  SCAF : la phase du démonstrateur est lancée

  Les gouvernements français et allemands ont notifié à Dassault Aviation, Airbus, MTU Aero Engines, Safran, MBDA et Thales le contrat cadre initial de démonstrateur du Système de combat aérien du futur (SCAF) Les gouvernements français et allemands ont notifié ce jeudi 13 février le contrat cadre initial de démonstrateur du Système de combat aérien du futur ou SCAF aux industriels français et allemands associés au programme. En l'occurrence, Dassault Aviation, Airbus et leurs partenaires MTU Aero Engines, Safran, MBDA et Thales. Cette notification était attendue à l'occasion du dernier salon du Bourget en juin 2019, puis avait été repoussée pour l'automne. En parallèle aux discussions serrées entre partenaires industriels sur la répartition du rôle de chacun, les gouvernements français et allemand devaient trouver un accord concernant l'exportation des systèmes, dont le SCAF. Un véritable enjeu pour les industriels impliqués dans ces programmes car leur permettant de trouver des débouchés commerciaux et de pérenniser leurs activités. Et le 16 octobre 2019, Florence Parly, ministre des Armées, pouvait annoncer : « Décision fondamentale qui acte une confiance mutuelle : un accord a été conclu aujourd'hui entre France et Allemagne. Il permet l'exportation d'équipements issus de nos coopérations. Etape essentielle pour construire sereinement une Europe de la défense ambitieuse ». Florence Parly indiquait également que le contrat visant à lancer de démonstration pour le NGF ou "New Generation Fighter" devait être signé "dès janvier 2020" et que "le premier vol devant ensuite être réalisé en 2026". « Cet avion de combat du futur et les drones qui l'accompagneront entreront dans nos forces à l'horizon 2035/2040 », avait précisé Florence Parly. Le contrat cadre notifié aujourd'hui porte sur une première phase (Phase 1A) de 18 mois et lance donc les travaux qui mèneront au développement d'un démonstrateur du NGF avec pour rappel Dassault Aviation associé à Airbus pour le NGF, Airbus et MBDA sur les "remote carriers" à la fois drones et missiles et dont le rôle sera de saturer les défenses ennemies, mener des missions de brouillage, désigner des cibles ou même larguer des missiles; Airbus et Thales sur le "combat cloud" (mise en réseau informationnelle et opérationnelle de tous les éléments du SCAF), et Safran et MTU Aero Engines sur la motorisation du SCAF. "Les entreprises concernées développeront conjointement un environnement de simulation visant à garantir la cohérence des différents démonstrateurs". https://www.air-cosmos.com/article/scaf-la-phase-du-dmonstrateur-est-lance-22559

  Air Force looks for help on new, hard-to-jam, satellite waveform

  By: Adam Stone In the face of a rising near-peer threat to electronic communications, the Air Force is pressing forward with efforts to develop a new, more resilient, harder-to-jam waveform that soldiers could use on the battlefield. The service expects to receive responses from industry soon on a recent request for information around protected satellite communications. The request sought industry guidance on how best to implement a new, more resilient protected tactical waveform (PTW), which enables anti-jamming capabilities within protected tactical SATCOM. “The Air Force is looking to protect our warfighter's satellite communications against adversarial electronic jamming,” the Air Force's Space and Missile Systems Center (SMC) said in a written statement to C4ISRNet. The threat comes from “adversarial electronic jammers that are intended to disrupt and interfere with U.S. satellite communications,” leaders at SMC said. Protected tactical SATCOM is envisioned to provide worldwide, anti-jam communications to tactical warfighters in benign and contested environments. The quest to solidify satellite communication links has taken on increasing urgency in recent years. As satellite communications has emerged as an integral component in the military's command and control infrastructure, potential adversaries have stepped up their ability to disrupt such links. “Tactical satellite communications are vital to worldwide military operations,” the agency noted. “Our adversaries know this and desire to disrupt U.S. satellite communications. The Air Force is fielding Protected Tactical SATCOM capabilities to ... ensure warfighters around the globe have access to secure and reliable communications.” Industry is expected to play a key role in the development and deployment of any new waveform. Officials at SMC said that early prototyping efforts will be conducted through the Space Enterprise Consortium (SpEC), which is managed by Advanced Technology International. SpEC acts as a vehicle to facilitate federally-funded space-related prototype projects with an eye toward increasing flexibility, decreasing cost and shortening the development lifecycle. The organization claims 16 prototype awards to date, with some $26 million in funding awarded. Understanding the protected tactical waveform Government documents describe PTW as the centerpiece of the broader protected tactical SATCOM effort, noting that it provides “cost-effective, protected communications over both military and commercial satellites in multiple frequency bands as well as broader protection, more resiliency, more throughput and more efficient utilization of satellite bandwidth.” A flight test last year at Hansom Air Force Base suggested the emerging tool may soon be ready to deliver on such promises. While SMC leads the PTW effort, Hanscom is working in collaboration with MIT Lincoln Laboratory and the MITRE Corp. to conduct ground and airborne terminal work. Researchers from MIT's Lincoln Laboratory flew a Boeing 707 test aircraft for two and a half hours in order to use the waveform in flight. With a commercial satellite, officials gathered data on the PTW's ability to operate under realistic flight conditions. “We know this capability is something that would help our warfighters tremendously, as it will not only provide anti-jam communications, but also a low probability of detection and intercept,” Bill Lyons, Advanced Development program manager and PTW lead at Hanscom, said in an Air Force news release. The test scenario called for the waveform to perform in an aircraft-mounted terminal. Evaluators were looking to see whether its systems and algorithms would function as expected in a highly mobile environment. “Everything worked and we got the objectives accomplished successfully,” Ken Hetling, Advanced Satcom Systems and Operations associate group leader at Lincoln Laboratory, said in an Air Force press release. “The waveform worked.” Asking for industry input should help the service to chart its next steps in the development of more protections. While the request does not specify when or how the Air Force intends to move forward, it is clearly a matter not of whetherthe military will go down this road, but rather when and how. https://www.c4isrnet.com/c2-comms/satellites/2018/10/05/air-force-looks-for-help-on-new-hard-to-jam-satellite-waveform/
