  More than meets the eye: Army selects next-gen camouflage system

  By: Kyle Rempfer The Army has finally selected a company to provide it with the next generation of ultra light-weight, general-purpose camouflage. The Army's Ultra-Light Camouflage Netting System, or ULCANS, will be an all-weather, state-of-the-art signature concealment system that provides multi-spectral protection for troops and equipment. The program aims to replace the legacy woodland and desert camouflage variants developed in the 1990s, and will be developed in light and dark woodland, snow and alpine, desert, and urban variants. The Army hopes ULCANS will better conceal the signatures of troops and equipment from high-end sensor threats on the battlefield. The contract to produce the next-generation camouflage was awarded to Fibrotex USA Inc., according to a company statement provided to Army Times. The contract is a 10-year, indefinite delivery and indefinite quantity award, with a total value of $480 million. Fibrotex is expected to begin full-rate production in early 2019, according to the company. ULCANS is the result of nearly two years of testing, trials and data collection conducted by the U.S. Army's Natick Soldier Systems Center in Massachusetts. Natick tested camouflage technologies from major global manufacturers against the Army's most advanced battlefield surveillance sensors. Many of the technologies underpinning ULCANS are based on developments by Fibrotex's Israel-based parent company over the last two decades, but have been specially modified for the U.S. Department of Defense. The Fibrotex system will provide multi-spectral camouflage, which conceals objects from detection across several portions of the electromagnetic spectrum at the same time. Traditional military camouflage simply hides an object in the visible spectrum, but the multi-spectral design obscures detection in the infrared, thermal and radar spectrum as well. “Today more than ever, military forces and opposition groups are using night vision sensors and thermal devices against our troops, but by using Fibrotex's camouflage, concealment and deception solutions, we make them undetectable again, allowing them to continue keeping us safe," said Eyal Malleron, CEO of Fibrotex USA. Fibrotex will also deliver the ULCANS material in reversible designs — allowing for the first time a different pattern and capability on each side, enabling soldiers, vehicles and systems to disappear into light or dark woodland, snow or alpine and desert or urban environments in any operational theater. “We have more than 50 years of experience, with thousands of hours in the field and a deep understanding of conventional and asymmetric warfare," Malleron said. "The U.S. Army tested our best camouflage solutions, and the camouflage repeatedly demonstrated the ability to defeat all sensors known to be operating in the battlefield and throughout the electromagnetic spectrum.” ULCANS will also be manufactured stateside, in a new state-of-the-art facility in McCreary County, Kentucky, creating hundreds of new skilled American jobs over the next decade, according to Fibrotex. “I firmly believe we have the best workforce in the country, and that their hard work and dedication has earned these new jobs, helping deliver a vital new military contract from McCreary County," Rep. Hal Rogers, R-Ky., said in a press statement. "I take great pride in knowing that our people are crafting these products to keep our warfighters and allies safe, giving them an edge on the battlefield.” The new facility is being established next to Outdoor Venture Corporation, which is a strategic partner to Fibrotex USA and already designs modular personnel tents and command post tents for the Army. https://www.armytimes.com/news/your-military/2018/11/07/more-than-meets-the-eye-army-selects-next-gen-camouflage-system

  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/
