What was one major reason for the establishment of the Department of the Air Force?

The establishment of the Department of the Air Force was primarily aimed at developing specialized airpower. This recognition stemmed from the increasing importance of air operations in modern warfare and the need for a dedicated branch that could focus exclusively on aerial capabilities. By formalizing the Air Force as a separate branch, the U.S. government acknowledged the strategic significance of airpower in achieving national military objectives.

This decision allowed for the prioritization of aerial tactics, technology, and training, ensuring that the Air Force could effectively operate aircraft and conduct missions that were critical to U.S. defense strategies. With the establishment of a separate department, resources could be allocated specifically toward air operations, fostering advancements in aviation and aerospace technologies that would ultimately enhance military effectiveness.

In contrast, the other options do not align with the primary objectives that led to the formation of the Department of the Air Force. Enhancing naval aviation capabilities relates more to the Navy's domain, while consolidating all military branches and increasing ground forces efficiency do not reflect the strategic shift towards recognizing airpower as a distinct and vital military capability.
