She was the fifth ship of the U.S. Navy to bear the name.〔Pike, 2005.〕 She was built in Massachusetts in 1972 and homeported in Southern California for 31 years until being decommissioned on 25 July 2003. ''Mount Vernon'' acted as the control ship for the cleanup of the Exxon Valdez oil spill. In 2005, she was intentionally destroyed off the coast of Hawaii as part of a training exercise. ==History== ''Mount Vernon'' was awarded to General Dynamics Quincy Shipbuilding Division in Quincy, Massachusetts on 25 February 1966.〔 After commissioning in Boston Naval Shipyard in 1972, she was homeported in San Diego, California.〔 In April 1975, ''Mount Vernon'' participated in Operation Frequent Wind, the evacuation of Saigon, Vietnam.〔(By Sea, Air and Land: An Illustrated History of the U.S. Navy and the war in Southeast Asia Chapter 5: The Final Curtain, 1973-1975 )〕 Beginning 22 July 1985, ''Mount Vernon'' was briefly homeported in Long Beach, California before returning to San Diego.〔 In her 31 years of service, ''Mount Vernon'' completed 15 deployments in the U.S. Seventh Fleet in the Far East.〔 Because of the remote location of the cleanup sites of the ''Exxon Valdez'' oil spill,〔 there was a desperate need for floating facilities to house shoreline cleanup workers.〔McDonnell (1992), p. 28.〕 In response, the Navy provided amphibious transport docks and dock landing ships (LSDs).〔 The arrived in Alaska on 24 April 1989 followed by the on 4 May 1989.〔 Over the summer months the Navy replaced the ''Juneau'' first with the and the , and then with the .〔 Meanwhile, the ''Mount Vernon'' relieved the ''Fort McHenry'' and then left the cleanup operations on 18 July without a replacement, reducing the naval presence to one ship.〔 The ''Duluth'' sailed without replacement on 16 September, ending the naval ship presence in the oil spill cleanup operations.〔 The ships functioned as floating hotels, providing medical, laundry, housing, dining, and sleeping facilities for shoreline cleanup workers.〔 They also provided communications support and functioned as command and control platforms and helipads for the forward deployment of helicopters.〔 They supported base operations of the landing craft, providing maintenance, fuel, and docking. Deployed with the ships were Marine Corps CH-46 helicopters and Army medical evacuation helicopters, which performed a variety of essential missions.〔 Naval ship operations centered in Prince William Sound and were especially important in open sea areas because commercial berthing vessels could not operate in the rough water.〔 During her career, the ''Mount Vernon'' accumulated many awards, including: *Joint Meritorious Unit Award,〔Priolo, 2005.〕 *Navy Meritorious Unit Commendation,〔 *Navy Battle "E" Ribbon, (2),〔 *National Defense Service Medal,〔 *Armed Forces Expeditionary Medal, (4),〔 *Southwest Asia Service Medal,〔 *Humanitarian Service Medal, (2),〔 *Coast Guard Special Operations Service Medal,〔 and the *Kuwait Liberation Medal.〔 The ''Mount Vernon'' was decommissioned on 25 July 2003.〔 Afterwards, she stayed at the Naval Inactive Ship Maintenance Facility, in Pearl Harbor, Hawaii.〔 On 16 June 2005, she was sunk in a fleet training exercise for P-3 Orion squadrons VP-1, VP-9, VP-46, and VP-47.〔 The sinking was part of operation "Patrolling Thunder" and took place off the northwest coast of Kauai, Hawaii.〔 Expended in the sinking were 3 Harpoon missiles, 4 Maverick missiles, and 18 bombs of 500 pounds apiece.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS Mount Vernon (LSD-39)」の詳細全文を読む スポンサード リンク
