USS Bullhead (SS-332), a Balao-class submarine, was the very last US Navy ship sunk by enemy action during World War II, probably on the same day that the first atomic bomb was dropped on Hiroshima. She was the only ship of the United States Navy to be named for the bullhead (any large-headed fish, especially the catfish, miller's thumb, and sculpin). Her keel was laid down by the Electric Boat Company of Groton, Connecticut. She was launched on 16 July 1944 sponsored by Mrs. Howard R. Doyle, and commissioned 4 December 1944 with Commander W. T. Griffith in command.
