The sonar antennas, search radar, snorkel and periscopes would extend through the top of the superstructure. When surfaced, crew members would stand watch on the bridge at the top of the sail.
Conning Tower: This small watertight compartment inside the sail above the control room would protect critical equipment and command crew during a battle. Triton was the last U.S. submarine with a conning tower.
