the proposed dual role FB-22A, which was championed by Dr. James G. Roche during his tenure as SecAF, until 2005iii.

The PLA-AF has not disclosed as yet intended production quantities. The stated IOC of the J-XX/J-20 directly aligns with the retirement date of the second tranche of Su-27SK Flanker B and first tranche of Su-30MKK Flanker G currently in operational service. It is a reasonable conclusion that the J-XX/J-20 is intended as an eventual replacement for PLA-AF Flanker B/G and later PLA-N shore based Su-30MK2 Flanker G long range multirole fighters. If the J-XX/J-20 is intended to directly replace PLA Flankers, numbers in the order of 400 – 500 aircraft are credible.
