Can you tell me which Chinese fighter has seen more extensive combat than American planes. Forget about your air-force, even your army hasnt fought a war in almost 40 years. Besides your "hot-air" cage-rattling warning to Taiwan every year....your entire military officer corp, up and down the ranks - has got zilch for real combat experience.

There is no military in the world that has as much combat(air and ground) and COIN experience as the US military in the last 3 decades. Thats a fact. Whether you agree with Iraq, Bosnia, AFPak, Kuwait, wars or not - The US military is probably the most battle hardened military in the world today.

After the US, I would put Israel and India. Hell, even the Sri-Lankan army has more battle experience than the PLA.

As for China stop lending money to the US, people will just buy less Chinese products. Actually that is already happening, people in the US are starting to save more and reduce the credit-card debt. Its going to affect China's exports to the US, regardless of whether China keeps lending.
I could not agree more with you. In previous 40 some years, the Chinese have not fought any war while the American and her allies have not been stopping fighting in other people's territories. But the Americans are keeping complaining about the threat from China all the time.

J20 is only the second fighter (JF-17 not counted) the Chinese is trying to produce instead of cloning. So there must be a lot of problem and could not be compared with the USA. In fact, due to deficiency of Jet engine performance, J20 has to be designed in this form of aerodynamics with canard to enhance agility. Nevertheless, the Chinese is willing to take this risk and develop her own fighter rather than go along with the Russian. They believe there won't be any major war with India, nor Japan, nor USA in the near future. The American knows it too but its defense agent needs an enemy to justify for more finance.

Sorry, it sounded like "mattster" was trying to put India in the same league as the US, or even at the same league as Israel.

The US military is probably the most battle hardened military in the world today.

What do you think of the above statement, AV?

Also, I would agree that this "superpower" nonsense is complete BS. Hence the sarcasm.

China is going through the normal transition from have not to have. It would take another 50 or more years before China could possibly getting close to the West in military technologies. The Chinese leaders have more than once confirmed this. Lets talk about the J20 here rather than "who is the super power".

if US dont get involved,taking Taiwan back is a easy thing.i admit US still the super power.

however,i would like china to be a super culture rather than a super power,which seems to need a long time.

AS we all know,ancient china is famous for its culture,not for the military

America could have easily invaded Cuba after collapse of the Soviet union.They did not do that.They do not even threaten of using military force.There is no comparison with China that puts up a show of its military strength in the Taiwan straits and trying to conquer that island.

it seems that you know exactly that USA could not invade Cuba ,as long as Soviet didn't collapse.....so do Taiwan and USA.

Taiwan still stands there,just because of the support from USA....Without the support of USA, PRC could crack down Taiwan just as easily as one elephant cracks down one ant.

An Initial Assessment of China's J-20 Stealth Fighter

Publication: China Brief Volume: 11 Issue: 8May 6, 2011 05:31 PM Age: 5 days
By: Carlo Kopp

J-20 Radius
The maiden test flight in January 2011 of China's J-20 stealth fighter prototype is an important strategic milestone in several different respects, and is part of an ongoing effort by China to develop advanced military technology [1]. The J-20 is the first combat aircraft developed by China that qualifies as "state of the art" by Western measures. It also shows that China has mastered "stealth shaping" technology—the essential prerequisite for developing stealth aircraft. Finally it shows that China has managed to integrate its strategic planning with the functional definition of a modern combat aircraft. Once fully developed, the J-20 has the potential to alter the regional balance in the Asian air power strategic game, by rendering nearly all regional air defense systems ineffective.

The People's Liberation Army (PLA) has yet to disclose any of the intended performance parameters of this fighter aircraft, or its intended avionic systems and weapons fit. As a result, analysts are left with one choice only, which is to apply analytical criteria such as size, shape and configuration to draw an estimate of the aircraft's characteristics. If applied with rigor, this technique can produce highly accurate results [2].

Scaling the dimensions of the J-20 against proximate ground vehicles of known types in photographs does yield very accurate dimensions, showing that the J-20 is a large fighter, in the size class of the United States F/FB-111 family of aircraft, or the proposed but never built FB-22A "theater bomber." This in turn indicates an empty weight in the 40,000 – 50,000 lb class, depending on construction technique used in the design, and an internal fuel load of up to 35,000 lb. Inevitably, this yields subsonic combat radius figures in the 1,000 – 1,500 nautical mile class, subject to the thrust specific fuel consumption of the production engine in subsonic cruise. The J-20 is therefore a fighter built for reach, and would be competitive in range performance against the F/FB-111 series, the F-15E Strike Eagle series, and the new Russian Su-35S Flanker series. The implications of this will be discussed further.

J-20 Capability Assessment

The shaping of the J-20 prototype has important implications from the perspectives of aerodynamic performance and stealth.

The delta canard configuration of the J-20 design is common to the earlier Chengdu J-10, the European Eurofighter Typhoon, the French Rafale and the prototype of the Russian MiG I.42 super cruise fighter. This configuration provides for high supersonic performance, excellent supersonic and transonic turn performance, and better short field landing performance than conventional delta wing designs. If equipped with suitable engines, a J-20 would be very efficient in supersonic cruise regime, with excellent close combat maneuver performance. The intended engine fit has not been disclosed, although there has been speculation that the prototype may be fitted with imported Russian Al-41F1S or Item 117S engines common to the Su-35S and T-50 PAK-FA prototypes. The Al-41F1 is an evolution of the supersonic cruise engine developed for the MiG I.42, with a more powerful Item 129 engine in development for the production T-50 [3].

There has been some media speculation about an indigenous engine for the J-20, designated the WS-15, but no substantial official disclosures to date [4].

The detail airframe stealth shaping design of the J-20 is clearly based on shaping design rules developed by the United States, and employed primarily in the F-22A Raptor, but with an engine inlet design closer to the F-35 Joint Strike Fighter. This is important insofar as most radar signature improvement in stealth designs is a result of shaping, with radar absorbent materials and detail design employed primarily to "clean up" unwanted reflections that could not be suppressed by shaping. Qualitative and quantitative analysis performed by the author indicates that the J-20 has the potential to yield much better stealth performance from the front and sides than the F-35 Joint Strike Fighter, and possibly as good as the F-22A Raptor, should Chinese designers master materials and detail design techniques adequately. The design has only two apparent weaknesses, which are the curvature in the slab side shaping, which provides broader reflection lobes than necessary, and the circular exhaust nozzle, a weakness common to the F-35 and T-50. Both may be artifacts of the prototype and may not be features of a future production aircraft.

The shaping design will be highly effective against radars operating above the 1 GigaHertz L-band, but much less effective below this band. This band coverage encompasses most surface based and airborne search, acquisition and fire control radars used by the United States and its allies in Asia.

A survey of twenty-six unclassified English language Chinese research papers on radar absorbent materials indicates a high level of research effort in the area, but mostly for materials not suitable for aircraft applications. Research in this area is usually not published in the West and there is no reason to believe China would do differently [5].

The available data supports the proposition that the J-20, once fully developed, will be a high performance stealth aircraft, arguably capable of competing in most cardinal performance parameters (i.e. speed, altitude, stealth, agility) with the United States F-22A Raptor, and superior in most if not all cardinal performance parameters against the F-35 Joint Strike Fighter.

The intended role of the J-20 has not been disclosed officially, and widely varying views have been expressed by various observers.

The suitability of this design for various roles will depend primarily upon what engines are installed, and whether faceted stealthy exhaust nozzles modeled on the F-22 design are employed, the latter being important for deep penetration through air defense systems.

If the engines deliver 40,000 – 50,000 lb class thrust performance, the J-20 will be viable as an air combat fighter, air defense interceptor and deep strike fighter. If thrust performance falls below this benchmark, the aircraft would lack the agility for close air combat, but still be very effective as an interceptor or bomber.

What this suggests is that if Chinese engine technology has not matured enough by the latter half of this decade, when IOC is planned for the J-20 [6], early variants could be employed as strike aircraft, or interceptors, with later variants "growing" into the air combat role as more powerful engines become available.

China has deployed or developed a range of new guided weapons suitable for internal carriage by the J-20. While no imagery as yet exists showing the configuration of the J-20 internal bays, the aircraft layout could permit a similar arrangement to the F-22A, but with a longer and deeper fuselage bay capable of carrying larger bombs, or even more weapons.

Richard Fisher at the International Assessment and Strategy Center has detailed a number of Chinese 5th Generation Air-Air Missiles, including evolved variants of the PL-12, modeled on the United States AIM-120 AMRAAM, the ramjet powered "PL-13" modeled on the European MBDA Meteor, and the agile thrust vectoring PL-ASR/PL-10, modeled on the A-Darter and Iris-T missiles [7].

Guided bombs suitable for strike against surface targets are also abundant. At the Zhuhai and CIDEX 2010 arms expos, Luoyang/CASC (China Aerospace Science and Technology Corporation) displayed a range of new guided bomb designs. These include the "Lerting" (Thunderbolt) LT-3, which is modeled on the US GBU-55/56(V)/B Laser JDAMs, the FT-1, FT-3 and FT-5 modeled on the U.S. GBU-32/35/38 JDAM satellite aided bombs, and the winged FT-2, FT-4, FT-6 and LS-6 planar wing glide bomb variants, broadly modeled on the Australian JDAM-ER glide bomb family. The LS-6 family also includes 50 kg and 100 kg small bombs, modeled on the U.S. Small Diameter Bomb series, but with cruciform strakes rather than planar wings [8].

The heavy emphasis placed by Luoyang/CASC on glide bombs is important, as these can be released by stealth aircraft from ranges well outside the detection range of the aircraft itself, which can thus remain unseen through the whole delivery maneuver, effecting complete surprise.

The strategic impact of a mature production J-20, even if limited to strike roles alone, would be profound. With sufficiently good stealth performance to defeat air defense radars in the L-band through Ku-band, the aircraft could easily penetrate all air defense systems currently deployed in Asia. Even should the aircraft be tracked by a counter-stealth radar, the high altitude supersonic cruise penetration flight profile makes it extremely difficult to engage by fighter aircraft and Surface to Air Missiles. The only fighters deployed in the Pacific Rim with the raw performance to reliably intercept a supersonic J-20 are the F-22A Raptor and Russian MiG-31 Foxhound.

The size of the J-20 and resulting fuel fraction indicate that the aircraft will be able to cover the "First Island Chain" without aerial tanker support, and with tanker support, reach targets across the "Second Island Chain" on subsonic cruise profiles. Nearer targets would be accessible on supersonic cruise profiles [9].

The Impact of the J-20

There can be no doubt at this time that a mature production J-20 with fully developed stealth and supersonic cruise capability would qualify as a "game changer" in the Asia-Pacific region.

The J-20's combination of stealth and supersonic cruise—the cardinal design feature of the F-22A Raptor—provides the capability to defeat nearly all extant Integrated Air Defense Systems. Defeat is effected by denying detection, and should detection occur, by kinetically defeating launched missiles, which cannot close with the target before it exits radar tracking range. Even without stealth, high altitude supersonic aircraft are challenging targets for all but the largest and longest ranging Surface to Air Missiles. Interceptor aircraft without a capability for sustained supersonic flight are typically ineffective against high altitude supersonic targets.

The development of the J-20 around the combination of stealth and supersonic cruise results in a design, which will be undetectable at range by almost all air defense radars operated by the United States and its numerous allies in the Asia-Pacific region. In practical terms, this results in the "block obsolescence" of most Asian air defense systems.

Another important consideration is that the J-20 is a large fighter and therefore, if flown on fuel efficient subsonic cruise profiles, will be able to reach targets at ranges of around 1,000 nautical miles without aerial refueling tanker support.

If flown from PLA airbases along the eastern seaboard of mainland China, the J-20 will thus be able to comfortably reach any target within China's "First Island Chain," unrefueled. These targets include airfields in Japan, South Korea, and former US Air Force airbases in the Philippines.

With modest aerial refueling support, the J-20 will be able to reach most targets situated along China's "Second Island Chain," including the strategically critical Guam facilities.

The strategic choices available to the United States and its allies for dealing with the J-20 are very limited; such is the potency of all aircraft combining stealth and supersonic cruise capabilities. These distill down to the deployment of large numbers of F-22A Raptor fighters in the region, and the development and deployment of "counter-stealth" radars operating in the HF, VHF, and UHF radio-frequency bands. Funding for the production of the F-22A was stopped in 2009, following an intensive political effort by Secretary of Defense Robert M. Gates. There is no program to fund the development and volume production of "counter-stealth" radars.

The incumbent U.S. Administration has thus committed itself politically to a path in developing air power for the U.S. armed services and allied air forces, predicated wholly on future opponents operating obsolete Soviet era air defense weapons and fighters. The unveiling of the Russian T-50 PAK-FA and Chinese J-20 over the last two years has not produced any significant changes in U.S. planning, which may challenge the United States and its Pacific Rim allies' strategic advantage in conventional air power.

True. There is a reason.

CAC designers are always haunted by weak indigenous engine. Assumption of WS-15 not being delivered in time is always in their equation. To make J20 perform decently from subsonic to supersonic with relatively weak engine, they have no choice but optimize its aerodynamic shape, and sometime even sacrifice a bit of stealth, as indicated in the quote above.

In this regard, American designers are much more comfortable. With a powerful and mature engine in hand, they have much wider choice. They can use engine's brutal force to achieve performance without compromise, while Chinese designers must rely on aerodynamic optimization to squeeze performance.

J-20 'Mighty Dragon' Optimised For Air Dominance

Within 24 hours of India and Russia inking a preliminary design contract (PDC) for the joint development of the twin-engined, tandem-seat 17.2-tonne Fifth Generation Fighter Aircraft (now called Perspective Multi-role Fighter), China's Chengdu Aircraft Industries Corp (CAC) on December 22 last year rolled out the first (No2001) of two flying prototypes of its fifth-generation single-seat J-20 'Mighty Dragon' 23-tonne air dominance multi-role combat aircraft. Subsequently, high-speed taxi trials of this prototype got underway, and its maiden flight, lasting 20 minutes, took place on January 11 at 12.50pm. Under development since 1998, the JXX, to be known as the Jian J-20 once it enters service by 2017, has been jointly designed by the CAC's Chengdu Aircraft Design Institute No611 and Shenyang Aircraft Corp's 601 Institute. The Shenyang Aero-Engine Research Institute, or Institute 606, was tasked in 1998 with developing the JXX's 18,350kg-thrust (180kN) Woshan WS-15/Qinling-2 turbofan and its thrust-vectoring nozzles. J-20 No2001, though, is powered by twin WS-10G Taihang turbofans (each rated at 135kN and equipped with FADEC controls), since the WS-15 will not be available until 2012. The WS-10G has been developed by Guizhou-based Honglin Group (AVIC's Factory No143). The J-20 is next scheduled to go from Chengdu to the China Flight Test Establishment (CFTE) at Yanliang, which is located northeast of Xian in central China's Shaanxi province. There, the two J-20 prototypes will undergo several phases of flight-tests and systems integration refinements, a process which will last until 2014. Following this, the first batch of up to eight CAC-built limited series production J-20s will be deployed first to the PLAAF's Dingxin air base, located in north-central China near the Shuangchengzi missile test range, for weapons qualification trials, and then to the PLAAF-owned Flight Test & Training Centre (FTTC) at Cangzhou air base south of Beijing, where service induction procedures will be tried, applied and finalised. Following this, the PLAAF is expected, by late 2017, to form a J-20 operational conversion unit at Jiugucheng air base with up to 16 J-20s.

The existence of the J-20 was first announced in a November 2009 interview on Chinese CCTV by Lt Gen He Weirong, deputy commander of the People's Liberation Army Air Force (PLAAF). He had then said that a 'fourth-generation' combat aircraft would be flown in late 2010 and become operational between 2017 and 2019. Work on fabricating the first of two J-20 flying prototypes got underway in late 2007 at CAC's No132 Aircraft Plant and a year later a full-scale mock-up was available for airframe fatigue-testing purpose. The J-20 has been designed to have a 0.05 square-metre radar cross-section (head-on), and its airframe features 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, will make for some quite advanced capability options in the areas of controllability and manoeuvrability. The flat body sides are aligned with the canted tails, the wing-body junction is clean, and there is a sharp chine line around the forward fuselage. The stealth shaping is without doubt considerably better than that seen in the two Sukhoi OKB-designed T-50 PAK-FA multi-role combat aircraft (MRCA) prototypes, and even more so, than that seen in the Lockheed Martin F-35 Joint Strike Fighter (JSF). The design appears to be largely built around the stealth shaping design rules employed in the Lockheed Martin F/A-22A Raptor. Takeoff weight is estimated to be 80,000lb without any weapons payload. The fuselage length is 21.5 metres, wingspan is 13.8 metres, height is 5 metres, and the weapon's bay's length is 6.52 metres. The chined nose section and frameless canopy bear a close resemblance to those of the F/A-22A, as do the trapezoidal edge aligned engine inlets, though they appear to be larger and employ a diverterless supersonic inlet design, obviously intended to reduce inlet edge signature. The J-20's wing-fuselage join, critical for beam and all-aspect stealth, is both in shaping and angle very similar to that of the F/A-22A, and clearly superior to those on the T-50 PAK-FA and F-35 JSF. The flat lower fuselage and planform alignment is optimal for all aspect wideband stealth, and closely emulates the F/A-22A's design. The nose and main undercarriage doors employ X-band optimised edge-serration technology similar to that on board the F-117A Nighthawk and F/A-22A. The main landing gears retract into body-side bays, indicating the likely presence side weapon bays ahead of them. The ground clearance is appreciably higher, which would facilitate loading precision-guided air-to-surface munitions. Features at the rear of the aircraft—including underwing actuator fairings, aft fuselage tailbooms, fins/strakes, axisymmetrical engine exhausts and the ventral fins—appear less compatible with stealth. The airframe configuration and aft fuselage shape is compatible with both thrust vector control (TVC) nozzle design, or a non-TVC rectangular nozzle designed for controlled infra-red emission patterns and radio-frequency stealth. 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/A-22A. Internal fuel capacity 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. There is also provision for an aerial refueling probe portside below the cockpit canopy.

Guided-weapons to be carried internally by the J-20 on four separate weapons bays include up to eight 16km-range PL-10 within-visual-range air combat missiles or 100km-range PL-21 ramjet-powered beyond-visual-range air combat missiles (jointly developed by CPMIEC and Leihua Electronic Technology Research Institute), along with the FT family of GPS-guided small-diameter bombs, especially the FT-6, which comes equipped with twin glide wings. The PL-21 will incorporate an on-board two-way data link to expand the missile's engagement envelope and support the increased HOBS capability. It will allow a third party, such as another combat aircraft or an AEW & C platform, to take control of the missile, allowing the firing aircraft to break away directly after launch. Two-way data links have the potential to increase weapon effectiveness during long-range engagements, since they could allow the missile to pass information on target characteristics and target behaviour to the launch platform as the engagement proceeds. Both the PL-10 and PL-21 will house a sub-millimetre wave-imaging fuze operating at frequencies above 200GHz to detect and classify the target aircraft and select the aimpoint for the 'mass-focussed' warhead to make sure more fragments hit their mark.

The integrated avionics suite will be of the open architecture-type and use the MIL-STD-1553B databus. The suite will incorporate features like automated data fusion, emission control and low-probability-of-intercept data links to build an operational picture for the pilot without giving away the aircraft's own location. Elements of the suite will include an active phased-array multi-mode radar now being developed by the China Electronics Technology Group Corp's (CETC) Nanjing Research Institute for Electronic Technology (NRIET, also known as the No14 Research Institute); retractable Hongguang-2 imaging infra-red search-and-track sensor (that includes a HgCdTe focal array with imaging infra-red capability) with 75km-range developed by Sichuan Changhong Electric Appliance Corp; Xian-based Cigong Group's holographic heads-up display and helmet-mounted display (the latter being a copy of the ZSh-7APN Sura-K HMD designed by the Arsenal Central Design Bureau State Enterprise of Ukraine); optronic missile approach warning-cum-countermeasures dispensing system developed by the Luoyang Optical-Electronic Technology Development Centre; and a quadruplex fly-by-wire flight control system, integrated communications suite, defensive aids sub-systems, low probability of intercept IFF transponder, TACAN, and an all-glass cockpit, all developed by the Suzhou-based AVIC Radar and Avionics Equipment Research Institute and the China Leihua Electronic Technology Institute (CLETRI, also known as the 607th Institute). The J-20's all-glass cockpit will feature twin ruggedised 8-inch by 20-inch panoramic active-matrix liquid crystal displays (PAMLCD) with both intuitive touch-screen and direct voice input usage, plus four smaller AMLCDs. The PAMLCD is an open system architecture-compatible dual redundant display that presents crisp, clear high-fidelity graphics and video overlays with a revolutionary infra-red touch screen human machine interface. A substantial portion of the J-20's avionics LRUs were developed in cooperation with Ukraine's Special Radio Device Design Bureau, Topaz Company, the Donetsk National Technical University, and SKB RTU. The internally-mounted directional jamming system, using active phased-array T/R modules, is being jointly developed by Southwest China Research Institute of Electronic Equipment, and the No51 Research Institute, which is also known as the Shanghai Research Institute of Microwave Equipment (SRIME). The same consortium is also developing the J-20's ADF and VOL/ILS receivers.— Prasun K. Sengupta.

J-20, a modified mig1.44

Similarities by Coincidence or More than Mere Coincidence?

I think it's the latter, the J-20 is a mere modification of the Mig 1.44.
