    Bruxelles veut renforcer l'industrie de défense européenne

    « Je note une véritable prise de conscience que nous devons faire plus ensemble pour construire une Europe de la Défense », a déclaré mardi Thierry Breton, Commissaire européen au Marché intérieur. La Commission a présenté mardi sa contribution au débat en suivant trois axes. D'abord le développement des achats en commun de matériels de défense, pour lequel les Vingt-Sept se sont fixés un objectif de 35%. Des achats communs ont de nombreux avantages, dont des économies d'échelle et une plus grande capacité d'exportation. Pour inciter les Etats membres à plus de collaboration, la Commission envisage des incitations fiscales via une exonération de la TVA, par exemple. Bruxelles réfléchit aussi à revoir le fonctionnement du Fonds européen de défense (FED), qui dispose d'une enveloppe de 7 Md€ sur la période 2021-2027. La Commission veut ensuite identifier les dépendances stratégiques de l'UE pour les réduire. Bruxelles veut inclure systématiquement l'industrie de la Défense dans les grandes initiatives industrielles (dans l'élaboration des normes, par exemple) et renforcer le filtrage des investissements directs de pays tiers. Enfin, la Commission veut protéger « les nouveaux espaces contestés » contre les menaces hybrides ; elle a déjà annoncé un prochain « Cyber Resilience Act » qui doit mettre en place des sortes de gardes-frontières de l'espace cyber européen.

    Australia plans US$190 billion defence boost over decade

    Rod McGuirk The Associated PressStaff CANBERRA, AUSTRALIA -- Australia's prime minister on Wednesday announced 270 billion Australian dollars (US$190 billion) in additional defence spending over the next decade, which will include long-range missiles and other capabilities to hold enemies further from its shores. Prime Minister Scott Morrison warned that the post-pandemic world will become more dangerous and announced a renewed focus on Australia's immediate region, although its military would be open to joining U.S.-led coalitions as it did in Afghanistan and Iraq in campaigns that were in the Australian national interest. Australia had not seen such economic and strategic uncertainty in the region since the Second World War for reasons including tensions between the United States and China, he said. "This simple truth is this: Even as we stare down the COVID pandemic at home, we need to also prepare for a post-COVID world that is poorer, that is more dangerous and that is more disorderly," Morrison said. Tensions over territorial claims were rising between India and China and in the South China Sea, Morrison said. "The risk of miscalculation and even conflict is heightened," Morrison said. "Regional military modernization is at an unprecedented rate." "Relations between China and the United States are fractious at best as they compete for political, economic and technological supremacy," he added. Rory Medcalf, head of the Australian National University's National Security College, said the announcement showed Australia was "getting serious about deterrence and the prospect of armed conflict in the Indo-Pacific region." "It was only a matter of time before the Australian government made a choice about the kind of defence force that we're going to have in the 21st century with the rapid deterioration in the strategic environment in recent years," Medcalf said. "The government has accepted that the Australian military needs to be able to attempt to deter armed conflict through its capabilities and to be able to fight in our region if we have to," he added. Australia will invest in more lethal and long-range capabilities that will hold enemies further from its shores, including longer-range strike weapons and offensive cyber capabilities. To increase maritime strike capability, Australia will buy the AGM-158C anti-ship missile from the U.S. Navy at an estimated cost of AU$800 million, the government said. The new missile is a significant upgrade from Australia's current AGM-84 air-launched Harpoon anti-ship missile, which was introduced in the early 1980s. It has a range of 124 kilometres (77 miles), while the missile being purchased can exceed 370 kilometres (230 miles). The new missile will initially be used on the F/A-18F Super Hornet jet fighters but can be used by other defence aircraft. Training on the weapon system would begin next year, the government said. Australia will also invest in advanced naval strike capabilities, including long-range anti-ship and land strike weapons, and will buy long-range rocket artillery and missile systems to give the army an operational strike capability. It also plans to develop and test high-speed, long-range strike weapons, including hypersonic weapons. The announcement comes as Australia's relationship with China, its most important trading partner, is under extraordinary strain over Australian calls for an independent investigation of the pandemic. The United States, Australia's most important security partner since the Second World War, remains "the foundation of our defence policy," Morrison said. "Of course we can't match all the capabilities in our region," Morrison said. "That is why we need to ensure that our deterrence capabilities play to our strengths." https://www.ctvnews.ca/world/australia-plans-us-190-billion-defence-boost-over-decade-1.5006902

  • How Nanotech Will Help the U.S. Military Reach Mach 5

    How Nanotech Will Help the U.S. Military Reach Mach 5

    The U.S. government is pushing into hypersonic weapons in a big way, with at least five different weapons programs currently in development. Nanotechnology is shaping up to be a key tech that will enable delivery systems to survive traveling through the atmosphere at Mach 5 and above, with carbon nanotubes showing promise as strong, lightweight material that rapidly sheds heat. Hypersonic weapons are weapons that travel at incredible speeds through the atmosphere. Hypersonics start at Mach 5 (3,836 miles an hour), or five times the speed of sound. Pushing an object through the air at really, really fast speeds creates a unique problem: as speed increases, the friction from the object passing through air also increases. This friction generates heat. The skin of the SR-71 Blackbird strategic reconnaissance jet and the fasted manned airplane ever built regularly warmed to up to 500 degrees Fahrenheit at Mach 3. The X-15 rocket plane, flown during the 1960s, reached temperatures of 1200 Fahrenheit as it flew to Mach 6. At Mach 10, the friction is enough to “melt the toughest steel,” while at Mach 20, the temperature reaches an astounding 17,000 Fahrenheit. Eventually, hypersonic weapons could reach Mach 24. Scientists and engineers understand how to handle traditional air friction problems thanks to the technical challenges of spacecraft and nuclear warheads re-entering the atmosphere. But a missile warhead de-orbiting over an enemy target is only exposed to heat for a handful of minutes, as it transitions from space to the atmosphere and finally smashes into its target. A hypersonic weapon, on the other hand, spends its entire flight within the atmosphere and is exposed to high heat the entire time. An article at DefenseOne describes how scientists are working with carbon nanotubes to solve the heat issue. Scientists at Florida State University's High-Performance Materials Institute are looking into using carbon nanotubes as a construction material for hypersonic weapons. Carbon nanotubes are a synthetic material consisting of carbon tubes with a diameter as small as one nanometer. Carbon nanotubes are stronger than steel and insulate against heat. Now, researchers have discovered that soaking carbon nanotubes in phenol can increase their ability to disperse heat by one-sixth, allowing less nanomaterials to be used for the same job. What does this mean for hypersonic weapons? It means that materials that can stand the heat and stresses of hypersonic, atmospheric travel are on the way, and that hypersonic weapon designers could even safely achieve higher speeds by using thicker layers of the stuff. https://www.popularmechanics.com/military/research/a29847271/us-military-nanotech/
