2015/03/26 Wanted: Technologies to Enable Automated Lookouts for Unmanned Surface Vessels DARPA’s Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program seeks to develop a new type of unmanned surface vessel that could independently track adversaries’ ultra-quiet diesel-electric submarines over thousands of miles. One of the challenges that the ACTUV program is addressing is development of autonomous behaviors for complying with the International Regulations for Preventing Collisions at Sea, known as COLREGS. Substantial progress has been made in developing and implementing those behaviors. Currently, ACTUV’s system for sensing other vessels is based on radar, which provides a “90% solution” for detecting other ships. However, radar is less suitable for classification of the type of other vessels, for example determining whether the vessel is a powered vessel or a sailboat. Additionally, one of the requirements of COLREGS is to maintain “a proper look-out by sight and hearing.”
2015/03/19 Petaflops On Desktops: Ideas Wanted For Processing Paradigms That Accelerate Computer Simulations Whether designed to predict the spread of an epidemic, understand the potential impacts of climate change, or model the acoustical signature of a newly designed ship hull, computer simulations are an essential tool of scientific discovery. By using mathematical models that capture the complex physical phenomena of the real world, scientists and engineers can validate theories and explore system dynamics that are too costly to test experimentally and too complicated to analyze theoretically. Over the past half century, as supercomputers got faster and more powerful, such simulations became ever more accurate and useful. But in recent years even the best computer architectures haven’t been able to keep up with demand for the kind of simulation processing power needed to handle exceedingly complex design optimization and related problems.
2015/03/23 Tern Continues Progress toward Enabling Small Ships to Host Their Own Unmanned Air Systems DARPA has awarded prime contracts for Phase 2 of Tern, a joint program between DARPA and the U.S. Navy’s Office of Naval Research (ONR). The goal of Tern is to give forward-deployed small ships the ability to serve as mobile launch and recovery sites for medium-altitude, long-endurance unmanned aerial systems (UAS). These systems could provide long-range intelligence, surveillance and reconnaissance (ISR) and other capabilities over greater distances and time periods than is possible with current assets, including manned and unmanned helicopters. Further, a capacity to launch and retrieve aircraft on small ships would reduce the need for ground-based airstrips, which require significant dedicated infrastructure and resources. The two prime contractors selected by DARPA are AeroVironment, Inc., and Northrop Grumman Corp.
2015/03/26 DARPA Shares Its Vision for the Future DARPA today released Breakthrough Technologies for National Security, a biennial report summarizing the Agency’s historical mission, current and evolving focus areas and recent transitions of DARPA-developed technologies to the military Services and other sectors. The report’s release coincided with testimony by DARPA Director Arati Prabhakar before the Emerging Threats and Capabilities Subcommittee of the House Armed Services Committee, at a hearing entitled “Department of Defense Fiscal Year 2016 Science and Technology Programs: Laying the Groundwork to Maintain Technological Superiority.” The full report is available at http://go.usa.gov/3rut4.
