The 41st Air Division was organized, administered, equipped, and trained assigned units in Japan from March 1952 – January 1968,. It conducted combined planning with the Japan Air Self Defense Force and, when directed by higher headquarters, joint and combined training with other allied forces. It also developed tactics and examined technical aspects of aerial warfare requirements for new weapons and weapon systems, and improved uses of current weapons. In addition, its assigned units carried out aerial surveillance and reconnaissance missions and collected, evaluated, produced and disseminated intelligence data. The division maintained operational control of all United States Navy and United States Marine Corps defense type aircraft, United States Army antiaircraft artillery, and surface to air missile units in Japan. In 1962 it became an operational organization that controlled, evaluated, and exercised assigned units. In fulfilling this role the division participated in exercises such as Commando Night, Commando Rock, Bright Night and Teamwork. In response to the Gulf of Tonkin Incident in 1964, the 41st deployed personnel and aircraft to Southeast Asia. These deployments continued periodically until the unit was inactivated.
