The Monitor's 9-ft propeller and 11 ft of propeller shaft were recovered in June 1998. The propeller was removed from the wreck to help relieve stresses at the stern, and to preserve one of the few existing original John Ericsson screw propellers. Ericsson was the Monitor's designer and an engineering visionary of his time. Image courtesy of Monitor 2001, Jeff Johnston, Monitor Collection, NOAA/OER.
