There is an F-35 stranded in Japan and nobody manages to start it

by

In the middle of July a news began To “get ball” in the United States and the United Kingdom. A brand new F-35b by Lockheed Martin and belonging to the British Navy was stranded more than a month In India. Since then until now, the almighty American company has happened to the problems: Negative of Spain For the purchase of a lot of fighters, the doubts from other countries And finally, a Second F-35 stranded. The problem is that there continues, without leaving Japan. An emergency detour. A F-35B of the United Kingdom, deployed aboard the aircraft carrier HMS Prince of Wales within the framework of the Highmast operation, Continue stranded In Japan after having forced an emergency landing at Kagoshima airport on August 10 due to a technical failure in flight. The device was transferred to a shooting street and no injuries were reported, although six commercial flights They suffered delays. Engineers of the Royal Navy and the Royal Air Force have already inspected it and confirmed that it is waiting for spare parts to be repaired, reviving doubts about the fragility of the global supply chain of the supplies of the supplies of the supply of F-35 programdespite the fact that both the body of American Marines and Japan operate the same model in the region. A problem history. As we said at the beginning, the episode occurs shortly after another detour, This time in Indiawhere a second F-35b British was stranded for more than a month, and adds to the long list of incidents associated with the furtive plane. Although the British Ministry of Defense insists that both failures They are not related and that these types of situations are part of the routine of naval operations (where it is often safer to take land in nearby airfields than to try a risky apontaje on the aircraft carrier), the truth is that the coincidence has intensified the Public and political scrutiny About the program. The memory of 2021 accidentwhen an F-35B of the HMS Queen Elizabeth crashed in the Mediterranean for the obstruction of an air intake, it is still weighing on the reputation of the hunt. The operation and strategic role. The Highmast operation It represents one of the most important deployments of British naval aviation in the Indo-Pacific, with 18 F-35b embarked, from RAF squadrones and Royal Navy, to which at least one device of the US Marines body is added. The campaign already included maneuvers in Australian waters during the TALISMAN EXERCISE SABREand later joint exercises in Japan and South Korea under the name of Hightower. One of the milestones was the first operation of British fighters from a Japanese ship, the Kagaadapted to receive Stovl aircraft such as the F-35B, a symbolic gesture of the growing naval cooperation in the region against China. A “of all” hunt. For Lockheed Martin, the story puts them again in the Diana in a month of August complicated where the news has happened with the hunt as the protagonist. The funny thing is that we talk about a combat plane that, being “made in USA”, is actually built under A multinational program. Yes, the F-35 Lightning II is actually the most international combat program in history, with more than 1,900 suppliers spread over a dozen countries. Conceived since its origin as a multirrol plane for the three branches of the country’s armed forces and for strategic allies, established association levels: The United Kingdom as the only partner of Level 1, Italy and Netherlands at level 2, and Australia, Canada, Denmark and Norway at level 3, to which Japan and Israel are added through special agreements. Most devices are assembled in Fort Worth (Texas), but there are assembly and verification centers in Cameri (Italy) and Nagoya (Japan), with production lines adapted to regional demand. The European contribution. The United Kingdom is the Major foreign taxpayerresponsible for about 15% of each plane and 10% of development costs. Companies such as Rolls-Royce (manufacturer of the F-35B lifting system) and Martin-Baker (ejectable seat supplier) complement the decisive participation of Bae Systemswhich produces rear fuselages, queues, electronic warfare systems, antennas and much of the mission software. Italy, through from Leonardonot only manufactures optical components, radios and motor parts, but also hosts the only European final assembly line. The Netherlands, With GKN FokkerThey produce flaperones, braking systems, electrical wiring and manage spare parts for more than 500 European fighters. The rest. Australia manufactures Vertical lines, actuating systems and more than 700 components in the state of Victoria, with more than 70 local companies involved. Norway provides air-air pylons and vertical edges, while Finland supplies front fuselage sections. Japan assembles its own F-35a in Nagoya and produces some pieces domestically, although it is not clear how many are exported. Israel, unique case, not only manufactures components valued at more than 2,000 million dollars (such as external wings, fuel deposits and electronic warfare systems), but also The F-35i Adir operatesthe only authorized version to be deeply modified, with plains, weapons and its own communications. Contractors in the USA. In the United States, Lockheed Martin coordinates and assembles airplanes, but the bulk of the content comes of associated giants. Northrop Grumman produces central fuselage, AN/APG-81 radar and communications systems, with a participation between 20 and 25% per device. RTX, through Pratt & Whitney, supplies the F135 engines, while Raytheon provides armament and advanced sensors. Other actors such as Honeywell, L3harris or Curtiss-Wright have key papers in specific systems. The great absent is Boeing, whose X-32 lost the contest in front of Lockheed X-35; Today its role is limited to minor work as a subcontractor, while concentrating its efforts in the F/A-18 Super Hornet, the F-15Ex and its F/A-XX future. Between symbolism and fragility. Back to the case in Japan, that two fifth generation fighters have been out of service during the same cruise does not constitute an operational disaster, but it does feed the Vulnerability perception in a program already controversial for their cost overruns, … Read more

Australia has analyzed teleworking since before pandemic. His conclusions disassemble the reasons for the return to the office

by

Although teleworking is no longer the preferred option by companies, or at least not their full -time variant, remote work continues to maintain much higher values that those who registered before pandemic. That shows that, in a way, teleworking does arrive to stay in Very specific contexts. Australia has been observing the real impact of teleworking for four years and consolidated data contradict old prejudices. “Working from home makes us happier,” The authors assure of a study by the University of Southern Australia, ciming a new more flexible and productive labor model. Time flexibility: the new office fruit. The Australian study is especially revealing because it began before the pandemic and the rise of teleworking and has been extended for four years, which leaves a much more defined photo of how remote work has impacted on the way of working and its consequences. According to the study, the possibility of choosing from where to work has allowed to improve both the mental and physical health of workers, although there is still a certain friction from corporate culture. According to A report of the International Labor Organization (OTI), the flexibility provided by teleworking is already equal to The emotional salary with which companies try to capture and retain the best employees, replacing other benefits. Most satisfied employees with their work. The data collected by the study reveal that before the pandemic, the Australian worker used about 4.5 hours per week only in displacements to the office. That time optimization It makes those who work from home enjoy “ten extra days of free time a year against those who go to the office”, dedicating 33% of that time to leisure, which implies “more opportunities to be physically active and less sedentary.” A factor that also highlighted the Academic Study which was carried out in Spain from the Lacaixa Foundation. According to the authors, these data “usually go hand in hand with worse mental health and with lower scores in the assessment of our own health.” Thanks to teleworking, employees have gained “hours of rest to sleep and, for example, breakfast more peacefully”, which helps reduce levels of template stress. In turn, this recovered time also has a reflection in healthier habits, such as home preparation or the increase in the consumption of fruits, vegetables and dairy. The result has been a more varied and healthy diet, with less dependence on ultraprocessed foods that require less preparation time. Positive whenever it is by choice. If something has shown us the experience of “forced” teleworking during the confinements of 2020 is that the teleworking It is not for everyone. Since this study allows to contrast the situation of employees before and after the massive arrival of teleworking, it also reveals how it affects that change of work model in workers The researchers found that the well -being and mental health They improved especially when teleworking was voluntarily chosen, while “when employees work from home for obligation, mental health and well -being tend to get worse.” Productivity in evidence. One of the main arguments of companies for the return to the office has been the alleged fall in productivity that was associated with teleworking. In this sense, researchers blame the problem more to an inability to assign tasks and New model management not in a direct casuistry of teleworking. “In many cases, managers who claim that teleworking reduces productivity responds more to a lack of management than a real performance problem,” says researchers in their conclusions. The conclusion after four years of monitoring is unequivocal: work performance and productivity seem to stay stable or, in most cases, improve when working from home. These results coincide With other research that They disconnect the decrease in productivity of the company with the teleworking. The distance does affect the cohesion of the equipment. Great corporations like Amazon wielded The argument of the cohesion of the equipment To impose The return to the office. In that sense, the study prepared by Australian researchers recognizes that “the connection with the classmates is difficult to reproduce at a distance,” admit those responsible for the study, and alert about the risk of loss of cohesion in the work teams. But, as has been demonstrated with some strategies back to the office, the problem can be mitigated by facilitating efficient communication channels. A Recent study Posted in the magazine Naturerevealed that this Team cohesion problem It currently persists with the hybrid day model, provided that consistent communication patterns are not established.

It is not that the war has entered its Mad Max phase, is that Ukraine is using the trucks we saw in the movie

by

In the month of June some began to arrive disturbing images From the war in Ukraine. We had previously seen how First and second World War were recognized in Some practicesbut the last was radical: waves offensive of Russian troops on two wheels, in motorcycles as a main tool to move towards the Ukrainian lines, in an attempt to avoid the destruction of their armored Modern to the power of drones. To that phase He has followed another almost traced to Miller’s movie. An improvised armor. Yes, the war in Ukraine has turned the battlefields into stages that remind of Mad Max universewith military vehicles covered by improvised shields seeking to resist the scourge of explosive drones. A recent image Taken in Kostiantynyaivka, north of Donetsk, showed a Humvee American used by Ukraine surrounded by a huge metal cage with networks and sticks protruding from its structure, an extreme example of solutions of fortune That both Russians and Ukrainians develop to try to protect themselves from an increasingly lethal enemy: the small drones that, with costs of just a few hundred dollars, are capable of destroying armor of millions. Origin and evolution. These protective screens, popularly known as “Cope Cages”began to be seen months ago, when the proliferation of drones transformed the land war. Initially they were installed only in combat cars and armored vehicles, but soon They spread to a wide range of systems. Your designs They vary greatly: Some structures are crude and heavy, others are better planned, incorporating metal cages, steel plates, chains, skewers, camouflage networks and even reactive armor to reinforce the most vulnerable areas. In the Russian case, some tanks have become completely coveredwhat has earned them the nickname “Tortuga tanks” for its resemblance to the shell of these animals. Industrial adaptation What began as improvisation of the soldiers themselves has evolved towards a more organized production. In fact, the Russian army already distributes official instructions for the construction of these cages, while in Ukraine several companies have developed versions adapted to different models, since T-64 and T-72 tanks of Soviet origin to the Abrams and Bradley supplied by the United States, even through Patriot antiacere systems. Despite this, the real effectiveness of these devices is the object of debate. The reason? Although they can offer some protection against FPV drones and some anti -tank weapons, Its weight and volume They usually hinder mobility and vehicle operations. The omnipresent drone. It We have counted many times. He drone boom low cost, used massively by both sides, has consolidated its role as asymmetric factor Decisive: They are able to neutralize high -value vehicles or eliminate entire crews with a minimum investment. The proliferation of this type of weapons has forced the last resort defenses as These “Cope Cages”but it has also promoted the development of more sophisticated technological measures. Electronic countermeasures. Both Ukraine and Russia resort to extensively to The electronic warblocking communications between operators and drones or interfering with your systems GPS navigation. In response to this, new generations of drones resistant to these techniques have emerged, such as connection models by optical fiberthat maintain a direct physical link with the operator and leave behind cable kilometers in the field. Outside, drones endowed of artificial intelligence They begin to be used more frequently, capable of completing their missions even if the connection is interrupted. Race between attack and defense. If you also want, the image of vehicles covered by improvised cages is the visible materialization of the New war dynamics In Ukraine: a constant career between the offensive capacity of cheap drones and the defensive creativity of soldiers and engineers. Although, as we said, some of these shields offer limited protection, their expansion reflects the urgency with which both armies try to adapt to an environment where the main threat does not always come from a long -range missile, but from a small artisanal drone that, thrown by an operator kilometers away, can decide the fate of a combat car that costs a fortune.

block everything to protect the football business

by

It seemed inevitable, and so it has been: football has returned, and with it, LaLiga IPS blocks in Spain. On Friday, the 2025/26 season began, and since then numerous users have been able to verify how those indiscriminate and massive blockages of IPS have also started. The nightmare does not seem to have a solution in sight. The League returns, the blockages return. The beginning of the season last Friday led the beginning of the IPS mass blocks. The first game, held on Friday at 7:00 p.m. It will start To show the message “HTTP 451 – File unavailable for legal resons” on various websites. Blockages, as they point out In Bandanchathey have continued producing throughout the weekend, but in fact they have intensified. Blackhole: We don’t even know what happens. Normally when the operators followed LaLiga’s “orders” when blocking IPS offered some type of message like that to inform users that a certain IP or website was not accessible. This weekend we have seen how Movistar went to the “Blackhole” type blocking in which traffic to that IP address is discarded without more, as if it fell into a “black hole.” There is no error message and the browser or apps are waiting until the “Timeout“And the waiting time is exhausted to respond to the request. The impression for the user is that this server simply does not exist. What operators have blocked. As indicated by various users affected in X, the blockages seem to have expanded: Movistar continues to perform them, but also both Masorange and Vodafone seem to have begun to block strictly. In Vodafone, they point out in Bandancha, a message is now showing that “for reasons outside Vodafone this website is not available.” Complaints everywhere. Several users HE They complained precisely from Those blockages of This operatoras happened in other cases in other competitors. Digi also seems have applied these blockages. After a critic of a user, the operator responded in X Explaining that these blockages are not “a decision of ours, but in compliance with a sentence in favor of LaLiga.” Others that until now did not seem to have applied these blockages, such as lowi, also seem to have initiated this type of actions According to affected users. Just for sinners. As it was happening since March, the impact of the blockages is difficult to measure, but There are many Users With business and legitimate websites on the Internet that have been affected by All sides. The attacks focus especially on CDN platforms how to see or cloudflarewhich make use of shared IPS: when operators block one of those IPS, they not only block the IPTV service that is pursued with that concrete IP, but hundreds and even thousands of websites that share that same IP address. LaLiga FUD. In recent days LaLiga had paid to publish editorial articles In several general media in addition to promoting The video “You have pirate football. They have you.” In these contents the objective was the same: to disseminate the message that those who use IPTV services of illegal streaming end up being potential victims of malware. To these statements were added others that pointed out that these types of activities could also serve to finance drug trafficking. The biter bit. At no time are evidence of this cause-effect relationship, and we are facing a clear chaos of the commercial strategy known as FUD (Fear, Uncertainty and Doubt, in Spanish fear, uncertainty and doubt) that disseminates negative, vague or bewoman information in order to harm a competitor. The truth is that anything has never been demonstrated in that regard, but LaLiga was fined a few months ago with a million euros by Collect biometric data Of the spectators without permission. The case is in the Constitutional. Both rootedcon and cloudflare have started various legal actions separately to try to stop the blockages, but for now those attempts They have not paid fruit. At this time these cases have been presented before the Constitutional Courtbut it is not expected that in the short term a resolution will occur. The blockages are going to be a nightmare, but they can dodge. The beginning of the season has therefore demonstrated what we all feared: that LaLiga will maintain (or intensify) those indiscriminate blocks of IPS. This first day has caused Fridays, Saturday, and Sunday, but there will also be left today and tomorrow, which means that predictably There will be more blockages these days. There is a way to avoid them: Use a VPN that allows us to have normal Internet access.

The divorce of China and Nvidia is a fact. The Xi Jinping government no longer recommends Chinese chips: it demands them

by

China is touring a path that has no going back. US sanctions and their allies prevent Chinese companies and public institutions that are dedicated to the development of models of artificial intelligence (AI) access the most advanced GPUs that design NVIDIA, AMD or brains, among other Western alignment companies. And in these circumstances the government led by Xi Jinping only has one option: minimize China’s dependence of technologies from abroad. In early October 2024 The administration arrived To the companies of Chinese a recommendation in which it asked them to use chips produced in China as much as possible. Ten months later, According to SCMPthis recommendation has become a demand. And it is that the Chinese government is already forcing data centers that belong to the State throughout the country to use at least 50% of Chinese integrated circuits on its servers. This scenario clearly favors a company: Huawei. Huawei has a unique opportunity, but also a monumental challenge Huawei invests more than $ 25,000 million annually in The development of your hardware for AIso presumably it will not take long to match the benefits of the GPUs produced by NVIDIA or AMD. His most ambitious proposal right now is the chip Ascend 910dwho seeks to overcome the performance of the GPU NVIDIA H100. However, this Chinese company has also recently presented its chip Ascend 920a solution that is clearly destined to occupy in the Chinese market the gaps that it will leave The H20 GPU of Nvidia. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC (Semiconductor manufacturing international corp). Nevertheless, Huawei faces a huge challenge that probably in the short term it will prevent you from satisfying the demand for chips for Ia from the Chinese market. In the middle of last June Jeffrey Kessler, the Undersecretary of Commerce for Industry and Security of the US Department of Commerce, He made this statement In Congress: “Our evaluation indicates that the production capacity of Huawei Ascend “Our evaluation indicates that the production capacity of Huawei Ascend by 2025 will be 200,000 units or less, and we foresee that the majority or all of that production will be delivered to companies within China.” This prediction about the production capacity of avant -garde chips for Huawei is sustained on an irrefutable fact: the mate of the integration technologies used by the Chinese manufacturer of SMIC semiconductors to produce the Huawei GPUs has a very wide margin of improvement. SMIC already has the ability to manufacture 6 Nm integrated circuits, and soon it can also produce 5 Nm semiconductors, but is limited by the performance of the deep ultraviolet lithography equipment (UVP) you have in your possession. It is meritorious that SMIC and HUAWEI engineers have managed to refine their integrated circuit manufacturing processes what is necessary to produce 5, 6 and 7 nm chips With ASML UVP teams, but a priori it is very unlikely that with these machines they will be able to go beyond the 3 Nm. And it is because the technique of Multiple patterningwhich is what they are using, imposes important limitations. A note: This strategy in broad strokes consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. His problem is that he usually has an upward impact on the cost of chips and the decline in production capacity. For Huawei it is a big problem not to have the necessary technology to produce avant -garde semiconductors comparable to those who manufacture Intel, TSMC or Samsung, so it is working on the development of its own team of extreme ultraviolet photolithography (UVE).

It will be the penultimate flight before his hopeful redesign

by

Starship’s path to orbit is not being a straight line, and the last months of the highest rocket in the world exemplify it bleeding. After lose four consecutive ships And a super heavy, Spacex has turned the failures into data with which to improve its design. Soon we will know if they have worked: there is only one week left for the tenth release. Green light for the tenth flight. The Federal Aviation Administration of the United States has closed the investigation Of the last incidents of Starship and authorized to Spacex the next flight, scheduled for Sunday, August 24. The Tenth Mission of Starship will prove the opening of the load gate and the redempted of an engine in the space. In addition, Spacex engineers have deliberately eliminated several tiles from the thermal shield of the ship to study their behavior during the reentry. A summer of investigations. Starship’s ninth flight, which took place on May 27, ended with the disintegration of both the Super Heavy Booster 14 and Starship 35. A report From August 15, Spacex explained the cause of both incidents: Booster 14, that flew for the second timehe failed during the sprainage maneuver after Spacex put his structural loads to the limit. With a 17 degree attack angle, the fuel transfer tube was not able to withstand aerodynamic forces, which caused an explosive mixture of liquid methane and oxygen. The Starship 35 reached the planned speed, but a methane leak in the front cone, caused by a defective diffuser in the pressurization system of the main tank, compromised the rest of the mission. The lack of pressure prevented the ship from opening the loading gate, and caused the automatic systems to abort the engine redempted in space. The ship disintegrated turning without control in a reentry agonizing. To finish Sink morals in Starbasein mid -June, a brutal explosion made the windows of neighbor Brownsville tremble. Starship 36, which should fly on flight 10, disintegrated during a fuel load, generating a small Geopolitical conflict with Mexico. Spacex attributes the disaster to a structural failure in a secondary nitrogen gas deposit, possibly for undetectable damage. Booster 16 and Starship 37 ready to fly. With the causes of the latest failures already identified, Spacex has redesigned the diffuser of the ship and implemented more strict inspection protocols for pressurized nitrogen deps. Two new prototypes, Booster 16 and Ship 37, are ready for Starship’s tenth flight with such ambitious objectives as ever. The Super Heavy propeller will not try to return to the tower, but will merit in the Gulf of Mexico, simulating a failure in one of its landing engines To check if a backup engine can take over, ending the maneuver with a “stationary flight” on the ocean with only two lit engines. For its part, the Starship ship will try to open its gate for the first time and display eight Starlink satellites models in a suborbital trajectory (which will be burned during the reentry). It will also try to redecend a Raptor engine in the emptiness of the space to exorbitate in a controlled way. The most striking thing is that it will fly with a significant number of deliberately absent thermal tiles to submit vulnerable areas to greater stress and try new materials, as metal with active cooling. The reentry is also designed to make the most the rear flaps of the ship at the point of maximum pressure. Starship’s third version on the way. There are only two Starship flights with the current design, which has meant great headaches for Spacex. The company finalizes the development of the starship 3, of which We have seen full renders and some components already manufactured, such as Your new grid fins and Its gigantic fuel tube. Although the new Super Heavy will wear three aerodynamic grilles instead of four, they are 50 % larger and more robust. This new design not only allows descents with higher attack angles (just the maneuver that caused the failure in flight 9), but fulfills a double function. The new fins incorporate an anchor point and are located below in the rocket to align with the arms of the launch tower, which will use them to lift and catch the propeller. Being lower, they also receive less heat from the starship engines during the separation of hot stages. Images | Spacex In Xataka | What Spacex has achieved with Starship is incredible.

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 believed that the “road of yellow tiles” was a private cinema. Until some divers descended to the depths

by

The idea of the yellow tile road was born with the novel The Wonderful Wizard of Oz by L. Frank Baum (1900), where a golden path is described that leads to the Emerald city and symbolizes the trip to personal fulfillment and discovery. In the famous adaptation to the 1939 cinema, that path became a visual icon thanks to the pioneering use of Technicolor: the bright yellow contrasted with the intense green of the city and the blue sky, marking the passage of Dorothy from Kansas’s gray routine to a fantasy world. It turns out that in marine depths we had Another way of tile. A geological finding. History dates back to 2022. During the Luʻuaaahikikekumu expeditiona scientific team aboard E/V Nautilus shipwhile exploring the chain of old submarine volcanoes of Liliʻuokalani Ridge, he ran into Rocking formation that remembered the mythical “road of yellow tiles” of the cinema. The curious structure, located at the top of the submarine nootka, within the National Marino Monument Papahānaumokuākeait turned out to be an example of ancient volcanic geology: rock fragments generated by high -energy eruptions, known as hyaloclastitethat have fractured uniformly due to repeated cycles of heating and cooling by successive eruptions. This pattern, similar to the cracked of the surface of a Brownie, has conferred the rock an appearance of perfectly aligned cobblestone. Origins and characteristics. Hialoclastite is formed when hot magma comes into contact with water, fragmenting into vitreous particles and accumulating in the seabed. Over time, these deposits are compacted and cemented, and, in cases like this, exposed to thermal changes that They produce rectilinear fissures. The found sector showed a stretch of “baked scab” dry to touch, An optical effect that surprised the team and generated jokes on the “road to the Atlantis.” The inspection with the nautilus robotic arm allowed to collect samples from Ferromanganésic scabs (rich in iron and manganese oxides) that covered the background, a resource of scientific and industrial interest. Importance of the mission. That was the First systematic exploration Of these submarine mountains, whose main objective is to understand the mysterious discontinuity that presents its alignment in the ocean bed. The finding of “road” joined other unique observations of the expedition, such as the filming of a strange agency nicknamed Headless Chickn Monsterstrengthening the idea that the area houses poorly documented biological and geological phenomena. Beyond the visual anecdote, the identification and study of these formations provides key information about the Submarine eruptive processes and the tectonic evolution of the region, opening the door to new discoveries in one of the most remote and protected areas of the planet. Scientific context. He find It was also framed in an international effort to map and understand the underwater structures that make up the hidden geography of the oceans. The formation of the “path” in Nootka Seamount Not only illustrates how volcanic activity can generate visually striking patterns, but also offers clues about the systems behavior submarine magmatic and its interaction with water in High energy environments. Plus: These studies are essential to improve underwater volcanism models, evaluate potential mineral resources and understand how these geological habitats influence deep marine biodiversity, a field in which each expedition reveals more unknowns than certainties.
