Digital Engineering practices and ecosystem capabilities [1] optimize designs by providing digital solutions with end-to-end information flows that are consistent from concept development, through test and experimentation, all the way to fully defined capabilities influencing systems across Ground Vehicle Brigade Combat Teams (GVBCT). This approach delivers: 1) improved development, demonstration, and assessment of autonomous vehicle capabilities, technologies, software, algorithms, controls, and performance; 2) a plug and play (PnP) interface for system-of-system and vehicle platform mission thread analysis and interoperability; and 3) 3D gaming technology to support advanced virtual scene generation and world model. The modernization of laboratory facilities to meet research and development (R&D) needs, support advanced technology development, and improved vehicle prototypes. The Brigade Level Integration Laboratory (BLIL) architecture provides a set of views composed using Systems Modeling Language (SysML) and governed by agreed-upon Architecture Viewpoints in accordance with IEEE 42010-20113]. This model-based architecture elaborates on the problem and solutions domains for the BLIL encompassing its requirements, structure, behavior, and constraints with full relational tracing between system elements in SysML to demonstrate that the architecture satisfies all BLIL requirements.
