  White House sets ‘new direction’ in biodefense strategy

  By: Robert Burns, The Associated Press WASHINGTON — The Trump administration on Tuesday released a new biodefense strategy that it said takes a more comprehensive approach to preparing the nation for deliberate biological attacks and natural outbreaks of infectious disease. The goal of the strategy, which was required by Congress, is to more effectively prevent, prepare for and respond to biological threats, which the document said are "among the most serious threats" facing the U.S. and the world. "Biological threats emanate from many sources, and they know no borders," Trump said in a written statement. "They have great potential to disrupt the economy, exact a toll on human life, and tear at the very fabric of society." Trump said his administration's plan takes a "new direction" with a more coordinated, centralized approach based on lessons learned from past incidents such as the West Africa Ebola epidemic of 2014. The Department of Health and Human Services is designated as the lead agency in coordinating federal biodefense actions and assessing whether the plan is working. A privately sponsored group that has studied biodefense issues since 2014 applauded the White House's strategy. The Blue Ribbon Study Panel on Biodefense has warned that the U.S. is dangerously vulnerable to a large-scale biological attack and has urged Washington to develop a more comprehensive strategy. "The White House made a great start with the implementation plan they included with the strategy," said Tom Ridge, the former Pennsylvania governor who is co-chairman of the Blue Ribbon Study Panel. "We look forward to the White House assigning responsibilities for each element of this plan to specific federal departments and agencies, and establishing timelines for their completion." At a White House briefing, John Bolton, the president's national security adviser, told reporters there is "no particular immediate threat" of biological attack. Alex Azar, the secretary of Health and Human Services, told reporters the threats are "very real and they're growing." He said the strategy is the first to include naturally occurring threats like the Ebola virus. Previous approaches focused on the threat of terrorists unleashing deadly germs or a nation such as North Korea launching a biological attack. https://www.federaltimes.com/management/2018/09/18/white-house-sets-new-direction-in-biodefense-strategy

  The U.S. Department of Defense selects BAE Systems to help develop and deliver next generation mission technologies

  The U.S. Department of Defense (DoD) has selected BAE Systems to compete for future research and development (R&D) task orders awarded under a nine-year, indefinite delivery/indefinite quantity (IDIQ) contract. The contract provides fast, flexible, low-cost solutions across technical disciplines to meet the current and future technology needs of the U.S. military. “This large-scale contract provides us with a tremendous opportunity to reach across BAE Systems and leverage our own internal research and development investments to help the DoD solve its most difficult mission challenges,” said Al Whitmore, president of BAE Systems' Intelligence & Security sector. “We are excited to help the government leverage innovations in artificial intelligence, machine learning, and directed energy technologies to enhance the security and effectiveness of our warfighters across physical and digital domains.” BAE Systems is one of 15 companies selected by the Defense Technical Information Center to compete for future R&D and support task orders expected to exceed $15 million. These task orders will be awarded by the Air Force Installation Contract Agency/KD Offutt AFB, Nebraska and support the DoD Information Analysis Center Program Management Office. The ceiling value for all future work awarded under the IDIQ is $28 billion. BAE Systems delivers a broad range of solutions and services enabling militaries and governments to successfully carryout their missions. The company provides large-scale systems engineering, integration, and sustainment services across air, land, sea, space, and cyber domains. BAE Systems takes pride in its support of national security and those who serve. https://www.baesystems.com/en/article/the-u-s--department-of-defense-selects-bae-systems-to-help-develop-and-deliver-next-generation-mission-technologies

  Is this the new wave of submerged communications?

  By: Kelsey Atherton The ocean hides what it contains, and it is in that hiding that submarines have their power. Lurking under seas, at first with just enough capability for an attack run and now with the ability to lurk for months at a time, submarines remain power out of reach, unseen until engaged in combat or resupplying in a friendly port. That stealth comes at a cost, however, besides the simple perils of existing underwater. When submerged, submarines are more or less on their own until they resurface again, since radio waves do not travel well through seawater. Or they are for now. New research by MIT, presented at a conference in late August, devised a way for submerged submarines to communicate wirelessly with people on the surface by combining hydroacoustics and acoustic radars. Presently, submarines communicate either across normal radio frequencies when surfaced or through hydroacoustic signals and listening posts underwater that can transmit the messages back to counterparts on shore. Very and extremely low-frequency radio waves can be transmitted in a way that submarines can listen to below the surface, but it's a one-way form of communication, from stations on land to submarines. To get something responsive, with the flexibility to communicate away from static seabed hydrophones, needs something else. Specifically, it needs a way to combine hydroacoustic transmission from the submarine through water that can then be converted into a useful data. “We present a new communication technology, translational acoustic-RF communication (TARF),” write paper authors Francesco Tonolini and Fadel Adib of the MIT Media Lab. “TARF enables underwater nodes to directly communicate with airborne nodes by transmitting standard acoustic signals. TARF exploits the fact that underwater acoustic signals travel as pressure waves, and that these waves cause displacements of the water surface when they impinge on the water-air boundary. To decode the transmitted signals, TARF leverages an airborne radar which measures and decodes these surface displacements.” In testing, they demonstrated that the communication technique can transfer data at standard underwater bitrates up to 400bps, and even do so with surface waves 6.3 inches crest-to-crest, or 100,000 times larger than the surface perturbations made by the acoustic transmitter. Right now, this communication is one-way. While the signal transmitted up from the water produces useful information at the boundary with the air, a signal transmitted through the air downwards would disintegrate on integration with water. This one-way is distinct from previous forms of communication with submarines, however, as it lets the submarine talk without revealing its position to surface sensors. Despite the limitations, and the earlierness of the research, Tonolini and Adlib see a bright future for the technology, as a way to enable a host of new technology in machines. The technology, they write, can enable “many applications including submarine-to-drone communication, deep-sea exploration, and subsea IoT (Internet of Things). https://www.c4isrnet.com/c2-comms/2018/08/28/mit-discovers-way-for-submarines-to-talk-to-drones
