  New US Army radios show anti-jam progress at network experiment

  Andrew Eversden WASHINGTON — The U.S. Army is seeing improvements in anti-jam capabilities in new radios crucial to securing manned-unmanned communications at its annual Network Modernization Experiment. At NetModX '20, which runs from late July to early October at Joint Base McGuire-Dix-Lakehurst in New Jersey, the Army's Combat Capabilities Development Command's C5ISR Center — or Command, Control, Communication, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance Center — is testing the resiliency of the new radios. The effort will help the service observe how they would perform in the field as the Army looks to partner humans and machines. Initial data from the event suggests the two companies involved — Silvus and Persistent Systems — have improved their radio capabilities from last year, specifically in regard to anti-jam, according to Daniel Duvak, chief of the C5ISR Center's Radio Frequency Communications division. But one major challenge is making the radios less detectable as the Army's tactical network team starts to focus on command post survivability — or reducing the electromagnetic signature of command post communications — while not sacrificing latency and throughput. “If you want to make it less detectable, you know oftentimes you have to trade off the throughput or the range or one of those other products,” Duvak said. “So that's the piece and the real technical challenge that they're continuing to work on over the next few months. We've seen progress that they've made in those areas, but that's the piece that they're still working on.” Robert Stevens, an electronics engineer at the Radio Frequency Communications division, told C4ISRNET that the radios are an important piece of the next-generation combat vehicle. And Duvak said the Army's tactical network modernization team — made up of the Network Cross-Functional Team and Program Executive Office Command, Control, Communications-Tactical — wants to use the radios as a mid-tier radio solution. The development and fielding of new science and technology projects can take more than five years; however, the Army wants to speed that up as it seeks to modernize systems in preparation for future conflicts with near-peer adversaries. At last year's Network Modernization Experiment, the C5ISR Center tested several vendors' radios to see where commercial technology stood. Alternative contracting options, like broad agency announcements as well as cooperative research and development agreements, have proved critical to quickening radio development. Under the contracting mechanisms, vendors and the Army have more flexibility to experiment with radios and make iterative modifications as requirements change. Duvak said this is different from how the Army did business years ago, when it would award yearslong contracts but eventually receive radios that no longer met current requirements. “What we were able to do at this program was, in just about a year and a half of development time, take a couple of those products that we saw that were very promising and we were able to add and actually fund vendors to enhance those radios with those resiliency features that we were just talking about for the contested environment,” Duvak said. “Things like making them anti-jam, or more difficult for the adversary to jam, making them more difficult for the adversary to detect or intercept our communications.” Duvak said the Army wants the new radio capabilities for Capability Set '23, a collection of new tactical network tools to be fielded to soldiers in fiscal 2023. The resiliency of communications is critical as the tactical network modernization team pivots to reduce the electronic signature of the service's command post under Capability Set '23. The team is looking to increase bandwidth and reduce latency as part of that set of tools. Preliminary design review for Capability Set '23 is scheduled for April next year. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/09/21/new-us-army-radios-show-anti-jam-progress-at-network-experiment/

  Fincantieri reopens shipyards in Italy

  By: Tom Kington ROME — Italy shipbuilder Fincantieri has reopened its facilities after more than a month of closure due to coronavirus. The state controlled firm shut down on March 16 after talks with unions as the virus swept through Italy — the first Western country to be hit hard. Since then, Italy's death toll has been overtaken by the U.S., but remains the most exposed country in Europe, with more than 25,000 deaths and 187,000 total infections. As the contagion rate slows however, the government is targeting May 4 as the date to relax rigid lockdown rules for the public. Fincantieri was given the go ahead to restart production on Monday — at a reduced pace. At the firm's Riva Trigoso yard in the Liguria region, where 1,800 were employed before lockdown building Italy's final FREMM frigate and PPA vessels for the Italian navy, just 350 will initially return to work, a spokesman said. Of that number, 150 will be Fincantieri staff, while the remainder are maintenance, cleaning and security contractors. A similar policy is being followed at Fincantieri's Muggiano yard, also in Liguria, where 2,600 are normally employed, and where just 200 staff and 200 contractors have returned to continue work for Italy on a logistics vessel, the Vulcano and a new LHD, the Trieste; as well as a corvette for Qatar. “We hope to be back to full personnel numbers by the end of May or the start of June,” said the spokesman. In the meantime, safety precautions will be taken, including staggered entrances to the yards for staff, obligatory masks and gloves at work, temperature checks at entrances to spot fever sufferers and in-house medical staff. Each staff member will be given a packet of 20 masks per week so they can change them multiple times during each day. “We are planning buses to get staff to work so they don't have to use public transport,” said the spokesman. Similar measures will be taken at Fincantieri's other yards in Italy, which build cruise ships. During the shutdown, the firm's 8,900 staff were kept at home through use of vacation time, furloughs and home working. By contrast, Italian state defense group Leonardo did not close during the lockdown, although many staff worked from home when possible. A deal was struck with unions to introduce social distancing and cleaning at facilities in Italy, and no staff were furloughed, a spokeswoman said. Separately, the Italian government has reconfirmed Leonardo CEO Alessandro Profumo in his role after his mandate ended. The government did however appoint a new chairman, Luciano Carta, who moves from his post as director of Italy's foreign intelligence service. He replaces Gianni De Gennaro, who was head of the government department overseeing Italy's foreign and domestic intelligence services between he joined Leonardo in 2013. https://www.defensenews.com/coronavirus/2020/04/22/fincantieri-reopens-shipyards-in-italy
