    Textron Systems readies all-electric Ripsaw M5 UGV

    by Melanie Rovery Textron Systems has developed an all-electric version of the Ripsaw M5 unmanned ground vehicle (UGV). Delivery of the platform for experimentation and trials will take place in 2021. The Textron Systems-led team, selected by the US Army in January 2020, are to provide four Robotic Combat Vehicles – Medium (RCV-M) with the Ripsaw M5 offering. In addition to the baseline hybrid electric drive (HED) platform, the team will also be delivering an all-electric version called the Ripsaw M5-E. The US Army Combat Capabilities Development Command Armaments Center (CCDC, also known as DEVCOM) will receive an M5-E in a flat-deck configuration to support weapons integration testing. Deliveries will start in the second quarter of 2021. The Ripsaw M5 platform is designed and built by Textron Systems' subsidiary Howe and Howe Inc, drawing from the latter's experience in UGV and specialty vehicle development. Despite Howe and Howe's knowledge, there are common issues associated with HED and electric drive (ED) development. One concern is ensuring there is sufficient battery capacity to power the electric motors. A Textron spokesperson told Janes that the company's experience “has allowed us to continually refine our [ED] systems and incorporate these lessons learned into the M5-E, which is designed to provide an all-electric test bed for our customer”. Future challenges for the HED/ED include electric efficiency and charge rates. Textron believes this will be mitigated by improved technology. “Our current solution leverages increased fuel efficiency and is enabled by agile logistics, ensuring adequate fuel is available,” the spokesperson explained. https://www.janes.com/defence-news/news-detail/textron-systems-readies-all-electric-ripsaw-m5-ugv

  • Budgets Défense : les doutes du député Cornut-Gentille

    Budgets Défense : les doutes du député Cornut-Gentille

    Jean-Marc Tanguy Le député de la Haute-Marne, rapporteur spécial pour la défense à la Commission des finances de l'Assemblée Nationale a, une fois de plus, transmis ses doutes sur le projet de loi de finances (PLF) 2021. Surcoûts Opex Le député (LR) de la Haute-Marne, rapporteur spécial pour la défense à la Commission des finances de l'Assemblée Nationale, a une fois de plus transmis ses doutes, ce 13 octobre, sur la fin de gestion 2020, et le projet de loi de finances (PLF) 2021, qui sera étudié en première lecture dans l'hémicycle à la fin du mois. François Cornut-Gentille estime que la « fin de gestion 2020 sera compliquée comme tous les ans, mais un peu plus en 2020 » du fait de l'augmentation des surcoûts Opex liés aux 600 personnels déployés en plus à Barkhane (mais aussi aux pertes en matériels), aux opérations Résilience et Amitié. Ainsi, le niveau pourrait atteindre 1,6 Md€, estime l'élu. Dassault Rafale pour la Grèce Auparavant, le ministère des Armées trouvait des ressources pour financer ces surcoûts : les montants non dépensés du titre 2 par exemple, mais le député estime que la totalité des fonds du T2 seront dépensés cette année. Le report de charge, qui aurait dû se réduire dans le cours de la LPM, progresse, constate François Cornut-Gentille, et pourrait atteindre 15 à 16 %. Le député se félicite aussi des annonces grecques sur le Dassault Rafale, « une bonne nouvelle pour les exportations et pour Dassault Aviation » mais il s'inquiète comme beaucoup des conséquences du prélèvement des 12 Dassault Rafale dans l'Armée de l'Air. Et du fait qu'il va falloir inscrire environ un milliard d'euros non prévus en LPM au chapitre des dépenses. Certes, la Grèce va payer pour les appareils d'occasion (sur lesquels en sus il faudra enlever des équipements/ndlr), mais moins que pour des avions neufs. Definvest pas à la hauteur ? Et la ministre des Armées, Florence Parly, elle-même reconnaissait en commission il y a peu qu'elle n'était pas sûre de récupérer le produit de cette vente même si elle entend obtenir gain de cause avec Bercy. Le niveau du reste à payer, les engagements non couverts par des paiements, atteint les 72,7 MdEUR à la fin 2019, un plus haut historique depuis 2006 au moins. François Cornut Gentille veut aussi dynamiser la logique de Definvest, qui n'a réalisé « que huit opérations » et « n'est pas à la hauteur des enjeux ». Photonis n'a pas été suffisamment protégé, constate-t-il. Enfin, il a déploré l'absence de réponses du ministère des Armées à ses 150 questions budgétaires posées en juillet en vue du PLF2021, ou des réponses trop tardives : 50 sont arrivées au courrier ce samedi. D'autres réponses, enfin, sont accompagnées d'une demande de discrétion, alors qu'elles figurent par ailleurs... en source ouverte, dans d'autres documents budgétaires. https://www.air-cosmos.com/article/budgets-dfense-les-doutes-du-dput-cornut-gentille-23737

  • US Navy awards largest-ever shipbuilding contract to Electric Boat for new attack submarines

    US Navy awards largest-ever shipbuilding contract to Electric Boat for new attack submarines

    By: David B. Larter WASHINGTON – The U.S. Navy on Monday awarded its largest-ever shipbuilding contract to General Dynamics Electric Boat for construction of nine Virginia-class attack submarines, eight of which will have 84-foot section that boosts the boat's strike missile capacity. The contract for the Block V Virginias, worth $22.2 billion, could grow by another $2 billion if the Navy exercises an option for a 10th boat. The contract is for two fewer boats than the 11 proposed by the fleet in this year's budget submission. “A lot of hard work across the whole team to structure the contract in such a was as to balance risk between the government and the shipbuilder,” said James Geurts, the Navy's top acquisition official, in a roundtable with members of the media to announce the contract signing. “If the shipbuilder delivers on target, the multi-year savings will be 16.5 percent, or $4.4 billion in savings. So, it's a pretty important day for us.” Guerts, the assistant Secretary of the Navy for research, acquisition and development, said that when you add government furnished equipment into the contract, the total swells to about $35 billion. The first boat in Block V, SSN 802, is currently under construction but does not have the Virginia Payload Module. The next boat, 803, will have VPM. All of the boats will have an upgraded acoustics suite. In the briefing, Navy officials said that six of the boats would be constructed at Electric Boat's partner yard, Huntington Ingalls Newport News, and three would be built at Electric Boat. The 10th boat would go to Electric Boat if the Navy exercised the option. The move to put most of the work in Newport News was done to balance the increased workload at Electric Boat with the start of the Columbia class, the next generation of ballistic missile submarines slated to begin construction this year. In a statement, Electric Boat President Kevin Graney said the contract provides stability for his shipyard. “This contract allows for our shipbuilding team, out suppliers and our employees to plan ahead so that we can continue to deliver submarines of unmatched quality, stealth and lethality,” Graney said. Dave Bolcar, Newport News' vice president of submarine construction, likewise hailed the contract as a means of stability in the submarine industrial base. "Today's contract maintains the Virginia-class build rate that provides continued stability to our workforce and to the 5,000 suppliers that will support submarines for the next decade,” he said. "This contract also continues the two per year construction cadence essential to sustaining production efficiencies, while ensuring our national security and the Navy's continued undersea superiority.” https://www.defensenews.com/naval/2019/12/02/navy-awards-largest-ever-shipbuilding-contract-to-electric-boat-for-new-attack-submarines
