Charleston Naval Shipyard (formerly known as the Charleston Navy Yard) was a U.S. Navy ship building and repair facility located along the west bank of the Cooper River, in North Charleston, South Carolina and part of Naval Base Charleston. It began operations in 1901 as a drydock, and continued as a navy facility until 1996 when it ceased operations as the result of recommendations of the 1993 Base Realignment and Closure Commission. At that time it was leased to Detyens Shipyards, Inc.
