Rafale pour la Grèce : entretien avec Eric Trappier, PDG de Dassault Aviation
|
Eric Trappier, PDG de Dassault Aviation, s'exprime dans Le Figaro. Il souligne notamment que L'intention manifestée par la Grèce, samedi soir, d'acquérir 18 avions de combat français Rafale «est une bonne nouvelle pour la France et pour son industrie aéronautique, dans le contexte difficile de la crise du Covid-19, marquée par un effondrement de l'activité sur le marché civil. C'est aussi une bonne nouvelle du point de vue politique avec un renforcement des relations entre les deux pays méditerranéens que sont la Grèce et la France. Et, enfin, c'est une bonne nouvelle pour Dassault Aviation et les partenaires du programme Rafale». Les Rafale sont appelés à remplacer la flotte de Mirage 2000 d'ancienne génération grecque, et à renforcer les capacités de défense et d'attaque du pays aux côtés des Mirage 2000-5 plus récents et des F-16 américains, en cours de modernisation. «Le premier ministre grec nous a demandé d'aller vite afin que les avions entrent rapidement en service dans leurs forces. Aussi, allons-nous tout mettre en œuvre afin d'aboutir à la signature du contrat commercial avant la fin de l'année. C'est ambitieux mais nous avons déjà démontré, notamment avec notre client égyptien, que nous savions répondre présents dans des délais très courts», explique Éric Trappier. La Grèce, client historique de Dassault depuis 1974, devient le tout premier client européen, membre de l'Otan, du Rafale. Il s'agit, pour l'avion de combat français, du quatrième succès à l'exportation, après l'Égypte et le Qatar en 2015 puis l'Inde en 2016, rappelle Le Figaro. «C'est encore une exception en Europe qui, je l'espère, montrera l'exemple à d'autres pays», souligne Éric Trappier.

The Pentagon wants help for its satellites to talk to each other
By: Nathan Strout The Space Development Agency wants its satellites to be able to easily talk to each other and is considering using optical intersatellite links for communications within its future low earth orbit space architecture. Now, the organization is looking for industry's help on what standards should be used for those links. On Jan. 15, the agency issued a request for information to industry to inform its attempt to establish an Optical Intersatellite Link Open Standard. Most satellites don't speak with each other directly. Instead, they utilize radio-frequency communications with a ground station to relay communications between satellites. Some satellites, however, are able to use optical links to provide direct communications between satellites without a ground station acting as an intermediary. The SDA wants to use this technology for what it calls its “transport layer,” the backbone of its plans for a new space architecture in low earth orbit. The SDA was established in March 2019 to design the Department of Defense's future threat-driven space architecture, a setup it has since defined as a multi-layered constellation of hundreds of small satellites providing several capabilities from LEO. The SDA will not be directly responsible for every layer or constellation within the architecture — most notably, the Hypersonic and Ballistic Tracking Space Sensor is being developed primarily by the Missile Defense Agency — however, the SDA will be the agency in charge of integrating those various efforts into a single architecture. Key to the entire enterprise is the Tracking Layer, a family of satellites in low earth orbit that will facilitate the flow of data between satellites in orbit and between satellites and the ground. The Transport Layer will be essential in connecting the various sensors and capabilities on orbit with weapons systems on the ground or in the air. In order to build that capability, the SDA plans to use Optical Intersatellite Links. The optical links will also need to provide range estimates of the distance between satellites in orbit and between satellites and the ground to within a meter in order to provide highly precise timing and positional data for the constellation. The SDA also envisions each satellite utilizing a chip-scale atomic clock as well as GPS signals. The problem is that there are currently no industry standards for those links. To ensure the interoperability of various vendor technologies used for those links, the SDA wants to establish that standard, and it's asking industry for help. Responses are due by Feb. 5. More specifics about what the SDA is considering for its standards is available on beta.sam.gov. According to the request, the SDA plans to issue a solicitation for Tranche 0 of the Transportation Layer in Spring 2020, with additional solicitations for the other capability layers to follow in the summer. That first tranche, known as the war fighter immersion tranche, will consist “of tens of satellites providing periodic, regional sensing and data transport capabilities, including the capability to detect hypersonic glide vehicles and to disseminate time sensitive targeting solutions over tactical data links.” According to the agency, that initial tranche could be delivered as early as fiscal year 2022 https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/01/16/the-pentagon-wants-help-for-its-satellites-to-talk-to-each-other/

Navy Turns To AI To Save Billions In Fight Against Rust
By KELSEY ATHERTON ALBUQUERQUE: The Navy is using Google Cloud to speed up a basic but time consuming task: finding and identifying rust. This approach has already been applied to inspect wind turbines and find potholes in roads, and promises advantages both in speed of inspection and in future predictive maintenance. “The AI technology behind this enabled the US Navy to quickly and seamlessly examine tens of thousands of images to prioritize the needs to be repaired immediately and or later on,” Mike Daniels, vice president of Global Public Sector, Google Cloud, told me in an interview. While Google was unwilling to disclose the exact value of the contract, the promise is that speedy, AI-enabled inspections will lower labor and material costs of inspection and repair enough to more than justify the expenditure on inspection AI. “The tools we're providing can not only save the Navy billions each year, but significantly improve readiness and speed deployment,” said Daniels. “And this is a physical job right now. We're improving results for the inspectors.” If AI-facilitated rust inspection can reduce the amount of time a ship needs to stay in harbor for repairs, it can narrow the window in which catastrophic disasters, like the fire which tore apart the Bonhomme Richard, can happen. This work is being done through Simple Technology Solutions (STS), who was awarded the work as a Phase 1 Small Business Innovation Research project. To train the AI, STS flew a drone on inspections to get images of rust. Next, STS combined these drone-filmed images with public domain images of ships, and uploaded both sets to a Google Cloud server. Specifically, the inspections will look for broad area rust and corrosion, as well as subtler damage that human eyes might skip over, like pitting or focused damage. Using native machine learning built into the Google Cloud, STS could then train the algorithm to process, understand and identify rust in the images. This is an iterative process, one where every uploaded inspection improves the accuracy of the next inspection. “There's no classified data that's going to be handled as part of this project,” said Daniels, noting that Google offers a high level of protection for images stored in its cloud by default. As we have seen in the past, aggregated unclassified data can sometimes be enough to reveal classified information, but the immediate utility of cloud-powered inspections should offset any distant concern of weakness revealed through corrosion maintenance. Most importantly, the inspection tool promises savings in time. A widely-cited 2014 report from the US Navy attributed the cost of fighting rust and corrosion at $3 billion. Some of that cost is hard to shake: the paint used to cover rust-scrapped areas can cost as much as $250 a gallon. Catching corrosion quickly and early shortens the amount of time humans need to work to fix a vessel, and should reduce the area that needs repair for each inspection. https://breakingdefense.com/2020/08/navy-turns-to-ai-to-save-billions-in-fight-against-rust/
