Une innovation québécoise à l'assaut de l'armée américaine

JEAN-FRANÇOIS CODÈRE

Le rêve d'un exosquelette qui aidera les soldats à transporter leurs lourdes charges sans se blesser approche et c'est une firme de Saint-Jean-sur-Richelieu Mawashi, qui est en pôle position d'un marché évalué à «des milliards et des milliards de dollars».

Le tiers des soldats évacués en Afghanistan ou en Irak n'avaient pas subi de «blessures de guerre», avance Alain Bujold, chef de la direction et chef de la direction technologique de Mawashi. Ils avaient plutôt subi les dommages, notamment au dos, du trop grand poids placé sur leurs épaules.

«Ça coûte 500 millions de dollars par année à l'armée américaine pour s'occuper des soldats blessés parce qu'ils transportaient trop de poids», ajoute-t-il.

Spécialiste de la recherche et de l'ingénierie pour «tout ce qui se met sur le corps humain» depuis des années, Mawashi s'est intéressée de plus près aux exosquelettes en 2013. Elle avait alors été invitée à participer à un projet de l'armée américaine, le projet Talos, qui consistait à créer une sorte d'armure à la Iron Man.

«Ils ont donné de l'argent à un paquet de compagnies, et on les a toutes clenchées», raconte fière M. Bujold.

Alléger la charge

L'exosquelette Uprise mis au point par Mawashi peut retirer jusqu'à 70% du poids transporté par un soldat de sa propre ossature. La structure épouse les formes du corps, mais n'est pas motorisée, ce qui est un avantage important selon M. Bujold, puisque les soldats peuvent ainsi être affectés à de très longues missions sans crainte d'épuiser leurs piles. Et sans avoir à transporter lesdites piles.

Une plaque posée sous le pied du soldat, dans sa chaussure, sert de fondation à l'ensemble. Cette plaque s'arrête avant les orteils, de façon à permettre au soldat de bien ressentir le sol sous ses pieds.

Des tiges métalliques articulées longent ensuite les jambes du soldat pour rejoindre une ceinture rigide. De là s'élève une «colonne vertébrale», de laquelle émergent des appendices qui permettent notamment de suspendre un sac à dos ou un plastron sans que le poids ne se dépose sur le squelette du soldat.

En situation de combat, un soldat est chargé d'en moyenne une centaine de livres d'équipement protecteur, de munitions, d'armes et d'équipements de communication, entre autres, estime M. Bujold.

«De plus en plus, les combats se déroulent dans des zones urbaines, ce qui fait qu'on ne peut utiliser de véhicules pour transporter l'équipement, ajoute-t-il. Et il y a de plus en plus de matériel pour les communications.»

«Le but n'est pas de permettre de transporter plus de poids, prévient-il toutefois. C'est de réduire les blessures et d'aider à porter ce poids.»

En avance

En mars dernier, Mawashi a été invitée par l'OTAN à venir démontrer les bénéfices que pouvait procurer Uprise à des spécialistes du déminage, qui doivent revêtir une combinaison protectrice pesant à elle seule une centaine de livres.

L'entreprise se concentre présentement à démontrer de façon claire les avantages de son produit. Elle a reçu un financement de trois ans de l'armée canadienne pour parvenir à cette fin.

«Le dernier obstacle est de prouver qu'il y a vraiment un bénéfice, indique M. Bujold. Les tests préliminaires le démontrent.»

Sur l'échelle de maturité technologique (Technology Readiness Level), qui va de 1 à 9, l'Uprise est au niveau 7. Aucune solution comparable ne le devance, selon M. Bujold, et l'Uprise est en position pour être le premier exosquelette déployé sur le terrain.

«Le premier qui va arriver avec une technologie qui fonctionne, c'est le prochain Apple, croit l'entrepreneur. On ne parle pas de millions, mais de milliards.»

C'est qu'au-delà des militaires, il y a une panoplie d'autres secteurs qui pourraient être intéressés à un exosquelette de ce genre, envisage-t-il, à commencer par l'important marché du plein air. Les pompiers, les travailleurs de la construction et les employés de chaînes d'assemblage pourraient eux aussi en bénéficier.

L'Uprise pourrait coûter de 3000$ à 20 000$, estime-t-il, selon la configuration choisie.

Jusqu'à présent, ce sont surtout des contrats de l'armée américaine qui ont permis à Mawashi d'avancer. «C'est tout récent que de recevoir du financement canadien», dit M. Bujold, qui est actionnaire à 50% de l'entreprise. L'autre moitié est détenue par Louis Bibeau, président de Logistik Unicorp, dans l'édifice de laquelle sont installés les bureaux de Mawashi.

«Il y a 99% des chances qu'on finisse par être achetés par une compagnie américaine, estime M. Bujold. C'est triste.»

«Il y a ici une mentalité de lenteur, de bureaucratie, alors qu'aux États-Unis, c'est pif, paf, maintenant.»

Le volet militaire de son entreprise n'aide pas à approcher des investisseurs québécois ou canadiens, ajoute-t-il, même si son produit « sauve des vies ». Cette tiédeur n'existe pas aux États-Unis.

    GDMS-Canada & Laflamme Aero Showcase Unmanned Helicopter at CANSEC 2019

    General Dynamics Mission Systems–Canada will showcase Laflamme Aero's LX300 Customizable Unmanned Helicopter – a Canadian-built, multi-mission and multi-role unmanned helicopter that can perform missions over land and sea – at CANSEC 2019. General Dynamics recently signed a co-operation agreement with Laflamme Aero to promote the LX300 for defence and security opportunities in Canada and internationally. The agreement will also support advances in manned-unmanned operations, autonomy, network security and human-machine collaboration in common mission management systems. “Navies and Coast Guards around the globe are seeking alternate options to manned platforms for multi-mission roles such as maritime patrol and intelligence, surveillance, and reconnaissance,” said David Ibbetson, vice president and general manager of General Dynamics Mission Systems–International. “Through this co-operation agreement with Laflamme Aero, we are pleased to move the needle on defence innovation in the process.” The LX300 is designed and built to meet helicopter certifications and standards. Its advanced tandem-rotor technology and the ability to carry 90kgs of payload will allow for sustained operations in multiple mission types. It also features aeronautical grade composite materials for blades and airframe and eliminates vibration at its source using advanced rotor technology. “The strength of this agreement lies in the complementarity of our two companies,” said Enrick Laflamme, president of Laflamme Aero. “Our helicopter, designed with aerospace standards in mind and incorporating innovative technologies, integrates seamlessly with the advanced and integrated solutions of General Dynamics to provide the best solution for the security and defence industry." http://www.canadiandefencereview.com/news?news/2678

  • Plan to buy more fighter jets puts Canada on hook for bigger share of F-35 costs

    Plan to buy more fighter jets puts Canada on hook for bigger share of F-35 costs

    Lee Berthiaume, The Canadian Press OTTAWA -- Canada is being forced to shoulder a bigger share of the costs of developing F-35 fighter jets even though it has not decided whether it will actually buy any. Canada is one of nine partner countries in the F-35 project, each of which is required to cover a portion of the stealth fighter's multibillion-dollar development costs to stay at the table. Each country pays based on the number of F-35s it's expecting to buy. Canada has pitched in more than half-a-billion dollars over the last 20 years, including $54 million last year. But that amount was based on the Stephen Harper government's plan to buy 65 new fighter jets to replace Canada's aging CF-18s, which the Trudeau government has since officially increased to 88. Even though Canada has not committed that those 88 jets will be F-35s, the Department of National Defence says that change means it will have to pay more to remain a partner -- including about $72 million this year. "Canada's costs under the F-35 (partnership agreement) are based on an intended fleet size," Defence Department spokeswoman Ashley Lemire said in an email. "Canada changed its fleet size within the F-35 (agreement) from 65 to 88 aircraft to align with government decisions on the size of the intended permanent fighter fleet to be acquired through competition and the payment increased accordingly." As each partner contribution is determined annually, based on the overall cost of the F-35 development program for that specific year, Lemire said she could not provide details how much more Canada will have to pay. The F-35's development costs have been a constant source of criticism over the life of the stealth-fighter program, which Canada first joined under the Chretien government in 1997. The entire program is believed to have already cost more than US$1 trillion. The Trudeau government says it plans to keep Canada in the F-35 development effort until a replacement for the CF-18s is chosen -- partners in the development work can buy the planes at a lower price and compete for work associated with their production and long-term maintenance. Canadian companies have so far won more than $1.2 billion in contracts related to the F-35, according to the government. The F-35 is one of four planes slated to participate in the $19-billion competition that the government plans to launch this spring, the others being Boeing's Super Hornet, Eurofighter's Typhoon and Saab's Gripen. The competition isn't scheduled to select a winner until 2021 or 2022, meaning Canada will be on the hook for several more payments. The first new aircraft is expected in 2025 and the last in 2031, when the CF-18s will be phased out. F-35 maker Lockheed Martin says more than 350 of the stealth fighters have been delivered to different countries, while Israel became the first country to use the plane in combat last year when two of the jets struck targets in neighbouring Syria. Acting U.S. defence secretary Patrick Shanahan, a former Boeing executive, nonetheless criticized the program on Monday, saying it "has room for a lot more performance." "I am biased toward performance," he was quoted as saying when asked if he is biased toward Boeing. "I am biased toward giving the taxpayer their money's worth. And the F-35, unequivocally, I can say, has a lot of opportunity for more performance." https://www.ctvnews.ca/politics/plan-to-buy-more-fighter-jets-puts-canada-on-hook-for-bigger-share-of-f-35-costs-1.4275372

    Canadian defense minister talks fighter competition and geopolitics

    By: Aaron Mehta; DefenseNews.com 20 November 2020 WASHINGTON — When the Trudeau government took office in 2015, one of the first appointments was tapping Harjit Sajjan, a combat veteran who served in Afghanistan, as Canada's minister of national defense. Sajjan is now one of the lonest-serving ministers of defense in Canadian history. After an appearance at the Halifax International Security Forum, Sajjan talked with Defense News about the country's long-awaited fighter jet procurement, as well as the nation's future on the world stage. The interview has been edited for clarity and length. Regarding the fighter competition, the plan is to either downselect to two jets in 2021, or make a final decision in 2022. Where does that decision stand? How has the coronavirus pandemic impacted the timing and size of the program? I'm very happy with the progress of the selection for our next fighter. And it's gone to a very good stage where we actually have three companies. I don't know exactly — because the team there that does the analysis is independent — which direction they'll go, of downselecting or how that's going to happen. So we'll see how the progress moves ahead. I can turn to your direct question regarding COVID-19. We initially, obviously, just like anybody, had some minor delays because we had to shift a lot of the resources to the pandemic fight. But we were able to shift our people back into dealing with our procurement very quickly because, as you know, defense is an essential service, and making sure that those jobs continue was very important to us. So the delays were actually very minor. And all the updates that I've reviewed so far [shows] that things are actually progressing extremely well. So you don't see any delays for that program likely coming as a result of COVID-19 or anything else? Right now I'm confident that we'll be able to make up any time because the shift that we made. [We have some] very good people [who] are running these very large projects, so we needed to shift some of that talent to the COVID-19 fight initially, for good reason. But in a few months, we were able to shift those people back to this program. Canada's defense budget is set to significantly increase in the coming years based on the 2017 defense policy agreement. You've recently said this will still happen, but some experts said that given the economic impact of the last year and given post-pandemic priorities, the defense budget might end up either changing or taking a cut. How confident are you that the targets that have been set are going to be hit, budget wise? First of all, the security challenges that we face around the world don't change. And that's an important point for everybody to take note of, and it's something that we took note when we conducted our defense policy review. This is one of the reasons why, when we put this defense policy together, we wanted to have a thorough cost analysis done early on based on the capabilities that we felt that we needed, not only for the defense of Canada but to be good partners as part of this financial command at North American Aerospace Defense Command or the Five Eyes [intelligence-sharing alliance] and the work that we do at NATO. So we made a decision to fund the defense policy for the duration, which is 20 years. So there was a government-level decision to do this, to carve it out of the fiscal framework, and that should give assurance to people how seriously we took this from the beginning. We looked at any type of financial challenges that a nation might go through, but we also knew that we needed to maintain the defense funding because, as you know, in the past, defense policies have been put out, but the money has not been included, and they had to be agreed upon every single year. Based on that experience, I can understand some of the concerns that some of these experts actually have, but this is something that we looked at right from the beginning, and the reason why we made a government-level decision to fund the defense policy for the 20 years. So it can't be just a very quick decision to change the defense budget. But more importantly, one of the things — probably one of the most important things that we need to take a look at, especially as we deal with COVID-19 — is the economic downturn, [is that] the defense industry adds a significant amount of well-paying jobs. So it's very important to keep these investments moving because this is about maintaining well-paying jobs across the country and supply chain that we have, connected with our allies, especially with the U.S. You mentioned global challenges. Something that recently emerged is this idea of the “Quad” between India, Japan, the United States and Australia. Do you see Canada having a role in that, and would you want to join? I can see what that initiative — what it was trying to achieve. But let's keep in mind: We already had some good mechanisms where we were working with — so for example, with the United Nations Security Council resolutions on sanctions monitoring in North Korea, that was where nations came together from all the nations that participated in the Korean conflict, Korean War early on, where we decided to up our support for [monitoring.] We created Operation NEON in Canada to provide the direct support. In fact, one of our frigates just completed their work with monitoring, and we have a surveillance aircraft still in the region conducting that work. So the work that the Quad does — I think it's extremely important. I think we need to have a much wider conversation of not just looking at the Quad, but we need to look at how allies are going to come together to look at how do we support places like the Asia-Pacific region and our Association of Southeast Asian Nations partners in the Indo-Pacific region. So I think it's a good effort, but I think we need to look at even more thorough analysis and look at what are the things that nations can contribute. There's also talk about whether to expand Five Eyes, perhaps by formally including Japan. Is the idea of a formal Five Eyes expansion something you support? First of all, Five Eyes is probably one of the most trusted agreements that we have. It's not just: “You sign an agreement, and you're part of a trusted group.” There are some very strict measures that every nation needs to take in terms of the security architecture that's needed inside your country, how we communicate — that provides a framework. That framework also includes a set of laws about governance, as well. But it does not preclude us from working with other partners, and [partners] having greater cooperation with the Five Eyes. And if ever down the road there's an opportunity, I think that's something that's to be kept on the table. But I think Five Eyes allows us to be able to work with likeminded partners, like Japan, and we're already doing some great work as it is. We'll see where the discussion goes. It seems like you're saying you're happy to work with other nations, and already do that, but that Five Eyes requires such a strict legal measure that a formal expansion might not make sense. What I'm going to say here is that there's a lot of good work already being done. When you have an expansion, that alone would require a significant amount of effort toward that. But I think right now we need to take a look at how do we use our current mechanisms to create the effects we need. Because there is a concern right now, and we need to support our ASEAN partners in the Pacific. And so it's better to look at mechanisms that we have in place and work toward a larger relationship. You've made pointed comments about China and the challenge from Beijing. Where's the greatest challenge from China for Canada? The Arctic? The Pacific? Is it economic? It's not just one thing, or pick one over another. I would say overall, the unpredictable nature that China has created, that when you go outside the international rules-based order — that was set up for good reason after the Second World War, of creating predictability — it's the unpredictability that China has created that's giving us significant concerns. So everything from freedom of navigation to how finances are used in countries to bring in influence. About the most important, the biggest one for us, is when they have a disagreement [they will] arbitrarily detain citizens. So we have two citizens who are detained. Australia just, I believe, had an incident very similar to ours. These are some of the things that cause nations around the world to take a [concerned] look. So I wouldn't say it's just one. The Arctic, I'll be honest with you, it will always be a concern for Canada because our sovereignty is extremely important to us. We want to work within partnerships under international laws. We want to do this, but a pattern that's created in other areas has caused concern for us in Canada. There's a debate among foreign policy experts over whether Canada has been too passive. Does Canada need to take a more robust foreign and national security policy stance, or are you comfortable with where it is now? I would say our stance has been misunderstood, then. If you look at the last five years alone, when we formed the government and I became defense minister, we didn't have a consistent engagement in the Pacific. Now we do. We're officially part of Operation NEON, conducting sanctions monitoring; we obviously, because of COVID-19, weren't able to do this, but we've had ships in the Pacific conducting visits, doing exercises as well, or being part of Exercise RIMPAC. And also increasing our whole-of-government approach. We put a battlegroup into Latvia that we lead, [forces] in Ukraine, we actually increased our role there, increased our footprint with the coalition to fight ISIS [the Islamic State group]. And the list goes on. We've actually commanded the NATO training mission in Iraq for the last two years. So when you look at what we do, it is quite significant. But I think in terms of — you can look at it as passive or active. We have to take a look at what does each nation bring to the table. And I remember having a conversation with [U.S. Defense Secretary Jim] Mattis about this. It's about utilizing the skill set of your closest allies and how you work together in creating effects for our diplomats. And that's exactly what Canada has been doing: being a credible partner to convene conversations to be able to move toward peaceful resolutions to disagreements. I wouldn't say that we've actually had to step back in any way. In fact, if you look at the record of what we've actually done, not only we've talked about increasing our spending, we've actually increased our capabilities and contributions at the same time.
