    UK hits pause on defense review due to coronavirus

    By: Andrew Chuter LONDON — The British government has hit the pause button on its integrated defense review as it pours its efforts into battling the coronavirus crisis, Cabinet Office officials have told the parliamentary Defence Committee. “The Cabinet Office has informed the defence select committee that work on the integrated review has been formally paused across Whitehall,” the committee announced April 15. Committee chair Tobias Ellwood said in a statement that the move by the Cabinet Office, the department leading the review, was the right move to take given the crisis. “There would be no point in conducting an in-depth review of the nation's defence and security challenges to an artificial deadline, especially at a time when Whitehall is rightly focusing on tackling conronavirus,” Ellwood said. The recently appointed Defence Committee chair said that when the review restarts it will have to do so “with the added consequences of the pandemic to be considered.” A spokesperson for the Defence Committee said the Cabinet Office had not given any indication as to when it might start to ramp up the review effort again. However, two sources tell Defense News that the review could go on ice for up to a year. In a letter announcing the pause, deputy national security adviser Alex Ellis said that while the review was on hold, the government would be retaining a “small core capacity to think about the long-term effects of COVID-19 and issues expected to be covered in the Integrated Review." This team will be very limited in size and function, he added. The Ministry of Defence already faced mounting budget problems before the pandemic struck. Now, the massive economic crisis facing the British government makes it highly unlikely any additional cash will be found for defense, despite the prominent role the military is playing here combating the virus. The review was initiated immediately following Boris Johnson's election as prime minister in early December. Johnson promised it would be the most fundamental review of its kind since the end of the Cold War. Defense, security, foreign policy and international development strategy were to all be part of the effort. The review was scheduled by the government to be completed by July, a timescale the Defence Committee, analysts, lawmakers and others all said was too quick. Johnson first signaled his intention to slow down work on the review in a letter to Ellwood and two other committee chair dated March 24. “We have diverted resources from across Government and the Civil Service to work on COVID-19, scaling back efforts on the Integrated Review,” Johnson said at the time. Quizzed last month by parliamentarians about a possible delay to the review, Defence Secretary Ben Wallace said the government was open-minded about putting the work on hold. “There is no ideological block or determination to carry on come what may," Wallace said then. “With this coronavirus growing, if it is the right thing to do, we will absolutely pause the review if necessary; if not, we shall move forward.” Jon Louth, an independent defense analyst, believes the government may have to start the review process over again, given the changing circumstances. “I think we are close to going back to square one, if the budget settlement for defense is to be unpicked and secured as part of a late Autumn or Spring [2021] government-wide spending review,” he said. “Who could have any confidence in what the defense equipment program funding settlement would actually be? It could involve unpacking current contracts, but also unpick some of the ambition we have in terms of new things. “What we have and what we would like are going to be colored by a budget settlement smaller than people were anticipating; in fact, quite substantially smaller. Whether that means the MoD starts to think about reprofiling things to the right or really starts taking strategic choices, we will have to wait and see,” added Louth, who until recently was a senior analyst at the Royal United Services Institute think tank in London. https://www.defensenews.com/global/europe/2020/04/15/uk-hits-pause-on-defense-review-due-to-coronavirus/

    SCAF : la connectivité des systèmes sera assurée par Airbus et Thales

    Airbus et Thales ont signé un accord afin de mener conjointement le développement de l'Air Combat Cloud du SCAF. Qui dit système de systèmes, dit connectivité. En effet, le SCAF rime avec combat collaboratif et échange de données entre les différentes plateformes intégrées. Airbus et Thales ont donc signé un accord le 20 février, officialisant leur collaboration sur le volet Air Combat Cloud du SCAF. Une première phase de démonstrations sera conduite au cours des 18 prochains mois, dans le cadre du contrat Phase 1A du SCAF. Les travaux qui seront réalisés lors de cette première étape serviront de base aux développements futurs. Données. Un travail important attend donc désormais les deux industriels, au regard de l'avancée technologique qui caractérise les vecteurs du SCAF. Que ce soit le NGF (nex generation fighter), les remote carriers (drones d'accompagnement) mais également toutes les plateformes d'ores et déjà existantes, ces aéronefs collectent une quantité de plus en plus importante de données. Celles-ci doivent être triées, traitées et analysées, afin de fournir une information enrichie aux opérationnels et les aider dans leur prise de décision. « Au sein du SCAF, l'Air Combat Cloud va, en temps réel, connecter et synchroniser toutes les plateformes et permettre de traiter et distribuer l'information afin d'améliorer la connaissance situationnelle et permettre la conduite d'opérations en collaboration », détaille Thales. https://www.air-cosmos.com/article/scaf-la-connectivit-des-systmes-sera-assure-par-airbus-et-thales-22622

    What’s so sweet about sugar cube-sized robots?

    By: Kelsey D. Atherton If there is anything the future is lacking, it's robots the size of Chiclets. Draper, working under a grant from the Defense Advanced Research Projects Agency, is creating centimeter-sized robots, for future use in rescue work. The project is named “SHort-Range Independent Microrobotic Platforms,” or “SHRIMP” for short. And short is the nature of the game. SHRIMP is based on the 4 cm long, 1.5 g Harvard Ambulatory MicroRobot (HAMR), and wants to shrink it down to a single cubic centimeter. That will require microelectromechanical systems, 3D printing, piezoelectric actuators and, this is crucial, low-power sensors. Once all of that is in place, Draper claims the microbot will be able to jump, sense, navigate and control itself. The design will rely on feet inspired by living creatures to give it extra friction on rough and vertical terrain, and inertial measurement to detect where it is on the ground. “The microrobotic platform capabilities enabled by SHRIMP will provide the DoD with significantly more access and capability to operate in small spaces that are practically inaccessible to today's state-of-the-art robotic platforms,” declared DARPA in the proposer's day note. “Such capability will have impact in search and rescue, disaster relief, infrastructure inspection, and equipment maintenance, among other operations.” The exact “how” of what these robots will do in disaster relief, inspection, maintenance or other operations is yet to be determined, and will largely hinge on the sensors that can be fit to the platform. The most useful thing a small robot can do is get into a space and send information back to humans about that space, but that's hardly the only metric to evaluate the platform. As part of the SHRIMP program, DARPA will have the robot designs compete through a series of events modeled after the Olympics. These include high jump, long jump, weightlifting, shot put, tug of war, rock piling, steeplechase, biathlon, vertical ascent — all ways to find out what useful tasks tiny robots can do. There's a world of speculation between a dime-sized robot that can pile rocks and a useful military tool, but the fact that DARPA is invested in the technology as a platform suggests that, should the technology get there, the design will have some unexpected utility. In the meantime, DARPA's interest suggests there's good odds on a future market for sensors designed for dice-sized robots. https://www.c4isrnet.com/unmanned/robotics/2019/06/12/what-does-darpa-want-with-sugarcube-sized-robots/
