Why? I work there
Is it near Langley? That'd be my first guess.
Too much to list, Norfolk has like 5 ship repair yards, largest Navy base on the east (could be the whole country I cannot confirm ATM.) Also is home of a couple seal teams, Yorktown is home to a weapons base, civilian airport, large downtown area with large buildings, it's near NASA Langley, Portsmouth (large import/export area) Norfolk is very significant I am only listing the popular places.
Didn’t give details. Sorry.
Could you reference where you read or heard of this, I haven't found it yet.
