Step-by-step explanation:
The primary mission of providing the joint force air component commander (JFACC) with the necessary tools to fight and win a major theater war within the scope and coordination of all land, sea, and air forces falls under the responsibility of the United States Air Force. The U.S. Air Force oversees the many elements of the U.S. armed forces, including the Army, Navy, Marine Corps, and Air Force.
The U.S. Air Force plays a crucial role in providing air support, intelligence, surveillance, and reconnaissance capabilities to the JFACC. They are responsible for maintaining a fleet of aircraft, developing strategies, and coordinating with other military branches to ensure successful joint operations.
For example, during World War II, the U.S. Air Force played a vital role in establishing and operating island-based airfields in the Pacific theater. These airfields provided strategic advantages and helped facilitate the eventual ground invasion of Japan.
