We took a quick loop around the 'USNS American Mariner' in Chesapeake Bay.
In October 1966, she was scuttled in shallow water with demolition charges by Navy Underwater Demolition Team #22. Settling upright in 20 feet (6.1 meters) of water, she appears to be merely anchored there. The hulk was used for target practice by naval aviators flying out of Naval Air Station Patuxent River, Maryland, until at least 1971. Her hulk is still visible in the Chesapeake Bay, at 38°02′25″N 76°09′17″W, roughly midway between Point Lookout and Smith Island.
