 As a result of the defeat , new procedures were adopted whereby more Japanese aircraft were refueled and re @-@ armed on the flight deck , rather than in the hangars , and the practice of draining all unused fuel lines was adopted . The new carriers being built were redesigned to incorporate only two flight deck elevators and new firefighting equipment . More carrier crew members were trained in damage @-@ control and firefighting techniques , although the losses later in the war of Shōkaku , Hiyō , and especially Taihō suggest that there were still problems in this area .
