USS Oriskany (CV/CVA-34) – nicknamed Mighty O, and occasionally referred to as the O-boat – was one of the few Essex-class aircraft carriers completed after World War II for the United States Navy. The ship was named for the Battle of Oriskany during the Revolutionary War. She operated primarily in the Pacific into the 1970s, earning two battle stars for service in the Korean War, and ten for service in the Vietnam War. In 1966, one of the worst shipboard fires since World War II broke out on Oriskany when a magnesium flare was accidentally ignited; forty-four men died in the fire.
