Diverterless supersonic inlet (DSI), according to Wikipedia, is less complex, more reliable and lighter than other inlets. In addition, Wikipedia says “DSIs also crucially improve the aircraft’s very-low-observable characteristics (by eliminating radar reflections between the diverter and the aircraft’s skin). Additionally, the ‘bump’ surface reduces the engine’s exposure to radar, significantly reducing a strong source of radar reflection because they provide an additional shielding of engine fans against radar waves.”
Of the six fighter jets with DSI in Wikipedia’s list, all are Chinese ones (J-10B, JF-17, J-20, J-31 and JL-9) except America’s F-35.
Therefore, China’s mastery of DSI technology is well-known in the world. There is no need for mil.huanqiu.com to show off the above photos of J-20’s DSI.
However, as Chinese military fans are much interested in J-20’s functions and performance, they have taken and posted photos of J-20’s DSI to show their pride in China’s success. They are especially happy in doing so as Chinese government is not willing to do so.
That makes pro-US people, especially military fans, unhappy. Some of them give elaborate description of F-35’s superiority and exaggerated J-20’s weakness.
That certainly makes pro-Beijing readers unhappy. However, according to my experience, people indeed have helped me a lot by pointing out my errors and shortcomings no matter whether their intention is kind or not. I will be very happy if the pro-US readers point out J-20’s shortcomings. However, as they have no source of information, they are unable to effectively do so.
That is really a pity.
If they have professional knowledge, they may be able to find something unsatisfactory in the photos taken by Chinese fans that aimed at showing off J-20’s superiority.
Maybe they do have such knowledge, but Chinese fans refrain from posting photos that reveal anything unsatisfactory in J-20.
Indeed, pro-US readers should not be unhappy. They should know very well that those Chinese fans have PLA internal sources so that they need not wait day and night by the side of Chinese airfields to take photos of J-20’s test flights. The internal sources reveal to the fans before the tests and told them the time and place they can take photos satisfactorily and what they should included in their photos to show off J-20’s advantages.
Pro-US military fans simply have no such access to enable them to take photos of J-20’s test flights to find and show off J-20’s shortcomings. What a pity! They cannot help China improve J-20 by making China aware of J-20’s shortcomings.
In comparison, US military is better. They are too anxious to show off F-35. That perhaps scares its enemy. However, it enables its enemies to know in designing their rivals to F-35 what they need to include and what not. That saves them much costs and time. Moreover, it enables them to learn from F-35’s good design, functions and performance and include F-35’s good design in their designs.
It is good for US military that they can learn F-35’s shortcomings from unfavorable comments on what they have disclosed about F-35, but bad that others may copy F-35’s designs and know what their aircrafts shall have to deal with F-35.
China, however, keeps strict confidential information about J-20. It follows Sun Tzu’s teaching: The art of war is an art of deception; therefore show what you are unable to do when you are able to and you are not to use your military when you are …”

Popular Science’s article “China’s new aircraft carrier hints at the future of its navy” says China’s third homegrown aircraft carrier will be a 90,000 to 100,000-ton nuclear one with electromagnetic catapult that enables it to carry 70-100 stealth fighter jets, AEW&C aircrafts and aerial tanker with maximum takeoff weight of 50 tons and helicopters.
The following is the full text of the article:
China’s new aircraft carrier hints at the future of its navy
The Liaoning carried at least three helicopters, eight fighters, three destroyers, two frigates, and a refueling ship.
By Jeffrey Lin and P.W. Singer January 13, 2017
Last month China reported that its aircraft carrier Liaoning was ready to start operational service. The country’s navy provided proof on Christmas Day, sending out its first carrier battle group (CVBG) through the Miyako Straits, around Taiwan, and into the South China Sea, launching and recovering aircraft along the way.
Looking ahead to 2030, the next Chinese carrier will likely look very similar to the Liaoning CVBG, with updated destroyers and frigates that provide a more advanced layered defense and missile strike system. It will likely be accompanied by an arsenal of drones.
And then come the nuclear-powered carriers of the Type 003 Chinese aircraft carrier. The Type 003 itself would likely have a displacement of around 90,000-100,000 tons and carry anywhere from between 70-100 helicopters and fixed wing aircraft, and have multiple aircraft elevators and a single island superstructure. With a nuclear-powered reactor, the Type 003 could reach speeds in excess of 30 knots. The reactors could also provide the power for electromagnetically assisted launch system (EMALS) catapults (the preceding conventional Type 002 carrier may use steam catapults). EMALS catapults have improved efficiency and are less maintenance intensive than steam catapults.
The air group will likely still use J-15 fighters for multi-role purposes, along with an electronic warfare mission variant. For dedicated air superiority mission, the air group could also have fifth-generation stealth fighters, most likely navalized versions of either the J-31 or even the J20. The EMALS catapult could allow the Type 003 to launch aircraft with a takeoff weight of up to 50 tons, including aerial tankers, airborne early warning aircraft (especially useful to guiding long range missiles against distant aircraft), anti-submarine warfare (ASW) planes, smaller cargo planes and strike aircraft. Given Chinese interest in unmanned vehicles, the Type 003 could come with a UAV for surveillance and reconnaissance. The Type 003’s air group will also have helicopters for ASW and search and rescue missions.
The CVBG’s escort elements will likely consist of Type 055 destroyers and a future Chinese frigate (Type 057?) with an integrated mast. The improved Type 055, upgraded from the current hulls under construction, would have integrated electric propulsion system to increase onboard power generation for sensors and direct energy weapons. It will likely also be armed with over a hundred long-range anti-air and surface attack missiles, in addition to carrying helicopters. Given Chinese interest in unmanned naval vehicles, those surface combatants would likely carry UAVs, UUVs, and USVs for mine countermeasure. For underwater escort, the accompanying submarine would likely be a Type 095 nuclear attack submarine, stealthier and more heavily armed than current Chinese attack boats.
Depending on the CVBG mission profile, amphibious warfare ships like the Type 071 landing platform dock and landing helicopter docks be deployed to help disembark Chinese marines and air cavalry forces.
Years of operational experience are still needed to make the Liaoning, and the rest of the PLAN, ready for combat and other intensive carrier operations. But the PLA is now off to an important start with the Liaoning, and they have bigger plans for the future.

Deng Xioping invented the idea that there shall be a core in the collective leadership of the Chinese Communist Party (CCP) who has the final say. His Southern Tour showed that he as the core had omnipotent power to fire any official who did no conduct his reform and opening-up though he had no official posts in either the government or the party.
As the core has the power as omnipotent as an emperor in China’s feudal dynasty and as the core is CCP’s, I called the new Chinese political system initiated by Deng as the CCP Dynasty in my book Tiananmen’s Tremendous Achievements.
I point out in my book that with the third of his Three Representatives, Deng’s successor as the core Jiang Zemin turned CCP into a party of the whole people instead of the proletariat while Hu Jintao, Jiang’s successor as CCP general secretary has made CCP a party that adopts Chinese sage Mencius’ democratic doctrine of “putting the people first” with his Scientific Outlook of Development.
As Deng Xiaoping theory (about the core), Three Representatives (about CCP being the party of the whole people) and Scientific Outlook of Development (about putting the people first) have all been written into CCP’s constitution, when Xi Jinping has successfully succeeds Jiang as the core of CCP’s collective leadership, CCP Dynasty has firmly established.
According to American great statesman Abraham Lincoln’s famous Gattysburg Address, in a democracy there is the “government of the people, by the people, for the people”, I regard CCP Dynasty as a democracy with Chinese characteristics as there are two factors of democracy in CCP Dynasty: government of the people (the third of Three Representative) and for the people (putting the people first in Scientific Outlook of Development).
In China’s feudal dynasty there was the well-known saying: “Everywhere under the sky is ruled by the emperor”. Now, in CCP Dynasty, “everywhere in China is ruled by CCP”.
If one knows that China’s political system is CCP Dynasty, one will not be surprised by Reuters’ report today on China’s Chief Justice’s statement on Chinese courts not independent from CCP and rejection of Western constitutional democracy and separation of powers.
Comment by Chan Kai Yee on Reuters’ report, full text of which is reblogged below:
China’s top judge warns courts on judicial independence
China’s courts must firmly resist the western idea of judicial independence and other ideologies which threaten the leadership of the ruling Communist Party, the country’s top judge was reported as saying by state-run Chinese News Service.
People’s Courts at all levels must disregard erroneous western notions, including constitutional democracy and separation of powers, Chief Justice Zhou Qiang was reported by the news agency as saying at a Supreme People’s Court meeting on Saturday.
China has in recent years unveiled legal reforms such as those aimed at giving judges more independence and limiting local official’s influence over courts, but courts are not independent and ultimately answer to the party leadership.
Since he took office in March 2013, President Xi Jinping, who has a doctorate in law, has vowed to put “power within the cage of regulations” and called for judicial independence under the party.
Zhou’s comments on Saturday come after the country’s anti-graft watchdog said that a mechanism independent of the Communist Party to keep officials in check cannot exist in China.
At an annual meeting earlier this month, the Central Commission for Discipline Inspection (CCDI) pledged to create a national supervisory commission and a corresponding national law, as part of a move to reform the oversight system for thousands of party officials.
But the reforms would stop short of placing power outside the party, CCDI officials said at a briefing on Jan. 9.

China’s deployments of technological assets to the South China Sea may be aiding its efforts to dominate one of the world’s most contested waterways.
Other regional claimant states lack the capabilities to compete with China’s maritime technology, and the U.S. deploys its strategic assets on a non-permanent basis.
China, on the other hand, has deployed radars, drones, and satellites to significantly boost its ability to monitor its “territorial waters” in the South China Sea.
“China can use their technology or use defense to claim that we have strengthened our holding or our control, or administration or even our scientific research in the South China Sea,” Yun Sun, senior associate in the East Asia Program at the Stimson Center, told Voice of America.
In the long run it is one way that could matter,” she added.
She stressed that while China’s extensive claims to the South China Sea were discredited by the Permanent Court of Arbitration in The Hague this past summer, “the Chinese can come up with a list of the equipment they deployed in the region and show that as evidence of sovereignty.”
Chinese deployments also give China the ability to monitor regional activities in a way that other states cannot.
China launched the Gaofen 3 satellite in August 2016 to “play an important role in monitoring the marine environment, islands and reefs, and ships and oil rigs,” the China Daily wrote, citing Xu Fuxiang, the project director.
The satellite “will be very useful in safeguarding the country’s maritime rights and interests,” the report added.
China revealed in September last year that it can now deploy domestically-produced drones to carry out “complicated surveillance” in the South China Sea and around the Senkaku/Diaoyu Islands in the East China Sea.
“Reefs and islands are an important parts of our national territory. Precise information of their geology is crucial evidence for the demarcation of territorial waters and for safeguarding national maritime interests and security,” Li Yingcheng, general manager of China TopRS Technology Co. Ltd., an affiliate with the Chinese Academy of Surveying & Mapping, told the People’s Daily.
The report called the drones “especially stealthy.”
China is also working on a defensive wall beneath the waves. At a Chinese underwater robot exhibition in March 2016, China State Shipbuilding Corporation (CSSC), which builds a majority of China’s naval vessels, introduced plans for the construction of an“underwater Great Wall” for anti-submarine warfare purposes.
The project will rely on seabed sensors and unmanned underwater vehicles like the U.S. naval drone recently seized by the Chinese navy in international waters.
“We’re faced here with a very a non-uniform, uneven proliferation of new technologies in the South China Sea,” Collin Koh, a research fellow focusing on maritime security at Nanyang Technological University in Singapore, told VOA reporters.
China’s military deployments often receive the most attention; however, the non-military strategic assets appear to also be impacting the situation in the South China Sea.

Reuters says in its report “China and Vietnam to ‘manage’ differences over South China Sea: communiqué”, “China and Vietnam pledged on Saturday to manage their differences and safeguard peace in the South China Sea, in a joint communique issued during a visit to China by Vietnamese Communist Party chief Nguyen Phu Trong.”
In addition, “In the joint communique on Saturday the two sides agreed to continue to ‘fully and effectively’ implement the Declaration on the Conduct (DOC) of Parties in the South China Sea and strive for the early conclusion of a Code of Conduct (COC) on the basis of consensus in the framework of the DOC.”
The DOC already signed by China and ASEAN and the COC to be finalized and signed are aimed at peaceful solution of disputes in the South China Sea. It proves China’s success in subduing the enemy with diplomacy.
It has won over the Philippines and the victory of Nguyen Phu Trong’s détente faction in Vietnamese communist party’s election over the hardline faction that caused standoff in the South China Sea over China’s drilling rig there proves peaceful solution is much more popular even in Vietnam.
That is especially true as Vietnam talked up in public statements its traditional friendship with China in spite of the fresh memory of China’s war with Vietnam in 1979. Vietnam’s military build-up mentioned in Reuters’ report proves the memory of the war is indeed fresh in Vietnamese people’s mind. Still they prefer peace and have been won over by China’s peaceful diplomacy.
Now only the US wants to subdue others with war, but as military solution is unpopular in the world, the US has failed to get ASEAN’s support for its confrontation with China in the South China Sea.
Poor United States, it goes nowhere in the South China Sea in spite of its strongest military because it has the weakest diplomacy.

China and Vietnam to ‘manage’ differences over South China Sea: communique
China and Vietnam pledged on Saturday to manage their differences and safeguard peace in the South China Sea, in a joint communique issued during a visit to China by Vietnamese Communist Party chief Nguyen Phu Trong.
After “candid” discussions, the two countries agreed to “manage well their maritime difference, avoid actions that complicate the situation and escalate tensions, and safeguard the peace and stability of the South China Sea”, said the communique published in full by China’s state news agency Xinhua.
China claims almost all of the South China Sea, where about $5 trillion worth of sea-borne trade passes every year. Brunei, Malaysia, the Philippines and Taiwan, in addition to Vietnam, also have claims in the sea, believed to have rich deposits of oil and gas.
In public statements, Chinese and Vietnamese leaders regularly talk up their common interests as “traditional” friends and neighbours, but conflicting claims of sovereignty in the South China Sea have become a major source of tension in recent years.
In the joint communique on Saturday the two sides agreed to continue to “fully and effectively” implement the Declaration on the Conduct (DOC) of Parties in the South China Sea and strive for the early conclusion of a Code of Conduct (COC) on the basis of consensus in the framework of the DOC.
In September, Chinese President Xi Jinping told Vietnam’s visiting prime minister their common interests far outweighed their differences, and called for their dispute in the South China Sea to be resolved through talks.
Vietnam is in the midst of a quiet military build-up which analysts say is designed as a deterrent, to secure its 200 nautical mile Exclusive Economic Zone, as China grows more assertive in staking its claims in the South China Sea.

ABC News published an article titled “Analysis: Russia’s Far East Turning Chinese” on flood of Chinese immigration into Russia’s Far East.
Russia and China have a long history of hostility. The article says, “Russia took the territory in 1858 and 1860 with the Treaties of Aigun and Peking, respectively. Of all of the unequal treaties forced upon the Qing dynasty by outside powers in the 19th century, these are the only two China has not managed to overcome. China and Russia signed a border agreement in 1999, but the Beijing government has never formally accepted the Aigun and Peking treaties.”
The article describes Russia’s worry about Chinese illegal immigration into Russia’s Far East. In fact, those who know the history of Chinese immigration do not worry. In the 19th and 20th centuries, Chinese immigrants flooded Southeast Asia. They now dominate the economy of some countries there but have never turned those countries Chinese. Singapore people are more than 80% ethnic Chinese, but they are pro-America instead of pro-China.
However, there is indeed danger of war as lots of Chinese want a war with Russia to recover the 2 million square km of land in Russia’s Far East that China ceded to Russia under the two treaties mentioned in ABC News’ article.
Thanks to Obama, the war will be prevented as due to Obama’s pressure to contain both Russia and China, the two countries’ wise leaders have turned the two countries into good friends and indeed de facto allies with diplomacy that makes them strong enough to subdue the US with joint force.
Moreover, the diplomacy of win-win cooperation has turned potential enemies into good friends.
China follows its gifted strategist Sun Tzu’s teaching that subduing the enemy with diplomacy is better than with war. Putin seems also to have such wisdom. The two countries both turn a blind eye to the illegal immigration.
In fact Putin wants China to cooperate with it in developing Russia’s Far East as no Russians want to go there but Chinese people are fond of going there. Putin adopts the policy of allowing Chinese immigrants who have married Russian to naturalize. That will be good win-win cooperation.
Now, Putin has removed Russian border guards along Russian border with China in Russia’s Far East to allow Chinese immigrants free entry. The photo on top shows that a scarecrow is guarding the border at a border post.
Subduing the enemy with diplomacy is better than with war! Putin and Xi Jinping know that but Obama does not. I hope Trump does.
