What overall objective should be included in the JFACC's mission statement related to air operations?

The mission statement of the Joint Forces Air Component Commander (JFACC) must emphasize gaining air superiority in the Joint Operations Area (JOA) because air superiority is a critical prerequisite for successful joint operations. Air superiority ensures that friendly forces can operate effectively in the airspace without significant interference from enemy air forces. It allows for freedom of movement for ground and naval operations and facilitates the effective delivery of air support to ground troops.

Furthermore, gaining air superiority can significantly impact the outcome of military engagement by denying the adversary the ability to use their air power effectively, thereby enhancing the safety and success of friendly forces. This focus aligns with the JFACC's role, which entails directing air operations to achieve the joint force commander's objectives, with air superiority being a fundamental aspect of those operations.

The other options, while relevant to some aspects of military operations, do not encapsulate the overarching goal of air operations in the same way. Sustaining a defense posture and engaging in ground combat are more limited in scope, and conducting peacekeeping operations, while important, does not specifically address the military focus on gaining an advantage in airspace, which is vital for broader operational success.
