The film follows a demolition team's mission to sink the USS Oriskany, a 900-foot long aircraft carrier, the most complex and best built ship in naval warfare, and to create the largest artificial reef in the world.
Battling through four-inch-thick steel plating and hazardous waste, the team discovers the secret of sinking an aircraft carrier, and in the process, writes a new chapter in marine demolition.
The USS Oriskany was built not to sink, but to withstand missiles and bomb hits during a war. She operated primarily in the Pacific into the 1970s, in both the Korean War, and the Vietnam War.
The courageous demolition team must go through tight tunnels throughout the ship, making sure everything is removed that could be harmful to the environment, meeting all safety codes.
