U.S. and Japanese officials gathered in Honolulu to remember nine crewmembers who died when a Navy submarine rammed into a Japanese fishing school ship off Oahu 12 years ago.

Ehime Vice Gov. Keiji Joko and Hawaii Gov. Neil Abercrombie joined Honolulu Mayor Kirk Caldwell and others at Kakaako Waterfront Park for a memorial ceremony Saturday.

Nine boys and men were killed when the USS Greeneville struck the Ehime Maru, slicing its hull. Twenty-six people were rescued from the Ehime Maru. No injuries were reported on the 360-foot nuclear-powered sub.

A Navy investigation concluded the Greenville’s captain rushed through mandatory safety procedures while demonstrating an emergency surfacing drill for the benefit of civilians touring the submarine.
