Shipbuilding in Milwaukee ?

 As I kid we heard about the submarines built during World War II in Manitowoc.  And my class went on a field trip to tour the USS Cobia (which must have been docked in Milwaukee).  Interestingly the USS Cobia wasn't built in Wisconsin but the ones from Manitowoc were similar.  Here is a snapshot of the USS Cobia docked in Milwaukee:

Here is a page with more info on the USS Cobia in Manitowoc:

But I never knew that any shipbuilding was done in Milwaukee.  Then I saw this photo from the Milwaukee Country Historical Society on face:

The USS Sandusky was built by Froemming Brothers:

Froemming Brothers had their shop on the Kinnickinnic River, the southernmost of the three rivers that come together in Milwaukee.

Here is a web page from the Milwaukee public library showing the launching of the USS Claiborne, a cargo ship built by Froemming Brothers.

Froemming Brothers vanished after the war so there was nothing for a grade schooler to "see" in the 1960s.  But 4 warships, 8 tugboats and 14 cargo ships built - the energy of people during World War II was amazing.
