  Berlin prône une consolidation du secteur de la défense européen

  JOUY-EN-JOSAS, Yvelines, 29 août (Reuters) - L'Union européenne doit renforcer les synergies en matière d'équipements militaires pour optimiser les dépenses de défense des Etats membres, ce qui passe notamment par une consolidation du secteur à l'échelle européenne, estime le ministre allemand des Finances, Olaf Scholz. Au-delà des progrès déjà enregistrés en matière de politique commune de défense et de sécurité, des mesures complémentaires sont nécessaires, déclare le vice-chancelier d'Allemagne, selon le texte d'un discours qu'il devait prononcer mercredi à l'université d'été du Medef, à Jouy-en-Josas (Yvelines). Cela passe par “une approche commune pour le matériel militaire, ce qui signifiera davantage de coopération et un processus de consolidation de l'industrie militaire européenne, y compris via des fusions”, dit-il. “Nous devons encourager les fusions pas seulement lorsqu'elles se font au bénéfice de nos propres champions nationaux”, poursuit-il. A ses yeux, cela permettra de mettre sur pied une politique de défense commune plus intégrée, à même de permettre à l'Union européenne de garantir sa sécurité mais aussi de devenir un “acteur sérieux” de l'architecture militaire mondiale. La France et l'Allemagne ont donné l'été dernier, peu après l'accession d'Emmanuel Macron à l'Elysée, un grand coup d'accélérateur à leur coopération dans le domaine de la défense en convenant de développer ensemble un avion de combat de prochaine génération, mais aussi de concevoir en commun des chars, hélicoptères et autres matériels. Toujours dans le domaine aéronautique, le bilan de l'avion de transport militaire A400M d'Airbus est pour l'instant mitigé, le programme européen ayant connu des années de dérapage des coûts, de problèmes techniques et de retards multiples. A rebours du discours volontariste du dirigeant allemand, la France semble adopter une position plus mesurée dans le projet de rapprochement auquel oeuvrent les groupes français Naval Group et italien Fincantieri. Le ministre français de l'Economie et des Finances Bruno Le Maire a assuré lors d'un déplacement à Rome au début du mois que la France et l'Italie partageait “le même désir de boucler la fusion STX-Fincantieri, qui donnera naissance à l'un des plus gros chantiers navals civils du monde”. Mais une source gouvernementale française, s'exprimant sous condition d'anonymat, avait déclaré que Naval Group (dont Thales détient 35%) ne pouvait pas être privatisé et précisé que certaines de ses activités, comme la construction de sous-marins nucléaires, constituaient des actifs stratégiques ne pouvant pas passer sous pavillon étranger.

  Active protection systems demo hits dead end for Stryker, Army evaluating next steps

  By: Jen Judson WASHINGTON — After evaluating two active protection systems in a demonstration late last fall and determining neither were the right fit for the Stryker, the Army is now evaluating how to protect one of its critical combat vehicle. “Unfortunately for Stryker, we have not found a system that is suitable for the platform,” Col. Glenn Dean, Stryker project manager told Defense News in a June 7 interview. The Army has found interim APS for both its Abrams tank and Bradley infantry fighting vehicle but has struggled to find one for Stryker. The service has moved quickly to field combat vehicle protection against rocket-propelled grenades and anti-tank guided missiles while it develops a future system. The service originally considered Herndon,Virginia-based Artis Corporation's Iron Curtain APS for Stryker, but decided in August 2018not to move forward in fielding it to Stryker units. In an effort to expand its search for an appropriate system, the Army then decided to host a demonstration in late fall last year of two additional systems: Rafael's Trophy VPS and Rheinmetall's Active Defense Systems. Signs the demonstration wasn't proving fruitful cropped up in March, when the service said they'd need extra time — an entire year — to evaluate options for Stryker. Dean said the Army was hoping they'd see promise in one of the systems at the end of the demonstration and be able to carry it through more complex characterization for better evaluation in order to make a decision. But as the demonstration wrapped up, the Army decided neither would work. “Both Rheinmetall and the medium-weight Trophy, both have maturity challenges, but the bottom line is that they turned out to not be a suitable fit for Stryker,” Dean said. “We did see some potential in systems,” Dean said, adding, “it is our desire to continue to evaluate them further so we can understand them at a greater level of detail.” Neither system received the same level of testing as Rafael's Trophy on Abrams, IMI's Iron Fist on Bradley or Iron Curtain, Dean said, and the systems could end up being the right fit for some future effort to outfit other vehicles such as the Next-Generation Combat Vehicle program's Optionally Manned Fighting Vehicle, Mobile Protected Firepower and the Armored Multipurpose Vehicle, “none of which we have identified APS solutions for yet,” Dean said. Through continued evaluation “maybe we will eventually learn something that brings us back to Stryker,” he added. Unlike Bradley and Abrams, Stryker is a relatively light-weight platform, Dean said. “It has challenges in its space, weight and power integration. It has proven difficult for us to find a system that is entirely suitable for integration.” And while no operational APS system evaluated so far seems to work for Stryker, the Army is still looking into ways to protect it as its value on the battlefield only increases with the addition of bigger guns and more expensive weapon systems. Under the Vehicle Protection System (VPS) program office, the Army is working on reactive armor improvements focused on Bradley and AMPV, but that could be of particular value for Stryker, Dean said. The Army's laser warning program that is tied to the Modular Active Protection System (MAPS) program could also contribute to Stryker protection. MAPS is a system under development with the Army featuring a common controller into which hard-kill and soft-kill protection can be plugged. And the Army will be conducting a demonstration with layered hard-kill and soft-kill protection capability later this year as part of culminating exercise for its MAPS program, according to Dean. “The soft-kill may ultimately prove to be particularly well suited for Stryker,” Dean said. Those soft-kill systems are jammers and smoke systems that help obscure and tend to take up relatively little space and are less expensive then hard-kill APS that require the reloading of countermeasures. The service is also studying what it may need for a future APS and plans to initiate a program in the late part of the next fiscal year, which could also be an opportunity to develop something more suitable for Stryker, according to Dean. While the Army does have plans to protect its combat vehicles from rockets and missiles, in a June 6 letter sent to Army Secretary Mark Esper, a group of 13 House lawmakers expressed concern the service isn't doing enough to outfit its current fleet with APS and asked the Army to explain why it hadn't requested any further funding for APS upgrades in the budget According to Dean, for Abrams and Bradley, “we are resourced to meet the requirements that we have on an urgent basis to outfit a limited number of brigades. We are doing analysis right now to support development programs of record in active protection.” He added, “What we are buying is not the end of APS activity, but it is the urgent requirements we have been given.” https://www.defensenews.com/land/2019/06/10/active-protection-systems-demo-hits-dead-end-for-stryker-army-evaluating-next-steps/

  F-35 program finishes years-late tests needed for full production

  The complex simulations at Naval Air Station Patuxent River in Maryland were meant to test how well the F-35 would perform in real-world combat scenarios.
