A MATTER OF COURSE


2023 Association of the U.S. Army annual meeting. “We must continue to embrace innovation and transformation or risk fail- ing to address future threats,” Wormuth said at the October event in Washington. “In close partnership with industry, the Army has pressed ahead and stayed on track to implement our most ambitious modernization effort in 40 years. With the introduction of each new system, we continue to increase our force’s capabil- ity to respond to various threats and serve as a credible deterrent to our adversaries.”


WHAT IS DIGITAL ENGINEERING? Defense Acquisition University defines digital engineering as “an integrated digi- tal approach that uses authoritative sources of systems’ data and models as a contin- uum across disciplines to support life cycle activities from concept through disposal.” Te beginning of the digital engineering effort for combat vehicles can be traced back to 2021, when the Army placed five


companies under contract to develop digital designs of the XM30, a combat vehicle that will replace the M2 Brad- ley in armored brigade combat teams. Te XM30 was previously known as the Optionally Manned Fighting Vehicle.


Te digital design process has allowed the Army to save time and cost while develop- ing design solutions for the future armored vehicle.


Five digital designs were analyzed and evaluated by the Army against the require- ments detailed in the acquisition process


and managed with a product life cycle management (PLM) tool. Te PLM tool serves as the product’s authoritative source of truth—a single centralized model to avoid issues of version control that often develop with a document-based approach. Te PLM allows the Army to map high- level requirements, from broad-based concepts such as mobility and lethality, to more focused details, such as the tests and evaluations that will prove whether the product meets the capabilities outlined in the Capability Development Docu- ment (CDD).


“We are maximizing the best, most modern tools available to us to ensure that the vehicle that we deliver will be the best.”


According to DOD’s Digital Engineering Strategy, “Te goal [of the authoritative source of truth] is to enable delivery of the right data to the right person for the right use at the right time.”


Norman stressed that imperative as the Army looks to the future of combat vehi- cles. “We are committed to using the right tools and to building the best teams to drive these new capabilities into our formations,” he said.

Previously, when the Army designed combat vehicles and other major systems, an analog or paper process was used. Tis document-based approach is expensive and error-prone. Costs increase as arti- facts become inconsistent and assumptions change faster than the document approval process can support. Tis created problems
