    Land Systems Integration Team Is Leader in Model-Based Systems Engineering

    By C. Michaela Judge, Naval Information Warfare Center Atlantic Public Affairs CHARLESTON, S.C. (NNS) -- The Land Systems Integration (LSI) Division at Naval Information Warfare Center (NIWC) Atlantic continues to be an enterprise leader in Model-Based Systems Engineering (MBSE) for their work on land systems modernization and integration. MBSE is an engineering approach that utilizes a common, digital tool suite allowing all team members – from engineer to sponsor – to have awareness, line-of-sight and an understanding of the interaction between the various moving parts across the systems engineering and project lifecycle. LSI’s Vehicular Technology Transition (VTT) team incorporates the full range of MBSE techniques into their systems engineering projects to support the Marine Corps and has had great success in continuing this approach in their daily work. “What makes LSI and our team specifically successful is the depth of knowledge in implementation of using the MBSE Tool Suite,” said Tim Turner, VTT team lead. “Our engineering work isn’t radically different than any other engineering groups across the Command; it’s how we’re putting the data in the system and making it transparent to everyone that needs to have access to it.” Though engineers have been performing systems engineering in some capacity for decades, using this model-based approach provides an added advantage to deliver effective and timely solutions to the warfighter. “Our MBSE Tool Suite is a set of seamlessly integrated engineering lifecycle management tools that work together as one,” said Jacob Witmer, VTT team Military GPS User Equipment (MGUE) project lead. “We use these tools to manage requirements and architectures, plan projects, track changes, manage quality, and provide an enterprise library management system where you catalog, organize, use, reuse, manage, and report on any type of software, technology, or business asset.” In the vehicle transition domain, the VTT team utilized MBSE techniques to solve real-world challenges for the warfighter. Most recently, they used MBSE to conduct global positioning system (GPS) integration work conducted on the Joint-Light Tactical Vehicle, the MGUE Program’s lead platform.  “When we look at all of the people our team has to work with on this integration project, we have to manage a lot of different data, to include where the trucks are manufactured, where GPS is managed, the performance level of the GPS card, the truck integration and more,” said Witmer. “There are a lot of players, managing a lot of data in a lot of different formats from different geographic parts of the country. That’s really what the MBSE Tool Suite is designed to do – manage, connect and link the data to see how they impact each other.”  One cost-avoidance benefit of using the MBSE Tool Suite, in time and man-hours, includes the ability to quickly build reports. “We can build 150-page project requirements documents in three minutes because the data is already in the Tool Suite,” said Ryan Longshore, VTT team technical lead. “There is an investment in time and energy upfront in loading the data, but a report that would take 30 to 90 days is done in a matter of minutes and everything from that project is captured in the report.” The team’s use of MBSE is not only essential to connecting and maintaining data across a project, but also a necessary resource in developing physical models and solutions in a fraction of the time previously needed to fulfill a warfighter requirement.  “Our team works within the Systems Integration Laboratory (SIL) to design and test on multiple vehicular platforms,” said Turner. “The lab allows us to execute MBSE across all team functions, from mission thread to risk analysis or program management.” The team maintains physical models for all of the vehicle platforms they support. When a requirement from a sponsor arrives, the team can use tools within the SIL to design and print a three-dimensional piece of hardware and test it on an existing model before they touch a physical vehicle. The team conducts engineering, mechanical and software-related integration testing and design work all within the laboratory.  “It’s all about testing upfront, learning upfront, failing faster and learning from it and moving on and improving on the design,” said Turner. As the team designs and tests within the lab, they also update the MBSE Tool Suite is to capture lessons learned, integration challenges and real-time project data for all team members to access. “The beauty of the suite being so integrated is that it doesn’t matter what type of systems engineering methodology a project uses, the tools can be tailored to meet a myriad of engineering processes and organizing the data by methodology saves countless hours in digging around trying to find historical artifacts,” said Witmer. The team can now complete an integration project that previously took 18 to 36 months as quickly as six to nine months, without sacrificing quality, thanks to the value of MBSE. With VTT and other teams reaping the benefits of MBSE, NIWC Atlantic created a training and workforce development path to work toward a Command-wide adoption of this method. Communities of interest, industry engagements and training events on MBSE methods are a few of the efforts implemented to date.  The VTT uses these training approaches, to a smaller-scale, to continue to encourage MBSE implementation and help employees understand the power of using a model-based approach to apply agility in executing warfighter solutions. “We’re seeing the benefits and through MBSE my team has the flexibility to fail fast and learn a lot upfront,” said Turner. The team’s success with the MBSE Tool Suite is a Command-wide example of how the transparency and connectivity of engineering data help to provide integration solutions to NIWC Atlantic customers with a high confidence of success. As a part of Naval Information Warfare Systems Command, NIWC Atlantic provides systems engineering and acquisition to deliver information warfare capabilities to the naval, joint and national warfighter through the acquisition, development, integration, production, test, deployment, and sustainment of interoperable command, control, communications, computer, intelligence, surveillance, and reconnaissance, cyber and information technology capabilities. https://www.navy.mil/submit/display.asp?story_id=110447

    Army signs $87 million deal for latest tank killer

    Mike Glenn  The Army signed an $87 million deal with Saab to arm its soldiers with the latest version of the Swedish manufacturing company’s powerful 84mm bunker-busting, Carl-Gustaf anti-tank weapon. The seven-year contract calls for Saab to provide an indefinite number of the shoulder-fired weapons, designated as M3E1, to the military. They will be used by the Army, Marine Corps and elements of U.S. Special Operations Command, company officials said. “The lightweight and effective recoilless rifle ensures readiness on the modern battlefield with multi-role capabilities through a wide array of munitions,” Erik Smith, president and CEO of Saab in the U.S., said in a statement. The latest version of the Carl-Gustaf is 28 percent lighter than its predecessor. The system has been popular with U.S. troops as a combined anti-tank, anti-personnel weapon system since it was first fielded in the late 1980s. The Army decided it would acquire the latest version in 2018. https://www.washingtontimes.com/news/2020/oct/15/army-signs-87-million-deal-latest-tank-killer/

    The Navy is looking at an unmanned helicopter to make its newest ships more lethal — and it just passed the first test

    Christopher Woody The Navy recently completed initial testing of the MQ-8C Fire Scout, an unmanned helicopter capable of carrying three times as much payload as an earlier version. The Navy hopes to deploy the MQ-8C aboard littoral combat ships, augmenting their limited range and firepower. More testing is needed however, and the Navy is still evaluating how the arm the drone helicopter. On June 29, US Navy crews completed the first comprehensive initial operational test and evaluation of the MQ-8C Fire Scout, an unmanned helicopter the Navy hopes will increase the lethality of the service's new littoral combat ships. The aircraft carried out several mission scenarios from the USS Coronado, an LCS commissioned in 2014. The Coronado's crew and members of Air Test and Evaluation Squadron 1 performed simulated engagements in order to review the MQ-8C's target-identification, intelligence-gathering, and surface-warfare abilities. The testing showed "cohesion between the surface and aviation platforms," the Navy said in a release published on July 9. "The results, lessons learned, and recommendations reported on following this underway test period are absolutely invaluable to the future of the MQ-8C Fire Scout's mission effectiveness and suitability to perform that mission," Lt. Cmdr. Seth Ervin, leader of the Air Test and Evaluation detachment on the Coronado, said in the release. The testing also looked for ways to simultaneously operate both the Fire Scout and a MH-60S Seahawk manned helicopter onboard an LCS, finding that such operations were possible but required extensive planning and coordination. "It has been challenging and rewarding to be one of the first maintainers afforded the opportunity to take both aircraft aboard the ship. Working together, we made the overall product more functional and efficient for the fleet," Aviation Machinist's Mate Second Class Salvatore Greene, a member of the testing squadron, said in the release. The Coronado previously hosted tests of the smaller MQ-8B, which has been used in Afghanistan to detect improvised explosive devices. The larger MQ-8C, which is based on the Bell 407 manned helicopter, retains the hardware and software for the smaller model but has twice the range and can carry a payload three times bigger. The MQ-8C can also fly for 11.5 hours because the redesign for the Fire Scout program fitted the Bell 407's passenger and cargo spaces with fuel tanks, according to Jane's 360. The MQ-8B was to be equipped with a multimode maritime radar and the Advanced Precision Kill Weapon System, consisting of modified 70 mm Hydra rockets fitted with a guidance system. The MQ-8B was limited to three tube launchers, but Capt. Jeff Dodge, the Navy's Fire Scout program manager, told USNI News the service was looking to put seven tubes on the MQ-8C. Limited space aboard the LCS complicates decisions about arming the Fire Scout. The LCS has one magazine that would store all weapons used by aircraft and the ship's own weapon systems. Dodge said in April that the Navy was still deciding how to fit Fire Scout armaments in with the LCS's own weapons. Those complicating factors had effectively put a hold on efforts to arm the MQ-8C until 2023, Dodge said at the time. The MQ-8C can land and takeoff autonomously from any aviation-capable ship and can carry out anti-submarine, anti-surface, mine warfare, and search-and-rescue operations, according to Northrop Grumman. Northrop has also touted the MQ-8C as a range-extender, adding up to 300 miles by providing targeting data for the LCS's over-the-horizon surface missile. The company plans to upgrade the MQ-8C with a new radar and datalink that allow it to send air-to-air and surface targeting information to surface ships. The MQ-8C did its first ship-based flight in December 2014 on the USS Jason Dunham, an Arleigh Burke-class destroyer. It also did underway-testing aboard the littoral combat ship USS Montgomery in April 2017, when it took its first flight from an LCS. Initial operational testing and evaluation for the MQ-8C began on April 16. Pierside testing focused on maintenance and cyber capabilities will continue on the Coronado through mid-July, the Navy said. Initial operational capability is expected by the end of this year. The Navy hopes to have the MQ-8C aboard the LCS fleet by the early 2020s. http://www.businessinsider.com/navy-mq-8c-fire-scout-unmanned-helicopter-passes-test-to-work-with-lcs-2018-7
