The U.S.S Arizona is a Pennsylvania-class battleship built for the United States Navy in the mid 1910s. It was named in honor of the 48th state of the United States. On the morning of December 7, 1941, Arizona was bombed. When the bomb hit the power magazine, the battle ship exploded violently, and unlike other ships that were struck, Arizona's damage was beyond repair because of the extreme force of the explosion. As a result, 1,177 oficers and crewman died. Despite the damage, the Navy took some parts from the ship and they were used in other ships built later.
Season 7, Episode 22, focuses partly on the murder of one of the last survivors of Arizona.
