On the evening of February 17, 1864, the H. L. Hunley became the world's first successful combat submarine by sinking the USS Housatonic.
After signaling to shore that the mission had been accomplished, the submarine and her crew of eight mysteriously vanished.
Lost at sea for over a century, the Hunley was located in 1995 by Clive Cussler's National Underwater and Marine Agency (NUMA).
The innovative hand-cranked vessel was raised in 2000 and delivered to the Warren Lasch Conservation Center, where an international team of scientists are at work to conserve the submarine for future generations and piece together clues to solve the mystery of her disappearance.
The Hunley Project is conducted through a partnership with the Clemson University Restoration Institute, South Carolina Hunley Commission, Naval Historical Center, and Friends of the Hunley.
