The command bridge , often called a bridge for short , describes the deck on a seagoing ship on which the sea ​​watch is held. Traditionally, the four-hour exchange the ship will go from here from nautical watch officer out.

The term “bridge” comes from the time of the paddle steamers , when a footbridge - a bridge - was built between the two wheel arches on which the skipper stood.

Strictly speaking, the bridge is the entire bridge deck and the closed part is the wheelhouse , also called the wheelhouse or rudder chair in inland shipping (English: wheelhouse , rudderhouse , in American-speaking countries also pilothouse ). The bridge thus consists of a wheelhouse or wheelhouse and cams. In parlance, however, the closed part is usually referred to as the bridge. This is intended to offer the officer on watch, commanding officer, etc., a favorable free position for maneuvering that is as protected from sea water as possible. A connection to superstructures on other parts of the ship is also called a gangway .

On both sides of the wheelhouse a close Nock or bridge wing (Engl. Bridge wing ) on a mostly non-covered part, is led from the ship during maneuvers of where and on duty deck officer performs during his watch certain activities, in particular compliance with the prescribed Route through continuous position determination and the consideration of shipping obstacles as well as the other sea vessels in the vicinity of the ship using technical aids such as radar and human observation .

In the wheelhouse are the command systems, such as the rudder , the engine telegraph , communication devices and the most important nautical instruments such as the magnetic compass. Part of the bridge is also the map room , in which the nautical charts are stored and navigation is operated at the coupling table . On modern ships, the chart room is rarely separated from the wheelhouse. The integration of the chart table into the wheelhouse itself became necessary in particular due to the introduction of the so-called one-man watch operation in ship operations, in order to ensure that the officer on watch can monitor the sea area and the traffic situation as well as perceive radio communication while doing chart work.

On submarines , the bridge, which is open at the top, is located on the tower of the boat and is only limited to the bow by the so-called bulwark , which runs up to chest height and protects the bridge crew from sea water. The bridge can therefore only be manned when the boat has surfaced. The wheelhouse and bridge cams are obsolete here; in the case of submarines from the time of the Second World War , however, there was often an aft corridor to the so-called " winter garden ".

In the case of large airships , the room with the control instruments was also referred to as the command bridge - precisely because they were "ships".

Inland vessels can have a retractable (lowerable) bridge in order to be able to pass under river bridges with low clearance.
