NAVFAC

The Naval Facilities Engineering Command (NAVFAC) is the United States Navy's engineering command, committed to the Navy's and United States Marine Corps' combat readiness. NAVFAC is headquartered at the Washington Navy Yard and is under the command of the Chief of Civil Engineers, as of 4 November 2015^[update], RADM Bret J. Muilenburg.

The Naval Facilities Engineering Command is the oldest of the Navy's system commands, having been established as the Bureau of Yards and Docks in August 1842. Its officers comprise the Navy Civil Engineer Corps, which was formed in March 1867. During the 1966 reorganization of the Department of the Navy, the Bureau of Yards and Docks became the Naval Facilities Engineering Command.

NAVFAC is headquartered in Washington, D.C. and is made of 13 component commands; 9 are Facilities Engineering Commands that report to either NAVFAC Atlantic or NAVFAC Pacific.

There are also two specialty commands, Navy Crane Center (NCC) at the Norfolk Naval Shipyard in Portsmouth, Virginia and Naval Facilities Engineering and Expeditionary Warfare Center (EXWC) in Port Hueneme, California.

On August 31, 1842, the Bureau of Navy Yards and Docks (BuDocks) was established, the forerunner to the Naval Facilities Engineering Command.
