Thales et Airbus vont moderniser les outils de collecte de renseignements électroniques des armées françaises

Les trois armées (air et espace, terre, mer) françaises disposeront bientôt de moyens de collecte de renseignements électroniques unifiés, fournis par Thales et Airbus.

En matière de collecte de renseignements électroniques, les différentes armées françaises disposaient chacune de leurs propres technologies. Ce sera bientôt de l'histoire ancienne. La DGA (Direction générale de l'armement) a chargé fin 2020 Airbus et Thales de lui fournir des capacités de recueil du renseignement d'origine électromagnétique (ROEM) unifiées. Un contrat d'une durée de dix ans, dont le montant total n'a pas été communiqué.

Dans les années à venir, les trois armées (de l'air, de terre et marine nationale) disposeront toutes du même type de capteurs, matériels et logiciels pour capter les communications de leurs adversaires sur les différents thé'tres d'opérations. De quoi améliorer leurs capacités en matière d'écoute, de radiogoniométrie (qui permet de localiser une émission hostile, radar ou radio par exemple) et d'exploitation du spectre électromagnétique, gr'ce à des technologies de dernière génération. Cette unification permettra aussi aux différents corps de mieux se coordonner. La formation des spécialistes en sera, enfin, facilitée. La DGA a passé une première commande fin 2020 pour 160 millions d'euros de matériels et logiciels, qui seront livrés à partir de 2023.

Rester au niveau dans la guerre électronique

Le système interarmées ROEM tactique sera utilisé sur des véhicules Scorpion en remplacement des équipements tactiques actuels, sur les navires de premier rang de la marine nationale et les avions de patrouille maritime Atlantique 2, et pour la protection de bases aériennes. Airbus et Thales fournissaient déjà certaines briques technologiques de l'arsenal déployé par la France dans la guerre électronique. Le second avait développé le programme Cohorte (système actuel de ROEM tactique utilisé par l'armée de terre), le premier le programme Ramses (Evolution du système d'information stratégique traitant des communications radio et satellite).

    To build stockpiles of weapons, UK looks at two-pronged approach

    By: Aaron Mehta WASHINGTON — When the U.K. rolled out its Modernising Defence Programme report last month, it highlighted a need to increase stores of weaponry to deal with threats from great powers around the globe. In his speech unveiling the document, Defence Secretary Gavin Williamson specifically stated that to “improve the combat effectiveness of our forces, we will re-prioritize the current defense program to increase weapon stockpiles. And we are accelerating work to assure the resilience of our defense systems and capabilities.” But what does that actually entail? During a Tuesday visit to Washington, Director for Strategic Planning Will Jessett said the U.K. plans to go about increasing weapon stockpiles in two ways. The first is the easy route: throw money at the problem. And a certain amount — the Ministry of Defence employee wouldn't say exactly how much — of the recent budget increase given by Parliament will indeed be going toward increasing stockpiles of armaments. The second part is more difficult, but goes to a throughline for the strategy document: the need to be smarter about how the British military uses its gear. “We've spend a shedload of money on producing the force structure that we have already. We're not necessarily generating and using it as effectively as we might have done,” Jessett said. “The first thing to do is to make sure that we are making the best of the existing capability that we have, and that [includes] making sure that we've got both the weapon stockpiles and the spares to make sure that you can actual[ly] generate the right numbers of aircraft squadrons." “So some of this will be the new money out of the couple of billion but a lot of this is going to be telling the services themselves,” he added. “There isn't a dollar figure, but there are strong incentives now back on the services to say: ‘Guys, you've got to [use] the capabilities that you've got already.' ” Looking at the Pentagon's efforts over the last few years shows that may be easier said than done. Pushing to find new efficiencies inside the U.S. Defense Department is an annual affair, with the latest attempt delayed by the removal of Chief Management Officer Jay Gibson and the fallout from the resignation of Defense Secretary Jim Mattis. And building up missile stockpiles is a logistical challenge for the department right now, with the Pentagon warning last May that producers of vital parts and materials are on the verge of going out of business or beholden to foreign ownership. Jessett acknowledged the Brexit-shaped elephant in the room, noting that the ability of the MoD to invest funding into new defense priorities will be directly impacted by any deal reached between Britain and the rest of Europe, particularly with foreign-made equipment. “Amongst the reasons we started to face this affordability delta in 2017 were because exchange rates did fall, relative to where they were in 2015,” he said. “I think back to this [question] about the terms of the deal. If we get a deal that's OK, I can imagine, personally, exchange rates not just stabilizing but somewhat improving. If not, it is by definition going to add further pressure into this.” But, he added, “that's not what we're planning for at the moment.” https://www.defensenews.com/global/europe/2019/01/08/to-build-stockpiles-of-weapons-uk-looking-at-two-pronged-approach

    Arms industry eyes boost as Europe looks to bolster defences

    Russia's invasion of Ukraine has catapulted defence spending up the political agenda in Europe and could herald a new era of purchases led by Germany, according to weapons makers gathering at an arms fair in Saudi Arabia this week.

    Deputy Secretary General reiterates NATO’s commitment to responsible innovation in defence and security

    NATO Deputy Secretary General Mircea Geoană addressed the Responsible Innovation Defence and Security Conference in Brussels on 27 November 2023 and thanked Belgium, the Netherlands and Luxembourg for organising the event, together with the NATO Emerging Security Challenges Division. He said that new technologies can transform our lives for the better in countless ways, but like any new technology, they bring risks, including to our security. Mr Geoană said that it is vital to develop these technologies responsibly and respecting our values - freedom, democracy, human rights and the rule of law.
