In military organizations, service culture shapes organizational strategy. In the US Space Force today, four historical traditions rooted in different beliefs, values, and assumptions exist, namely, engineers, operators, integrators, and warfighters. Over four periods in Air Force space operations history, a given tradition dominated, while the others competed for currency. This history has implications for contemporary service culture. Changes in the strategic context can reduce a given tradition's effectiveness, though a waning tradition still influences the organization's behavior through its adherents. Understanding these four traditions will help Space Force leaders as they shape service culture today.
