  US Army’s jumping to the next level in virtual training

  By: Jen Judson WASHINGTON — The U.S. Army has been building a virtual world in which to train soldiers for war, and it's expected to award contracts in June for reconfigurable virtual air and ground trainers and for a common synthetic environment that includes complex and real-life terrain. Maj. Gen. Maria Gervais, who leads the Synthetic Training Environment Cross-Functional Team, which is part of Army Futures Command, told reporters during a recent media roundtable that she's “encouraged” to see what her team accomplished since it formed roughly 18 months ago. While the service, at a time, led the charge when it came to developing virtual environments, it has clung to relics of the '80s and '90s — stove-piped training systems lacking in realism. As the Army shifts its focus to fighting in a multidomain environment, the service wants a new system that enables collective training across air, ground, sea, cyber and space with greater fidelity that can be used not only as a trainer but also as a mission-planning tool. Before the synthetic training environment, or STE, was prioritized through the establishment of Army Futures Command, it wasn't going to be ready until 2030, but Gervais shrunk that timeline through new approaches in development and acquisition by involving industry and soldiers in a collaborative and agile manner. What is the STE? Over the last 18 months, the components of the STE have taken shape and will consist of One World Terrain — which compiles realistic and accurate virtual maps of territory — training simulation software, a training management tool and virtual collective trainers. All of this will make up the soldier/squad virtual trainer and the reconfigurable virtual collective trainer. The idea is to be able to click on any place on a virtual globe and go there. Soldiers can then train virtually in an exact environment in which they can expect to operate in reality. Just a few years ago, building One World Terrain was painstaking, tedious and expensive, but through new technology applications, what used to take nine months to build can now take eight hours. The training simulation software will support training simultaneously across many locations and training platforms. The training management tool allows users to build training scenarios through simulation databases. The virtual trainers are being designed for dismounted, air and ground formations to train from a squad level through battalion, and ultimately at higher echelons. The trainer for the soldier and squad will support individual and collective task at the smallest formation. The reconfigurable virtual collective trainers, or RVCT, will represent Army and Marine Corps air and ground systems for training at the unit level and will be used for mission rehearsals at every echelon. Ready player one The Army plans to award contracts next month to build both an RVCT for aircraft and an RVCT for ground vehicles that are reconfigurable based on changes to platform inventories. The STE conducted an initial user assessment of what had been developed in March 2018, Gervais said. Since then, the Army has conducted more than 20 “touch points” with industry partners, which led to a user assessment in Orlando, Florida — where the STE cross-functional team is based — of One World Terrain, the training management tool as well as the training simulation software. Meanwhile, Gervais said, the team is in the middle of a user assessment of an RVCT—Air prototype at Fort Carson, Colorado, which began in April and is supported by soldiers from the 4th Infantry Division. The service completed its assessment of a ground simulation platform that went to Fort Riley, Kansas. Crew members for Abrams tanks, Bradley Fighting Vehicles and Stryker combat vehicles of the 1st Infantry Division supported that effort. One World Terrain is already in use and under evaluation by a Marine battalion as well as three divisions in the Army and Naval Special Warfare Command. It's also used at the National Training Center and by the 3rd and 7th special forces groups. All of the users are providing feedback, according to Gervais. A contract was awarded in September 2018 to build the squad advanced marksmanship trainer, which is a product of the Close Combat Lethality Task Force initiative to improve soldier lethality and survivability, and the capability is already fielded to the 10th Mountain Division at Fort Drum, New York. The new trainer takes what was a tethered system and — while it still uses projectors and screens — allows users to move around a base with more flexibility, which is more operationally realistic. Ultimately, the projectors and screens could be replaced by a headset, which is in keeping with the service's requirement to bring trainers to an operational unit in the field or at home station. This means the system must be easy to set up and transport. “We will continue to field that out to the Army the rest of this [fiscal year],” Gervais said. Taking it to the next level The Army plans to use the other transaction authority, or OTA, contracting mechanism to award contracts next month to move quicker and more agile than the standard and often lengthy acquisition process. The service previously used OTAs for STE development. “What the existing OTAs have done for us is they have actually allowed us to get a quick look from industry on where they were with the capabilities,” Col. Marcus Varnadore, the project manager for the STE CFT, said during the media roundtable. “It was very important for us right up front to identify where industry really was with respect to the technology, which allowed us to then make some decisions about what path to go forward with, and it also allowed us, with that first OTA, to kind of get an idea of how we needed to structure our follow-on OTAs,” he added. With the upcoming OTA contract awards, “we are kind of taking that and moving it to the next level using OTAs to bridge our gap here to get to the [initial operational capability] ... before we transition ultimately into a production [full-operational capability] environment,” said Brian Serra, the branch chief of Army Contracting Command—Orlando. “We are using the flexibility of OTAs,” he added, “to adjust as we go so we are not married to a 100-page specification.” That translates to the CFT taking a two-year process and shrinking it to six months max. The incremental process has also allowed the STE CFT to track industry's progress in this arena. Gervais noted that in some cases, companies might have overstated a specific technology's capabilities, and in turn the serve may need to bolster funding for internal science and technology efforts to improve that specific tech. Alternatively, the Army might notice it's been developing technology that is already well-developed in the commercial world. “I'm very confident and comfortable that our efforts to date are going to keep us on track to meet an initial operational capability of fourth-quarter FY21,” Gervais said. To reach initial operational capability, Gervais expects to field a battalion set of the RVCT—Air and RVCT—Ground — running on the common synthetic environment made up of One World Terrain, the training management tools and the training simulation software — to at least four installations. Over the next two years following initial operational capability, the Army will expand that fielding to include all installations where the capability is required in order to reach full operational capability by FY23. https://www.defensenews.com/land/2019/05/17/us-armys-jumping-to-next-level-in-virtual-training-world/

  US Air Force Could Struggle to Grow Its Fleet

  By Jon Harper The Air Force hopes to ramp up to 386 squadrons by 2030, but it could face challenges just to maintain its current size. The Congressional Budget Office estimates that the service would need significantly more funding annually than it has received in recent decades simply to replace aging airframes. The Air Force has about 5,600 aircraft, many of which are nearing the end of their service life, the nonpartisan research group noted in a recent report, “The Cost of Replacing Today's Air Force Fleet.” CBO estimates that replacing the planes in the current fleet one-for-one would cost an average of $15 billion a year (in fiscal year 2018 dollars) in the 2020s. That figure would rise to $23 billion in the 2030s and then drop back down to $15 billion in the 2040s. In comparison, appropriations for procuring new aircraft averaged about $12 billion per year between 1980 and 2017, and just $9 billion between 2010 and 2017, the report noted. “In CBO's projection, the procurement costs of new aircraft ... would rise to and remain at levels considerably above historical averages,” it said. Fred Bartels, a defense budget analyst at the Heritage Foundation's Davis Institute for National Security and Foreign Policy, said the Air Force is at risk of shrinking due to fiscal constraints, especially as other services such as the Navy seek to beef up their own force structures in the coming years. Even if the Air Force doesn't decline in size, modernization and force level increases could be delayed, he noted. “I can see the growth being slowed down a little bit here and there.” To maintain force structure, the Air Force might have to resort to life-extension efforts, he said. But that creates its own set of problems. “Your aircraft cost even more to operate because you're ... [holding] together a 50-year-old airplane,” Bartels said. “You're just creating different challenges all the time and you're increasing your [operation and maintenance] costs, which in turn decreases the availability of resources that you have to procure a new platform. So you end up in that vicious cycle.” Delaying modernization also puts the U.S. military at risk of falling behind the technological curve as it faces advanced adversaries. “You can't expect the same aircraft to still represent air superiority 30 years from when it's first released,” he said. The Air Force has been conducting an assessment to determine its force structure and modernization needs for the 2020s. Officials have concluded that the service would need 386 squadrons by 2030 to fulfill the requirements of the latest national defense strategy, which was released last year. It currently has 312 squadrons. The final results of the study are expected to be delivered to Congress in March. Air Force Vice Chief of Staff Gen. Stephen “Seve” Wilson said the service will present a strategy-driven assessment, not a “budget-driven strategy.” “The force that we think we need for the war fight that we think we need to be prepared for, is that 386 [squadrons],” he said during an interview with National Defense at the Reagan National Defense Forum in December. “We're going to continue to ... have that dialogue with both the House and the Senate.” http://www.nationaldefensemagazine.org/articles/2019/2/14/air-force-could-struggle-to-grow-its-fleet
