Submarine Periscope

Submarine periscopes are optical devices used on submarines to provide visual observation above the water's surface while the submarine remains submerged. They are a part of the supply class called Optical Sighting and Ranging Equipment, which includes various optical devices used for sighting and ranging purposes.

In the supply group Fire Control Equipment, submarine periscopes are specifically used for fire control purposes. Fire control equipment is responsible for accurately aiming and targeting weapons systems, ensuring precise and effective engagement of targets.

Submarine periscopes typically consist of a series of lenses and mirrors that allow the user to view the surrounding area without exposing the submarine's hull above the water. They are usually mounted on a rotating mast, allowing for a 360-degree view. Some periscopes may also include additional features such as infrared or night vision capabilities to enhance visibility in low-light conditions.

Overall, submarine periscopes play a crucial role in the fire control system of submarines, providing visual information to the crew for target acquisition and engagement.
