    Raytheon Unveils Platoon-Sized Infantry Combat Simulator

    By Matthew Cox Defense contractor Raytheon has just unveiled a new virtual training simulator designed to immerse full platoons of soldiers at a time into realistic battlefield settings, where they can shoot enemy targets with individual weapons and even call in close-air support. Raytheon began showing off its new Synthetic Training Environment Soldier Virtual Trainer at the Interservice/ Industry Training, Simulation and Education Conference (I/ITSEC) in Orlando, Florida this week. The prototype system is Raytheon's attempt to satisfy the U.S. Army's need to create a synthetic training environment that dramatically increases the level of realism in training. "They need a way to get soldiers into the same virtual environments that they have had for tanks and helicopters for decades," Harry Buhl, lead investigator for synthetic training at Raytheon, told Military.com. "When you do that in an immersive, synthetic environment, you can go beyond the [live-fire] range -- you can put people soldiers into urban scenarios or into combat-type scenarios ... so you can stress them at a higher level and gain higher levels of proficiency." The Army recently told industry officials that it will begin seeking prototype solutions early next year designed to develop similar types of simulator training technologies. "We intend to compete for that opportunity," Buhl said. Currently, Raytheon is demonstrating its new soldier virtual trainer to simulate an observation post for two soldiers. But it can be configured for much larger units, Buhl said. "We can support up to a platoon ... that is something that the Army hasn't asked for. But the technology path that we have chosen allows us to actually do this for a platoon-sized unit over a large area. So we have the capability to do squad training or situational training exercises which we believe will be the next step as the Army goes down this path," Buhl said. The new trainer uses very high-quality graphics, similar to high-end games and relies on virtual-reality headsets and instrumented weapons, he said. "You can pick up a weapon, and the weapon is in that virtual environment," Buhl said. "When you put your cheek to the stock of that weapon, you have that same sight [picture] as you would in real life, but you are in a virtual environment." The trainer relies on commercially available tracking sensors, roughly two-inch cubes, that are spread out across any area, Buhl said. "The software package that we put behind them will link them together and make them smart enough to understand where you are in the environment so that you can be realistically replicated in the synthetic environment," Buhl said. "As you ... take a knee, go to the prone, you are doing the same things in that synthetic environment. "If you were training on a basketball court, you could put these things up in the rafters of the basketball court and just leave them there." Eventually, the sensor technology will be built into the headsets, so there will be no need for tracking sensors, Buhl added. One of the features the Army is looking for is the ability for soldiers to train for calling in artillery or close-air support, Buhl said, describing how Raytheon's simulator shows realistic training distances. "You are ... on a hilltop looking down the valley, you've got some threat vehicles few miles away," he said. "You have [Air Force] A-10s circling overhead; they come down and you control them and call in their attack, so that you can apply close-air support directly on those targets." The simulator also allows soldiers to engage enemy targets with individual weapons at realistic ranges, another feature on the Army's wish list, Buhl said. If soldiers are using a rifle with an effective range out to 500 meters "you can engage targets out to 500 meters," he said. The trainer will also allow units to train for scenarios involving checkpoints that could call for the need to escalate from using non-lethal devices to lethal force, Buhl said. The Army is now developing the Integrated Visual Augmentation System (IVAS), a Microsoft-based headset that uses augmented reality to equip soldiers with a heads-up display allowing them to sight their weapon and view key tactical data. Scheduled to be ready for fielding in fiscal 2021, IVAS will also allow soldiers to train in synthetic training scenarios such as mission rehearsals before going on a live operation. Buhl said Raytheon used virtual-reality headsets because it "provides an immediate capability" the Army could take advantage of, but the system will be adaptable to work with augmented-reality headsets used with IVAS. "All of this is ... able to be packed up in a Pelican case and taken anywhere in the world," Buhl said. "It's also cloud-enabled, so if you did want to link into a networked training exercise with soldiers in another location, with tanks or helicopters that are in synthetic simulators, you could do all of that." https://www.military.com/daily-news/2019/12/03/raytheon-unveils-platoon-sized-infantry-combat-simulator.html

    Australia’s C-130J Super Hercules airlifters to get SATCOM upgrade

    By: Mike Yeo Correction: The fuel tanks fitted on the C-130Js are new and not repurposed from the older "H" models, as originally described by the Royal Australian Air Force. MELBOURNE, Australia — Australia is undertaking a series of upgrades to the Lockheed Martin C-130J Super Hercules airlifter, improving connectivity, fuel payload and surveillance capabilities with the addition of new equipment. Working together with industry, the Royal Australian Air Force, or RAAF, has installed a wideband satellite communications system and is planning on fitting Litening pods onto one of its C-130J used as a capability demonstrator aircraft. RAAF is fitting external fuel tanks on its C-130J fleet. Group Capt. Tony Bull, director of capability development and transition at the RAAF's Air Mobility Group, told Defense News at the ongoing Avalon Airshow that these modifications are part of the RAAF's Plan Jericho umbrella, which seeks to transform the service into an integrated and networked 5th-generation Air Force. The SATCOM suite features Honeywell's JetWave Ka-band satellite communications hardware and Inmarsat's Global Xpress satellite network. Since it was fitted onto the Jerich Demonstator C-130J in 2017, the suite has successfully demonstrated its ability to use a number of secure military applications that previous technology couldn't enable due to bandwidth restrictions, including live video streaming and encrypted file transfer. According to Bull, the SATCOM system allows personnel on board to be linked with command elements and forces elsewhere, improving their situational awareness even while in transit and allowing missions to be replanned, to assess the battlefield environment. He said that the SATCOM trials have now proven the concept, and the program has since transitioned into a RAAF minor project with the intention being to eventually fit all of the RAAF's 12 C-130Js with the SATCOM capability. This SATCOM capability has not gone unnoticed by the U.S. Air Force, with personnel from Yokota Airbase in Japan, who also operate the C-130J, saying they were impressed by the capability when they encountered it during their interactions with the RAAF. Bull also added that the plan to fit the Rafael/Northrop-Grumman AN/AAQ-28 Litening pod to the C-130J demonstrator, which was revealed recently, will allow the C-130J to conduct surveillance of a target area. He gave the example of its potential use during disaster relief operation, with the pod being able to provide vision of a target area. Forces could then assess needs from either on board the aircraft, or use the SATCOM to stream video to a command or headquarters element elsewhere, and make decisions based on the situational awareness provided. These capability improvements are meant to enhance the C-130J's primary role as an airlifter, however, and the RAAF has no intention to expand the C-130J's missions into that of a surveillance aircraft, for example. Australia has a number of surplus Litening pods as it starts the withdrawal of its F/A-18A/B Hornet multirole fighters over the next few years. The pods were acquired by Australia in 2008 as part of its program to upgrade its fleet of Hornets. Bull also touched on the installation of external fuel tanks onto the C-130Js, with five sets of external fuel tanks now available for use on the C-130Js. In addition to extending the range of the airlifters, the tanks could also be utilized during the forward arming and refuelling point or FARP operations to offload fuel without having to sacrifice the C-130J's own internal fuel capacity or carry it in its main cabin. This frees up space in the aircraft to carry other cargo. These modifications to the RAAF's C-130Js are being conducted in conjunction with Airbus, which is also responsible for providing through life support for Australia's C-130J fleet. The company, which has supported the fleet since 2009, signed a rolling contract in late 2018 to continue the work for an additional six years through to 2024. https://www.defensenews.com/digital-show-dailies/avalon/2019/02/26/australias-c-130j-super-hercules-airlifters-to-get-satcom-upgrade/
