Prairie du Sac (Sauk Prairie) was selected as "Aircraft Carrier Town USA" by the Aircraft Carrier Industrial Base Coalition (ACIBC), which represents the more than 2,000 businesses from 46 states that supply parts, equipment and services for the construction and maintenance of U.S. Navy aircraft carriers.
 
In Milwaukee Valve’s Prairie du Sac facility, every valve that the company builds for the U.S. Navy is cast, machined, assembled and tested prior to delivery. To appreciate the scale of the operation, Milwaukee Valves can be found on every U.S. Navy vessel built since 1964.
