USS Lassen (DDG-82) is an Arleigh Burke-class guided missile destroyer in the United States Navy. Her current commanding officer is Commander Scott C. McClelland.
She was homeported in San Diego until she shifted homeport to Yokosuka Naval Base in Yokosuka, Japan in August 2005, where she remains as of January 2011.
Lassen is named for Clyde Everett Lassen, who was awarded the Medal of Honor for his courageous rescue of two downed aviators while commander of a search and rescue helicopter in Vietnam.
On 15 February 2009 at 12:25 pm, Lassen collided with a Japanese 14-ton pleasure boat in Yokosuka harbor. Four people fishing on the pleasure boat, which was at anchor, were reportedly uninjured. On 23 March 2009 the Japan Coast Guard filed a case against both the destroyer's and the fishing boat's captains with local prosecutors for professional negligence that endangered traffic.
On 1 July 2009, Fox News Channel reported that Lassen was tracking the North Korean ship Kang Nam, suspected of carrying contraband.
