The problem with the theory that a midget sub torpedoed the
Arizona is the fact that the
Vestal partially blocked the shot. They are the last pair on the left. The
Vestal was 470 feet long, the
Arizona 610 feet, a difference of only 140 feet. Doable, but a tight shot.
It is much more likely that a sub would have targeted either the
West Virginia or the
Oklahoma, both of which were wide open.
