Ehime Maru and USS Greeneville collision

On 9 February 2001, about south of Oahu, Hawaii, in the Pacific Ocean, the United States Navy (USN) ''Los Angeles''-class submarine USS ''Greeneville'' (SSN-772) collided with the Japanese fishery high-school training ship from Ehime Prefecture. In a demonstration for some VIP civilian visitors, ''Greeneville'' performed an emergency ballast blow surfacing maneuver. As the submarine shot to the surface, she struck ''Ehime Maru''. Within ten minutes of the collision, ''Ehime Maru'' sank. Nine of the thirty-five people aboard were killed: four high school students, two teachers, and three crew members.

Many Japanese people, including government officials, were concerned by news that civilians were present in ''Greeneville'' control room at the time of the accident. Some expressed anger because of a perception that the submarine did not try to assist ''Ehime Maru'' survivors and that the submarine's captain, Commander Scott Waddle, did not apologize immediately afterwards. The USN conducted a public court of inquiry, blamed Waddle and other members of ''Greeneville'' crew, and dealt non-judicial punishment or administrative disciplinary action to the captain and some crew members. After Waddle had been questioned by the Naval Board of Inquiry, it was decided that a full court-martial would be unnecessary, and he was forced to retire and given an honorable discharge.

In response to requests from the families of ''Ehime Maru'' victims and the government of Japan, the USN raised ''Ehime Maru'' from the ocean floor during October 2001 and moved it to shallow water closer to Oahu. Once there, USN and Japanese divers located and retrieved the remains of eight of the nine victims from the wreck. ''Ehime Maru'' was then moved back out to sea and scuttled in deep water. The USN compensated the government of Ehime Prefecture, ''Ehime Maru'' survivors, and victims' family members for the accident. Waddle traveled to Japan in December 2002 to apologize to the ship's survivors and victims' families.

The accident renewed calls by many in Japan for the United States to make more effort to reduce crimes and accidents involving U.S. military personnel who injure or kill Japanese citizens. In response to the accident, the USN changed its policies regarding civilian visits to its ships. Provided by Wikipedia
