Missile MBDA Sea Venom : les tirs de qualif. sont achevés

Il y a une dizaine de jours, les équipes de MBDA ont réalisé le dernier tir de qualification du missile antinavire Sea Venom/ANL sur le site d'essai DGA de l'Ile du Levant.

Le missile Sea Venom/ANL qualifié

Réalisé le 17 novembre dernier, cet ultime tir de qualification du missile Sea Venom/ANL de MBDA avait pour but de valider les performances du missile en termes "de discrimination de cible en environnement naval dense et complexe". "Les essais précédents avaient permis de tester le domaine de séparation et de tir, le vol rasant à basse altitude, ainsi que les modes d'engagement du missile, tels que l'accrochage après tir (LOAL), l'accrochage avant tir (LOBL), l'opérateur dans la boucle ou encore la sélection du point d'impact", rappelle MBDA.

Premiers essais sur hélicoptère Lynx

Les premiers essais avaient commencé en 2017 sur un hélicoptère Lynx Mk 8 de la Royal Navy. Des essais d'embarquement et de largage du Sea Venom/ANL. Puis en avril 2018, avait suivi un tir depuis un hélicoptère Airbus Panther "avec vol du missile à très basse altitude et accrochage de la cible en milieu de course ». "La conduite de ce tir anti-navires a permis de mettre en lumière la capacité du missile à naviguer « au raz de l'eau (sea-skiming) et le bon fonctionnement de la liaison de données entre le missile et l'hélicoptère », avait alors précisé le Ministère des Armées. Puis, en fin d'année 2018, s'était déroulé un nouveau tir d'essai qui avait permis "de confirmer la capacité d'accrochage avant tir du Sea Venom-ANL, l'opérateur utilisant les images provenant de l'autodirecteur à infrarouge du missile pour désigner la cible avant le tir". L'essai s'est déroulé au centre d'essai de l'Ile du Levant depuis un hélicoptère d'essai Dauphin de la DGA.

Premier tir de qualif. en février dernier

Le premier tir de qualification du missile sur l'Ile du Levant au centre d'essais de missiles de la Direction générale de l'armement (DGA) a été effectué en février 2020. "Le missile a été tiré depuis un hélicoptère Dauphin de DGA Essais en vol progressant à une altitude proche de la hauteur minimale nécessaire au lancement du missile, ce dernier atteignant sa vitesse de croisière alors qu'il effectuait un vol rasant (sea-skimming). Pendant la dernière phase du vol, l'opérateur a utilisé les images provenant de l'autodirecteur à infrarouge –transmises par la liaison de données- du missile pour ajuster le point d'accrochage sur la cible. Le missile a ensuite suivi le point désigné jusqu'à atteindre la cible avec une précision extrême", indiquait alors MBDA.

Le missile antinavire Sea Venom/ANL, qui équipera bientôt les hélicoptères Wildcat AW159 de la Royal Navy et H160M Guépard de la Marine Nationale, est un programme en coopération réalisé dans le cadre du traité de Lancaster House, conclu entre la France et le Royaume-Uni, il y a eu dix ans ce mois-ci. Le Sea Venom/ANL est également le premier programme à bénéficier pleinement des centres d'excellence franco-britanniques spécialisés dans les technologies des missiles, qui ont été mis en place par le traité de Lancaster House.

    Modernization top priority in FY20 budget, Pentagon’s No. 2 official says

    By: Valerie Insinna WASHINGTON — As the Trump administration and Congress deliberate the Defense Department's top-line budget for fiscal 2020, safeguarding the military's weapons programs and funding technology development is taking precedence over growing the force, the Pentagon's No. 2 official said Thursday. “At the end of the day, the national defense strategy puts a priority on modernization,” Deputy Defense Secretary Patrick Shanahan told reporters Dec. 13. “The trick then becomes, when you talk about force structure, how much risk do you take given the world's environment?” Shanahan's comments come at a time of back-and-forth between President Donald Trump, Defense Department leadership and Congress about the size of the FY20 defense budget. Pentagon budget makers had been planning for a $733 billion budget request — a modest increase over the $716 billion budget for FY19 — when Trump announced in October that the Defense Department's budget would instead be cut to $700 billion. The move surprised many, as Trump had frequently touted his administration's efforts to grow the size of the military and invest in new defense technology. The announcement raised questions about what the Pentagon would have to cut in order to meet the lower number, but it appears that those concerns may have been premature. Earlier this week, Politico and other outlets reported that congressional Republicans and Defense Secretary Jim Mattis had convinced Trump to raise the top line to $750 billion. Shanahan on Thursday downplayed the reports, saying that a final top line had yet to be determined. "We're looking at numbers above $733 [billion], and as you know, we looked at numbers below $733 [billion]. I think everybody recognizes that this is a discussion that will go on in terms of what is the right number. The process we have is very robust,” he said. No matter what the top line ends up looking like, the goal will be “anchor[ing] line items to the National Defense Strategy. That's the rigor we put in place,” he added. With a top line above $733 billion, it's possible the Defense Department will be able to grow both its modernization accounts as well as funding for improving readiness and increasing force structure. But Shanahan, who spoke at a National Defense Industrial Association event on hypersonics on Thursday, tried to quell defense contractors' concerns that funding for hypersonic technologies, and science and technology development in general, could suffer under a budget that rings in at $733 billion or below. Asked by one Lockheed Martin employee whether funding for hypersonics programs would remain reliable in light of budgetary fluctuations, Shanahan said his level of confidence was high it would. “We've prioritized amortization,” he said. https://www.defensenews.com/congress/budget/2018/12/14/modernization-top-priority-in-fy20-budget-pentagons-no-2-official-says/

    The unlikely way to improve Air Force information warfare: forums

    Mark Pomerleau One way the Air Force's new information warfare command is trying to bring together the disparate parts of the organization is through forums where leaders put representatives from different components in the same room. Sixteenth Air Force/Air Forces Cyber, created in October, combined what was previously known as 24th and 25th Air Force. The move placed cyber, intelligence, surveillance and reconnaissance, electronic warfare and weather capabilities under one commander, serving as the Air Force's first information warfare entity. With all these new wings and capabilities now under a single unit, they need to understand what everyone is doing and how it can feed together. “How do we bring forums together where all of our wings that are focused on a problem can be in the same room and we start to build out what things are they all contributing,” Lt. Gen. Timothy Haugh, 16th Air Force's commander, told a webcast hosted by the Mitchell Institute. “Then taking it to the next layer, so all the weapons and tactics teams are talking. That simple act of creating a forum was built largely on our component responsibilities. We have very good forums ... for how do we support and produce cyber outcomes. We expanded that forum into an information warfare environment.” Some of this integration is already taking hold. Haugh explained he received a positive update earlier this month about how one meeting had led to fewer stovepipes and more data sharing. In addition, he said he'd like to see more components share intelligence as a way to enable others within the enterprise. For example, if a portion of the ISR enterprise, be it analysis or exploitation, in support of Air Forces Africa, discovers a Russian private military corporation conducting malign activities in Africa, they can pass that to the cyber enterprise to potentially pursue the adversary. Then the cyber element can feed their information or operation back to the ISR enterprise to produce better intelligence for the air component. “This is where for us, that art is starting to come together. Right now, it's very manual, and we're seeing the processes and the data flows start to fall in place that that will become a more automated and routine function that now becomes mutually supportive across our enterprise,” Haugh said. https://www.c4isrnet.com/smr/information-warfare/2020/07/22/the-unlikely-way-to-improve-air-force-information-warfare-forums/
