The U.S.S. Montauk was an ironclad Moniter of the American Civil War, built in Greenpoint Brooklyn and launched October 1962, decommissioned in Philadelphia in 1965.
Following the war, the Montauk was moved to Washington, and was the site of the autopsy of assassin John Wilkes Booth, as well as a prison for six of his accomplices.
The ship remained in Philadelphia until it was sold in 1904.
