  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/

  Oshkosh, Saudi Arabia’s Al Tadrea launch joint venture to make armored vehicles

  By: Agnes Helou BEIRUT — American firm Oshkosh Defense and Saudi Arabia's Al Tadrea Manufacturing Company have established a joint venture to manufacture armed vehicles in the kingdom. The two companies formed Oshkosh Al-Tadrea Manufacturing, creating “the largest partnership in the history of Saudi armored vehicles,” according to a message on Al Tadrea's official Twitter account. Defense News reported in 2017 that Al Tadrea was in talks with Oshkosh to manufacture armored vehicles in Saudi Arabia. Al Tadrea CEO Fawzi Bin Ayoub Sabri confirmed during an interview that year at the Bahrain International Defence Exhibition and Conference that his company was “"discussing partnerships with many international companies, particularly negotiating with Oshkosh Defense to produce armored vehicles.” Wednesday's online signing ceremony was held between officials and senior executives of the two companies. The joint venture, also known as OTM, will be based in Saudi Arabia, and the kingdom will hold the largest property share, according to a May 14 report by the Saudi Press Agency. “The joint venture will design and provide its first vehicles to be built based on the model of the Oshkosh Defense vehicle in the medium-sized 4×4 Tactical Vehicle (FMTV) category,” the press agency reported. OTM will “develop manufacturing expertise to become a major partner for wheeled tactical vehicle services, [and] it will also provide the necessary services to its customers in the security and military sectors in the Kingdom, through an integrated and sustainable support fleet, as well as activating the supply chains more broadly and more efficiently,” the report read. In a speech during the virtual ceremony, the head of Al Tadrea said: "The current efforts made by the kingdom in the field of industries, especially military industries, demand from us to move forward and follow the government's directions to achieve everything related to homeland security, and to raise the efficiency of military industries and the support of Saudi talents and human capabilities that we rely on by providing job opportunities to the Saudis.” For his part, John Bryant, the president of Oshkosh Defense and the executive vice president of its parent company, Oshkosh Corporation, said that “both Oshkosh Defense and Al Tadrea Manufacturing have worked closely for more than two years to establish this joint venture, by transferring its technology and capabilities. We are very excited to cooperate with this Saudi company with a solid history.” The two firms prepared for this joint venture by providing training opportunities and accreditation certificates to future OTM employees. The training sessions covered manufacturing, repairing and joint maintenance of M-ATVs, which are mine-resistant, ambush-protected vehicles made by Oshkosh and currently in service within the Royal Saudi Land Forces. https://www.defensenews.com/industry/2020/05/14/oshkosh-saudi-arabias-al-tadrea-launch-joint-venture-to-make-armored-vehicles/
