Premier vol opérationnel d’un Rafale F3-R équipé de 2 missiles Meteor

L'armée de l'Air et de l'Espace a effectué le 4 mars son premier vol opérationnel avec un Rafale équipé de 2 missiles Meteor. L'intégration du missile Meteor entre dans le cadre de la montée en puissance du Rafale F3-R de Dassault Aviation. Le missile Meteor, développé par MBDA, est propulsé par un statoréacteur pilotable qui lui apporte vitesse, portée et manoeuvrabilité terminale. Son intégration « apporte une allonge considérable dans le combat air-air, avec une portée estimée à une centaine de kilomètres », précise Aerobuzz. Son emploi se conjugue à celui du radar RBE2 AESA à antenne active, capable de détecter et désigner des cibles à cette distance. La prochaine étape pour le Rafale en matière de missile concerne l'intégration du MICA de nouvelle génération avec le standard F4, dans les années 2023-2024.

    130 House members want 24 percent more F-35s procured in FY21

    By: Aaron Mehta WASHINGTON — One hundred thirty members of the House of Representatives are asking key defense committees in Congress to increase the number of F-35 Joint Strike Fighters by 24 percent over the number requested by the Pentagon in fiscal 2021. “Our adversaries continue to advance surface-to-air missile systems and develop their own stealth fighters,” read the letter, released Wednesday. “It is essential that we continue to increase production of our nation's only 5th generation stealth fighter in order to ensure the United States maintains air dominance and to further reduce overall program costs.” The letter, addressed to the chairs of the Senate and House Armed Services committees and Appropriations Defense subcommittees, is authored by Reps. John Larson, D-Conn.; Marc. Veasey, D-Texas; Martha Roby, R-Ala.; and Michael Turner, R-Ohio — the four leaders of the bipartisan F-35 caucus. Last year, the four also joined forces to write a similar request, which garnered 103 signatories. The Defense Department's budget request asks for 79 F-35s, including 48 of the F-35A model used by the Air Force, 10 F-35Bs used by the Marines and 21 F-35C models used by the Navy. In the letter, the congressmen note that number is 19 less jets than Congress appropriated in FY20. However, that number creates “a capability gap that 4th Generation, or legacy, aircraft cannot fulfill,” the letter warned. “To reach the minimum 50% ratio of 5th Generation and 4th Generation fighters in the timeframe required to meet the threat, the U.S. must acquire F-35s in much larger quantities.” Instead, the members want a 24 percent increase in fighters procurement, going up to 98 total, including 12 more F-35As, two more F-35Bs and 26 more F-35Cs. Those numbers match the fighter increase listed by the Air Force in its unfunded requirements document sent to Congress earlier this year; the Navy requested only five more F-35C variants, while the Marines did not request more. The letter was first reported by Politico. In addition to the increase in planes bought, the members are seeking additional funding for “spare parts and depot level repair capability to meet the required availability rates and accelerate the stand-up of mandated, organic government repair capabilities.” Additionally, investments are sought for the program dedicated to the jet's reliability, maintainability and improvement, as well as a “long-term, outcome-based sustainment contract” that would guarantee performance metrics at a fixed price. The members then request the committees fully fund the budget request for the continuous capability development and delivery (C2D2) modernization effort and use existing funds to accelerate integration of the Joint Air-to-Surface Standoff Missile onto the jet. Earlier this year, the Pentagon's independent weapons tester called the current schedule for C2D2 “high risk” and said the program office is struggling to stay on schedule. “C2D2 is critical to meeting the evolving threat in the mid-2020s and into the 2030s. Full funding is needed for the delivery of new weapons and critical capabilities necessary to keep the F-35 ahead of our adversaries,” the members wrote. https://www.defensenews.com/congress/2020/03/19/130-house-members-want-24-percent-more-f-35s-procured-in-fy21/

    LOCKHEED MARTIN CONTRACT TO MARRY MACHINE LEARNING WITH 3-D PRINTING FOR MORE RELIABLE PARTS

    U.S. Navy research contract could make complex metal additive manufacturing a reality both in production centers and deep in the field DENVER, Oct. 1, 2018 /PRNewswire/ -- Today, 3-D printing generates parts used in ships, planes, vehicles and spacecraft, but it also requires a lot of babysitting. High-value and intricate parts sometimes require constant monitoring by expert specialists to get them right. Furthermore, if any one section of a part is below par, it can render the whole part unusable. That's why Lockheed Martin (NYSE: LMT) and the Office of Naval Research are exploring how to apply artificial intelligence to train robots to independently oversee—and optimize—3-D printing of complex parts. The two-year, $5.8 million contract specifically studies and will customize multi-axis robots that use laser beams to deposit material. The team will develop software models and sensor modifications for the robots to build better components. Lockheed Martin Metal 3D printer "We will research ways machines can observe, learn and make decisions by themselves to make better parts that are more consistent, which is crucial as 3-D printed parts become more and more common," said Brian Griffith, Lockheed Martin's project manager. "Machines should monitor and make adjustments on their own during printing to ensure that they create the right material properties during production." Researchers will apply machine learning techniques to additive manufacturing so variables can be monitored and controlled by the robot during fabrication. "When you can trust a robotic system to make a quality part, that opens the door to who can build usable parts and where you build them," said Zach Loftus, Lockheed Martin Fellow for additive manufacturing. "Think about sustainment and how a maintainer can print a replacement part at sea, or a mechanic print a replacement part for a truck deep in the desert. This takes 3-D printing to the next, big step of deployment." Currently, technicians spend many hours per build testing quality after fabrication, but that's not the only waste in developing a complex part. It's common practice to build each part compensating for the weakest section for a part and allowing more margin and mass in the rest of the structure. Lockheed Martin's research will help machines make decisions about how to optimize structures based on previously verified analysis. That verified analysis and integration into a 3-D printing robotic system is core to this new contract. Lockheed Martin, along with its strong team, will vet common types of microstructures used in an additive build. Although invisible from the outside, a part could have slightly different microstructures on the inside. The team will measure the performance attributes of the machine parameters, these microstructures and align them to material properties before integrating this knowledge into a working system. With this complete set of information, machines will be able to make decisions about how to print a part that ensures good performance. The team is starting with the most common titanium alloy, Ti-6AI-4V, and integrating the related research with seven industry, national lab and university partners. About Lockheed Martin Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 100,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.

    Coast Guard needs help with IT infrastructure, cloud consolidation

    by Jackson Barnett The U.S. Coast Guard is seeking input on an IT infrastructure consolidation plan that will help migrate part of its system to the cloud to ensure operators around the world have access to critical networks. The request for sources is the first step in what appears to be a plan for the Coast Gaurd to contract with the private sector on IT infrastructure transformation. The idea is to shift IT services to an “Infrastructure Managed Services” model, one that would contract out infrastructure services to private companies to assist in cybersecurity and network optimization. The move spawned from the Coast Guard's fiscal 2018-22 Strategic Plan, which calls for greater cyber strength and efficient IT infrastructure. “The security environment is also affected by the rising importance of the cyber domain – where adversarial nation states, non-state actors, and individuals are attacking our digital infrastructure and eroding the protections historically provided by our geographic borders,” the strategic plan states. The challenge to secure and re-structure the Coast Guard's networks and IT infrastructure span global operations, different security classifications and many data centers, according to the request. The networks support more than 54,000 users worldwide at 823 global sites. The current networks are based on a slew of Microsoft operating systems, some more than a decade old. The Coast Guard has been watching the development of Department of Defense's JEDI cloud contract, Adm. Karl Schultz said in August. Now, the Coast Guard hopes to migrate some of its data to the cloud while keeping some of it on the government servers it operates. “USCG recognizes it must partner with Industry” the request states. https://www.fedscoop.com/coast-guard-cloud-it-consolidation-procurement/
