China's PLA gleans talent

The PLA underwent a dazzling round of reshuffles of senior officers in the past few months, including the job transfer of former deputy chief of General Staff Zhang Qinsheng. This new round of military personnel changes has to be understood in the broader context of China's new military revolution programme. The PLA is taking concrete measures, including reforms in the personnel system, to train military commanders with comprehensive skills in order to cope with demands and requirements of its "leap-frog" military revolution – and to retain its talent. From RSIS.

By Li Mingjiang for RSIS (20/08/07)

The Chinese People's Liberation Army (PLA) has launched a series of personnel changes since June this year, the most notable case being the swap of posts between Lieutenant General Zhang Qinsheng, deputy chief of General Staff of the PLA headquarters, and General Liu Zhenwu, commander of the Guangzhou Military Region. Within a few months, Beijing, Nanjing and Lanzhou Military Regions also had their new commanders. There were also quite a number of other personnel changes between departments of the headquarters and regional military units and between different regions.

Media commentators have noticed that this new round of reshuffles of senior officers demonstrates Beijing's consideration of training and promoting PLA leaders on the basis of expertise in military affairs, commanding skills, and relatively young age. These new leadership changes also indicate that the PLA is increasingly implementing its strategy of cultivating "multi-talented" military commanders to cope with the requirements of China's new military revolution and army building. One approach of fostering comprehensive skills for senior military leaders is to place them at positions or places where they have had no prior experience, a departure of the traditional way of usually letting them rise up in the same unit or sector. The Zhang-Liu swap represents such trend and the new importance of switching posts for the cultivation of comprehensive skills.
"External Transfer" as a stepping stone for possible promotion

In the Chinese military hierarchy, a deputy position of the four general departments of the PLA headquarters, which include the departments of General Staff, General Armament, General Political Affairs, and General Logistics, is equivalent to a full position at a Military Region or other military units that enjoy a Military Region status - the air force, the navy, the second artillery force, the National Defence University, and the Academy of Military Sciences. In this sense, LG Zhang's "external transfer" is a lateral move in position, with no change in ranking.

However, a deputy position at the Department of General Staff is usually preferred over a full position at a Military Region because it is often an inevitable step for possible promotion to the position of chief of general staff and ultimately to the membership of the Central Military Commission. With few exceptions, full-position leaders at a Military Region level usually have to go through the deputy positions of the general departments to move upward to the Central Military Commission. It looks like Zhang's transfer was a nominal demotion, but his case needs to be understood in the relevant context.

Normally, as is also true in the Chinese civilian sectors, an "external transfer" would take place for two purposes. First, the person to be transferred is about to retire or has no prospect of being promoted, or in some cases as an implicit penalty. The transfer is meant to vacate the position for a newcomer who may be seen as more promising in the eyes of the superior. Another possible cause is to transfer the person to a position out of the headquarters to gain more practical experience for possible promotion or assuming additional responsibilities in the future.

Zhang's change of job most likely represents the second pattern. Zhang served a long time career at PLA headquarters, including director of the Campaign Teaching and Research Office under the National Defense University (NDU), dean of studies at the NDU, and director of the Operations Department of the General Staff Department. Zhang is known as an expert in integrated war fighting and training, particularly under conditions of information technologies. He was promoted twice in two years, first assistant chief of staff in 2004 and then deputy chief of staff in 2006. His expertise on military operations under information conditions helped him in the rise.

In addition to his extensive expertise, Zhang performed fairly well first as assistant chief of staff and then as deputy chief of staff. He took over the responsibility of the retired General Xiong Guangkai to be in charge of the PLA's external affairs, including joint military exercises with foreign troops and China's military diplomacy. His job performance in these areas has been positively acknowledged by observers. Zhang is 59 years old, which, according to relevant PLA regulations, gives him at least 6 more years to stay at the full position of a Military Region level. Age requirement for membership in the Central Military Commission is a bit more flexible. In light of these factors, Zhang's temporary transfer to the Guangzhou Military Region likely will be a stepping stone for further promotion or at least being trusted with more additional important duties.
PLA's emphasis on comprehensive skills

The case of LG Zhang's transfer represents the importance that the PLA attaches to training senior leaders with multi-faceted skills. Zhang has already got extensive experience working at the PLA headquarters, but he lacks the actual experience of commanding the troops. His transfer is perhaps meant to provide an opportunity for him to obtain more practical experience and knowledge of field commanding. This is increasingly an approach of the Chinese military to cultivate senior military officers with multiple talents or comprehensive skills.

The emphasis on comprehensive skills is regarded as an indispensable part of the PLA's new "leap-frog" military revolution programme. Starting from the 1990s, Chinese senior military leaders called for the PLA to give priority to preparing for future local wars that would center on information technologies. A key component of future information-oriented war fighting is integration, which requires commanders to be knowledgeable in multiple areas and to sharpen their speed of response and standard of coordination.

As a matter of fact, this new round of military personnel changes for the purpose of building comprehensive skills is not something new. In the past few years, the PLA adopted unprecedented organizational measures at the very top level to ensure that multiple skills are available in military operations. For instance, the inclusion of the commanders of the air force and navy into the Central Military Commission and the promotion of generals of the air force and the second artillery force into the leadership of the General Staff were meant to allow the top decision bodies to have immediate access to all sorts of skills, not just the traditional lop-sided dominance by the army.

Chinese military experts have also vehemently called for an emphasis on comprehensive skills in education programmes at military universities. More recently, the PLA issued a publication called the Regulation on Attracting and Keeping Senior Professional and Technical Talents in the Military. This document vows to provide preferential treatments to civilians with professional skills and technological expertise if they want to work for the military. This is another indication that the PLA is attaching utmost importance to talent.
Conclusion: No turning back

The PLA is accelerating its new military revolution programme. In addition to introducing various hard weapons systems, the Chinese military is also paying unprecedented amount of attention to human talent. The job transfer of LG Zhang Qinsheng is representative of the PLA's attempt to cultivate senior officers with multiple sets of skills. No doubt, this practice is the road to the future for China's military.

US lawmakers get candid answers on military

China's military has been candid about its capabilities with visiting US lawmakers, allowing them to tour a navy destroyer and an artillery division that controls nuclear missiles, a senior American lawmaker said yesterday.

China's military has been candid about its capabilities with visiting US lawmakers, allowing them to tour a navy destroyer and an artillery division that controls nuclear missiles, a senior American lawmaker said yesterday.

Representative Ike Skelton, chairman of the House Armed Services Committee, said he and six other lawmakers were in China to promote "continued openness" with its military.

The People's Liberation Army, the world's largest standing army with 2.3 million members, is often criticized for lack of transparency and accused of routinely understating its budget.

But Skelton said Beijing had been open during his visit.

"We've received very candid answers about the capability of their military. They seem to be hiding nothing in our discussions with them," Skelton said. "I think it's beneficial to both China and the United States that there be strong military-to-military exchanges" to minimize misunderstandings.

The group met with several mainland officials and toured a naval destroyer at a base in Qingdao.

They were scheduled yesterday to visit the military sciences academy and the No 2 artillery division which controls China's nuclear and conventional missile forces.

They also planned to hold talks with Wu Bangguo, the head of the legislature.

In June, Skelton and the Pentagon accused China of intentionally understating what it spends on military programs. Its official defense budget for this year is about US$45 billion (HK$351 billion), but the "real" budget is between US$85 billion and US$125 billion, he said then.

Skelton avoided nearly all criticism of Beijing yesterday. ASSOCIATED PRESS

Re: Chinese Military News Thread

China's first defence chief to visit Japan in 10 years. There're talks of crisis hotline, sending a Japanese team to observe Chinese exercises & first ever PLAN ship to visit Japan.

Title : China tells Japan it is not a threat
By :
Date : 30 August 2007 1619 hrs (SST)

TOKYO - China's defence chief pledged Thursday that the rising power posed no threat to Japan as the countries tried to ease lingering tensions by agreeing to a crisis hotline and a first-ever Chinese ship visit.

General Cao Gangchuan is the first Chinese military chief to come to Japan in nearly a decade. He met with Japanese Prime Minister Shinzo Abe who has worked to repair rocky relations between Asia's largest economies.

"Those who speak of the theory of China as a military threat are ignorant of the true situation and their claims are unfounded," Cao later told a public address to invited officials and politicians.

He defended China's rising military spending, its nuclear arsenal and its January test shooting down of a satellite in space, which have all unnerved Japan.

"China does hold missiles and nuclear weapons. But they are for defence purposes," Cao said. "China wants to see total nuclear disarmament."

The general's visit to Japan was the first by a Chinese defence minister since February 1998, before relations between Tokyo and Beijing turned icy under former prime minister Junichiro Koizumi.

Koizumi drew China's ire by annually visiting the controversial Yasukuni shrine, which honours war dead along with war criminals who led Japan's militarism in Asia.

Abe, despite a conservative ideology, headed to Beijing days after taking office last year and has hailed the warming relationship as a key achievement.

"By inviting China's defence chief, we hope that we will further enhance relations between Japan and China," Japanese Defence Minister Masahiko Komura said as he welcomed Cao.

The two agreed to launch a study group to set up a military hotline. The two nations had a crisis in 2004 when Japan said a Chinese submarine intruded its waters.

"Both leaders agreed that they want to see it achieved as soon as possible," said a Japanese defence official who attended the talks.

Cao also invited Japan to observe a Chinese military exercise next month and agreed to send a Chinese ship on a first-ever goodwill visit to Japan in November or December, the official said.

Defence matters remain a thorn in ties between the two countries. Abe's government has joined the United States in voicing concern about China's soaring military spending.

"China is yet to explain fully the rationale behind the rapid pace of the increase in its military spending, such as what it wants to do and the goals," Komura told the Chinese general, according to the official.

"Japanese people would feel more at ease if China explained more," he said.

Cao said China had spent much of its increased military spending to raise salaries for soldiers and on uniforms, but added it was also modernising its military in line with global trends, the official said.

Japan has been officially pacifist since its defeat in World War II and relies on US protection, despite also having one of the world's best-funded armed forces.

Abe has championed a greater military role for Japan and has sought to ease potential unease from China and South Korea.

China has also in the past voiced concern about Japan's stance on Taiwan, which Beijing considers a province awaiting reunification, by force if necessary.

China Promises More Military Transparency

By AGENCE FRANCE-PRESSE, BEIJING
Please, Log in or Register to view URLs content!


China said August 2 it will begin reporting its armed forces budget to the United Nations and rejoin a global register of conventional arms amid foreign pressure for greater military transparency.

China said the moves were meant to show the world its commitment to military transparency, at a time when its massive armed forces expansion is causing alarm bells to ring in Asia and further afield.

“The Chinese government has decided to report annually to the Secretary-General of the United Nations basic data of its military expenditures for the latest fiscal year,” said a statement by Foreign Ministry spokeswoman Jiang Yu.

“This is a significant step on the part of China in further enhancing its military transparency, which fully demonstrates that China is committed to improving mutual trust with other countries in the military field.”

China will also resume providing data required under the United Nations Register of Conventional Arms starting from this year, the statement said.

The register is aimed at tracking transfers of arms worldwide. China quit the agreement in the late 1990s amid anger over U.S. arms sales to Beijing’s diplomatic rival Taiwan.

China, which already has the world’s largest armed forces with 2.3 million men and women in uniform, has dramatically beefed up its military in recent years, causing jitters in Asia and the United States about Beijing’s intent.

In March, the 2007 defense budget was raised a further 17.8 percent to 45 billion dollars.

The foreign worries spiked in January when China successfully destroyed a satellite in a new missile test, sparking fears of a race to weaponize space.

U.S. Vice President Dick Cheney said afterward the test contradicted China’s stated goal of a “peaceful rise.”

The U.N. conventional weapons registry requires countries to report their holdings of major weapons such as tanks, combat aircraft and missile systems as well as international arms transfers, according to the U.N.’s disarmament Web site.

Re: Chinese Military News Thread

Here is a news that try to give a list of current weapons in operation condition from China and Taiwan.

Balance in Taiwan Straits
by Andrei Chang
Hong Kong (UPI) Aug 31, 2007
During the past seven to 10 years, China's rapid buildup of military power has tipped the balance in the Taiwan Strait strongly in its favor.
Since 1999, when former Taiwan President Lee Teng-hui announced his "two states" theory -- daring to say that the People's Republic of China and the Republic of China are two different states, precipitating the PRC's aggressive stance against the island's independence -- there have been drastic changes in the balance of military power on the two sides. This includes the navies, air forces, and strategic campaign missiles, or ballistic missiles.

The Taiwanese air force has not added a single new combat aircraft since 1999. It still has 148 F-16 Block 15 MTU, 58 Mirage2000-5 and 130 IDF fighters in service. The total number of its third-generation fighters has remained around 336 over the past seven years. On the sea, the navy has added only four Kidd-class DDGs, the largest arms procurement since the Democratic Progressive Party came to power in 2000.

In terms of the buildup of ballistic missiles (surface-to-surface missiles, or SSMs), China has achieved a great leap forward both in the number of SSMs in its arsenal and in their overall quality. In addition to its DF-15 and DF-11 SSMs, which have been upgraded continuously over the years, television footage released by the official Chinese media shows there are at least one or two new types of short-range ballistic missiles now in operational service.

As far as the quality of the Chinese SSM is concerned, the export version of its B611M ballistic missile is now equipped with a GPS/GLONASS satellite positioning system, giving it a strike accuracy of around 50 meters (164 feet).

China's improved position in the air is evidenced by the changes in the quantity and quality of its third-generation combat aircraft from 1999 to 2007.

During that period, China's Su-27 SK remained steady at 48; its J-11 A/B went from two to 95; its Su-27 UBK's increased by 28; Su-30 MKK/MK2 from zero to 100; J-10A from five to 64; JH-7A went up from zero to 24; KJ-2000 from zero to 4 and KJ-200 from zero to two.

Based on these figures, the number of third-generation combat aircraft in the fleet of the People's Liberation Army Air Force was only a modest 55 in 1999, while in 2007 the number has jumped to 369. In 2008 it will further surpass Taiwan's fleet.

With the import of Su-30 MKK fighters, China's inventory of H-59ME and H-29TE TV-guided air-to-surface missiles, or ASMs; 1,500-pound Russian TV-guided bombs; H-31A anti-ship missiles; and H-31P anti-radiation missiles has also increased steadily over the last seven years. China has imported more than 1,000 RVV-AE active radar-guided air-to-air missiles, or AAMs, from Russia, while the number of AMR AAMs in the Taiwanese air force is no more than 120 now.

In addition, China continues to import a substantial number of RVV-AE AAMs every year. The critical change here is that in 1999, the PLAAF did not even have the capability to use such advanced AAMs as the PL-12RVV-AE AAM and the precision guidance land-attack weapons that they have now.

Given another two to three years, all the pilots of the PLAAF's 369 third-generation fighters will have accumulated flight time of more than 1,000 hours. Around 2009 or 2010, the overall quality of the military personnel ready to take to the air over the Taiwan Strait will be fundamentally reversed, in favor of the PLA air force.

In 1999 the PLAAF did not have the capability to engage in aerial early-warning operations. In 2007 there are already four plus two AWACS/AEW&C aircraft in operational service. Although these AWACS aircrafts have encountered such problems as electromagnetic disturbances and their training activities are less frequent than before, the PLA at least has the airborne warning and control system. The number of AWACS platforms currently operational in the PLAAF is equivalent to the number in Taiwan.

The PLAAF also has two refitted Y-8 electronic warfare aircraft, and other supporting electronic reconnaissance and countermeasure aircraft are under development. By contrast, the Taiwanese air force has had only one refitted C130 EW aircraft for years.

Since 1999 the PLA navy has prioritized and sped up the building of surface battleships over 4,000 tons, nuclear-powered submarines and conventional diesel submarines. From 1999 to 2007, it gained its first 094 SSBN and its first two 093 SSNs; the number of 956E/EM DDG (7,000-ton class) went from one to four; 051B DDG (6,000-ton class) stayed level at one; it gained two 051C DDG (7,000-ton class); two 052B DDG; two 053C DDG; four 054/A FFG; its KILO 887/636 SS went from four to 12 and 039A SS went from 1 to more than 10.

The most remarkable change is that the PLAN had only one type 051B and one type 956E missile destroyers (DDG), in 1999 that had a full-load displacement of more than 6,000 tons, whereas in 2007 it has 11 large surface battleships with a displacement of more than 6,000 tons, and two type 054A missile frigates (FFG) with a respective full-load displacement of more than 4,000 tons. By contrast, the only surface battleships in the Taiwanese navy with full-load displacement of more than 7,000 tons are the four Kidd-class DDGs.

In terms of its range of anti-ship missiles, the PLAN is also edging ahead of the Taiwanese navy. The PLAN's stockpile of anti-ship missiles with a range of over 200 kilometers (125 miles) has increased steadily, including the YJ6-2 and 3M-54E anti-ship missiles with respective ranges of 280 kilometers (175 miles) and 220 kilometers (around 135 miles). Those missiles give the PLAN the capability to launch long-range attacks on the sea and underwater as well. Besides, the PLAN has widely deployed the 180-kilometer-range YJ8-3 SSM on its surface battleships.

The PLAN's RIF-M, HQ-9 long range and HQ-16, Shtil-1 middle range ship-to-air missiles are also already in service. This means the overall range of ship-to-air missiles of the Taiwanese navy can no longer match that of the PLAN.

Unlike the PLA air force's aircraft, however, most of the new battleships of the PLA navy have only recently gone into operation and may encounter difficulties in combat applications. For instance, the delivery of 8 Kilo 636 submarines started only in 2005, and the type 052C "Chinese Aegis" DDGs have remained anchored at the Sanya military port for most of this year. This indicates that these new battleships may have encountered problems.

Particularly, the PLAN has not established an integrated combat system at sea. As for its Type 054A FFGs, they are still under construction, and two Type 054 FFGs were newly delivered in 2005.

It will take time for China to resolve the problems with its new defense equipment. Nonetheless, the military power balance in terms of quantity and quality of weapons between the two sides of the Taiwan Strait continues to tilt markedly toward the side of the PRC.

Re: Chinese Military News Thread

Here is a news about China alleged choosing the diesel submarine as a relatively more cheap solution for sea deterrent.

Defense Focus: Diesel sub wonder weapons
by Martin Sieff
Washington (UPI) Aug 31, 2007The diesel submarine may be the leading "Cinderella weapon" of the 21st century. It gets no respect in the United States or Russia. But China, India, France, Germany and Israel are all betting on it big time.
The diesel submarine is certainly not a sexy new technology like anti-ballistic missiles, global positioning satellites or lasers. It has been around as long as the submarine itself (British Adm. Lord John "Jackie" Fisher's bizarre experiment in giant steam-powered submarines, the notorious "K" boats of World War I, never got very far).

Diesel submarine technology was perfected more than 60 years ago in the great ocean-worthy U.S. Navy fleet of subs in World War II and in the German Type XXII and XXIII U-boats that became operational towards the end of the war.

However, the development of nuclear submarines, first by the U.S. Navy in the 1950s and then by the Soviet Union, appeared to make the diesel sub as obsolete as the bow and arrow became after the mass production of firearms. Adm. Hyman Rickover, the feisty father of America's nuclear navy, hated them like poison. So did his successor admirals.

Thanks to their procurement policies, there is not a single shipyard left in the entire United States that makes them anymore. But in other major nations, the old diesel sub is making a remarkable comeback.

Israel has already deployed three German-built Dolphin diesel submarines to carry nuclear-armed cruise missiles to provide it with a survivable second-strike capability to deter Iran or other nations from the temptation of carrying out a pre-emptive first strike with nuclear weapons, and it has ordered at least two more -- both also from Germany.

France is doing good business building its Scorpion submarines for export too, and India is planning to deploy Scorpions with cruise missiles as a deterrent against Pakistan similar to the Israeli concept.

But the biggest enthusiast for diesel subs is China, which is building its own: In 2006 it built 14 of them to one U.S. -- nuclear-powered -- new submarine.

China is building a mixed, or balanced, submarine fleet. It has also invested in bigger nuclear-powered strategic submarines to carry a survivable second-strike ballistic missile deterrent primarily aimed at the United States. But it is pouring major resources into its conventional submarine fleet as well. Why?

Diesel subs certainly do not have the limitless range and endurance for long-term operational deployment that nuclear subs do. But in conventional war, they have a lot of advantages as well.

They can operate far more easily in littoral or offshore, shallow waters, and being much smaller than nuclear submarines gives them a potentially huge operational advantage in key enclosed potential combat regions like the eastern Mediterranean Sea, the Red Sea and the Persian Gulf.

Also, China's procurement policies and its overwhelming concentration of force in its southeast coastal region leaves no doubt that Chinese operational planners see their most likely conventional enemy as being the U.S. Navy and Air Force in any eventual conflict over the status of Taiwan.

In this context, having a very large conventional diesel submarine fleet makes a lot of sense. Conventional diesel subs can pose a formidable threat to nuclear aircraft carriers operating within operational range of their home ports, as the Chinese sub fleet in the western Pacific and the Taiwan Strait would be doing in such a conflict.

U.S. anti-submarine warfare, or ASW, capabilities are superb, the best in the world. But they were overwhelmingly developed to locate and destroy bigger Soviet or Russian strategic and attack subs that were nuclear powered. A lot of smaller, cheaper diesel subs operating as underwater wolf packs would stand a much better chance of overwhelming the ASW defenses of U.S. carrier battle groups than throwing just two or three nuclear attack subs against them at a time would.

For Israel and India, the calculus is a different one: Israel simply cannot afford to buy nuclear subs, and they would be too big and therefore easy to detect in the relatively shallow Mediterranean anyway.

Nor does it need big nuclear-powered platforms like the U.S. Ohio class strategic subs or the old Soviet-era Typhoons, or even the somewhat smaller new nuclear powered Russian Borei class to carry its second-strike weapons.

Israel can't afford and does not need long-range submarine-launched ICBMs anyway. Iran, Syria and its other potential enemies would all be within range of much smaller intermediate-range cruise missiles that could be launched from a conventional sub. So the Jewish state has sensibly invested in German U-boats as its main line of defense. One wonders what Grand Adm. Karl Doenitz would have thought about it all.

In 1982 the British nuclear submarine HMS Conqueror proved the conventional operational potency of the nuclear attack submarine by sinking the Argentine heavy cruiser General Belgrano during the Falklands, or Malvinas, War. Future wars, however, may see that dynamic reversed with enormous nuclear surface ships hunted by fleets of a weapon employed in both world wars that was supposed to have been superseded half a century ago: the non-nuclear diesel submarine.

Re: Chinese Military News Thread

Here i found a news about China striving in the way of advanced propulsion scramjet for aerospace and military systems.

China is starting to ramp up its scramjet propulsion work—an initiative that will benefit high-speed missile programs while also helping the country to develop advanced aerospace materials, greater computational capabilities and a cadre of young engineers who have matured as a result of cutting-edge engine and aerodynamic challenges.

Building on its ramjet experience, China is embracing the much more difficult task of developing Mach 5 air vehicle concepts in which propulsion and aerodynamics are highly coupled.

As part of this effort, an integrated scramjet model is about to begin testing at up to Mach 5.6 in a new wind tunnel in Beijing.

In addition to the technology and engineering experience to be gained, the mid-term military payoff is likely to be more advanced high-speed tactical and medium-range Chinese missiles, especially for antiship warfare that could threaten U.S. aircraft carriers in the Pacific or operating in support of Taiwan.

“China has the greatest potential to compete militarily with the U.S. and field disruptive military technologies that could, over time, offset traditional U.S. military advantages,” the 2006 Pentagon Quadrennial Review said about overall Chinese military technology initiatives.

And over the next several decades, the scramjet work could eventually provide China with a tactical hypersonic global-strike capability beyond the country’s strategic ballistic missile force. The U.S. has similar goals for its own growing scramjet program.

The Chinese allowed a peek into multiple aspects of their scramjet efforts at the recent American Institute of Aeronautics and Astronautics Joint Propulsion Conference in Cincinnati. Chinese engineers from several research facilities presented about a dozen papers on their scramjet developments, as well as details on the new wind tunnel.

At the same forum, their papers revealed new rocket propulsion research, including work on hybrid systems that use a combination of propellants easier to handle and store than most propellants in wider use today. New insight also was offered on Chinese solid rocket motor technology work, important for both missile and space launch applications.

The Cincinnati meeting differed from a traditional U.S. industry gathering, because nearly a dozen engineers from Iran also submitted papers on Iranian solid and liquid rocket technologies. The Iranian engineers are based at the Sharif University of Technology and the KNT Technical University, both in Tehran. They apparently did not deliver the papers in person. However, as participants, the Iranians have access to all of the highly detailed U.S. aircraft and rocket propulsion presentations made at the conference.

A scramjet (supersonic combustion ramjet) flies at Mach 5 or faster using hydrogen fuel and oxygen out of the air for oxidizer. The engine must combine an advanced ramjet that changes configuration to swallow supersonic flow above about Mach 4.

Advanced ramjet technologies are also important for scramjet development, and the Chinese have been active in this area for decades.

Ironically, one the more interesting historical papers presented at the forum was a detailed description of how the U.S. Air Force and Lockheed combined top-secret ramjet propulsion technologies with segmented solid rocket boosters for the Mach 3 D-21B reconnaissance drones that were launched by modified SR-71s and B-52Hs in the late 1960s (see center photo). The D-21B was specifically developed to gather intelligence over China.

This was the first time details on the segmented rocket booster portion of the D-21B program have been presented publicly, says Robert Geisler of Geisler Industries, who led the analysis with retired Pratt & Whitney and ATK Tactical Propulsion engineers. Segmented boosters use individual circular sections like space shuttle solid rocket motors.

China already has such segmented solid rocket motor and ramjet capabilities today, but scramjets are a much greater challenge.

Although nowhere nearly as advanced as U.S. scramjet work, Chinese activities in this discipline will give the Defense Dept. additional impetus to argue for strong, ongoing U.S. hypersonic propulsion funding. Diverse U.S. technology programs are already underway to support development of the X-51 scramjet test vehicle (AW&ST July 23, p. 23).

As part of the Chinese effort, the engineers say new analytical centers are also being developed. For example, a Hypersonic Propulsion Test Facility has been built to support the scramjet program, according to Xinyu Chang, a senior researcher at the Laboratory of High-Temperature Gas Dynamics in Beijing, where the HPTF is located. Gas Dynamics lab research is specifically oriented to “the development of hypersonic flight vehicles, both aeronautics-and space-related,” according to data from the facility.

Broad studies there are “devoted to the fundamentals of hypersonic and high-temperature gas dynamics including detonation phenomena, supersonic combustion, chemical reactions, shock-wave/vortex interactions and thermal-chemical flow characteristics.” The lab helps lead several Chinese technology programs for scramjet propulsion. This includes basic hypersonic vehicle designs that could mate with a scramjet engine, as well as computational fluid dynamics work to assess the challenge of coupled ramjet/scramjet inlet flow fields at the front of the vehicle.

Scramjet ignition technology and work on cooling the internal walls of a scramjet are also being assessed, the Chinese say. Computer modeling of scramjet combustion instability is also being modeled.

“At the present time, the emphasis on rocket-based combined cycle [RBCC] scramjet research has gradually transferred from research and performance studies to some ground experiments and structures design,” says Wang Houqing, a researcher at Northwestern Polytechnical University in Xian. NPU is one of China’s top aerospace research centers.

“A copper model scramjet is ready for testing” in the new Gas Dynamics Laboratory facility, says Xinyu.

“The facility is to provide high enthalpy [thermal dynamic] model scramjet testing,” he says.

The facility uses a hydrogen/air and oxygen replenishment combustion heater with a flow rate of 3.5 kg./sec., with temperature capabilities up to 2,000K. It can generate test velocities up to Mach 5.6, according to Xinyu.

Many different scramjet combustor configurations have been tested so far, he says. But the new facility will allow complete scramjet engine model configurations to be evaluated instead of just the combustor alone.

Other Chinese scramjet research presented at Cincinnati included:

•Aerodynamic performance of Chinese waverider designs integrated with an inlet. “Simulation studies were conducted to investigate forebody-inlet-isolator performance in an airframe-scramjet integrated hypersonic vehicle,” according to Liu Zhenxia, also at NPU.

•Multicode computational fluid dynamics runs for coupled ramjet/scramjet inlet flowfields. This work models the transition from “ram” to “scram” propulsion. The research is underway at the Beijing University of Aeronautics and Astronautics.

China hacked Pentagon, leaked report says
Tom Jowitt, Techworld

Chinese Army blamed for computer espionage
Leaked reports of an internal investigation suggest the Chinese military has been blamed for a hack into a computer network belonging to the Pentagon.


The Financial Times, citing unnamed current and former US officials, said the hack of US Department of Defense systems took place in June.

While the Pentagon declined to say who was behind the hacking, which led to the shutdown of a computer system serving the office of Defense Secretary Robert Gates, officials told the FT newspaper that it was China's People's Liberation Army.

"The PLA has demonstrated the ability to conduct attacks that disable our system," the newspaper quoted a former US official as saying. One senior US official reportedly said the Pentagon had pinpointed the exact origin of the attack.

The paper quoted another person familiar with the event as saying there was a "very high level of confidence... trending towards total certainty" that the PLA was responsible.

The paper said both the US and Chinese militaries were widely assumed to conduct computer espionage on each other, however the June hack has raised concerns to a new level "because of fears that China had shown it could disrupt systems at critical times".

However, the Chinese are vigorously denying the claim, dismissing it as a product of "Cold War" thinking.

"The Chinese government has consistently opposed and vigorously attacked according to the law all internet-wrecking crimes, including hacking," said Chinese Foreign Ministry spokeswoman Jiang Yu at a regular news briefing on Tuesday.

"Some people are making wild accusations against China ... These are totally groundless and also reflect a Cold War mentality."

Last week, Chinese hackers were accused of infiltrating German government computers. Angela Merkel, the German chancellor, apparently raised the issue with China's premier, Wen Jiabao, in a visit to Beijing. The Der Spiegel newspaper claimed that the hackers had been traced to Guangzhou and Lanzhou, which are both centres of operation for the People's Liberation Army.

There seems to be little doubt that the PLA probes US networks, just as the US does the same to Chinese systems. And it is not just foreign governments that the Pentagon has to worry about.

Back in July, Gary McKinnon, the ex-systems administrator accused of conducting the biggest military hack of all time, won the right to have his case against extradition to the US heard by the House of Lords.

McKinnon, accused of causing $961,000 worth of damage to computers by hacking into systems belonging to the Pentagon, NASA and the US military from his home in North London, could face a life sentence in jail with no chance of repatriation if he is extradited to the US.

We've known for a while now that China has invested heavily in cyber warfare. Wheter this was a defeat or a victory for them is not really known because we don't knwo how much info they got but still this confirms that they have a lot of capability in this area.

Re: Chinese Military News Thread

Amazingly a ROCA official maintained recently in a statement about the mainlands cyberwarfare capabilities that Taiwan would be pretty safe for the time being since ROCA's own capabilities were definitely superior in this regard!:confused:

Well, this could be a sad example of excessive ignorance and hubris or Taiwan is just indeed the globes sole cyberwarfare hyperpower! (...America watch out: Taipeh knows already more than you know...:roll:)

China's military tests sophisticated real-time data system

BEIJING, Sept 19 (AFP) Sep 19, 2007
The Chinese military has begun a two-day drill testing a system that provides commanders real-time battlefield data, signalling the continued modernisation of the nation's massive armed forces.
The exercise is part of an ambitious effort to improve military information collection systems, one of the main shortfalls of the otherwise rapidly modernising People's Liberation Army, the Xinhua news agency reported on Wednesday.

"We are trying to catch up with the advanced countries. It's a very complicated system, as it involves every military unit," Xu Guangyu, a retired Chinese general, told AFP.

"I think we need at least ten years to catch up with the world's most sophisticated nations," he said.

The drill, dubbed "North Sword 0709", was carried out at the Zhurihe training base in north China's Inner Mongolia Autonomous Region, the nation's largest military training field, Xinhua said.

Each of the 2,000 participating soldiers is equipped with an electronic device constantly beaming information back to headquarters about battlefield conditions, Xinhua reported.

This allows commanding officers to have precise information at any time about ammunition levels, food consumption and casualties among units under their command, according to the agency.

"The system could let us know the exact conditions our troops are under in combat... and when we should support them with logistics," said Zhang Jixiang, a senior officer taking part in the manoeuvre.

This particular effort targets an area of modern military technology aimed at enhancing what is known in the specialist literature as "battlefield awareness," said Robert Karniol, a Bangkok-based independent military analyst.

"The better commanders know what's happening on the battlefield, the better they can apply their resources, whether in people or in firepower or in mobility or in logistics support," he said.

No outside observer knows for sure when China decided to improve its capabilities in this particular field.

However, it is widely accepted that the first Gulf War of early 2001, showing off the immense superiority of the tech-savvy US armed forces, was a milestone in Chinese thinking on the issue.

"You can say with some certainty that the first Gulf War accelerated the process," said Karniol.

China's 2.3-million-strong military has seen its 2007 budget rise 17.8 percent from last year, and is now going for quality rather than quantity.

It is focusing considerable attention on the need to adopt high technology as means to enhance its battle efficiency, apparently with some success.

Recently, reports suggested that hackers from the People's Liberation Army had caused a shutdown of a computer system serving the office of US Defense Secretary Robert Gates.

Similar hacker attacks linked to the Chinese military have been reported by other western countries as well.
