    US Army nears decision on who will build new missile defense radar prototypes

    By: Jen Judson   WASHINGTON — The Army is nearing a decision on who will build its Lower-Tier Air-and-Missile Defense Sensor, or LTAMDS, which will provide the sensing capability for the future Integrated Air-and-Missile Defense System the service is developing. The service is planning to award a contract no later than the end of the fiscal year to one of the three vendors that participated in a “sense-off” competition at White Sands Missile Range, New Mexico, over the spring, Daryl Youngman, the deputy director in charge of Army AMD modernization, told Defense News in a recent interview. According to other sources, that decision is expected next month. The radar is part of a new AMD system that will replace the Army’s Raytheon-made Patriot system. Raytheon, Northrop Grumman and a Lockheed Martin-Elta Systems team all brought radars to the White Sands sense-off and subsequently submitted proposals for the prototype competition in July. The winner will build six prototypes by the end of FY22 to prove whether the radar can be built and then fielded to a unit for evaluation. A follow-on contract for 16 additional radars is expected if all goes well. The plan leaves an opening for other radar solutions to get back in the game if the prototyping effort does not pan out. While the Army has dropped its long-prioritized requirement for a radar capable of detecting threats from 360 degrees, it now seeks a broader baseline requirement to “expand the battle space beyond what the current Patriot radar has,” Youngman said. And the system will ideally have a lot of growth potential baked in, he added. Replacing the Patriot radar has been a long time coming. The radar was first fielded in the 1980s, and the Army previously attempted to replace the system with Lockheed Martin’s Medium Extended Air Defense System through an international co-development effort with Germany and Italy. But that program was canceled in the U.S. after closing out a proof-of-concept phase roughly six years ago. Since then, the Army has studied and debated how to replace the Patriot radar while Raytheon continues to upgrade its radar to keep pace with current threats. It is acknowledged that there will come a point where radar upgrades will be unable to keep up with future threats. Taking years to decide, the service moved forward on a competition to replace the radar in 2017 and chose four companies to come up with design concepts for the capability — Raytheon, Lockheed Martin, Northrop Grumman and Technovative Applications. Toward the end of 2018, Raytheon and Lockheed were chosen to continue technology development under that program. Defense News first broke the news last fall that the Army was attempting to hit the reset button on the LTAMDS program, deciding to host a “sense-off” to identify available radar capabilities. While LTAMDS is considered the fourth priority out of four major lines of effort with which the Cross-Functional Team in charge of AMD has defined, it is not because it’s the least important, Youngman noted, but more related to schedule — where the system is in the development and fielding timeline. The AMD CFT’s top priority is its command-and-control system — the Integrated Battle Command System — for its future IAMD architecture. Limited user testing will occur next spring with a decision to move into production in the fourth quarter of FY20. Manuever-Short-Range Air Defense — or M-SHORAD — is the second priority as the Army . The service is set to begin development testing of its prototypes this fall. The Indirect Fire Protection Capability (IFPC) Increment 2 program is ranked third as the Army prepares to take receipt of its interim cruise missile capability — two Iron Dome Systems — soon. The Army is in the midst of coming up with a new strategy for the IFPC system that will ultimately defend against rockets, artillery and mortar as well as cruise missiles and drone threats. The IFPC system will have to tie into the Army’s IBCS system as well. https://www.defensenews.com/land/2019/08/20/us-army-nears-decision-on-who-will-build-new-missile-defense-radar-prototypes/

    Forte présence des industriels français au salon indien Defexpo 2020

    Le Pavillon France, fédéré par le Groupement des Industries de Construction et Activités Navales (GICAN) en collaboration avec le Groupement des Industries Françaises Aéronautiques et Spatiales (GIFAS), accueillera 11 entreprises sur Defexpo, salon international qui se déroulera à Lucknow en Inde du 5 au 9 février 2020. La représentation française au salon indien Defexpo est assurée par la présence de 19 entreprises représentantes de l’industrie de défense française. Il s’agit de grands groupes, mais également PME et ETI dynamiques. Cette présence marque ainsi le fort engagement de l’industrie française de la défense pour soutenir les forces armées indiennes. Les entreprises présentes sur le Pavillon France (Hall 3, stands R16 à R24, S18 et S19) sont : Arquus – Etienne Lacroix Group – Lynred – Rafale International – Rafaut Group – Roxel – RTSYS – Safran – Schneider Electric – Thales – Wartsilä Navy France. Par ailleurs, plusieurs sociétés françaises exposeront sur leur propre stand (Airbus – MBDA – Naval Group et Nexter), ou sous pavillon indien (Amphenol Interconnect – Axon’Cable – Nicomatic – Nucon Alkan – Trigo), signe de leur forte implantation dans le pays. Des rencontres entre industriels français et donneurs d’ordre indiens sont programmées tout au long de la semaine. Les industries aéronautiques, spatiales et navales françaises, rassemblées par le GIFAS et le GICAN, soutiennent la politique du «Make in India», dans les domaines de l’aéronautique, de la construction navale et de la défense. Dans cette optique, le GIFAS, le GICAN et la Society of Indian Defence Manufacturers (SIDM) organiseront un séminaire le 5 février à 15h30 dans le Seminar Hall 2. L’intention est de développer davantage le partenariat industriel entre les entreprises françaises et indiennes à tous les niveaux de la chaîne de production. Les relations stratégiques entre la France et l’Inde dans l’industrie aérospatiale sont pérennes (depuis plus de 70 ans). En 2018, une présence permanente du GIFAS en Inde a été établie à New-Delhi pour renforcer ce partenariat stratégique et développer les relations industrielles entre l’Inde et la France. En 2019, 60 membres du GIFAS sont implantés en Inde, représentant plus de 75 établissements, 20 partenariats en joint-venture et plus de 25 sites de production. https://www.aerobuzz.fr/breves-defense/forte-presence-des-industriels-francais-au-salon-indien-defexpo-2020/

  • Army to award new contracts to support mobile comms units

    Army to award new contracts to support mobile comms units

    Mark Pomerleau The Army is awarding delivery orders to three vendors to support equipment for three Expeditionary Signal Battalion-Enhanced (ESB-E) units. Specifically, the awards will support fielding of satellite baseband equipment, said Paul Mehney, director of public communications at Program Executive Office Command, Control, Communications-Tactical. Expeditionary signal battalions support units that don’t have organic communications capabilities. These groups could include military intelligence battalions, chemical battalions, engineering battalions or air defense artillery branches. The ESB-E aims to be more mobile and require less equipment in order to drop in, support units and move more quickly on the battlefield. Overall, the vendors will be responsible for providing 48 baseband sets of equipment for each ESB-E formation. “Due to aggressive initial fielding timelines, after the first six ESB-E formations are fielded, the program office intends to open baseband capability competition for future ESB-E needs,” Mehney said. PacStar was recently awarded a contract to support the ESB-E program to provide its 400-Series modular platform to enhance tactical expeditionary communications, the company said in a July 7 release. The 400-Series is lightweight allowing these smaller and expeditionary units to maneuver more quickly. It includes 128 GB RAM, virtual routing and the PacStar 463 Radio Gateway. “Network modernization to meet warfighter needs and defense priorities is a core focus for the Army and across the DoD, and we are proud to support these efforts with PacStar 400-Series for ESB-E,” Peggy J. Miller, chief executive of PacStar, said in a statement. “With these solutions, ESB-E [Scalable Network Node] will get the smallest, lightest, modular tactical communications platform in the industry, which is part of our larger initiative to enable increased reliability and innovation for warfighters.” The other vendors include Klas and DTECH, with all three supporting one ESB-E. An additional delivery order for each vendor to a second ESB-E will be issued, meaning in the near future, each vendor will support two units a piece. After that, the Army will open up the contracts to competition. This approach follows how the Army has been experimenting to date by providing similar, yet comparable equipment to several ESB-E’s. These companies have provided separate equipment to three units allowing the Army to gain useful feedback from units to see what they liked and disliked about the gear. This has allowed the Army to execute rapid prototyping and experimentation on a tighter timeline for making fielding decisions while providing equipment to soldiers in the interim. The first two ESB-Es fielded include the 57th ESB-E at Fort Hood and the 50th ESB-E at Fort Bragg. https://www.c4isrnet.com/battlefield-tech/2020/07/08/army-to-award-new-contracts-to-support-mobile-comms-units/
