    Pour la présidente de la commission de la défense de l’Assemblée nationale, «le budget de la défense doit être, plus que jamais, préservé»

    Françoise Dumas, présidente de la commission de la défense de l'Assemblée nationale, souligne, dans une tribune au Figaro, que l'industrie française de la défense constitue un outil précieux pour relancer l'économie française. «Un plan de relance à la hauteur des enjeux doit (...) surtout donner un stimulus immédiat à notre économie. Voilà qui plaide pour un focus très puissant en faveur de la défense et, par extension, de l'aéronautique et de l'espace, qui lui sont intrinsèquement liés», déclare notamment Mme Dumas. «L'industrie de défense, l'aéronautique et l'espace sont les grands points forts de la France dans la concurrence internationale. Il faut défendre nos atouts existants, en reprenant le travail lorsque toutes les précautions sanitaires seront réunies et, d'autre part, en préservant nos industries stratégiques de la récession qui frappe le reste de notre économie», poursuit-elle, mettant en garde contre d'éventuelles «coupes budgétaires destructrices dans l'exécution ou dans l'actualisation de la loi de programmation militaire» votée pour les années 2019 à 2025. «Investir dans la défense, c'est ainsi créer des emplois, de la valeur ajoutée et de l'innovation technologique dès à présent ; c'est relancer tout de suite, et non pas plusieurs années plus tard. Ne nous privons pas d'un vecteur de relance plus réactif que les autres», conclut Mme Dumas. Le Figaro du 6 mai

    Faulty $5 Parts Cause 18-Month, $1 Billion Delay to Navy, Air Force Nuclear Upgrades

    Defects found in a $5 electrical component will delay the Navy and Air Force nuclear warhead refurbishment program by 18 months and cost more than $1 billion to fix, a National Nuclear Security Administration official said during a congressional hearing Wednesday. The faulty components are small commercially available capacitors that were to be used in upgrades to the Navy's W88 nuclear warheads. These weapons are deployed on the Trident II D5 submarine-launched ballistic missile systems. Similar capacitors are needed to upgrade the Air Force's B61-12 gravity bomb, Charles Verdon, deputy administrator for defense programs at the National Nuclear Security Administration, told members of the House Armed Services subcommittee on strategic forces during the unclassified portion of Wednesday's hearing. When engineers evaluated available parts, they ran tests to determine if the off-the-shelf capacitors were compatible with the systems due for upgrades, Verdon said. Initial results suggested the components would work in the short-term. “Early tests on the capacitors now in question and subsequent tests including component, major assembly and full-up integrated system flight tests demonstrated that these components meet requirement today. Industry best practices were used to stress the components beyond their design planned usage as a way to establish confidence that they will continue to work over the necessary lifetime of the warhead,” Verdon said. “During stress testing, a few of these commercially available capacitors did not meet the reliability requirements.” The problem is, these parts used in the warhead upgrades must survive for decades, up to 30 years after production, Verdon said. However, the quality of each capacitor production lot varied, which led to the stress testing failure. Instead of using the capacitors and risking readiness in the future, Verdon said his agency decided to delay the upgrade work, initially scheduled to begin in December. Replacement capacitors are being produced but will cost about $75 per unit, compared with the $5 per unit cost of the off-the-shelf capacitors that failed stress testing. “The use of commercial-off-the-shelf electric components needs to be improved to reduce future COTS-related risk,” Verdon said. The Navy is working with U.S. Strategic Command to understand how the 18-month delay will affect near-term deployments, Vice Adm. Johnny Wolfe, the director of strategic systems programs for the Navy, told the panel. “Currently, today, based on what we're doing with STRATCOM, we will meet the requirements as we move forward,” Wolfe said. The Navy and STRATCOM are developing a mitigation plan which includes is reevaluating how to turn around the submarine-based nuclear missile stockpile and how to schedule warheads for upgrades in the future, Wolfe said. More details on the Navy's plan to be discussed in a classified hearing. “If you look at the age of these systems and the technology we're using, these are tough, tough issues to solve, and it's critical technology that we're learning as we modernize these,” Wolfe said. Rep. Jim Cooper (D-Tenn.), chair of the strategic forces subcommittee, said he held the hearing because he wanted more information on what NNSA was doing to avoid more delays. He called the recapitalization “both necessary and hugely expensive” in his written opening statement. “Maintaining Congress and the public's confidence in these programs, and their effective execution, is imperative,” he wrote. https://news.usni.org/2019/09/25/faulty-5-parts-cause-18-month-1-billion-delay-to-navy-air-force-nuclear-upgrades
