By the article’s end, you’ll have a clear understanding of which solutions best fit your specific project needs.
1. The Evolution of Systems Engineering in Defense & Aerospace
Systems engineering in defense has transformed dramatically over the past decade. Department of Defense reports indicate that modern fighter aircraft contain over 25 million lines of code and thousands of integrated components – a complexity level virtually impossible to manage with traditional document-based methods.
1.1 From Documents to Models: A Transformative Shift
Before 2010, most defense contractors relied on document-centric approaches. Requirements, specifications, and designs existed as separate documents managed by different teams. When changes occurred (which they inevitably did), ensuring consistency across all documentation became a major challenge.
A 2018 NASA study found that document-based projects experienced 3x more integration issues than model-based ones. The aerospace industry took notice.
Model based systems engineering tools developed as a practical solution to these documentation challenges. Rather than spreading information across disconnected files, MBSE creates interconnected digital models that serve as a central reference point for all stakeholders.
The transition gained significant momentum after the Department of Defense published its Digital Engineering Strategy, which specifically highlighted MBSE as a key technology for modernizing defense acquisition and engineering practices.
Many aerospace firms have since incorporated digital engineering practices across their development cycles, with MBSE forming the backbone of these initiatives.
