  Defense supply chains should support allies, but favor domestic producers

  The concept is simple: buy American when you can, buy from trusted allies when you must.

  The Army wants a better way to update software, buy smarter

  By: Mark Pomerleau The Army is holding what it calls software solariums as a way to improve the business side of the service's multi-billion software efforts during the life of programs. “Software has become both a critically important element to readiness and a critically under-managed element of our capability portfolio,” Maj. Gen. Randy Taylor, commander of Communications and Electronics Command, said at the event held May 22-23. “Cohesive software management is a necessary enabler to maintaining overmatch in the multi-domain battle.” Providing software updates to units in austere field locations can be challenging. Prolonging such updates can make the systems they run on vulnerable. The Army has sought to develop new and innovative ways for automated software updates to these units. As the Army is also undergoing major IT modernization, both to its tactical and enterprise networks, software becomes a critical enabler in that future end state. “I believe that we are literally in the midst of the largest modernization of our networks,” Lt. Gen. Bruce Crawford, the Army CIO who began the software solariums as commander of CECOM, said at the recent event. “And that's all of our networks, from the tactical to the enterprise, to the business to the intelligence systems in the last 30 years.” With these modernization efforts, the Army realizes it must be better stewards of overall software costs. “We've got to be more holistic on how we approach this, especially when you consider that we, the U.S. taxpayer, spend 55 to 70 percent of a program's lifecycle on that post-acquisition and post-operations sustainment. That's a pretty big bill,” Taylor said. During a March conference, Crawford noted the service spends about $3 billion over a five year period on enterprise software sustainment. The previous solariums, officials said, have included new patching solutions and a goal to have no more than two fielded software baselines at any one time for all programs of record. Army leaders said CECOM will coordinate with stakeholders to finalize recommendations in the coming months. Those goals then will be submitted to the Army level Information Technology Oversight Council for approval and implementation. https://www.c4isrnet.com/it-networks/2018/06/14/the-army-wants-a-better-way-to-update-software-buy-smarter/

  Army Looks to Nature to Improve Body Armor

  By ARL Public Affairs Future soldiers will be better protected in combat by stronger and lighter body armor thanks to innovative work at the U.S. Army Research Laboratory. Materials science engineers are using nature as the inspiration for breakthroughs in additive manufacturing. “My project is to design a system that can 3-D print armor ceramics that will allow production of parts with graded structures similar to an abalone structure in nature that will improve the ceramic armor's toughness and survivability with lower weight,” said Joshua Pelz, a materials science and engineering doctoral candidate at the University of California San Diego. He spent this summer working with Army scientists at ARL's Rodman Materials Science Laboratory at APG to design and build a unique 3-D printer. Two syringes containing distinct, viscous ceramic slurries are connected to a custom-made auger and print head. Pelz took advantage of his computer programming skills to hack into the 3-D printer, tricking it into using its own fan controls to manipulate the ratio of materials being printed. He designed a custom auger and print head and even used the same 3-D printer to create those parts. “Josh found a way to implement our ideas into that machine, take apart machine, take out the polymer FDM heads that are built into it, start to look at how to design the machine to incorporate our ceramic slurries and print those slurries into the head but then he had to do a lot of really basic work looking at how to actually hack the machine,” said Dr. Lionel Vargas-Gonzalez, Ceramics Synthesis and Processing team lead at the laboratory. “We've got people like Josh who were very gifted and talented and can bring all that kind of capability and use a lot to our advantage it's a huge benefit for us.” Current processing techniques used to create ceramic armor are limited by how engineers can combine materials into a stronger composite material. “For ceramics, that's a bit of a challenge because with you can't really do what a one-step additive manufacturing process like you could if a metal or a polymer,” Vargas-Gonzalez said. “We see this as a next avenue for armor because we're going to be able to, in theory, design armor in a way that we can attach multiple materials together into a single armor plate, and be able to provide ways for the armor to perform better than it can be just based on one material alone.” Full article: http://science.dodlive.mil/2018/10/01/army-looks-to-nature-to-improve-body-armor/
