By Chief Journalist Milinda D. The ex-USS Oriskany (CVA 34), the last Essex-class aircraft carrier in the fleet’s inactive ship inventory, served the Navy for more then 25 years, maintaining a powerful presence during the Korean War and the Vietnam conflict. Decommissioned September 1976, the ship is ready to do more sea time, only this time beneath the surface, serving as an artificial reef. “Artificial reefing benefits the economical environment of the respective state receiving the ship by relieving stress on the natural reef,” said Capt. Lawrence M. Jones Jr., program manager for the Inactive Ships Program Office, Naval Sea Systems Command (NAVSEA).
