    The Army and Marine Corps are looking at what troops will need to fight in megacities, underground

    By: Todd South A recent Army and Marine war game that included engineers, academics and other defense representatives evaluated how troops could use experimental technologies to fight in dense urban areas and underground. The U.S. Army Subterranean and Dense Urban Environment Materiel Developer Community of Practice is a working group that has conducted three prior workshops that set the challenges of fighting in those environments. “Fighting in dense urban environments and the unique challenges it presents is still not totally understood, and this study was the front-end look at identifying and defining those materiel challenges to drive where investments need to be for this operational environment,” said Bob Hesse, technical lead coordinator for the Community of Practice. The most recent “tabletop” exercise looked at the gear troops might need to get through those intense battle scenarios, according to an Army release. Soldiers and Marines worked as friendly and enemy forces during the exercise, evaluating 48 experimental future technologies. One such piece of tech would be using sensors that attach to the exterior building wall to help troops visualize the interior layout. And every advantage in these terrains can help. “Everything that Marine formations or Army formations have to do is more difficult when you take it into an urban environment,” explained Marine Corps Brig. Gen. Christian Wortman, commanding general of the Marine Corps Warfighting Laboratory, and vice chief of Naval Research. The Marines recently launched Project Metropolis II, a five-year effort to better prepare Marines for likely future urban battles. “Across the warfighting functions — whether it's intelligence, surveillance or reconnaissance, collections, maneuver, force protection, command and control, logistics and sustainment — all of those things are complicated and challenged by the compartmentalized terrain that's present in the urban environment and the three-dimensional nature of the urban environment,” Wortman said. And that multi-dimension challenge grows with the subterranean. For both above ground and underground, robotics will play a major role. The Squad X project by Defense Advanced Research Projects Agency, for example, is blending robots into dismounted formations. Soldiers with the 10th Mountain Division and 101st Airborne Division along with Marines at Camp Lejeune, North Carolina, are experimenting with four submissions for the Squad Multipurpose Equipment Transport gear mule that will carry fuel, water, ammunition and equipment for a squad through rough terrain over 60 miles on a 72-hour mission. Lt. Col. Calvin Kroeger, battalion commander for the 35th Engineering Battalion, ran one of the blue teams during the tabletop exercise. Participants ran scenarios such as a high-intensity fight, a traditional counter-insurgency and a security force-assisted mission, all under the conditions of a megacity. But the wargaming went beyond simply clearing buildings and attacking objectives. Teams countered enemy social media campaigns, communicated underground, and assessed the second- and third-order effects of engaging the enemy with lethal munitions, which could impact local power, gas and water networks. “How we employ our capabilities changes as you move from a high-rise platform to urban cannons,” Kroeger explained. “But you're also looking at everything under the ground as well, where you can't use a conventional means like a mortar system to shape the battlefield, so that the enemy doesn't shape it for you.” As team members fix on what materiel needs might best serve troops, Hesse said the subject matter experts will assess how well the tech will meet military goals. For example, if there is an aerial technology that might help troops locate enemy forces, even though the troops can't see them because of the skyline, his team would then analyze that technology and determine how well it meets Army standards and if it needs to be modified. “We will now transition from the workshop learning to live experiments and replicate the unique conditions in real venues. We're taking the materiel campaign of learning and now transforming that into action,” Hesse said. https://www.armytimes.com/news/your-army/2019/01/09/the-army-and-marine-corps-are-looking-at-what-troops-will-need-to-fight-in-megacities-underground/

    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. https://www.air-cosmos.com/article/missile-mbda-sea-venom-les-tirs-de-qualif-sont-achevs-23912

    Army Expects Major Competition for Bradley Fighting Vehicle Replacement

    The deputy commander of Army Futures Command told lawmakers recently that he expects the competition to replace the Bradley Fighting Vehicle to be highly competitive. The Army recently released the request for proposal (RFP) for the Next Generation Combat Vehicle-Optional Manned Vehicle (NGCV-OMFV), the second-highest priority in the service's new modernization strategy. The new vehicle will be designed to maneuver a squad of soldiers through dense urban terrain as well as wooded areas and deliver "decisive lethality" in close combat against a near-peer foe such as Russia, according to the RFP the Army released in late March https://www.military.com/daily-news/2019/04/03/army-expects-major-competition-bradley-fighting-vehicle-replacement.html
