Europeans start work on next-generation combat ship for the 2040s

Based on feedback from European Union member states, the requirement could be for a vessel with a displacement of 8,000 metric tons or more.

    DARPA: Teaching AI Systems to Adapt to Dynamic Environments

    Current AI systems excel at tasks defined by rigid rules – such as mastering the board games Go and chess with proficiency surpassing world-class human players. However, AI systems aren't very good at adapting to constantly changing conditions commonly faced by troops in the real world – from reacting to an adversary's surprise actions, to fluctuating weather, to operating in unfamiliar terrain. For AI systems to effectively partner with humans across a spectrum of military applications, intelligent machines need to graduate from closed-world problem solving within confined boundaries to open-world challenges characterized by fluid and novel situations. To attempt this leap, DARPA today announced the Science of Artificial Intelligence and Learning for Open-world Novelty (SAIL-ON) program. SAIL-ON intends to research and develop the underlying scientific principles and general engineering techniques and algorithms needed to create AI systems that act appropriately and effectively in novel situations that occur in open worlds. The program's goals are to develop scientific principles to quantify and characterize novelty in open-world domains, create AI systems that react to novelty in those domains, and to demonstrate and evaluate these systems in a selected DoD domain. A Proposers Day for interested proposers is scheduled for March 5, 2019, in Arlington, Virginia: https://go.usa.gov/xEUWh “Imagine if the rules for chess were changed mid-game,” said Ted Senator, program manager in DARPA's Defense Sciences Office. “How would an AI system know if the board had become larger, or if the object of the game was no longer to checkmate your opponent's king but to capture all his pawns? Or what if rooks could now move like bishops? Would the AI be able to figure out what had changed and be able to adapt to it?” Existing AI systems become ineffective and are unable to adapt when something significant and unexpected occurs. Unlike people, who recognize new experiences and adjust their behavior accordingly, machines continue to apply outmoded techniques until they are retrained. Given enough data, machines are able to do statistical reasoning well, such as classifying images for face-recognition, Senator said. Another example is DARPA's AI push in self-driving cars in the early 2000s, which led to the current revolution in autonomous vehicles. Thanks to massive amounts of data that include rare-event experiences collected from tens of millions of autonomous miles, self-driving technology is coming into its own. But the available data is specific to generally well-defined environments with known rules of the road. “It wouldn't be practical to try to generate a similar data set of millions of self-driving miles for military ground systems that travel off-road, in hostile environments and constantly face novel conditions with high stakes, let alone for autonomous military systems operating in the air and on sea,” Senator said. If successful, SAIL-ON would teach an AI system how to learn and react appropriately without needing to be retrained on a large data set. The program seeks to lay the technical foundation that would empower machines, regardless of the domain, to go through the military OODA loop process themselves – observe the situation, orient to what they observe, decide the best course of action, and then act. “The first thing an AI system has to do is recognize the world has changed. The second thing it needs to do is characterize how the world changed. The third thing it needs to do is adapt its response appropriately,” Senator said. “The fourth thing, once it learns to adapt, is for it to update its model of the world.” SAIL-ON will require performers and teams to characterize and quantify types and degrees of novelty in open worlds, to construct software that generates novel situations at distinct levels of a novelty hierarchy in selected domains, and to develop algorithms and systems that are capable of identifying and responding to novelty in multiple open-world domains. SAIL-ON seeks expertise in multiple subfields of AI, including machine learning, plan recognition, knowledge representation, anomaly detection, fault diagnosis and recovery, probabilistic programming, and others. A Broad Agency Announcement (BAA) solicitation is expected to be posted in the near future and will be available on DARPA's FedBizOpps page: http://go.usa.gov/Dom https://www.darpa.mil/news-events/2019-02-14

    Rheinmetall expects German ammunition order worth billions soon

    Rheinmetall expects to strike an ammunition deal worth billions of euros with the German government in the coming weeks and will deliver the first 35mm rounds for Gepard anti-aircraft guns to Ukraine in July, its CEO, Armin Papperger, said on Thursday.

    Lockheed Martin-Built AEHF-5 Protected Communications Satellite Now in Transfer Orbit

    The Lockheed Martin (NYSE:LMT)-built AEHF-5 satellite is now responding to the squadron's commands as planned. The squadron began "flying" the satellite shortly after it separated from its United Launch Alliance Atlas V 551 rocket approximately 5 hours and 40 minutes after the rocket's successful 6:13 a.m. ET liftoff. AEHF-5 complete a geostationary ring of five satellites delivering global coverage for survivable, highly secure and protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms. Besides U.S. forces, AEHF also serves international partners including Canada, the Netherlands and the United Kingdom. "This fifth satellite adds an additional layer of flexibility for critical strategic and tactical protected communications serving the warfighter. This added resilience to the existing constellation will help ensure warfighters can connect globally to communicate and transmit data at all times," said Mike Cacheiro, vice president for Protected Communications at Lockheed Martin Space. "In the weeks ahead, AEHF-5 will move towards its operational orbit, deploy all of its solar arrays and antennas, and turn on its powerful communications payload for a rigorous testing phase prior to hand over to the Air Force." AEHF-5, with its advanced Extended Data Rate (XDR) waveform technology, adds to the constellation's high-bandwidth network. One AEHF satellite provides greater total capacity than the entire legacy five-satellite Milstar communications constellation. "Individual data rates increase five-fold compared to Milstar, permitting transmission of tactical military communications, such as real-time video, battlefield maps and targeting data," said Cacheiro. "AEHF affords national leaders anti-jam, always-on connectivity during all levels of conflict and enables both strategic and tactical users to communicate globally across a high-speed network that delivers protected communications in any environment." Lockheed Martin designed, processed and manufactured all five on-orbit AEHF satellites at its advanced satellite manufacturing facility in Sunnyvale, California. The next AEHF satellite, AEHF-6, is currently in full production in Silicon Valley and is expected to launch in 2020. The AEHF team includes the U.S. Air Force Military Satellite Communications Systems Directorate at the Space and Missile Systems Center, Los Angeles Air Force Base, Calif. Lockheed Martin Space, Sunnyvale, Calif., is the AEHF prime contractor, space and ground segments provider as well as system integrator, with Northrop Grumman Aerospace Systems, Redondo Beach, Calif., as the payload provider.
