Which command is responsible for providing air power to maintain a free and open Indo-Pacific region?

The Pacific Air Forces Command (PACAF) is the correct answer because it is specifically tasked with ensuring air power is available to maintain security and stability in the Indo-Pacific region. PACAF operates and manages U.S. Air Force capabilities across the Pacific, engaging in operations, training, and partnerships with allied nations to promote a free and open environment. Its focus includes deterrence, response to crises, and strengthening regional alliances, all of which are essential for maintaining air superiority and ensuring the region remains free and open.

In contrast, the other commands have different missions that do not specifically focus on the Indo-Pacific area. For example, Air Mobility Command (AMC) primarily focuses on air transport and logistics support rather than regional security. Air Combat Command (ACC) oversees the operational readiness of combat forces but is not limited to the Pacific region. Air Force Space Command (AFSPC) deals with space operations and satellite communications, which, while important, do not directly provide air power in the traditional sense for maintaining regional security like PACAF does.
