  The US made the wrong bet on radiofrequency, and now it could pay the price

  By: Aaron Mehta WASHINGTON – The Pentagon's belief in its technology drove the Department of Defense to trust it would have control over the electromagnetic spectrum for years to come, but that decision has left America vulnerable to new leaps in technology from China and Russia, according to a top military official. Gen. Paul Selva, vice chairman of the Joint Chiefs, has now concluded that the Pentagon needs to ensure it is keeping up with those near-peer nations, let along reestablishing dominance of electronic warfare and networking. “I think we assumed wrongly that encryption and our domination over the precision timing signals would allow us to evade the enemy in the electromagnetic spectrum. I think that was a bad assumption,” Selva said Thursday at the annual Center for a New American Security conference. “It's not that we disarmed, it's that we took a path that they have now figured out,” Selva said. China and Russia instead focused on deploying “digitally managed radio frequency manipulation, which changed the game in electronic warfare.” He added that a DoD study looking at the next decade concluded “We have some work to do.” Specifically, the United States needs to discover what Selva dubbed “alternative pathways” for communications and command and control systems. “It doesn't have to be a [radiofrequency] game. It's an RF game because we choose to make it so. And we're going to have to do some targeted investments in expanding the capacity of the networks that we use for command and control and battle management,” he said. “If we fail to do that, we're going to kick ourselves into the force-counterforce game inside the electromagnetic spectrum for the balance of the next couple of decades. “We have to adapt to that, and adapt quickly. The work has been done to characterize the problem, and the problem is, we're locked in this point-counterpoint fight with two potential competitors who have taken alternative paths. So we have to unlock a different way to do that work.” https://www.c4isrnet.com/it-networks/2018/06/21/the-us-made-the-wrong-bet-on-radiofrequency-and-now-it-could-pay-the-price/

  Silvus Technologies develops toughened waveform for US Army

  Andrew Eversden WASHINGTON — Silvus Technologies developed a new radio waveform that will make it more difficult for adversaries to intercept and detect communications signals of the U.S. Army, the company announced Aug. 13. Silvus has worked with the Army Combat Capabilities Development Command's C5ISR Center — or the Command, Control, Communication, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance Center — since last August on developing a low-probability intercept/low-probability detect (LPI/LPD) waveform. Silvus and the C5ISR Center are now exercising a six-month option period, bringing the total award to $2 million. The funding for research and development will specifically go toward work the C5ISR Center is performing on a project called “Protected Communications for Manned/Unmanned Teams.” During the option period, Silvus is integrating several new capabilities with the LPI/LPD waveform, including the ability to shift operating frequency when communications are degraded, a capability to filter out interference and a technology that allows radios to control transmission power “to enable more discreet communications.” The secure communications for the manned-unmanned teaming project is focused on “high-throughput, secure, and low observable communications capabilities for manned/unmanned teaming operations,” the Silvus news release said. The new capability “brings together a powerful suite of anti-jam and LPI/LPD functions to enable robust, secure communications for the warfighter in congested and contested environments,” said Babak Daneshrad, founder and CEO of Silvus Technologies. The new waveforms will be tested in lab evaluations starting this winter into spring 2021, according to Edric Thompson, spokesperson for the C5ISR Center. He added that field demonstrations will take place during the center's ongoing Network Modernization Experiment in 2021 and Project Convergence 2021. For fiscal 2021, it has planned soldier touchpoint events at NetModX-22 and PC22. In May, Silvus was awarded nearly $4 million to provide 1,000 of its tactical Mobile Ad Hoc radios for the Army's Integrated Visual Augmentation System program. https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/08/14/silvus-technologies-develops-toughened-waveform-for-us-army/

  L’offre française pour remplacer les F-16 laisse le gouvernement sur sa faim

  Le ministère de la Défense a réservé un accueil assez froid, voire distant, à la proposition de «partenariat approfondi et structurant» fondé sur l'avion de combat Rafale réitérée par la France à la Belgique. Une délégation de membres du cabinet de la ministre française des Armées, Florence Parly, a eu l'occasion, pour la première fois en huit mois, de venir détailler auprès de ses homologues belges, l «offre française» de partenariat «approfondi et structurant» fondé sur l'avion de combat Rafale – hors de l'appel d'offres officiel lancé en mars 2017 pour l'achat de 34 chasseurs-bombardiers de nouvelle génération. Cette rencontre a eu lieu «à la demande du Premier ministre» Charles Michel, qui souhaite disposer de tous les éléments nécessaires à une prochaine décision du gouvernement belge, a-t-on indiqué de sources gouvernementales. Mais «on n'a rien entendu de nouveau par rapport à la lettre reçue (de Mme Parly, NDLR) le 6 septembre 2017. Il n'y a rien de plus concret», a expliqué la porte-parole du ministre belge de la Défense, Steven Vandeput, Laurence Mortier. L'entourage de M. Vandeput (N-VA) a confirmé à l'agence Belga être intéressé par une éventuelle participation au programme de Système de combat aérien du futur (Scaf) européen, actuellement négocié entre la France et l'Allemagne, tout en étant ouvert à d'autres partenaires. Sur base de l'analyse des deux offres considérées comme juridiquement valables après réponse à l'appel d'offres (en jargon, un «Request for Government Proposal» ou RfGP) lancé en mars 2017, et de la – très vague – offre française, l'équipe de programme doit faire une recommandation au ministre de la Défense. Les deux candidats qui ont remis des offres en bonne et due forme sont les États-Unis avec le F-35 Lightning II du groupe Lockheed Martin et l'Eurofighter Typhoon du consortium européen éponyme. Le dossier complet, avec les aspects économiques, sera ensuite soumis au gouvernement fédéral. La Défense espère toujours une décision finale avant le sommet de l'OTAN des 11 et 12 juillet prochains, pour permettre à la Belgique d'y faire – relativement – bonne figure en dépit de ses faibles dépenses en matière de défense. http://www.lavenir.net/cnt/dmf20180516_01171480/l-offre-francaise-pour-remplacer-les-f-16-laisse-le-gouvernement-sur-sa-faim
