Abstract: Aspects of the invention can provide a system and method for evaluating system architectures that can include a system architecture design device that creates a system architecture having at least one system architecture variant, a simulation system that performs multiple warfighting simulations using the system architecture in a same scenario while varying the at least one system architecture variant, and a post processor that evaluates warfighting outcomes of the multiple simulations that correspond to different system architecture variants. Further, the system architecture design component can create the system architecture to include at least one of an intelligence, surveillance, reconnaissance (ISR) and strike architecture, as well as a characteristic of sensors and interceptors that can include at least one of an aerial, space based, sea borne, land based and subterranean device.
