Naval Ordnance Station Louisville ("NOSL") is a major employer of Louisville, Kentucky, near Muhammad Ali International Airport. For over fifty years, starting in late 1941, it provided maintenance and equipment for the United States Navy. Since the end of the Cold War, Naval Ordnance was the main hub for repair and replacement of major guns and equipment on battleships, along with work for NASA. By the mid-1990s, most of it was turned over to private companies. The complex is currently named the Greater Louisville Technology Park.
