USS Slater is a Cannon-class destroyer escort that served in the United States Navy and later in the Hellenic Navy. The ship was named for Frank O. Slater of Alabama, a sailor killed on the cruiser USS San Francisco during the Naval Battle of Guadalcanal. He was posthumously awarded the Navy Cross for gallantry in action and the Purple Heart. Following service during World War II, the ship was transferred to Greece and renamed Aetos. Decommissioned in 1991, the destroyer escort was returned to the United States.
USS Slater is now a museum ship on the Hudson River in Albany, New York, the only one of its kind afloat in the United States. Slater was designated a National Historic Landmark on 2 March 2012.
