|Mobile Diving and Salvage Unit ONE
Mobile Diving and Salvage Unit ONE was commissioned as Harbor Clearance Unit ONE in February 1966 in Subic Bay, Republic of the Philippines.
The command was immediately put to the test in Vietnam.
During the Conflict, salvage teams conducted numerous harbor clearance operations in Vietnamese rivers, harbors, and coastal areas.
The unit's professionalism resulted in the command being awarded the Meritorious Unit Commendation and Presidential Unit Citation.
At the conclusion of the Vietnam conflict the command was relocated to Pearl Harbor, Hawaii.
In 1979 the unit's mission was expanded to include responsibility for providing diving services to all Pearl Harbor based surface ships.
In January 1982 the unit's name was changed from Harbor Clearance Unit ONE to Mobile Diving and Salvage Unit ONE to better reflect the capabilities of the unit.
In 2001, MDSU ONE was involved in recovery efforts following the sinking of the Japanese fishing vessel, EHIME MARU.
MDSU ONE divers successfully recovered the remains of eight of the nine lost fishermen as well as their personal affects.
In 2003, MDSU ONE personnel took part in OPERATION IRAQI FREEDOM when they conducted Combat Harbor Clearance in the port of Umm Qasr, Iraq.
Over twenty derelict Iraqi patrol boats were cleared from the harbor.
MDSU ONE's efforts in Iraq allowed rapid entry of humanitarian supplies into the port, greatly enhancing the war effort.
In the same year, MDSU ONE personnel were involved in defueling operations of a World War II oiler sunk in 1945 by a Japanese Kaiten (manned suicide torpedo).
The ex-USS Mississinewa was found to be leaking oil and threatening the local islands in the Ulithi Atoll, Micronesia.
MDSU ONE divers, in conjunction with the USS SALVOR successfully removed two millions gallons of fuel from the ship.
MDSU ONE also participates in annual Fleet exercises around the Pacific including:
FOAL EAGLE, COBRA GOLD, RIMPAC, NORTHERN EDGE, TALISMAN SABER and CARAT.
MDSU ONE personnel have recently deployed to Iraq, Afghanistan, Dubai, Sri Lanka, North and South Korea, Vietnam, Philippines, Thailand, Laos, Australia, Micronesia, Guam, Palau, Kwajalein Atoll, and Alaska in support of the command&'s mission.
MDSU ONE has a proud history of getting the job done right.
This is a direct reflection of the outstanding professionalism shown by the many men and women who have served as "MDSU Sailors" during the unit's years of service.
