  • Can a dragonfly teach a missile how to hunt?

    Can a dragonfly teach a missile how to hunt?

    By: Jen Judson WASHINGTON — A computational neuroscientist is studying whether a dragonfly's excellent hunting skills can be replicated in a missile's ability to maneuver and destroy targets midair with better precision. Dragonflies are vicious little creatures with a hit-to-kill track record of 95 percent, meaning only 5 percent of its prey escapes. Sandia National Laboratories' Frances Chance is building algorithms that simulate how a dragonfly processes information when intercepting prey, and she's testing them in a virtual environment. So far, the results are promising. The laboratories are federally funded and focus on national security missions through scientific and engineering research. The project is a yearlong, high-risk, high-gain effort that will wrap up in September, and it is funded by Sandia's Autonomy for Hypersonics Mission Campaign, Chance said. “I think what is really interesting about insects, in general, is they do something really fast and really well, but they are not particularly smart in the way you or I would think of ourselves as being smart,” Chance told Defense News in a recent interview. While insects may not be the right fit for studying cognitive capabilities to develop complex artificial intelligence, they are ideal for developing efficient computations for intercept capability. A dragonfly can react to a particular prey's maneuvers in 50 milliseconds, Chance explained. That amount of time accounts for information to cross three neurons in a dragonfly's brain. This indicates the dragonfly doesn't learn how to hunt, but rather the skill is inherent and part of its brain's hard-wiring. “The challenge then is: Is there anything that we can learn from how dragonflies do this that we can then bring to the next generation of missiles, or maybe even the next-next generation of missiles?” Chance said. By developing an artificial neural network that mimics a dragonfly's ability to hunt and then applying it to missile capabilities that rely on computation-heavy systems, one could reduce the size, weight and power needed for a missile's onboard computers; improve intercept techniques for targets such as hypersonic weapons; and home in on targets using simpler sensors. If the model of a dragonfly's neural circuit developed through Chance's research shows enough promise, she would then pass the information to scientists, who would try to directly apply it to weapons systems. One of the greatest leaps involves adapting an algorithm to handle the speed at which a missile flies. While a dragonfly is fast, it's not nearly as fast as a missile. Animal brains process information significantly slower than a computer, so it's possible computations can be sped up to better align with the speed at which a missile approaches targets. “The hope is that even if the algorithm isn't wildly successful, you might be able to say something about what you can get away with in terms of what types of capabilities you give the next generation of weapons,” Chance said. The model she's building is several steps removed from implementation onto a weapon. “I would consider the project complete when we have a viable model — ‘viable' meaning it does interception — and a bonus if it's neurobiologically plausible. There is no reason to force that for this type of research, but only because it doesn't necessarily matter; so something biologically inspired that works I would consider a success.” https://www.c4isrnet.com/land/2019/08/05/can-a-dragonfly-teach-a-missile-how-to-hunt/

  • How Army network modernization efforts ensure equipment works with allies

    How Army network modernization efforts ensure equipment works with allies

    Andrew Eversden A critical piece of the U.S. Army's network modernization push is ensuring its systems work with allies. In future battles, the Army will not fight alone; it will be joined by coalition partners, as well as other U.S. services. As the Army moves to improve its integrated tactical network, it must ensure that its network tools work with coalition and service partners The Army recently completed a critical design review of Capability Set '21 a set of new network tools that will be delivered to soldiers next year. The service is in the first phase of procuring the new capabilities. A “key factor” involved in delivery to soldiers at the battalion level and below is a move to a 75 percent “secure but unclassified” network that provides improved communication between coalition partners, said Col. Garth Winterle, project manager for tactical radios at the Army's Program Executive Office Command, Control, Communications-Tactical. “We're moving off of an all-secret network to one that's a lot more flexible and actually encourages coalition interoperability,” Winterle said. One opportunity to test interoperability was Defender Europe 2020, which was meant to be one of the largest European exercises involving both the U.S. Army and NATO allies, but had to be scaled down due to the coronavirus pandemic. Still, the Army was able to test interoperability. There were a series of pre-Defender Europe exercises to assess capabilities “to inform future network design,” according to Justine Ruggio, director of communications for the Network Cross-Functional Team at Army Futures Command. These assessments included several pieces of Capability Set '21, including communications exercises and validation exercises with the Army's fielded Command Post Computing Environment software, Tactical Server Infrastructure and Commercial Coalition Equipment “to enable the use of the Mission Partner Environment, which allowed all participants to share classified information during the exercise, including the Polish and U.K.,” Ruggio said. During the pre-Defender Europe tests, “we were able to bridge the Polish and U.K. unit into an integrated command structure using our secret releasable network and create that common command-and-control picture,” Col. Lesley Kipling, the mission command lead and Army National Guard liaison officer to the Network CFT, said in an interview with C4ISRNET. Secret but releasable information is classified at the secret level and can be released to certain coalition partners who have sufficient clearance from their home country. An exercise scheduled for next year, called Warfighter 21-4, will allow for additional interoperability assessments with U.K. and French forces. According to Ruggio, one focus area will be on interoperability using the Network CFT's DevOps model to iterate the Command Post Computing Environment, continue to assess Commercial Coalition Equipment and evaluate the Mission Partner Environment. The event will be aligned with Capability Set '23, the next iteration of network tools. Kipling added that the cross-functional team and its partners are “continuing” to work on policies and training for properly connecting to a coalition network “so that it's not learning on the fly, but that these procedures and policies are codified in a way that they can be standardized and any user can execute whenever they're put in a situation,” she said. Brig. Gen. Joseph Papenfus, chief Information officer and deputy chief of staff of the G6 of U.S. Army Europe, said that the scaled-back nature of Defender Europe did affect network interoperability testing because soldiers were unable to come over from the United States. That means that U.S. Army Europe will focus heavily on European partners during the smaller exercises, Papenfus said, including validating network integration and establishing a secret but releasable network with NATO. “Every opportunity that we have to see how a piece of equipment works within the larger set of the network, we take advantage of that,” Ruggio said. https://www.c4isrnet.com/yahoo-syndication/2020/07/29/how-army-network-modernization-efforts-ensure-equipment-works-with-allies/
