Essor des missiles hypersoniques : l’impact stratégique

Le Figaro, qui rappelle que la Corée du Nord a annoncé avoir testé avec succès pour la première fois un planeur « hypersonique », le 28 septembre, revient sur l'impact stratégique de l'essor des armes hypersoniques. L'« hypervélocité », c'est-à-dire la capacité de voler à plus de six fois la vitesse du son, pourrait « bouleverser les équilibres militaires », souligne le quotidien. La Russie a procédé début octobre à deux tirs d'essai de son missile de croisière hypersonique Zircon depuis un sous-marin en immersion. De leur côté, les États-Unis mènent plusieurs projets baptisés C-HGB, ARRW et HAWC. Le 27 septembre, la Darpa, l'agence de recherche de l'armée américaine, annonçait avoir réussi un vol test de son système HAWC. La Chine dispose elle aussi d'un missile de croisière supersonique, le DF-100, et d'un planeur hypersonique, le DF-17, et entend achever l'année prochaine la construction de la soufflerie JF-22, capable de simuler des vols à Mach 30. En France, un vol de démonstration du planeur hypersonique V-MAX, développé par ArianeGroup, est annoncé prochainement.

    GM Defense conducting nationwide search for new president

    By: Jen Judson WASHINGTON — GM Defense President David Albritton is headed to Amazon so the company is conducting a nationwide search for a new president, according to a GM spokesperson. Albritton is joining Amazon Web Services as the vice president of global communications in the company's public sector and vertical industries. GM Defense's website already reflects the change. Tim Herrick, the company's vice president of global product programs, is serving as the interim president and will be dual-hatted until a permanent replacement is found. Herrick “has been a champion of GM's defense business since its inception and serves on GM Defense's Board of Managers,” a GM Defense spokesperson told Defense News in an emailed statement Nov. 19. GM Defense is conducting a “national search to find a candidate who is qualified to lead GM Defense and will make an announcement when the right person is identified,” according to the spokesperson. The company is coming off a big win with the U.S. Army after being selected to build its new Infantry Squad Vehicle. The first of the vehicles was delivered to the service in a ceremony last month at GM Defense's proving grounds and production facility in Milford, Michigan, just 120 days after being chosen to build the new troop carrier. The Army awarded the company a $214.3 million contract to produce 649 vehicles by the end of fiscal 2024. The service is planning to procure a total of 2,065 ISVs. With the success of the ISV program, GM Defense is setting its sights on other opportunities with the Army and other military services such as the Joint Light Tactical Vehicle program. The service is planning to re-compete for the JLTV and for new Humvees to round out the tactical vehicle fleet. And while the company can offer fully integrated vehicles, it is also looking to partner with others for such programs like the Advanced Reconnaissance Vehicle for the U.S. Marine Corps or the Optionally Manned Fighting Vehicle, the Army's Bradley Infantry Fighting Vehicle replacement effort. Such technologies like power and propulsion, lighter weight materials and cybersecurity are all areas in which GM Defense is looking to contribute. GM spent several recent years helping the Army evaluate a hydrogen fuel cell vehicle using a ZH2 Chevy Colorado and the Army is now taking some renewed steps at getting after an electric vehicles in its fleet to include the pursuit of an electric light reconnaissance vehicle. https://www.defensenews.com/land/2020/11/19/gm-defense-conducting-nationwide-search-for-new-president
