What system is designed to ensure "global strike" capability within the Air Force's core missions?

The system designed to ensure "global strike" capability within the Air Force's core missions is nuclear deterrence. This strategy emphasizes the ability of the U.S. military to project power and strike an adversary anywhere in the world rapidly, particularly through the use of nuclear weapons. Nuclear deterrence relies on the credible threat of nuclear retaliation to deter potential aggressors from attacking or escalating conflicts.

Nuclear deterrence plays a pivotal role in U.S. military strategy by ensuring that any adversary understands the severe consequences of aggression. This strategy supports the broader concept of global strike by maintaining a ready and reliable arsenal capable of being deployed effectively in a crisis, thus contributing to global stability and deterring not only nuclear threats but also conventional military actions.

Other systems, such as missile defense systems, airborne command centers, and unmanned aerial vehicles, do play important roles in military operations and capabilities; however, they revolve around defensive measures, command and coordination, and specific tactical missions, respectively. These elements support the broader mission but do not encapsulate the overarching goal of global strike in the same manner that nuclear deterrence does.
