What's new

China Space Military:Recon, Satcom, Navi, ASAT/BMD, Orbital Vehicle, SLV, etc.

But I have recently heard multiple reports of many Chinese convicted in US for trying to export radiation hardened chips to China. Why would China need to import them, if it makes them?
As you are probably aware, US has maintained an arms embargo on China since 1990s. These chips are likely on the list and are commercially sought after items.

As to why someone need to import them, you have to ask the person that try to get it from US. Logically it would probably because they could make money by selling to people that could not get it.

Since almost all chips that are used in space, has to be radiation resistance/hardened if intended for prolong use, I would have expect the one export to Russia would be so.

Since the Russian are expert in space tech, I would expect those chips are up to mark to the Russian satisfaction, otherwise they would not have want it.

China might have been successful in making world-class space chip that are economically competitive, below is a relevant report from China Daily, take note of the last sentence.

China-made chips launched into space

With the 18th and 19th Beidou satellites, developed by Wuhan Optics Valley Bei Dou Holding Group Co., Ltd, launched into space late last month, China's proprietary navigation system is one step closer to global coverage. For the first time, the satellites systematically used home-developed chips, said an industry insider.

According to a report from China News Service, 98 percent of the components - including all the essential parts and equipment - in the two satellites are home-designed. One of the core components for navigation, the rubidium atomic clock, replaced imported products for higher accuracy in positioning, range finding and timing services.

About 40 products, including the central processing unit, the data bus and the memory unit, were designed and made by the Beijing Microelectronics Research Institute, a subsidiary of China Aerospace Science and Technology Corp.

Led by Zhao Yuanfu, the institute is responsible for the development of aerospace-use chips. It was founded in 1994 and its first chip was launched into space in 2003.

The institute has always focused on the independent development of new-generation aerospace-use CPUs, rather than imitating overseas products.

"Even if we could successfully copy others' designs, they will have developed new products by then," Zhao told People's Daily. "Imitation leads to no competitiveness.

"We cannot depend on others for our core technologies. We see those technologies as our fundamental capabilities."

He said that information security is a matter of national strategy, and home-developed chips will provide hardware support. He added that China currently spends more than $200 billion on importing chips.

"Only by developing an independent and complete product portfolio can we have reliable operation of satellites," said Zhao.

He said that the chips used in the two recently launched satellites have world-class performance, and are more advanced than overseas products in terms of radiation resistance. He explained that satellite chips must be specially treated to resist strong radiation because of the complex environment in space.

Traditionally, satellite chips are processed on special production lines to acquire radiation resisting abilities, but Zhao had an innovative idea that allows the chips to acquire the ability via a special design, so they can be manufactured on ordinary civil-use integrated circuit production lines to reduce manufacturing costs.

The CPU he helped develop features a high processing speed and multiple interfaces to cater to the different functions of various satellite modules.

"A good home-developed chip means not just the chip itself, but also an entire home-developed system that integrates chips and software," Zhao said.

Zhao's team have published more than 600 academic essays and have been granted more than 200 patents. They now also have orders from overseas.
 
That's just one way statement, we could discuss to know more on this, make clear the situation and find out the true performance of Great China equipments.

This is a great question, buddy. And a good goal to understand more of our chinese peers' defense abilities. :)

this would put virgin galactic future small satellite launch services out of business before it even started. their max payload 200kg to the lowest orbit and price almost the same. lol

The sighted object measured 22.5 metres by 13 metres, and was said to be 75 miles (120km) from possible debris sighted days earlier by Australian satellites.
 
China's Submarine Hunting Plane Has A Giant Stinger
The Y-8Q joins the mile-high sub-hunting club

Y-8Q in Color

The Chinese Naval Air Force gets its first operational Y-8Q heavy submarine hunting aircraft, after several years of flight testing. Painted in the standard PLANAF grey as opposed to the bright yellow primer seen on the pair of prototypes, the Y-8Q will likely show up all around East Asian waters after the Chinese flight crews learn how to fully exploit the limits of their new technology.

China is making serious efforts to correct its longstanding deficiency in aerial Anti-Submarine Warfare (ASW), introducing the Shaanxi Y-8Q (also designated as the Y-8GX6) aircraft painted in the blue-gray People's Liberation Army Navy Air Force (PLANAF) colors into operation. Previously, two Y-8Q prototypes had been flying for the past several years as part of a rigorous testing and training regimen. Until this month, China's only long-range aerial ASW capability came from three Harbin SH-5 seaplanes, which are nearly thirty years old.

The Y-8Q is designed to overcome Chinese ASW deficiencies that would cripple Chinese naval and civilian maritime activity in war. Some of its technology, at least on the surface, compares favorably to the U.S. P-3C Orion and P-8 Poseidon, and the Japanese P-1. The Y-8Q's most distinctive feature is its seven-meter-long Magnetic Anomaly Detector (MAD) boom, which detects the magnetic signature of enemy submarines' metal hulls as the Y-8Q flies over them. Since MAD performance correlates to size, and it's seven-meter MAD boom is arguably the largest of its kind among airplanes, the PLAN would have a fine weapon for hunting otherwise stealthy submarines.

Y-8Q MAD

The Y-8Q's MAD boom on its tail is possibly the largest one mounted on an aircraft. The MAD is located on a boom in order to minimize electromagnetic interference from the Y-8Q itself, as the MAD detects any magnetic signatures from the metallic hulls of submarines lurking beneath the waves.

The Y-8Q also has an electro-optical turret forward of its bomb bay, which has day, night and infrared cameras to hunt the heat signatures and wakes of small watercraft, unmanned vehicles, and submarines (especially snorkels and periscopes). Right under cockpit is a large radome that, in addition to detecting submarine periscopes and wakes, can provide targeting data via satellite link to Chinese aircraft and warships when the Y-8Q finds enemy warships. The Y-8Q can also drop a hundred sonobuoys to provide real time sonar coverage of seawater expanses.

This photo gives us a good view of the Y-8Q's sensors, including the electro-optical turret (the white sphere forward of the bomb bays, similar in size and function to the one found on the Reaper drone), and the gray radome under the cockpit.

SQ-5 Sonobuoys

Chinese Military Aviation

The Y-8Q can carry at least a hundred sonobuoys to provide blanket sensor coverage over a patch of ocean the size of Rhode Island. Other Chinese ASW platforms, like the Z-18 helicopter, also carry these sonobuoys.

The exact weapons capacity of the plane's internal bomb bay is not yet public, but one estimate is that the Y-8Q can carry probably over 10 tons. (By comparison, the Y-8 transport carries 20 tons of cargo.) Likely weapons loadouts include torpedoes like the Yu-7, sea mines and anti-ship missiles. The Y-8Q's large size and sensors could also allow it to be a command center for underwater unmanned vehicles (UUVs) like the Haiyan glider that would guard sectors of the ocean floor while the Y-8Q flies off elsewhere.

Haiyan UUV

China News

The Haiyan UUV is an underwater glider, which can dive under 1,500m below the ocean surface, for up to 30 days. These 70kg drones (or future militarized versions) could be deployed enmass by Y-8Qs to provide a quick but long-term sensor solution, in areas like the Taiwan Straits, against enemy submarines during war time.

Since the Y-8Q is extending Anti-Access/Area Denial operations underwater, it is almost a given that China is going to invest in future ASW methods. In the future, the Y-8Q may be equipped with more exotic technologies like LIDAR (which uses laser beams to penetrate water to detect objects), hard kill anti-torpedo systems, acoustic signals intelligence and radiation detection (identify radiation from nuclear reactors) that Chinese scientists are already beginning to research.

ASW Attack Missile

Navy Recognition

This long range anti-submarine rocket is a proposal by Poly Technologies, a Chinese industrial conglomerate, that was first unveiled in September 2014 at a South African arms show. The ASW rocket uses a heavy WS series artillery rocket to fire a light torpedo (possibly a 500kg Yu-7) over 100 km away at enemy submarines that have been detected by a sensor network. A Y-8Q could act as a command center for Chinese UUVs and long range anti-submarine rockets to effectively deny large areas of water to enemy submarines without placing Chinese submarines or warships in danger.

The Y-8Q will become a significant part of China's emerging ASW operations. Its 5,000km range, wide sensor and weapon range and massive payload will exponentially increase Chinese security against enemy submarines off its coasts and into the East and South China Seas. When combined with other ASW assets, such as underwater drones, missile launched torpedoes and sonar towing Type 056 corvettes, it could make current and planned regional investment into submarines by China's neighbors more of a risky proposition.
 
@cnleio : did they launch missile to the target with Red Cross symbol in White background during test flight?

Thanks for distribute to the thread, but could you make a favor to focus on the tracking ability than any attack activity? Thanks

A report by Feng
As a whole, the hardware for ASW in PLAN has definitely modernized, but they still lack in many areas. While they finally have a Y-8 maritime patrol aircraft, it's still years behind P-3C and serving too small in number. While Z-18F is a nice addition, a Z-20 or Z-15 based ASW helicopter is badly needed for ships in the class of Type 052D and 054A. And finally, the biggest help to Chinese navy would be newer and quieter nuclear submarines with more powerful sonar. Until that happens, the Chinese navy would always be in a place of danger when it comes to underwater warfare.
