The "Don't Ask, Don't Tell" policy prohibiting openly gay, lesbian, or bisexual people from military service was repealed on September 20, 2011. The Navy had trained over 400,000 personnel on the repeal and its chief of naval operations thanked sailors for their professional conduct during the transition process. Under the repeal, sexual orientation alone will no longer bar military service and standards of conduct will remain the same for all sailors regardless of orientation.
