  The Army is looking for a new all-around vehicle that can swim, climb and charge through snow

  By: Todd South After more than 40 years of service, the robust little all-terrain vehicle that can climb mountains, ford rivers and churn through snow needs replacing. And the Army, Marines and National Guard are asking industry to give them a new ride. Back in June, Army Contracting Command officials put out a Request for Information for industry to share what they think can replace the Small Unit Support Vehicle, a tracked vehicle that's been in service since the mid-1970s. At one point, there were 1,100 of them in the U.S. military inventory. Now, only a few dozen remain, mostly in service in cold weather areas such as U.S. Army Alaska. The new program to replace the SUSV has been dubbed the “Joint All Weather All Terrain Support Vehicle," or JAASV. So far, Army officials have only asked for information, but they are expected to issue a proposal with more detailed requests for requirements and timelines from industry in the coming weeks or months. The upgrade and replacement are important for a variety of reasons, some of which are near-term, such as National Guard disaster response to blizzards, floods and fires, which can't be navigated easily by the current Humvee fleet. Others are for mobility in the Arctic. Leaders are shifting training and resources back to the Arctic as Russia has beefed up its capabilities and manpower in the region in recent years, from new units and commands to upgraded equipment and weaponry. BAE Systems built the original SUSV, or Bv206, and has since built a modernized version called the BvS10 in both armored and unarmored types. The newer model has been fielded to military units in the United Kingdom, Norway, France and the Netherlands. It has seen real-world operations in Afghanistan and the Balkans on NATO missions, according to company officials. Last year, ST Kinetics unveiled its own version of a small, all-terrain tracked vehicle, called the Bronco 3, at DESI, a defense conference in London, England, according to Army Times sister publication Defense News.

  Extending Field of View in Advanced Imaging Systems

  New program focuses on developing curved infrared focal plane arrays to improve optical performance and widen field of view while reducing system size of military imagers The military relies on advanced imaging systems for a number of critical capabilities and applications – from Intelligence, Surveillance, and Reconnaissance (ISR) and situational awareness to weapon sights. These powerful systems enable defense users to capture and analyze visual data, providing key insights both on and off the battlefield. Today, nearly all imaging systems rely on detector arrays fabricated using planar processes developed for electronic integrated circuits on flat silicon. While significant progress has been made in advancing these technologies for narrow field of view (FOV) systems, optical aberrations can limit the performance at the periphery in wide FOV systems that then require large, costly, and complex optics to correct. The trade-off for correcting optical aberrations by using large, heavy lenses is a reduction in optical signal and a large size penalty, which limits their use for new and emerging capabilities. “Tremendous progress has been made over the past 20 years towards making multi-megapixel infrared (IR) focal plane arrays (FPA) for imaging systems cost effective and available to the Department of Defense,” said Dr. Whitney Mason, a program manager in DARPA's Microsystems Technology Office (MTO). “However, limitations to the technology's performance and size remain. Current advances on the commercial side have shown the viability of small area, curved FPAs (CFPAs) for visible cameras. While these technologies have shown modest benefits, more must be done to achieve the performance and size requirements needed for imaging systems used in emerging defense applications.” DARPA developed the FOcal arrays for Curved Infrared Imagers (FOCII) program to expand upon the current commercial trend for visible sensor arrays by extending the capability to both large and medium format midwave (MWIR) and/or longwave (LWIR) infrared detectors. The program seeks to develop and demonstrate technologies for curving existing state-of-the-art large format, high performance IR FPAs to a small radius of curvature (ROC) to maximize performance, as well as curve smaller format FPAs to an extreme ROC to enable the smallest form factors possible while maintaining exquisite performance. FOCII will address this challenge through two approaches to fabricating a curved FPA. The first involves curving existing state-of-the-art FPAs, while keeping the underlying design intact. The focus of the research will be on achieving significant performance improvements over existing, flat FPAs, with a target radius of curvature of 70mm. The fundamental challenge researchers will work to address within this approach is to mitigate the mechanical strain created by curving the FPGA, particularly in silicon, which is very brittle. The second approach will focus on achieving an extreme ROC of 12.5 mm to enable a transformative reduction in the size and weight compared to current imagers. Unlike the first approach, researchers will explore possible modifications to the underlying design, including physical modifications to the silicon that could relieve or eliminate stress on the material and allow for creating the desired curvature in a smaller sized FPA. This approach will also require new methods to counter the effects of any modifications during image reconstruction in the underlying read-out integrated circuit (ROIC) algorithm. The FOCII program is hosting a proposers' day on August 13, 2019 at the Executive Conference Center, 4075 Wilson Blvd., Suite 300, Arlington, Virginia, 22203 from 9:00 a.m. to 4:00 p.m. EDT. The purpose of this meeting is to provide information on the FOCII program, promote additional discussion on this topic, address questions from potential proposers, and provide an opportunity for potential proposers to share their capabilities and ideas for teaming arrangements.

  Le drone Patroller maritime de Safran prouve sa maturité lors de la démonstration finale du projet OCEAN2020

  Safran Electronics & Defense annonce que son drone Patroller a « montré sa capacité à répondre à des besoins de surveillance maritime au profit de Marines nationales ou d'agences européennes de surveillance maritime », dans le cadre du projet européen OCEAN2020 financé par la Commission Européenne au titre de l'Action Préparatoire de Recherche de Défense. Des exercices navals ont été organisés en mer Baltique, à la fin du mois d'août, rassemblant 18 partenaires dont 5 Marines nationales pour la démonstration finale OCEAN2020, ayant pour objectif de « montrer que l'emploi combiné de drones de tous milieux (aériens, de surface et sous-marins) fournit une meilleure perception de la situation tactique maritime au commandement », précise Safran.
