AACS Air Traffic Control - Japan

The Airways and Air Communications Service (AACS) Air Traffic Control unit in Japan traces its roots to the post-World War II occupation period, when American forces established robust air communication and control networks across the region. The AACS was responsible for managing and coordinating air traffic operations, ensuring the safe passage of military and allied aircraft throughout Japanese airspace. During the Korean War, their role became even more vital, providing critical support for air operations and logistics. The legacy of the AACS in Japan laid the foundation for modern U.S. Air Force air traffic control operations in the Pacific, emphasizing safety, efficiency, and international cooperation.
