  Europe takes new step toward future combat jet

  France, Germany and Spain on Monday unveiled a next-generation combat jet for European air forces, an ambitious project aimed at bringing together the continent's disparate military forces while offering an alternative to American planes. The stealth jet is part of the Future Combat Air System (FCAS), which will also include drones, missiles and so-called "remote carriers" that can be used to deliver munitions, scramble communication networks or divert the attention of enemy defences. French President Emmanuel Macron attended the unwrapping of a full-scale model of the sleek delta-wing aircraft at the opening of the Paris Air Show in Le Bourget, just north of the French capital. The official cooperation accord launching the project was then signed by the French, German and Spanish defence ministers: Florence Parly, Ursula Von der Leyen and Margarita Robles. "This project now has a resolutely European dimension: Spain has officially joined the programme this morning," Parly said. Spain announced its participation earlier this year, but so far no other EU nations have signed on, though officials in Macron's office say talks are underway to bring other nations on board. Airbus and France's Dassault Aviation are leading the plane's development, aiming to have it operational by 2040, when it will replace the current generation of Rafale and Eurofighter jets. France's Safran is also developing a new motor for the plane that may include hybrid electric technologies, making the plane quieter while also lowering its heat signature, making it harder to detect. But Paris and Berlin have still to award an expected 150-million euro ($169-million) contract to begin work on a test plane that could start flying in 2026. Parly told journalists the contract is expected to be finalised by the end of this year. The new plane is a crucial test for Europe's ability to forge a joint operational command that could ensure its military sovereignty at a time of growing tensions with the US under President Donald Trump, who has put the solidity of the NATO alliance into question. Officials will have to win over several EU countries which are longstanding clients of American jets, and which may be tempted by Lockheed Martin's new F-35 stealth fighter. And the new European jet already has a rival on home turf—Britain's Tempest stealth fighter project, which has already garnered the support of Italy and the Netherlands. https://phys.org/news/2019-06-europe-future-combat-jet.html

  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

  Ground vehicles are the new frontier in Ukraine's drone war

  After the role of unmanned aerial vehicles in the Ukraine war expanded dramatically since Russia invaded 16 months ago, attention is turning to ground drones that developers say could be the next frontier in military innovation.
