The Chinese army conducted a large-scale military exercise on the landing of amphibious assaults on the coast of one of the islands, apparently, the landing on Taiwan is being practiced during the exercises. On the video, you can see the entire cycle of the landing operation, from the destruction of coastal fortifications by floating self-propelled artillery installations to the landing and capture of the island.

These Chinese are always up to something corny! After the farce of their drones trying to drop food packets to their troops in Ladakh, here's another silly invention of theirs for their planned deployment in Ladakh!!

The service ceiling of these toys is 4000m while the average altitude of Ladakh is 4400m!! Lol. Nuff said!!

China Develops ‘Anti-Stealth Radar’ So Small That It Could Be Set Up Anywhere, Including Rooftops – Scientists

Scientists from China’s Xidian University claim to have developed an anti-stealth radar so small that it could be easily set up anywhere, including on a rooftop, as per a report by Chinese media.


Usually, anti-stealth radars need a large antenna to pick up the weak signature of a stealth aircraft that can absorb or deflect waves emitted by a radar, compromising the mobility of the radar and making it vulnerable to attacks.


“Although the detection accuracy of the radar can be improved by increasing the antenna aperture, it will reduce the mobility and survivability of the radar platform,” said professor Yang Minglei of the national laboratory of radar signal processing at Xidian University in a paper published in the domestic peer-reviewed journal Modern Radar on August 11.


Yang and his team developed a metric wave radar that is similar in size and looks like a clothes-drying rack, reported SCMP. The researchers claim that the device is mobile and demonstrated superior performance in terms of accuracy in detection during several tests carried out on the roof of a university campus building.

Research on anti-stealth radar technologies was picked up by China, particularly after an American B2 stealth bomber accidentally attacked the Chinese embassy in Belgrade during NATO’s 1999 air war over Yugoslavia. The alliance struck several targets in Serbia and Kosovo.


Currently, China has a multi-layered air defense system with anti-stealth radar stations, particularly along the eastern Pacific Ocean and the South China Sea coastline.


For example, a very high frequency (VHF) radar array is located on the Subi Reef, which Chinese media describes as a ‘counter-stealth radar.’ Subi Reef is a Chinese-held reef in disputed Spratly islands, also claimed by Vietnam and Taiwan.


China has a military outpost on this reef, with the VHF radar array, described by Chinese scientists as a synthetic impulse, and aperture radar (SIAR) located on the southern end of the outpost as of 2020.


The radar operates within the frequency band of 30-300 megahertz and consists of three concentric rings of antenna elements.

According to Chinese researchers, using circular, random height antenna configuration and SIAR signalprocessing techniques enables the radar to overcome the usually accepted limitation of VHF-band radar and operate as a genuinely four-dimensional radar that can determine the range, azimuth, elevation, and velocity of airborne targets.


Furthermore, the radar is also said to be capable of detecting and tracking low-flying targets due to its ability to overcome ground clutter.


Apart from that, there is also a High Frequency (HF) radar on the Cuarteron Reef, part of the disputed Spratly islands, held by China and claimed by the Philippines, Vietnam, and Taiwan.

The HF radar on the Cuarteron Reef consists of evenly spaced 20-meter poles and can reportedly detect objects, including stealth aircraft, at up to 3,000 kilometers.


However, as EurAsian Times has reported earlier, the HF radars can detect stealth planes, but they lack the precision to guide a weapon toward the target. The HF radars cannot accurately determine an airborne target’s range, altitude, and precise direction.


The radar resolution cells of an HF radar can be several miles apart, meaning the radar can only signal the other sensors to search the airspace or guide fighters toward a roughly defined search area.

Metric-Wave Anti-Stealth Radars

As stated above, the latest anti-stealth radar developed by professor Yang Minglei and his team is a metric wave radar. These types of radar are usually huge, with even the mobile versions being tens of meters high when extended, requiring large trucks to be towed and can take hours to set up.


Also, their huge size makes them easily detectable by satellites and vulnerable to attacks. For example, the JY-27 radar, manufactured by China Electronics Technology Group (CETC), was destroyed by an Israeli airstrike in 2019.

The JY-27 radar in question was a part of the Syrian Air Defense at Damascus airport and was allegedly destroyed by an F-35i Adir fighter jet of the Israeli Air Force on January 20, 2019, indicating the ability of the radar to detect a stealth aircraft is also questionable.


Nevertheless, the incident led to concerns about the survivability of these anti-stealth platforms.


The metric-wave radar system developed by Yang and his colleagues consists of two identical antennas separated by about 20 meters on the same rooftop.

The antennas are connected by an optical cable to work simultaneously, with one emitting low-frequency electromagnetic pulses and the other detecting the returning signals.


The researchers claim that the dual antenna array provides extensive area coverage, allowing the system to pick up more long waves reflected by a target.


At the same time, however, the gap between the antennas also created extra noise or false signals, potentially affecting the accuracy. The researchers claimed to have developed an algorithm that could extract valuable signals from strong background noise by analyzing data collected by antennas in different locations.


Yang’s team said that the data flow generated by the new radar system was greater than usual, which needed four domestically produced Hunxin 1 chips for processing.


The Hunxin 1 is a coin-sized processor made using 55-nanometer technology. It has been used widely in Chinese cars, machinery, and military equipment for nearly a decade because of its low cost, high performance, and stability, even in harsh environments. The technology is so old that it will remain unaffected by US sanctions, reported the SCMP.


“The chip has a quad-core parallel processing structure with powerful floating-point computing capabilities, which can very well meet the application requirements of high-speed real-time signal processing,” Yang noted in the paper.


That said, the actual efficacy of the new radar in detecting real-world stealth aircraft like an American F-35 and F-22 remains unclear. Yang’s team said in the paper that the radar was used for tracking civilian aircraft, and the test data suggested the technology worked.

Defence economics of China. Some takeaways for India:
  • Deng reduced soldier numbers in order to funded army modernisation (Agniveer following in those footsteps?)
  • Defence spending grown in proportion with x10 economic growth since 2000s
  • Budget is effectively larger than advertised, possibly twice as large
  • PPP effect further closes the gap to USA defence spending (though still nowhere close to USA capability)
  • Industrialisation matters! No industry/manufacturing no MIC (slow progress of SU-57 development compared to J-20 attributed to comparative shrinking of Russian economy)
  • Heavy defence R&D spending - more than USA in percentage terms but still having to import certain high tech, mainly from Russia (not to mention "absorption of foreign tech")
  • Despite higher wages, Russia, South Korea, Ukraine reduce PPP disadvantage by having mandatory conscription (India buying from high wage countries France and USA is not sustainable - must internalise)
  • Civilian and military sectors complement each other (does Indian MIC also make civilian wares to sell for profit?)
  • Massive naval buildup (made possible by scale of steel making industry) - must plan for heavy PLAN presence in IOR

China Dreams to be a superpower some day, to achieve this goal it has already begun its journey.

Ever Growing Submarine Force of China :
Admiral Zhang led Chinese Navy’s submarine modernization program and oversaw the acquisition of four modern Russian-built KILO subs, including the stealthy Type-636. Orders for eight more are on the books, with the first new boats to be delivered soon. Russian shipyards are at work to fill China’s orders for new submarines.

Admiral Zhang isn’t relying solely on the Russians. He has also increased production—to 2.5 boats per year—of China’s new, formidable Song-class diesel-electric submarine. China is also testing a new diesel-electric that the defense intelligence community has designated the “Yuan.” The Yuan is heavily inspired by Russian designs, including anechoic tile coatings and a super-quiet seven-blade screw. The addition of “air-independent propulsion,” which permits a submarine to operate underwater for up to 30 days on battery power, will make the Song and Yuan submarines virtually inaudible to existing U.S. surveillance networks—and even to U.S. subs.

These new submarines will be more lethal when armed with Russian SKVAL (“Squall”) torpedoes, which can reach 200 knots. There are reports that the SKVAL is already operational on some Chinese subs. As well, Russia has also transferred the Novator 3M-54E three-stage anti-ship cruise missile to China’s submarine fleet for use against aircraft carriers. Each Chinese KILO is armed with four of these missiles.

America’s Endangered Submarine Supremacy
In February 2005, Secretary of Defense Donald Rumsfeld commented that the size of the Chinese fleet could surpass the United States Navy’s within a decade. “It is an issue that the department thinks about and is concerned about and is attentive to.” Indeed, the U.S. Navy will hold a series of major naval exercises in the Pacific this summer that will involve four aircraft carrier battle groups, including a carrier normally based on the U.S. East Coast. This will be the first time the Navy has deployed an Atlantic Fleet carrier to a Pacific exercise since the Vietnam War.

However, there is little indication that the Pentagon is taking the Chinese submarine challenge seriously. If it were, the Quadrennial Defense Review (QDR) issued earlier this month would have recommended that the erosion of the U.S. submarine fleet come to an end.

But the QDR envisions a “return to a steady-state production rate of two attack submarines per year not later than 2012 while achieving an average per-hull procurement cost objective of $2.0 billion.” This means that the U.S. sub fleet will continue to decline for another six years, during which time America’s industrial base for constructing subs will further diminish and the per-unit cost of submarines will jump past $2 billion, impelling further cuts in the fleet.

Of the U.S. Pacific Fleet’s 35 submarines (including three nuclear attack submarines based in Guam during 2006), about a dozen are underway at sea on operational duties at any one time. Under the QDR’s most optimistic estimates, Pacific Command’s sub fleet will diminish to about 30 by 2025.

Electric Boat (EB), the nation’s preeminent submarine contractor, has announced plans to lay off 900 of its 1,700 designers and marine draftsmen engineers over the next three years. This is a crisis. It will mark the first time in 50 years that the U.S. has not had a new submarine design on the drawing board. EB laid off nearly 200 submarine engineers and machinists in early February—and EB is the only shipbuilder in the nation that maintains submarine designers. As the build-rate for subs collapsed, EB used maintenance and repair work to pay designers’ salaries and maintain its staff of highly-skilled steelworkers. But without new orders, EB will lay off almost half of its workforce of over 5,000 over the next three years

U.S. Navy combatant commanders already require 150 percent of the attack submarine days currently available, and these requirements will only increase as the submarine force dwindles. If the United States allows production to dwindle further, expertise will be lost and costs will skyrocket for any new classes of submarines contemplated for the post-2012 period.

Meanwhile, China’s fleet of modern attack submarines is growing: China already has ten Song/Yuan/Kilo submarines in the Pacific today, over 50 older Ming-class and Romeo boats, five Han class nuclear attack submarines, and one Xia-class ballistic missile submarine. In addition, China has 25 new boats under contract now; 16 are under construction today, including a new class of nuclear attack submarine designated the Type-093 and a new nuclear ballistic missile sub, the Type-094.

The U.S. has three submarines under construction today. Although the Navy’s new 30-year shipbuilding plan calls for 48 nuclear attack submarines in the fleet by 2035, the Navy’s top submarine commander, Vice Admiral Charles L. Munns, has testified before Congress that the Navy needs at least 54 boats to fulfill current critical missions. This number will rise as China’s navy expands.

If the Navy does not start launching new subs at the rate of two per year until several years after 2012, the force would dip to a low of 40 in 2028, or 17 percent below the Navy’s stated needs. And that rate will not even permit the Navy to reach its sub-minimal target of 48 attack submarines until 2034. All of this assumes that the Navy does not decommission ships faster than expected due to expanded operations in coming years.

China’s Intent
The QDR addresses the question of China’s intent:

Chinese military modernization has accelerated since the mid-to-late 1990s in response to central leadership demands to develop military options against Taiwan scenarios. The pace and scope of China’s military build-up already puts regional military balances at risk. China is likely to continue making large investments in high-end, asymmetric military capabilities, emphasizing electronic and cyber-warfare; counter-space operations; ballistic and cruise missiles; advanced integrated air defense systems; next generation torpedoes; advanced submarines; strategic nuclear strike from modern, sophisticated land and sea-based systems; and theater unmanned aerial vehicles…

According to the MPPRC Report’s executive summary, China’s specific intent is to “build counters to third-party, including potential U.S., intervention in [Taiwan] Strait crises.” The report continues, “Deterring, defeating, or delaying foreign intervention ahead of Taiwan’s capitulation is integral to Beijing’s strategy.” To this end, China is expanding its “force of ballistic missiles (long-range and short-range), cruise missiles, submarines, advanced aircraft, and other modern systems.”

China’s Sea-Power Goals
If they are curious about China’s intent, Pentagon planners might look to comments by General Wen Zongren, Political Commissar of the Chinese People’s Liberation Army’s elite Academy of Military Science. The MPPRC Report quotes General Wen as asserting that China must “break” the “blockade [by] international forces against China’s maritime security… Only when we break this blockade shall we be able to talk about China’s rise… To rise suddenly, China must pass through oceans and go out of the oceans in its future development.” In fact, it is the explicit goal of the Chinese Communist Party to “increase the comprehensive strength of the nation.”

The Chinese navy—and its submarine fleet, in particular—is a key tool in achieving that goal. The September 2004 promotion of Admiral Zhang Dingfa, a career submariner, to Chief of Staff of the People’s Liberation Army Navy (PLAN) and a full seat on the Central Military Commission was a clear signal of the primacy of submarine warfare in China’s strategy for the Asia-Pacific region.

It is believed By 2025, China’s navy could rule the waves of the Pacific. By some estimates, Chinese attack submarines will outnumber U.S. submarines in the Pacific by five to one and Chinese nuclear ballistic missile submarines will prowl America’s Western littoral, each closely tailed by two U.S. attack submarines that have better things to do. The United States, meanwhile, will likely struggle to build enough submarines to meet this challenge.


Recommendations :
Just Imagining China Challenging The United States soon somewhere in a decade or two & the implications it will have on INDIA ( Pak being its close ally) to counter this threat INDIA must build at least two, new attack submarines per year.

A more Potent & effective Anti-Submarine Warfare & Surveillance System needs to be developed with immediate effect.

We also need Strategic Partners & Help ourselves along with them to Boost Fleets - Japan, Taiwan & South Korea can Play a Pivotal role.

Remember Gentlemen, we are heading towards another World War, with the Chinese Pace Gaining momentum the ultimate war is not too long.
After they lost the Taiwan propaganda war over Nancy Pelosi visit, Chinese stature as naval or air power has been downgraded. Any amount of propaganda all written by Chinese will never cut ice. On top of that reduced economic activities due to Covid shutdown and lack of rain (drought) has brought economic activity in China to 2% growth this year.

My point here is that Chinese power propaganda is still strong but it is not cutting any ice.
