  Marines want a better way do force-on-force tactical shooting training

  After decades of using laser-type devices for shooting simulations and force-on-force tactical warfighting, the Marine Corps is asking for a new way to do fake shooting. A recent request for information is asking the commercial industry to bring ideas to the Corps that would help it make simulated shooting more realistic for up to a battalion-size force and improve current systems. Some versions of those systems have been in operation since Nintendo's Duck Hunt video game was considered high-tech shooting and laser tag advertisements dominated Saturday morning cartoons. This won't hit every Marine Corps installation but many will have it. Based on the RFI, the systems would be employed “to provide turnkey instrumented exercises with After Action Review (AAR) at 29 Palms, Camp Lejeune, Camp Pendleton, MCB Hawaii, MCB Okinawa or MCB Quantico within 3 weeks of notice, as well as support additional exercises upon request at Camp Fuji, Japan, Marine Corps Mountain Warfare Center, MCB Yuma, and specified reserve locations.” And the Marines are not doing this alone. They will be leveraging the Army's Live Training Engagement Component software. That's a tactical training framework so that simulations can be on the same standards and work jointly with other services and potentially foreign partners. One of the key cross functional teams that the Army formed last year included simulated training environment work. The goal is to incorporate better simulations for training at all levels, beginning in the design and procurement of future weapons and other equipment systems. The Corps wants a system that would be able to simulate all weapons and vehicles typically seen in a battalion, which would include at least: M4/M16; M9 or sidearm, the M27 Infantry Automatic Weapon; hand grenades; rocket propelled grenades; Light Anti-Tank Weapon; 60mm mortars; 81mm mortars; Claymore antipersonnel mine; Mk-19 grenade launcher; Russian machine gun; AK-47 variants; M41 TOW; Javelin missile and the Carl Gustaf recoilless rifle. It would distinguish between a hit, wound or miss and record information for after-action reviews. Marine Corps Times first reported news of this initiative last year following an interview with then-program manager for Training Systems at Marine Corps Systems Command, Col. Walt Yates. At the time, Yates described some of the shortfalls of using lasers when gauging accuracy and real-world effects. “A laser is at the speed of light, and the bullet is not,” he said. Yates previously said that though the current shooting systems are a generational change from old MILES, or multiple integrated laser engagement system, lasers have fundamental flaws for realistic battle scenarios. For example, laser-based systems shoot line-of-sight, making arcing weapons such as mortars and grenade launchers more difficult to simulate. Lasers can also be deflected by light concealment such as tree leaves and thin walls. And the number of troops and shooting ranges will change with new systems. The first generation ITESS accommodated 120 Marines and opposition forces, the second generation expanded to 1,500 with a communication radius of 5 to 8 km. The third seeks to track up to 2,500 Marines, making it capable of battalion on battalion exercises envisioned by the commandant, Yates said in the November interview. A new simulator must act more like a real bullet, requiring Marines to lead their moving targets, fire rifles on semi, burst and fully automatic modes and ensure the bullet travels in the realistic path, which is not perfectly line of sight, he said. https://www.marinecorpstimes.com/news/your-marine-corps/2018/06/04/marines-want-a-better-way-do-force-on-force-tactical-shooting-training/

  À Saclay, la DGA simule l’altitude pour tester les moteurs en conditions extrêmes

  L'Usine Nouvelle consacre un article au Centre d'Essais des Propulseurs du Ministère des Armées, situé sur le plateau de Saclay (Essonne), qui dispose de moyens uniques en Europe pour reproduire au sol les conditions de vols extrêmes subies par les aéronefs. Le centre technique utilise l'eau, venue des étangs voisins de Versailles, qui, amenée aux températures et aux pressions voulues, permet de récréer les flux d'air et les conditions atmosphériques de vol dans de grands caissons capables d'accueillir des moteurs. Les cinq caissons atmosphériques du centre permettent de reproduire des conditions de vol extrêmes, que ce soit en termes d'altitude (jusqu'à 20 000 mètres), de vitesse (jusqu'à Mach 3) et de température (de - 70 à + 250 °C). « Par rapport à un vol réel, nous maîtrisons mieux les tests et nous pouvons plus facilement étudier les paramètres qui nous intéressent », explique Marie-José Martinez, la directrice du site. Au-delà des programmes d'armement, le centre propose également des prestations aux grands motoristes mondiaux, tels que Safran ou Rolls-Royce. L'avion de combat SCAF pourrait aussi en bénéficier.

  What could a military do with this flying saucer?

  By: Kelsey D. Atherton This may be a flying saucer, but don't call it a UFO. Carefully named, the All DIrections Flying Object, or ADIFO, is instead a saucer-like contraption, a flying prototype built at exploring the aerodynamic potential of an alien craft. It is, at its core, an omnidirectional flying wing built around a quadcopter with jets attached. Its designers see a future for the airframe as an unmanned combat aerial vehicle. In a video posted July 1, a narrator discusses the design process and aerodynamics of the craft. Like many VTOL tools built on a quadcopter frame, ducted fans provide initial lift and mobility at low altitudes and low speeds. The addition of vectored jets on the rear of the craft, combined with four vertical vents and four side-facing vents, promising greater maneuverability at high speeds. The ADIFO is the invention of Romanian engineer Razan Sabie in conjunction with Iosif Taposu, a scientist with a long career in aerospace research for the Romanian government. “The aerodynamics behind this aircraft is the result of more than two decades of work and is very well reasoned in hundreds of pages and confirmed by computer simulations and wind tunnel tests,” Sabie told Vice, in the pair's first American interview. That story explores both the specific nature of the ADIFO, and the long and mostly failed history of flying saucer design. Like many other ideas for the first decades of aviation, the possibility of operating the craft without a human on board opens up greater potential in what an airframe can actually do. Human pilots are subject to the limitations of a body and perception, and a flying disk changing directions suddenly at high speed is not the ideal place for a human to be. Uncrewed craft can take on novel forms, and execute turns and twists beyond those human limits. While maneuverability is likely the primary selling point for a future role as combat aircraft, the smooth and fin-free form could easily have stealth characteristics built in, and could be further adapted by a dedicated team to fully realizing that stealth flight. What might a military planner or designer do with such a machine? The proof-of-concept offers little in the way of information about storage space or sensors. With wide enough lenses, a handful of cameras could match the circular symmetry of the vehicle and provide and omnidirectional surveillance presence. The high speeds and potentially low radar profile suggest a role akin to earlier, Cold War spy planes, taking specific pictures in contested space and returning before anti-air systems can act. And as with any aircraft, the potential is likely there for it to release an explosive payload, taking the flying saucer from an extraterrestrial fear to a terrestrial threat. ADIFO might not be the future of anything. The project's home page says the team is still attracting partners, and aviation history is littered with proofs-of-concept that failed to materialize in a meaningful way. Yet there is something to the idea of a flying saucer working the moment it no longer has to transport a human. It is an old aviation frontier that likely warrants further exploration. https://www.c4isrnet.com/unmanned/2019/08/12/what-might-a-military-want-with-a-romanian-flying-saucer/
