Les projets d’aérostats, militaires et civils, se multiplient

Air & Cosmos observe que les projets d'aérostats militaires et civils se multiplient ces dernières années. En novembre 2021, l'armée de l'Air israélienne a présenté son programme « Sky Dew », un ballon équipé d'un radar de haute précision qui doit être déployé dans le nord du pays. En France, l'entreprise A-NSE produit des aérostats au profit du Bataillon de Marins Pompiers de Marseille, qui a utilisé un appareil (le T-C60L) pour surveiller le risque d'incendie sur le Parc national des Calanques. Frontex a employé un appareil du même constructeur pour surveiller la frontière entre la Grèce et la Turquie, de même que l'armée allemande au Niger. L'entreprise Flying Whales travaille quant à elle avec l'ONF (Office National des Forêts), pour transporter du bois depuis des régions inaccessibles aux moyens classiques. L'armée française a lancé un contrat d'études, confié à Thales et Thales Alenia Space, pour un dirigeable HAPS (High Altitude Platform System), le Stratobus, doté de quatre moteurs électriques et mesurant 140 mètres de long, qui devrait s'élever à 20 km d'altitude et remplir un rôle d'ISR (Intelligence, Surveillance and Reconnaissance), tout en étant capable d'établir un réseau de communication d'urgence.

    Focus sur Athea, la société commune à Atos et Thales qui doit développer un logiciel souverain pour l'analyse de données

    Les Echos se penchent sur le contexte entourant la création d'Athea, la société commune à Thales et Atos visant à développer une plateforme souveraine associant traitement de données massives et intelligence artificielle pour les secteurs de la défense, du renseignement et de la sécurité intérieure, dont le lancement a été annoncé la semaine dernière dans le cadre du programme technologique de la direction générale de l'armement (DGA). Destinée à développer un logiciel souverain dont les états-majors auront la pleine maîtrise, Athea a vocation à devenir un champion européen de l'analyse de données en grandes quantités (Big Data) pour les armées et le renseignement, capable de rivaliser avec l'américain Palantir. « Nous avons énormément de projets à venir car l'intelligence artificielle permise par l'analyse de grandes quantités de données est de plus en plus utile pour les militaires, que ce soit pour le renseignement, la cybersécurité ou la logistique des forces armées », souligne Marc Darmon, le directeur général adjoint de Thales. « Notre ambition est d'être l'outil qui réponde aux besoins techniques des programmes de défense et de sécurité », précise-t-il.

    Rafael hopes quantum technology can help in GPS-denied environments

    Seth J. Frantzman Rafael Advanced Defense Systems has been investing in quantum technology in the hopes that it will improve existing sensors on the battlefield and could lead to a solution for GPS-denied environments. Because the technology is linked to better positioning, navigation and time-keeping, company leaders said they believe it could “revolutionize” this space. Alternative means of PNT have become a priority for militaries throughout the world as jammers become less expensive and more ubiquitous while the reliance on PNT information increases. In particular, Rafael executives are encouraged that “extremely high-performance quantum accelerometers and gyroscopes can be designed to be the basis of the next generation inertial navigation systems,” a company official said. These sensors can exploit the quantum properties of atoms to measure acceleration and angular rates with unprecedented accuracy, which, in turn, allows for “dead-reckoning navigation for relatively long periods of time while essentially keeping GPS/GNSS accuracy.” Rafael's team working on quantum technology, which includes Alon Gabbay, head of miniature quantum sensors group of the Manor division and Nitzan Link, of the CTO Technology Center of the Manor Division of Rafael Advanced Defense Systems, were among those who discussed the potential for the technology with Defense News. Quantum technology is about sensors that “measure discrete energy levels and difference in change with magnetic or electric fields,” a Rafael official said. The struggle for engineers has been that while this technology has existed for decades, particularly in university labs, miniaturizing it and using it in defense systems is a challenge. While Rafael is traditionally Israel's research and development arm for new weapon systems, it is also the company behind the Trophy defense system, Litening targeting pod and Iron Dome air defense technologies. Rafael has also rolled out new digitized battlefield concepts and used optics to better match scenes and leverage artificial intelligence. “Quantum technologies can give rise to ultra-sensitive gravitational and magnetic measurements, hence opening the possibility of using anomaly maps to aid inertial navigation,” a company official told Defense News. “Atomic clocks use quantum technologies to provide highly stable and accurate frequency standards; the resulting technology can be used for time-keeping opening new possibilities for using communications as an aid to an integrated navigation system.” https://www.c4isrnet.com/industry/2020/12/08/rafael-hopes-quantum-technology-can-help-in-gps-denied-environments/

    The Pentagon can now buy US-made small drones from these five companies

    By: Charles V. Peña The first COVID-19 clusters appeared in Italy in late February, and by early March the Italian authorities issued a decree to install strict public health measures, including social distancing first in the affected regions and then nationwide. Soon afterward, Spain, France and many other European countries instituted similar public health measures. Without debating the efficacy of those measures, the important takeaway is that when faced with what was viewed as a clear and present danger, European countries acted in their own self-interest without having to depend on the U.S. to counter the threat posed by COVID-19. They need to take that same approach for their own security and responsibilities under NATO. It is not a question of resources or capabilities — it is largely a matter of political will. The low hanging fruit for our European NATO allies is to meet their pledge of spending 2 percent of their gross domestic product on defense. Currently nine countries meet that threshold: the United States (3.42 percent), Bulgaria (3.25 percent), Greece (2.28 percent), the United Kingdom (2.14 percent), Estonia (2.14 percent), Romania (2.04 percent), Lithuania (2.03 percent), Latvia (2.01 percent) and Poland (2 percent). Noticeably absent are Germany (1.38 percent), France (1.84 percent) and Italy (1.22 percent) — the fourth, seventh and eighth largest economies in the world. These are wealthy countries that can afford to make the necessary investment. Indeed, the combined GDP of NATO Europe is nearly on par with the U.S. — about $17.5 trillion versus about $20 trillion. Yet, the U.S. spends more than double on defense than our European NATO allies. Other than political will, there is no real reason that European NATO countries cannot spend 2 percent of their GDP for their own defense. Yet, even though Germany previously pledged to meet its 2 percent obligation, Berlin is proposing a new metric based on a country's defense needs — perhaps because U.S. President Donald Trump has stated that he wants European allies to spend 4 percent of their GDP on defense (a metric even the U.S. does not meet). Beyond spending, there is the question of what threat NATO should counter. Originally created in 1949, NATO was intended to counter the Soviet military threat and communist expansion. At the height of the Cold War, the Soviet Union and its Warsaw Pact allies had some 4 million troops and 60,000 main battle tanks deployed against Western Europe — and threatened invasion via the North German Plain, Hof Corridor and Fulda Gap. But today's Russian Federation is not the Soviet Union. Nonetheless, NATO's European countries have the resources to counter a Russian military threat (although it's worth noting that NATO Secretary General Jens Stoltenberg recently said: “We don't see any imminent threat against any NATO ally.”) NATO Europe's combined GDP is 10 times larger than Russia's — more than $17 trillion versus $1.7 trillion. And current defense spending is also in Europe's favor by more than 4-to-1 ($287 billion versus $65 billion). Again, there is no practical reason why NATO Europe cannot make the necessary investments to provide for its security. It is more a question of political will. Moreover, if NATO is concerned about Russia as a potential threat, it should think twice about continuing to expand the alliance eastward onto Russia's doorstep. Rather than providing increased security, it may do more to provoke the Russian bear. Part of the problem is that NATO has largely strayed from its original purpose of collective defense against the Soviet Union (and now Russia). According to the NATO website, the organization is “an active and leading contributor to peace and security on the international stage” that “promotes democratic values and is committed to the peaceful resolution of disputes” with “approximately 20,000 military personnel ... engaged in NATO operations and missions around the world.” If Russia is deemed a threat to Europe and NATO, then the European members of NATO need to take primary responsibility for defending themselves against that threat — and they should view that threat widely to include Russian cyberthreats as well as misinformation and disinformation campaigns meant to undermine elections. That doesn't mean a U.S. withdrawal from NATO. But it is long past the post-World War II era when European countries were struggling to regain their footing and needed America to be the bulwark of its defense. Europe as a whole is today an economic powerhouse — second only to the United States. NATO Europe can and should do more to provide for its own security rather than depending on the U.S. to act as the front line of its defense. All that needs to happen is for those countries to be as serious as they were with COVID-19 and take the same approach to national security as they did when the pandemic began. Charles V.
