Guerre des drones : le dossier du Monde

Dans les ajustements capacitaires de la programmation militaire, figure notamment la lutte anti-drones, identifié comme un « domaine opérationnel clé dans le récent conflit du Haut-Karabakh » par la ministre des Armées, Florence Parly. En effet, les conflits au Donbass, en Libye, et au Haut-Karabakh ont mis en lumière les vulnérabilités des forces françaises dans le domaine de la défense sol-air de courte et moyenne portées. Pour enrayer cette menace, l'armée de Terre a inauguré en janvier le Battle-Lab Terre sur la base de Satory, à Versailles. Des fusils capables de brouiller les fréquences des drones sont en cours de déploiement et un système de radar raccordé à une mitrailleuse, baptisé « Icare », pouvant détruire des drones à distance a été développé. Il doit équiper, d'ici à la fin de l'année, des véhicules de l'avant blindé. Les forces terrestres recevront également à partir de janvier 2022 le système de drone tactique Patroller (Safran Electronics & Defense). « Le conflit du Haut-Karabakh doit nous ouvrir les yeux sur un changement de paradigme », résume Jean-Baptiste Jeangène Vilmer, directeur de l'Institut de recherche stratégique de l'Ecole militaire (Irsem).

    ‘Gamechanger’ aerial drone arrives in UK after mammoth 24-hour transatlantic flight

    By: Beth Stevenson RAF FAIRFORD, England — General Atomics Aeronautical Systems' developmental MQ−9B SkyGuardian made the first ever transatlantic flight of a medium-altitude, long endurance aerial drone. The unmanned aerial vehicle completed touched down at RAF Fairford in the United Kingdom after a 3,760 nautical mile sortie from the U.S. July 11 that began at the Grand Forks test site in North Dakota 24 hours and 2 minutes prior. The journey was the first transatlantic flight of both the SkyGuardian and any MALE UAV, but also the first U.K. appearance of the UAV that the Royal Air Force will operate under its Protector program. The U.K. is the launch customer for SkyGuardian, and the journey to RAF Fairford to take part in the Royal International Air Tattoo (RIAT) ties in with the RAF's centenary celebrations, as the MQ−9B will be one of the next combat aircraft types delivered to the service. L3 Technologies Communication Systems provided Ku-band satellite communication (SATCOM) to control the UAV throughout the flight with no handover to a control station in the U.K, although Inmarsat Government provided a backup L-band SATCOM capability in case of failure. A line-of-sight ground control station was shipped to Fairford and was responsible for taxiing the aircraft once it had carried out its automatic landing. It flew at approximately 27,000 feet for most of the flight, dropping to 9,000 feet and maintaining a holding pattern near Fairford for some 2 hours ahead of landing, transiting initially via Canada, over to the South of Ireland, and then over Wales before reaching its end destination. Jonny King, vice-president of GA-ASI UK, told a media briefing at Fairford that the transit demonstrates that the UAV is self-deploying, and the journey was relatively routine for the test aircraft — just with a different landing destination. It has previously flown a sortie of more than 48 hours, King noted, and for the transatlantic flight it was able to fly under the U.S. Federal Aviation Administration's authorization, with support from the U.K. Civil Aviation Authority that granted an overflight permission for the transit into U.K. airspace. While the U.K. is on record as being the launch customer for the SkyGuardian through its Protector effort, the aircraft is yet to go through certification testing — one of the most distinguishing features of this variant — and will not be delivered to the RAF until the early 2020s. Development and certification contracts for Protector have been signed, but a production contract for the buy is not expected to be signed for some time, the RAF told Defense News. Air Marshal Julian Young, chief of materiel for air, defense equipment and support for the RAF, said that it is expected that Protector will be acquired under two direct commercial sales contracts and two foreign military sales deals with the U.S. government, covering the various elements of development and acquisition. “Protector is one of the most exciting projects I have to deliver,” Young said, adding that it will be a “gamechanger” in its ability to fly alongside manned aircraft under the remit of air traffic control, with the ultimate goal of being able to fly in open airspace alongside uncontrolled aircraft. “This is a key component of the future of the RAF's air power,” he told media at the aircraft landing event. “I hope this is going to set the standard for aviation. The U.K. is very happy to be the lead with this unique capability.” SkyGuardian has been in test flight for some 18 months so far, King said, adding that the second test aircraft – YBCO2 – will join the first aircraft in test flight in the next month or so. In accordance with the U.K.'s 2015 Strategic Defence and Security Review, the RAF will more than double its MALE UAV capability, which is currently fulfilled by a fleet of 10 Block 1 MQ-9 Reapers, so as few as 21 could be acquired, although 26 is a figure that has been previously touted. The RAF has claimed that integrating UK-made weaponry is a priority for the program, so it will operate MBDA's Brimstone ground attack missile and Raytheon UK Paveway IV laser-guided bombs, although contracts for these have also not yet been signed. “Sovereignty is clearly an important issue,” Young told Defense News, adding that while the Reapers that were bought in the same configuration operated by the U.S. Air Force have been a capability that the U.K. has been able to effectively exploit, more sovereignty would have been an advantage. But “this comes at a cost.” He added that the training capability that the U.K. will use is still undecided on, although the U.K. is open to this taking place domestically or with other partners should another nation elect to acquire aircraft. SkyGuardian will be showcased throughout RIAT before being dismantled and shipped back to the U.S. a week later, King noted. https://www.defensenews.com/digital-show-dailies/riat/2018/07/13/gamechangeraerial-drone-arrives-in-uk-after-mammoth-24-hour-transatlantic-flight/?utm_source=Sailthru&utm_medium=email&utm_campaign=ebb%2016.07.18&utm_term=Editorial%20-%20Early%20Bird%20Brief

    Forum innovation défense : la défense française accélère encore sur l’innovation

    Le Forum innovation défense (FID), qui ouvre ses portes ce jeudi 25 novembre à Paris, est l'occasion de montrer que la défense française « a repris la course en tête » de l'innovation, relèvent les Echos. Les moyens dédiés à l'innovation ont été portés de 730 M€ en 2019 à 1 Md€ dans la Loi de finances 2022, et les méthodes et processus d'aides aux innovations ont été en partie revus pour accélérer sur des sujets tels que l'intelligence artificielle, le quantique, la surveillance spatiale, les armes à énergie dirigée, ou encore l'hypervélocité. L'Agence de l'Innovation de Défense (AID), créée il y a trois ans, a joué un rôle important d'accélérateur. « Le mouvement enclenché pour s'ouvrir aux innovations civiles est désormais bien implanté dans le ministère des Armées », explique le directeur de l'agence, Emmanuel Chiva. Il indique que ses équipes ont référencé 760 startups, et en ont sélectionné 290 pouvant offrir des technologies intéressantes pour le secteur de la défense. Les Echos du 25 novembre

    NASA begins test flights to study physiological events on military pilots

    BY: GARRETT REIM NASA started a several months-long series of flights on 3 August to identify the physiological impacts of flying in high-performance military aircraft on the human body. The flights are being conducted at NASA's Armstrong Flight Research Center at Edwards Air Force Base in California and will take place over 160 flight hours. The tests are managed by the NASA Engineering and Safety Center at Langley Research Center in Virginia. During the tests researchers will measure the breathing of five NASA pilots flying in F-18A/B and F-15D aircraft, while they use different equipment types and experience different flight conditions. The flight conditions that will be tested include benign environments, typical in instrument proficiency training, to more strenuous environments, such as those found in high altitude, aerobatic manoeuvring and combat manoeuvring, according to NASA. In recent years, the US Navy and Air Force have been perplexed by an increase in the number of pilots experiencing physiological events during flight across a variety of aircraft. Symptoms from physiological events include cognitive impairment, numbness, tingling, lightheadedness, behavioral changes and fatigue. Data collected will just serve as a baseline for comparison because NASA's aircraft still use the legacy technology of a Liquid Oxygen System as opposed to newer military aircraft that utilise an Onboard Oxygen System. https://www.flightglobal.com/news/articles/nasa-begins-test-flights-to-study-physiological-even-451308
