This would be no easy task since the Hunley was submerged 30 feet deep in murky, choppy ocean waters. Divers excavated an area approximately 40 feet wide by feet long to expose the top of the Hunley. Two massive 18 by 12 foot, custom-engineered suction piles typically used in deep water oil rig mooring systems were placed on either side of the submarine to provide a stable platform for the recovery work. A large overhead truss was lowered onto the submarine and attached to the suction piles.
Machines lowered the truss over the wreck site and then divers helped guide it into a level position straddling the Hunley. Divers carefully burrowed small tunnels beneath the submarine, inserting thirty slings one by one and attaching each to the truss. A load cell monitoring device was attached to each sling to alter and monitor weight distribution.
The load cells also sent an alarm in the event weight became unevenly—and dangerously—applied during the recovery process. Each sling was injected with inflatable foam that conformed to the contours of the vessel, creating a safe cradle to lift the Hunley off the ocean floor.
The harbor was filled with on-lookers. Spectators and reporters from around the world lined the docks, watching history unfold. Lift the Hunley — Just as the crew did in on the night they made world history, the recovery team waited for a calm sea for the actual lifting of the Hunley.
The well-planned recovery procedure was completed flawlessly, with the historic artifact raised safely. Support personnel stabilized the submarine with tension straps to keep her safe. She was brought to the Warren Lasch Conservation Center and placed in a 75, gallon steel tank filled with chilled, fresh water to help protect and stabilize the submarine.
The lab facility was specifically designed to excavate and conserve the vessel. Now that the Hunley was safe, the work of learning her secrets could begin. They were removed from the submarine and plans were immediately put in place to give them a proper burial, an event that had been impossible for over a century. A ground breaking effort began to retrieve the fragile submarine from the sea.
She was then delivered to the Warren Lasch Conservation Center, a high-tech lab specifically designed to conserve the vessel and unlock the mystery of her disappearance. The Hunley has since been excavated and proved to be a time capsule, holding a wide array of artifacts that can teach us about life during the American Civil War.
The submarine and the hundreds of artifacts found onboard are currently undergoing preservation work while archaeologists use the historical clues they have found to piece together the final moments of the Hunley and her crew.

Hunley became the first successful combat submarine in world history when eight men entered an experimental vessel with a mission to sink the USS Housatonic. The Hunley successfully rammed her spar torpedo into the hull of the Housatonic, causing the warship to sink within minutes.
After completing this momentous feat, the Hunley crew signaled their success to shore but then never returned home. That night, history was made. At the same moment, a mystery was born. The Hunley became the first submarine ever to sink an enemy ship.
But why had she suddenly disappeared? What caused her to sink? And would she ever be found? After being lost at sea for over years, the Hunley was located in and raised on August 8, The submarine was brought to the Warren Lasch Conservation Center in Charleston, South Carolina where scientists continue to work to unlock the mysteries of the Hunley.
