  US defense-industry report finds 300 security risks needing 'immediate action'

  by James Langford A sweeping Defense Department review ordered by President Trump has identified roughly 300 gaps in weapon-makers' supply chains that could threaten U.S. military campaigns if they're not corrected, a senior administration official said Thursday. The report, commissioned in July 2017, will be presented to Trump on Friday, and the president is expected to earmark funds available through both the Defense Production Act and a 1939 defense stockpile program to address some of them, the official said. The issues were identified largely at small and midsize firms that have supplied top-line U.S. contractors like Boeing and Lockheed Martin and have been harmed more than their larger customers by cuts in U.S. government spending, the official said. Compiled by 16 working groups with hundreds of subject-matter exports, the report found both fragile markets and weakened companies, situations that could affect the production of devices such as propeller shafts, as well as supplies of raw materials like rocket fuel, ceramics used in body armor, and metals used in combat vehicles. "We have a situation where we've identified a number of vulnerabilities which demand immediate action," the official said. "This administration's hallmark is immediate action, and with this report, there's also a blueprint for actions that will be launched immediately." The review reflects the president's belief that economic security is synonymous with national security, highlighted with the imposition of double-digit tariffs on steel and aluminum earlier this year. Those duties were set under Section 232 of the Trade Expansion Act of 1962, which allows the White House to intervene in markets to protect national security.

  DARPA: Five Teams of Researchers Will Help DARPA Detect Undersea Activity by Analyzing Behaviors of Marine Organisms

  Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities. DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.” The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors. The team led by Northrop Grumman Corporation, under principal investigator Robert Siegel, will record and analyze acoustics from snapping shrimp and optical activity by bioluminescent organisms. The team led by the Naval Research Laboratory, under principal investigator Lenny Tender, will integrate microbial organisms into a sensing platform to detect and characterize biological signals from natural microorganisms that respond to the magnetic signatures of underwater vehicles. The team led by Florida Atlantic University, under principal investigator Laurent Cherubin, will record and analyze vocalization cues from goliath grouper in tropical and subtropical environments. The team led by Raytheon BBN Technologies, under principal investigator Alison Laferriere, will use snapping shrimp as sources of opportunity for long-range detection, classification, and tracking of underwater vehicles. The team led by the University of Maryland Center for Environmental Science, under principal investigator David Secor, will tag black sea bass with sensors to track the depth and acceleration behaviors of schools of fish that are perturbed by underwater vehicles. DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time. DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels. https://www.darpa.mil/news-events/2019-02-15
