In this air-conditioned room in the center of a most complete radio and radar section of the ship, the whole or part of an amphibious operation (depending on the operation) is directed and coordinated. Liaison officers of Navy and Army work elbow to elbow giving each other immediate and necessary directives to coordinate the attack. Everything that goes in the operation is immediately known by radio and radar and bulletins are projected on the two screens seen in the two corners of the room. This is done by the sailor operating a new teletype machine that automatically projects the typewritten messages on the two screens seen and three others located in other parts of the ship. The doorway at the right of the picture leads into the radar room.
