WASHINGTON (CNN) -- The commander of a U.S. Navy submarine has been relieved of duty after getting drunk with college officer-training students last week, according to Navy officials.

Cmdr. Jeff Cima led the Hawaii-based USS Chicago, a nuclear-powered Los Angeles-class fast-attack submarine, until Monday, when Navy officials said they had lost confidence in his ability to command and found him guilty of actions unbecoming of an officer, according to Navy spokesman Cmdr. Danny Hernandez.

The action is essentially career-ending, Hernandez said. Cima has been assigned to administrative duty in Hawaii, he added.

Last week, Cima attended a Reserve Officers Training Corps event in the continental United States where he became drunk, breaking regulations for a naval officer, Hernandez said.

ROTC is a college-based officer training program for the U.S. military.

Navy officials would not say where or what the event was because that would reveal other people involved in the event, they said.

According to the U.S. Navy Pacific Fleet's Web site, the new commanding officer of the USS Chicago is Capt. James E. Horten.

Cima was commander of the Chicago for almost a year, according to Navy officials.
