DARPA's Squad X Experimentation program aims to demonstrate a warfighting force with artificial intelligence as a true partner. In a recent field test, the program worked with U.S. Marines at the Air Ground Combat Center in Twentynine Palms, California, to track progress on two complementary systems that allow infantry squads to collaborate with AI and autonomous systems to make better decisions in complex, time-critical combat situations. “We are in a race with potential adversaries to operationalize autonomy, and we have the opportunity to demonstrate autonomy in a way that we don't believe any nation in the world has demonstrated to date,” said Lt. Col. Phil Root (USA), the Squad X program manager in DARPA's Tactical Technology Office. “Developing hardware and tactics that allow us to operate seamlessly within a close combat ground environment is extremely challenging, but provides incredible value.” The exercises in early 2019 in Twentynine Palms followed experiments in 2018 with CACI's BITS Electronic Attack Module (BEAM) Squad System (BSS) and Lockheed Martin's Augmented Spectral Situational Awareness and Unaided Localization for Transformative Squads (ASSAULTS) system. The two systems, though discrete, focus on manned-unmanned teaming to enhance capabilities for ground units, giving small squads battalion-level insights and intelligence. In the most recent experiment, squads testing the Lockheed Martin system wore vests fitted with sensors and a distributed common world model moved through scenarios transiting between natural desert and mock city blocks. Autonomous ground and aerial systems equipped with combinations of live and simulated electronic surveillance tools, ground radar, and camera-based sensing provided reconnaissance of areas ahead of the unit as well as flank security, surveying the perimeter and reporting to squad members' handheld Android Tactical Assault Kits (ATAKs). Within a few screen taps, squad members accessed options to act on the systems' findings or adjust the search areas. Between Lockheed Martin's two experiments to date, Root says the program-performer team identified a “steady evolution of tactics” made possible with the addition of an autonomous squad member. They also are focused on ensuring the ground, air, and cyber assets are always exploring and making the most of the current situation, exhibiting the same bias toward action required of the people they are supporting in the field. CACI's BEAM-based BSS comprises a network of warfighter and unmanned nodes. In the team's third experiment, the Super Node, a sensor-laden optionally-manned, lightweight tactical all-terrain vehicle known as the powerhouse of the BEAM system, communicated with backpack nodes distributed around the experiment battlespace – mimicking the placement of dismounted squad members – along with an airborne BEAM on a Puma unmanned aerial system (UAS). The BSS provides situational awareness, detects of electronic emissions, and collaborates to geolocate signals of interest. AI synthesizes the information, eliminating the noise before providing the optimized information to the squad members via the handheld ATAK. “A human would be involved in any lethal action,” Root said. “But we're establishing superior situational awareness through sufficient input and AI, and then the ability to do something about it at fast time scales.” The Squad X program has moved quickly through development and is already well along the transition path, due in large part to the program's focus on partnering with the services to ensure real-world efficacy. For the CACI system, that included an opportunity to test the technology downrange to get real-world information, not simulation. At the most recent experiment with the BSS, service representatives used the system to locate and identify objectives in real time. For both systems, feedback has included a desire for a user interface so intuitive that training takes an hour or less and any available action is accessible in two screen taps. Staff Sergeant Andrew Hall with the Marine Corps Tactics and Operations Group (MCTOG), an advisory teammate to DARPA's Squad X Experimentation program, says the ability to provide early input will guard against developing a product that either isn't used or is used improperly. “The feedback process, in conjunction with the actual experimentation, gives the Marines the ability to use the technology and start seeing what it can do and, more specifically, what it can't do,” Hall said. With the conclusion of third experiment, the CACI system is moving into Phase 2, which includes an updated system that can remain continuously operational for five or more hours. Lockheed Martin will conduct its next experiment in the fall of 2019. CACI's BEAM system is already operational, and the Army has committed to continue its development at the completion of Squad X Phase 2. The Army is set to begin concurrent development of the Lockheed Martin ASSAULTS system in fiscal years 2019 and 2020, and then, independent of DARPA, in fiscal year 2021. https://www.darpa.mil/news-events/2019-07-12

By: Alexander Bratersky MOSCOW — Rostec announced this week it has begun developing the MiG-41, a fifth-generation fighter jet set to replace Russia's MiG-31 jets currently in service. However, amid a number of other ongoing military aerospace projects, experts are questioning whether industry has the resources to produce the aircraft by its deadline of 2030. The MiG-31 fleet entered service in 1980 under the Soviet Armed Forces and was upgraded in 1990 to become the MiG-31BM. The MiG-41, originally developed by Rostec subsidiary United Aircraft Corporation, has long been expected to replace the aging jets. Work on the new aircraft started in 2010 with UAC's Mikoyan design bureau and Sokol aviation production plant, based in Nizhny Novgorod, about six hours' drive from Moscow. According to Russian news reports, the MiG-41 will be equipped with stealth technology, reach a speed of Mach 4-4.3, carry anti-satellite missiles, and be able to perform tasks in Arctic and near-space environments. If it enters service, the MiG-41 will be the country's second fifth-generation fighter after the Su-57, which was developed by UAC subsidiary Sukhoi Company and had its first flight test in 2010. The Su-57 crashed during a flight test in December 2019. The pilot has survived, leaving the plane on the catapult chair. Defense officials told the Vedomosti newspaper at that time that technical mishaps in the control system might have caused the accident. A governmental commission was founded to investigate the accident, but no public report was realized. That same year, the Russian military bought 76 Su-57 planes. The cost of a single Su-57 might be about 3 billion roubles (U.S. $40 million), Izvestia reported that year, citing defense sources. The plane is equipped with the AL-41F1 engine, which is also used on the Su-35 jet. However, the local Lyulka Design Bureau is currently developing a new engine for the Su-57. According to Ruslan Pukhov, the director of the Centre for Analysis of Strategies and Technologies, the primary focus of Russia's defense industry is to develop that engine. That main effort takes away much-needed resources for the new plane, he explained. A London-based analyst echoed Pukhov's concerns, expressing skepticism that Russia “will be able to develop, manufacture and introduce into service [the jet] in anything like the purported time frame.” Douglas Barrie, who focuses military aerospace for the International Institute for Strategic Studies, said Russia's aerospace sector is already committed to numerous projects, including further developing the Su-75, upgrading the Su-34, and modernizing various bombers such as the Tu-160 Blackjack, Tu-22M Backfire and Tu-95. “Some would argue that the sector has already more than enough to try to manage without the additional or a project potentially as complex as a new heavy interceptor, or indeed whether there would be realistic levels of funding for a program,” he said. Defense News contacted the Russian Aircraft Corporation, a subsidiary of UAC involved in the MiG-41 project, but the firm declined to comment on the jet's development. For his part, Pukhov thinks the government should ditch its costly projects and instead appropriate funds to develop drones. “This is the sphere where Russia is still behind,” he said. He added that both China and India will likely want to cooperate on the MiG-41. The latter left a joint project to develop a fifth-generation fighter aircraft based on the Su-57 in 2018. But Barrie questioned the export potential of the MiG-41, saying the number of similar jets being built elsewhere is rapidly growing. “Even if such an aircraft were eventually to be developed, it would — were it to meet the same role as the MiG-31BM Foxhound C — have a very limited export appeal.” https://www.defensenews.com/air/2021/01/29/is-russias-defense-industry-too-busy-to-take-on-another-fighter-jet-project
