In 2013, Naval Air Systems Command NAVAIR at the Naval Air Station, Patuxent River, Maryland initiated a research task RT-48 to assess the technical feasibility of creatingleveraging a more holistic Model-Based Systems Engineering MBSE approach to support Mission-based Analysis and Engineering in order to achieve a 25 reduction in development time from that of the traditional large-scale weapon systems. The research need included the evaluation of emerging system design through computer models. The first phase of the effort created a strategy and began collecting and structuring evidence to assess the technical feasibility of moving to a complete model-driven lifecycle. The larger context of the NAVAIR mission seeks a Transformation of Systems Engineering SE through MBSE, where MBSE1 is used in the most general way. A key goal is to leverage virtual designs that integrate with existing systems data and simulations, as well as surrogates at varying levels of refinement and fidelity to support a more continuous approach to systems, Family of Systems FoS, and Systems of Systems SoS analysis of alternative AoA and design refinement. Tradeoffs in this context would consider potentially non-optimal solutions that can close the gaps most rapidly to support the warfighters efforts in averting new or emerging threats. This should allow for proposing solutions to the missioncapability gaps, given both cost and time constraints and tradeoffs, but be significantly faster than using the current process while satisfying critically important safety and airworthiness requirements.
