All but 3 battleships at pearl harbor were returned to service. of those three only one ship (Utah) which was an old ship used only for target practice went unscrapped. The other two still had their guns taken and put on other ships. Even if the aircraft carriers were at PH that day, we would have had them back in service regardless. The oil really was the only unreplacable thing at PH that day and it was left untouched. The drydocks being taken out was even more critical which were also planned for the third wave.
