United States Navy systems commands

The systems commands, abbreviated as SysCom or SYSCOM, are the materiel agencies of the United States Department of the Navy, responsible for the design, construction, and maintenance of military systems such as ships, aircraft, facilities, and weapons. The systems commands replaced the Navy bureau system in 1966 and report to the Assistant Secretary of the Navy for Research, Development and Acquisition.^[1] The current Navy systems commands are:

• Naval Sea Systems Command (NAVSEA)
• Naval Air Systems Command (NAVAIR)
• Naval Information Warfare Systems Command (NAVWAR) (formerly SPAWAR),
• Naval Facilities Engineering Systems Command (NAVFAC)
• Naval Supply Systems Command (NAVSUP)
• Marine Corps Systems Command (MCSC)

The Office of Naval Research is sometimes grouped with the systems commands, although it has a different mission geared towards scientific research rather than weapon systems development and acquisition.^[2]
