  Ready, Fire, Aim: PACAF Chief Emphasizes Hypersonics

  Steve Trimble As the U.S. Defense Department accelerates hypersonic weapons fielding, the air force's top commander in the Pacific region emphasizes that the missile isn't the only technology required to realize an operational capability to strike targets at speeds faster than Mach 5. The air force plans to achieve an early operational capability in fiscal 2022 with the Lockheed Martin AGM-183A Air-launched Rapid Response Weapon, a maneuvering boost glide missile fired from the wing of an aircraft, such as a Boeing B-52. Such weapons are capable of hitting targets at ranges over 1,000 km within 10 min., but similarly new advances in intelligence-gathering and command and control infrastructure are required in order to make full use of them, said Gen. Charles Brown, commander of Pacific Air Forces. “In the time of flight, eight to 10 minutes, I've got to have pretty good intel that the target is still going to be there, particularly if it's a mobile target,” Brown said. “Those are things I'm thinking about. It's nice to have this weapon, but I've got to have the whole thing.” The Defense Department also is working on other long-range-missile technologies. In August, Russia and the U.S. governments withdrew from the 32-year-old Intermediate-Range Nuclear Forces Treaty, allowing both countries to follow China's lead in fielding ground-launched ballistic and cruise missiles with a range of between 500 km and 5,000 km. Since August, the DOD has demonstrated a rudimentary ground-launched cruise missile and ballistic missile in flight, but a fielding decision is still pending a policy decision by the Office of the Secretary of Defense (OSD). Brown could offer no update on the status of the policy decision. “That may be a logical conclusion, but I'd refer you to OSD on where their approach is and where the department might land as far as where we're going in the future,” Brown said. https://aviationweek.com/shownews/singapore-airshow/ready-fire-aim-pacaf-chief-emphasizes-hypersonics

  What’s so sweet about sugar cube-sized robots?

  By: Kelsey D. Atherton If there is anything the future is lacking, it's robots the size of Chiclets. Draper, working under a grant from the Defense Advanced Research Projects Agency, is creating centimeter-sized robots, for future use in rescue work. The project is named “SHort-Range Independent Microrobotic Platforms,” or “SHRIMP” for short. And short is the nature of the game. SHRIMP is based on the 4 cm long, 1.5 g Harvard Ambulatory MicroRobot (HAMR), and wants to shrink it down to a single cubic centimeter. That will require microelectromechanical systems, 3D printing, piezoelectric actuators and, this is crucial, low-power sensors. Once all of that is in place, Draper claims the microbot will be able to jump, sense, navigate and control itself. The design will rely on feet inspired by living creatures to give it extra friction on rough and vertical terrain, and inertial measurement to detect where it is on the ground. “The microrobotic platform capabilities enabled by SHRIMP will provide the DoD with significantly more access and capability to operate in small spaces that are practically inaccessible to today's state-of-the-art robotic platforms,” declared DARPA in the proposer's day note. “Such capability will have impact in search and rescue, disaster relief, infrastructure inspection, and equipment maintenance, among other operations.” The exact “how” of what these robots will do in disaster relief, inspection, maintenance or other operations is yet to be determined, and will largely hinge on the sensors that can be fit to the platform. The most useful thing a small robot can do is get into a space and send information back to humans about that space, but that's hardly the only metric to evaluate the platform. As part of the SHRIMP program, DARPA will have the robot designs compete through a series of events modeled after the Olympics. These include high jump, long jump, weightlifting, shot put, tug of war, rock piling, steeplechase, biathlon, vertical ascent — all ways to find out what useful tasks tiny robots can do. There's a world of speculation between a dime-sized robot that can pile rocks and a useful military tool, but the fact that DARPA is invested in the technology as a platform suggests that, should the technology get there, the design will have some unexpected utility. In the meantime, DARPA's interest suggests there's good odds on a future market for sensors designed for dice-sized robots. https://www.c4isrnet.com/unmanned/robotics/2019/06/12/what-does-darpa-want-with-sugarcube-sized-robots/
