Analysis on the Collaborative Development of the Space-Oriented US Digital Engineering Ecosystem

Models have been a hot topic for many years. Still, people are paying unprecedented attention to them because digital engineering (DE), which uses models as the “blood,” has become a symbol of the Fourth Industrial Revolution. Space and national defense have already become the pillar fields of technological innovation today. As the two major forces in the space field of the United States, NASA (the National Aeronautics and Space Administration) and USSF (the United States Space Force) have a strong interest in DE with models as the “blood,” and actively seek coordinated development under the digital engineering ecosystem (DEE). This paper focuses on summarizing the practices of NASA and USSF in the field of DE, refining the key points and methods of DE construction in terms of core ideas, fundamental base, cultural base, etc., and forming relevant enlightenment and thinking, to provide a reference for China to carry out the work-related DE.
