There has been a “flattening of the Earth” due to radars and missiles. And that makes fighters an easy target

The technological transformation in aerial combat has reached a point where legacy tactics of the 20th century have ceased to offer minimum guarantees of survival. For decades, pilots could rely on low-flying flight to penetrate hostile defenses: the curvature of the planet, terrain shadows, and background noise hid planes speeding below the radar horizon. That world has disappeared. The end of the old certainties. They remembered in a wide report in Insider that the modernization of sensors and missiles, the proliferation of electronic scanning radars advanced technology, the expansion of beyond-line-of-sight systems and permanent aerial surveillance have created an environment where safe altitudes no longer exist. The idea that terrain protects is, for contemporary air forces, a relic. Detection distances have gone from being a tactical inconvenience to becoming a a strategic condition that can span entire regions, redefining the way a country plans its defense and offense. The British example. counted Air Vice Marshal James Beck, RAF Director of Capabilities and Programmes, who when flying the fighter jet Tornado multipurpose In the early 2000s, it was still assumed that flying at very low altitude would allow a formation to penetrate enemy territory without being detected by their integrated missile defense systems. The military delved into the same theory, that new radar and missile technologies have caused a kind of “flattening of the earth” that puts even aircraft that fly at much greater risk. very low height. The Eurofighter Typhoon with the nose fairing removed, revealing its AESA Euroradar CAPTOR radar antenna The growth of prohibited areas. At this point, the strategies of anti-access and area denialpreviously limited to defensive belts around critical points, have expanded to configure operational spaces covering entire countries and that, in a few years, could extend over entire continents. For example, the rise of OTH radars capable of “seeing” behind the Earth’s curvature, the increase in the range of surface-to-air missiles or the multiplication of air platforms that continuously patrol have created defensive bubbles which entering becomes a high risk exercise even for advanced fleets. The aerial danger. This phenomenon not only changes the way deep strikes are planned, but also the priority structure in which air powers operate. Controlling the air stops being another objective and becomes the indispensable condition so that any other operation (hitting command nodes, degrading enemy logistics or destroying missile silos) is even conceivable. In recent conflicts, especially in the ukrainian warthe inability of either side to dominate the air It has generated a battlefield frozen by dense defenses, where planes fly low to the ground only to deliver ranged weaponry, and where deep penetration has disappeared from the equation. A Tornado of German forces Sensors and vulnerability. The evolution of AESA radarscapable of detecting multiple targets at high speed and adjusting their beam with electronic precision, combined with sensor expansion land, naval, air and space, has created a network that reduces the margin of error practically to zero. Surveillance systems no longer depend on a single layer or a single type of platform: they function as an eoverlapping weavereplicates and expands, maintaining continuous surveillance with immediate response capacity. In this context, even missiles have expanded its radius of action with a speed which exceeds the modernization capacity of many air forces. The consequence is an environment in which aircraft without reduced signature, expanded connectivity, and platform-level sensor fusion simply will not survive crossing the enemy threshold. New air capabilities. In it Insider report The British military delved into an idea: the acceleration of innovation forces to reconfigure both existing systems and the future architecture of the air forces. Modernizing command and control, integrating distributed sensors across multiple domains, and expanding the reach of active and passive defenses becomes as crucial as developing new generations of aircraft. The current fifth generation platforms, like the F-35represent the minimum necessary to operate in a saturated airspace, although they are no longer sufficient on their own to guarantee that depth penetration. The fighters sixth generation should incorporate comprehensive invisibilityintelligent signal management, accompanying drone swarms (already is being tested) and autonomous capabilities selection and attack of targets located behind increasingly complex defensive networks. That is, where a pilot of the past relied on his expertise and the terrain, the pilot of the future will depend of complete ecosystems of manned and unmanned platforms, permanent connectivity and tactical analysis in real time. A basic truth. The recent experience It shows that modern war punishes those who renounce air dominance. Without going too far, in Ukraineboth sides have lost the ability to operate freely over enemy territory due to dense, mobile and highly sophisticated defenses. This aerial stalemate has prolonged the conflict, increased reliance on drones and missiles, and reduced operational mobility on the ground. The warnings from Western commanders underscore the urgency of learn from this scenariobecause the speed of change only increases. The next decade points to challenges driven by both states and non-state actors, with advanced systems becoming cheaper, more accessible and more difficult to neutralize.

In China they have created a material for their fighters that opens a new technological direction: it aims directly at radars

From the early days of World War II to the stealth fighters of the 21st century, the goal of remaining unnoticed by the enemy has been a constant obsession in military aviation. Aerial “invisibility”, more than a myth, It is a technological challenge that has marked decades of innovation in materials and design. A team from Chinese universities describes a flexible and ultra-thin coating capable of absorbing radar waves without losing thermal resistance, collects SCMP. If its effectiveness is confirmed in flight, it could change the conversation about modern aerial stealth. The development was detailed on October 14 in Advanced Materials. The study, signed by Cui Guang, Liu ZhongfanHuihui Wang and Maoyuan Li, among others, presents a graphene-on-silica-fabric (G@SF) metasurface that combines flexibility, low weight and thermal resistance of up to 1,000 degrees Celsius. According to its authors, the direct integration of the material into the insulating layer of an aircraft would allow the reflected radar signal to be reduced to −42 dB, without compromising the structure or weight of the aircraft. A surface that wants to defy the radar The material is based on a silica textile base on which the researchers deposited graphene using a chemical vapor deposition process. On that layer they applied a laser “erasing” technique, which allowed them to create a precise pattern on the surface and adjust your electrical impedance. In this way, they claim, they managed to make the coating effectively absorb electromagnetic waves without needing to increase its thickness or weight. The result is a flexible, ultralight metasurface with an adjustable sheet resistance between 50 and 5,000 ohms per square. {“videoId”:”x9ri2iu”,”autoplay”:false,”title”:”How China, the biggest polluter on the planet, has also become the complete opposite”, “tag”:”webedia-prod”, “duration”:”740″} Laboratory tests showed that the material maintains stable performance even under extreme conditions. After five minutes of exposure to 600 degrees Celsius in air, it retained its absorption capacity, and also withstood prolonged heating to 1,000 degrees in a vacuum without degrading. In tests with air currents of up to 200 meters per second, its loss of efficiency was less than 1%, and neither the surface pattern nor the resistance of the sheet were altered. These properties make it an ideal candidate for high-speed aircraft exposed to intense heat and friction. Withstood prolonged heating to 1,000 degrees in vacuum without degrading The material described in the study poses a possible alternative to conventional coatings, although it has yet to be demonstrated whether its advantages are sustainable outside the laboratory. US stealth fighters, such as the F-22 and F-35they use absorbent compounds They offer good initial performance, but require constant and expensive maintenance. In China, the J-20 has been seen with a coating apparently more stable, although those impressions come from displays and not verifiable technical data. The difference, for now, is in the discourse rather than the evidence. The new coating is still far from becoming a technology in real use, but it illustrates the direction of Chinese research in stealth materials. The challenge is not only to achieve high performance in the laboratory, but to keep it in flight and under extreme conditions. Chinese scientists aim to solve one of the most persistent limitations of modern fighters: the fragility of absorbent coatings. If the material achieves this stability, it could open a different stage in aircraft protection. In Xataka We believed that the F-16s were Ukraine’s great achievement: it has just taken the first step to receive up to 150 European Gripen fighters Beijing has set 2035 as the horizon to complete the modernization of its armed forces. In this context, the development of new compounds, sensors and materials responds to a broader policy aimed at strengthening its technological and military industry. Each advance in the field of stealth materials is interpreted not only as a technical improvement, but also as a step towards greater strategic independence.

The DGT will install 122 new radars in 2025. Locations and when they will begin to fine the 24 radars that are already active

The radars save lives and in 2025 we will continue with the installation of 122 new devices on the Spanish roads, of which 17 fixed and 7 section entered service this January 21 With these words, Fernando Grande-Marlaska, Minister of the Interior, confirmed that The DGT will install more than a hundred radars This year 2025 on Spanish roads. Thus, the head of Interior stressed that the fulfillment of the speed limits “is key” to avoid accidents. The DGT has been defending that installing New radarsas well as the use of vans and even camouflaged motorcycles With mobile radars, you should improve accident figures on roads. The organism has been doing special emphasis on speed although Distractions are the main cause of accidents With mortal victims on our roads. Be that as it may, what is certain is that the DGT aspires to deploy 122 new radars on Spanish roads. All new radars and where will they start fine Although in its information the DGT has also made it clear that its intention is to install a greater number of section radarsfor now, the 24 new radars that already work on Spanish roads are mostly fixed. As you can check in the list below, only seven of the 24 new speed controllers They are stretch. The rest, the 17 new radars are fixed. This is confirmed by the DGT that, in addition to its locations, has confirmed that they came into operation on January 21. That does not mean, however, that they are already sanctioning with fines that can reach the 600 euros and six points in the driving card. At the moment, the cinemometers will pass a first test phase in which only the drivers will be notified that have exceeded the maximum allowed speed. That period lasts a month and, later, the drivers will be sanctioned. As for its locations, the DGT confirms that the 17 fixed radars are found in the following places: Province Road Kilometer point (PK) Almería A-1050 1+200 decreasing Almería AL-3117 1+400 growing grenade N-432 425+950 decreasing Malaga A-7054 3+500 growing A Coruña AC-221 2+550 growing A Coruña AC-841 9+800 decreasing Asturias N-634 377+850 growing Asturias GJ-10 0+250 growing Lugo LU-862 74+150 decreasing Ourense N-525 237+880 growing Pontevedra N-550 84+150 growing Alicante N-332 89+050 decreasing Alicante CV-86 13+800 growing Alicante CV-905 7+050 decreasing Alicante A-77a 0+420 growing Valencia V-31 6+125 d Valencia CV-410 3+510 c The seven new section radars are found in the following locations.
