To the right of the memorial, you can see the quay where the Arizona was moored. At the left end, you can see the visitors getting on the boat to be ferried back
to the museum. The rusty protuberance in front of the memorial is the base of gun turret number 3.

According to the designer of the memorial:

The sag in the center indicates our initial defeat, while the uplifted ends signify our ultimate victory.
The design at the end (the windows in the shrine room) signifies the tree of life.

The USS Missouri, while not commissioned at the time of the Pearl Harbor attack, was the ship on which the Japanese surrender was signed.

If I recall correctly, it also saw action in Gulf War I, and was decommissioned fairly recently. It shows you sort of what the Arizona looked like before she was attacked.

Each white block shows where a battleship was anchored that morning.
These quays have now been painted white, and labelled with the name/number of the ship that moored there.

The names of all the sailors/Marines from the USS Arizona who died that day are etched in this marble wall. One thousand, one hundred seventy-seven of them.
There is a portion of the wall, in the far left lower corner with significantly fewer names on it. It lists the survivors of the Arizona who chose to be interred with their
shipmates when they died.

Called "The Pearl Harbor Avenger", this submarine was responsible for killing over 20 Japanese ships during the war.

This is a model of the Memorial... it shows the battleship, as it lies underwater, and the memorial built over it.
