L'avion spatial chinois Shen Long : une réponse au X-37B américain
La mission réussie de la mininavette américaine X-37B laisse perplexes les responsables russes et chinois, tant les objectifs de ce programme sont flous. Si les Américains définissent leur engin comme un démonstrateur de technologies pour l'accès à l'espace, Russes et Chinois n'écartent pas la possibilité d'une orientation militaire.
Officiellement, l’avion spatial américain X-37B est présenté comme un démonstrateur de technologies liées à l’accès à l’espace et de nouveaux capteurs pour une utilisation sur de futurs satellites espions, mais ses objectifs restent vagues. X-37B est doté d’une soute (impossible de savoir ce qui sera largué ou récupéré une fois en orbite) et peut être lancé en toute discrétion, sous la coiffe d’un lanceur. Face à une éventuelle utilisation militaire, si les Russes en sont au stade des menaces verbales, les Chinois ont eux un prototype en préparation depuis plusieurs années, qui devrait réaliser un vol d’essai orbital d’ici quelques années.
Lors de son vol d'essai, le profil de la mission de l'X-37B s’est apparenté à celui d’un satellite espion avec des temps de revisite très courts. Pour ce que l’on sait, il a effectué des passages répétés au-dessus de pays sensibles comme l’Irak, l'Afghanistan, l’Iran et la Corée du Nord. Il s’est même approché de la Station spatiale sans que l’on sache à quelle distance, ni si ses occupants ont pu le voir. Enfin, son retour sur Terre s’est déroulé de nuit de façon à ne pas montrer son angle d’entrée.
Une fusée aéroportée chinoise
Ce programme qui trouve ses origines au début des années 2000 est étroitement surveillé par la Chine qui n’a pas attendu le vol inaugural de 2010 pour réfléchir à un engin similaire. Le projet d’avion spatial chinois commence en 2000 avec les premières études théoriques qui débouchent sur une revue de définition et de conception en 2005. Un premier vol d’essai est réalisé à la fin 2007 mais l’engin ne s’aventure pas dans l’espace. À l'époque, une tentative de vol orbital était prévue en 2010.
Quant à ses performances, il est difficile de se prononcer tant le projet est confidentiel. Seule différence notable par rapport à son homologue américain, il est lancé par un avion, comme le sont les fusées Pegasus d’Orbital Sciences. Pour faire bonne figure, la Chine rappelle que ses ambitions initiales visaient la maîtrise de technologies pour des avions commerciaux capables de voler à des vitesses au-delà de Mach 10, la militarisation du programme ayant ensuite été motivée en réponse aux avancées américaines.
Des avancées significatives
Reste que la mise au point de cet engin nécessite des progrès technologiques significatifs au premier rang desquels figurent la possibilité de réutilisations, la propulsion, l'aérodynamique et la protection thermique. Et nul ne sait où en sont les Chinois dans ces domaines. Ce retard pourrait être mis sur le compte de choix technologiques qui diffèrent de ceux utilisés sur le X-37B. On suppose que le système de propulsion et que les matériaux de la protection thermique répondent à des exigences aérodynamiques et de vitesses différentes de celles de l'X-37B car l'avion chinois pourrait décoller comme un avion s'il n'est pas aéroporté.
Il est tout de même raisonnable de penser que ces progrès sont plus avancés que ce que pensent les services de renseignement occidentaux. Le dernier exemple en date est révélateur de la montée en puissance de la Chine : elle a fait voler son avion furtif bien plus tôt que ce qu'avaient prévu certains experts. Ce vol de bombardier biréacteur a été réalisé lors de la visite en début d'année du secrétaire américain à la Défense Robert Gates qui venait s’entretenir avec le président chinois Hu Jintao au sujet de la coopération militaire entre les deux grandes puissances. Voici l'avion en question : - Spoiler:
Connu sous le nom de Shen Long, cet avion spatial chinois, que l'on voit ici installé sous le fuselage de son avion porteur, met en œuvre des technologies qui pourraient servir à des vols spatiaux mais aussi pour d'autres utilisations. La Chine planche en effet sur des avions capables de voler à plus de Mach 10, susceptibles de relier n'importe quels points du globe en quelques heures. © DR

China Developing Counterspace Weapons: DoD Deputy
WASHINGTON - China is developing counterspace weapons that could shoot down satellites or jam signals, a Pentagon official said Feb. 4 as the United States unveiled a 10-year strategy for security in space.
"The investment China is putting into counterspace capabilities is a matter of concern to us," Deputy Secretary of Defense for Space Policy Gregory Schulte told reporters as the defense and intelligence communities released their 10-year National Security Space Strategy (NSSS). The NSSS marks a huge shift from past practice, outlining a 10-year path for the United States to take in space to ensure it becomes "more resilient" and can defend its assets in a dramatically more crowded, competitive and challenging environment, Schulte said. A key reason for developing the new strategy was "concern about the number of counterspace capabilities that are being developed," said Schulte. "China is at the forefront of the development of those capabilities," he said. China in 2007 shot down one of its own weather satellites using a medium-range ground missile, sparking international concern not only about how China weaponizing space, but also about the debris from the satellite that is still floating around in space. Beijing is also working on ways to jam satellite signals and is developing directed energy weapons, which emit energy towards a target without firing a projectile, Schulte said. U.S. concerns over China's space activities have led Defense Secretary Robert Gates to seek to include space in the stability dialogue with the Chinese, Schulte said. defensenews | |

New missile 'ready by 2015'
Soldiers on [color:537e=#000]Chinese missile frigate "Zhoushan" wave to see off China's sixth naval escort flotilla in the Gulf of Aden November 24, 2010. China's seventh naval escort flotilla began its escort mission on Wednesday. Photo:Xinhua By Zhang Han and Huang Jingjing The Chinese army is researching a new type of conventional missile that is set to be weaponized and entered into active service within five years, military sources have revealed. China Aerospace Science and Industry Corporation (CASIC), the nation's largest missile weaponry manufacturer, is set "to complete research, production and delivery of this new generation of missile by 2015," the China News Service reported Thursday. The new missile would be part of a network forming a solid defense system allowing for total coverage in both defense and attack, and capable of dealing with various threats from land, sea, air, space as well as cybernetic attacks, according to the report. The report, however, did not provide any further details of the new missile. A military source close to the development, speaking on condition of anonymity, confirmed to the Global Times yesterday that "The subject under development is a medium- and long-range conventional missile with a traveling distance of as far as 4,000 kilometers." "The research is going smoothly, and the missile will be produced and ready for service in five years," he said, noting that the project would also entail a three-year evaluation period. "It extends the range of China's missiles and will therefore greatly enhance the national defense capabilities," the source said. The source also unveiled that "the Chinese-made Dong Feng 21D missile, with firing range between 1800 and 2800 kilometers, is already deployed in the army." Foreign media have also speculated that the Dong Feng 21D is a "carrier killer" and would prove to be a game-changer in the Asian security environment, where US Navy aircraft carrier battle groups have ruled the waves since the end of World War II, the AP reported. China debuted its first stealth fighter jet, the J-20, in January, in a test flight that coincided with a visit to Beijing by US Defense Secretary Robert Gates. Following the successful test flight, speculations and assessments of Beijing's military advancement echoed around the world. The Pentagon this week formally rolled out a record base budget for fiscal year 2012 of $553 billion, up $22 billion from the level enacted for 2010. However, additional overseas war funding is down by $41.5 billion. This led Gates to counter-attack, warning Congress on Wednesday against making deeper spending cuts than those already proposed, telling lawmakers that the US faces threats ranging from militants to states "developing new capabilities that target our traditional strengths," citing Iran, North Korea, as well as China, Reuters reported. Li Daguang, a military expert at the People's Liberation Army National Defense University, told the Global Times that Thursday's revelation speaks volumes about the significant progress China had made in the field of missile technology as well as proving the country's commitments to transparency in military affairs. "But the real combat capabilities of the missile in complicated situations remains to be tested. There is still a huge gap between China and Western countries with regard to advanced weaponry development," he said, adding that China should always remain prudent and rational when presenting its military progress. Wang Yanan, an associate editor-in-chief at Aerospace Knowledge magazine, told the Global Times that some seem to favor wild speculation where the Chinese military is concerned. "US wariness doesn't suggest its inability to develop advanced missiles. The US is still a leader in this aspect as it possesses the most cutting-edge missile technologies," Wang said. globaltimes | |

- China's defense budget to grow 12.7 pct in 2011: spokesman
BEIJING, March 4 (Xinhua) -- China said Friday it plans to raise its defense budget by 12.7 percent to 601 billion yuan (91.5 billion U.S. dollars) in 2011, compared with an increase of 7.5 percent last year. The year's draft defense budget was 67.6 billion yuan more than 2010, and accounted for about 6 percent of the country's total budget, said Li Zhaoxing, spokesman for the annual session of China's national legislature. "The government has always tried to limit military spending and it has set the defense spending at a reasonable level to ensure the balance between national defense and economic development," said Li. The former foreign minister said China's defense expenditure is transparent and defensive in nature. "There is no such thing as a so-called hidden military expenditure in China, and the budget is subject to auditing from the government and military," he said. The bulk of the spending goes towards moderately improving armament, military training, human resource development, infrastructure of grassroots units and the living standards of the servicemen, said Li. China's defense budget is almost evenly divided in three parts -- the living expenditure of the servicemen, expenses for training and maintenance, and spending on equipment, said Major General Luo Yuan, a researcher with the Chinese People's Liberation Army (PLA) Military Science Academy. xinhuanet | |

- AFP: China 'hacked' into secret S. Korea military files
Chinese computer hackers last June gained access to secret South Korean military files on a planned spy plane purchase from the United States, a Seoul lawmaker says, as quoted by AFP. The hackers accessed information in defence ministry computers on the plan to buy unmanned Global Hawk aircraft, said Shin Hak-Yong, an opposition Democratic Party lawmaker and a member of parliament's defence committee. "A government official reported the incident to me... the government has not raised the issue with China yet and is still debating how to handle it," Shin's spokeswoman quoted him as saying, confirming his comments reported in Monday's Chosun Ilbo newspaper. Seoul last year earmarked 45.2 billion won (40.4 million dollars) for the spy plane purchase following the North's alleged attack on a South Korean warship that left 46 sailors dead in March 2010. Cross-border tensions escalated further after Pyongyang's shelling attack on a frontier island that killed four South Koreans including two civilians in November. The aircraft are capable of monitoring up to 200 kilometres (125 miles) north of the inter-Korean border. Japan is also considering buying the unmanned spy plane, Chosun said, unnerving China which fears the neighbouring nations could keep watch over its own territory. Ruling Grand National Party lawmaker Lee Sung-Hun, citing a government report, said 8,183 of 21,899 attempts last year to hack into South Korean government computer systems were made from China.

Oupss désolé, je viens de voir la question Je crois pas qu'il y a des données disponible pour répondre clairement à cette question, mais il est clair que les chinois font d'énorme pas dans ce domaine ... Ils préparent notamment un nouveau concept de SM sans hélices d'après ce que j'ai lu quelques part il y a quelques jours ... Sinon, le futur chasseur embarqué de la marine chinoise, a commencé ses essais ... développé sans l'aide des russes ( mais bon c'est leur concept de toute façon ), le J15 est la version embarquée du J9 alias SU27/30 _________________ | |

- China aims new missile at Taiwan: intelligence chief
File image. | by Staff Writers Taipei (AFP) March 16, 2011 Taiwan's top intelligence chief said Wednesday that China is targeting the island with a new type of ballistic missile. "The Chinese communists have deployed the Dongfeng 16, which is a new powerful missile aimed at Taiwan," said Tsai Teh-sheng, the director-general of the National Security Bureau. "Its range is longer, and it increases the threat to Taiwan," Tsai said while replying to queries raised by Lin Yu-fang, a legislator from the ruling Kuomintang party. Tsai declined to provide technical details about the new weapon as well as the number that has been deployed so far. Dongfeng means "East Wind". Taiwanese experts estimate China's People's Liberation Army currently has more than 1,600 missiles aimed at the island, mostly deployed in Fujian and Jiangxi provinces in the mainland's southeast. Tensions across the Taiwan Straits have eased since Ma Ying-jeou of the China-friendly Kuomintang came to power in 2008 on a platform of beefing up trade links and allowing in more Chinese tourists. However, China still refuses to renounce the possible use of force against the island to bring about its long-stated goal of re-taking Taiwan, which has ruled itself since the end of a civil war in 1949. The Pentagon said in an annual report to Congress last year that China's military build-up against Taiwan has "continued unabated" despite improving political relations.

China tests missile air defence system K J M Varma Beijing, Mar 29 (PTI)
Chinese military has conducted a drill to test its integrated air defence capability under the scenario of a massive air strike.
The tests which were held last week were aimed at bringing compatibility among various kinds of missile systems built by China, official media reports here said. The tests included surface-to-air missiles, also known as SAM.
Over the years China has built an intact missile defence network consisting of various kinds of missile systems.
New missile systems delivered to the regiment in recent years were not compatible with older models, commander of the missile regiment Wan Dexin said without disclosing the location.
"They have different ports, formats and protocols," Wan said.
Integrating different missile systems has enhanced the combat capability of the whole regiment, Wan said.
"Chinese air defence technology is advanced, but needs to improve in order to match the capabilities of the US," Zhang Qihuai, a professor with the Logistics College of China Air Force, told state-run Global Times.
Zhang said the Chinese missile industry has provided the People''s Liberation Army (PLA) with a series of modern air defence systems.
However, the majority of the SAM systems deployed in China, namely the HQ2, are domestic variants of the Soviet C75 (NATO code name SAM2), which became operational in 1957.
The situation has been gradually improving after 1990, when the Russian S300 longrange SAM system was delivered, he said.
In another development, China recently allowed more military family members to join loved ones serving in the army, which would help nearly 100,000 servicemen to end the separation from their spouses.
This new policy was approved by the Central Military Commission, PLA Daily reported.
The policy allowed lower-ranking military officers, such as company commanders to live with their family members during their time in the army, while the previous regulation permitted vice battalion commanders or above.
The policy also offers more conveniences for military families with servicemen in difficult and remote regions and in special posts, such as those serving at missile and satellite test bases, to now live together, it said.

Chinese Navy Develops Combat Capability
The Chinese Navy has developed its combat capabilities in distant waters, countering non-traditional security threats, a white paper on the country's national defence has said. The white paper also reported that the navy had intensified the modernisation of its integrated combat forces and enhanced its capabilities in strategic deterrence and counterattack. "It seeks to further improve its combat capabilities through regularised and systematic basic training and actual combat training in complex electromagnetic environments," the white paper added. China has been participating in joint drills to develop training models for military-operations-other-than-war missions (MOOTW), according to Xinhua News Agency. According to the white paper, the navy has deployed new types of submarines, frigates, aircraft and large support vessels as planned naval-technology | |
