  Budget Busters: What to Look For in 2019 and Beyond

  By PAUL MCLEARY The release of the 2020 defense budget is still over a month away, and it's already been a wild ride. A look at what has happened, and what might happen next. WASHINGTON: If there's one complaint that has sounded a consistent across the Joint Chiefs and Pentagon leadership in recent years, it has been the lack of predictability in year-to-year funding. If there's one thing we have learned about President Trump, it's that nothing is certain until the very end. And even when there's a decision, it can be flipped, rehashed, tinkered with or forgotten about in the time it take to knock out a Tweet on phone. After two years of budget certainty in 2018-19, the 2020 submission was humming along at $733 billion — until it wasn't. In late October, the number plummeted (relatively speaking) to $700 billion, until the president was convinced by Defense Secretary Jim Mattis — not yet on his way out at the time — to rocket it up to $750 billion. But even that number isn't certain. Most analysts see the 2020 submission settling around the $733 billion level. Visiting US troops at the Al Asad air base on Dec. 26, the president gave the latest vague update. “I mean, I want to see costs come down, too. But not when it comes to our military. You have to have the finest equipment anywhere in the world, and you have that — $716 billion. And this year, again, we're going to be — don't tell anybody because nobody else knows — even a little bit higher.” Whatever the number is, it appears likely that incoming acting Defense Secretary Patrick Shanahan will be the one to deliver and defend it on Capitol Hill in February, as Mattis has been told to leave by Jan. 1. It's unclear what effect the firing of Mattis will have on the process, or if there will be any significant strategic shifts for the department given the change in leadership. As budget guru Todd Harrison of the Center for Strategic and International Studies told me this week — specifically in reference to the Space Force, but it really applies across the entire budget — “the thing to keep in mind is that this is, so far, just the Pentagon's proposal to the White House. It's not clear if the White House is going to agree to this. The president has a way of sticking to his ideas even if his own administration recommends otherwise.” Here are a few of the stories we've done over the past months breaking down what is happening, and what might — might — happen next.

  Dépenses militaires mondiales toujours en hausse, le Canada à un record historique

  Selon les nouveaux chiffres du Stockholm International Peace Research Institute (SIPRI), le total des dépenses militaires mondiales a atteint 1 739 milliards $US en 2017, une augmentation de 1,1 % en termes réels par rapport à 2016. L'organisation explique dans son rapport que les dépenses militaires de la Chine ont de nouveau augmenté en 2017, poursuivant une tendance à la hausse des dépenses qui dure depuis plus de deux décennies. Les dépenses militaires de la Russie ont diminué pour la première fois depuis 1998, tandis que les dépenses des États-Unis sont restées constantes pour la deuxième année consécutive. En 2017, les dépenses militaires représentent 2,2 % du produit intérieur brut mondial (PIB) soit 230 $US par personne. «L'augmentation des dépenses militaires mondiales de ces dernières années est largement dues à la croissance substantielle des dépenses des pays d'Asie et Océanie et du Moyen-Orient, tels que la Chine, l'Inde et l'Arabie Saoudite», précise Dr Nan Tian, chercheur au programme Armes et Dépenses militaires (AMEX) du SIPRI. «Au niveau mondial, le poids des dépenses militaires s'éloigne clairement de la région Euro-Atlantique». Dans le détail Les dépenses militaires en Asie et Océanie ont augmenté pour la 29ème année consécutive. La Chine, deuxième plus grand dépensier au monde, a augmenté ses dépenses militaires de 5,6 % à 228 milliards $US en 2017. La part des dépenses chinoises dans les dépenses militaires mondiales est passée de 5,8 % en 2008 à 13 % en 2017. En revanche, les dépenses militaires en Afrique ont diminué de 0,5 % en 2017, soit la troisième baisse annuelle consécutive depuis le pic des dépenses enregistré en 2014. Avec 66,3 milliards $US, en 2017 les dépenses militaires de la Russie sont inférieures de 20 % à celles de 2016, première baisse annuelle depuis 1998. Poussées, en partie, par la perception d'une menace croissante de la part de la Russie, les dépenses militaires en Europe centrale et occidentale ont augmenté respectivement de 12 % et 1,7 %. De nombreux États européens sont membres de l'Organisation du Traité de l'Atlantique Nord (OTAN) et, dans ce cadre, ont convenu d'augmenter leurs dépenses militaires. Le Canada n'est pas en reste puisque pour la première fois le pays intègre le Top 15 mondial (14e place) avec plus de 27 milliards $ CAD dépensés en Défense, comparativement à environ 24 milliards $ CAD en 2016. C'est donc une hausse de 15% en une seule année ! Dans une déclaration envoyée à 45eNord.ca, le ministre de la Défense nationale Harjit Sajjan indique: «Nous respectons notre engagement d'accroître les dépenses de défense gr'ce à notre politique de défense nationale, Protection, Sécurité, Engagement. Tel qu'énoncé dans notre politique de défense, nous augmentons les dépenses annuelles de défense au cours des 10 prochaines années pour les porter à 32,7 milliards de dollars en 2026-27, soit une augmentation de plus de 70%. Je suis fier des investissements historiques que notre gouvernement réalise gr'ce à Protection, Sécurité, Engagement, et le Canada est fier d'être parmi les meilleurs pays qui investissent dans ses forces armées». http://www.45enord.ca/2018/05/depenses-militaires-mondiales-hausse-sipri-canada-record-historique/

  How the Office of Naval Research hopes to revolutionize manufacturing

  By: Daniel Cebul WASHINGTON — The Office of Naval Research awarded Lockheed Martin Oct. 1 a two-year, $5.8 million contract to explore how machine learning and artificial intelligence can make complex 3-D printing more reliable and save hours of tedious post-production inspections. In today's factories, 3-D printing parts requires persistent monitoring by specialists to ensure intricate parts are produced without impurities and imperfections that can compromise the integrity of the part overall. To improve this laborious process, the Navy is tasking Lockheed Martin with developing multi-axis robots that use lasers to deposit material and oversee the printing of parts. Lockheed Martin has multiple partners on the contract including Carnegie Mellon University, Iowa State University, Colorado School of Mines, America Makes, GKN and Wolf Robotics and Oak Ridge National Laboratory. The contract covers what Glynn Adams, a senior engineer with Lockheed Martin, describes as the pre-flight model of the program's development. Initial work will focus on developing computer models that can predict the microstructures and mechanical properties of 3-D printed materials to generate simulation data to train with. Adams said the Carnegie Mellon team will look at variables such as, “the spot size of the laser beam, the rate of feed of the titanium wire [and]the total amount energy density input into the material while it is being manufactured.” This information helps the team predict the microstructure, or organizational structure of a material on a very small scale, that influences the physical properties of the additive manufactured part. This data will then be shared with Iowa State, who will plug the information into a model that predicts the mechanical properties of the printed component. By taking temperature and spot size measurements, the team can also ensure they are, “accurately controlling energy density, the power of both the laser and the hot wire that goes into the process,” Adams said.. “All of that is happening before you actually try to do any kind of machine learning or artificial neural networks with the robot itself. That's just to try to train the models to the point where we have confidence in the models,” Adams said. Sounds easy, right? But one key problem could come in cleaning up the data and removing excess noise from the measurements. “Thermal measurements are pretty easy and not data intensive, but when you start looking at optical measurements you can collect just an enormous amount of data that is difficult to manage,” Adams explained. Lockheed Martin wants to learn how shrink the size of that dataset without sacrificing key parameters. The Colorado School of Mines and America Makes will tackle the problem of compressing and manipulating this data to extract the key information needed to train the algorithms. After this work has been completed, the algorithms then will be sent to Oak Ridge National Laboratory, where robots will begin producing 3-D titanium parts and learn how to reliably construct geometrically and structurally sound parts. This portion of the program will confront challenges from the additive manufacturing and AI components of the project. On the additive manufacturing side, the team will work with new manufacturing process, “trying to understand exactly what the primary, secondary and tertiary interactions are between all those different process parameters,” Adams said. “If you think about it, as you are building the part depending on the geometric complexity, now those interactions change based on the path the robot has to take to manufacture that part. One of the biggest challenges is going to be to understand exactly which of those parameters are the primary, which are the tertiary and to what level of control we need to be able to manipulate or control those process parameters in order to generate the confidence in the parts that we want.” At the same time, researchers also will tackle AI machine learning challenges. Like with other AI programs, it's crucial the algorithm is learning the right information, the right way. The models will give the algorithms a good starting point, but Adams said this will be an iterative process that depends on the algorithm's ability to self-correct. “At some point, there are some inaccuracies that could come into that model,” Adams explained. “So now, the system itself has to understand it may be getting into a regime that is not going to produce the mechanical properties or microstructures that you want, and be able to self-correct to make certain that instead of going into that regime it goes into a regime that produces the geometric part that you want.” With a complete algorithm that can be trusted to produce structurally sound 3-D printed parts, time-consuming post-production inspections will become a thing of the past. Instead of nondestructive inspections and evaluations, if you “have enough control on the process, enough in situ measurements, enough models to show that that process and the robot performed exactly as you thought it would, and produced a part that you know what its capabilities are going to be, you can immediately deploy that part,” said Adams. “That's the end game, that's what we're trying to get to, is to build the quality into the part instead of inspecting it in afterwards." Confidence in 3-D printed parts could have dramatic consequences for soldiers are across the services. As opposed to waiting for replacement parts, service members could readily search a database of components, find the part they need and have a replacement they can trust in hours rather than days or weeks. “When you can trust a robotic system to make a quality part, that opens the door to who can build usable parts and where you build them,” said Zach Loftus, Lockheed Martin Fellow for additive manufacturing. “Think about sustainment and how a maintainer can print a replacement part at sea, or a mechanic print a replacement part for a truck deep in the desert. This takes 3-D printing to the next, big step of deployment.” https://www.c4isrnet.com/industry/2018/10/15/how-the-office-of-naval-research-hopes-to-revolutionize-manufacturing
