La Luftwaffe ne posséderait que 4 chasseurs Eurofighter aptes au combat

Suite à l'absence de munitions et à des problèmes techniques rendant les appareils «aveugles», seuls 4 des 128 chasseurs Eurofighter dotant l'armée de l'air allemande sont aptes au combat.

L'écrasante majorité des 128 chasseurs Eurofighter équipant la Luftwaffe ne sont pas aptes au combat, relate l'hebdomadaire Der Spiegel, se référant à ses propres sources.

D'après l'édition, la cause réside dans le problème que présentent des containers avec des capteurs spéciaux installés sur les ailes des appareils et appelés à déterminer l'approche des avions ennemis. Or, le système de refroidissement de ces dispositifs, précise Der Spiegel, présente de graves dysfonctionnements, ce qui rend les avions de combat «aveugles» et réduit l'efficacité de leur utilisation.

Un autre problème cité par les interlocuteurs de l'hebdomadaire d'investigation résiderait dans le manque de munitions. Ainsi, selon les données fournies par l'édition, seuls quatre chasseurs Eurofighter sont actuellement aptes au combat suite au manque de missiles.

Tentation dangereuse: le F-35 pour l'Allemagne, une menace potentielle pour l'Europe

L'Eurofighter Typhoon est un chasseur polyvalent de la quatrième génération fabriqué par Eurofighter GmbH et exploité par l'Allemagne, l'Autriche, l'Arabie saoudite, l'Espagne, l'Italie et le Royaume-Uni. L'appareil en question est entré en service en 2003.

Plus tôt, les médias allemands ont rapporté que les avions Tornado ne se conformaient pas aux normes de l'Otan. Il a été indiqué que les 93 appareils avaient besoin d'une lourde modernisation. En même temps, la ministre allemande de la Défense, Ursula von der Leyen, a déclaré que ces appareils seraient exploités jusqu'en 2035.

    Army’s Shift To FVL Poses Big Risks For Small Suppliers

    After decades of building traditional helicopters in traditional ways, contractors must get ready for the Army's new high-speed Future Vertical Lift aircraft. Small makers of key parts need help. By SYDNEY J. FREEDBERG JR.on May 06, 2020 at 2:14 PM WASHINGTON: What worries the Army's aviation acquisition chief as he helps industry get ready to build a revolutionary new generation of aircraft in the midst of a global pandemic? “It's the mom and pop shops,” Patrick Mason said today. “It's the Tier 3 suppliers, typically on the hardware side.” “Those are the ones we remain focused on, because those are those are the ones that can end up in a single point failure,” the program executive officer for Army aviation continued. “That's what we're doing right now through COVID and we're going to continue to do that as we look ...to Future Vertical Lift.” While the big Tier 1 prime contractors should be fine, they depend on smaller Tier 2 suppliers for key components, and they depend on yet smaller Tier 3 suppliers. As you trace the provenance of a crucial component down that supply chain, you all too often find a single point of failure. That's some tiny, easily overlooked company that happens to have the only people who know how to build a particular part, like an actuator or a valve, or the only one who can apply a particular heat treatment or protective coating to someone else's part so it can survive the stresses of flight. It would be easier if the Army was just winding down production of one kind of traditional helicopter and ramping up another. Then industry could build any new parts required in the old way. But Future Vertical Lift is about building new kinds of aircraft in new ways. Even the most traditional-looking competitor, Bell's proposal for the FARA scout helicopter, is being designed, built, and tested using new digital tools. Those tools allow much greater precision and efficiency than traditional blueprints, but only for facilities that have the necessary technology installed. Bell and its rivals, Sikorsky and Boeing, are also all eager to use 3D printing and other advanced manufacturing techniques to improve the performance and reliability of key parts while reducing their cost. That's another set of new technologies that small firms can't easily afford. Will increasing sales of drones help make up the revenue? In addition to the optionally manned FARA scout and FLRAA transport, which will have human crews aboard for most missions, FVL is also building a whole family of completely unmanned aircraft. The major companies can get in on much of that business, Mason said, but some of their smaller suppliers can't. If you build electronics or write flight control software, then. you can work on either manned or unmanned aircraft. But, Mason said, if you specialize in building a particular kind of hardware for manned aircraft, most drones are so much smaller that they use entirely different systems, such electric actuators instead of hydraulics. So for small manufacturing shops, he said, “there's less synergy.” Mason's concerns were well supported by a study of the FVL industrial base by the Center for Strategic & International Studies, released today. “The primes are all in,” said Andrew Hunter, director of defense industrial studies at CSIS, who hosted yesterday's call, “[but] it's a big challenge for those Tier 3 and lower suppliers to make this transition.” During months of workshops with industry, “the concern that we heard expressed repeatedly was lower down the supply chain, [with] Tier 3 and lower suppliers,” Hunter said. “It's an expensive investment that they may be challenged to raise the capital to do, [and] it certainly will involve retraining their workforce to use these new manufacturing techniques.” “Industry has to see they're going to get a return on that investment,” he said. “Even optimistic management who are true believers and think they are definitely going to get a return on this investment because they're going to win [FVL contracts], they've still got to justify it to the banks. They've still got to justify it to their corporate boards.” Changing The Rules What complicates the business case for contractors is that the Army wants a new approach, not just to building the new aircraft, but also to how it keeps them flying. Over an aircraft's decades in service, the long tail of operations, maintenance, and upgrades dwarfs the up-front cost of research, development, and acquisition. While the CSIS study calculated that the Army could afford to build the Future Vertical Lift if budgets remain near historical averages – not guaranteed in the wake of the pandemic – the bigger risk is whether or not the service can control those Operations & Sustainment costs in the long term. Army Futures Command's director for aviation modernization, Brig. Gen. Walter Rugen, said he was confident that extensive physical prototyping and digital modeling would help the service get a handle on those costs. “Our requirements... are still in draft form, so if we need to trade one away to maintain our budgets, we will do that,” he said. “We are going to understand to the greatest degree possible what our O&S costs are and make sure that it's within our budget.” For helicopters, Hunter said, O&S is typically 65 percent of the total cost over the lifetime of a program. Now, not all that money goes to aerospace contractors, since sizable chunk goes to pay military maintenance personnel, buy fuel, and so on. But contracts to sustain existing aircraft are a more important revenue stream for most contractors than actually building new ones. While projected spending on R&D (blue) and procurement (red) rise and fall, remaining under $2.5 billion a year, Operations & Sustainment costs (green) remain largely constant at over $7.5 billion — a crucial source of cash for industry. (CSIS graphic) So any Army effort to economize on operations & sustainment hits contractors where they live. What's more, the Army isn't just trying to squeeze savings out of the existing process; it's changing the rules of the game. Historically, companies could bid low to build a new weapons system because, once they got the contract, they had a de facto monopoly on maintaining and upgrading that system for decades. Now the Defense Department is pushing hard to break this “vendor lock” in two main ways: It's increasingly requiring companies to hand over their intellectual property and technical data. The government can then give that data to potential competitors trying to build cheaper alternatives, as on the Army-run Joint Light Tactical Vehicle program. Second, it's requiring companies to make their products compatible with government standards for how different components fit together physically and connect electronically, with the aim of creating Modular Open System Architectures where you can swap out one company's component and replace it with another vendor's. Developing a common MOSA for all manned and unmanned aircraft is a top priority for the Army's Future Vertical Lift initiative. “Part of what we're doing [over] the next year, year and a half, is the strategy associated with the operational availability, that we want out of these platforms, the intellectual property we want to obtain,” Mason said. “What's the valuation of the IP, the intellectual property? Because intellectual property drives their ability to control the aftermarket, and the aftermarket is where you see the year over year cash flow [that's] critical to most of their business models.” “As you look at Modular Open System Architecture...the business case and the business model associated with it is something that we're working through with industry right now,” Mason said. “It is critical that we have the right incentive structure, it is critical that we provide the right framework so that industry continues to invest and they continue to see a return on that invested capital.” To prevail in future conflicts, “we can't afford not to do Future Vertical Lift,” Brig. Gen. Rugen said. “What this report talks to is national interest we have in preserving the rotorcraft industrial base as we go forward.” https://breakingdefense.com/2020/05/armys-shift-to-fvl-poses-big-risks-for-small-suppliers/

    Here are some new tools coming to protect the supply chain

    By: Andrew Eversden The Department of Defense is working with a unnamed company to mitigate cybersecurity vulnerability discovered in a technology used by the Pentagon, the DoD's Deputy Chief CIO Michele Iversen said Nov. 12. Without going into specific detail, Iversen said the department is working to remove the product. “The company was compromised [and] had a big cybersecurity vulnerability,” said Iversen, speaking at Fifth Domain's annual CyberCon conference. “And we have seen bad things coming from those products, so we are looking at how to use our authorities ... [to] block those products or companies for national security systems.” This highlights a broader issue facing the DoD: how to protect its supply chain. To mitigate supply chain risk, Iversen said that she is working on a supply chain illumination tools. She said that these are useful because its made up of publicly available information that doesn't need any level of classification. Specifically, she said she's working on a decision support tool where she can expose a “bare minimum set of publicly available supply chain information.” “So when people are going to look and make their purchases, they have information available to them,” she said. She said, ultimately, she wants the DoD CIO's office to offer that tool as a service. The National Institute of Standards and Technology is also starting to develop cybersecurity tools. NIST's Jon Boyens, acting deputy chief of the computer security division, said that his team at the standards agency is working on a supplier inter-dependency tool “to look at different suppliers and their criticality” to allow for government to be more effective in asking for capabilities during the procurement process. “Industry is saying, ‘You know, we've invested in this but we're not getting any incentives' ... and so they're kind of looking for incentives for investing in technology,” said Boyens. Iversen said that technology research and development also presents its own attack surface with which it needs to grapple. If the research and development was done in a foreign country, that presents a unique set of threats. For example, Iversen pointed to back-up software being placed into a nuclear command-and-control system. “Maybe you just say anything where the R&D ... [is] done in those countries is just off limits,” Iversen said. “It just makes common sense. It's fixing stupid.” https://www.fifthdomain.com/smr/cybercon/2019/11/12/here-are-some-new-tools-coming-to-protect-the-supply-chain/

    Marines’ Next High-End Fight Could Call for Larger Formations, Tougher Amphibs

    By: Megan Eckstein ARLINGTON, Va. – The Marine Corps is preparing for a high-end distributed fight inside island chains in the Pacific, and the service is pushing the Navy to invest in additional weapons and systems for amphibious ships to support this kind of battle in a contested environment. The Marine Corps is further developing concepts like the Expeditionary Advance Base Operations and Littoral Operations in a Contested Environment, but there are some materiel changes the Navy will need to make, such as upgunning amphibious ships and connecting amphibs into the surface combatants' and aircraft carriers' tactical grid, leaders said last week at the Surface Navy Association's annual national symposium. Maj. Gen. David Coffman, director of expeditionary operations (OPNAV N95), set the scene, describing a large-scale formation Navy ships and Marine landing forces beyond what the services typically rehearse today. “That level of integrated naval operations could be needed to take an island somewhere – natural or manmade. But it certainly will be required when a great power competition pits a whale against an elephant, or maybe two elephants – a global maritime power, that's us, against a regional land power hegemon with home-field advantage. In that long war, maritime superiority is necessary but not sufficient for the whale to beat the elephant,” Coffman said, noting the Marines were readying themselves to conduct day-to-day competition, deterrence against malign actions, and, if necessary, major combat operations in this high-end environment. “So what we need to do is reinvigorate naval maneuver warfare, linking sea control and power projection in order to win current and future fights.” Full article: https://news.usni.org/2019/01/23/marines-next-high-end-fight-call-larger-formations-tougher-amphibs
