Les Royal Marines testent une combinaison volante (« jet pack »)

Les forces navales anglaises ont testé l'utilisation d'une combinaison volante, ou « jet pack », pour une manœuvre d'embarquement sur un bateau patrouilleur. La startup britannique Gravity Industries a développé un système de propulsion composé de cinq mini-réacteurs alimentés en kérosène : deux à chaque bras et un dans le dos. Le système a été testé en pleine mer début mai. « Bien qu'il soit sans aucun doute impressionnant, les experts ont conclu que le kit n'est pas encore prêt pour une utilisation militaire », a précisé la Royal Navy, qui souhaite observer avec un « intérêt constant » les futurs développements de la combinaison volante.

  • Lockheed and Bell will compete head-to-head to build US Army’s future attack recon aircraft

    Lockheed and Bell will compete head-to-head to build US Army’s future attack recon aircraft

    By: Jen Judson WASHINGTON — Sikorsky, a Lockheed Martin-owned company, and Bell have been selected to build and fly Future Attack Reconnaissance Aircraft (FARA) prototypes for the U.S. Army in a head-to-head competition, according to a March 25 Army statement. The Army is planning to procure both a FARA and Future Long-Range Assault Aircraft (FLRAA) that will slowly replace the current fleet of Sikorsky-manufactured UH-60 Black Hawks utility helicopters and Boeing-made AH-64 Apache attack helicopters. The service plans to initially field both in the 2030s. FARA will fill a critical capability gap currently being filled by AH-64E Apache attack helicopters teamed with Shadow unmanned aircraft following the retirement of the OH-58D Kiowa Warrior helicopters. The service has tried and failed three times to fill the gap with an aircraft. The Army had selected five teams to provide FARA designs last spring: AVX Aircraft Co. partnered with L-3 Communications Integrated Systems, Bell, Boeing, Karem Aircraft and Sikorsky. The Army laid out a handful of mandatory requirements that the vendors had to meet and also a list of desired requirements for initial designs, Col. Craig Alia, the Future Vertical Lift Cross Functional Team chief of staff, told reporters last year. The service also looked at the vendors' execution plans and evaluated timing as well as funding profile requirements. “The ones that were selected were clearly meeting the mandatory requirements and were in the acceptable risk level of the execution plan and the desired requirements," Dan Bailey, who is the FARA competitive prototype program manager, added. The prototype program falls under the purview of the Army Combat Capabilities Development Command Aviation and Missile Center's Aviation Development Directorate. Lockheed unveiled its design — Raider X — at the Association of the U.S. Army's annual conference in October 2019. The company's design uses its Raider X2 coaxial technology with a focus on how it will perform “at the X.” “One thing that always comes out is the importance of this aircraft at the X,” Tim Malia, Sikorsky's director of future vertical lift light, told Defense News in an interview last fall. “The ‘X' is defined by the Army as the terminal area where they actually have to go do the work, do the reconnaissance, do the attack mission. The operation at the X is really critical for this program and for this platform.” That's where Raider X comes in. It's a slightly larger version of the Raider coaxial helicopter that Lockheed has been flying for several years at its West Palm Beach, Florida, flight test center. “Through our mature S-97 RAIDER technology demonstrator, we continue to optimize our FARA solution, which will provide the Army with an integrated weapon system that combines speed, range, maneuverability, survivability and operational flexibility," Andy Adams, Sikorsky's vice president of future vertical lift, said in a March 25 statement. This approach is driving down risk and will result in an aircraft solution that is capable of executing the Army's joint all-domain operations." Bell revealed its design — the Bell 360 Invictus — which is based on 525 technology. But its design features several key differences, including its size in order to adhere to the Army requirement of 40-foot in diameter rotor blades. The design includes a single main rotor helicopter in a four-blade configuration, a low-drag tandem cockpit fuselage and transportability in a C-17. “Bell is proud to continue work on the Bell 360 Invictus as part of the Army's Future Attack Reconnaissance Aircraft Competitive Prototype competition,” Keith Flail, Bell's vice president of advanced vertical lift systems, told Defense News on March 25. “We have made significant investment and begun manufacturing in order to preserve the Army's schedule for FARA CP and we are thrilled to continue our work on the Invictus,” he said. “Bell's approach from the beginning has been tailored to deliver the advanced performance required without excessive complexity in order to get critical capability in the hands of the warfighter quickly and affordably.” The AVX and L3 team was the earliest to unveil its design for the FARA competition at the Army Aviation Association of America's annual summit in Nashville, Tennessee, in April 2019. The design uses AVX's compound coaxial and ducted fans technology. The companies said its single-engine design meets 100 percent of the Army's mandatory requirements and 70 percent of its desired attributes. Karem announced it would team with Northrop and Raytheon and came out with its design at AUSA — its AR-40 — with a single main rotor, tilting compound wings and a rotating tail rotor. Boeing was the last to reveal its design, coming out with it March 3. The company's clean-sheet design featured a hingeless, six-bladed, high-solidity main rotor; a four-bladed conventional tail rotor; and a propeller on the back. The prototype aircraft are expected to start flying in the fourth quarter of fiscal 2022, and the flight test is expected to run through 2023. The engineering and manufacturing development phase is expect to begin in FY24. https://www.defensenews.com/smr/army-modernization/2020/03/25/lockheed-and-bell-will-compete-head-to-head-to-build-us-armys-future-attack-recon-aircraft

  • How Poland plans to land an F-35 deal and ‘Fort Trump’

    How Poland plans to land an F-35 deal and ‘Fort Trump’

    By: Jaroslaw Adamowski This story has been updated to provide details about President Trump's decision to stay in the United States rather than make a planned visit to Poland in order to deal with a hurricane at home. WARSAW, Poland — By 2026, the Polish Ministry of Defence plans to allocate about 185 billion zloty (U.S. $47 billion) toward acquiring new weapons and military equipment, with fifth-generation fighter jets a top priority. Twenty years after Poland joined NATO, and despite the integration of some Western-made fighter jets and armored vehicles, the country still uses Soviet-designed gear dating back to the 1955 Warsaw Pact. Poland and other allies in Eastern Europe are intensifying their military modernization efforts in response to Russian activity along NATO's eastern flank and its annexation of the Crimean Peninsula from Ukraine. For 2019, the Polish MoD set a record budget, at more than 44 billion zloty, as required by the country's plan to raise defense spending to 2.1 percent of gross domestic product in 2020, and reach 2.5 percent in 2030. A significant share of the country's defense spending is to be directed at the acquisition of Western-made gear. Warsaw's potential acquisition of fifth-gen fighters is one of the top modernization projects in the pipeline. In May, Polish Defense Minister Mariusz Blaszczak said the ministry sent a letter of request to the U.S. regarding Warsaw's plan to acquire 32 F-35A aircraft. The fighters are to replace the Air Force's outdated, Soviet-designed Sukhoi Su-22 and Mikoyan MiG-29 jets. Negotiations for the jets are taking place as Warsaw is seeking a permanent U.S. military presence in Poland, dubbed “Fort Trump.” Warsaw offered to allocate at least $2 billion toward the project under which the U.S. would build a military base in the country. On June 12, Polish President Andrzej Duda met with U.S. President Donald Trump in Washington to discuss the initiative and ink a joint declaration on defense cooperation regarding U.S. force posture in Poland. “The United States plans to enhance its current military presence of approximately 4,500 rotational U.S. military personnel in Poland. This enduring presence is expected to grow by about 1,000 additional U.S. military personnel in the near-term, and would focus on providing additional defense and deterrence capabilities in Poland,” the declaration read. “With the understanding that the increased U.S. force presence in Poland is made sustainable with Polish support, Poland plans to provide and sustain jointly determined infrastructure for the initial package of additional projects listed below, at no cost to the United States and taking into account the planned level of its use by U.S. forces.” Trump was scheduled to visit Poland, but he canceled the trip to deal with a hurricane at home. The topics of a stronger U.S. troop presence in the country, as well as a potential F-35 sale, were expected to come up. Trump is instead sending Vice President Mike Pence to observances Sunday marking the 80th anniversary of the start of World War II and for meetings with Polish leaders Monday expected to include new military and energy deals. But F-35 acquisition negotiations will likely be separate from Fort Trump discussions, as the logistics and technical aspects of a troop deployment deal are nearing a conclusion, according to Tomasz Smura, the director of the research office at the Warsaw-based Casimir Pulaski Foundation. “If Poland decides to buy the F-35, this will open an array of new possibilities before the Polish Air Force in the upcoming decades. This aircraft offers stealth and interoperability capacities that are currently not available to the Polish military,” Smura told Defense News. “However, there are also some critical voices on this potential purchase. Some analysts doubt whether we should introduce a second type of fighter instead of expanding Poland's fleet of 48 F-16s. This number of modern fighter jets doesn't match Poland's military needs and the country's size. Other analysts add that we're simply not ready to fully use the capacities offered by the F-35, and that further F-16s would suffice to match the current state of development of the air forces of our eastern neighbors.” Despite the country's rising defense expenditure, some observers also doubt Poland's capacity to finance the F-35 acquisition alongside other ambitious military procurements, such as the Wisla air defense program. In March 2018, Poland signed a letter of offer and acceptance with the U.S. government to purchase Raytheon's medium-range Patriot system. Under the deal, Warsaw is to acquire two Patriot Configuration 3+ batteries fitted with Northrop Grumman's Integrated Air and Missile Defense Battle Command System, as well as Lockheed Martin-made Patriot Advanced Capability-3 Missile Segment Enhancement missiles. Deliveries are expected by the end of 2022, with plans to reach an initial operational capacity around the 2023-2024 time frame, according to data from the Polish MoD. Warsaw's other procurement plans include short-range air defense systems, combat helicopters for the country's Air Force, new submarines for the Polish Navy, UAVs for various military branches, and the buildup of cyber warfare capacities using new hardware, the ministry said. https://www.defensenews.com/digital-show-dailies/dsei/2019/08/29/how-poland-plans-to-land-an-f-35-deal-and-fort-trump/
