  Lockheed Martin-Built AEHF-5 Protected Communications Satellite Now in Transfer Orbit

  The Lockheed Martin (NYSE:LMT)-built AEHF-5 satellite is now responding to the squadron's commands as planned. The squadron began "flying" the satellite shortly after it separated from its United Launch Alliance Atlas V 551 rocket approximately 5 hours and 40 minutes after the rocket's successful 6:13 a.m. ET liftoff. AEHF-5 complete a geostationary ring of five satellites delivering global coverage for survivable, highly secure and protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms. Besides U.S. forces, AEHF also serves international partners including Canada, the Netherlands and the United Kingdom. "This fifth satellite adds an additional layer of flexibility for critical strategic and tactical protected communications serving the warfighter. This added resilience to the existing constellation will help ensure warfighters can connect globally to communicate and transmit data at all times," said Mike Cacheiro, vice president for Protected Communications at Lockheed Martin Space. "In the weeks ahead, AEHF-5 will move towards its operational orbit, deploy all of its solar arrays and antennas, and turn on its powerful communications payload for a rigorous testing phase prior to hand over to the Air Force." AEHF-5, with its advanced Extended Data Rate (XDR) waveform technology, adds to the constellation's high-bandwidth network. One AEHF satellite provides greater total capacity than the entire legacy five-satellite Milstar communications constellation. "Individual data rates increase five-fold compared to Milstar, permitting transmission of tactical military communications, such as real-time video, battlefield maps and targeting data," said Cacheiro. "AEHF affords national leaders anti-jam, always-on connectivity during all levels of conflict and enables both strategic and tactical users to communicate globally across a high-speed network that delivers protected communications in any environment." Lockheed Martin designed, processed and manufactured all five on-orbit AEHF satellites at its advanced satellite manufacturing facility in Sunnyvale, California. The next AEHF satellite, AEHF-6, is currently in full production in Silicon Valley and is expected to launch in 2020. The AEHF team includes the U.S. Air Force Military Satellite Communications Systems Directorate at the Space and Missile Systems Center, Los Angeles Air Force Base, Calif. Lockheed Martin Space, Sunnyvale, Calif., is the AEHF prime contractor, space and ground segments provider as well as system integrator, with Northrop Grumman Aerospace Systems, Redondo Beach, Calif., as the payload provider.

  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/
