Continuing our tour aft on board HMCS Ojibwa, we have passed through the accommodation space with its assorted messes and berths. The photo to the left is part of the starboard side of the control room, featuring the chart table, a prominent red light bulb, various communication outlets, a clock, etc.
And to the right is an image of part of the port side of the control room under red lighting conditions.
The red lighting is switched on at dusk and off at dawn, even when running at great depth, in case it is necessary to surface in a hurry. Also, if at periscope depth, it allows the periscope watchkeeper's eyes to be adjusted for night vision.
Not shown in either photo are the periscopes, which are on the centre-line of the boat, with the attack (monocular) periscope forward of the search periscope, which is binocular.
