    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/

    Destroyers Maxed Out, Navy Looks To New Hulls: Power For Radars & Lasers

    By SYDNEY J. FREEDBERG JR. ARLINGTON: The Navy has crammed as much electronics as it can into its new DDG-51 Flight III destroyers now beginning construction, Rear Adm. William Galinis said this morning. That drives the service towards a new Large Surface Combatant that can comfortably accommodate the same high-powered radars, as well as future weapons such as lasers, on either a modified DDG-51 hull or an entirely new design. “It's going to be more of an evolutionary approach as we migrate from the DDG-51 Flight IIIs to the Large Surface Combatant,” said Galinis, the Navy's Program Executive Officer for Ships. (LSC evolved from the Future Surface Combatant concept and will serve along a new frigate and unmanned surface vessels). “(We) start with a DDG-51 flight III combat system and we build off of that, probably bringing in a new HME (Hull, Mechanical, & Engineering) infrastructure, a new power architecture, to support that system as it then evolves going forward.” “Before the end of the year, we'll start reaching out to industry to start sharing some of the thoughts we have and where we think we're going,” Galinis told a Navy League breakfast audience. “We'll bring industry into this at the right point, but we're still kind of working a lot of the technology pieces and what the requirements are right now.” Evolution, Not Revolution This evolutionary approach is similar to how the current Aegis combat system entered service on the CG-47 Ticonderoga cruisers in 1983 but came into its own on the DDG-51 Arleigh Burke destroyers. (Despite the difference in names, the two classes are virtually the same size). The DDG-51 is now the single most common type in the fleet, a vital part of the hoped-for 355-ship Navy, with some ships expected to serve into the 2070s: There are now 64 Arleigh Burkes of various sub-types in service; nine of the latest Flight IIA variant are in various stages of construction; and work is beginning on the new Flight IIIs in Mississippi (Huntington Ingalls Industries) and Maine (General Dynamics-owned Bath Iron Works). The Navy is doubling down on long-standing programs to keep its older warships up to date and on par with the newest versions. But the current destroyers just won't be able to keep up with the Flight III, which will have a slightly modified hull and higher-voltage electricity to accommodate Raytheon's massive new Air & Missile Defense Radar. A stripped down version of the AMDR, the Enterprise Air Search Radar (EASR, also by Raytheon) is already going on amphibious ships and might just fit on older Burkes as well, however. But it's tight. On the Flight III, even with the hull modifications, “you kind of get to the naval architectural limits of the DDG-51 hullform,” Galinis told a Navy League breakfast this morning. “That's going to bring a lot of incredible capabilities to the fleet but there's also a fair amount of technical risk.” The Navy is laboring mightily to reduce that risk on Flight III with simulations and land-based testing, including a full prototype of the new power plant being built in Philadelphia. But it's clear the combat system is out of room to grow within the limits of the current hull. So how different does the next ship need to be? “How much more combat capability can we squeeze into the current hullform?” Galinis said. “Do we use the DDG-51 hullform and maybe expand that? Do we build a new hullform?” “We're looking at all the options, Sydney,” he said when reporters clustered around him after his talk. “(It's in) very, very early stages... to say it'll be one system over another or one power architecture over another, it's way too early.” “We're still working through what that power architecture looks like,” Galinis told the breakfast. “Do we stay with a more traditional (gas-driven) system... or do we really make that transition to an integrated electric plant — and at some point, probably, bring in energy storage magazines...to support directed energy weapons and things like that?” The admiral's referring here to anti-missile lasers, railguns, and other high-tech but electricity-hungry systems. Having field-tested a rather jury-rigged 30 kilowatt laseron the converted amphibious ship Ponce, the Navy's next step is a more permanent, properly integrated installation next year on an amphibious ship, LPD-27 Portland. (Subsequent LPDs won't have the laser under current plans). But Portland is part of the relatively roomy LPD-17 San Antonio class, which has plenty of space, weight capacity, power, and cooling capacity (SWAP-C) available, in large part because the Navy never installed a planned 16 Vertical Launch System (VLS) tubes in the bow. By contrast, while the Navy's studying how to fit a laser on the Arleigh Burkes, the space and electricity available are much tighter. The DDG-1000 Digression The larger DDG-1000 Zumwalt class does have integrated electric drive that's performing well in sea trials, Galinis said. (That said, the brand-new DDG-1001, Michael Monsoor, has had glitches with the harmonic filter that manages the power and, more recently, with its turbine engine blades). “We've learned a lot from DDG-1000” that the Navy's now applying both to its highest priority program, the Columbia-class nuclear missile submarine, and potentially to the future Large Surface Combatant as well. In other ways, DDG-1000 is a dead end, too large and expensive for the Navy to afford in quantity. The Navy truncated the class to just three ships and restarted Arleigh Burke production, which it had halted on the assumption the Zumwalts would be built in bulk. Today, the Zumwalt‘s very mission is in doubt. The ship was designed around a 155 mm gun with revolutionary rocket-boosted shells, but ammunition technology hasn't reached the ranges the Navy wanted for the original mission of bombarding targets ashore. With the resurgence of the Russian fleet and the rise of China's, the Navy now wants to turn the DDG-1000s into ship-killers, which requires even longer ranges because modern naval battle is a duel of missiles. The gun's place in ship-to-ship combat is “probably not a significant role, at least not at the ranges we're interested in,” Galinis told reporters. While the Navy could invest in long-range cannon ammunition, he said, it's paused work on several potential shells it test-fired last summer, awaiting the final mission review. If the Zumwalts do move to the anti-ship mission, which Galinis said they would be well suited for with minor modifications, their guns will be less relevant than their 80 Advanced VLS missile tubes or future weapons such as railguns drawing on their prodigious electric power. That power plant might evolve into the electric heart of the future Large Surface Combatant — or it might not. “We're going to have the requirements discussion with Navy leadership and then we're going to want to engage industry as we start thinking about what options might be available,” Galinis said. “Frankly industry's probably best suited to try to help us with the technology piece, especially if we start thinking (that) we want an innovative electric plant.....We'd go to probably the big power electronics/power system vendors, who really work in that field and have the best information on where technology's going.” https://breakingdefense.com/2018/07/destroyers-maxed-out-navy-looks-to-new-hulls-power-for-radars-lasers/
