The Charleston Air Force Base and the Naval Weapons Station at Goose Creek will become one military "team" this morning when the two are formally joined under the operational title of Joint Base Charleston.

Once combined, Joint Base Charleston will employ roughly 21,790 military, civilian and contractor personnel. The installation will encompass 23,777 acres, covering 37 square miles. In all, there will be 16 miles of shoreline, 38 miles of rail, three miles of runways, 56 C-17s and 53 tenant organizations.

The joint basing concept was born out of the Base Closure and Realignment Commission's 2005 recommendations in which local missions are combined to avoid duplication and increase efficiency.

U.S. Sen. Lindsey Graham and U.S. Rep. Henry Brown are scheduled to be guest speakers during today's ceremony. An open house for the public is scheduled to start at 11 a.m. at the Redbank Club on the Naval Weapons Station grounds.

Air Force Col. Martha Meeker is the Joint Base Charleston commander, and Navy Capt. Ralph Ward is the Joint Base Charleston deputy commander.
