Le gouvernement du Canada annonce les propositions retenues dans le cadre du Programme de science et technologie pour la connaissance de la situation dans tous les domaines

Le 20 octobre 2017 – Ottawa

Le Programme de science et technologie pour la connaissance de la situation dans tous les domaines (CSTD) appuiera l'élaboration d'options, sur une période de cinq ans, pour améliorer la connaissance de la situation des voies d'approche aériennes, maritimes de surface et sous-marines du territoire canadien, particulièrement dans l'Arctique.

Les solutions de surveillance examinées et retenues dans le cadre du Programme de science et technologie pour la CSTD renforceront la capacité du gouvernement du Canada à exercer sa souveraineté dans le Nord et offriront une meilleure connaissance des questions de sûreté et de sécurité ainsi que des activités commerciales et de transport dans l'Arctique canadien.

Les contributions du Canada à la sécurité de la région arctique font également partie des relations canado-américaines en matière de défense. Ce n'est nulle part aussi apparent que dans les efforts concertés pour renouveler le Système d'alerte du Nord (SAN) et moderniser des éléments du Commandement de la défense aérospatiale de l'Amérique du Nord (NORAD). À mesure qu'évoluent les questions de sécurité dans l'Arctique, le Canada et les États-Unis continuent de travailler côte à côte pour sécuriser nos voies d'approche aériennes et maritimes communes.

Le Système d'alerte du Nord (SAN) est une chaîne de stations radars sans personnel dans l'Arctique canadien, qui assure une surveillance aérospatiale des voies d'approche nordiques au Canada et aux États-Unis.

Alors que le SAN actuel arrive à la fin de sa durée de vie utile du point de vue technologique et fonctionnel, l'ensemble des menaces potentielles pour le continent, comme celles que posent les missiles de croisière, est devenu de plus en plus complexe et difficile à détecter.

C'est pourquoi le Canada et les États-Unis ont mis en place une collaboration bilatérale dans la recherche de solutions technologiques novatrices aux défis à la sécurité du continent, y compris l'alerte lointaine. Des études sont en cours pour déterminer la meilleure façon de remplacer cette importante capacité dans le cadre de la modernisation générale du NORAD.

Le Programme de science et technologie pour la CSTD fait partie de cette collaboration bilatérale.

Voici les propositions retenues à la suite du premier appel de propositions :

Titre : Acoustic Source for Ocean Propagation Experimentation
Fournisseur : GeoSpectrum Technologies Inc.
Lieu : Dartmouth (Nouvelle-Écosse)
Domaine : Surveillance sous-marine
Type de projet : Démonstration technologique
Financement : 4 953 038 $ (jusqu'au 31 mars 2020)

GeoSpectrum Technologies Inc. s'est vu attribuer un contrat pour concevoir, élaborer, construire et tester une source acoustique qui servira à des expériences scientifiques sur la propagation sonore sous-marine. Un tel mécanisme pourrait faire partie de futurs systèmes capables d'assurer des communications sous-marines sur de longues distances; par exemple, dans un véhicule sous-marin sans pilote engagé dans des travaux d'arpentage en pleine mer ou sous la glace.

Titre : Acoustic Array for Persistent Under-Ice Vehicles
Fournisseur : GeoSpectrum Technologies Inc.
Lieu : Dartmouth (Nouvelle-Écosse)
Domaine : Surveillance sous-marine
Type de projet : Recherche et développement
Financement : 1 944 175 $ (jusqu'au 20 septembre 2019)

Le but de ce projet est de concevoir et construire un réseau de capteurs adapté au tractage par véhicule sous-marin autonome. La conception innovante, qui utilise un c'ble semblable à une ligne de pêche avec des capteurs acoustiques, peut convenir à des opérations sous l'eau ou sous la glace à longueur d'année, dans l'environnement hostile des eaux arctiques.

Titre : Development of the Canadian High Arctic Ionospheric Models (CHAIM)
Fournisseur : Université du Nouveau-Brunswick
Lieu : Fredericton (Nouveau-Brunswick)
Domaine : Surveillance aérienne
Type de projet : Recherche et développement
Financement : 1 165 143 $ (jusqu'au 31 mars 2020)

Les modèles ionosphériques actuels utilisés dans la prévision de la propagation des ondes radio pour les communications et d'autres applications, présentent des lacunes importantes dans les régions arctiques. Cela est dû à des inexactitudes et au manque d'observations ionosphériques locales. Ce projet vise à améliorer la situation en produisant des modèles de densité électronique à latitude élevée et à des altitudes variant de 100 à 3000 kilomètres.

Titre : Bistatic High Elevation Long Endurance (HALE) Unmanned Air System (UAS) Scenario Study
Fournisseur : C-CORE
Lieu : Ottawa (Ontario)
Domaine : Surveillance de surface
Type de projet : Étude
Financement : 221 000 $ (jusqu'au 31 juillet 2018)

Ce projet consiste en l'étude des capacités potentielles de l'utilisation d'un système aérien sans pilote à haute altitude et longue endurance (HALE) comme récepteur dans une configuration bistatique pour les missions actuelles et futures avec radar à synthèse d'ouverture (RSO) commercial. L'étude examinera comment diverses configurations d'émetteurs et les récepteurs montés sur un système aérien sans pilote HALE peuvent augmenter les capacités présentes de détection et discrimination, tout en fournissant un moyen de surveillance en tout temps, à grande mobilité et persistant, qui n'existe pas actuellement.

    Russia’s Arctic Agenda and the Role of Canada

    Publication: Eurasia Daily Monitor Volume: 17 Issue: 51 By: Sergey Sukhankin April 15, 2020 05:24 PM Age: 14 mins New research (which includes two articles written by Russian experts) published by the prominent think tank the Canadian Global Affairs Institute has spurred interest and hopes in Russia's expert community about the possibility of normalizing ties between Russia and Canada through cooperation in the Arctic region (Russiancouncil.ru, April 3; Cgai.ca, accessed April 12). This cooperation could potentially be premised on two main pillars. First would be the mutual rejection of “internationalization” of the Arctic. Both Canada and Russia—for whom the Arctic region is an issue of foreign policy (Russiancouncil.ru, July 1, 2019) —feel ill at ease with the increasing involvement of non-Arctic states in the region, particularly, China. Russian information outlets noted the level of distress when the Chinese icebreaker Snow Dragon completed its first-ever voyage through the Arctic Ocean off the coast of Canada, accumulating “a wealth of experience for Chinese ships going through the Northwest Passage in the future” (Regnum, September 17, 2017; see EDM, October 3, 2017). Second, Moscow seeks to exploit regional frictions and disagreements between Canada and the United States (Pentagonus.ru, accessed April 10) to boost its own position/influence in the region. Russian sources recall the year 2010, when then–Secretary of State Hillary Clinton publicly challenged Canada's stance on the status of the Northwest Passage, which Ottawa considers part of Canadian territory (Foreignpolicy.ru, February 20, 2015). In the past, both the Russian tone and general assessment of Canada's role in the Arctic were denigrating, claiming Ottawa lacked agency. Perhaps the clearest expression of this sentiment came from the director of the Institute of Strategic Planning and Forecasting, Professor Alexander Gusev, who, in 2015, declared that “they [Canada] are only performing the role assigned by the US” (Odnako.org, March 30, 2015). After 2016, however, Russia dramatically changed its coverage of the US-Canadian dispute in the Arctic region, with Moscow increasingly employing reconciliatory rhetoric toward Ottawa and employing ever more assertive public diplomacy tools. One notable example of this new approach is Moscow's reliance on pro-Russian experts based in Canada. In 2016, speaking in Sochi, on the margins of that year's Valdai Club session, Professor Piotr Dutkiewicz (a former director of the Institute of European and Russian Studies at Carleton University, in Ottawa) stated, “[T]his area [the Arctic region] will be the first one where we will feel real changes in our relations... Arctic cooperation will become the focal point thanks to which our two sides [Canada and Russia] will be extending their areas of collaboration” (Izvestia, October 28, 2016). Moreover, as repeatedly stated by Federation Council member Igor Chernyshenko (a senator from Murmansk Oblast), the Arctic region could become a “bridge,” helping Canada and Russia overcome the existing difficulties in their bilateral ties. Last May, he announced, “[W]e invited them [the Canadian side] to return to a dialogue. We proposed holding a conference between Russian and Canadian universities in northwest Russia, maybe in Murmansk Oblast. They supported this idea” (TASS, May 25, 2019). Notably, the last such event was held in November 2014, in Canada, hosted by the aforementioned Carleton University. In addition to trying to foster bilateral academic ties, Russia's outreach to Canada on Arctic issues involves sustained information campaigns via RT and similar multi-language information outlets with international reach. In particular, Russian propaganda narratives routinely overemphasize the extent of current US-Canadian disagreements in the Arctic. At the same time, foreign-audience-facing Kremlin-linked media outlets underscore the allegedly negative role of President Donald Trump (and his policies toward Canada) in aggravating the existing disputes. RT widely claimed that “after Trump's inauguration, he began pressing Ottawa on economic issues and extended claims on Canadian possessions in the Arctic region.” It also highlighted US Secretary of State Michael Pompeo's remarks suggesting that “Russia is not the only country with illegitimate claims [in the Arctic] ...the US has a lasting dispute with Canada over its claims on sovereignty over the Northwest Passage. Finally, RT's propaganda reporting also relied on a statement by Pavel Feldman, the deputy director of the Institute for Strategic Studies and Forecasts at the Moscow-based Peoples' Friendship University of Russia (RUDN). Feldman is quoted as saying, “[T]he US and Canada carry on a heated competition over the Arctic region; yet, publicly, these countries are trying to position themselves as partners” (RT, October 16, 2019). In recent months, this increasing Russian attention to Canada as an Arctic power and a key element of regional stability and order has started to be expressed at the highest levels in Moscow. Poignantly, President Vladimir Putin declared in a public address at the start of this year that Russia “is open to cooperation with Canada on the basis of mutual respect and consideration of each other's interest.” Putin added, “[O]ur countries are neighbors in the Arctic region and bear joint responsibility for the development of this vast region, for preservation of the traditional lifestyle of its native populations and the careful treatment of its brittle ecosystem” (Vzglyad, February 5, 2020). Such reconciliatory rhetoric should, however, be taken with a heavy dose of caution in Ottawa: from the earliest days of the Soviet Union, Moscow's stance on the Arctic region has been deliberately flexible and tightly premised on being able to demonstrate its military potential in the High North and to intimidate other regional players. The Russian Federation has increasingly undertaken the same policy course since 2014 (see EDM, April 9). Incidentally, on January 31, 2020, two Russian Tu-160 heavy strategic bombers approached Canadian airspace—maneuvers that the Russian Ministry of Defense explained away as “planned exercises” (Vpk.name, February 3). It is worth pointing out that the US North American Aerospace Defense Command (NORAD) is unable to identify and track Russian bombers of this type until they are close enough to launch missiles at targets on the continent. Furthermore, it is worth keeping in mind that, in fact, Russia (not the US) is Canada's direct competitor when it comes to territorial claims in the Arctic (the Lomonosov Ridge)—a point explicitly corroborated by Russia's Arktika 2007 expedition, which explored this disputed undersea area and famously planted a Russian flag at the North Pole, on the bottom of the Arctic Ocean (Izvestia, August 3, 2007). Lastly, it may be worth keeping an eye on one of the proposed amendments (soon to be officially adopted) to the Russian Constitution on the “prohibition of actions related to the alienation of Russian territory, or the propaganda thereof” (TASS, February 25). This amendment—reportedly drafted with predominantly Kaliningrad and Vladivostok in mind—is likely to also be applied to some Arctic territories that are of equally strategic interest to Canada. https://jamestown.org/program/russias-arctic-agenda-and-the-role-of-canada/

  • Germany looking to sell costly, rarely used drone to Canada

    Germany looking to sell costly, rarely used drone to Canada

    By: Frank Jordans, The Associated Press BERLIN — Germany is looking to sell a secondhand surveillance drone that has cost the country more than 700 million euros ($823 million) to Canada — without many core components it needs to fly. A defense ministry reply to lawmakers from the opposition Left Party states that Germany has decided to "begin concrete negotiations with Canada for the sale of the Euro Hawk aircraft, two ground stations and possibly certain spare parts." The government response, dated Sept. 19 and obtained by The Associated Press, adds that Germany isn't currently in talks with any other country or organization about the sale of the drone. In a statement Monday, Germany's defense ministry confirmed talks with Canada were planned, but declined to comment on a possible sales price or date. Officials at the Canadian Embassy in Berlin weren't immediately able to comment. Germany ordered the Northrop Grumman Global Hawk variant in 2000 to use for long-distance reconnaissance, but later canceled the order because of skyrocketing costs and revelations that the prototype wouldn't be certified to fly in Europe. Then-Defense Minister Thomas de Maiziere acknowledged in 2013 that the drone was a write-off, telling lawmakers it was better to have a "horrible end than a horror without end." Last year, the government acknowledged that the development and procurement of the prototype, a signals-intelligence sensor called "ISIS" and spare parts, and the completion of seven test flights had cost about 681 million euros since 2007. A further 24 million euros were spent on preparing for a resumption of temporary test flights. According to the government's latest response to Left Party lawmakers, which hasn't been published yet, the drone has already been "demilitarized." This entailed the removal of American-made radio equipment, the GPS receiver and aerials, as well as all encryption and the flight control system. Rather than laboriously delete individual software components, technicians chose to perform a "hardware uninstallation" — removing all hard drives containing sensitive U.S.-made software. "The question is what a buyer would do with such a gutted aircraft," said Thomas Wiegold, a German journalist who runs the defense website Augen Geradeaus . "Without GPS navigation and in particular without flight control systems, the drone would hardly be able to fly." Andrej Hunko, one of the Left Party lawmakers who submitted questions to the government, said the drone now only has "scrap value." "The sale will therefore recoup at best a small portion of the tax money spent," he said. "I expect the loss will amount to several hundred million euros (dollars)." Hunko, whose party objects to airborne military surveillance, said the drone's ground stations might still fetch a market price. https://www.defensenews.com/global/europe/2018/09/24/germany-looking-to-sell-costly-rarely-used-drone-to-canada
