The periscope is the eye of the submarine. It was invented and developed solely for the purpose of providing a means to view the surface without fear of detection by surface craft. While it is primarily simple in principle, actually it is a complicated piece of apparatus.

More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other.

Jul 1, 2021 · The US and UK are both fielding submarines equipped with new photonic and optronic masts that replace the periscope entirely while ensuring submariners can still see their targets on the surface.

Periscope, optical instrument used in land and sea warfare, submarine navigation, and elsewhere to enable an observer to see his surroundings while remaining under cover, behind armour, or submerged. A periscope includes two mirrors or reflecting prisms to …

Oct 8, 2023 · First introduced in the early 20th century, periscopes revolutionized submarine warfare and exploration by providing a means to observe the world above water without surfacing. Essentially, a periscope is an optical instrument consisting of prisms, mirrors, and lenses.

This periscope developed for the Polaris submarine is capable of taking automatic star sights to allow the submarine to determine and maintain its position with an accuracy of seconds of arc. At the same time, new and varied intelligence and surveillance missions of some attack submarines brought about additional fresh periscope requirements.
