Norfolk Naval Shipyard and Naval Medical Center, Portsmouth are in Portsmouth. They are two very important and historic bases. The shipyard was created as the Gosport Shipyard on November 1, 1767. It had the county's first dry dock. The name was changed after the American Civil War. Although it is in Portsmouth, the name Norfolk was chosen because there was another U.S. Navy shipyard at Portsmouth, New Hampshire. There are also many smaller bases in Portsmouth.
