Murphy, a Navy lieutenant who grew up in Patchogue, N.Y., was posthumously awarded the Medal of Honor for his actions during a 2005 ambush. Military officials said that after his four-man team was surrounded, Murphy risked exposure to enemy fire so he could radio a base for help.

Navy Secretary Ray Mabus said the ship would guarantee that Murphy's story would be retold. U.S. Rep. Peter King heralded the young sailor for "unbridled courage." U.S. Sen. Charles Schumer recounted stories of how Murphy, since he was a child, had empathy for others.
