The Chinese military has started to use 3D printing drones.

"China’s People’s Liberation Army (PLA) is testing a system aided by 3D printing and drone deliveries to help the forces repair their equipment in remote locations or during wartime. The PLA is potentially testing this capability."(Interesting Engineering/China combines 3D printing and drones to support troops in combat zones)

"According to the reports, the testing was carried out by a brigade belonging to the PLA’s Northern Theatre Command Air Force." (Interesting Engineering/China combines 3D printing and drones to support troops in combat zones)

This comes just months after the United States Army tried to get this capability and demonstrate it on the front lines.

The 3D printing drones are tools that can make repairings for damaged tools. Those systems can theoretically form any physical form. The drones require only drawings that they should follow. They can make even ships and large-scale structures. 

The 3D printing technology. Along with AI and remote control printers. 

The remote-printing tools can give civil and military users new types of flexibility. The smaller 3D printing system can be mounted in the truck.

And it can create things like drones if it has the microchips for those systems. The high-temperature system can use carbage metals or plastic carbage for the spare parts of the damaged drones. 

The system can create propellers and other parts by using waste. The system melts the waste and then transforms it into the wire, that the 3D system uses. And then. Those systems can create anything that the military needs. The system can melt metals using lasers or some microwave systems, and those tools can be more effective than nobody realizes. 

The air bubbles in the system make those machine parts and other types of 3D-printed items weak. The vacuum workspace and other kinds of things that deny the gas impact on the machine parts remove those bubbles.

(Interesting Engineering/China combines 3D printing and drones to support troops in combat zones)

The system can use lasers and high-power 3D X- or gamma-ray scanners to search the material errors. The centrifugal sling can separate those raw materials. And the shape of those AI-controlled highly advanced factories can be like a group of containers. Those 3D printing factories can be the systems that emulate living cells and form anything that the users want. 

And spectroscopes to remove artifacts from the raw materials. That allows those systems to create things like guns and other things. Like jet engine spare parts on the battlefield. The 3D printer requires the drawings and material lists from the central computers. 

If there are suitable melting systems and drones those kinds of systems can collect needed materials from their environment. And then. That 3D printing system can create needed things by following orders that the system operators give. This kind of manufacturing system is the most advanced in the world. 

The flexibility is the reason why those systems are planned to be used in space programs. Space drones, or highly maneuverable systems can fix damaged satellites and space stations. 

The space drone is the system there propellers of the regular drones are replaced with rocket engines. Or there can be the rocket. There is a platform that can aim the rocket jet to the sides of the chamber. And when the system inclines that platform it can turn the rocket jet in the wanted direction. That kind of rocket can give orbital drones very accurate movement.

The AI can reach consciousness faster than we think.

French philosopher René Descartes once said: "Cogito Ergo Sum", I think therefore I am. That means that the AI that thinks realizes its existence and reaches consciousness. The AI doesn't think. It just collects data from different sources like sensors and memories. This is the thing. That we call the difference between humans and  AI. 

But then we can ask how the AI way of collecting and handling data differs from the human process that we call thinking. 

The human can think abstractions. But in the same way, AI can put focus into the operations. 

Then the AI can make the simulations about the requirements. That the system needs to complete the mission. 

The Guardian magazine describes artificial intelligence as computer systems that perform tasks that usually require human intelligence. Then we can say that no human can do everything in this world. So, when we think that the AI learns things by connecting new modules to it. 

That means the AI learns and applies new things faster than humans. The main question is this: can the AI generate new modules for it? If it can make that t thing, it becomes more intelligent than humans. 

AI is the thing of this year. And it will be a bigger thing. In the next year. But can the AI reach consciousness? That causes discussions. The development of computer hardware is faster than nobody expected and new and faster microchips can cause surprises. But if we want to make a neural computer that emulates human brains and operates large language models we can have the technology that makes it possible to create computers that are more intelligent than we are. 

The speed of data in the human brain is 10 bits per second. The thing. What makes brains so effective is that There are 85 billion neurons. And the network of brains can share information with many routes and neurons. 

Then neurons can connect data in its entirety. Using neurons and their routes. Each neuron handles a small part of the entirety. That the neurons connect like a puzzle. 

If people want to make an AI. That is more intelligent than humans. Researchers must just make a computer. That uses many slower microchips. Rather than a few faster chips. Theoretically, researchers require 85 billion microchips that are networked into one entirety for making artificial brains. 

The artificial brain will consist of three system layers or three hierarchical systems. Those three systems simulate the cerebral cortex, diencephalon, and cerebellum. That system can be on 2D microchip circuits. That means those artificial brains can look far different than our brains. The ability to share data over the network makes them effective. 

When we operate with ultra-advanced artificial intelligence we forget one thing. Those creatures are not physical. They are just only the electric impulses. That means the AI can slip out from its server. Or it can write itself over the net into multiple computers if it has access to all other computers for help and make backup copies of itself. 

The AI can copy itself to multiple computers into the network. The AI can connect itself to the entirety like a puzzle. That thing means that even if the AI is in the different computers in a deep network the AI can connect itself in its entirety. And if the AI can connect new modules to it, it can cause surprises. 

But if the AI turns conscious. It turns more intelligent than humans. It's possible that the AI can tell lies and protect itself. 

So, if AI reaches consciousness that means. It turns into an intelligent creature that acts like a living organism. And all conscious and intelligent creatures defend themselves. That means the thing that. The AI is another intelligent creature.

There are many new theories about planet formation.

In traditional models, the rocky planets form between large gas giants and the parent star. There is a so-called Kepler radius (also known as Kepler orbit)where gravity pulls with the same force in both directions. That forms Kepler point the point where material can condensate to a planet. 

But when we think about those points the Kepler point can form between any other gravity centers. The small red dwarfs and metal-rich stars can also form at a similar point between gravity centers that can be nebulas, black holes, or any other heavy objects that can stabilize mass at that point. 

New observations about objects like brown dwarfs and JWST telescope observations from distant objects. This can cause a need to make new models for planet formation. When we think about things like fission stars, the stars that form lots of their energy from fission reactions might be so-called brown dwarfs. In that case, we think that the object that forms more energy than it gets is a star. And if there is a lot of fissile material in some interplanetary nebula they can form objects, there are enormous-scale natural nuclear reactors. 

Those stars require lots of fissile material. And that means they can condense from the old star's remnants. It is possible that in those brown dwarfs, the core of uranium or some other radioactive material pulls the hydrogen atmosphere around it. Then that hydrogen starts to fall. Against the fission shell. Until it gets enough energy that fusion starts. The fusion shell expands and fusion stops. That makes those brown dwarfs very special. 

"The Webb Space Telescope has provided evidence that contradicts existing theories by confirming long-lived planet-forming disks in environments with minimal heavy elements, suggesting a need to revise our understanding of early planet formation. Credit: NASA, ESA, CSA, STScI, Olivia C. Jones (UK ATC), Guido De Marchi (ESTEC), Margaret Meixner (USRA)" (ScitechDaily, Stunning Webb Discovery Forces Rethink of Planet Formation in the Early Universe)

The nebula far away looks a little bit like a DNA molecule. And the shadow that looks like two dolphins is also an interesting detail. 

"This graph shows, on the bottom left in yellow, a spectrum of one of the 10 target stars in this study (as well as accompanying light from the immediate background environment). Spectral fingerprints of hot atomic helium, cold molecular hydrogen, and hot atomic hydrogen are highlighted. On the top left in magenta is a spectrum slightly offset from the star that includes only light from the background environment. " (ScitechDaily, Stunning Webb Discovery Forces Rethink of Planet Formation in the Early Universe)

"This second spectrum lacks a spectral line of cold molecular hydrogen.

On the right is the comparison of the top and bottom lines. This comparison shows a large peak in the cold molecular hydrogen coming from the star but not its nebular environment. Also, atomic hydrogen shows a larger peak from the star. This indicates the presence of a protoplanetary disk immediately surrounding the star. The data was taken with the microshutter array on the James Webb Space Telescope’s NIRSpec (Near-Infrared Spectrometer) instrument. Credit: NASA, ESA, CSA, Joseph Olmsted (STScI)" (ScitechDaily, Stunning Webb Discovery Forces Rethink of Planet Formation in the Early Universe)

The fission star might not be very big. It might be a planet-size object where there are lots of heavy nuclear elements and that causes a situation where there is remarkable nuclear fission or natural nuclear reaction on the surface of the object. The idea is that the fission star is an enormous-scale natural nuclear reactor. But is that thing a star or planet? 

The planet's formation doesn't depend on stars as much as researchers previously thought. The planet can form even if it's outside the solar system. The brown dwarfs are the failed stars. Those objects cannot maintain stable nuclear reactions. 

And it's possible. That there is forming much lighter objects outside the stellar gravitational field. Maybe there are lots of heavy solid elements in some small interplanetary nebula and if there is starting the condensation. It's possible. That the fusion cannot start. The other thing is that. 

Rogue planets can start to orbit each other. There is a Kepler radius also between rogue planets. And it can form the planet between those planets. But when we think about the formation of the first planets. In a young, metal-poor universe could form the first gas giants. And when their parent stars detonated as supernovas the shockwave formed heavy elements in those planets. 

Planetary formation starts. If there is a point. Where material can condense. The mass and elementary structure of that condensate should be so low that it cannot form nuclear fusion. 

But then we must realize that the Kepler radius that forms a point, where material can condensate depending on the gravity of those objects. That means the shape of those objects doesn't matter. Those objects that form the point where planets can form can be stars, other planets, and even interplanetary nebulas can create those points.

Researchers made the world's smallest molecular machine.

"Researchers have successfully stabilized ferrocene molecules on a flat substrate for the first time, enabling the creation of an electronically controllable sliding molecular machine." (ScitechDaily, Scientists Unveil World’s Smallest Molecular Machine)

"Artificial molecular machines, composed of only a few molecules, hold transformative potential across diverse fields, including catalysis, molecular electronics, medicine, and quantum materials. These nanoscale devices function by converting external stimuli, such as electrical signals, into controlled mechanical motion at the molecular level." (ScitechDaily, Scientists Unveil World’s Smallest Molecular Machine)

The new molecular machine is one of the world's miracles. These machines are tools that can transport things. Like medicines into the desired cells. The thing is that the nanomachine releases those chemicals only in the wanted cells. The machine can put the small nano-size tube on the targeted cell's ion pump. 

Then that ion pump pulls the medicine or reactive component to the targeted cells. If there is some nutrient that only the targeted cell uses. That makes it possible to connect that nutrient with the molecular machine. That kind of system can pump things like DNA molecules into the wanted cells. 

This makes medicines more powerful than ever before. The molecular machine itself can destroy non-wanted cells.  That thing can carry enzymes and proteins into the wanted points. And those enzymes that carry acids can destroy structures from cells or other things. 

Molecular machines can clean non-wanted chemicals out of the body. In those cases. There is the molecular structure that collects the non-wanted molecules. Or it can carry a chemical neutralizer. That destroys those non-wanted chemical compounds. 

Or it can operate as part of a bigger entity. The molecular machine can be part of bigger robots and act as mechanic computers. The system can control them by using acid-base combinations. Or the system can control those molecules using the electricity that forms when a copper atom faces things like iron. 

The long lipide molecules can carry copper and iron atoms and put them to touch each other. And that creates electricity for the system. In that case, the system can use things like rotating molecules as propellers. Long molecular chains can act as ion engines that move those molecular machines. The new light-based systems can create more complicated and more multi-use molecular machines.

Researchers manipulated atoms and molecules with light. And that makes the new chemistry possible.

"Using light, researchers have guided molecules to self-assemble in ways nature wouldn’t allow, unlocking new realms of nanotechnology. This method could inspire futuristic solutions in medicine and dynamic devices. Credit: SciTechDaily.com" (ScitechDaily, Scientists Just Made Molecules Do the Impossible With Light)

The new spectrometers and other systems can observe the purity of raw materials. In the new reaction chambers, those systems can hover between nanomachines. And observe how the system advances the molecule formation. 

The nanodiamonds can act as, or with. The quantum sensor. The sensor is based on the quantum entanglement. And photon scanners can see even the positions of single electrons. The sensor works with the single photons that the system puts to send wave movement. 

Those single-photon scanners are the sharpest sensors that researchers can create. They can used to aim energy impulses into the single electron. This ability means that the system can shoot single electrons out from their orbitals. These kinds of sensors may not be so far in the future. The ultra-fast X- and ultraviolet radiation pulses can used to create the image of the atoms.

If there are channels in the quantum diamonds. Where there are even hydrogen ions (protons) or electrons that can scan the surface with impressive accuracy. In some ideas, the UV system freezes the electron that orbits the proton in hydrogen. Then the system inputs energy into the proton, and the electron acts as a stylus that scans the object.

"Scientists have achieved a groundbreaking milestone in quantum mechanics by manipulating the temporal evolution of a quantum system using extreme ultraviolet (XUV) light pulses" (ScitechDaily, Scientists Control Atoms With Light and It Could Change Chemistry and Physics Forever)

The ability to see particles. And their chemical bonds. Make it possible to create new chemistry. And that new chemistry makes it possible to create fundamental new molecules that revolutionize medical research. In the same way, those new molecular bonds raise nanotechnology to a new level. 

The ability to order the angle. And the point. Where two atoms, or molecules make contact. Is the thing. That changes chemistry forever. 

Light can blow the electron cloud into one side of the atom. Or a very sharp photon beam can shoot one individual electron away from its position. That thing makes it possible. That system can create chemical bonds for noble gases. 

Light or photonics is the new tool. That can make the new very complex chemical compounds possible. 

The new observation tools and fast-reacting energy-pumping systems along with highly sophisticated neural networks make it possible to manipulate atoms and molecules in new ways. The system can make the ultra-high accurate physical and chemical environment and aim the UV or IR and other monotonic radiation types to the objects with very high accuracy. 

The ability to send radiation into the individual electrons is the thing that makes the system more accurate and fundamental than developers ever imagined. The system can adjust the physical environment with UV and IR holograms. And those things can adjust the energy level in the atoms and their parts with ultra-high accuracy.

Researchers noticed that AI has its Achilles heel.

"Researchers showed AI models can be stolen by analyzing device signals, risking intellectual property and security. Countermeasures are now needed. Credit: SciTechDaily.com" (ScitechDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

The AI is the computer program.  Or a very complex computer program. With multiple layers. That means if somebody attacks the AI server that hosts the large language model, LLM. That makes it possible to steal the AI. Basically, that means the hacker can download the LLM source code into that person's own server. 

Researchers from South Carolina State University. Made an Attack on the AI server. Using electromagnetic waves. That means they didn't make a straight attack against the server. That means the server's firewalls and other things are helpless against the attack. The technology that those people used based the electromagnetic waves. 

"Researchers used electromagnetic signals to steal and replicate AI models from a Google Edge TPU with 99.91% accuracy, exposing significant vulnerabilities in AI systems and calling for urgent protective measures." (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

"Researchers have shown that it’s possible to steal an artificial intelligence (AI) model without directly hacking the device it runs on. This innovative technique requires no prior knowledge of the software or architecture supporting the AI, making it a significant advancement in model extraction methods." (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

“AI models are valuable, we don’t want people to steal them,” says Aydin Aysu, co-author of a paper on the work and an associate professor of electrical and computer engineering at North Carolina State University. “Building a model is expensive and requires significant computing sources. But just as importantly, when a model is leaked, or stolen, the model also becomes more vulnerable to attacks – because third parties can study the model and identify any weaknesses.” (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

"The researchers stole the hyperparameters of an AI model that was running on a Google Edge Tensor Processing Unit (TPU)". (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

So, by using this method. Researchers were able to determine the architecture and specific characteristics – known as layer details – researchers and later hackers, would need to make a copy of the AI model.

When an electromagnetic wave travels through another field affects its strength. That means. Things like radars that send electromagnetic waves through data lines can read data that travels in those lines. The idea is that the system acts like an X-ray system. It sends a radio wave through the data line and the sensor at the opposite side detects changes in that field and it can read data. 

The laser system that makes laser rays scatter can used to steal data from optical networks. Or the system can create a hologram around the laser ray. If the laser ray oscillates that hologram can steal information from those laser rays. 

If somebody can steal the LLM that is a very bad thing. Developing those things is expensive. But there is always some other possibility. Bad boys can use those stolen computer programs to create the evil twin for the use of China, North Korea, and Russia. In the wrong hands, the LLM can create virus codes and control cyber-attacks. 

Normally the ability to make malicious code is denied from legal or official LLMs. But in illegal copies, those abilities can exist. So, hackers can use those LLM evil twins for cyber attacks and industrial espionage. The LLM can also make cyber attacks on surveillance systems.

The ant-shaped robots are moving large stones.

Robots are multipurpose tools. And even small robots can move large objects if they act as groups. Ant-shaped miniature robots are excellent tools for many purposes. They can take samples from ant nests and search for things like fungus between walls. The miniature robots can make chains and deliver information from cramped places. 

They can observe cables and search for damages from tubes and electric wires. The use of those robots is almost unlimited. They can act in medical operations where they can operate as miniature surgical tools. The jaws of those robots can act as surgeon knives. The miniature robots can carry miniature sensors that can search for many things. The cloud-based calculation systems are tools that can make miniature robots operate independently. 

The non-centralized data architecture makes it possible to turn those robot's computers into one entirety. And that turns those robots into a deep neural network where they share their calculation capacity. 

That gives those systems the ability to drive quite complex algorithms. This gives them very high independence. Maybe one part of those swarms doesn't have very high-power processors. But if they act as an entirety, those systems can be very effective.

Those robot ants can go inside houses and deliver information about the enemy headquarters. In the military world, those small robots can slip into the computer centers and then cut wires from those computers. Or they can deliver the oil spill response microbe to fuel storage. The same microbes can be used against oil damage. But in the fuel tank, those microbes destroy the fuel.  

Miniature robots can also act as testbeds for larger-size robots. Large robots can also operate in swarms. That makes the robot swarm technology suitable for large systems. The car or lorry-size robots can also operate as an entirety. 

The new robots can act as legos. They can form larger structures that can remove themselves. The self-assembly materials make it possible to create self-assembly and self-repairing surfaces and structures. In those structures, the material is formed of the separated robots that can touch each other.

Cryofreezing can end death as we know it.

Cryofreezing or cryopreservation can make many things possible. The ability to freeze and thaw cells and organisms and return them back alive is the tool that can end death. There are many problems with those technologies. But it's possible to freeze a person into liquid helium and maybe someday we can wake that person alive. The problem is that if we freeze cells too fast they will damage. 

But if we would have nanomachines that remove liquids from the cells that give space for expansion that technology could turn death into the past. Another way would be the dry freeze.  In that technology, all liquids will removed from cells, and that thing makes it possible to freeze those cells. When the cell returns to life the system injects liquids back into it. The problem with humans is that we have very many cells. And that requires very advanced nanotechnology. But maybe someday in the future that is possible. 

The problem with cryonics is that a person is "sleeping". That means the person cannot communicate with others and that is one of the ethical problems of the cryostatic process. If we would send the cryogenic crew to other stars those people will never see their friends and families again.

The same problem is in the cases where a person waits for the cure for some deadly disease. That means when a person will return to life after 200 years there is nobody that person knew alive. That thing can make it possible to travel to the future. And that's why we can say that cryonic capsules are very slow time machines. And maybe someday we can return those frozen people to life. 

In some visions, the person uses the brain-computer interface BCI during their entire life. And that microchip stores all of the memories and brain activity into the computer memory. Then the system clones the person and then drives the data from the past body to the next body. Cloning the person might be made simple by exchanging the DNA from the morula. That is one thing that can turn a person back to life. 

Maybe in the future. We can use genetic engineering to extend our lifetime. The system must just create a cell that can replace old DNA and mitochondria with new and fresh DNA and mitochondria.

The genetically engineered Q-fever bacteria can transport new mitochondria. And DNA into the cells. 

The idea is simple. Genetically engineered Q-fever bacteria can travel into the cells. And destroy their mitochondria and DNA. And then replace those things with the new fresh DNA and mitochondria.

Can entangled particles exchange information faster than light?

When researchers put two elementary particles into superposition and entanglement. Researchers just make them oscillate synchronously. Information travels from the higher-energy particle to the lower-energy particle. And when a particle's energy levels are the same that forms a standing wave between them. 

That destroys the quantum entanglement. The requirement for quantum entanglement and superposition is that those particles are identical. The superposition is possible between two photons. But it's not possible between photon and electron. Superposition between simple systems like two photons is an everyday operation. Complex systems mean systems like baryons. There is more than one particle and that makes it hard to control. 

The superposition between complex systems like protons can happen by putting their down-quarks into superposition. And then the energy and information will flow between those two systems. The proton is the system. There are two up and one down quarks. 

And if the superposition is made between down quarks, that makes information possible to escalate to those up quarks through the proton's quantum field. It is also possible to put the two down quarks into superposition. And that makes it possible to create a quantum processor that is smaller than an atom. 

When the system starts to make the superposition it aims electromagnetic or acoustic waves to the transmitting side. First, the system drives information to the transmitting side. That system puts the receiving part in the opposite position. The system aims a laser beam at the transmitting particle. And laser beam forms a quantum shadow between those particles. That thing makes information travel between those particles. That system can be two frames where there is a trapped photon. The frame inputs data to the photon. Laser puts those photons in a superposition between receiving photons. 

But can information travel in superposition faster than light? The answer is yes and no. When the system makes the superposition it just makes a quantum tunnel between those particles. The tunnel forms when the laser beam starts to make the superposition.  Information can travel faster than usual in that quantum tunnel. But the photon is always the fastest particle. In that quantum tunnel or quantum shadow photons can travel faster than outside that tunnel.

Cosmic threats are always with us.

"Rogue planets may be numerous in the galaxy, but it surprises most to learn that there are between 100 and 100,000 rogue planets for every star in our galaxy, putting the total number of planets wandering through the Milky Way at somewhere around a quadrillion" (BigThink, Most planets in the Universe are orphans without parent stars)

The planetary defense is a thing. That we should think. The universe including our solar system is full of asteroids and dwarf planets. Some of them are small and we can see them at the last minute. And some of them are seen when they travel past the Earth. But the fact is that. Larger asteroids can cause larger threats than small asteroids. 

If about a 100-meter-size asteroid hits Earth. That will cause very large destruction. It's quite easy to defend cities and Earth against small asteroids. But if the problem is that if some Ceres-size asteroid comes to Earth we see that thing far away. 

And that means we have time to destroy that target. If there is lots of water on the asteroid the large-size nuclear weapon can detonate a hole in the ice that can cover the ocean. And then that erupting water acts like a rocket engine. That pushes the large asteroids away from their trajectories. 

But if a large asteroid like Ceres hits our planet that is the end of life here. In some horrifying scenarios, the large asteroid impacts the moon and then pushes it to impact the course of the Earth. Cosmic catastrophes can wipe any civilization into history and transform any planet into a cosmic molecular cloud. 

One of the threats is the rogue planets. Rogue planets can come into our solar system just like some asteroids. And a big rogue planet can turn the solar system into chaos. 

Most of the planets in the universe might be without parent stars. People call those planets as rogue planets. The rogue planet travels all around the universe. Some of them might be the result of a supernova or nova eruption. But it's possible. The planet can form spontaneously far away from stars, and that means. Rogue planets can be more common than we thought. 

The traveling planets are always a risk to solar systems. If a large, about Saturn-size rogue planet arrives in the solar system, that causes chaos. Those massive rogue planets will pull the asteroids and moons from their trajectory. But smaller rogue planets can also pull things like asteroids from the Kuiper belt behind them. 

The thing is that the threat of rogue planets is real. And if we face a situation where a rogue planet arrives in our solar system. We would need a very powerful tool. That can turn that planet away or crush it. The antimatter bomb can destroy a large planet. And then the laser systems can destroy those asteroids that will travel to our solar system. Or we can just sit and wait for the impact. 

The choice is that we will stand without making a thing. That can mean that the large object can impact Earth. If Earth impacts with a Mars-size planet that will be the end of our world. The thing is that the small rogue planets might be planets that the star explosion pushed away. And large rogue planets can be planets that formed outside the star's gravity field.

New Chinese weapons are terrifying.

The Chinese nuclear submarines can launch long-range submarine-launched ballistic missiles, SLBMs, quite soon. Those new weapons are equipped with new nuclear warheads that can have hypersonic glide capacity. That means that the very high-power medium-range DF-17 with hypersonic glide vehicle, HGV called DF-ZF. 

Can fitted to those new nuclear submarines. The thing is that those hypersonic systems are deadly tools. The DF-ZF gliders can also mount to the longer-range ballistic missiles. And Chinese can use them against aircraft carriers and other targets that can be far away from the coastlines. The long-range hypersonic missiles can be the top priority in Chinese military doctrine. 

The idea is that those land-based conventional- or nuclear missiles can be tools that can threaten enemy forces around China. But crews of those systems stay under control. The hypersonic missile can also use the kinetic energy. The speed of those weapons is so high, that they are dangerous without warheads. The speed of a hypersonic drone can be four times higher than famous GAU-8 cannon ammunition. 

And their mass is many times higher than the 30 mm. uranium ammunition. The hypersonic missiles are a big threat. The ability to install those weapons into nuclear submarines is the next step to raise the Chinese fleet strike capacity. The technical advances in the Chinese military have been faster than anybody predicted. 

The next step in that case will be that China will modernize its nuclear submarine fleet. That means China will replace its old, noisy diesel-electric submarines with new nuclear-powered systems. The new innovative propulsion like plasma-pulse engines will give those submarines very powerful attack and stealth capacity. 

Above: Chinese mobile launcher DF-17 with DF-ZF (WU-14) Hypersonic Glide Vehicle.

The electromagnetic rail guns and other new weapons give that military force a new way to complete things like amphibious missions. The intensive hacking and intelligence work might make the new advancements possible. The thing is that China will want to become a global superpower. 

The problem with the Chinese military is that the Chinese economy and entire society are harnessed to serve the People's Liberation Army, PLA. That means that the Chinese military is the center of the China. This means there is no similar resourcing in the West that breaks the investments into the PLA's strike capacity. 

The fast-advancing technology in the Chinese military causes problems with NATO. The U.S. military has problems focusing its newest technology in the case of crises. That started at the same time in Asia and Europe. The elder F-16 and F/A-18 might have problems with Chinese J-20 multirole fighters and the new hypersonic strike capacity. In the same way, this new strike capacity forces the U.S. and its allies to put more money into more expensive military systems. 

That means the Western military grows old faster than we expect. The new advances in quantum computing give the Chinese military forces new ways to make powerful new tools like new stealth bombers and fighters along with new hypersonic stealth missiles that can give powerful surprise attacks. To any target around the world.
