Digital Twin Consortium releases report: Aerospace & Defense: Bridging the Gap for a Secure, Interoperable Future
In the high-stakes realm of aerospace and defense, where precision and reliability are paramount, the Digital Twin Consortium released a new paper about how digital twins have emerged as a transformative technology. These virtual replicas of physical assets—spanning fighter jets to entire manufacturing ecosystems—hold immense potential to reshape how the Department of Defense (DoD) designs, tests, and sustains its systems. However, a comprehensive white paper from the Digital Twin Consortium (DTC), published on April 15, 2025, titled Aerospace-Defense Digital Twin Research and Technology Gap Analysis, reveals significant obstacles to realizing this potential. The paper outlines critical challenges and proposes a roadmap for an industry poised at a technological inflection point.
Digital Twin Consortium: The Promise of Digital Twins in Aerospace
Digital twins, born from NASA’s efforts to simulate space systems, are dynamic, data-driven representations that evolve in tandem with their physical counterparts, providing potential insights into performance, maintenance, and operational readiness. For the DoD, faster innovation cycles, cost-efficient maintenance, and enhanced mission effectiveness are key anticipated benefits according to Digital Twin Consortium (DTC) research and DoD strategy documents. As David Shaw, Co-Chair of the Digital Twin Consortium Aerospace & Defense Working Group, states, “All Department of Defense branches are developing and deploying digital transformation strategies. These strategies include digital twins and rely on established standards to govern their development.”
The DoD’s 2021 Digital Building Code memorandum, alongside strategies from the Navy, Army, and Space Force, underscores a unified commitment to digital engineering ecosystems. These initiatives position digital twins as intended enablers of agile development, seamless collaboration, and predictive analytics across the product lifecycle—from design to decommissioning.
The Standardization Conundrum
A central issue highlighted by the Digital Twin Consortium is the lack of harmonized standards. The white paper defines a “standard gap” as the absence of governance needed to shift from document-based to model-based environments. Without clear standards, stakeholders encounter incompatibilities in 3D engineering models, software frameworks, and data exchanges across suppliers, integrators, and customers. This fragmentation impedes the DoD’s vision of a Joint All-Domain Operations (JADO) ecosystem, where interoperability is essential.
The Digital Twin Consortium recognizes the challenge is particularly pronounced in contracting. As the white paper notes, “Often, the maturity of the digital twin requirement and intended capability of the digital twin model(s) required throughout the lifecycle are not fully understood during the acquisition process.” This results in misaligned expectations and risks, such as unclear success criteria for a digital twin’s operational use or inconsistent data interoperability. The Digital Twin Consortium advocates for a cross-functional focus on standards to guide stakeholders, ensuring engineering data is harmonized at a contractually defined maturity level.
System of Systems: Complexity Amplified
The complexity escalates when digital twins are applied to Systems of Systems (SoS)—interconnected networks like air traffic control or multi-domain military operations. SoS digital twins must simulate the behavior of multiple interacting systems, each with distinct data formats, communication protocols, and operational constraints. The white paper identifies numerous challenges, including computational demands, cybersecurity vulnerabilities, and significant governance challenges, particularly around data ownership and interoperability.
Integrating legacy systems further complicates matters. Many DoD assets rely on decades-old technology not designed for digital twin integration. The Digital Twin Consortium observes, “Different systems within an SoS often use different communication protocols or data formats, making it challenging to integrate these systems.” To address this, the Digital Twin Consortium proposes conceptual tools, including a “periodic table” for SoS digital twins to enhance collaboration and interoperability.
Cybersecurity: The Achilles’ Heel
Digital twins’ deep integration with physical systems—through sensors, IoT devices, and real-time data streams—introduces significant risks. As the Digital Twin Consortium emphasizes, “cybersecurity needs to be baked into the digital twin from the onset.” A security breach in a digital twin may pose risks that could lead to operational disruptions or safety issues, as noted by cybersecurity researchers. Key measures include multi-factor authentication, data encryption, and zero-trust architectures.
The white paper outlines unique challenges, such as the complexity of securing data from diverse sources and vulnerabilities in the supply chain. “Digital twin ecosystems involve a chain of hardware, software, and services providers, each potentially introducing security risks,” the authors caution. Compliance with frameworks like the DoD’s Cybersecurity Maturity Model Certification (CMMC) is essential, though inconsistent adoption among industry partners remains a concern.
AI and the Rise of Intelligent Digital Twins
Artificial intelligence (AI) is being explored to elevate digital twins from static models to dynamic systems capable of advanced decision-making. As defined by the Digital Twin Consortium, an intelligent digital twin is envisioned to “observe and perceive information from the environment, analyze it using models, reason, and take action.” This capability could transform applications like predictive maintenance, where AI-driven twins are in development to anticipate failures, or mission simulations, where they adapt to novel scenarios.
However, AI introduces challenges, notably the lack of interpretability in its decisions, which can undermine trust in defense applications. The Digital Twin Consortium calls for frameworks to enhance transparency and define human-digital twin interactions. In related expert commentary, Bernard Marr envisions a future where integrating AI with 3D simulation environments and natural language services could create “a predictive 3D environment to view what will happen next in real-time,” though such capabilities remain aspirational.
The Digital Thread: Unifying the Ecosystem
A robust digital thread—the seamless flow of data across a system’s lifecycle—is critical for effective digital twins. Yet, the Digital Twin Consortium finds that much of the data driving aerospace systems is trapped in non-standardized formats. Many tools used across the lifecycle, such as Excel or SysML-based tools, face interoperability issues when not integrated within standardized pipelines. The white paper notes, “The term digital thread is often used as a buzzword without much detail about what actually constitutes a digital thread.”
The Digital Twin Consortium proposes a reference architecture and maturity model for digital threads, potentially leveraging tools like Syndeia or eQube, which are commonly referenced in the ecosystem, to enhance interoperability. Such a framework would clarify the components of a robust digital thread, enabling stakeholders to trust and utilize data across the ecosystem.
DoD 5000.97: A Blueprint for Progress
The DoD’s Instruction 5000.97, Digital Engineering, encourages adoption of authoritative and lifecycle-relevant data sources, open standards like ISO 10303 (STEP), and lifecycle data management to ensure digital twins are interoperable and secure. Aligned with the DoD Data Strategy, it emphasizes metadata tagging and data accessibility to support twin accuracy. Brian Schmidt, a white paper author, underscores, “The digital twins in the DoD ecosystem are vital for weapon systems, logistics, maintenance, and readiness.”
Despite this guidance, adoption is uneven. Legacy systems, data silos, and inconsistent standards across agencies pose challenges. The Digital Twin Consortium highlights opportunities to leverage DoD 5000.97 for AI-driven predictions, optimized condition-based maintenance, and accelerated R&D for next-generation systems.
A Call to Action
The Digital Twin Consortium’s white paper serves as an urgent call for the aerospace and defense industry to address these challenges. Its seven recommendations—from standardizing governance to automating model calibration—provide a roadmap for realizing the transformative potential of digital twins. By prioritizing interoperability, cybersecurity, and intelligent automation, the DoD aims to unlock efficiencies that may reduce lifecycle costs and enhance mission readiness, as projected by current Digital Twin Consortium findings.
Collaboration will be critical. The Digital Twin Consortium’s vision of a standardized, secure, and AI-enhanced digital twin ecosystem is a strategic necessity for an industry where every system and second counts. The path forward demands action now to bridge these gaps and secure a future where digital twins deliver on their promise.
