#HUNLEY SUBMARINE PLANS FULL#
Hunley submerged in a water tank, instead of exposing it to the oxygen-rich air, until a full conservation plan could be created. However, to prevent more rust from forming, the conservators choose to keep the H.L. Hunley was made of iron and was submerged for over a hundred years, rust had formed all over the submarine. It can also occur when the moisture content of the air surrounding the metal is high. Rust occurs naturally when iron or steel is submerged in water and exposed to oxygen. Types of deterioration present on the H.L. Lasch accepted the challenge in 1997 and became the chairman of the Friends of the Hunley.

The Hunley was sent to Lasch Conservation Center at the old Charleston Navy Yard for conservation. Cussler claims to have discovered it in 1995, and Spence says he discovered it in 1970 but failed to validate the discovery by diving in the location. Lee Spence both claim to have made the original discovery. Well-known author Clive Cussler and underwater archaeologist E.
There is some controversy about who located the actual position of the Hunley. The divers had to dive down 30 feet of water before finding the Hunley, which was buried in the sand and sediment. Hunley was found in 1995 in the Charleston outer harbor about four miles off Sullivan’s island. The Hunley was unable to get enough distance and was also fatally damaged, though it may have survived up to an hour after the detonation.ĭiscovery and recovery of the H.L. The Hunley rammed the Housatonic to embed the torpedo in her hull and then reversed course while the lanyard connected to the torpedo fuse tightened and detonated it. On February 17, 1864, the Hunley destroyed the Union sloop Housatonic outside Charleston Harbor using a spar-mounted torpedo loaded with 135 pounds of gunpowder. The Hunley was lost to the Charleston outer harbor until 1970 and was finally recovered in 2000. The first two times were during test runs, and the final time was during its attack of the USS Housatonic (1861). The Hunley sank three times during its short career. It was propelled by a hand cranked propeller and held a crew of one officer and seven enlisted men. Hunley is a civil war confederate submarine built in 1863 by Park & Lyons Hunley, McClintock & Weston. Currently visitors can tour the conservation center laboratories and can view the Hunley in its 75,000-gallon tank. Once the Hunley 's conservation and restoration is complete it will be relocated to a new museum built in its honor on the former Navy base in North Charleston. The Hunley, the first combat submarine to successfully complete its mission, has been at the Lasch Conservation Center for over 15 years while scientists and conservators formulate a plan for its restoration. Lee Spence and recovered from the ocean in 2000, a team of conservators from the Lasch Conservation Center has been working to restore the Hunley. Since the Hunley was located in 1970 by Dr. Hunley is currently being undertaken by the Warren Lasch Conservation Center they hope to have the Hunley project completed by 2020. 6, 1863 PSM V58 D167 Confederate submarine which sank the Housatonic Conrad Wise Chapman – Submarine Torpedo Boat H.L.
