USS Sturgeon (SS-187), a Salmon-class submarine, was the second ship of the United States Navy to be named for the sturgeon. Her 1944 sinking of the Japanese troopship Toyama Maru, killing more than 5,000 Japanese, was one of the highest death tolls from the sinking of a single ship in history. Her 1942 sinking of the Montevideo Maru which, unknown to crew on the Sturgeon, was carrying over 1,000 POWs, was the worst maritime disaster in Australian history.
