In 1966, the four Navy
materiel bureaus were disestablished and replaced with six systems commands: •
Bureau of Yards and Docks was replaced with Naval Facilities Engineering Command (NAVFAC) •
Bureau of Supplies and Accounts was replaced with Naval Supply Systems Command (NAVSUP) •
Bureau of Naval Weapons was replaced with Naval Ordnance Systems Command (NAVORD) and Naval Air Systems Command (NAVAIR) •
Bureau of Ships was replaced with Naval Ship Systems Command (NAVSHIPS) and Naval Electronic Systems Command (NAVELEX) In 1985, Naval Material Command was disestablished, placing the systems commands directly under the
chief of naval operations; an Office of Naval Acquisition Support was established to create acquisition support for functions that spanned across Commands, and which required a degree of independence in their operations. At the same time, NAVELEX became Space and Naval Warfare Systems Command (SPAWAR), expanding its traditional
command, control, and communications focus into undersea surveillance and space systems. In 2019, SPAWAR was renamed to Naval Information Warfare Systems Command (NAVWAR). Marine Corps Research, Development and Acquisition Command (MCRDAC) was established in 1987, and in 1992 it changed its name to Marine Corps Systems Command (MCSC). In the 1990s it picked up several programs from
Headquarters Marine Corps as well as the
Assault Amphibious Vehicle program from NAVSEA. ==See also==
