The Mahan-class destroyers served in the United States Navy before and during World War II. The lead ship of the class was named for Alfred T. Mahan, a US Naval officer and influential theorist on sea power.
The 18 ships were built by various shipyards between 1935 and 1937. The last two ships, USS Dunlap and USS Fanning were modified slightly and sometimes referred to as the Dunlap class. The Mahans were the second and most numerous of the six classes of 1500-ton pre-war destroyers that modernized the United States Navy.
Six of the ships were combat losses during World War II, and two were expended in post-war atomic bomb tests. The remainder were deactivated and scrapped shortly after the end of the war.
The spectacular explosion of the forward magazine of USS Shaw provided one of the most iconic photographs of the Attack on Pearl Harbor.
The fictional Mahan-class destroyer USS Keeling is the setting for C.S. Forester's novel The Good Shepherd.
