Le missile Air-Air très longue portée russe R37M entrera bientôt en service
FABRICE WOLF
Avec plus de 4000 avions de combat modernes de tout type, l'OTAN dispose de la plus formidable force aérienne au monde, très supérieure aux forces russes (1300 appareils) et chinoises (1500 appareils).
Consciente qu'elle ne pourra jamais rivaliser numériquement avec cette force, la Russie a développé une stratégie de défense aérienne multi-couches reposant sur des systèmes de défense anti-aérienne à longue, moyenne et courte portée, intégrée dans un réseau global et coordonnant ses actions avec l'importante flotte de chasseurs russes de plus de 800 appareils Su27-30-35 et MIG-29, et les 130 intercepteurs MIG-31. Ainsi organisée, la défense anti-aérienne russe représente un challenge important pour les forces aériennes occidentales, qui doivent utiliser des avions de brouillage ou des appareils furtifs pour espérer garder la supériorité aérienne.
Pour articuler cette puissance aérienne, qui représente aujourd'hui 80% de la puissance de feu de l'Alliance selon le British Defense Comittee, l'OTAN déploie un nombre important d'appareils de veille aérienne AWACS, de surveillance électronique, et une flotte massive d'avions ravitailleurs.
Le missile à longue portée hypersonique R37M a été développé pour engager et abattre ces appareils, avec une portée supérieure à 300 km et une vitesse supérieure à Mach6. Destiné à équiper les intercepteurs rapides MIG-31 et les chasseurs lourds furtifs Su-57, le R37M permettra de repousser les appareils de soutien de l'OTAN très loin de la zone d'engagement, limitant de fait très sensiblement leurs performances. Un appareil qui, comme le F-35 américain, n'a qu'un rayon d'action de 1000 km, sera ainsi largement contraint s'il doit se ravitailler à 500 km de ses objectifs. En outre, les forces russes auront la possibilité de mener des « raids tactiques », des incursions rapides destinées à porter le danger au plus profond du dispositif adverse, suivi d'un retour rapide dans la zone de supériorité alliée. Au delà des AWACS et ravitailleurs, le nouveau missile menacera donc l'ensemble des appareils lourds de l'alliance atlantique, incluant les avions de transport en charge du train logistique transatlantique indispensable, ainsi que les appareils de patrouille maritime, surtout ceux évoluant à moyenne altitude comme le P8 Poséidon, très exposés dès qu'ils évolueront à moins de 2000 km d'une base aérienne russe.
Les mêmes causes ayant les même conséquences, la Chine a elle-aussi développé un missile à très longue portée, estimée à 400 km, et destiné à abattre les appareils de soutien occidentaux. Le nouveau missile, dont la nomenclature est encore floue, a déjà été aperçu sous les ailes des J-11 et des J-16 de l'Armée Populaire de Libération.
Ce type de missile n'a pas d'équivalent en Occident. En effet, les forces aériennes chinoises et russes dépendent beaucoup moins des appareils de soutien que leurs homologues occidentaux. En revanche, les états-majors de l'OTAN ont privilégié des missiles d'une portée inferieure, de l'ordre de 150 km, mais très efficaces contre les agiles chasseurs adverses, comme le missile européen Meteor.
L'entrée en service du R37M devra donc engendrer une rapide évolution des doctrines aériennes de l'OTAN, comme dans la conception des appareils lourds, qui devront nécessairement être équipés de systèmes d'autodéfense performants capables de détecter, brouiller et leurrer de tels missiles.

United States Marine Corps Procures the New InstantEye Mk-3 GEN5-D1 SUAS System
ANDOVER, Mass., Nov. 20, 2018 /CNW/ -- InstantEye Robotics is pleased to announce it has secured a contract with the Defense Logistics Agency (DLA) in support of PMA-263, the Navy and Marine Corps Small Tactical Unmanned Aircraft Systems (SUAS) Program Office, to field 32 InstantEye Mk-3 GEN5-D1 SUAS systems (64 aircraft). This procurement is being executed in support of a United States Marine Corps urgent needs request for field user evaluation. The new InstantEye Mk-3 GEN5-D1 platform expands mission scope and provides additional Reconnaissance, Surveillance, and Target Acquisition capability to the individual Marine or Sailor. "We are very excited to start fielding the first system in our new InstantEye Mk-3 line of products, which is designed to further strengthen the security of our SUAS products as well as expand the capabilities and features of our systems," said Tom Vaneck, Vice President of InstantEye Robotics. "The Marines have been great supporters of the InstantEye systems, and we think the InstantEye Mk-3 GEN5 system will greatly complement their existing portfolio and enhance force protection while reducing operational risk." The InstantEye Mk-3 GEN5-D1 is the smallest (~250g) in the InstantEye family of combat-proven, high-performance, affordable systems. It is an encrypted, all-digital system with superb real-time video and still imagery. Due to its small size, it has low audible and visual signatures, enabling it to operate undetected in close proximity to targets of interest. The system requires only a single operator and goes from a stowed configuration to fully operational in approximately one minute. With an ability to operate in all weather and locations, it is an unmatched tactical enabler with operational effects. InstantEye Robotics is a division of Physical Sciences Inc., both located in Andover Massachusetts. InstantEye Robotics is a global leader in tactical unmanned aircraft systems. When customers need a reliable, portfolio-manageable, multi-mission system, they choose InstantEye.

Pegasus Imagery: Imagining a smarter future
by Tania Moffat Initially created to provide intelligence, surveillance, and reconnaissance solutions for the military, drone technology has had difficulty transitioning to commercial use. Military drones are not well-suited to interact with civilian aircraft and consumer models do not have the necessary range or technology. Alberta-based Pegasus Imagery believes it has bridged the technology gap between military and consumer applications. The company provides real-time intelligence and data solutions at scale to the emergency management, public safety and energy sectors. Owner Cole Rosentreter became an entrepreneur after a parachuting accident cut his decorated 15-year military service short. A paratrooper with the Princess Patricia's Canadian Light Infantry (PPCLI) he actively served on several deployments, including three in Afghanistan. During his tours, he witnessed how drone technology was able to help soldiers work safer, smarter and more effectively. “It was a natural choice to make my next mission to support the guys on the front lines here at home,” he said. Bridging the tech gap Hyperion, the company's long-range drone, was designed to deliver continual airspace awareness during flight and to deliver these solutions at scale. It is based on two prototypes used in commercial contracts earlier this year for the Alberta government, law enforcement, conservation and the energy sector. The aircraft is capable of carrying multiple sensors on a single flight, including connected voice and data comms. In addition to its ability to supply thermal imaging and aerial mapping, it is equipped with military-grade sensors and communications equipment, able to capture and deliver real-time electro-optical and infrared video through a secure connection. “We build our own drones to meet the needs of the market. All of our aircraft are manufactured in Canada and use only components and technology developed in North America,” said Rosentreter, explaining the company's commitment to information security. The first of these drones are already in the manufacturing stage of development. Timing is everything Transport Canada's June 2019 release of its remotely piloted aircraft systems (RPAS) regulations were serendipitous for the company and provided a road map for the integration of drones into the national airspace system. Pegasus Imagery has identified benchmarks and critical areas of interest that it needs to be able to fly beyond visual line of sight (BLVOS) in Canada. This ability is required for the pilots to collect data at scale. Pegasus holds a unique special flight operations certificate from Transport Canada authorizing operations up to 2,000 ft in all restricted airspace across Canada. Pegasus is also working with Transport Canada and early adopters on BVLOS trials in uncontrolled airspace starting in 2020. Since relocating to the Edmonton International Airport last March, the airport authority has become a close partner, helping the company to transition from aircraft development into the trials and beyond. Partnering with commercial aviation The Helicopter Association of Canada expects to see a net loss of 7,000 pilots by 2035. With personnel shortages looming, drones can free up pilots to work where they are most needed. “We are not here to replace jobs; we are here to make jobs more efficient for the people doing them. It's about playing to everyone's strengths. We excel at persistent monitoring and information sharing that enables manned aviation to fly more. “For example, in a wildfire situation, drones can gather data 24 hours a day from above the fire and not put pilots in danger. Very few aircraft fly at night near a wildfire, and the night shift is a natural place to start filling that information void. We're going to see this transition to daytime use as well. By flying a few thousand feet higher than the helicopters, bird dogs, and waterbombers, the real-time information provided allows those pilots to respond where they are needed most,” explained Rosentreter. Drones are also well suited to detecting fires over large areas of land within minutes. “When you look at the root cause of wildfires, you see that from the time a fire starts to when it is detected can be anywhere from minutes to days,” Rosentreter continued. Alberta has 127 lookout towers for fire detection, it is a massive infrastructure and personnel investment. Officers look for smoke on the horizon, but often by the time a fire is big enough to do that, it is too large to be put out by a single helicopter team. The length of time between fire detection and the point where it can no longer be actively engaged and suppressed can be very short. “Unmanned aircraft can operate 24-7 at scale to detect a fire in minutes allowing for the immediate deployment of the best resources,” he further explained. Additionally, after a fire, drones are also able to offer 3D mapping of the affected areas to assist with recovery methods. Rosentreter is passionate about the service Pegasus Imagery is providing. “First responders have the mission of keeping our communities, environment and economy safe here at home. We can provide the tools to assist them. Their mission is really our mission.” https://www.skiesmag.com/news/pegasus-imagery-imagining-a-smarter-future
