Did Japanese midget submarines sink the Arizona?

[Jimbuna]

She was hit by several bombs, one of which penetrated her forecastle and detonated her forward ammunition magazines.

The Arizona came under attack almost immediately, and at about 8:10 received a hit by a 800-kilogram bomb just forward of turret two on the starboard side. Within a few seconds the forward powder magazines exploded, gutting the forward part of the ship. The foremast and forward superstructure collapsed forward into the void created by the explosion and turrets one and two, deprived of support, dropped more than 20 feet relative to their normal position.
