Boeing: Apache helicopter fix could take until past 2020 to complete

By:

WASHINGTON — Boeing has made progress on installing a “safety critical” part across the AH-64 Apache fleet, but it will probably take until at least 2020 for the company to finish the retrofit process, Boeing program officials said Tuesday.

In April, Defense News revealed that the U.S. Army had suspended AH-64E Apache attack helicopter deliveries due to corrosion the service noticed on the aircraft's strap pack nut, which hold the heavy bolts that attach the rotor blades to the helicopter. The service resumed accepting deliveries on August 31 after Boeing designed a new strap pack nut that will be outfitted on AH-64Es coming off the line.

The company has now retrofitted new strap pack nuts on about 25 percent of the Army's AH-64D/Es, Kathleen “KJ” Jolivette, director of U.S. Army Services for Boeing Global Services, said during an Oct. 9 roundtable with journalists at the Association for the U.S. Army annual conference.

However, Steve Wade, vice president Boeing attack helicopters, said the fastest the company could move to finish retrofitting the Apache fleet is 2020, saying that “the limiting factor is how fast we can build” retrofit kits.

Boeing's best case completion date appears to be at least a full year behind the Army's own projections. In September, Brig. Gen. Thomas Todd, the service's program executive officer for aviation, said that he expected retrofits of the U.S. Army's Apache fleet to occur by 2019, with the strap pack nut replacements paid for by the company.

    Armement : les coopérations européennes se multiplient

    ANNE BAUER Pour le patron de la DGA Joël Barre, l'un des principaux défis de 2019 est de donner corps aux multiples programmes en partenariat avec d'autres pays européens. Le dialogue avec l'Allemagne est compliqué. Les restrictions budgétaires présentées mercredi par la loi de finances rectificative 2018 n'auront pas de conséquences significatives sur les livraisons d'équipements aux armées, a promis jeudi le directeur général de l'armement (DGA) Joël Barre. Son administration, chargée de l'équipement des forces, avait anticipé ce gel par une gestion prudente, a-t-il expliqué, en soulignant que les 319 millions d'euros d'annulations de crédits annoncés mercredi ne représentent que 3 % du budget d'équipement de 2018. 12,7 milliards de commandes Cette année, la DGA peut engager 12,7 milliards d'euros contre 11,2 milliards l'an dernier, tandis que le montant prévu en 2019, première année d'application de la nouvelle loi de programmation militaire, atteindra 14,3 milliards d'euros. Parmi les investissements importants, la marine commandera en 2018 et 2019 ses cinquième et sixième sous-marins Barracuda, 4 navires pétroliers ravitailleurs et plusieurs patrouilleurs. L'armée de l'air bénéficiera de la rénovation des avions Rafale au nouveau standard 3, avec notamment le nouveau missile air-air, MICA NG, dont 567 exemplaires seront commandés. Quant à l'armée de terre, elle recevra enfin ses premiers « Griffon », les blindés légers de nouvelle génération. Une année sans panache pour les exportations A l'exportation, l'industrie française de défense enregistre « une année normale », résume Joël Barre, en déclarant s'attendre en 2018 à quelque 7 milliards d'euros d'exportations, comme en 2017 - après 16 milliards en 2016 et 14 milliards en 2015, années de la vente de 12 sous-marins en Australie et de 96 Rafale à l'Egypte, le Qatar et l'Inde. Joël Barre a d'ailleurs confirmé que les négociations avec l'Australie se poursuivaient pour définir l'accord de partenariat stratégique et débloquer une nouvelle tranche de contrats de 1,5 milliard d'euros. Il a par ailleurs confirmé que la DGA avait estimé que « les conditions n'étaient pas réunies » pour que Dassault Aviation participe au futur appel d'offres que souhaite lancer le Canada en 2019 pour acquérir 88 avions de combat. Notamment parce que la France n'appartient pas à l'alliance dite des « Five Eyes » formée par les services de renseignement du monde anglo-saxon (Royaume-Uni, Australie, Canada et Nouvelle-Zélande). Ce qui aurait compliqué l'échange de renseignements avec les Américains. Multiples coopérations européennes Pour la DGA, les principaux défis de 2019 sont toutefois de donner vie à la coopération européenne. Avec le Royaume-Uni, la DGA cherche comment maintenir un courant d'échanges dans l'aviation de chasse « pour garder le contact », tandis que se poursuit le programme commun sur un nouveau missile, capable de remplacer les actuels missiles anti-navires Harpoon et Exocet, ainsi que les missiles de croisière Scalp et Storm Shadow. Deux nouveaux partenariats viennent d'être conclus, avec l'Italie via l'alliance entre Naval Group et Fincantieri, et avec la Belgique, qui vient de signer un accord intergouvernemental avec la France pour s'équiper comme l'armée de terre française en blindés. Reste le partenariat le plus ambitieux mais le plus compliqué à mettre en place : celui pour concevoir avec l'Allemagne le char du futur et le système de combat aérien du futur (Scaf). « Notre espoir est de pouvoir lancer les premières études sur le Scaf en janvier 2019 », a précisé Joël Barre, sans cacher que cet enjeu essentiel en développements technologiques et industriels faisait l'objet de discussions musclées. Alors que l'industrie aéronautique française est en avance sur l'allemande, les industriels français s'inquiètent des ambitions de leurs voisins.

    International Hypersonic Strike Weapons Projects Accelerate

    James Bosbotinis June 15, 2020 There is growing international interest in the development of offensive hypersonic weapon systems, particularly following the deployment by Russia and China of nascent hypersonic strike capabilities. France, India, Japan and the UK all are seeking to develop a hypersonic strike capability too. Beyond Russia's Avangard hypersonic glide vehicle (HGV) and Kinzhal air-launched ballistic missile (ALBM), and China's DF-17 HGV, both nations are developing additional hypersonic weapon systems. Russia, for example, is working on the Zircon hypersonic cruise missile (HCM) and related technologies, while China is developing an expansive technological base and infrastructure for the development and production of hypersonic systems for military, commercial and space applications. Given the technical challenges and cost inherent in developing hypersonic weapons, particularly in areas such as propulsion, airframe design, guidance and thermal management, what roles will such weapons undertake? The speed, maneuverability and flight characteristics of hypersonic weapons makes them challenging to detect, track and intercept, reducing the warning time available and window for interception. Hypersonic weapons thus provide advantages for the prosecution of time-critical targets, mobile or relocatable targets or in the face of adversary missile defense capabilities. Maritime strike is also a key projected role for hypersonic missiles under development or being deployed by Russia, China and Japan. In the conventional precision-strike role, hypersonic weapons will require a robust set of supporting intelligence, surveillance, target acquisition and reconnaissance capabilities, in particular for the prosecution of mobile/relocatable targets. France is developing its fourth-generation air-launched nuclear missile, the ASN4G, which will be scramjet-powered and is due to enter service in the mid-2030s, replacing the current ASMP-A. It is also developing an HGV demonstrator, the “Vehicule Manoeuvrant Experimental,” or V-MaX, which is due to make its first flight before the end of 2021. India is similarly pursuing two hypersonic weapon projects, the BrahMos-2, developed by the BrahMos joint venture between India and Russia, and another HCM project. The BrahMos-2 is intended to be an HCM capable of speeds of Mach 5-7; HCM development is supported by the scramjet-powered Hypersonic Technology Demonstrator Vehicle (HSTDV). An attempted test flight in June 2019 failed due to a technical problem with the Agni-1, serving as the launch platform for the HSTDV. Japan has outlined plans for two hypersonic weapon systems; the Hyper-Velocity Gliding Projectile (HVGP) and a Hypersonic Cruising Missile. Japan outlined in its Midterm Defense Program (fiscal 2019-23) plans to strengthen the defense of “remote islands in the southwest region,” including through the establishment of HVGP units. The HVGP is intended to be a tactical HGV, capable of delivering a penetrating warhead for targeting, for example, aircraft carriers, or a “high-density EFP” (explosively formed penetrator) warhead for “area suppression.” An initial variant will be deployed in the 2024-28 time frame with an improved variant following in the 2030s. The Japanese HCM will be a scramjet-powered missile, armed with the same warheads as the HVGP, and intended to provide a standoff capability to counter “ships and landing forces attempting to invade Japan.” The HCM will be deployed in the late 2020s/early 2030s, with an improved variant following later in the 2030s. The UK is exploring options for the development of a hypersonic strike capability, including potentially as part of the joint Future Cruise/Anti-Ship Weapon project with France to replace the Storm Shadow/SCALP standoff cruise missile and the anti-ship Exocet and Harpoon from 2030. In July 2019, Air Vice Marshal Simon Rochelle, then chief of staff capability, announced that the UK sought to deploy an affordable, air-launched hypersonic weapon by 2023. Moreover, as Aviation Week disclosed, a joint U.S.-UK study, Thresher (Tactical High-Speed, Responsive and Highly Efficient Round), is underway between the U.S. Air Force Research Laboratory and UK Defence Science and Technology Laboratory (AW&ST April 6-19, p. 14). It is due to be completed in 2022 or 2023. With the notable exception of the UK's intention to rapidly acquire a hypersonic missile by 2023, the majority of known programs are not likely to deliver weapon systems until the second half of the 2020s or 2030s. This period is also likely to see a significant expansion in Russian and Chinese hypersonic strike capabilities. Russia possesses a nascent hypersonic strike capability following the initial deployment in December 2017 of the Kinzhal ALBM and in December 2019 of the Avangard HGV system. The Kinzhal and Avangard were both announced by President Vladimir Putin in his state of the nation address on March 1, 2018, and reflect Russia's long-term efforts to develop hypersonic weapons, particularly as a response to U.S. missile defense efforts. Although seeming to catch the U.S. public by surprise, the development of the Avangard can be traced back to the Albatross project started in the late 1980s as part of the Soviet response to the U.S. Strategic Defense Initiative. NPO Mashinostroyeniya performed several tests of the Yu-70 prototype in 1990-92, until the program was put on hiatus amid the dissolution of the Soviet Union, says Markus Schiller, founder of ST Analytics and a Germany-based consultant on hypersonic technology. The Yu-70 project was revived shortly after Putin assumed power in 2000, leading to a series of test flights in 2001-11. The Avangard HGV is based on an improved version known as the Yu-71, which performed a series of tests in 2013-18, Schiller says. The development of hypersonic weapons also reflects Russia's interest in developing a robust conventional long-range precision-strike capability as part of its wider military modernization efforts. It is developing and deploying both nuclear and conventionally armed hypersonic weapons, including dual-capable systems, to undertake tactical and strategic roles. In addition to the Avangard and Kinzhal, at least three more development programs are underway: the Zircon, GZUR (deriving from the Russian for “hypersonic guided missile”) and an air-launched weapon to arm the Sukhoi Su-57 Felon. The Avangard is an ICBM-launched HGV, initially equipping the UR-100N, a modernized version of the SS-19, and might equip the developmental SS-X-29 Sarmat (Satan 2). The Avangard is reportedly capable of attaining speeds in excess of Mach 20, can maneuver laterally and in altitude, and can travel intercontinental distances. Although principally intended as a nuclear system, the Avangard can reportedly also be used in the conventional strike role. The Kinzhal is a dual-capable, air-launched derivative of the Iskander-M tactical ballistic missile, with a range of 2,000 km (1,250 mi.) and a speed of Mach 10. It is being deployed with a modified variant of the Mikoyan MiG-31, the MiG-31K, and may be integrated with other aircraft, including reportedly the Tupolev Tu-22M3 Backfire. Russia is also developing a scramjet-powered HCM, the 3K22 Zircon, which will be capable of speeds up to Mach 9, have a range in excess of 1,000 km, and operate in the land attack and anti-ship roles. The Zircon will be compatible with existing launchers capable of launching the Oniks supersonic cruise missile, such as the UKSK vertical launch system. It is due to enter service in 2022. A Zircon was successfully test-fired from the new frigate Admiral Gorshkov in February 2020. Following the collapse of the Intermediate-Range Nuclear Forces Treaty, Putin announced the development of a ground-launched Zircon variant. The GZUR is reported to be an air-launched missile capable of a speed of Mach 6, a range of 1,500 km and sized to fit within the bomb bay of a Tupolev Tu-95MS Bear. It may enter service in the early 2020s. In this regard, Russian media reports in May noted the testing of a new hypersonic missile from a Tu-22M3 that is intended to arm the modernized Tu-22M3M. Another hypersonic missile is reported to be under development and intended to equip the Su-57. China has thus far only confirmed one hypersonic weapon, the DF-17. Its pursuit of hypersonic weapons is driven by the requirements to counter U.S. missile defenses and acquire a robust precision-strike capability as part of its wider efforts to develop “world-class” armed forces. The DF-17 is a conventionally armed medium-range ballistic missile (potentially derived from the DF-16), equipped with an HGV, with a range of 1,800-2,500 km. When it debuted at China's National Day Parade on Oct. 1, it was announced as being intended for “precision strikes against medium- and close-range targets.” In testimony before the U.S. House Armed Services Committee this March, U.S. Air Force Gen. Terrence O'Shaughnessy, commander of U.S. Northern Command and the North American Aerospace Defense Command, stated that China is testing an intercontinental HGV. It is likely that the DF-41, China's new ICBM that also debuted at the October 2019 National Day Parade, would be armed with the new HGV. O'Shaughnessy's testimony appeared to echo public statements in 2014 by Lee Fuell, who was then in Air Force intelligence and linked China's HGV development program to plans for that country's nuclear arsenal. China is developing the technologies required for HCMs. For example, in May 2018, a scramjet test vehicle, the Lingyun-1, was publicly exhibited for the first time in Beijing, while in August 2018 China successfully tested a hypersonic waverider test vehicle, the XingKong-2, which attained a speed of Mach 6. Notably, in April 2019, Xiamen University successfully flew the Jiageng-1 test vehicle, which employed a “double waverider” configuration. Interest in developing an air-launched hypersonic strike capability has also been noted. China is also believed to be developing two ALBMs, which would provide China with a near-term air-launched hypersonic strike capability. The new CJ-100, which also debuted at China's 2019 National Day Parade, warrants mention. Aside from the statement that the weapon offers “long range, high precision and quick responsiveness,” no technical information on the CJ-100 has been officially released. The South China Morning Post, citing the Chinese publication Naval and Merchant Ships, suggests the CJ-100 has a cruising speed of Mach 4 and top speed of Mach 4.5, adding that it employs a two-stage configuration utilizing a rocket booster and ramjets. Given China's progress in developing hypersonic technologies, the possibility that the CJ-100 is a hypersonic cruise missile cannot be dismissed. In a further indication of China's progress in the development of hypersonic technologies, in January 2019 it was reported that an indigenous Turbine-Based Combined-Cycle engine had completed its design and development phase and was proceeding to the aircraft integration test phase. https://aviationweek.com/defense-space/missile-defense-weapons/international-hypersonic-strike-weapons-projects-accelerate

    Air Force small business program seeks technologies to help counter COVID-19

    by Sandra Erwin In response to the SBIR solicitation, a space startup is developing a geospatial intelligence-based tool that can help governments identify infected areas. WASHINGTON — The U.S. Air Force Small Business Innovation Research office has posted a new solicitation that includes COVID-19 countermeasures as an area of interest. The March 30 Small Business Innovation Research solicitation, like most SBIR calls, is open to proposals on any topic that addresses a defense-focused need. But this is the first one that includes COVID-19 “defeat and mitigation related to Air Force operations and activities” as an area of interest. Proposals are due April 30. This SBIR is for “direct to Phase 2” contracts of up to $1 million over 27 months. Phase 1 awards are for early research work whereas Phase 2 are for technologies that are relevant to defense needs but also have commercialization potential. Some Air Force SBIR programs require matching funds from private investors. According to the March 30 solicitation, companies can compete for $1 million Air Force awards but private matching funds are not a requirement. The SBIR solicitation is an opportunity for startups in space and defense to adapt technologies for COVID-19 response, Shawn Usman, an astrophysicist with Rhea Space Activity, told SpaceNews. Usman said Rhea Space Activity has partnered with Illumina Consulting Group and Dynamic Graphics to offer a geospatial intelligence-based tool that can help governments identify infected areas much faster than is currently possible. “We can provide operational, real-time data analysis and alerting capabilities to federal, state, and military emergency operations centers,” he said. “Our solution will collect publicly available information, including social media and adware data, and correlate it with other data sets from public health organizations to create alerts detailing the emergence of COVID-19 hotspots.” Using open-source analytics and satellite collected geospatial information it would be possible to “readily confirm COVID-19 infected population areas, and will provide first responders with much more detailed, real time information to formulate their own reaction plans,” Usman said. https://spacenews.com/air-force-small-business-program-seeks-technologies-to-help-counter-covid-19/
