| Editors Note: There are over 200 images submitted on these pages covering the following submarines that were constructed at the Manitowoc Shipbuilding Co, Manitowoc, WI,: SS-265 through SS-274, and SS-361 through SS-380. None of them would have seen the light of day if it were not for the efforts of
Curator, Asst. Director, Bill Thiesen of the Wisconsin Maritime Museum, Manitowoc, Wisconsin, and Larry Bohn, who sent them to NavSource for publication. A special debt of gratitude is owed to these two men and the Wisconsin Maritime Museum, Manitowoc, Wisconsin, home of the Cobia (SS-245) for allowing these photographs to be seen by the lovers of naval history worldwide. |
