Mobile Diving and Salvage Unit Two
Mobile Diving and Salvage Unit TWO, located at Naval Amphibious Base Little Creek, was originally established as Harbor Clearance Unit TWO on 01 October 1966. Patterned after World War II mobile salvage units, MDSU 2 consolidated the diving resources of the Atlantic fleet in order to clear harbors and waterways during the Vietnam War. The command officially became Mobile Diving and Salvage Unit TWO in February of 1982, reflecting the new focus on salvage operations specialized diving missions.
Over the years, MDSU 2 earned the title of "Experts in Salvage" through participation in such unique operations as the recovery of TWA Flight 800 and Swiss Air Flight 111, re-floating of YFU-83 in Puerto Rico, the salvage of the USS Monitor screw, and recovery of Haitian Ferry victims. Recently, the heavy salvage capabilities of MDSU 2 were demonstrated during the salvage of the Titan IV Spacecraft off the coast of Cape Canaveral. The mobile diving capability has allowed for completion of demanding and emergent tasking's such as the salvage of a SH-60 helicopter in 270 feet of water in the Red Sea.
In late 2002, MDSU 2 took part in the Monitor Expedition, an archeological effort to salvage portions of the Civil War ironclad.
