USS "Great Sitkin" (AE-17) was a "Mount Hood" class ammunition ship, which served in the United States Navy from 1945 to 1973. USS "Great Sitkin" supported USN operations in several major theatres, including the Mediterranean, the Atlantic, Cuban Missile Blockade, Guantanamo Bay, and the Vietnam War. In the tradition of naming ammunition ships after volcanos, AE-17 was named after the Great Sitkin Volcano in Alaska.
