Les députés Olivier Becht et Stéphane Trompille viennent de remettre leur rapport sur la stratégie de défense spatiale dont la France doit se doter pour annihiler les menaces actuelles et futures.
La France a décidé de se doter d'une stratégie de défense spatiale et la première étape est ce rapport que les députés Olivier Becht et Stéphane Trompille viennent de rendre devant la Commission de la Défense et des forces armées. L'incident du satellite espion russe en a été l'élément le plus médiatiquement visible et a servi d'accélérateur à une volonté qui était d'ores et déjà en gestation. Après la militarisation de l'espace, Olivier Becht et Stéphane Trompille soulignent dans leur rapport "l'arsenalisation de l'espace avec envoi et présence d'armes qui auront vocation à être utilisées dans le cadre d'un conflit".
Le tout dans un contexte qui a changé : apparition de nouvelles puissances spatiales, l'arrivée de firmes privées sur le marché du spatial et la révolution "nano", soit la capacité de produire des satellites de plus en plus petits "pratiquement indétectables, qui peuvent être équipés d'une capacité de brouillage, d'écoute, de prise de contrôle cyber ou de charges explosives". Par conséquent : "défendre nos satellites civils comme militaires dans l'espace, être capable de voir, d'éviter, d'agir et de neutraliser un menace devient dès lors un enjeu de souveraineté nationale et européenne", soulignent Olivier Becht et Stéphane Trompille.
Pour les auteurs du rapport, cette stratégie de défense spatiale devrait s'orienter autour de plusieurs axes. D'abord en renforçant les moyens de surveillance. Les systèmes de radars GRAVES et SATAM doivent "être complétés par de nouveaux développements" capables de suivre des engins "non-kepleriens" ou "très manoeuvrants et suivant des orbites non habituelles". Solution préconisée : deux nouveaux systèmes de radars de veille en orbite basse installés, l'un en métropole, l'autre en Guyane. Les rapporteurs préconisent aussi la mise en place "d'un système de surveillance des orbites géostationnaires" avec l'achat de trois télescopes supplémentaires (Polynésie, Nouvelle Calédonie) en plus du système TAROT du Cnes. "La surveillance de l'espace devra aussi pouvoir s'effectuer depuis l'espace : emport de capteurs d'approche sur nos satellites, mise en orbite de satellites patrouilleurs, surveillance de nos satellites par un petit satellite de type "chien de garde".
Deuxième axe : la capacité de neutraliser une menace dans l'espace. Les deux parlementaires préconisent, plutôt que l'usage de missiles anti-satellites, de développer de nouvelles technologies : laser ionique "affectant les capteurs qui équipent les voies haute résolution visibles du satellite en le rendant momentanément inopérant, laser classique permettant de détruire chirurgicalement un équipement donné d'un satellite; moyens cyber pour brouiller ou détourner un satellite, bras articulés montés sur un satellite ou une mini-navette permettant d'arrimer un satellite hostile, de le dévier de son orbite et de l'envoyer vers les confins du système solaire.
Enfin, pour être en capacité de poursuivre les missions "en cas de neutralisation de nos propres satellites", les auteurs proposent les dispositions suivantes : développement de constellations de satellites, "développement de moyens de lancement très rapides de fusées emportant un satellite à partir de drones spéciaux de type ALTAIR développé par l'Onera ou de type Pegasus de Dassault", développement "de pseudo-satellites de haute altitude capables de rendre des services équivalents à un satellite de basse altitude", de type Stratobus de Thales Alenia Space ou Zephyr d'Airbus Defense & Space.
Pour mettre en place cette stratégie, le rapport propose la création d'une "Force spatiale" sous l'autorité directe du Chef d'état-major des Armées ainsi que d'une "Haute Autorité de Défense Spatiale" placée directement sous l'autorité du Premier Ministre en lien direct avec le ministre des Armées.

Joe Gould WASHINGTON ― U.S. Army officials told lawmakers Tuesday they are seeking a new 15-year, $16 billion strategy to modernize and automate the military's aging munitions plants following nearly a dozen worker deaths and injuries over recent years. In Tactical Air and Land Forces Subcommittee testimony, Army officials suggested workers who handle dangerous materials could be replaced by robotics and computers as part of their ambitious plan. The testimony came as lawmakers are deliberating over a proposed reshaping of the Pentagon's explosives oversight body, as part of the 2021 defense policy bill. “We're essentially making the explosives in a manner very much like we did in World War I in some cases, World War II in others,” Assistant Secretary of the Army for Acquisition, Logistics and Technology Bruce Jette told lawmakers. “We literally have people standing under machines that are full of 1,500 pounds of molten explosives, drooling it into artillery shells to fill them up, and then they push the carts away. We don't have automation, we don't have robotics.” Lawmakers described the ammunition industrial base as fragile because of its dependence on foreign sources of materials and because its aging facilities need of safety upgrades. (Munitions production facilities are contractor operated, with some owned by the government.) Army officials largely agreed, saying they rely on 55 foreign suppliers for certain equipment and materials ― such as a TNT-replacement 2,4-Dinitroanisole, which comes from India ― because costs, environmental regulations and legal liabilities make many of them harder to develop in the United States. The Army even relies on a small volume of detonators and pyrotechnics from China, Jette said. The Army is studying how to wean itself from foreign suppliers. At the same time, Jette has not ruled out supplies from Canada, Mexico and elsewhere, if a surge is needed, adding that he personally visited a South Korean factory that once supplied the U.S. with bullets at .50 caliber and below. Calling safety a top priority, Army officials said human handling of the energetics, explosives and acids associated with munitions can be replaced with “process automation or other technology solutions, freeing the workforce to focus on technical oversight.” More than 80 percent of major mishaps at munitions facilities were caused by human error, they said. “Three deaths in the last ten years on our facilities, two of them were related to the manufacturing process: We don't need to have that happen anymore,” Jette said. “I do not want to be the ASAALT and get another phone call that there's another death on something I could have provided the improvement to.” Jette said the 2017 death of Lake City Army Ammunition Plant worker Lawrence Bass, 55, “should not have occurred,” and that Bass ― killed while handling an explosive component called tetrazine ― was performing his duties in accordance with procedures. “His death is in fact a catalyst in transforming our approach, as opposed to modernizing under current circumstances. He should never have been in that close proximity where that event could have happened,” Jette said. “Should it happen with a machine, I can buy another machine.” Still, modernizing in the way Army officials seek would require Congress appropriate roughly $1 billion per year for 15 years, which is more than twice what the Army has asked over the last three years. It's an open question whether Congress would be as inclined to support the munitions productions facilities, if they support fewer jobs. “The idea of making it safer for workers, there's no doubt about that, but because these plants have grown up since the '40′s," said Tactical Air and Land Forces Subcommittee Chairman Donald Norcross, D-N.J. "You eliminate many of those jobs, there's potential of that support also going.” Asked what more industry could do to shoulder the cost of modernizing facilities, Jette suggested it would be better if the government made the investments upfront as industry would only pass the costs on later. “This is the United States military's industrial base for munitions. We need to own that, not have anything beholden IP-wise or any other way to the defense industry or any other supplier," Jette said. https://www.defensenews.com/congress/2020/09/22/after-munition-worker-deaths-army-floats-16-billion-plan-to-modernize-production/

by Charles Forrester Qatari pilots will soon be training at Italy's International Flight Training School (IFTS), following an agreement between the Qatar's Deputy Prime Minister and Minister of State for Defence Affairs, Dr Khalid bin Mohamed al-Attiyah, and Italy's minister of defence Lorenzo Guerini on 11 November. In a release by the Italian Ministry of Defence, Guerini said, “The partnership between Italy and Qatar in the defence sector is confirmed as having a high strategic value. I am here to renew our commitment to deepen the ongoing collaboration that embraces all sectors.” Part of the two countries' co-operation agreement would include the training of Qatar Emiri Air Force (QEAF) pilots at the IFTS, which is operated as a joint venture by Leonardo and the Italian Air Force at Lecce-Galatina, and the soon-to-be-opened facility at Decimomannu Air Base in Sardinia. Qatar currently operates the Pilatus PC-21 and PAC Super Mushshak aircraft in the training role. The country has also ordered nine BAE Systems Hawk Advanced Jet Trainers. According to Janes World Air Forces, in-country flight training is conducted at Qatar's Armed Forces Air Academy (also known as the Al Zaeem Mohammed bin Abdullah Al Attiyah Air College), established at Al Udeid in 2014. The establishment of the academy is seen as a tangible step towards bringing additional training capacity within Qatar's borders, rather than the heavy reliance upon foreign states and allies that Qatar has previously required. https://www.janes.com/defence-news/news-detail/qatar-signs-up-for-leonardos-ifts
