Air Force to link F-35, F-22 in ‘connect-a-thon’ experiment
By: Aaron Mehta
WASHINGTON — The U.S. Air Force is preparing an experiment it hopes will link the F-22 and F-35 fighter jets, the first in a series of experiments that service acquisition head Will Roper has dubbed “connect-a-thons.”
The experiments are to happen every four months, starting in December. The goal is to identify a fleet of aircraft with a communications issue, invite voices from inside and outside the Pentagon to offer solutions, and then test those offerings in a live experiment.
“We're making it up as we go, right? There's never been anything like this,” Roper said at a breakfast hosted by the Defense Writers Group. “We need a way for people to propose connections and get into the pipeline. So I wouldn't be surprised at all if it ends up being like a pitch day ... having a proposal process where we review the maturity of the tech versus the benefit to the war fighter. We would do the former, our operators would do the latter."
“And what I love about this is it's kind of a competition within the joint force," he added. "We're going to be looking for the fast movers to volunteer, then we'll be looking at the fast followers.”
The first event, hosted by North American Aerospace Defense Command and U.S. Northern Command, will feature an attempt to allow the F-22 and F-35 to share battlespace — a long-sought capability.
The F-22 was built with an older data link that can't match up with the Multifunction Advanced Data Link, or MADL, system used on the newer F-35; while the F-35 can receive data through Link 16, it can't share the data back — a key capability given the envisioned role of the F-35 as a major sensor for the future Air Force.
For the test, the service will use what Roper called a “Babel Fish-like translator” under the working name of GatewayOne to serve as a “universal translator” for the two jets. The first test, in December, will feature the equipment on a pole on a test range, with the jets pinging their information back and forth from that fixed location.
Should that system work well, in four months Roper plans to put GatewayOne onto a Valkyrie drone, a system designed by Kratos to be cheap enough to be disposable in a battlefield situation. It's not the first time a drone has been used as a link between the two fighters: In 2017, Northrop Grumman pitched its Global Hawk unmanned system, equipped with a new radio, to act as a translator between the aircraft.
Future connect-a-thons currently planned include linking SpaceX's Starlink satellites with KC-135 aerial refueling aircraft in an effort to show commercial communications can work with military aircraft; Roper said the KC-135 community volunteered because the tanker aircraft is perpetually seeking more bandwidth.
Roper also expects the F-16 community — which he called “very innovative, agile operators” who understand they need to keep an aging plane relevant — to “sign up wholesale” for tests in the future.
The acquisitions chief said he is committed to keeping the four-month schedule going, in part because it means if the technology isn't satisfactory, the service will know quickly and be able to move onto something else.
“The good news about that is [Congress and the Pentagon] don't really have to believe us for very long. Just let us get through a few connect-a-thon cycles,” Roper said. “And if we're failing miserably, then that should tell you something about the future of the program.”

NATO chief seeks technology gains in alliance reform push
Sebastian Sprenger COLOGNE, Germany — As NATO officials hash out reform proposals aimed at reinvigorating the alliance, there will be a dedicated push to enhance military technology development among member states, Secretary General Jens Stoltenberg announced this week. “As part of NATO 2030, I intend to put further proposals on the table to maintain our technological edge, to develop common principles and standards for new technologies, and to enhance cooperation between allies in areas like joint research and development,” Stoltenberg said during a speech at the Globsec think tank's Bratislava Forum event. The NATO 2030 drill encompasses various strands of analyses by experts inside and outside the alliance command structure. The reform push goes back to a resolution from the 2019 London summit, which tasked the Norwegian prime minister at the time to lead a “reflection process” that would incorporate new threats like cyberwar, the rise of China, Russian saber-rattling, climate change and terrorism. Over the summer, Stoltenberg unveiled a new political tack emanating from the NATO 2030 study, postulating that the alliance would strive to increase its global reach, including in the Indo-Pacific. “Military strength is only part of the answer,” Stoltenberg said in a June speech. “We also need to use NATO more politically.” He reiterated that objective this week, saying the alliance would seek deeper ties with “like-minded” nations outside of NATO. Resilience is another key prong of the reform agenda, and Stoltenberg previewed a new push for member states to shore up their defenses against potentially hostile forces seeking to undermine the alliance through the back door. Such measures could come in the form of a common monitoring regime for keeping foreign investors from snapping up “critical infrastructure, companies and technologies,” Stoltenberg said. “And we should agree common principles and whether to export technologies that we rely on for our security,” he added. Also on the docket in the course of the reform process is a new strategic concept that would replace the existing version dating from 2010, Stoltenberg announced. https://www.defensenews.com/global/europe/2020/10/09/nato-chief-seeks-technology-gains-in-alliance-reform-push/

Can AI help limited information have endless potential?
By: Kelsey D. Atherton Humans are remarkably good at choosing to act on limited information. Computers, less so. A new DARPA program wants to train artificial intelligence to process and evaluate information like humans do, and produce actionable results on far smaller datasets than presently done. It's a program of such important DARPA's giving it VIP status, or a least VIP as an acronym: Virtual Intelligence Processing. “Successful integration of next-generation AI into DoD applications must be able to deal with incomplete, sparse and noisy data, as well as unexpected circumstances that might arise while solving real world problems,” reads a solicitation posted June 14. “Thus, there is need for new mathematical models for computing leading to AI algorithms that are efficient and robust, can learn new concepts with very few examples, and can guide the future development of novel hardware to support them.” To create these mathematical models, DARPA wants partners to look inward, creating AI inspired by the robust and massive parallelism seen in the human neocortex. If it is the architecture of the brain that makes humans so especially skilled at processing information quickly, then it is an architecture worth studying. “In order to reverse engineer the human brain,” the solicitation continues, calmly, “we need to apply new mathematical models for computing that are complete and transparent and can inform next-generation processors that are better suited for third-wave AI.” It is DARPA's nature to inject funding into problem areas it sees as both yielding future results and not presently served by the market, and this is not different. The solicitation explicitly asks for mathematical models that have not already been the focus of AI development. It's also looking for models that can inform the development of future hardware, rather than programs that can run on existing machines. DARPA is interested in how the hardware works in simulation, but wants partners to hold off on actually making the hardware for the model. So, the plan goes: create a mathematical model, inspired by brains, to process information on a small and limited data set, and then design it for hardware that doesn't exist yet. Easy as that sounds, the solicitation also asks proposers to talk about the limitations of the algorithms when applied to military tasks, and specifically limitations related to accuracy, data, computing power and robustness. Working from limited information is an expected future of military machines going forward. Between electronic warfare, denied environments and the very nature of battlefield events as rare and hard to record moments, doing more with on-board processing of limited data should enable greater autonomy. Even in the rare case where a weapon system transmits data back for algorithm refinement, that data set will be orders of magnitude smaller than the big data sets used to train most commercial machine learning tools. Should a proposer's idea be accepted and they follow through both Phase 1 and Phase 2 of the project, the total award is set at $1 million. A tidy sum, for anyone who can figure out the math to make a future computer run on sparse information as effectively as a human brain. https://www.c4isrnet.com/artificial-intelligence/2019/06/18/can-brain-inspired-ai-run-on-lean-data/
