Navy Commissions USS Arlington

NORFOLK, Va. -- A Navy ship named in honor of the victims and first responders of the 9/11 attack on the Pentagon joined the fleet Saturday, serving as a floating tribute to the people who died that day and an active warship that can transport Marines around the world. The Navy commissioned the USS Arlington in front of about 5,000 people in its new home port of Naval Station Norfolk. The amphibious transport dock is one of three ships named after 9/11 crash sites. Two hundred pounds of steel salvaged from the Pentagon's wreckage was forged into a pentagon to be put on a permanent display aboard the ship in a memorial room and smaller pieces of the Pentagon sit on the commanding officer's desk. The ship also has 184 gold stars throughout its passageways in honor of those who died when American Airlines Flight 77 crashed into the Pentagon on Sept. 11, 2011. (AP)
