USS Oscar Austin (DDG 79) is an Arleigh Burke-class destroyer in the United States Navy. USS Oscar Austin is named for Medal of Honor and Purple Heart recipient Private First Class Oscar P. Austin.
On February 12, 1969, Austin's observation post, near Da Nang, was attacked by a large North Vietnamese force. Austin's fellow Marine was wounded, and Austin went over to help him. Austin jumped onto an enemy grenade landing near the wounded man and suffered severe injuries, and then protected his fellow Marine by jumping between him and a shooting the enemy soldier. He was mortally wounded during this action, and was posthumously awarded the Medal of Honor.
