  DARPA Wants to Make Underground Maps on the Fly

  The agency is challenging teams to build systems that chart caves, tunnels and underground urban infrastructure. Finding your way through caves and tunnels is both difficult and extremely dangerous, but the Pentagon's research office wants to build technology that can navigate underground environments while humans stay on the surface. The Defense Advanced Research Projects Agency is finalizing teams for its Subterranean Challenge, or SubT, a three-year competition to build systems that can rapidly map and search often treacherous underground areas. The agency on Thursday awarded a $4.5 million contract to Virginia-based iRobot Defense Holdings and a $750,000 contract to Michigan Technological University to participate in the challenge. A third team, Scientific Systems Company Inc., joined the program on July 31 with a $492,000 contract. “Even under ideal conditions, these complex environments present significant challenges for subterranean situational awareness,” DARPA wrote in the program announcement. “However, in time-sensitive scenarios, whether in active combat operations or disaster response settings, warfighters and first responders alike are faced with a range of increased technical challenges, including difficult and dynamic terrains ... severe communication constraints, and expansive areas of operation.” Full Article: https://www.defenseone.com/technology/2018/08/darpa-wants-make-underground-maps-fly/150554/

  Army Selects BAE Systems Jammer For Future Active Protection Testing On Bradleys

  By Matthew Beinart The Army has selected a BAE Systems' electronic countermeasure capability for future evaluations after a successful demonstration at a soft-kill “rodeo” last fall, with plans to evaluate the system on a Bradley fighting vehicle during a layered active protection... https://www.defensedaily.com/army-selects-bae-systems-jammer-future-active-protection-testing-bradleys

  US Navy upgrades more ships for the F-35 as the future of carriers remains in flux

  By: David B. Larter WASHINGTON — Former acting Navy Secretary Thomas Modly hadn't been out of the job more than a month before the Navy canceled an ongoing study he'd launched into the future of aircraft carriers — a review he optimistically termed “Future Carrier 2030.” Modly and his predecessor, Richard Spencer, had been excited by the prospect of fielding smaller, more risk-worthy carriers that could reduce the chance of China or Russia landing a major punch in a conflict simply by sinking or disabling a single ship, such as a Nimitz- or Ford-class aircraft carrier with thousands of sailors and tens of billions of dollars of hardware aboard. But very soon after Modly's spectacular departure, former acting Secretary James McPherson canceled the study until further notice. Still, as the effort to move to a smaller carrier seems frozen — as it has been for decades every time someone suggested it — the Navy is forging ahead with preparing its big-deck boats — the amphibious assault ships — for operating with the Marine Corp's F-35B. The Corps' F-35 fighter jet is a short-takeoff-and-vertical-landing variant. The Navy recently inked a $200 million contract with BAE Systems to upgrade the amphibious assault ship Boxer to be able to operate with the F-35 Joint Strike Fighter, the fifth landing helicopter assault ship to be so amended. “The USS Boxer [dry-dock availability] will complete a combination of maintenance, modernization, and repair of the following systems: Hull structure, propulsion, electrical plant, auxiliary systems, and communications and combat systems, as well as alterations to prepare the ship for operations with the F-35B Joint Strike Fighter (JSF),” according to a statement from Naval Sea Systems command. But the idea of smaller carriers is one the Navy has been flirting with more recently. Last fall, the Navy packed 13 F-35Bs on the amphibious assault ship America. Then-Navy Secretary Spencer later said the ship could hold up to 20. “I will tell you, we are augmenting the aircraft carrier with our ideas, such as this lightning carrier,” Spencer said at the Brookings Institution think tank. “Twenty F-35 Bravos on a large-deck amphib. My cost performance there is tremendous. Does it have the same punch? No, it doesn't, but it does have a very interesting sting to it.” The Boxer, which is an older class of big-deck amphib, could likely pack about 15 F-35Bs if it were dedicated for the purpose, according to Bryan Clark, a senior fellow at the Hudson Institute.
