After gathering support, funding, and technical capability, the American Civil War Submarine H. L. Hunley (1863-1864) and its crew of 8 returned to the surface on August 8, 2000 as part of a sizable effort. Upon recovery, Hunley was immediately brought to the Warren Lasch Conservation Center (WLCC) in Charleston, S.C to be excavated in a controlled environment. This paper will detail the inherent problems of handling a large and unstable 12-meter long iron submarine after 136 years of marine corrosion and will focus on the use of impressed current cathodic protection technologies.
