The Naval Air Warfare Center Training Systems Division (NAWCTSD) is an Echelon IV command of the United States Navy, reporting to the Commander, Naval Air Warfare Center - Aircraft Division (NAWCAD) at NAS Patuxent River, Maryland. NAWCTSD is located in Orlando, Florida in the Central Florida Research Park, adjacent to the University of Central Florida (UCF). The facility is a part of a larger military installation within the Central Florida Research Park known as Naval Support Activity Orlando (NSA Orlando).

The Commanding Officer (CO) of NAWCTSD, an aeronautically designated U.S. Navy Captain, is also dual-hatted as the installation CO of NSA Orlando. This results in a dual-track command chain, answering to the Commander of NAWCAD as CO of NAWCTSD for Naval Air Systems Command (NAVAIR) issues, and to the Commander, Navy Installations Command (CNIC) as CO of NSA Orlando for installation-related issues.

NAWCTSD is the principal U.S. Navy center for research, development, test and evaluation, acquisition, life cycle program management and product support of all aviation, surface and subsurface training systems, devices and programs for the U.S. Navy and all aviation training systems for the U.S. Marine Corps. It also provides interservice coordination and training systems support for the U.S. Army, U.S. Air Force and U.S. Coast Guard.
