Lookouts
Good lookouts are absolutely essential to a ship’s safety. They have one of the most important positions on the ship. On their alertness depends the discovery of any submarine or suspicious object in his arc of lookout and the immediate and accurate reporting of it to the fire control officer, so that the guns may be brought into action in the quickest possible time against the enemy.
There were twelve lookout stations on this vessel—six on each side—so arranged that each lookout had an arc of thirty degrees to keep under close observation. Of course there were additional lookouts on watch at all times, such as the gun crews, control officers, signalmen and officers-of-the-deck. Each tried to be the first to spot a hostile periscope.
