Most of the Pearl Harbor oil tanks were exposed to air attack.

The tanks above ground are both storage and transfer tanks, and are relatively small in volume compared to the cavern storage facilities, which are enormous. But that is today, it may have been different in WWII, that I am not sure of.

Even more important to the Japanese war effort than the oil would have been the destruction of the PH drydocks & repair facilities that were to used to repair our sunken BBs, as well as the flattops following the first few hard months of fighting in the Pacific.

It would've been so easy to do and the effect would have been significant.
