    Naval Group shares its industrial vision with the submarine community and broadens strategic partnership at NEDS

    28 November 2019 On November 28th 2019, Naval Group participates to the Defence & Security exhibition held at Rotterdam AHOY. During this event, Naval Group shares its vision on the development of the submarine community in the Netherlands. The project will generate a workload of 15 million man/hours and is expected to create over 2000 jobs in the Netherlands. In view of the Walrus capability replacement programme, Naval Group demonstrates their will to commit to a full submarine IP and knowledge-sharing with the Dutch knowledge centers and industry. This will empower the Netherlands submarine community to take part in the future design and build phase, thus reinforcing the existing knowledge and leading to an autonomous maintenance and upgrade of the submarine. Naval Group has successfully adopted this methodology in Australia, which is leading to the development of a game-changing capacity with a Barracuda-family submarine which offers outstanding acoustic superiority as well as expeditionary capabilities. Naval Group's vision of the future submarine project. “What is at stake in this project is not industrial workload for Naval Group in France-as our submarines factories will be quite busy along the next decades-but the European cooperation within the maritime industry of our two countries. Beyond the industrial workload which will be transferred to the Netherlands, Naval Group is totally committed to support the Netherlands in remaining fully autonomous on operational, strategical and technological aspects on the long- term basis.” declared Hervé Guillou during NEDS. With all the complexities and long lead-time involved in a submarine project, it is crucial to determine how strategic knowledge and expertise is shared, used and maintained over a period which exceeds thirty years. Defining all the required technical and operational trade-offs based on a value-mapping process through an in-depth dialogue with the client is key to reach the best possible submarine platform. For this purpose, Naval Group has released its plan for the future submarine design and production ecosystem at NEDS. One of the key features of Naval Group's vision to organize transfer IP rights and design authority to the Netherlands, which effectively will deliver to local industry and knowledge centers an in-depth understanding and mastering of the selected design. The submarine project will see the reinforcement of a submarine community whose contribution and expertise will grow over the years when key upgrades or changes are implemented on the chosen design. In this process, Naval Group has already qualified 30 new companies to be Tier 1 and 2 suppliers for this programme and other international programmes. In February 2019, Naval Group announced the partnership with Royal IHC. The two companies brought their complementary experience and expertise in designing and manufacturing complex maritime and defense systems together in order to offer the best submarine to the Netherlands and fully comply with the Defense Industrial Strategy (DIS). In continuity to this important first step, Naval Group now unveils one of its strategic partnerships: the teaming agreement with Contour, whose team possesses a comprehensive experience in providing simulation and digital training tools for the Netherlands MOD and notably the Royal Netherlands Army. Their expertise will allow modern simulation tools to be deployed to ease the crew's training period before the actual submarine is sent on trials. Using the Dutch world-class maritime ecosystem, Naval Group has identified more than 30 partners in the country partners of excellence which can provide critical systems and components for submarine and surface ships programmes alike. The submarine community will remain a center of excellence where the best Dutch expertise will be sustained.This ambitious industrial cooperation program is expected to generate over 2000 jobs, which represent 15 million man-hours, for the Netherlands economic growth during the design and build phase. Most of this capabilities will then be used for decades for through-life support. “Naval Group deliberately involves local partners in its international activities. The purpose of these agreements is to pool a Dutch submarine community for the Netherlands would Naval Group be selected for the Walrus replacement program. Key to a successful cooperation is a know-why methodology and a true IP and know-how repository to build-up and contribute that unique expertise, which will support in the long-term both the Netherlands' but also international submarine programmes” declared Mark van Rooij, Naval Group Netherlands CEO. A long-term commitment towards the Dutch industry The Dutch ecosystem has long been a partner with Naval Group on several major programmes; since 2013, a volume of 200 million euros contracts has been awarded to Dutch industrial and knowledge partners covering both French and international programmes. At NEDS, Naval Group deepens existing bonds with the Dutch maritime and defense industry, building and expanding existing relationships with more than 70 companies and knowledge institutes. The latest Naval Group surface ship (FDI) benefits from key Dutch technologies. Rubber Design has developed and supplied silencing elastic mounts to help reduce the ship's acoustic signature, whilst MAFO's door systems have been conceived as Radar Cross Signature reduction devices. Naval Group Netherlands, the Dutch subsidiary established in 2018 has played a significant role in the reinforcement of these long-term relationships. Sliedrecht-based company DBR has just been selected to supply key propulsion equipment on Naval Group's latest international ship programme. The company, well-known in the maritime industry, will for the first time enter the naval military market with this contract. For the Belgium-Dutch Mine Counter Measure Vessels program, several Dutch actors are about to be consulted. For instance, Dutch knowledge center Marin has already been selected by Naval Group in 2019 to test and improve its latest hull design, delivering improved hydrodynamic capabilities along with better energy-efficiency. For this program, other domains will be opened to Dutch competitors such as IPMS (Integrated platform management system), IBNS (Integrated Bridge Navigation System), radar, ventilation, firecontrol, speedboats and handling systems.

    Bringing Photonic Signaling to Digital Microelectronics

    DARPA program seeks to unleash the performance of modern multi-chip modules by integrating optical signaling at the chip-level OUTREACH@DARPA.MIL 11/1/2018 Parallelism – or the act of several processors simultaneously executing on an application or computation – has been increasingly embraced by the microelectronics industry as a way of sustaining demand for increased system performance. Today, parallel computing architectures have become pervasive across all application domains and system scales – from multicore processing units in consumer devices to high-performance computing in DoD systems. However, the performance gains from parallelism are increasingly constrained not by the computational limits of individual nodes, but rather by the movement of data between them. When residing on modern multi-chip modules (MCMs), these nodes rely on electrical links for short-reach connectivity, but once systems scale to the circuit board level and beyond, the performance of electrical links rapidly degrades, requiring large amounts of energy to move data between integrated circuits. Expanding the use of optical rather than electrical components for data transfer could help significantly reduce energy consumption while increasing data capacity, enabling the advancement of massive parallelism. “Today, microelectronic systems are severely constrained by the high cost of data movement, whether measured in terms of energy, footprint, or latency,” said Dr. Gordon Keeler, program manager in DARPA's Microsystems Technology Office (MTO). “Efficient photonic signaling offers a path to disruptive system scalability because it eliminates the need to keep data local, and it promises to impact data-intensive applications, including machine learning, large scale emulation, and advanced sensors.” Photonic transceiver modules already enable optical signaling over long distances with high bandwidth and minimal loss using optical fiber. Bottlenecks result, however, when data moves between optical transceivers and advanced integrated circuits in the electrical domain, which significantly limits performance. Integrating photonic solutions into the microelectronics package would remove this limitation and enable new levels of parallel computing. A new DARPA program, the Photonics in the Package for Extreme Scalability (PIPES) program, seeks to enable future system scalability by developing high-bandwidth optical signaling technologies for digital microelectronics. Working across three technical areas, PIPES aims to develop and embed integrated optical transceiver capabilities into cutting-edge MCMs and create advanced optical packaging and switching technologies to address the data movement demands of highly parallel systems. The efficient, high-bandwidth, package-level photonic signaling developed through PIPES will be important to a number of emerging applications for both the commercial and defense sectors. The first technical area of the PIPES program is focused on the development of high-performance optical input/output (I/O) technologies packaged with advanced integrated circuits (ICs), including field programmable gate arrays (FPGAs), graphics processing units (GPUs), and application-specific integrated circuits (ASICs). Beyond technology development, the program seeks to facilitate a domestic ecosystem to support wider deployment of resulting technologies and broaden their impact. Projections of historic scaling trends predict the need for enormous improvements in bandwidth density and energy consumption to accommodate future microelectronics I/O. To help address this challenge, the second technical area will investigate novel component technologies and advanced link concepts for disruptive approaches to highly scalable, in-package optical I/O for unprecedented throughput. The successful development of package-level photonic I/O from PIPES' first two technical areas will create new challenges for systems architects. The development of massively interconnected networks with distributed parallelism will create hundreds to thousands of nodes that will be exceedingly difficult to manage. To help address this complexity, the third technical area of the PIPES program will focus on the creation of low-loss optical packaging approaches to enable high channel density and port counts, as well as reconfigurable, low-power optical switching technologies. A full description of the program is available in the Broad Agency Announcement.

    Leidos awarded $72.8M for Navy's TRAPS sub detection system

    By Ed Adamczyk June 24 (UPI) -- Leidos Inc. was awarded a $72.8 million contract for work on submarine detection sonar for the U.S. Navy, the Defense Department announced. The company, based in Reston, Va., will perform work on the Transformational Reliable Acoustic Path System, or TRAPS, one of two prototypes developed by the Defense Advanced Research Projects Agency, the Defense Department agency responsible for the development of emerging technologies military applications. Leidos' Leidos' work on TRAPS comes under an indefinite quantity, cost-plus-fixed-fee contract with a three-year ordering period and no options, the Defense Department announced on Friday. The TRAPS system uses a fixed sonar mode placed on the ocean floor, exploiting advantages of operating from the seafloor, to achieve large-area surveillance of the area surrounding the submarine. Each node communicates back to a floating "stationary surface node" through a wireless acoustic modem when the ocean floor node detects a sound. The other prototype, called Submarine Hold at Risk [SHARK], has an unmanned underwater vehicle as a mobile platform to track enemy submarines. Both are part of DARPA's Distributed Agile Submarine Hunting [DASH] program. Leidos' work on the contract will be done at the company's Long Beach, Miss., facility, with an expected completion date of June 2022. https://www.upi.com/Defense-News/2019/06/24/Leidos-awarded-728M-for-Navys-TRAPS-sub-detection-system/9201561393132/
