The F-35 and the US ballistic missiles need the key component of a magnet. The problem is that it was “Made in China”

Finally, China carried out what the global industry feared: blocking the export of rare earths more valuable. In this way, without more, it sounds tremendous, although surely many will wonder how far the scope of the veto really comes, or which supply chain will be affected in the short term with Beijing’s decision. There are many sectors against the strings, but there is an especially delicate one for Washington: Defense. If everything remains the same, you have a few months left for your F-35 or ballistic missiles to have a serious problem. The Achilles heel. I told it The New York Times A few hours ago. China’s decision to impose restrictions on the export of critical minerals and, especially, of certain rare earth magnets, represents a direct warning to the national security of the United States, whose military capacities They depend largely of these resources. Which is it? We talk about Combat fighters of the Air Force, like F-35of guided ballistic missiles of the army or electric drones of the Marines, where these magnets (made with elements such as neodymium, disposium or ititrium) are essential for the operation of motors, guidance mechanisms or emergency systems. If, for example, a ballistic missile does not include the component of these magnets, it would be impossible for their goal to reach. The background problem. That 90 % of these components are produces in Chinaand six of the key metals that compose them are only refined there, which gives Beijing a powerful pressure tool. This maneuver, considered a “warning shot” by An official From the Air Force, it could easily climb towards fees, tariffs or even a total prohibition, generating an immediate impact on the costs and availability of American military technologies. A vulnerable chain. It We have counted other times. Rare earth (a set of 17 elements) is not that they are scarce in the strict sense, but its processing is expensive (and polluting), which is why China managed to dominate both its extraction and the associated refining and manufacturing. This supremacy has allowed him control much of the final cost of the modern American weapons, including those poachers, submarines, war ships, tanks, missiles and laser systems. To get an idea, only one F-35 contains around 400 kg of rare earth materialswhile some submarines They exceed 4,000 kg. Although the American defense industry and the pentagon have accumulated strategic reserves of these elements, analysts warn that these collections would barely reach to cover a few months of production and maintenance, not even years. From there, as we recently counted, that Washington has noticed the Pacific fund. Future warnings. Actually, the United States already knew about this unit and what could happen for a few years. It happened with an emblematic case, the call “F-35 “magnet debacle”when in 2022 the Department of Defense temporarily suspended the delivery of these aircraft after discovering that a component contained a Alloy manufactured in Chinacontravening defense acquisition standards. Although at that time it was considered that the material did not represent a direct threat, the incident highlighted the depth of the US dependence. Now, with the obligation that Chinese exporters Request special permits Before sending rare earth to the United States, experts anticipate a price increase that will affect the entire industrial defense base. Yes, the MINTAIN PASS MINA In California it has resumed operations, but its production is far from competing with Chinese capacity. Historical precedents. Looking back, history offers examples of how the United States must have adapted to interruptions of the supply of strategic materials in times of war. For example, now It happened with the bauxite During World War II, when Germany sank allied charges that transported it from Surinam. So Washington turned to Domestic reserves in Arkansas to guarantee the production of airplanes. Today, The Times told that there are already voices from the sector, such as American Enterprise Institutewhich insist that current reserves are not enough to sustain the military-industrial complex in the face of a long interruption of the Chinese supply. Despite the initiatives of Trump and Biden governments to Reactivate national production Of critical minerals, the industry remains highly vulnerable to Beijing’s decisions. A critical dilemma. No doubt, there is a much broader background with what happened in the commercial war. Chinese control over rare earth supply not only implies logistic or economic vulnerability: it represents A geostrategic challenge First order for the technological supremacy of which the United States has always presumed in the military. The recent Chinese measure does not close trade routes completely, but it makes it clear that Beijin possesses A pressure lever Formidable about the American defense industry. Faced with this, analysts agree that Washington must accelerate efforts to diversify their sources of supply, recover internal industrial capabilities and ensure the resilience of a supply chain that supports a good part of its global power. Otherwise, the next crisis may not limit yourself to that “warning shot”, but to become a direct blow to the technological backbone of the National Defense.

China wants to revolutionize the hypersonic flight of airplanes and missiles with an explosive ingredient: magnesium

China and the United States are immersed in a race that is not fought on the mainland, but in the air with a common goal: to achieve speeds of more than 7,000 km/h. Both have several hypersonic airplanes projects With potential both military and civil And, although the US seems more reserved, China from time to time goes out to the arena to talk about Your technological achievements. The latest is an engine capable of going to Mach 6 thanks to a fuel formula with a special ingredient: magnesium. Mach 6. When we talk about hypersonic speeds, what we use to measure it is the Mach 1. is the one that represents the speed of sound, established in 1,235 km/h. Thus, a Mach 2 speed would be twice the speed of sound. Well, what are testing At Beihang University in Beijing it is a technique that allows to double the thrust of current hypersonic engines to reach Mach 6 and higher speeds. It is difficult to get an idea of ​​the amounts we talk about, since we are talking about speeds of more than 2,000 meters per second or around 7,000 kilometers per hour. It would be like going from Madrid to New Delhi in an hour. That journey, currently, has between eight and ten hours. EITHER cross the Atlantic in three. Scramjets. The objective of the researchers is to redefine hypersonic aviation thanks to a combustion technique that, as we read in South China Morning Postpractically doubles the thrust of a scramjet engine. It is the abbreviation of “Supersonic Combustion Ramjets”, these Ramjets being reaction engines created to reach Mach 3 speeds. To function, the air enters the engine at high speed. They are motors without turbines that compress that air at supersonic speed (do not slowly subsuite like Ramjets) and then the fuel is injected. It can be hydrogen, but also kerosene, which is mixed with compressed air and, as a result, a supersonic jet of hot gases that propels the vehicle is generated. When it occurs for the first time, it is when the sound barrier is broken and something similar to an explosion is heard. “Secret” ingredient. The problem of Scramjet engines is that, at extreme speeds, the energy generated by fuel is stabilized, but adding magnesium to the fuel formula, the thing changes. The Chinese team chose magnesium being a metal with a violent reactivity. When the kerosene burns it generates residual, but when they inject magnesium dust, that CO₂ acts as an oxidant lighting the magnesium particles. Yang Qingchun is the project director and comments that “magnesium does not need atmospheric oxygen”, so those magnesium dust particles react in explosive shapes with the residual gases that were previously wasted, now releasing an additional energy. China hypersonic test vehicle Evidence. And they have tested. Under conditions that simulate a Mach 6 to 30 kilometers altitude flight and using commercial aircraft fuel, magnesium injection increased the thrust by 86.6% with a combustion efficiency of 65.1%. This allows to increase the 613 Newtons-second motor thrust per kilogram at 1,126 Newtons-Second per kilogram. At that speed, the kerosene burns practically completely, the magnesium dust turns to the contact and releases the heat between two and three times faster than only the kerosene. But speed is not the only advantage. Something crucial is not to overheat the turboreactor, so researchers have studied how to optimize the process to increase performance without a temperature increase. Thus, it is the kerosene that acts as a refrigerant of the motor walls through regenerative cooling. The magnesium, which is added later, burns in a “storm of supersonic fire”, according to the researchers, which is stabilized thanks to an optimized flow route that, in turn, helps to achieve that more powerful thrust. Challenges. But of course, the higher the speed, the greater the challenges. We have already commented that the temperature is something that plays against supersonic ships Because they must resist friction that makes the temperature rise above 1,500 degrees Celsius. In addition, at more speed, more turbulence. The team states that this supersonic turbulence entails the risk of an unequal dispersion of magnesium dust inside the postquemor. If there is a bad penetration of the particles, or an irregular injection, the thrust gain falls to almost 20%. It is something that causes the engine to be very unstable. In addition, those magnesium particles that “exploit” are a double -edged sword. On the one hand, the explosion generates that violent reaction that increases the thrust, but at the same time the particles become microcuchillas that can damage the engine. Therefore, you have to investigate engines with the capacity to resist impacts inside. On the other hand, you have to stabilize magnesium injection because it is postulated as something ideal to quickly reach hypersonic speeds and maintain them, but a ship fluctuates in speed, it is an unstable fuel. They have added nitrogen gas to stabilize the entrance of the particles, but the team confesses that it is “as difficult as threading a needle in the middle of a hurricane.” Projects. It is something that China will continue working because it is the team itself that states that it is not something only for airplanes: Yang comments that its design can reduce the launch weight or extend the range of missiles. They will try to inject magnesium on a nanometric scale to see if it is more efficient, but it is clear that it is a project that interests the country. And, yes, China has already tested higher speedsbut what they are looking for is more stability and the way to change between speeds at pleasure, not in such a linear way. And he does it because the United States is also working on it. Not only in aircraft like Blackbirdbut also in systems such as Dark Eagle, a missile with a range of more than 3,000 kilometers and capable of reaching speeds greater than Mach 17 (about 20,000 km/h) with systems to … Read more

stop the development of their hypersonic superorders and missiles

The US has just taken another step in The climbing of the tension that holds with China. The administration led by Donald Trump He has inherited a long list of Chinese companies To which US companies cannot sell them their technology, they can do so only under a very strict supervision of the Department of Commerce. For a few hours in that “blacklist” there are 80 more companies. According to Nikkei Asiathe US Industry and Security Office has decided to expand perceptibly the list of sanctioned companies because “they have carried out actions contrary to the US national security and foreign policy.” However, although most of them are China, not all reside in the nation led by Xi Jinping; Some come from United Arab Emirates, South Africa, Iran, and even Taiwan. Chinese hypersonic weapons are in the spotlight of the USA That the US administration has decided to sanction Emirati or Iranian companies enters within the foreseeable, but that the sale of American technology to Taiwanese companies a priori is also surprising. However, It is not so much. Not at least if we stick to the justification argued by the US government in these cases: all sanctioned companies are Chinese, or collaborate with Chinese entities, or represent a threat to national security. “American technology should never be used against the US people” Whatever the purpose of the US on this occasion, it is not exactly the same as it pursued with Other sanctions packages. Some of the vetoed companies are dedicated to the development of the artificial intelligence (AI) or Superorganizers with Exaescala processing capacity. This is not new. However, others, presumably most, are directly or indirectly involved in Hypersonic missile development or latest generation drones. Jeffrey I. Kessler, Undersecretary of Industry and Security of the Department of Commerce, has pointed out that “American technology should never be used against the US people (…) Donald Trump’s administration is sending a clear and forceful message to the purpose of safeguarding national security by preventing US technologies and goods national”. At the moment the Chinese government has not officialized any responsealthough in all likelihood It won’t stay with crossed hands.

Argentina fought the British missiles with a paste machine

Battles and wars always leave winners and defeated, but in some cases they occur Unexpected surprises due to the apparent advantage of some and the surprising outcome with the victory of the other. There are stories like the The Invasion of the United Kingdom trying to conquer Tenerife without knowing what was inside. The one that occurred in Malvinas had the expected endbut what nobody could imagine is what Argentina was going to defend. An unequal war. The FALVINAS WAR (1982) faced the Argentine Air Force (FAA) against the United Kingdom in a conflict where British technological superiority It was more than evident. While Be British Harrier They had advanced radars and missiles AIM-9 SidewinderArgentine airplanes lacked radar alert systems and electronic countermeasures. Moreover, the A-4 Skyhawk, Mirage III, Dagger and Canberra they operated without self -defense systems against radar -guided missiles, such as the Be dartlaunched from British destroyers. The pilot Pablo Carballo, veteran of Malvinas, He explained years later To a United States Air Force officer that Argentine pilots were not afraid when a radar alert receptor was activated because their planes simply did not have one. That lack of equipment left FAA with a single option: resort to ingenuity to create its own countermeasures. Electronic countermeasures. The so -called Like Chaffused from World War II, consists of metal strips that enemy radars saturate With false signals. It would be something like the measures/lures against electronic of our time. Plus: Argentina had detailed information about British radars, since the Navy operated two Type 42 destroyersHMS Sheffield twins. With a “but”: the FAA did not have an industry developed to produce large -scale Chaff, so they turned to the most improvised media. Be British Harrier The secret is in the pasta. The first production attempts began in the Military Air Base (BAM) Comodoro Rivadavia In May 1982. By not having specialized equipment, a group of officers devised a rudimentary method: Students recruited from the province of Entre Ríos to cut hand -to -cut strips. The problem? Production was insufficient. As they counted In The War Zoneit was then that a technical noncommissioned officer proposed an unusual solution: use a Industrial Machine for Pasta and noodles. That machine, borrowed from the Napoli pasta factory, had blades of the exact size to cut the aluminum strips efficiently. Thus, the team worked 24 hours a day for a week to make enough Chaff that could be used in combat. Deployment and difficulties. With the insured production, methods to launch the chaff were improvised from the airplanes. In it Mirage III and Dagger rolled chaff strips in packages wrapped in toilet paper and adhesive tape, which then They placed in the aerofrenos of the airplanes. This had a problem: the pilots opened the aerofrenos during the flight to maneuver, which could make the Chaff disperse before being useful. For The C-130 HerculesChaff was placed in bags tied with three -meter strings, which were thrown manually from the rear doors to create an interference curtain against enemy radars. Finally, with the Canberra MK 62 It was with the only unit that a partially successful system was used. Seven pitchers were installed in the back, with cartridges containing Chaff and Bengals. A Douglas A-4 Skyhawk of the Argentine Air Force in 1982 The “D” day. Thus, on June 2, 1982, the system was approved in a A-4C Skyhawk with launches from different altitudes, although No effective results were achieved. Other attempts included the use of FFAR rockets to disperse Chaff and the modification of Shafrir Missiles 2although none was really viable. Use in combat. On May 1, 1982, during a mission of bombing on the British forces, three Canberra MK 62 took from Trelew with the Chaff system and flares. The pilot Eduardo García Puebla reported how He managed to avoid Two missiles AIM-9L Sidewinder launched by a Sea Harrier thanks to the use of the improvised system. However, another Canberra failed to activate his flares and was shot down by a British missile. Days later, another Canberra was destroyed by a missile Be dart of HMS Cardiff without even having deployed Chaff. It is not clear if the countermeasures were really effective in some other episode, mainly because the British reports did not mention deviated missiles by these techniques (and it is very possible that they did not even know). The legacy. The end of the contest It is known (Although never It has ended at all). After 74 days of battle certainly unequal, the United Kingdom recovered the Falkland Islands. The conflict ended exactly on June 14, 1982 with Argentine surrender. However, FAA’s attempt to use chaff manufactured by hand With a pasta machine It is a testimony of ingenuity and determination in conditions of technological inferiority. Although the system had rather limited results, it demonstrates how in war the resources available can become improvised solutions. For the history of the contests, the only known conflict where a pasta machine was part of the military countermeasures.

North Korea tests cruise missiles from the sea

North Korea tried strategic cruise missiles launched from the seaannounced the state press agency KCNA, adding that the missiles reached their objective with “precision.” The North Korean president Kim Jong-un, who according to the agency attended the evidence, said that “the means of deterrence of the Armed Forces of the Democratic People’s Republic of Korea are more deeply perfected.” The missiles reached their goal after traveling 1,500 km trajectories In the form of eight and elliptical, Kcna said, without specifying where the tests were carried out. He said that “there was no negative impact for the safety of neighboring countries.” This is the first trial of North Korean weapons since Donald Trump’s return to the White House. Shortly before his presidential investiture on Monday in Washington, North Korea triggered several short -range ballistic missiles to the sea. Trump, who held several meetings with Kim during his first government, said in an interview released on Thursday that he would contact the North Korean leader, which he called an “intelligent type.” Continue reading:• Historical Defense Treaty between North Korea and Russia between officially in force• North Korea enlists more troops and “suicide drones” in support of Russia, according to Seoul• North Korea and Russia ratify Treaty of Defense and Immediate Military Aid (Tagstotranslate) North Korea
