Deputy Commandant for Aviation
The Deputy Commandant for Aviation (DCA) is the United States Marine Corps' principle advisor on all aviation matters and is the spokesperson for Marine Corps Aviation programs, requirements, and strategy throughout the Department of the Navy and the Department of Defense. DCA is normally the highest-ranking naval aviator in the Marine Corps and reports directly to the Commandant of the Marine Corps. The role of DCA is an administrative position and has no operational command authority over United States Marine Corps Aviation forces.

DCA tour lengths have varied over the years based on war time requirements and personnel turnover. For the last two decades, typical tour lengths have been approximately three years. The billet is normally held by a lieutenant general. DCA and Headquarters Marine Corps Aviation work out of The Pentagon in Arlington County, Virginia.
