May your cat ignore that appetizing food has a scientific explanation. Is called neophobia and it’s life insurance

by

You open one of the littleirs that you have bought your cat and flips with the good f see, it almost makes you want to try it, but when you offer it, all bad. It smells it, looks at you with contempt and leaves. Yes, it has happened to me and I have thought that my cat enjoyed watching me money on food that was not going to eat. Your cat does not hate you, it is its nature. Food neopobia in cats A search on the subject returns hundreds of results of Tutors asking for advice to get their cat to eat something new and tips to get it. The most common are usually cats that reject wet food and They just want to eat their feedwhich is not recommended because it can lead to the dreaded kidney disease. What happens to cats? Neophobia is the fear of something new, in this case new foods. Although food neophabia is not exclusive to cats (It also happens in humans), it is a fairly common behavior in cats and one of the reasons that have made them win the Fame of Sibaritas. It is not a feline whim, it is pure instinct, An adaptation strategy to protect yourself from possible poisoning. It is not a feline whim, it is pure instinct, an adaptation strategy to protect itself from possible intoxication. Beyond the inheritance of its wild ancestors, neophy and domestic cats may appear for other causes and one of them is stress. Cats are very sensitive to changes. In This study They analyzed stress in cats and the consequences it can have on their behavior and health. A stressed cat tends to eat less, but it is also more prone to develop neophobia. If a new meal is offered in a stress situation, it is more likely to reject it. Cat’s food preferences In This complete article of Vet Times magazinedelve into the mechanisms that form the food preferences of cats. In his first months of life he is strongly influenced by his mother’s. In fact, this influence begins even before birth, by transfer of flavors through amniotic fluid and milk. It has been proven That the kittens whose mother ate unusual foods in the cat such as milk or banana, showed inclination for these foods. “Eat it” Genetics only plays a small role, but the food to which the cat is exposed in their first months of life will be decisive when forming their adult preferences. In this sense, a kitten that only eats a type of food is more likely to develop neophobia towards unknown foods, while A more varied diet will become familiar with more flavors and textures. Experience is another decisive factor and is the one that is defining how the cat selects food during your life. For example if they eat something and feel bad, they will create a negative association and will not eat it again. The food to which the cat is exposed in their first months of life are decisive when forming their adult preferences. Of course it also influences palatability, that is to say, how nice the smell, taste and texture find of a specific food. As strict carnivores, they are attracted to protein -rich foods and tend to reject bitter or sweet flavors. In the case of feed addicted cats several factors come together and palatability is one of them. Feed manufacturers have “hacked” the feline palate with flavor enhancers (palatal) to make them more attractive and want to eat it all the time. If we add that we usually have the feed at the disposal of the animal, the habit is reinforced to the point that some cats do not want to eat anything else. In addition, the crunchy texture of the feed further reinforces that preference, making wet food something strange to them. My cat rejects food. What I do? The first, be patient. Getting a cat with a very strong neopobia start eating new foods is a background race. The first step is Get familiar with the new food. In This study He gathered fourteen adult cats that showed neophobia towards a lamb flavor food. What they did was vaporize the smell of food while cats ate their usual food. The result was that neophobia was reduced considerably. I like this. You can start by putting A bowl with wet food by feedso that I associate that it is a safe food. It is important to offer variety, because it can be the case that we are determined to eat a single option and that it turns out that you simply do not like. If your cat does not eat any wet food, there are Nutritionists who advise starting with little cans that are unhealthy. The reason is that they usually have a very attractive and flavoring smell more similar to those of the feed. In this way, it is first familiar with wet food and little by little you can introduce healthier cans. It is also recommended slightly heat the fooddo not give it directly from the fridge because it will almost certainly reject it. To start eating something new, the obvious is important: to be hungry. I think freely is not recommended. To start eating something new, the obvious is important: to be hungry. In this sense, I think freely 24 hours is not the most recommended. You can serve food three or four times a day or use An automatic feeder. Yes indeed, A cat should never be more than a whole day without eating since it can develop Hepatic lipidosis and even die. Each cat is a world and There are many more tricks That you can use, such as soaking or crushing the feed and putting a little on wet food. Also You can use others TOPPINGS like a churu -type liquid snack and sprinkle supplements such as Fortiflora (is a probiotic) or Green lip mussel powder. In Xataka | Genetics offers … Read more

In Japan, the average trains delay is 96 seconds. It is not magic, his secret is called “Paka-Yoke”

by

We are not going to discover anything if we tell you that the high Spanish speed has not lived its best summer. To get an idea, Four out of 10 Renfe trains They have suffered some type of delay. We have had breakdowns, Lost trains during the night and the final tip of the fires. But beyond summer, the truth is that the Spanish road network is giving important symptoms of fatigue. Only last June, The birds arrived with a medium delay of 19 minutes About the scheduled time. In April the figure was almost 21 minutes. According to the published report by the company, of the 9,607 trains that circulated last June, only one in three arrived in time Or they were delayed less than five minutes. We know this because Renfe herself has published it but the breakdowns have also affected the trains of Iryo and Ouigo that have to circulate on the same ways. The data point to two possible reasons. First, Spain begins to give symptoms of having an infradimensive infrastructure to host the arrival of new operators (OUIGO and IRYO) and a Growth sustained in the number of trips. Second, the data warn that not enough has been invested in maintenance and modernization of the roads. It is very likely that the situation we are living is a mixture of both reasons. But a question overwhelm: if in Spain we have problems with three trains companies … how do they work in Japan where six different companies operate? 96 seconds Move by Japan, especially for Honshu (his main island in which cities like Tokyo, Kyoto or Osaka are found) is very simple if you decide on the high -speed train. The frequencies are so bulky and the delays so exceptional that the reliability in the system is absolute. The known as Japan Rail It can, also, be chaos for those who visit the country for the first time, taking into account that even Six companies operate on their lines. However, each of them has its own reserved space so they do not compete on the same roads as it happens in Spain where Renfe has to deal with Iro and Ouigo. Despite this, four of those Six companies (JR East, JR Central, JR West and JR Kyushu) are completely privatized and only two (JR Hokkaido and JR Shikoku) are state -owned. There is, however, a fundamental difference. In Spain, following European orders, the management of the roads falls exclusively on Adif (which was public and also had to be privatized) that charges some canons to companies that want to operate in their railway framework. AND The roads are shared partly between medium distance and high speed trains. In Japan, however, companies manage infrastructure and maintenance of the roads in which they operate but the network of Shinkansenthe famous bullet trains, have a completely separated infrastructure from the rest of the trains and is managed by the Railway Construction, Transportation and Technology Agency of Japan (JRTT). This physical separation allows to reduce the risks (a fault of a slower train does not impact bullet trains) and install systems specifically designed for this type of trains. That has allowed them to evolve the acquaintance concept of Paka-Yoke which can be translated as “failure proof”, referring to the fact that all human decisions are supervised by an exahustive system monitoring system, which shields the network of those possible human errors. This has allowed Japan to be a reference in world high speed. Until Spain and China surpassed the country in railway kilometers of this type of trains, the Japanese country was a leader but it still is in punctuality. In 2024, The average delay in the Tokaid line was 96 seconds. However, systems are designed for trains to enter a margin of 15 seconds at the station. Most of them stop in the first 6 seconds scheduled. Japanese punctuality is an extremely valued quality. Culture forces to ask for public forgiveness when schedules are not fulfilled, sometimes reaching surreal extremes. Like the day that a railway company had to make its face because one of its trains He left the station 20 seconds earlier than expected.

There is a reason why Oracle has become the new beautiful AI girl. That reason is called Project Stargate

by

OpenAI has reached an agreement with Oracle for which it has pledged to hire computing capacity worth $ 300,000 million within five years. The data come from The Wall Street Journalwhere sources close to that agreement cite. The implications are huge. Why is it important. Yesterday Oracle shot in the stock market after announcing that he had had good results, but above all Future income would increase by 359% up to 455,000 million dollars. Although there were suspicions about what could have happened to that extraordinary growth, we now know what happened. And what happened is the Stargate project. The numbers do not fit. The agreement will begin in 2027 and priori seems very risky, especially since OpenAi has no money. Its annual income will be about 10,000 million dollars in 2025, but will have to pay for 60,000 million annually to Oracle to comply with the agreement. Not only that: Oracle will also depend on receiving that income, because now a large part of them will come as a single client. As they point out in WSJ, Oracle is likely to have to borrow to buy the chips necessary to create those data centers that OpenAi will use as part of the agreement. 4.5 GW of calculation power. The contract will make OpenAi access a 4.5 GW computing capacity. It is a way to measure the energy consumption of the center or data centers that will be used to serve the firm’s AI models. The figure is huge, and to put it in perspective, it represents almost 40% of the entire current computing power of Europe, which amounts to 11.9 GW According to IEA. The Stargate Resurge project. The announcement of the Project Stargate, which raises an investment of 500,000 million dollars in data centers for AI, returns to the present. The accounts seem not to leave Despite the recent idyll Between Openai and Softbank, but in July the company of Sam Altman announced that his company and Oracle They had arrived to “an agreement to develop 4.5 additional capacity of capacity in Stargate data centers in the United States.” More bubble indications. The agreement between Openai and Oracle is absolutely huge and confirms that disturbing tendency of the extraordinary expense in data centers that we have been living for months. That figures dance states with the fact that for now all the companies of AI are burning money as if there were no tomorrow And they are far from profitable. That has caused alarms and alerts to be triggered on a IA bubble potential. Microsoft begins to go to the background. The agreement confirms that progressive separation Between Openai and Microsoft, which after the multimillionaire investment of 2023 had become the great technological partner of OpenAI. Each of these companies this now working in their respective plans b. The contract between Openai and Oracle makes that separation of roads once clearer. Doubts about Oracle. This agreement has turned the company into the new beautiful AI girl, but it is not clear if you can fulfill a commitment as ambitious as the one that arises with this contract. To begin with, Oracle has many more debts regarding the money in cash, and its debt ratio on heritage (Debt to Equitiy) is 427%, a very high figure. Microsoft in comparison has 32.7% according to S&P Global Market Intelligence data cited In WSJ. A huge challenge. In addition Microsoft had a cash flow of 136,000 million dollars for the fiscal year that ended this June, while its Capex was 88,000 million dollars. Meanwhile, Oracle had a cash flow of 21.5 billion dollars and its Capex was $ 27.4 billion. Its capex in the coming years will have to shoot, and it is evident that the company has a huge challenge with this project.

There is only a great beneficiary at Ryanair’s departure from regional airports. One called “High Speed ​​Train”

by

Ryanair threatened and fulfilled. As he turned a few months ago. The company confirmed yesterday, September 3, which removes more than one million places from regional airports. In total, its activity will be reduced by 41 % in this type of aerodromes and 10 % of its activity in the Canary Islands will also be affected. The movement has unleashed an wave of indignation among Spanish institutions that qualify the exit as blackmail or extortion. The company, meanwhile, defends itself by ensuring that the increase in Aena’s rates are incompatible with its operations in this type of airports. But what the movement leaves us is the confirmation that regional airports are less and less competitive. A good part of them have based their operations on a huge dependence on the company. And the Good train health It is making operating in them, more and more complicated. A good example is that the company will increase its operations in larger airports. The controversy As we explained yesterday, with its latest Ryanair movement it will reduce 400,000 places in the Canary Islands in winter, being the autonomous community most punished by volume. In total, 36 connections are canceled. It remains to be seen if the flights to the Canary Islands are held by other companies. A good example is the Binter expansion that in recent times it has begun to increase its routes in the connections between peninsular Spain and the islands. In addition, Ryanair has announced the closure of Santiago de Compostela and the suspension of all flights to Vigo as of January 1, 2026. It maintains the closure at the airports of Valladolid and Jerez de la Frontera. And will reduce its operations in Zaragoza (-45 %), Santander (-38 %), Asturias (-16 %) and Vitoria (-2 %). The company attacks Aena and the Government, to whom it accuses of “failing to the Spanish regions, whose airports are almost 70 % empty.” For its part, the airport manager attacks that “the communication and institutional relations policy of Ryanair is guided by Phariseism, bad education and blackmail”, while trying to “falsify reality.” All these words pick them up eldiario.es from the mouth of Maurici Lucena, president and CEO of Aena. The excuse Ryanair has used to abandon or reduce its operations at these airports is at the rise of Aena rates. Those rates are the ones guarantee basic services of airports such as cleaning or safety, to put only some examples. At the moment, there are substantial discounts than in airports with the lowest volume of passengers make them insignificant. On the contrary, where it is paid the most is in the airports of greater volume. That rate has been frozen in recent years but will rise if the CNMC approves it. From the beginning, the company’s opposition has been found. They defend that in countries such as Italy, Morocco or Croatia have been lowered to attract tourism and that, with these increases, “Spain is closing” to the same. A statement that The data denies. According to Aena, The increase is just 68 euro cents By passenger but they put the company that their rates have increased by 21% in the last year. But this is just the surface. Spain is not the only country in which Ryanair has reduced operations. The Irish have also retired more than 700,000 places from the French regional airports. And it is also not accidental that their operations to Morocco travel almost empty. For a long time, the company has exploited institutional advertising to maintain open paths that would not be profitable without these substantial pluses. In fact, that Ryanair trip to Daklha is only explained since The interest that Morocco has in exploiting that areanear the Sahara, as a holiday destination. Ryanair as a symptom And the train as a disease that hurts regional airports. To all of the above we must add the loss in competitiveness of many of the airports of which Ryanair leaves. The company has closed operations in Santiago and reduces its connections in Vigo. Casually there are two cities to which The arrival of high speed is especially affecting. Until not so long ago, the only way to travel quickly between Madrid and Galicia was by plane. Now, the High speed It allows you to reach the center of the capital more or less the same time as you travel by plane. And without the discomforts of this means of transport. In Asturiashigh speed is not yet working in full performance but the opening of new sections (and others on the horizon)place the region in a position where the train, again, will compete with the plane for faster connections. It will remain faster to travel by plane but its connection with Madrid is already competitive by train. What to say about Zaragoza where in recent years Renfe has joined Ouigo and Iroyo. The corridor maintains a hard competition And although the tickets are not the cheapest on the market, the volume of trains is very high and the latest connections already allow Zaragoza to be linked with Galicia in four hours (making transford in Madrid). In addition, the possibilities to get to Seville or Malaga are multiple with the aforementioned Renfe rivals. Eliminate air connections with the main Spanish cities should result in greater use of this means of transport. And from Aena they are clear that reality is “more prosaic.” “Ryanair moves her planes to airports where can set higher prices In their plane tickets and earn more money, such as Great Spanish airports“, despite being” substantially higher, “they insisted on words collected by RTVE. In Santander, where connections with Madrid are not so advanced, four international destinations have been withdrawn (Rome, Milan, Vienna and Paris) but the flights to Valencia and Malaga are maintained. In Santiago, however, connections with other Spanish cities die. And in Vigo he retires from the line he had with London. Casually when the contract ends Between the City Council and the company … Read more

A group of young people has become Milmillonario in less than three years: their lottery ticket is called Ia

by

Artificial intelligence is starring An economic revolution unprecedented that is generating one of the greatest jumps In wealth creation In recent history, something that Such and as stood out Bloomberg, The exponential growth of this developing sector has resulted in the accelerated appearance of New billionaires. Most of them are young entrepreneurs who have seen His fortunes multiply Thanks to the assessment of their AI companies for risk capital investors. A magnet for investments Andrew Mcafee, MIT principal researcher, pointed to CNBC that this generation of wealth “is not preceded” in the last 100 years of which there are records. In Xataka Jensen Huang presumes more than chips for AI: he has created more billionaires than any other CEO According to data of CB InsightsThere are 498 companies dedicated to AI with valuations above 1,000 million dollars and more than 1,300 startups valued at more than 100 million dollars. Estimates From the study they set that, together, these companies have a value of 2.7 billion dollars. The most curious thing is that, at least 100 of those unicorns of more than 100 million dollars were founded after 2023, which makes the phenomenon even more striking for its effervescence. This AI boom has become An economic engine which already exceeds the investments generated by other technological revolutions such as Internet, electronic commerce or social networks, whose companies are also betting strongly on AI. However, unlike what happened with the Puntocom at the beginning of 2000. Companies that are providing huge fortunes to their founders are not public contributions, but are maintained as main source of wealth for Its founders and managers for maintaining greater control over your participation percentage. In Xataka In silence, the engineers specialized in AI are becoming the best paid workers in history THE NEW MAIN VETA TO MAKE MILLIONARY In the last decade, social networks or the different electronic commerce formulas marked the pattern as the main ways of creating millionaire fortunes. They abound The examples In the current list of millionaires with names such as Jeff Bezos or Mark Zuckerberg. However, now it is the AI ​​who is rapidly replacing these sectors as the fastest source for generating a substantial fortune. According The published By Bloomberg, the development of AI has led to the raising of at least 15 Milmillonarios entrepreneurs, with a combined heritage of 38,000 million dollars. Companies such as Anthropic, Openai, Safe Superintelligence or Anysphere have starred in millionaire financing that have led their founders to reach fortunes of more than 1,000 million dollars in a very short time. A remarkable example is Anthropic, which negotiates an investment round that could place its valuation at 170,000 million dollars, almost tripling its value in a few months. Openai, has become the startup with greater assessment reaching 500,000 million dollars in its last investment round. The previous one stayed at 300,000 million, which leaves an idea of ​​the speed of Growth of these companiesand with them, the fortunes of its founders. {“videoid”: “x8jpy2b”, “Autoplay”: fals, “title”: “What is behind it like chatgpt, dall-e or midjourney? | artificial intelligence”, “tag”: “Webedia-prod”, “Duration”: “1173”} Alexandr Wangco -founder and exco from the startup Scale AI, he became at 28 years the youngest billionaire in history, with an estimated fortune at approximately 3.6 billion dollars.

The US has bought 10% of Intel to save it from burning, and that plans a huge problem. One called favoritism

by

Intel has agreed to sell 10% of your company to the United States for a value of 8,900 million dollars. An interventionist measure is thus confirmed that has huge implications not only for Intel, but for the entire semiconductor industry. Above all, the American. Historical crisis. The Historical crisis that Intel is going without resolving. And his new CEO, Lip-bu Tanalready I recognized A few weeks ago, “twenty or thirty years ago we were leaders. Now the world has changed. We are not among the ten main semiconductor companies.” The mass layoffs and the decision of Bet everything to lithography 18a –No 20th node– They raised a complicated future for the company, which needs maneuvering margin. He has just obtained it, but we don’t know at what price. Or maybe yes. The agreement. According to indicate in IntelUnited States will invest 8,900 million dollars in company shares, and that adds to the 2.2 billion dollars that the US government paid to the company as part of the Chips and Science Acta federal program that was approved in 2022 and is intended to invest billions of dollars to relive the country’s semiconductor industry. Intel was too big to fall. He Moment of weakness It is still worrying, but there have been two recent “bailouts.” The first, by the Investment of 2 billion dollars of softbank In the company. The second, much more important, the one that has just signed the US government with the purchase of 10% of Intel for 8,900 million dollars. This measure is especially striking for several reasons. For a start, is the first time that the US government intervenes a company since the rescue of the car industry was produced during the 2008 crisis. But there are more implications. Potential loss of autonomy. The agreement is only economic and there will be no official representation of the US government in the Board of Directors of Intel. However, political pressure will now be seen without a doubt increased, and each business decision of Lip-Bu Tan and its team will be seen through a different prism: there is public money at stake. Desperate times, desperate measures? Another perspectives from which this agreement can be contemplated is that of despair. Accepting this governmental “rescue” can be seen as a clear indication that Intel was against the ropes and there was no escape without any movement of this type. For Lip-Bu this can represent a problem for confidence in his leadership now that he has just taken command, and in fact the American senator Tom Cotton He accused him to invest in 600 Chinese companies. President Trump He came to ask for his resignation In Truth Social and then end up meeting him and congratulating him for its management. A logical agreement for Trump’s roadmap. The US president began his mandate with the clear intention of centralize semiconductor production to the maximum and electronics products. This protectionism is closely linked to this decision, and allows to protect Intel in addition to mitigating the dependence of Taiwan and the Chips import and technology From China. The Secretary of Commerce, Howard Lutnick, Indian That the agreement is especially beneficial for the US government, pointing out that they were basically giving money to companies through subsidies, but here what the US achieves is to raise that subsidy as an investment. It is not “lost” money. It is not clear that since the money comes from the ACT chips, the US government is allowed to end up obtaining benefits of such “investment.” Favoritism. This politicization of the semiconductor business could end up causing uncomfortable alliances and distorting competition. Now that all kinds of government agencies may have much more inclination to buy Intel chips in the future, while direct competitors such as Apple, AMD, NVIDIA or Qualcomm are harmed before a landscape of government favoritism. Intel, we insist, perhaps it was too big and iconic to drop it, but this intervention raises a change in the rules of the game that affects both Intel and its national competitors and, of course, foreigners.

Depseek has just launched something that will bitter the day and the US chips companies: it is called Depseek-V3.1

by

There was a day when Depseek surprised half the world by demonstrating that you could go far with less. Today returns with V3.1 And a message that does not go unnoticed: the model has prepared for the next Chinese chip batch. We are not talking about an automatic market overturn, but about a concrete bet that points in an awkward direction for Nvidia and company. If that technical tune with the Chinese hardware It translates into performance, conversation about who feeds AI in China is going to sound very different. According to the company’s own noteV3.1 opens a hybrid inference in the purest style GPT-5: the same system with two routes, Think (deep reasoning) and Non-Think (Quick response), Sygons from your website and app. The formulation is clear: “Hybrid Inference: Think & Non-Think, a model, two models.” The company also underlines that the version Think “Reach answers in less time” than your predecessor. That is, not only do pesos change, the inference modes that are already in service also change. The phrase that frames everything: an FP8 “thought for national chips” In a comment set in his latest publication in Wechat, Depseek writes: “EU8M0 FP8 is for the next generation of national chips.” That is the point that tense the rope: it suggests that the company has adjusted the data format, apparently a FP8 which label as EU8M0, to the next wave of Chinese processors. Bloomberg andReuters collect that message And they synthesize it: v3.1 is “personalized to function with next -generation AI chips Chinese. ”In other words, optimization oriented to the local ecosystem. The original comment in Chino (left) and its Spanish translation with Google Translate (right) FP8 is an 8 -bit format that weighs half that FP16/BF16. With native support, it allows more yield per cycle and less memory, provided that the climb is well calibrated. In the official Model Card of Hugging Face It is read that Depseek-V3.1 “has trained using the EU8M0 FP8 scale” format, which indicates that it is not only a packaging of weights, but that training and execution have been expressly adapted to that precision. The delicate part, and it is convenient to be prudent, is that everything points to a chips remittance that will be displayed in the future, since they can take advantage of this scheme natively. So is this bad news for Nvidia? The data of the fiscal year that expired on January 26 indicates that China represented approximately 13% of the company’s revenues led by Jensen Huang. If part of the computation of AI in China Classic duo muta NVIDIA GPU + CUDA ECOSYSTEM To domestic solutions that work with the UE8M0 FP8 format and give good results (presumably chips ascend of Huawei), the demand for Western solutions could be eroded over time. China meant about 13% of Nvidia’s income in the last fiscal year All this happens on the US export controls board: restrictions that sought to stop China’s access to leading chips and that have also accelerated their commitment to self -sufficiency. This year the Trump Administration rehabilitated with conditions the export of H20a chip cut for China. Since then, the state of the H20 has been oscillating: among permits, Chinese regulatory pressures and Nvidia plans to present Blackwell -based alternatives. The background message is that the framework is political and changing, and any route that allows China to depend less on these windows becomes strategic value. You have to remember another fact that helps to calibrate expectations. According to Financial TimesDeepseek tried to train his future R2 model with Huawei chips ascend to official instances and found persistent technical problems. He ended up returning to Nvidia for training, while he was still working on the Compatibility for inference. That episode does not invalidate the current strategy, but puts the bar: to completely migrate its processes is not simple, it requires, among other things, months of engineering. V3.1, therefore, it must be read as iteration. Now the company states that it has prepared its model for the next Chinese chips. Matherena models scores And here we have another interesting fact. Matharenaa platform linked to Zurich Federal Polytechnic School which evaluates models in real and recent mathematical competitions, places GPT-5 as a leader, with 90% in final response tests, already deepseek-v3.1 (Think) something behind although among the best models of the moment. This helps to locate the context: V3.1 Compete above.

His bet is called KF-21, and is almost ready for real action

by

The KF-21 has not been designed to impress Washington, or to compete with the F-35 in rankiness. It has been designed for something simpler and more ambitious at the same time: that South Korea does not depend on anyone when you need a combat plane. The country is called Boramae, Hugon Hunterand want it to be the axis of your Air defense until 2032. It is not just a new generation hunting: it is a symbol. And everything indicates that it will also be a notice for its neighbors. When South Korea wanted to access F-35 technologies to integrate them into their future hunt, he ran into a resounding negative. The United States rejected Transfer key systems such as Radar Aesa, the electrooptic aiming system (Eots), IRS and the radiofrequency disturbance of electronic warfare. That episode was decisive. Seoul assumed that, if I wanted to have control, I would have to build from scratch. Thus was born the KF-21. With him, Korea does not break with his western partners, but marks a clear line: there can be no real sovereignty if the most sensitive technology continues to depend on third parties. The South Korean jump towards autonomy in defense For Seoul, the KF-21 not only responds to a desire for industrial independence. It also responds to a strategic need. Tensions with North Korea are cyclical, but constant. China continues to rearm. And Japan already works with the United Kingdom and Italy at the GCAPthe future sixth generation hunting that should fly around 2035. South Korea does not want to be left behind. According to DAPA, the agency in charge of the projectthe KF-21 will first replace the F-4 and F-5, and then apart from the F-16. Having your own plane is defense, but also positioning. According to the governmentSouth Korea became the eighth country to get a supersonic hunt for its own development to carry out a test flight. The first prototype of the KF-21 was presented in April 2021. Three months later, On July 19, 2022, he first took off from the Sacheon base. Since then, the six planned prototypes are already flying and have exceeded milestones such as the first supersonic flight (January 2023) and the first real tests with meteor missiles (May 8, 2024) and Iris-T (May 17, 2024), according to Dapa and Diehl Defense. Deliveries to the Air Force will begin in 2026. One of the KF-21 keys is what it has inside. The aesa radar that equips is not imported: It has been developed in Korea by Hanwha Systems and the Defense Development Agency. The same goes for much of the plane, mission systems and sensors. The objective, According to Kaiis to reach a rate of 65% nationalization In serial production. The engine may not be yours yet, but what is seen in the cabin and radar is. Developing KF-21 has not been cheap. According to Dapa figuresthe initial development budget was set at 8.8 billion Wones, which is equivalent to about 5.4 billion euros. The cast was clear: 60% is contributed by the government, 20% KAI and local industrial partners, and the remaining 20% initially agreed with Indonesia. South Korea has opted for a gradual strategy, with blocking in blocks and a progressive nationalization of components. He does not seek to have everything from day one, but control each phase of the process. Indonesian participation has been one of the most unstable points of the program. Initially signed to finance 20% of development, But he stopped paying years later. After years of tension, In 2025 a new framework was agreed: Your contribution will be 600,000 million wones, about 415 million euros then. The agreement maintains some technological transfer and access to production for the Indonesian Air Force. South Korea will assume the rest. The project advances with or without them, but not without costs. The engine is today the main external dependence of the KF-21. Use General Electric F414, The same that propels F/A-18 Super HornetAssembled under license by Hanwha Aerospace in South Korea. Although that allows some logistics control, the supply is still tied to US authorizations. The South Korean industry already works in its own enginebut it is estimated that it will not be ready before the next decade. Meanwhile, any export plan of the KF-21 will continue to be subject to the ITAR regulations. It is the last piece that Korea still does not control. The KF-21 has been designed with export in mind. South Korea has already shown that you can sell light fighters such as FA-50. Now he wants to repeat the movement in a higher range. Philippines and Poland are among the possible KF-21 clients, And Egypt appears in the media radar, although without official confirmation. The only real limit is the American seal which still weighs on certain components, at least until there are motor and other components. Although the program advances according to the calendar, not everything is resolved. The first units that will be delivered from 2026 will only have Air-Aire capabilities. Air-Tierra weapons integration is scheduled for 2027, As confirmed by the Acquisition Programs Council. Nor are real operating costs, or their behavior in continued service. The South Korean Air Force will assume that risk in the first person. The KF-21 has demonstrated a lot in a short time, but the definitive test has not yet passed: that of daily use. It is not yet in service, but the KF-21 has already fulfilled part of its mission: to demonstrate that South Korea does not need to choose between being a client or staying out. It can be manufacturer. And it can be seriously. What comes later – exports, improvements, additional blocks – will depend on the operational result and the international context. But the key step has already occurred. Now it’s time to wait to know the results.

We had been talking about the most lethal Russian weapon that seemed like Ukraine fallen asleep. His answer is called Liutyi

by

If drones have become The protagonists From the Ukraine War, the model that has marked Russia’s offensive offers no doubts: The Shaheds of Iranian origin, then converted into different versions assembled in MoscowThey are the basis of Russia’s offensives. And in Ukraine? There they also have been perfecting a device that has become key to attacks on critical objectives of the enemy. The strategic weapon of Ukraine. Yes, kyiv, aware of its lower industrial and resources capacity, has opted for a different approach: Use surgical attacks with drones of own manufacture against strategic objectives deeply located in Russian territory. The jewel of this strategy is the AN-196 Liutyia lodging ammunition system designed to achieve precision Critical facilities of military logistics, oil refineries, air bases and essential industrial centers for the Russian war effort. Development and technical characteristics. Dron Liutyi began to develop In 2022 by Antonov in collaboration with Ukroboronpromconceived as a long -range unidirectional attack vehicle. The first version weighed between 250 and 300 kilosmeasured 4.4 meters long with a wingspan of 6.7, and was promoted with a gasoline engine that moved a rear propeller. It incorporated a V -tail design to improve stability and aerodynamics, and initially carried 50 kilos of explosives at a range of 1,000 km. The most recent versions have practically doubled their benefits: increased load capacity to 75 kilos and a range of up to 2,000 km, for an estimated unit cost In 200,000 dollarsfigure greater than that of the Shahed but still much lower than that of a cruise missile. And more. Your navigation combines inertial and satellite systems In the initial phase, while in the final approach it resorts to artificial vision to execute evasive trajectories, dodge defenses and hit with precision. First operational deployments. The use of Liutyi was made visible in 2024 With deep attacks in Russian territory. In January, an attack against An oil tank In St. Petersburg, he was attributed to drone, as was the March attack against the Ryazan refinery that caused a great fire. In June, the Mozdok Air Basein Norte Osetia, which houses bombers Tu-22m3 and fighters MIG-31it was also beaten. These incidents showed that Ukraine was in a position to project power hundreds of kilometers from the front line. Expansion of your role. The improved Liutyi versions began to be used massively this year. On March 13, an attack reached a Gas pipeline control center In Sátov, affecting the Russian energy sector. In April, several waves of Liutyi impacted the base of the 112.ª missile brigade in Shuya, destroying facilities of command and barracks. In July, two Liutyi penetrated 1,400 kilometers to Izhevsk, where They hit the Kupol plantproducer of anti -aircraft Tor-m and Harpiya drones, causing significant damage. That same month, different videos They documented attacks against objectives in the Leningrad region, in the city of Pensa and at the Sochi airport, where a fuel tank was reached. These blows have had a double effect: disorganizing Russian logistics and forcing Kremlin to allocate resources to the defense of the rear. International response. Despite his successes, Ukraine faces the disadvantage of not being able to manufacture Liutyi in quantities comparable to Shahed’s mass production by Russia. External support is, therefore, crucial: Germany has committed investments to produce 500 additional unitswhich will allow the pace of operations. Thus, the Ukrainian strategy will continue based on the selective use of these drones, with emphasis on precision attacks and not saturation. To maintain its effectiveness, Liutyi must adapt continuously, incorporating advances in artificial intelligence, computer vision and electronic countermeasures resistance. Strategic role in war. In short, although less known than The ShahedLiutyi has become a symbol of Ukrainian capacity to innovate and hit in depth, eroding the perception of security in the interior of Russia. Their attacks have affected energy facilities, refineries, industrial plants and air bases, weakening critical infrastructures and forcing Moscow to disperse their defenses. In this way, the drone not only compensates (in part) the Ukrainian material inferiority in front of the Russian military industry, but also opens a new psychological and strategic front by demonstrating that no Russian area is out of reach. Thus, everything indicates that its role will continue to expand in the coming months, consolidating itself as one of the key weapons in the Strategy of Resistance and Counteroffensive of Ukraine.

It is called 815a and its power lies in the place from which you can watch

by

That China is determined to intensify its operations Navales is out of any doubt. Not only is it raising a fleet of aircraft carrier that you have never had, its operations with Combined exercises in nearby waters (And not so much) They attest to that explicit demonstration of their global ambition. Now, in addition, you have to add the last demonstration of Beijing force: a gigantic detective. The new era of naval espionage. Yes, spy ships Type 815a They have become a fundamental piece of Chinese maritime strategy. His recurring presence in disputed waters and in international exercises reflects Beijing’s determination to project power and collect strategic intelligence persistently. In fact, the recent case of tianwangxingintercepted by the Philippines coast guard within the exclusive economic zone of Manila while escorting a destroyer and a Chinese coast guard, symbolizes this new stage of aggressive surveillance. And more. The remarkable thing is that the operation coincided with the Aerreo Exercise Cope Thunderin which the United States first deployed F-35 furtive fighters In the Philippines, which reveals how the Chinese Navy guides its naval espionage to capture in real time the military capabilities of Washington and its allies in the Pacific. Expanding float. The origin of 815a dates back to late ninetiesWhen China sought technological independence in naval intelligence. The first ship, Beijixingwas the first totally designed and built in the country, opening a series that since 2010 has multiplied with the arrival of more advanced variants. With dimensions of 130 meters of length and 6,000 tons of displacement, these boats count With diesel engines of great autonomy capable of sustaining prolonged missions thousands of kilometers from its bases. By incorporating furtive techniques into the helmet, closed masts and absorbent coatings, they manage to reduce their radar firm. The Type 815a One More Thing. However, the distinctive feature of the class are its bulky radomes, which protect electronic intelligence systems (ELINT), of communications (Comint) and radars capable of capturing and analyzing signals in wide ranges of the electromagnetic spectrum. Detection capabilities. What really makes these ships A complete map of the adversary military environment. As? They can identify radar emissions of aircrafts and destroyers to more than 700 kilometersand even to 1,200 according to some reports, in addition to tracking 1,500 kilometers. The information collected is transmitted in real time through connected redundant satellite links to the Beidou systemallowing immediate integration with anti -men’s ballistic missiles like DF-26 or the Hypersonic YJ-21. In this way, the presence of a single 815a in the vicinity of a multinational naval exercise is equivalent to placing a whole fleet under the sight of Chinese attack systems. From sea to space. Plus: The new recognition ship Liaowang-1 He has taken this doctrine even further. Its sensors, with detection capacity of up to 6,000 kilometers and satellite monitoring in geostationary orbit, expand the Chinese surveillance field to space. With six poachers endowed with multiband sensors, neural networks algorithms to classify targets with 95% precision Even under electromagnetic interference, and Aesa radar modules based on gallium nitride (ten times more powerful than previous generations), the Liaowang-1 constitutes a jump that S sItúa China at advantage against US equivalents such as Howard O. Lorenzen. This not only strengthens Chinese naval deterrence, but opens a spectrum of early control and warning operations that transcends the maritime surface. Surveillance strategy. The constant practice of sending An 815a to monitor international maneuvers (from RIMPAC In Hawaii Even Talisman Sabre In Australia) it has become a routine tactic. The mere entry of one of these ships in the area of an exercise Activate the network Chinese satellite, which transforms a routine deployment into a real -time attack simulation. For United States allies, this presence means having to Limit radar emissions and communications, which reduces the effectiveness of joint maneuvers. In other words: in an open conflict scenario, the shadow of an 815a would imply that the position of each enemy ship would already be incorporated in the Chinese missile guidance calculations. Strategic implications. Beyond electronic war and classic naval espionage, 815a constitutes A central node in the concept of Chinese multidominium warcapable of linking the surface of the sea, airspace and terrestrial orbit. Its visibility, however, also represents a weakness, since its radomes make it an easily identifiable target. Analysts expect future variants incorporate antennas Conformal integrated into the helmet, increasing its stealth and reducing vulnerabilities. The inclusion of command systems based on artificial intelligence is also anticipated to coordinate swarms of drones and electronic attacks autonomously, expanding the radius of action of Chinese intelligence beyond physical. Silent threat. In short, the 815a shipswith its low profile in terms of weapons and its enormous reach in matters of intelligence, they embody the new paradigm of the Naval War: it is not the visible fire power that defines superiority, but the ability to collectprocess and exploit data in real time to guide long -range weapons. China has turned these platforms into strategic multipliers that guarantee that any American attack group in the Indo-Pacific is under constant observation and, potentially, under direct threat of its missile arsenal. In them, Beijing’s transition is condensed from being a regional vigilant power to Aspiring superpower With the ability to control the sea, air and outer space.
