The concluding Ceremony in New York
The Spencer's last voyage would be from Governors Island New York to Curtis Bay Maryland.

She was decommissioned on 23 January 1974 and then served as an "Engineer Training School" where students trained using her steam propulsion plant until 15 December 1980.  The Spencer was then sold for $27,955 on 8 October 1981 to the North American Smelting Company of Wilmington, Delaware, and scrapped.

Through the consorted efforts of association members the ship's mast and bell were saved from being scrapped. They would later be erected in New York at the pier for the USS Intrepid.
