Lockheed Martin s’apprête à vendre 105 F-35 au Japon

Les Etats-Unis ont annoncé le 9 juillet avoir approuvé la vente de 105 avions furtifs F-35 de Lockheed Martin au Japon, pour un montant estimé à 23,11 milliards de dollars, selon l'Agence de coopération pour la sécurité de la défense (DSCA). Dans le détail, il s'agit de 63 F-35A, la version traditionnelle de cet avion de combat destiné à l'armée de l'Air, et 42 F-35B, la version à décollage court et atterrissage vertical destinée aux porte-avions.

    Pentagon tests first land-based cruise missile in a post-INF treaty world (WATCH)

    By: Aaron Mehta WASHINGTON — The United States has tested a new ground-based cruise missile that is capable covering 500 kilometers in range, less than three weeks after officially exiting an arms treaty that banned such systems. The test occurred 2:30 PM Pacific time Sunday at San Nicolas Island, California, according to a Pentagon announcement. The missile “exited its ground mobile launcher and accurately impacted its target after more than 500 kilometers of flight,” the release said. “Data collected and lessons learned from this test will inform the Department of Defense's development of future intermediate-range capabilities.” The United States exited the Intermediate-Range Nuclear Forces (INF) treaty Aug. 2, following through on a decision made late last year that the treaty no longer benefited American interests. The INF was a 1987 pact with the former Soviet Union that banned ground-launched nuclear and conventional ballistic and cruise missiles with ranges of 500 to 5,000 kilometers. However, the United States and NATO allies have for years declared Russia in violation of the agreement. American officials have stressed they do not plan on building a nuclear ground-based cruise missile capability, but Secretary of Defense Mark Esper has said his department will “fully pursue the development of these ground-launched conventional missiles as a prudent response to Russia's actions and as part of the joint force's broader portfolio of conventional strike options.” Imagery of the test shows the weapon was launched from a Mark 41 Vertical Launch System, the same launcher used in the Aegis Ashore missile defense system. That is notable, as Russia has often claimed the Mk41 presence in Europe as a violation of the INF treaty, with the belief that the Aegis Ashore systems in Poland and Romania could be converted to offensive systems. “The launcher used in Sunday's test is a MK 41; however, the system tested is not the same as the Aegis Ashore Missile Defense System currently operating in Romania and under construction in Poland," Lt. Col Robert Carver, a Pentagon spokesman, said. “Aegis Ashore is purely defensive. It is not capable of firing a Tomahawk missile. Aegis Ashore is not configured to fire offensive weapons of any type.” The weapon itself is a variant of the Tomahawk Land Attack Cruise Missile, and was made by Raytheon, Carver said. During a recent trip to the Pacific, Esper also said he would like such weapon systems to end up in Asia as a deterrent to China. The governments in both Australia and South Korea quickly denied that any discussions about such a deployment had occurred, and Esper later downplayed his comments as a future objective. Congress will have a say in how such systems are developed or deployed. On Capitol Hill, a flashpoint in the fight is $96 million the administration requested to research and test ground-launched missiles that could travel within the agreement's prohibited range. The Democrat-controlled House passed a spending bill that would deny the funding ― and a defense authorization bill that would deny it until the administration shares an explanation of whether existing sea- and air-launched missiles could suffice. Senate Republicans are expected to fight that language during the reconciliation process. https://www.defensenews.com/pentagon/2019/08/19/pentagon-tests-first-land-based-cruise-missile-in-a-post-inf-treaty-world/

    Marine Hovercraft From Textron Flawed by Propeller Cracks

    By Anthony Capaccio The U.S. Navy accepted delivery this year from Textron Inc. of the first two in a new generation of hovercraft for the Marines despite “extensive propeller blade cracking” that will require a redesign, according to service officials and documents. The previously undisclosed problem was discovered during mid-2019 tests of the $5.7 billion program to build new air-cushion hovercraft to move Marines from ship to shore. Even with the cracks unresolved, the Navy awarded Textron a $386 million contract for 15 more hovercraft that Congress had approved for fiscal years 2017-2020. But ordering those vessels was held up pending resolution of other technical problems, including issues with the main gearbox, drive-train integration and lubrication system, navigation electronics and bearings. The first two deliveries, in February and August, were each three years late. Hovercraft “have always been important for supporting the Marine Corps' ability to land forces ashore, and in coming years they are to form part of the toolkit for implementing the Corps' new wartime island-hopping strategy for countering Chinese military forces in the Western Pacific,” Ronald O'Rourke, an analyst with the Congressional Research Service, said. Taking delivery of the first two hovercraft allowed the Navy to begin initial operator training and “to move into the post-delivery test and trials period as we identify long-term” solutions for vessels in production, Navy spokeswoman Colleen O'Rourke said in an email. She described the flaws as “micro-cracks” in the composite structure of the blades that don't pose a safety hazard or “an immediate impediment” to operations. “The program is the first major naval acquisition program in more than 15 years to be designed ‘in-house' by the Navy rather than by private industry,” according to a Navy fact sheet. Reinforced Blades O'Rourke said the Navy, Providence, Rhode Island-based Textron and subcontractor Dowty Propellers, a division of General Electric Co., conducted a study “to understand the underlying cause and mechanisms to improve propeller blade performance.” That led to a near-term plan to provide “reinforced blade sets that will deliver later this year” while production and post-delivery testing continue and “blade redesign efforts are underway,” she said. She added that the eventual solution for the 73 hovercraft, known as Ship to Shore Connectors, “is not anticipated to result in any significant program cost increases.” Scott Donnelly, Textron's chief executive officer, told analysts Thursday on an earnings call that the program is “steadily improving” and “we're starting to feel good about that.” He said the contractor has “started to get more craft deliveries, the production lines are starting to run better, we're starting to get supply parts coming in at the right time” so “that's a program that obviously is going to start to be a contributor to the profit in the rest of the businesses.” Textron rose 6.6% to $34.21 at 10:24 a.m, the most since July 30, after third-quarter earnings per share from continuing operations beat the average analyst estimate. Currently, 12 additional hovercraft are under construction in Slidell, Louisiana. The vessels will replace the aging Landing Craft Air Cushion vehicle that became operational in 1986. The Ship-to-Shore Connector is a “franchise program” for Textron's Marine & Land Systems division, “which could more than double in revenue over the coming years as production accelerates,” Bloomberg Intelligence analyst Douglas Rothacker said in an email. Textron reports third-quarter earnings Thursday. Procurement funding is projected to soar from $20 million the Navy requested for this fiscal year to almost $380 million by 2025, according to program documents. The Navy's fiscal 2021 Selected Acquisition Report, obtained by Bloomberg News, said initial “Builders Trial” testing in mid-2019 uncovered “technical concerns with the propeller blades.” This resulted in a decision to divide the subsequent formal acceptance test into two events -- “unloaded” and “loaded,” which simulated carrying a 74-ton M1 tank. “After the loaded builders test, craft inspection revealed extensive propeller blade cracking,” it said. “To avoid additional blade loss,” the first vessel's acceptance tests “were conducted unloaded.” https://www.bloomberg.com/news/articles/2020-10-29/marines-combat-hovercraft-from-textron-have-cracked-propellers
