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.

By Shane Harris The Army has chosen Palantir Technologies to deploy a complex battlefield intelligence system for soldiers, according to Army documents, a significant boost for a company that has attracted a devoted following in national security circles but had struggled to win a major defense contract. Industry experts said it marked the first time that the government had tapped a Silicon Valley software company, as opposed to a traditional military contractor, to lead a defense program of record, which has a dedicated line of funding from Congress. The contract is potentially worth more than $800 million. The Army's decision to go with Palantir, which was co-founded by Peter Thiel, the billionaire investor and sometimes adviser to President Trump, brings to a close the latest chapter in a fierce competition. In March 2018, the Army chose Palantir and Raytheon to vie for the next phase of the Distributed Common Ground System (or DCGS-A, for Army), which lets users gather and analyze information about enemy movements, terrain and weather to create detailed maps and reports in real-time. The system is designed to be used by soldiers fighting in remote, harsh environments. But critics within the Army and in Congress have for years complained that DCGS-A cost too much and didn't deliver the intelligence and capabilities that soldiers needed. Some soldiers said the system was too hard to use and searched for alternatives. Many became backers of Palantir, which sells to governments and businesses, including in the financial and health care sectors. Palantir and its advocates argued that their software was cheaper and could meet all the Army's requirements. But Army brass defended their decision to pay for a custom-built platform. In 2016, Palantir successfully argued in court that the government was required by law to consider purchasing commercial products, when available, rather than custom ones. That sent the Army back to the drawing board and led to the face off between Palantir and Raytheon. Before his death. Sen. John McCain (R-Ariz.) praised the new approach on Twitter, noting that after the Army had already spent $3 billion in development costs, “it was time to find another way.” Raytheon and Palantir were allowed to test their respective software platforms with a live audience of soldiers, who told them what they liked and didn't and what they would change. The two companies then refined their offerings to suit the Army's needs. Traditionally, the government first chooses a company to build a system according to a set of detailed requirements. But this approach let the Army take both companies' products for a test drive before settling on the winner. “The Army changed its approach to acquisition,” Doug Philippone, a former Army Ranger who leads Palantir's defense business, said in an interview. He said the company was always confident it could win if it were allowed to adjust its technology after getting feedback from soldiers, who he said put the software through a rigorous test, even parachuting out of airplanes with reinforced laptops containing Palantir's software. Chris Johnson, a spokesman for Raytheon, said the company was disappointed in the outcome. “We will wait for the Army's de-brief to understand their decision.” The Army did not provide a comment for this story. Raytheon and Palantir may compete for subsequent phases of work on the program. Unlike most Silicon Valley start-ups, which aim to make their fortunes building consumer applications and software, Palantir at its founding set its sites on Washington, believing that its data analytics tools would find an eager market among U.S. spy agencies and the military, which are constantly trying to manage ever-expanding streams of information. Philippone said the Army win had validated Palantir's strategy. “We founded the company around solving this particular mission,” he said. The company faced initial skepticism from investors, who thought it couldn't overcome entrenched bureaucratic interests and what they saw as political favoritism that led the Pentagon to spend billions every year with the same small group of Beltway contractors. “Everyone told us we should stay away from Washington because it was corrupt and we didn't know how to play golf with senators,” Joe Lonsdale, a Palantir co-founder, said in a 2011 interview. The company got an early investment in 2005 from In-Q-Tel, the CIA's venture capital arm, which tries to quickly develop technologies that the intelligence agency might use. The In-Q-Tel connection helped Palantir get meetings with U.S. officials and intelligence analysts, and even test its software with the CIA's counterterrorism center, according to people familiar with the matter. https://www.washingtonpost.com/world/national-security/palantir-wins-competition-to-build-army-intelligence-system/2019/03/26/c6d62bf0-3927-11e9-aaae-69364b2ed137_story.html

By: The Associated Press SAN FRANCISCO — Google won't renew a contract with the Pentagon that provides the company's artificially intelligent algorithms to interpret video images and improve the targeting of drone strikes. That's according to reports in Gizmodo, Buzzfeed, and The New York Times Friday. The reports said Google Cloud business head Diane Greene told employees of the decision not to renew the 18-month deal past the end of 2019, when the current contract ends. Google representatives did not respond to a request for comment. The so-called Project Maven had riled Google employees, including several who quit and thousands of others who signed a petition asking CEO Sundar Pichai to cancel the project and enact a policy renouncing the use of Google technology in warfare. https://www.c4isrnet.com/news/pentagon-congress/2018/06/03/reports-google-wont-renew-pentagon-contract-to-use-ai/
