Design of complex systems such as a manned-unmanned team of aircraft must include safety considerations in the earliest stages of the system development process. This paper considers a team of one manned aircraft with two or more unmanned support aircraft as a systems of systems analysis problem. Initial exploration of the systems of systems goals, constraints, and requirements are organized in an intent specification. Then a Systems- Theoretic Accident Model and Processes methodology is used to identify accidents, hazards, and safety constraints as well as to develop a set of control structure block diagrams of the manned-unmanned team system. Systems-Theoretic Process Analysis is used to identify unsafe control actions. The system is modeled in the Architecture Analysis and Design Language to include the accidents and hazards identified as a baseline for formal analysis.
