North Korea’s new frigate looked like a 21st century ship. Until you look at the sides and discover their solution against drones

In October 2000, the US destroyer USS Cole suffered an attack with a small boat loaded with explosives while refueling in Yemen. The attack led the United States Navy to reinforce the use of machine guns heavy weapons to protect their ships against short-range threats, a decision that is once again gaining prominence today for a very different reason: drones. A frigate with great aspirations. The new Kang Kon It represents North Korea’s biggest leap in surface ships. Although Pyongyang classifies it as a destroyer, its displacement about 5,000 tons places it closer to a frigate by international standards. On paper, the ship brings together almost everything you would expect from a modern design: dozens of vertical launch cells for missiles, a main gun, point defense systems, electronic warfare and cruise missiles capable of carrying nuclear weapons. The most striking detail. However, the broadcast images After the latest tests of the ship they have diverted attention to a much more unexpected element. At least a dozen heavy machine guns can be seen along one of its sides. 14.5 millimeter KPVdistributed between remote-controlled double mounts and other positions integrated into the superstructure. The scene turns out almost disconcerting: a frigate that seems designed for the 21st century, at the same time uses a solution reminiscent of the great naval combats of the past. The Kang Kon was seen firing its machine guns during a demonstration last week The war in Ukraine explains it. Although at first glance it may seem like an extravagance, the logic behind this configuration responds to a very current threat. The drone proliferation aerial and unmanned vessels has forced many navies to reinforce the short-range defense of their ships with additional small-caliber weapons. Russia has been incorporating additional machine guns, remote weapons stations and even improvised protection structures for years to try to stop drone attacks, an experience that North Korea has been able to observe very closely thanks to their growing cooperation military with Moscow. A weapon with more than half a century of history. Plus: KPVs are not exactly a modern system either. Designed by the Soviet Union At the end of World War II, these machine guns continue to be used in many countries due to their power and range against light targets. Your ammunition 14.5 millimeters It can destroy drones, speedboats or lightly armored vehicles, which explains why a weapon conceived decades ago is once again gaining prominence in a scenario dominated by much more recent threats. Survival remains the great unknown. The abundant Kang Kon weaponry It does not clear up doubts about their ability to survive in a high-intensity conflict. The TWZ analysts They consider that a ship of these characteristics would be one of the first objectives of any adversary and that North Korea will hardly be able to build enough units to give depth to its fleet. The reason? Even if it incorporates technologies of Russian origin, converting a missile-laden platform into a truly resilient ship requires much more complex sensors, training, coordination and operational doctrine than adding new weapons on deck. A ship that reflects how naval warfare is changing. The Kang Kon It leaves a striking image because it summarizes one of the great paradoxes of current conflicts. Long-range missiles, radars and electronic warfare represent the most advanced naval technology, but defense against drones has brought back the spotlight to surprisingly simple solutions. that one of the most modern frigates North Korea’s proud display of a heavy machine gun battery speaks volumes about how the war in Ukraine is redefining design priorities in even the newest warships.

It has 12 sides and is 351 meters high

Although in recent times Asia and the Middle East have emerged as the new locations for skyscrapers (in fact, China is the place in the world where there are the most buildings that caress the sky), the place par excellence for skyscrapers has always been North America. Cities like New York or Chicago and legendary buildings like the Empire State, One World Trade Center or the Central Park Tower set the pace of a competition that once seemed reserved for American cities. But North America is not just the United States and the constructions of Torres Obispado in Monterrey or the imminent Tower Rise They show that their neighbors also know how to build skyscrapers very well. In this context comes the Pinnacle SkyTower in Toronto, a skyscraper that, although it is not the tallest in meters nor does it have the most spectacular silhouette, is going to mark a milestone: be the residential building with the most floors in all of North America, as well as the tallest skyscraper in Canada. The skyscraper with 12 faces. The Pinnacle SkyTower that is being built in Toronto reaches a total height of 351.85 meters in its 106 floors. It will house 958 luxury homes, the new Le Méridien Toronto hotel, some 7,400 square meters of common areas and crowning it all, a restaurant with panoramic views on the top floor, such as explains the design studio Hariri Pontarini Architects. The forecast suggests that future residents They will be able to move in starting in autumn 2026, although the complete delivery of the set will be in 2027. One of the aspects that attracts the most attention is its dodecagon shape. As Jodi Buck, partner of the architecture studio, details, this geometry seeks a balance between architecture and functionality, that is, it allows the construction of a more slender structure, opens views in various directions and something essential in buildings of this size: it better distributes the wind load on the façade. The upper floors progressively reduce until the tower ends in a striking pointed crown, which makes the SkyTower an unmistakable silhouette on the Toronto skyline. Why it is important. To begin with, because The SkyTower breaks records: it will be the building with the highest number of floors in a residential building in North America. But there is a trick: it is not the tallest in meters, that title is still held by the Central Park Tower in New York, but it is the one with the most floors. This implies a design decision: favor the construction of more homes in a commitment to greater residential density per meter built. At the urban level, with this building Canada is put on the map as a country capable of competing in this segment of super-high-rise skyscrapers, historically dominated by American and Asian cities. In fact and how points out New Atlasis one of the first Canadian skyscrapers to exceed 300 meters in actual building height. Curiously, setting the record was not initially in the project: with construction already underway, Pinnacle International made it possible because submitted an application to increase the height of the ceilings on some floors and convert mechanical space into habitable space. Projection of the new and exclusive urban development of Toronto. One Yonge Toronto Context. The SkyTower is the jewel in the crown of the Pinnacle One Yongea mixed-use development plan that is transforming the grounds of the former Toronto Star building into one of the city’s largest urban complexes, connecting the tower to a future public park next to Lake Ontario and the financial district. The complete set is formed by six towers of between 22 and 106 floors that will house 2,500 homes, 93,000 square meters of offices, 7,400 square meters of shops, a community center of 4,600 square meters with a swimming pool and gym and a one-hectare public park. The first tower in the complex was the Prestige: it has 65 floors and was completed in 2022. The Pinnacle SkyTower is another example of the trend of super-tall towers that combine homes with hotels, a model widespread in Asia that North America is adopting in response to the housing need and the scarcity of land in central areas. Without going any further, Toronto has several similar projects under construction. Yes, but. As we mentioned above, SkyTower does not win in meters but in floors: the Central Park Tower in New York surpasses it in absolute height thanks to its higher internal ceilings and we have the antenna, the First Canadian Place in Toronto equals it (although it is true that this does not count in official rankings). On the other hand, and although it obviously increases the housing available in the Canadian city, we are talking about a building with 958 luxury homes with prices from 800,000 Canadian dollars and a five-star hotel. With that budget, it is difficult to resolve the problem of access to housing for its citizens. It is new housing, yes, but with prices within the reach of few.

Everyone thinks that the Great Guiza Pyramid in Egypt has four sides. From space you look very different

A team of Japan researchers scanned under the sand surface in a “blank area” of Giza’s western cemetery next to the Great Keops pyramid. Had found something surprising: an old Egyptian structure in underground. That finding is still involved in the mystery, because it was dwarfed with Another study that he had discovered something fascinating: the great Guiza pyramid does not have four sides, and that explained His longevity. A wonder with trick. For millennia, the Great Guiza Pyramid It has been celebrated as the epitome of the perfect geometry: four imposing triangular faces converging in a majestic apex. However, an unsuspected structural detail had remained hidden with the naked eye: the pyramid It does not have four sides, but eight. Chronology. We are not crazy. The revelationconfirmed by air observations and Modern researchpoints to a concavity in the center of each face, one that is invisible from land, but detectable low certain conditions of lighting or from the sky/space. The first to realize something was the British pilot P. Groves In 1926, when captured an image Air that revealed a subtle but decisive geometric truth. Each of the four apparent sides of the pyramid has a central cleft from the base to the cusp, which turns its plant into a figure eight sidesNot in a home run. Already in 1940, the Egyptologist Flinders Petrieby analyzing historical illustrations, he noticed A hollow line along each face of the pyramid. Decades later, experts like IES Edwards And more recently the Mathematician Akio Kato They supported this hypothesis in their work, noting that the stone blocks were arranged with a Mild inclination towards the center, creating a subtle and almost imperceptible longitudinal depression. Kato described the great pyramid not as a square pyramid, but as a Concava octagonal pyramid. One of the first images where depression was appreciated (taken by groves) An engineering feat. The curious thing about history is that, far from being an aesthetic anomaly, these clefts aim to fulfill a Structural function vital. According to Kato’s study, the inclined layers next to a reinforced base allow the pyramid nucleus to Compacte and strengthen Over time, thus resisting gravitational compression, earthquakes and storms, even after having faced more than 500 episodes of heavy rains in 4,500 years. In other words: this characteristic would have been key to ensuring the long -term stability of a colossal size structure exposed to extreme conditions, and possibly was not a mere side effect of construction, but a sophisticated architectural strategy. Between intention and accident. However, not everything in the Great Pyramid responds to the master plan of an infallible civilization. Throughout their runners and sealed cameras, abandoned spaces have been found that could Unstable result During construction, which leaves open the possibility that the unique concavity has been, in part, the result of improvised adjustments rather than a completely premeditated design. No doubt, ambiguity does not remain merit to the ancient builders, but underline their pragmatism: modify the course when the conditions demanded it, and incorporate the accidental as part of the lasting structure. What the geometry hides. In short, that its mathematical truth has remained hidden with the naked eye for millennia highlights an essential lesson on The great pyramid: Secrets continues to reveal despite his universal fame. What seemed to be an elementary geometric figure becomes, under a new look from the air, a sample of invisible complexity, and technical decisions so advanced that today they still baffle us. The revelation of your Concava octagonal form Not only challenges our preconceived notions, but reaffirms the fascination that always accompanies Guiza, a pyramid that, as far as we know (and we do not rule out new surprises), is a unique geometric rarity in its species.
