    Navy practices with key anti-mine asset: dolphins

    By: Andrew C. Jarocki WASHINGTON ― When it comes to minesweeping at the 2018 Rim of the Pacific exercises, the top sonar for the job isn't located on any of the 46 ships and five subs sailing in the maneuvers. Instead, the Navy relies on dolphins. The highly-trained creatures “search for and mark the location of undersea mines” according to a description by the U.S. Navy Marine Mammal Program, which also deploys sea lions to recover suspicious objects at deep depths. The dolphins “possess the most sophisticated sonar known to science,” allowing them to find mines in any depth or light when mechanical equipment is often less reliable, the Navy says. That skill proves especially useful in crowded coastal waters or on murky sea floors. Navy RIMPAC footage released to the public shows dolphins, overseen by human trainers, finding practice mines and placing markers near them. Their reward? A steady stream of fish treats. https://www.navytimes.com/news/2018/07/27/navy-practices-with-key-anti-mine-asset-dolphins/

    Russia, U.S. Are In a Military Exoskeleton Race

    By Patrick Tucker A look at the Iron Man-like dreams and power-starved realities of dueling technology programs. The Russian suit, Ratnik-3, is an imposing web of hexagonal armor plates, black webbing, and small joint motors called actuators. Oleg Faustov, an engineer working with weapons maker TsNiiTochMash, told Russian media outlet TASS this week that the government had already tested a prototype. “It really enhances a serviceman's physical abilities. For example, the tester was able to shoot from a machine-gun only with one hand and accurately hit targets,” he said at Russia's recent Army-2018 weapons show. As part of the Army-2018 publicity push, the makers of the suit also made vague and unverifiable claims that it had seen actual combat, according to Sam Bendett, an associate research analyst at CNA and a fellow in Russia studies at the American Foreign Policy Council. “It was interesting that the Russian announcement during Army-2018 stated that the exoskeleton was ‘tested in combat,' though without any specific details. It's likely that it was tried in Syria, though the press and media did not cover that development,” he said. While the statement came from the suit's maker, Bendett said he assumes the claim “had to be approved by the state given the combat claims.” The suit is supposed be officially released in 2025. In addition to an almost comically Black Manta-esque helmet, the Ratnik-3 features “40 life-saving elements,” Russian media says. In many ways, it resembles some of the more recent concept images of the TALOS suit that U.S. Special Operations Forces Command, or SOCOM, is attempting to develop. In both, all those bells and whistles seem to be an obstacle to the suit reaching full utility. Both the Ratnik-3 and TALOS efforts seem constrained by available power. “There are issues with the battery and energy sources for this exoskeleton, as Russia—along with other nations working on this—are trying to create a compact energy source that would allow the soldiers to act independent of any stationary or vehicle-borne sources of energy,” Bendett said. Even Russian media have noted the suit's power constraints, noting that a battery life of less than four hours isn't super practical for a day of marching. A forthcoming series of reports from the Center for New American Security, or CNA, takes a deep dive into the issue of soldier augmentation and reaches a similar conclusion. “The current state of technology still does not have sufficient power to manage the intense load-carrying capacity that the SOCOM TALOS suit concept requires...and development is needed before full-body exoskeletons will be feasible for infantry combat away from a reliable power source. Still, these advances represent a major step forward in the necessary technology for dismounted soldier exoskeletons,” notes the report. While size and power constraints are hindering the realization of militaries' most ambitious Iron Man dreams, more modest exoskeleton suits are moving closer to real-world use. The U.S.Army is experimenting with two exoskeleton designs at the Natick Soldier Systems Center in Massachusetts. These won't protect soldiers from enemy fire but they will help soldiers carry more stuff for longer. And they'll likely be on the battlefield far sooner. “Exoskeletons with more modest goals, such as lower-body exoskeletons that are designed simply to increase mobility, reduce energy expenditure, and reduce musculoskeletal injuries, may show more promise in the near-term,” according to the CNAS report. The larger of the two is the ONYX from Lockheed Martin. At a Pentagon event in May, Defense One caught up with Keith Maxwell, a product manager from Lockheed Martin, who described the results of initial tests in November, 2016. “We did an evaluation with some soldiers. They were doing 185-pound squats with the barbell. At the beginning of the day, fresh, Johnny comes in and does 26 reps at 185, puts it down. hat's as many as he can do. We put this on; over the course of the day, he's doing casualty evacuations, carrying people up five flights of stairs and down, going through subterranean tunnels. At the end of the day, we put him back in the gym, ask him, ‘How many squats can you do?' He knocks out 72.” Full article: https://www.nextgov.com/emerging-tech/2018/09/russia-us-are-military-exoskeleton-race/150956/

    Here’s what we know about the Space Force’s acquisitions plan

    By: Nathan Strout The newly establish United States Space Force is expected to deliver a report outlining its acquisition plans to Congress by the end of the month, but in a series of hearings this week lawmakers got a first look at how Space Force leadership is approaching the problem. One of the primary issues the Space Force faces in organizing its acquisitions is the relationship between the three main space acquisitions entities: the Space and Missile Systems Center, the Space Development Agency and the Space Rapid Capabilities Office. SMC is the largest of the three and has been responsible for most Air Force space acquisitions, while the other two organizations were established in the last two years to address specific capability gaps. Legislation passed by Congress called for creation of a position in fiscal year 2022 to oversee the three organizations, but it did little to clarify their roles or relationships, leading to some concerns of redundancy. The Space Force seems set to follow that model. Space Force Vice Commander Lt. Gen. David Thompson reportedly stated that the three entities would be put under the jurisdiction of a new Space Systems Command, although they will continue to be three separate organizations. When asked about this proposal at a Senate Armed Services Committee hearing March 3, Air Force Chief of Staff Gen. David Goldfein assured lawmakers the Space RCO would remain independent, as Congress intended. “While there will be a lot of discussions about (administration) and bureaucracy, our job is to deliver capability and to deliver it fast—at the speed of relevance—because that's exactly what the threat companies are doing,” said Goldfein. “Space RCO (...) needs to stay independent, and it needs to be able to move fast without a lot of lines and boxes that all get a chance to vote on what they're doing.” In a separate hearing before the House Appropriations Committee Subcommittee on Defense March 4, Thompson emphasized that leaders were already working to ensure the three organizations were on the same page. “We have already begun the process even before the Space Force was established (...) of working between the SMC, the SDA, the Space RCO (...) and others to ensure that their acquisition processes are synchronized, complementary and not duplicative in many senses,” Thompson said. Thompson also briefly outlined the expected roles of the three organizations. SMC will continue to develop and acquire those unique capabilities the military has depended on for decades, including protected communications, missile warning and GPS, he explained, while the Space RCO, which was established two years ago, will continue to rapidly develop and prototype new capabilities. Finally, the SDA's focus will be on leveraging commercial technologies, especially when it comes to utilizing proliferated constellations in low earth orbit. “Consolidating them under a specific acquisition organization will further integrate their activities and ensure they are not duplicative, but make sure they create one, single space architecture,” said Thompson. “Right now our focus is in driving an agile and rapid response for all of them as they continue to develop space capabilities for the mission.” More details on the Space Force's plans will be delivered in a report to Congress by the end of the month. Space Force Chief of Space Operations Gen. John Raymond said he expects to see a draft of the Space Force's acquisitions plan next week. https://www.c4isrnet.com/battlefield-tech/space/2020/03/04/details-emerge-on-space-forces-acquisitions-plans/
