The periscope is used by the submarine to look around the surface of the water, while the rest of the submarine is under water. It makes the submarine harder to find and destroy by enemy antisubmarine warfare. The periscope might be just a simple set of mirrors or it might have a "heads up display", similar to HUD found in some combat aircraft, that give the range to the target, as well as a magnifying glass that also makes the target easier to see, similar to a pair of binoculars.
