  SCAF : la Suède et le Royaume-Uni cherchent à rompre leur isolement

  Les ministres suédois et britannique de la Défense ont signé un protocole d'accord concernant le développement conjoint des systèmes de combat aérien du futur. Face à l'axe mis en place entre l'Allemagne, l'Espagne et la France pour développer conjointement un système de combat aérien du futur (SCAF), le Royaume-Uni et la Suède cherchent à rompre leur isolement en s'alliant. La secrétaire d'État à la Défense du Royaume-Uni, Penny Mordaunt, et le ministre suédois de la Défense, Peter Hultqvist, se sont donc rencontrés à Londres pour signer un protocole d'accord portant sur le développement d'un système similaire de combat aérien du futur (SCAF). S'étalant sur dix ans, cet accord doit permettre d'établir les conditions d'une coopération plus étroite concernant le développement d'un SCAF. Cela inclut la possibilité d'intégrer des technologies installées sur les Saab JAS 39 Gripen et BAE Systems Typhoon. Selon les parties concernées, les industriels et les gouvernements des deux pays ont identifié des besoins futurs similaires en matière de combat aérien. Le ministre de la Défense suédois, Peter Hultqvist, a souligné que les relations industrielles partagées par les deux pays étaient essentielles pour garantir cette future puissance aérienne de combat. « La coopération internationale fait partie de la stratégie de croissance de Saab et la collaboration avec les industries britanniques représente cette façon de travailler, également en prévision du futur », commente Håkan Buskhe, président de Saab. Le constructeur suédois rappelle qu'il développe actuellement le chasseur de nouvelle génération, le Gripen E/F, et qu'il « s'engage à le faire en étroite collaboration avec ses partenaires stratégiques, les forces aériennes suédoises et brésiliennes, ainsi qu'avec d'autres clients existants et nouveaux du Gripen, afin que le Gripen évolue pour répondre aux nouvelles exigences opérationnelles des prochaines décennies. » De son côté, le ministre britannique chargé des achats de la Défense, Stuart Andrew, a rappelé que le partenariat entre le Royaume-Uni et la Suède comportait déjà des exercices conjoints dans l'Arctique ainsi que l'exercice Ramstein Alloy au-dessus de l'Europe de l'Est. De même, les Typhoons de la Royal Air force sont équipés de distributeurs de paillettes et de leurres de fabrication suédoise tandis que le radar Giraffe de Saab est un élément clé du système de défense aérienne au sol britannique Sky Saber. Enfin, les Gripen sont équipés de radars conçus et construits par Leonardo à Edimbourg et le Royaume-Uni, en collaboration avec des partenaires européens, dont la Suède, a mis au point des missiles air-air Meteor. https://www.air-cosmos.com/article/scaf-la-sude-et-le-royaume-uni-cherchent-rompre-leur-isolement-21536

  Carderock Uses High-Fidelity Signature Simulation to Train Surface Combat Systems

  By Benjamin McNight III, Naval Surface Warfare Center, Carderock Division Public Affairs WEST BETHESDA, Md. (NNS) -- In the world of simulations, getting a system to act as close to authentic as the real-world situations it represents is always the main goal. Naval Surface Warfare Center (NSWC), Carderock Division develops high-fidelity acoustic simulation and training systems, giving naval personnel the ability to practice combat scenarios virtually. The Combined Integrated Air and Missile Defense (IAMD) and Anti-Submarine Warfare (ASW) Trainer, better known as CIAT, made its official debut in December 2018 at Naval Base San Diego. In June, Naval Station Norfolk became the site for another CIAT installation. Motions to create this trainer began in 2014, according to Rich Loeffler, Carderock's senior scientific technical manager, director for signatures, tactical decision aids and training systems (Code 705). “CIAT is what we refer to as a Combat Systems Team Trainer,” Loeffler said. “Meaning that your goal is to bring in the whole portion of the crew that would be operating the combat system and train them in a shore site how they can best utilize the system when they are at sea.” Carderock shares CIAT responsibilities with NSWC Dahlgren Division. Dahlgren is responsible for the overall system integration and manages the IAMD aspect of the trainer, while Carderock leads the development of the acoustic and ASW capabilities. Carderock also has capabilities that contribute to the IAMD training. Using the periscope simulation that creates a real-time visual simulation of what one could see through the periscope of a submarine, Loeffler said they were able to utilize that technology for the surface ship trainer in the CIAT. “In this case, they have deck cameras if they want to be able to see when a missile launches from the forward or aft launchers. We basically provide the visuals for that,” he said. By modeling the threats and the ocean environment and then stimulating the actual tactical combat system software, the CIAT system is highly flexible in the ability to train real-world scenarios. With the many possibilities of training situations that can be created within the CIAT comes the need to use multiple sources of knowledge to create effective training situations that will benefit the fleet. “We'll work with people like the Office of Naval Intelligence to get threat intelligence data, we'll work with folks like the Naval Oceanographic Office to get the latest environmental models and databases, and then we'll work with the tactical programs themselves to get the tactical software,” Loeffler said. “Our role here at Carderock has been to leverage signature simulation capabilities we have developed over the years across submarine, surface and surveillance ASW trainers and provide the system design, development, integration and testing support to implement the CIAT requirement to support the fleet's training needs,” he said. Before the CIAT existed, the Surface ASW Synthetic Trainer (SAST) was developed by Carderock as an on-board embedded training system within the AN/SQQ-89 A(V)15 Sonar system. Loeffler said beginning in 2008, they went through a series of large analyses to compare and contrast what the simulation produced with what operators saw at sea. The data from that testing helped further develop the SAST and subsequently create the CIAT. Now, they are able to represent all components of the operations they run from the physics modeling perspective, such as what sounds are generated and how they propagate through the water, interactions with interfering objects and sea-state effects on these variables. “Since we're acoustically stimulating the actual tactical software of the sonar system, the users are operating the systems just as they would at sea,” he said. Loeffler believes that there is not anything off limits for what the CIAT can do, but adapting with new threats will require the right development within the trainer to represent the real-world situation. Although the system is relatively new, discussions on the next steps in the development of the trainer are already taking place with the help of Center for Surface Combat Systems (CSCS) defining and prioritizing fleet training requirements “CSCS is basically the primary stakeholder that owns the surface-ship training schoolhouses, and they've done their requirements review to see what additional capabilities they'd like to see in the next version of CIAT,” Loeffler said. “So, we're going through that process, assessing those requirements and looking for what would go into the next version to further improve training and also address training of the new combat system capabilities as they are being introduced into the fleet.” https://www.navy.mil/submit/display.asp?story_id=110471
