USS Caesar (AC-16) was a collier that was built in England in 1896 and scrapped in Japan in 1935. She was launched as Kingtor for a British shipping company, served in the United States Navy as Caesar from 1898 to 1923, and then was sold to a Canadian shipping company who renamed her Mogul.

USS Dewey (YFD-1) was a floating dry dock built for the United States Navy in 1905, and named for American Admiral George Dewey. The auxiliary floating drydock was towed to her station in the Philippines in 1906 and remained there until scuttled by American forces in 1942, to prevent her falling into the hands of the invading Japanese.
