A focus was put on removing or minimizing flammable amidship materials. A continuous structure amidship increases internal volume and reduces radar cross-section. A two-deck high atrium is located by the entrance amidship. A second torpedo hit the minesweeper amidship and sank her. Engineers realized that the hull had broken amidship. Both amidship Dahlgrens nearest the boiler furnaces were fitted-out to fire heated shot. The bridge was located on a separate deck on top of the superstructure, almost amidship. Usually otter trawlers have the superstructure forward, though it can be aft or amidship. First-class cabins were positioned amidship, away from ocean movements and the vibration of the engines. Replenishment at sea can take place over the bow, over the stern, or amidship. The torpedo attack was successful and "Pedernales" was hit amidship. Five other shots struck "Tampico" at the waterline, one amidship. Two of the destroyers were hit amidship almost simultaneously and were severely damaged.
