Thus, the conning tower effectively became the boat's dedicated attack center, from which the commanding officer would command the boat whilst submerged. Some late 1930s designs even located their <a href="/wiki/Hydrophone" title="Hydrophone">hydrophone</a> and <a href="/wiki/Radar" title="Radar">RADAR</a> operators' stations inside this compartment to maximize the commander's situational awareness. </p><p>In addition to their primary purpose, conning towers also served as elevated attachment points for air intakes, <a href="/wiki/Magnetic_Compass" class="mw-redirect" title="Magnetic Compass">magnetic compasses</a>, and even collapsible <a href="/wiki/Bridge_(nautical)" title="Bridge (nautical)">open air bridges</a>. As conning towers were eventually built large enough that crewmen could comfortably stand on top of them, the collapsible bridges gave way to fixed structures, leading to the development of the so-called "bridge fairwater". To clarify: </p> <ul><li>The conning tower is the small watertight compartment above the control room, from which the boat's commanding officer would command the boat during submerged attacks.</li> <li>The bridge was built on top of—but not considered part of—the conning tower, and was used for surfaced navigation and signalling.</li> <li>The fairwater is a streamlined casing around the conning tower and/or around the bridge. The tapering aft end of this casing also provided a sheltered location for the boat's air intakes, as well as an elevated base for various <a href="/wiki/AA_gun" class="mw-redirect" title="AA gun">AA gun</a> (anti-aircraft) platforms.</li></ul> <p>In the post-1950s era, an increased focus on deep submerged operation, together with improvements in technology that allowed periscopes to be made longer, removed the need for a raised conning station. <a href="/wiki/USS_Triton_(SSRN-586)" title="USS Triton (SSRN-586)">USS <i>Triton</i></a> (laid down 1956) was the last US submarine to have a conning tower, after which the conning tower's function as an attack center was integrated into the <a href="/wiki/Control_room" title="Control room">control rooms</a> of subsequent designs.
