Le Japon va acquérir 105 avions de combat américains F-35

Le Japon va acheter 105 avions de combat américains F-35 supplémentaires, a annoncé lundi le président américain Donald Trump à l'issue d'un sommet avec le premier ministre japonais Shinzo Abe.

« Les États-Unis soutiennent les efforts du Japon pour améliorer ses capacités de défense, et ces derniers mois nous leur avons envoyé une grande quantité d'équipements militaires », a déclaré M. Trump lors d'une conférence de presse, annonçant « l'intention du Japon d'acheter 105 F-35 neufs ».

Le Japon, qui avait déjà annoncé fin 2011 l'achat de 42 F-35, est avec cette nouvelle commande le premier client international pour cet avion de combat de cinquième génération.

En réalité, l'archipel s'était déjà engagé en décembre à cette acquisition, portant à 147 le nombre de ces chasseurs furtifs en sa possession, selon un communiqué du constructeur aéronautique américain Lockheed Martin publié à l'époque.

Le gouvernement de Shinzo Abe, qui a annoncé en décembre un budget record pour la défense, a accru ses importations d'équipements militaires américains sous la pression de Donald Trump. Le but est de contrer la menace militaire de la Chine, mais aussi de réduire le déséquilibre commercial avec les États-Unis, régulièrement dénoncé par le président américain.

Lancé au début des années 1990, le F-35 est produit par Lockheed Martin, et ses moteurs par un autre américain, Pratt et Whitney.

Selon les derniers chiffres, 390 F-35 ont été livrés dans le monde. C'est le plus cher des programmes d'armement de l'histoire militaire américaine, avec un coût estimé au total à près de 400 milliards de dollars pour l'armée américaine, pour un objectif de près de 2500 appareils à produire dans les décennies à venir.

    How tensions with Iran could test a new cyber strategy

    Mark Pomerleau In 2018, the Department of Defense began following a new philosophy for cyber operations to better protect U.S. networks and infrastructure. Known as “defend forward,” the approach allows U.S. cyber forces to be active in foreign network outside the United States to either act against adversaries or warn allies of impending cyber activity that they've observed on foreign networks. After the U.S. military killed an Iranian general in a Jan. 2 drone strike and after national security experts said they expect Iran might take some retaliatory action through cyber operations, the specter of increased cyber attacks against U.S. networks puts Cyber Command and its new approach front and center. “This Iran situation today is a big test of the ‘defend forward' approach of this administration,” James Miller, senior fellow at Johns Hopkins Applied Physics Laboratory and former undersecretary of defense for policy, said at a Jan. 7 event hosted by the Council on Foreign Relations. “Will [Cyber Command] take preventative action? Will they do it in a way that our allies and partners support and that can be explained to the public?” While Iran fired several missiles Jan. 7 at a base in Iraq where U.S. troops lived as an initial response to the drone strike, many national security experts expect Iran could continue cyber actions as further retaliation for the strike. Iran could also ratchet up its cyber operations in the United States following the collapse of portions of the 2015 nuclear deal between the United States, Iran and five other nations to curb Iran's nuclear weapons capability in return for sanctions relief. Over the past 12 months, the White House and Congress streamlined many of the authorities used to conduct cyber operations to help cyber forces to get ahead of threats in networks around the world. One such provision in last year's annual defense policy bill provides the Pentagon with the authority to act in foreign networks if Iran, among other named nations, is conducting active, systematic and ongoing campaigns of attacks against the U.S. government or people. Cyber Command declined to comment on what, if anything, they were doing differently since the drone strike. Some experts, however, have expressed caution when assessing how well this defend forward approach has worked thus far given it is still relatively new. “The jury is very much still out here,” Ben Buchanan, assistant professor and senor faculty fellow at Georgetown University, said at the same event. “We don't have a lot of data, there's been a lot of hand-wringing ... about these authorities and about how Cyber Command may or may not be using them. I just don't think we've seen enough to judge whether or not ... [it is] meaningfully changing adversary behavior.” Others have also expressed reservations about how effective Iran can even be in cyberspace toward U.S. networks. “Iran is a capable cyber actor, Iran is a wiling cyber actor. That means Iran will conduct cyberattacks,” said Jacquelyn Schneider, Hoover fellow at the Hoover Institution at Stanford University. “It's not like they have this capability and they've been deterred in the past and maybe now they're going to turn it on. I think they've been trying this entire time.” Complicating matters further could be other actors trying to take advantage of U.S.-Iran imbroglio for their own interests. Priscilla Moriuchi, senior principal researcher and head of nation-state research at threat intelligence firm Recorded Future, said over the past several months, there have been reports of Russian state-affiliated actors hijacking Iranian cyber infrastructure to conduct operations masquerading as Iranians. “That creates its own uncertainty,” she said at the same event. “Another level of potential what we call inadvertent escalation if a country perceives that they are attacked by Iran but in reality, it” wasn't. https://www.fifthdomain.com/dod/2020/01/09/how-tensions-with-iran-could-test-a-new-cyber-strategy/

    JUST IN: Defense Department to Stand Up New Counter-Drone Office

    By Yasmin Tadjdeh The Pentagon will soon stand up a counter-unmanned aerial system office that will be headed by the Army, said the Defense Department's top weapons buyer Jan. 14. Following the Dubai Air Show in November, Undersecretary of Defense for Acquisition and Sustainment Ellen Lord visited numerous locations across the Middle East including U.S. military installations in Iraq and Afghanistan. “The thing that was really top of everybody's mind were counter-UAS,” she said during a meeting with reporters hosted by George Washington University's Project for Media and National Security in Washington, D.C. “We see that small UAS are becoming a more popular weapon of choice ... [and] we need to be agile and pivot to that challenge.” Pentagon leaders recently decided to designate the Army as the executive agent for counter-drone technologies, Lord said. The new office will be stood up in Arlington, Virginia, in the Crystal City neighborhood. It will be staffed by around 60 people. “We are just finishing off on the policy that directs the activities,” she said. The office will examine the many counter-UAS efforts across the Defense Department and come up with three to five systems that are best for the military writ large and make sure they are effectively leveraged, Lord said. The Defense Department is bringing together a number of organizations, including the office of the director of operational test and evaluation and Defense Digital Service, to work on the effort. Robert Behler, the head of DOT&E, has a group conducting independent tests and evaluation of currently fielded systems, Lord noted. “Come April we will have that evaluation completed and written up. And that coincides [with] when we want to make some decisions about downselecting ... to the three to five systems that would be utilized,” she said. The department is examining a variety of sensor modalities and defeat mechanisms. “One size does not fit all,” Lord said. “You need a system with multiple sensors ... or defeat systems. And the key is really the command-and-control and then the communication across theater.” The office aims to thwart both small and large adversary UAS, she added. Countering rogue and enemy drones has long been an objective for the Defense Department, but recent high-profile events have thrown the technology into the spotlight. That includes an alleged Iranian attack on Saudi Aramaco facilities in September using unmanned aircraft. “One of the challenges is that we know that the adversary is very agile and updates their [tactics, techniques and procedures] ... very quickly,” Lord said. “We are looking at a very nimble system where we can push patches in the same day, if you will, so that we again can stay ahead of" the threat. The Pentagon is gung-go about tackling the issue, and senior leadership involvement and funding are increasing, she noted. In terms of the industrial base, counter-UAS is one of the acquisition and sustainment office's four key focus areas, Lord said. Others include microelectronics, 5G networks and hypersonics. The department plans to establish a hypersonics "war room." “We just decided last week that we would stand up a hypersonics war room to begin to look at the defense industrial base and begin to have different companies [come] in,” Lord said. The technology is the Pentagon's top research-and-development priority and it plans to buy large numbers of systems when they are mature enough to be fielded. Last week, Secretary of the Army Ryan McCarthy said missile manufacturers and other suppliers need to do more to boost their hypersonics manufacturing capability. “What we need to see is industry step up,” he said Jan. 10 during remarks at the Brookings Institution. “They've got to come forward and ... first and foremost, invest the time to work with our national lab network to understand how we've come forward with these technologies. But they're going to have to make investments to be able to produce these at scale.” https://www.nationaldefensemagazine.org/articles/2020/1/14/just-in-defense-department-to-stand-up-counter-drone-office
