USS Oriskany (CV-34)

USS Oriskany (CV-34)

USS Oriskany (CV/CVA-34) – nicknamed Mighty O, The O-boat, and Toasted O – was one of 24 Essex-class aircraft carriers completed during or shortly after World War II for the United States Navy. The ship was the third US Navy ship to bear the name, and was named for the Revolutionary War Battle of Oriskany.

The history of Oriskany differs considerably from that of her sister ships. Originally designed as a "long-hulled" Essex-class ship (considered by some authorities to be a separate class, the Ticonderoga class) her construction was suspended in 1947. She eventually was commissioned in 1950 after conversion to an updated design called SCB-27 or "27-Charlie", which became the template for modernization of 14 other Essex-class ships.

She operated primarily in the Pacific into the 1970s, earning two battle stars for service in the Korean War, and five 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.

Oriskany's post-service history also differs considerably from that of her sister ships. Decommissioned in 1976, she was sold for scrap in 1995, but was repossessed in 1997 because nothing was being done (lack of progress). In 2004 it was decided to sink her as an artificial reef off the coast of Florida in the Gulf of Mexico. After much environmental review and remediation to remove toxic substances, she was carefully sunk in May 2006, settling in an upright position at a depth accessible to recreational divers. As of 2008 the Oriskany is "the largest vessel ever sunk to make a reef".
