    DIU Seeks Prototype Sat Terminal For Army All-Domain Ops

    The mobile TITAN satellite ground station is a critical node in Army plans for all-domain operations. By THERESA HITCHENS WASHINGTON: The Defense Innovation Unit (DIU) wants commercial vendors to submit prototypes for the Army's planned mobile ground station that can fuse sensor data from multiple ISR satellites — including both national security and commercial — into a common operational picture for battlefield commanders. While this solicitation, released late yesterday, focuses on space-based sensors, ultimately the Tactical Intelligence Targeting Access Node (TITAN) is envisioned as a “unified” ground station that can take data not just from satellites, but also from high-altitude, aerial and terrestrial ISR sensors to provide targeting data directly to Army Long-Range Precision Fires (LRPF) networks. The Army describes TITAN as a “scalable and expeditionary intelligence ground station.” It is envisioned as a critical enabler of Army all-domain operations command and control. The satellite terminal is the first step in what will be a modular development of the TITAN terminal's capabilities over time — with a goal to deploy and initial operating capability early in fiscal 2022, as Brig. Gen. Rob Collins, Army program executive officer for intelligence, electronic warfare and sensors, explained at the giant Association of the United States Army (AUSA) show in October, DIU's Space Portfolio Director Steve Butow explained in an email that the prototype ground stations should be “capable of rapidly and semi-autonomously tasking, receiving, processing, exploiting, fusing, and disseminating space based sensor data to provide networked situational awareness and direct tactical support to Army commanders at echelon.” One of the key goals is “to reduce sensor to shooter latency.” Latency is the term of art to describe the time it takes to send information from the satellite to the user on the ground. The prototype ground stations — which as with all DIU projects are envisioned to be rapidly fielded — must be capable of “rapid deployment to diverse operational environments via strategic lift and once deployed, be capable of rapid setup, tear down, movement, and assembly to meet operational commander's needs.” They also must be able to function “for a reasonable period of time” through “any loss of non-local communications or networks.” American contractors have until April 3 to put forward a proposal. Proposed prototypes “should include everything required to operate during a designated exercise(s) and demonstration(s) as well during real world operations, including the vehicle/trailers, power generation/conditioning, antennae, communications/network hardware/software (to include line of sight and beyond line of sight), processing hardware/software, and analytical hardware/software,” the solicitation states. Further, prototypes should be able to store and process data from multiple commercial providers. This means that the “access node should be a modular, open systems architecture, making it easy to upgrade software/firmware, analytics/algorithms, and ingest additional data streams as commercial vendors and national data become available.” This includes being able to store and process both classified and unclassified data. The project will run for 24 to 30 months, and will include the delivery of at least two and as many as six working prototypes. They must be ready for immediate testing and evaluation in a theater exercise. DUI is looking at two phases. Phase 1 includes the “development, integration, testing, accreditation and delivery” of two prototypes by January 2022. Phase 2 “includes the testing, assessment, and refinement of the prototype systems based upon participation in and feedback from several exercises and evaluations,” both in the US and theaters abroad. Phase 2 also includes the option of delivering up to four additional prototype systems. DIU generally uses Other Transaction Authorities as a contracting vehicle, as will this program. The solicitation notes that DoD is “also pursuing a separate parallel effort for the objective TITAN ground station design to accommodate Aerial and Terrestrial sensors as well.” Thus, the contractor(s) chosen will need to work ensure designs for the satellite terminal can be integrated with, and that all the software is transportable to, that design via agreements with the other companies involved. The Army issued a Request for Information on Dec. 4 about technologies to enable the “objective” TITAN terminal that can integrate all types of ISR sensors. That RFI was updated on Dec. 18. The RFI explains that TITAN eventually will replace the Army's current Tactical-Intelligence Ground Station, Operational-Intelligence Ground Station, Advanced Miniaturized Data Acquisition System Dissemination Vehicle and Remote Ground Terminal. It also must be “to operate at Brigade, Division, Corps, and Field Army echelons, in vehicles and shelters organic to the formation,” the solicitation said. According to a Q&A transcript of the Army's Dec. 4 industry day on TITAN, the service currently sees potential deployment platforms: a larger version for integration with on one variant of the Family of Medium Tactical Vehicles (FMTV) with a shelter; and a smaller one to be integrated on “a four-seater tactical vehicle — either a Joint Light Tactical Vehicle (JLTV) or a Humvee. What is unclear is how this DIU effort relates to the earlier sole-source award to Peraton for the Satellite Ground Terminal (SGT) Prototype, that on the face of it is being designed to do exactly the same thing. Under that Nov. 19 award, which supports the Army's Tactical Exploitation of National Capabilities (TENCAP) program, Peraton was to develop a fully-tested prototype to the Army within 20 months. SGT is expected to transfer up to 1,000 times more satellite data to operators than currently possible, according to Peraton. Queries to the Army, DIU and Peraton about this were not answered at press time. https://breakingdefense.com/2020/03/diu-seeks-prototype-sat-terminal-for-army-all-domain-ops

    Le porte-avions «Charles-de-Gaulle» reprend la mer comme neuf

    Nicolas Berrod Après deux années de rénovation, le « Charles-de-Gaulle », à nouveau opérationnel, s'apprête à reprendre la mer. Nous avons pu passer 48 heures à bord, au côté de l'équipage, actuellement en pleine phase d'entraînement. « Wave off ! » Le cri de l'officier résonne sur le pont d'envol pour signifier à tout le monde de... « dégager ». Bienvenue à bord du « Charles-de-Gaulle », le seul porte-avions de la marine française, qui vient de subir un lifting intégral d'une durée de deux ans, pour un coût total de 1,3Mds €. Avant de repartir en mission dans quelques mois, ce mastodonte de 42 000 t pour 261 m de long poursuit ses entraînements au large de Toulon, son port d'attache. « On était orphelins, le Charles-de-Gaulle nous a manqué », sourit Christophe, capitaine de frégate et chef des pilotes. Avec ses collègues, ils ont eu beau s'être entraînés sur piste classique et sur un porte-avions américain le temps de la rénovation, rien ne vaut à leurs yeux le prestige du bateau français, en service depuis 2001. Le « Charles-de-Gaulle » aura un successeur, a assuré Emmanuel Macron, lorsqu'il sera mis hors service vers 2040. Coût estimé : minimum 3 Mds€. Et durée de la construction : 15 ans... au moins ! Chiens jaunes Alors, en attendant, la France compte sur son unique porte-avions, véritable village flottant de 2000 habitants - un équipage de 17 à 55 ans, dont 140 officiers de pont, 300 techniciens, 33 cuisiniers, 2 boulangers, 17 % de femmes au total. Après 18 mois passés à la cale, il faut le remettre en service. D'où, en cette fin d'automne, un entraînement intensif en Méditerranée, à quelques dizaines de kilomètres des côtes françaises. Entre quatre et vingt Rafales (NDLR : avions de combat) sont catapultés trois fois par jour, décollant sur une piste d'à peine quelques dizaines de mètres. Au signal des « chiens jaunes », ces officiers de pont reconnaissables à leur gilet coloré, les avions atteignent en quelques secondes les 200 km/h. Ce lundi-là, une poignée de jeunes pilotes - entre 22 et 26 ans - effectuent leur baptême de vol sur le « Charles-de-Gaulle ». Pour pouvoir manœuvrer sur un porte-avions, il leur faut avoir un minimum de 100 heures de vol sur Rafale. « On porte une attention toute particulière à ces jeunes », glisse, l'œil rivé à la piste, Jean-Philippe, chef des « chiens jaunes ». À l'issue de leur vol - ce jour-là dans un ciel dégagé -, ces pilotes doivent accrocher l'un des trois brins d'arrêt situés sur la piste pour apponter. Ces épais c'bles qui stoppent le Rafale d'un coup sont indispensables sur une piste aussi courte. « C'est comme si on pilait sur autoroute », glisse un officier, qui scrute à l'horizon les premiers avions sur le retour. Paradoxalement, au moment de toucher le pont à 250 km/h, les pilotes doivent remettre les gaz à fond. Car, s'ils ratent les brins, il faut pouvoir redécoller à temps ! « On appelle ça un bolter, c'est un peu un bizutage pour les nouveaux », sourit l'expérimenté capitaine Christophe, 2000 heures de vol sur Rafale derrière lui.
